The system analyzes medical claim items, some of which have principal diagnosis codes, and some of which have non-principal, missing, or incorrect diagnosis codes. Patient treatment episodes (PTEs) are formed from the principal diagnosis codes, each PTE being of a particular diagnostic cluster type. The system categorizes non-principal-diagnosis claim items into the PTEs on the basis of temporal, physiological or clinical relationships between the claim items and the PTEs. A drug lookup table enables drug claims to be properly categorized in the PTEs. A diagnostic cluster lookup table enables claim items to be categorized into PTEs with ongoing treatment windows for which the diagnosis code of the claim item is in the diagnostic cluster lookup table. The system merges PTEs of the same diagnostic cluster type when the treatment windows of the PTEs overlap. The system attempts to recategorize medical claims into merged PTEs. The system analyzes each PTE to determine the presence of required diagnoses and eliminates any PTE without a required diagnosis. The system also identifies and merges PTEs that are clinically related or clinically similar. In a system for integrating medical claims data, medical claim items that are in different data formats and/or use different coding systems are analyzed, and related claim items are categorized in a common coding system.

The Strangely Beautiful Tale of Miss Percy Parker: Amazon.co.uk: Leanna Hieber: Books
The Strangely Beautiful Tale of Miss Percy Parker [Mass Market Paperback] Leanna Hieber (Author)
Publication Date: 1 Sep 2009 | Series: Strangely Beautiful
What fortune awaited sweet, timid Percy Parker at Athens Academy? Hidden in the dark heart of Victorian London, the Romanesque school was dreadfully imposing, a veritable fortress, and little could Percy guess what lay inside. She had never met its powerful and mysterious Professor Alexi Rychman, knew nothing of the growing shadows, of the Ripper and other supernatural terrors against which his coterie stood guard. She saw simply that she was different, haunted, with her snow white hair, pearlescent skin, and uncanny gift. This arched stone doorway was a portal to a new life, to an education far from what could be had at a convent-and it was an invitation to an intimate yet dangerous dance at the threshold of life and death...

The Boy with the Cuckoo-Clock Heart by Mathias Malzieu Hardcover
Format:Mass Market Paperback I picked this up because it was recommended as a Victorian gothic demon guarding novel with prophecies. Unfortunately, this turned out to be an illusion. Instead, I got a fragile albino heroine that is actually beautiful and fabulous at everything except maths and who swoons quite a bit, who flirts with her Byron-esque professor, who seems to constantly have a smile tugging at the corners of his mouth and who smiles and encourages all innuendo and flirting despite going on about how he can't get involved with a student.This becomes tedious. In fact, the whole Victorian 'la, sir' and blushing thing gets tedious very fast. I prefer my heroines with a little more guts and less Mary-Sue and I definitely want a hero who isn't a weird prudish sleaze. Just avoid.
Engaging and mysteriously charming...Hieber channels Radcliffe in this Dangerously Lovely Tale.
Format:Mass Market Paperback One of the most mesmerizing characteristics of Leanna Renee Hieber's novel is its overwhelming gothic presence. The Strangely Beautiful Tale of Miss Percy Parker might take place in Victorian England, yet its distinct voice conjures up roots of the earlier gothic period. Readers will instantly embrace this, as I did. Her language brings to mind lonely moors, and dashing highwaymen plundering in the thick of the night.The overall feel of the novel, which places it at the height of the Ripper years, and Victorian theosophy is chock full of sinister tones, nostalgia, innocence, and the sprightly passion of its characters. Hieber's strength is on the palpable conflict between its two main leads: Alexi and Percy and their inner turmoil. While there was no bodice ripping to be found, the sheer acute sense of longing between these two enigmatic characters fairly sets the pages ablaze. Plenty of pleasantly overwrought situations can be found within the covers of Hieber's tale, but all are extremely fitting for such a deceptively titled story... and housed in such demure packaging. I ABSOLUTELY loved this book.The Strangely Beautiful Tale of Miss Percy Parker comparatively resonates the influence of Ann Radcliffe. This fable was sweet, dangerously lovely, and at many times scintillating, as the balance for good and evil is fought at the frontlines of London. Come join the searing battle against Cerberus, a false prophet, and their minions as they lead an onslaught to break the seals of Hell beneath the ancient city. Where The Guard makes their last stand as they await the prophecy of a Seventh to be revealed at their direst hour. And the love for a lonely Professor gives an otherworldly girl the courage to face her fate, her unlikely visage, and face Hell itself. Bravo!

The pallet of claim 1 wherein the top comprises an injection molded frame which forms the periphery of the top; wherein said sheets are comprised of two thermoformed sheets welded to each other and to the frame. 11. The pallet of claim 1 wherein the top comprises an injection molded frame which forms the periphery of the top; wherein said bottom sheet is injection molded and integral with the frame; and wherein said top sheet is a thermoformed sheet. 12. The pallet of claim 1 wherein said truncated conical depressions are have circular cross sections. 13. The pallet of claim 5 wherein a portion of said depressions have oblong shapes, for enabling manual grasping of the pallet. 14. The pallet of claim 1 wherein the top, columns and base are is predominately made of a high density polyethylene or polypropylene; and, wherein said rigid foam is polyurethane. 15. A pallet for transporting goods, comprising: a base, comprised of outer rails running in a rectangular pattern and cross rails connecting the centers of opposing side outer rails; metal beams within the rails of the base; eight peripheral columns and one center column extending upwardly from the base; a rectangular top mounted on the peripheral columns, for receiving goods, the top comprising a frame and a rectangular deck, wherein the periphery of the deck is attached to the frame, and the center of the deck is attached to said center column; wherein the deck comprises: a top sheet having a substantially planar upper surface, for receiving goods placed on the pallet, and a multiplicity of spaced apart truncated conical depressions; a bottom sheet, spaced apart from and substantially parallel to the first sheet; and, rigid plastic foam with the space between the sheets; wherein the sheets are joined together along their outer edges and at the locations of each of said truncated conical depressions; and, wherein the deck has a multiplicity of holes located within the bottoms of said top sheet depressions, for passage of water or air through the deck. 16. The pallet of claim 15 wherein the bottom sheet has a multiplicity of spaced apart depressions; wherein said depressions of each sheet have flat bottoms with center holes; and wherein the depressions are connected to each other at their flat bottoms. 17. The pallet of claim 14 wherein a portion of said depressions have oblong shapes, for enabling manual grasping of the pallet, said oblong depressions located proximate the corners and center of the pallet 18. The pallet of claim 15 having the configuration of a GMA pallet with a top which is 40 inches by 48 inches in rectangular dimension; and wherein there is at least one depression for every 25 square inches of deck surface. 19. The pallet of claim 15 having the configuration of a GMA pallet with a top which is 40 inches by 48 inches in rectangular dimension, wherein the diameter of each depression at the top surface of the upper sheet is greater than three percent of the dimension of any side of the pallet. 20. The method of making a pallet for transporting goods, wherein the pallet comprises a base, a multiplicity of spaced apart columns extending upwardly from the base, and a top mounted on the columns which top comprises a frame and a rectangular deck attached to the frame; wherein the deck comprises a top sheet having a substantially planar upper surface, for receiving goods placed on the deck; a bottom sheet, spaced apart from and substantially parallel to the first sheet; and, rigid plastic structural foam with the space between the sheets, connecting sheets; wherein, both sheets have a multiplicity of spaced apart truncated conical depressions; and, wherein the sheets are attached to each other at their edges and at the locations of said truncated conical depressions; which method comprises: a) injection molding plastic to form a body which comprises said frame, said bottom sheet of said deck with said multiplicity of depressions according to a first pattern; b) thermoforming plastic sheet to form a top sheet of the deck, the deck having a multiplicity of spaced part truncated conical depressions in a pattern which mirrors said first pattern; c) welding the top sheet to the body, so the periphery of the frame is attached to the frame and so the bottoms of the depressions are attached to the bottoms of the depressions of the bottom sheet; wherein the sheets are spaced apart from each other except where they are welded; and, d) injecting plastic material into the space between the sheets to form a rigid foam their, where the form is bonded to the sheet surfaces. 21. The method of claim 20 which further comprises the steps of placing metal beams upon the first sheet before carrying out step (c), so the beams are included within the foam which is formed.
This application claims benefit of provisional patent application Ser. No. 10/657,379, filed on Mar. 1, 2005.
TECHNICAL FIELD The present invention relates to molded plastic pallets, of the type used with forklift devices for transporting goods. BACKGROUND Commercial plastic pallets for use with fork lift devices have often been made of familiar thermoplastics, which would appear to provide them with a number of potential advantages over wood pallets, including better durability and moisture resistance. A common plastic pallet, which can be made in the present invention, is often referred to in the U.S. as a GMA pallet. It has a 40 inch�48 inch rectangular base, eight columns running up from the periphery of the base, and a rectangular deck. A comparable European pallet is a 1000 mm by 1200 mm pallet. The Grocery Manufacturers of America (GMA), Washington, D.C., U.S., in conjunction with other organizations, has published a document entitled �Recommendations on the Grocery Industry Pallet System� (1992). From that and other references, for a GMA pallet to gain acceptance by large commercial users in the U.S. it must have certain dimensions and meet strength and durability requirements. �Recommended Test Protocol for Plastic Pallet, Version 3� (1998) published by Virginia Tech, Blacksburg, Virginia, U.S., sets forth mechanical performance and test requirements for pallets including a warehouse racking test. ISO 8611:1991 and proposed Underwriters Laboratories (UL) Standard 2417 specify similar mechanical performance and testing standards. UL Standard 2335 specifies fire tests and performance for warehouse pallets made of plastic. The disclosures of the foregoing documents are hereby incorporated by reference. Commercial purchasers may have their own standards which can be somewhat more demanding. When pallets are uses in connection with food goods, they often must meet the requirements of the U.S. Food and Drug Administration, such as those at Section 7 of American National Standard/NSF International Standard No. 2 (ANSI/NSF 2-1996), hereafter called NSF requirements or NSF standards. Among the requirements are that a pallet ought not to have small cavities or crevices which could harbor microorganisms and insects, or which are hard to clean. There are also limitations on the kinds of exposed metals which can be used. Pallets for transporting food goods also often have to sustain frequent sharp temperature changes. In pallets not specifically intended for use with food goods, it is quite common to have ribbed and perforated decks, since that helps minimize the weight and cost of plastic in the pallet. However, although the decks embody good plastic structural design, they are not helpful in meeting NSF requirements. On the other hand, if the deck is a smooth continuous surface, then the resultant lack of means for draining and air circulation is disadvantageous. So, there are conflicting aims which the present invention seeks to resolve. Another barrier to the success of many plastic pallets has been an inability to also meet the demanding mechanical strength requirements of GMA pallets. One way of achieving strength has been to incorporated steel beams within the tops and bases of plastic pallets, See U.S. Pat. No. 6,705,237 of Moore et al., No. 6,955,128 of Apps et al., and No. 5,868,080 of Wyler et al. However, if such beams are exposed, or if there are narrow crevices in their vicinity, then the NSF requirements may not be met. Other problems associated with the use of steel beams can be thermal fatigue which arises from differential thermal expansion, and unacceptable increases in pallet cost or weight. Thus, there is a need for continuing improvements in pallets used for carrying food goods, to meet the various technical requirements. Any improved pallet must also be economic to manufacture and low in weight. SUMMARY An object of the invention is to provide a pallet with features which meet both the GMA and NSF requirements, and which are economic to make. A further object is to provide a plastic pallet for use in food service, which pallet is strong and light and which is free of a multiplicity of recesses and crevices, especially with respect to the deck. In accord with the invention, a pallet has a rectangular top which comprises a deck made of two spaced part sheets, at least one of which has a multiplicity of spaced apart truncated conical depressions. The sheets are attached to each other at the locations of the depressions and at their edges. The space between the sheets is filled with rigid plastic structural foam. The foam enables the top sheet to resist impact loads, and provides bending strength to the deck and pallet as a whole. Preferably, metal beams run diagonally from corner to corner in an x-pattern between the sheets and within the foam material of the deck. The pallet preferably has a frame which forms the periphery of the top and the deck attached to the frame, so it is inset from the outer edge of the top. In an embodiment of the invention, mating flat bottom circular conical depressions are present in both the top sheet and the bottom sheet. The flat bottoms of the mating depressions are welded to each other at the approximate center plane of the deck; and there is a hole for passage of water or air through the deck at the bottom of each depression. In alternative embodiments, the depressions may be present in one sheet only and the other sheet may be flat; and, some of the depressions have an oblong shape so they are suited for manual grasping of the pallet. The depressions are large, compared to features of decks in the past. The depressions are arranged in four spaced apart arrays having the approximate shape of equilateral triangles; thus, there are regions between the arrays where the x-pattern beams run. In an embodiment of the invention, the pallet is shaped like a GMA 40�48 pallet. The pallet has a base, columns extending upwardly from the base, and a top mounted on the columns, for receiving goods. The base is comprised of rails arranged in a rectangular pattern; and the deck has aforesaid x-pattern of beams. The diameter of each depression is at least 3 percent of the length or width of the deck, and there is at least one depression for every 25 square inches of deck area. The pallet is preferably made of thermoplastic, such as high density polyethylene or polypropylene, the rigid foam is made of polyurethane and the beams are made of steel. In one mode of constructing the pallet, the deck is fabricated separately from the rest of the pallet by making and joining together two thermoformed sheets. When joined together, with placement of the metal beams, if desired, foam plastic is formed between the sheets. Then the deck is welded to an injection molded top or frame of the pallet. In another mode of constructing the pallet, a pallet body is made by injection molded of plastic; the bottom sheet has depressions and is formed as an integral part of the frame of the body, which provides various advantages including more uniform thickness sheet and fewer potential crevices. The top sheet is thermoformed and attached to the bottom sheet edges and depressions, after placement of the beams. In both embodiments, the rigid foam is formed by injection of material into the space. The metal parts are sealed within the plastic of the pallet and thus are protected from contact with food goods and corrosion. The combination of a two-sheet deck having rigid plastic foam, metal beams within the deck interior, and metal beams in base, provides good strength to a pallet. The large depressions in the surfaces of the deck are easily cleanable; and the simplicity of design means there is an absence of hard to clean crevices, cavities and passageways. The holes through the deck at the locations of the depressions provide good drainage and air circulation. The foregoing and other objects, features and advantages of the present invention will become more apparent from the following description of preferred embodiments and accompanying drawings.

DESCRIPTION The invention is mostly described in terms of a pallet having the dimensions of a 40 inch by 48 inch by 5 to 6 inch high GMA pallet. The essential design of the pallet, except for the top, is in accord with the pallet described in U.S. Pat. No. 6,705,237 of Moore, the disclosure of which is hereby incorporated by reference. The invention will be useful with other pallets which have different kinds of bases and different shapes. Parts of the pallet are injection molded, and may be made with gas assistance. See U.S. Pat. No. 5,401,459. The several parts or subassemblies of the pallet may be joined as an assembly by known thermoplastic fabrication methods, for example, by mechanical means, by hot plate welding, vibratory welding, or ultrasonic welding. See, for instance, U.S. Pat. Nos. 6,250,234 and 6,283,044. The thermoplastic parts of the pallet may be made of commercial grade polypropylene, high density polyethylene (HDPE) or other polyolefin. The examples herein are described in terms of HDPE. Other plastics, including thermoset plastics and engineered plastics, may. Since the pallets and parts comprise metal reinforcing beams they may be characterized as predominately plastic. Pallet 20 is shown in FIGS. 1, 2 and 3 and in the exploded view of FIG. 4. Pallet 20 comprises a base 30, a top 90, and columns 28, 29 which extend upwardly from the base to support the top. Top 90 comprises deck 22 and frame 24. The deck comprises two thermoformed HDPE plastic sheets 44, 46 which are attached to each other, to the frame. The space between the deck sheets is filled with rigid polyurethane foam 36. The manner in which the parts of the pallet are manufactured is essential to pallet function. In particular, the elements are made variously, e.g., by injection molding, thermoforming, and foaming in place: and, they are structurally interconnected, as will be described. Frame 24 forms the periphery of the top of the pallet. By definition the frame is an open rectangle. Deck 22 spans the interior opening of the frame, and it and whatever portion of the frame is exposed comprise the pallet surface which receives goods for transporting. Deck 22 is comprised of two thermoformed plastic sheets 44, 46, which are joined to each other by welding of the sheets and by adhesion of rigid thermoset foam. Deck 22 has a multiplicity of truncated circular conical depressions 42 in its essentially planar horizontal surface; and preferably, it also has a multiplicity of elongated slot openings 74 proximate the corners and center of the pallet, to enable a worker to manually grasp the pallet. First, the non-deck elements are described in detail. The base is comprised of outer rails 31 which form a rectangle. The opposing side centers of the outer rails are connected by cross rails 33. Eight columns 28 extend upwardly from the base; and top 90 is mounted on the columns. There are two openings 34 on each side of the pallet for fork entry; they are nominally 3.2 inches high and 12 inches or more wide. Center column 29 extends upwardly from the intersection of the two cross rails 33. Deck 22 is attached to both the frame 24 of the top and to the center column. Rectangular cross section steel beams 50 run within the HDPE outer rails 31 of the base. Similar steel beams 45 run within the thermoplastic cross rails 33. The beams provide reinforcement to the base and pallet as a whole, in cooperation with the structural parts of the top. The combination of features makes the pallet suited for use in storing goods on open beam warehouse racks and in meeting certain other GMA pallet strength requirements. Beams are preferably shaped and incorporated within the base in accord with the teachings of U.S. Pat. No. 6,705,237 of Moore et al. See also the teachings of U.S. Pat. No. 6,955,128 of Apps et al. and U.S. Pat. No. 5,868,080 of Wyler et al. The disclosures of the foregoing patents are hereby incorporated by reference. The beams preferably are light steel box beams having a multiplicity of lightening perforations along their vertical edges. They are formed and shaped generally as described in U.S. Pat. No. 6,705,237. At final assembly, spaces within the rails which are in proximity of the beams, and the interiors of the beams themselves, are preferably filled with rigid foam so the beams are well captured within the molded plastic parts. See the Moore patent. Beams 50, 45 are not attached, as by welding, to each other at their intersections, although they may be in other embodiments. Preferably, the beams are constructed and positioned so that when the plastic of the rails softens as a result of the heat from a fire, the beams will be released their attachments, thus enabling the pallet to collapse due to the weight of itself and goods, which can help mitigate the rate of heat release. See the commonly assigned U.S. patent application entitled �Fire collapsible beamed pallet,� bearing Atty. No. EPC-2443 filed on Feb. 21, 2006 herewith by R. Moore et al., the disclosure of which is hereby incorporated by reference. Pallet 20 is preferably constructed by injection molding the body 70 so it comprises the frame, the hollow columns and major portions of the base rails. When the pallet is assembled, metal beams are inserted into lengthwise open cavities that are provided on the underside of the molded base rails of body. Then, cover plate 54 is the welded to the bottom of the body, to seal the cavities and the beams within the pallet, protecting them from contact with the external environment. See FIG. 3 and FIG. 4. With further reference to FIGS. 3 and 4, deck 22 is comprised of two sheets 46, 48, each having spaced apart conical depressions. The sheets are attached to each other by welding at the depression locations and at their peripheries. They are also structurally attached to each other by the rigid foam which fills the interior space of the deck. Depressions are created in the deck sheets prior to assembly by thermoforming of flat sheet of about 0.06 inch thick HDPE. That is, the sheets are heat softened and shaped within the molds of a dual wall thermoforming machine. Alternative known means of forming flat sheet may be used. In the invention, at least one of the deck sheets has a multiplicity of spaced apart conical depressions. As shown in FIG. 2, preferably both the top sheet 46 and bottom sheet 48 have depressions, respectively depressions 42 and depressions 44. The preferred depressions are truncated cones which have flat bottoms 77, 79. To assemble pallet 20, deck 22 is first fabricated by placing formed bottom sheet 48 onto a fixture. Then, metal beams 53 are placed on the sheet, so that each beam from the vicinity of diagonally opposed corners. The beams have slight bends at their center points to enable crossing each other. Then the top sheet is placed over the first sheet and welded to it, to fuse the mated flat bottoms of the depressions 42, 44 and the outer edges. Then, rigid polyurethane foam 36 is formed by chemical reaction within the space between the sheets. The foam, described in more detail below, provides support to the sheets, so the top sheet especially has good resistance to concentrated downward impact loads. The foam also provides a structural load-bearing connection between the sheets. After the deck assembly has been made, the flange 49 of the deck assembly is welded to ledge 80 of frame 24. The portion of the frame which defines ledge 80 preferably comprises a multiplicity of open cavities, bounded by transverse ribs. See FIG. 4. When the deck flange is welded to the ledge of the frame, the cavities are converted into closed cells. As needed, sealant may be applied to the joints between the flange and the frame, both around the periphery of the deck, and at the joint 57, shown in FIG. 3, which is between the underside of the deck and the frame inner edge. Known sealants of surface weld material may be used. See also the commonly owned related U.S. patent application, entitled �Plastic pallet with sealed deck to frame joint,� bearing Atty. No. 2442, filed on Feb. 21, 2006 by R. Moore, the disclosure of which is hereby incorporated by reference. In an alternate mode of fabrication, the bottom sheet may be placed within the frame of the pallet, rather than in a fixture, before placement of the beams, adding the top sheet, etc. Beams 53 of the deck 22 run in an x-pattern as shown in FIG. 2 and FIG. 4. The x-pattern deck beams cooperate with the other parts of the deck, with the frame 24, with the columns and with the rectangular pattern of rails and beams of the base, to provide good strength to the overall pallet, particularly with respect to racking. Optionally, additional beams may be added to the top of the pallet, to run around the periphery of the deck or within the frame. The deck beams generally have the same kind of construction as the beams of the base rails. While the deck is preferably set within the frame that forms the periphery of the top of the pallet, in an alternate embodiment, the deck may extend to the outer edge of the top or frame. Conversely, it may be desirable to inset the deck from the edge by a greater amount than shown in the Figures, Lengthwise impact absorbers may be placed in proximity to the outer edges of the frame, particularly within the bridge parts of the frame which span the fork lift openings 34 of the pallet. The object of such alternative is to reduce the adverse effect on the deck of horizontal impact blows on the top of the pallet. See the commonly owned patent application entitled �Plastic pallet having impact resisting plastic top� bearing Atty. No. EPC-2437 and filed on Feb. 21, 2006 by D. Swistak et al., the disclosure of which is hereby incorporated by reference. The top surface of deck 22 has a multiplicity of spaced-apart truncated conical depressions 42. They are large compared to the deck perforations which characterize the prior art. For example, the diameter of the preferred embodiment 1.8 inch diameter circular depression is greater than 3 percent of the length or width of the top. The two sheets of the deck are welded together at each depression location. As shown in FIG. 2, each depression preferably has a flat bottom 77, 79. The depth of each depression is sufficient to extend approximately half way across the space between the parallel substantially planar surfaces of the two sheets. In the assembled deck the bottom of each depression preferably has an associated hole 55, so that in the assembled deck there is means for draining of liquid and circulation of air through the deck. Holes 55 may be made in the deck sheets before or after they are joined together, by punching, drilling, and the like. Alternatively, decks may be made with no through holes. In an exemplary 40 inch�48 inch GMA pallet like that shown in FIGS. 1 and 2 the edges of the rectangular deck are inset about 2 inches from the frame outer edges. Thus the deck is about 36 inches�44 inches in dimension. An exemplary deck comprises nominally 0.06 inch thick HDPE sheet and is about one inch in total thickness. The rectangular cross section hollow metal beams 53 of the deck are made of 0.035 inch thick cold rolled AISI 1018 steel, with a height of about 0.88 inches high and a width of about 1.3 inches. In the exemplary GMA pallet configuration, adjacent depressions 42 are spaced apart center-to-center by nominally 3.5 inches and have the following nominal dimensions and features: The major or base diameter (at the deck surface) is about 1.8 inches; the minor or apex diameter (at the bottom of the depression and center plane of the deck) is about 1.3 inches. The depth of each depression is nominally 0.5 inches. The sidewalls slope at about 25 degrees to the vertical axis of the conical shape. The diameter of each hole 55 is about 0.75 inches. In an exemplary GMA pallet there are a total of 72 depressions, counting the hand-holes. Thus, there is one depression for each 20-25 square inches of deck area. In an exemplary pallet deck which includes x-pattern beams, the depressions are arranged in four essentially equilateral triangular shape arrays. Each array has a triangle base running along and centered on an edge, as the pallet is viewed looking downwardly. See FIG. 1. The triangular groups are separated from each other by areas which lack depressions, to thereby provide locations in the deck where beams 53 run. FIG. 5A through 5D are fragmentary views of decks, to show alternative embodiments of depressions. In these other Figures, elements which are analogous to those previously discussed have the same number with a suffix. In FIG. 5A, depressions 42B are only present in top sheet 46B; the bottom sheet 48B is flat. The bottom of each depression 42B comprises a flat 77B, which facilitates welding of sheet 46B to sheet 48B. FIG. 5B shows a deck having sheets with opposing depressions 42D and 44D, which had been formed as open ended truncated cones without any flat bottoms. When the sheets 46D, 48D were welded, the open conical ends of the depressions mated and formed welded joint 76. In FIG. 5C, depression 42E of sheet 46E is also made as an open truncated cone. Upon assembly, the small end of the cone passed through a previously made hole in bottom sheet 48E. The end of the cone was then swaged over, or headed, to form lip 78. The lip is then welded to the bottom sheet, to avoid any crevice. FIG. 5D shows a deck where the bottom sheet 48F only has depressions 44F. The depressions 44F extend to the elevation flat top sheet 46F. When the sheets 46F, 48F were welded a joint 52 was formed where the end of the depression 44F touches the underside of the top sheet. The construction shown in FIG. 5D is preferably used to form the hand holes 74. An exemplary hand hole is at least about one inch wide and at least 4 to 5 inches long, sufficient in dimension for a worker's fingers or hand to be inserted. Other than when the depressions form hand holes, the depressions shown in FIG. 3 are preferred, because the array of mating flat bottoms along the center plane of the deck and the stubbiness of each depression provide better strength and easier fabricability. Thus, a preferred embodiment comprises the hand holes having the configuration of FIG. 5D and other depressions having the configuration of FIG. 3. While the depressions have been described in terms of equilateral circular cones, in the generality of the invention the horizontal cross section of the depressions may be other than round, for instance, it may be rectangular or non-round. And the depressions may be asymmetric with respect to a vertical axis running through a hole or the center of the depression. When a reference is made herein to a diameter associated with a depression, for any non-circular depression that shall mean the diameter of a circular depression having the same area. The sheets of the deck may have other texturing in addition to any depressions, for instance, corrugations; and, the upper surface of the top sheet may have an anti-slip or other surface finish treatment. Obviously, when the depressions in one sheet are intended for mating with depressions in the other sheet, then the pattern or arrangement of depressions on one sheet has to mirror the pattern or arrangement on the other sheet. The depression pattern, which encompasses the number, sizing, locations, spacing of the depressions, may be varied within the invention. There are several considerations in the choice of depression parameters. They include: The depressions and associated holes ought to be sufficiently large, so that they do not become easily plugged, and so that they can be readily cleaned should debris accumulate within. A multiplicity of depressions is desirable because they strengthen the sheets of the deck as does any texturing. But if the depressions are either too large or too many in number, the result may be insufficient planar surface for supporting certain kinds of goods; and, there may be an unacceptable diminution in section modulus and resultant rigidity and strength of the deck. If there are too few depressions, then the desired draining or venting can suffer. Engineering analysis and design choice can be used to trade off the different parameters relating to depressions, according to the particular needs of the pallet user. Preferably, within the limitations of the foregoing factors, when depressions have through holes, some will be preferentially located so that any fire sprinkler water which falls onto the deck can fall onto the rails 33, 31 of the base, to help suppress burning there. See related U.S. patent application entitled �Sprinkler friendly pallet� of R. Brochu, bearing Atty. No. EPC-2440, filed on Feb. 21, 2006, the disclosure of which is hereby incorporated by reference. Particular structural foams are desirable for filling the spaces between the sheets of the deck. A preferred material is a polyurethane foam having a density of 2 to 4 pounds per cubic foot; for example, such as Elastopor polyurethane Product No. P12570R available from BASF Corporation, Wyandotte, Mich., U.S. The foam is a two-component system consisting of an isoncyanate component and a polyol blend component and is formed in place by chemical reaction. As known in the art, the interior surfaces of the top and bottom sheets, which are in contact with the foam, are preferably pre-treated by flame or electric charge devices, so there is a good bond between the sheet and the foam. At final assembly, the same rigid foam is also placed within the hollows 72 of the columns and in any spaces in the base rails, including the interiors of the beams. When the thermoset polyurethane structural foam is so placed, it can provide the pallet with additional strength and can have a favorable effect on fire test performance, such as that measured by UL 2335. The foam material constituents may be deposited into the diverse cavities of the pallet by means of access ports not shown in the Figures. After filling, the ports are preferably sealed with plugs or sealant, or by means or spin-welded plastic nubs, as described in a related U.S. patent application entitled �Pallets having multi-purpose nubs� of D. Swistak et al., bearing Atty. No. EPC-2444, filed on Feb. 21, 2006. The disclosures of both the foregoing patents are hereby incorporated by reference. The preferred rigid foam by design has relatively low shear strength compared to the other plastic parts of the pallet. Thus, during cool down after fabrication, and during thermal cycling in use, a beam may differentially thermally expand lengthwise relative to the foam and rest of the pallet, by shearing the foam which unavoidably passes through the beam perforations. See the related U.S. patent application entitled �Thermoplastic pallet having thermoset foam-filled or foam-coated structural parts� of R. Moore, bearing Atty. No. EPC-2140, filed on even date herewith. The HDPE or thermoplastic material of the pallet may comprise known commercial flame retardant, depending on requirements related need to be met, such as the fire test requirements of Underwriters Laboratories (UL) Standard 2335. Likewise, the foam may incorporate a flame retardant. FIG. 6 and FIG. 7 show an alternate embodiment pallet 20A. The pallet has a deck 22A and other features which are essentially like those which have been described in connection with pallet 20. The primary difference between pallet 20A and pallet 20 is in the way deck is constructed. In pallet 20A only the top sheet is thermoformed and the bottom sheet 44A is injection molded as an integral part of pallet body 70A. This provides certain advantages. Among them is the elimination of the joint 57 where the underside of the deck and frame meet. See FIG. 2. Another is that the sheet can be made more uniform, compared to the localized thinning which characterizes thermoformed sheets. Further, the bottom sheet may be provided with more pronounced and detailed surface features, for instance, for locating the beams. Normally, injection molding is not a very practical way of fabricating plastic sheets, owing to feeding difficulties. However, in pallet 20A, the frame and multiplicity of columns 28A, 29A which are part of the body facilitate feeding of the bottom sheet. Bottom sheet 44A comprises the both circular depressions 44A and oblong depressions 79A which provide the hand holes. When pallet 20A is assembled, beams 53A are put in place on the sheet 46A and the thermoformed top sheet 46A is welded to the ledge 80A of frame 24A and at any location where there is a depression. FIG. 8 is like FIG. 7 and shows a portion of pallet 20C. Pallet 20C illustrates an alternative injection molded body construction. Body 70C comprises open top columns 28C and base 30C. The top 90C comprises the injection molded frame 24C. The top is welded to the open tops of the outer columns 28C. The deck is not shown in the Figure, but will be attached to the ledge 80C. Alternately, the bottom sheet of the deck may be as described in connection with pallet 20A, that is integral with the frame 24C. While the invention has been described in terms of a pallet with a base, the invention may be used with pallets which have downwardly extending columns only, and on base connection the bottoms of the columns, which in such instance may be called feet. While it is preferred to have the above-described reinforcing beam patterns, e.g., the x-pattern in the deck and rectangular pattern in the base, alternative beam patterns may be used. A pallet may have fewer or no beams, although strength will be probably be inadequate for GMA pallet purposes. Fusion welding is the only presently known economic way of continuously joining mating parts. However, the term welding as used herein shall encompass the use of adhesives and chemical bonding, should strong and economic products become commercially available. The advantages of the invention have been described in the Summary and above. Although this invention has been shown and described with respect to a preferred embodiment, it will be understood by those skilled in this art that various changes in form and detail thereof may be made without departing from the spirit and scope of the claimed invention.
