Abstract: A process for making an elastomeric laminated product including the steps of laminating an elastomeric film between a first spunbond nonvowen layer and a second spunbond nonwoven layer so as to form a laminated web, transporting the laminated web through intermeshing rollers so as to strain portions of the laminated web to form activated regions in the laminated web, and transporting the activated laminated web to a first portion of a rotating wheel, the first portion of the wheel having a cross direction width that is smaller than a cross direction width at a second portion of the wheel, so that the laminated web follows rotation of the wheel and is stretched in the cross direction at the second portion of the wheel before separating from the wheel at the first portion in a relaxed state.

Abstract: A dual stage inflator is disclosed in the present invention. The dual stage inflator comprises a diffuser subassembly and a gas generator subassembly. Also disclosed is a multiple stage inflator, which comprises a diffuser subassembly, a first gas generator subassembly, and a second gas generator subassembly. Both the dual stage inflator and the multiple stage inflator have numerous output characteristics or output profiles associated therewith to protect different size and position vehicle occupants. The dual stage inflator and the multiple stage inflator release either stored gas or stored gas mixed with combustion gaseous products from the burning of gas generant.

Abstract: A dual stage invention is designed to autoignite an autoignition material before a low temperature gas generant melts. Low temperature gas generants include a high nitrogen content organic fuel with ammonium nitrate as the oxidizer. The dual stage inflator has a first gas generant and a second gas generant that are ignited by separate igniters. The first gas generant and the second gas generant are insulated from the inflator housing to delay the heat transfer from the housing to the first gas generant and second gas generant during a bonfire test, which needs to be passed to receive Department of Transportation classification. The dual stage inflator also has an autoignition cartridge for disposing of the second gas generant by the first gas generant after the first gas generant burns for a predetermined amount of time.

Abstract: A low onset dual stage hybrid inflator comprising a diffuser subassembly, a gas generator subassembly, and a pressure vessel. The dual stage inflator offers a variety of different output levels of inflation gas. The four main deployment scenarios for the dual stage inflator are primary output, staged output, full output, and secondary only. For primary output, only the stored gas is released from the inflator. For staged output, the stored gas is released and after a short period of time (i.e. 30 ms), the gas generant is ignited. For the full output, the stored gas is released from the dual stage inflator at the same time the gas generant is ignited. For secondary output, only the gas generant subassembly is fired, and the hot gases from the gas generant subassembly mix with the stored gas. The combination of the hot gas and the stored gas has sufficient pressure to rupture the burst disk.

Abstract: A cold gas inflator has a pressure vessel made of first and second cylindrical members that are joined by friction welding, the friction welding producing curls that serve to preclude an orifice plate from sliding into the second cylindrical member. The cold gas inflator is filled with stored gas. The cold gas inflator has a burst disk, which prevents the stored gas from exiting the pressure vessel. In the event of an automobile accident, an opening device is actuated, which causes the ignition of pyrotechnic material. This ignition generates a shockwave of sufficient energy to rupture a burst disk. The stored gas flows from the cold gas inflator in a radial direction.

Abstract: An apparatus for regenerating a catalyst absorber after contact with a combustion exhaust which consist of a pair of cooperating louvered doors one on each side of a bed of catalyst absorber, there being at least two beds such that closing a cooperating pair of louvers, isolates the bed contained between the louvers from the exhaust gases while the other bed is left with the louvers open to continue treating the exhaust gas. Between each pair of louvers and associated with the catalyst absorber bed between the respective pair of louvers, there are positioned a regeneration inlet nozzle and a used regeneration gas outlet. By selectively closing various pairs of the louvers, a portion of the bed can be regenerated while the remainder of the bed continues to treat the exhaust gases. In this way an equivalent amount of active or regenerated catalyst absorber is in contact with the combustion exhaust gases to maintain a specified outlet pollution concentration limit.

Abstract: A flue gas conditioning system generates sulfur trioxide which is injected into boiler flue gas to condition it by reducing the resistance of the particulate matter entrained in the flue gas. The conditioned flue gas is passed through an electrostatic precipitator which collects the particulate matter by electrostatic precipitation. The sulfur trioxide concentration in the flue gas is measured with a mass spectrometer downstream of where the sulfur trioxide was injected into the flue gas and upstream of the electrostatic precipitator. The concentration of the sulfur trioxide in the flue gas is measured with a mass spectrometer at a point where the injected sulfur trioxide has uniformly mixed with the flue gas. The measured sulfur trioxide concentration is used to control the flue gas conditioning system, such as by comparing the measured concentration to a desired concentration range and adjusting the amount of sulfur trioxide being injected into the flue gas accordingly.

Abstract: A method of decreasing the level of NOx, CO and SO.sub.2 emissions in a gas turbine is disclosed. A catalyst absorber, preferably made of alumina/platinum/carbonate salt, is used to oxidize the pollutant oxides and absorb them. The catalyst absorber can then be regenerated and reused. An apparatus for treating the stack gases and a method of making the catalyst absorber are also described.
