Abstract: The present invention relates to methods and systems for purifying gases, such as for example semiconductor process gases. The invention more particularly relates to fluid purification methods and systems having improved heat transfer capabilities and controls such that the purified fluid produced from the process contains reduced impurity levels and/or exhibits more uniform concentrations within the final product. In another aspect of the invention, the activation time for adsorbent beds used in such processes and systems can be reduced.

Abstract: A powertrain includes a variable ratio transmission device (having an input shaft coupled to an engine and an output shaft coupled to a driven unit, a three-way power split transmission device including three input/output couplings, a first of which is coupled to a flywheel and a second of which is coupled to an electrical machine. The third input/output coupling of the three way power split transmission device is mechanically coupled to the engine and to the input shaft of the variable ratio transmission device.

Abstract: The invention concerns an engine cooling system that comprises a cooling circuit (8) and an evaporative cooling arrangement (9). The cooling circuit (8) has a cooling capacity provided by exchanging the heat generated by the engine with ambient air. The evaporative cooling arrangement (9) has a cooling capacity provided by dissipating the heat generated by the engine, by vaporization of a vaporizing coolant in a boiler. The cooling capacity of the evaporative cooling arrangement (9) is such that with the cooling capacity of the cooling circuit (8), the global capacity of the cooling system can match, at least peak, cooling demands. As the cooling capacity of the cooling system is divided between the capacity of the cooling circuit and the capacity of the evaporative cooling arrangement, the capacity of the cooling circuit can be reduced in comparison to a conventional cooling circuit which has to match alone peak cooling demands.

Abstract: A cooling circuit for the thermal engine of an automotive vehicle includes a main loop that includes a first exchanger for collecting the heat from a first heat source, a first radiator and a pump connected in series by ducts for the circulation of a cooling liquid, the temperature of the cooling liquid being kept under normal operation conditions at a temperature lower than or equal to a predetermined threshold value. The cooling circuit includes a first bypass of the main loop in parallel relative to said first radiator, the first bypass including sequentially, in the circulation direction of the cooling liquid, a second exchanger for collecting the heat from a second heat source and a second radiator connected in series by ducts for the circulation of the cooling liquid, the temperature of said cooling liquid at the outlet of said second exchanger being set, under normal operation conditions, at a temperature higher than or equal to the predetermined threshold value.

Abstract: A prefabricated multi-layer roofing panel is utilized in a roofing system for low-slope roofs. The prefabricated roofing panel includes: an insulation layer that may have a self-adhering means on its bottom major surface for securing the roofing panel to a roofing substrate; a cover board that overlies and is bonded to the insulation layer, and a waterproofing membrane that overlies and is bonded to the cover board. The waterproofing membrane may have waterproofing membrane overlaps for overlapping and being bonded to the waterproofing membranes of other roofing panels in the formation of a roofing system. Preferably, the insulation layer includes interlocking structure for interlocking the prefabricated multi-layer roofing panels together in the roofing system.

Abstract: An air conditioning system operates on a supercritical cycle for a vehicle and includes a circuit through which a refrigerant flows, which circuit includes an evaporator where the refrigerant collects heat from the ventilation air to be conditioned, a compressor, a cooler where the refrigerant releases heat into the outside air, an expander, and an arrangement for humidifying the outside air that contacts the cooler. The system has no internal heat exchanger.

Abstract: Self-adhering flashing cap strip and end lap connector cap sheet assemblies include a reinforcing layer encapsulated within self-adhering bitumen. The bottom major surfaces of the flashing cap strips and the connector end lap cap sheets are formed by the self-adhering bitumen and the top major surfaces of the flashing cap strips and the connector end lap cap sheets have lateral edge portions formed by the self-adhering bitumen and a coated central portion that extends between the lateral edge portions. The flashing cap strips are used to interconnect cap sheets at roof surface intersections in the formation of waterproof roofing layers and the connector end lap sheets are used to connect lengths of cap sheets at the job site.

Abstract: An apparatus and method for performing single-instruction multiple-data instructions using a single multiply-accumulate unit while minimizing operational latency. The multiply-accumulate unit generates a first half and a second half of a data result. A register stores the first half of the data result. A miscellaneous-logic unit determines when to release the first half of the data result from the register to synchronize the first half and the second half of the data result.

Abstract: Circuitry for scanning and observing domino CMOS logic or other logic gates. Master and slave stages includes circuitry for latching a bit into the master stage through pulsing of a clock signal and subsequently latching the bit into the slave stage through pulsing of another clock signal. The number of transistors required for scanning is minimized by using existing latch structures within the logic.
