Abstract: A fuel injector system for a combustor of a gas turbine engine includes first and second fuel injectors rendered operative to discharge fuel to the combustor during a high power regime of engine operation and rendered non-operative during a lower power regime of engine operation. The first and second fuel injectors include respective first and second fuel discharge passages in fuel flow communication to one another and to the combustor via associated fuel discharge lips to sustain a flame region. The first and second fuel injectors are operatively associated with respective first and second air discharge means having air discharge lips for discharging air to the combustor for sustaining the flame region therein. When the fuel injectors are rendered non-operative, different pneumatic pressures are established at the fuel discharge lips to purge fuel from the fuel injectors to the combustor.

Abstract: A method for forming a hidden tear seam in the cover for a safety air bag assembly comprises the steps of filling a heated open mold with liquid plastisol or dry powder comprised of polyvinyl materials; forming a gel layer of polyvinyl chloride material on the open heated thin metal mold; dumping excess polyvinyl liquid plastisol chloride material from the gel layer; fusing the gel layer; stamping a tear seam in a fused layer while it is still plastic by providing an anvil having a surface thereon of a first predetermined area and including an embossment thereon extending outwardly of said first predetermined area and stamping the tear seam by directing the embossment into the fused layer until the surface engages the fused layer and wherein the first predetermined area is sized to produce a reaction force on the anvil to determine the depth of penetration of the embossment and thereafter finally curing and cooling the fused layer and removing same from said thin metal mold.

Abstract: A method and apparatus for reclaiming urethane foam and polyvinyl chloride plastic material from composite plastic articles (18). The articles pass through a granulator (23) and pass through a first elutriator (36) where two streams of particles are formed. A denser stream passes to a second elutriator (50) where at its exit (56) substantially pure polyvinyl chloride particles are passed into bin (58). A less dense stream of particles pass to a screen separator (64) where intermediately sized particles are sorted onto conveyor (74) which passes substantially pure urethane foam to baler (76).

Abstract: Liquid leak detector apparatus and method including a fluid system having two fluid tanks which are fluid flow interconnected and which have a fluid flow-rate switch operative between the tanks for detecting the quantity of flow for establishing equilibrium between the tanks and thereby detecting the leakage of fluid in the system.

Abstract: An SIR door and instrument panel are formed by adhering a single, unitary cover material over a preformed door insert member and separate preformed panel insert member. The insert members are sprayed with an adhesive and placed on a support member with the door insert member aligned with and raised above an opening in the panel insert member. The single, unitary cover material is laid over the insert members and vacuum formed thereabout. Thereafter, the cover material is trimmed from the door insert member. The door insert member and cover material are removed from support member. The instrument panel and supplemental impact restraint (SIR) door may thereafter be assembled.

Abstract: A blind fastener designed to secure workpieces having aligned holes therein is provided. The fastener comprises an elongated stem having a head at one end and a serrated tail at the other, and a tubular sleeve having a head through which tail of the stem extends and a tail which is engaged by the head of the stem. The stem further includes a shear ring for bulbing the sleeve tail and a lock ring for locking the stem to the sleeve. The stem also has a neck which engages a reduced diameter shoulder portion in the sleeve. Interference between the neck and the shoulder causes the sleeve to expand radially outward so as to fill any clearance or gap between the sleeve and the workpieces. A reservoir located in the stem accepts excess shoulder material sheared off during the hole filling process, the excess material also serving to form a secondary lock.

Abstract: A process for producing a reinforced plastic motor vehicle bumper includes the steps of placing a woven roving (17) on a center section of a preform screen (10) that is retained by a vacuum draw from a suction fan (16).
