* Chemical Vapour Deposition (CVD). This was a major development area at Fulmer. A wide range of metals and inorganic compounds were deposited.  Examples are: tungsten coating of graphite rocket nozzles for ablation resistance, boron nitride crucibles for melting gallium arsenide, alumina coatings on carbon fibres for reinforcement of aluminium, zinc sulphide infrared radomes for heat-seeking missiles. Fulmers profound understanding of subhalide disproportionation led its chemists to devise a process in which halide vapour, pulsed at low partial pressure could be used to put uniform oxidation resistant coatings of aluminium or chromium on gas turbine blades. This was especially difficult because the coated surface had to include the insides of the blades long narrow cooling passages –  2mm diameter and 180 mm long for example. In 1975 Fulmer hosted the fifth International Conference on Chemical Vapor Deposition.
* The Fulmer tension meter is a device for measuring the tension in ropes and cables. A fixed length of cable is displaced at right angles using a lever and cam. The tension in the cable is arrived at by measuring the consequent displacement in the frame of the meter.  In 1971 Fulmer set up a joint company with the sponsor of this development and subsequently acquired all the shares. The meter continues to be produced and marketed by a successor company.
* Fulmer devised the RPD system for project planning under uncertainty and gave about a hundred training seminars to R&D investigators in the UK and abroad.
* The Fulmer Materials Optimizer (FMO).  This was an information system designed to enable a rapid comparison of materials competing for any given application. Many of Fulmer's technical staff contributed information to the FMO and many clients subscribed to support its preparation.  It was published in 1974 as four loose-leaf large format files. The FMO included many data sheets, nomograms and other charts. It illustrates the approach needed in 1974, before the days of hypertext and the World Wide Web.
* Ion Engine. In the early 1970s Fulmer participated in a collaborative programme on the development of ion thrusters for space propulsion. They constructed a Type T4A mercury ion thruster and a high-vacuum test facility.  Grid life testing totalling over 2000 hours was successfully completed.
* In 1975 Fulmer obtained a two-year contract from UNIDO to set up a Metals Advisory Service (MAS) in Lahore Pakistan.  The laboratories established then are now the Technical Service Centre of the Pakistan Standards and Quality Control Authority (PSQCA).
* Solar water-heating trials.  In 1976 Fulmer built a solar laboratory on the Stoke Poges site.  This was the approximate size and shape of a two-storey domestic dwelling and was mounted on a circular track so that it could be rotated to any orientation. Solar hot-water panels were mounted on the roof.  Investigations determined the economical viability of various systems for space and water heating and which materials and processes should be used.
* The development of frame-to-hull bonding methods in GRP ships.  The project enabled the construction of  for the Royal Navy, (Wilton was a prototype coastal minesweeper/minehunter and the first warship in the world to be constructed from glass-reinforced plastic) and supported the development of the Royal Navy's Hunt class Mine countermeasures vessels.
* Shape Memory alloys. When an object made of a shape-memory alloy is deformed under suitable conditions it can be made to return to its original shape by heating. Researchers at Fulmer discovered that this phenomenon is not confined to intermetallic compounds such as NiTi, but is exhibited in many metal solid solutions also. They did extensive work on many alloy systems. Two example applications developed at Fulmer are: heat-shrinkabe sleeves for use as pipe couplings and an actuator for the deployment of solar panels on spacecraft.
* Starting in 1977 YRL undertook small scale synthesis of specified organic chemicals many of them the organo-fluorine compounds widely used in pharmaceutical research and as precursors in drug manufacture. This was successful and in 1988 a joint venture with Shell Chemicals UK was launched as Yarsley Fluorochemicals Ltd.  This was later purchased by Shell. After a management buy-out, it now continues as JRD Fluorochemicals Ltd.
* Superdart. A marksman training system in which the point of impact of a rifle round on a target is computed by triangulation from the signals received from a number of acoustic sensors and is then displayed on a screen next to the firing point.  This gives the marksman instant feedback on his accuracy.  This is an example of a multi-disciplinary project.  It involved ballistics, sensor technology and mathematical modelling as well as the development of new materials.
* Acoustic emission monitoring.
* Hydrophilic polymers for soft contact lenses. YTEC devised novel homopolymer and copolymer systems for soft contact lens preparations. A polymer system was formulated to exhibit a high degree of water containment in the swollen state and yet be sufficiently stable to form a precision lens to an individual prescription. YTEC developed a process to full production scale and commissioned the production facility on the client's premises.
* Body Armour.
* Fabrication of targets for the ISIS neutron source at the Rutherford-Appleton Laboratory. These consisted of an assembly of depleted uranium discs clad in zircalloy. The production process involved machining the uranium discs, sealing their zircalloy containers by electron-beam welding, hot isostatic pressing to develop a diffusion bond between the zircalloy and the uranium and then ultrasonic testing to verify the integrity of the bond before final assembly.
* Fulmer devised techniques for probabilistic mathematical modelling and in 1986 hosted the first international conference on Modelling under Uncertainty.
