  • Patent number: 5888050
    Abstract: A precision high-pressure control assembly for supercritical fluids comprises a continuous flow system having a pressure control loop which includes a source of fluid communicating with a piston driven pump. A pressure sensor monitors the pressure of the supercritical fluid in the outlet line of the pump. A pressure controller has an input for receiving a signal relating to the pressure sent by the pressure sensor and the pressure controller yields an electronic output signal to an electropneumatic regulator. A source of air communicates with the electropneumatic regulator to provide pressurized regulated driver air directed to the pump. The electropneumatic regulator controls the regulated driver air pressure of the pump in accordance with the signal received from the pressure controller. The piston head of the pump is in a cryogenic chamber to minimize flash and cavitation.

  • Patent number: 5880165
    Abstract: Modified or filled rebond polyurethane foam structures having desired plushness and compression without adversely affected tensile strength at a given density as compared to unfilled rebond polyurethane foams are formed from an admixture of shredded or chopped polyurethane foam particles and a finely divided inorganic mineral filler, such as barium sulfate or calcium carbonate or mixtures of these and like mineral fillers, that is further mixed with a substantially non-foam forming liquid prepolymer binder. A portion of the polyurethane foam particles, from about 10 to about 60 parts by weight based upon 100 parts by weight, is replaced with filler. For each 100 parts by weight of the combined foam particles and filler, about 10 to about 30 parts by weight of prepolymer is added. After the wetted admixture is compressed to the required density, the prepolymer binder is cured with heat and/or steam.

  • Patent number: RE36156
    Abstract: The invention relates to techniques for manufacturing columnar-grained polycrystalline sheets which have particular utility as substrates or wafers for solar cells. The sheet is made by applying granular silicon to a setter material which supports the granular material. The setter material and granular silicon are subjected to a thermal profile all of which promote columnar growth by melting the silicon from the top downwardly. The thermal profile sequentially creates a melt region at the top of the granular silicon and then a growth region where both liquid and a growing polycrystalline sheet layer coexist. An annealing region is created where the temperature of the grown polycrystalline silicon sheet layer is controllably reduced to effect stress relief.
