Abstract: The invention relates to an ophthalmic lens comprising the cured product of a composition comprising: 60-99 wt % of a poly(allyl carbonate) of a polyhydroxy alcohol, said polyhydroxy alcohol having from 2 to 20 carbon atoms and from 2 to 6 hydroxy groups in the molecule; 0.01-10 wt % of at least one radical initiator; 0-20 wt % of comonomers; and a cyclohexyl diallyl ester oligomer in an amount of 0.05 to 60 wt %, having the formula I wherein X denotes a divalent hydrocarbon residue derived from a diol having 2-20 carbon atoms, optionally partly replaced by a residue derived from a polyol having 3 or more carbon atoms and 3-10 hydroxy groups, and n=1-100.

Abstract: A conveyance device for receiving slaughtered animals or parts thereof at a first point and releasing slaughtered animals or parts thereof at a second point has a rotatable conveyance disc which is provided with slits along its circumference. Provision is made for a feed device for feeding the slaughtered animals or parts thereof to the conveyance disc at the first point, and for a discharge device for discharging the slaughtered animals or parts thereof from the conveyance disc at the second point. Each slit can support at least two slaughtered animals or parts thereof in a bearing manner.

Abstract: A refrigeration-coupled thermal energy storage control system includes apparatus and methodology for establishing target cooling and heating storage conditions, and selecting between cooling and heating modes, based upon outdoor temperature history, and for operating the system until the target storage conditions are achieved. In the cooling mode, cooling storage quantity increases with increases in outdoor temperature, and in the heating mode heating storage quantity increases with decreases in outdoor temperature. The system further includes apparatus and methodology for biasing operation of cooling, heating and domestic hot water production modes during off-peak periods, rather than during one-peak periods. The system incorporates logic for fan coil pump seasonal interlocking, outdoor heat exchanger fan operation, outdoor heat exchanger coil defrosting, and compressor crankcase heater operation.

Abstract: The invention relates to a three function heat pump system which provides space heating, space cooling and hot water production. The system permits hot water production all year long without operation of the system in the heating or cooling modes. The system also provides a check valve arrangement which allows passage of a refrigerant through the receiver in all three modes without reversing the flow of the refrigerant through the receiver. The valving arrangement also prevents migration of the refrigerant from the liquid receiver to a thermal storage tank during the hot water production mode. In addition, the valve arrangement allows the refrigerant to pass through throttle or expansion valves when the liquid is passing from the liquid receiver to the thermal storage tank and outdoor air coil, while bypassing the expansion valves when the refrigerant passes from the outdoor air coil and the thermal storage tank to the liquid receiver inlet.

Abstract: The invention relates to a three-function heat pump system which provides space heating, space cooling and hot water. The system permits hot water production all year long without operation of the system in the heating or cooling modes. To this end, the system employs a large storage tank and a relatively smaller hot water tank. A heat exchanger within the hot water tank is sized sufficiently to permit the hot water heat exchanger to function as a system condenser, thereby permitting the refrigerant to bypass the large storage tank. The system is packaged in a compact unit in which the compressor of the system is located within an insulated container with the domestic hot water tank. The crankcase of the compressor therefore remains warm to prevent migration of the refrigerant to the compressor during off seasons. The location of the compressor adjacent to the hot water tank eliminates the need for less energy efficient resistance crankcase heaters.

Abstract: A valve for batchwise discharging a liquid material from a container having an aperture for the passage of the material. The valve comprises a valve unit (3) which is an assembly of a valve stem 4 having two spaced collars functioning as valves. The collars are fixedly connected to the valve stem at right angles thereto. The valve stem is supported and guided at points on opposite sides of the valve area, ensuring proper centering during movement of the valve stem.
