 large scale flake ice producing machine which comprises one or more upright refrigerated discs rotatable on a horizontal shaft. Water or other congealable liquid is applied to both surfaces of the disc and frozen into sheets of ice as the disc rotates. Thereafter, the sheets are removed from disc in ice flakes. Each disc is approximately 1.8 m in diameter and comprises a pair of large round aluminium plates spaced apart about 20 mm and sealed at their periphery to form an enclosed space. Baffles are placed within the interior of the space to form rudimentary passages through which a coolant is pumped in order to refrigerate the disc surfaces.
However, the flake ice producing machine of U.S. Pat. No. 3,863,462 possesses several inherent disadvantages, including:
(a) Due to the large flow passages inside the disc, it is necessary to use a non-evaporative coolant such as brine or glycol. That is, a "boiling" or evaporative refrigerant which cools by direct expansion is not suitable for use in the disc of U.S. Pat. No. 3,863,462. Brine and glycol have low cooling capacity and large amounts of such coolants must be pumped through the disc in order to achieve the required cooling. PA1 (b) Since a coolant such as brine or glycol must be used, a separate refrigeration plant is required in order to chill the brine or glycol. PA1 (c) The discs are difficult to manufacture according to the tolerances required. The 1.8 m diameter discs must be cast and machined, and welded at their periphery, yet the flat outer surfaces of the discs must not vary from the plane in which they rotate by more than 1/8 mm.
For the foregoing reasons, the ice making machine of U.S. Pat. No. 3,863,462 is not considered to be commercially acceptable.
It is an object of the present invention to overcome or ameliorate at least some of the abovedescribed disadvantages of the prior art by providing an improved ice making machine.
It is another object of the present invention to provide an improved refrigerated disc for use with the ice making machine. The present invention relates to a transmission control apparatus for an automatic transmission of a vehicle, and more particularly to a control apparatus for a continuously variable transmission (CVT) suitable for a vehicle which can accelerate comfortably based on the driver""s intention or the running state of the
