Abstract: A large surface shaped structure having a smooth surface is formed by compression molding a charge (26) of reinforced molding material containing a thermoplastic material by placing a heated mold charge (26) in a mold (12, 14) which has its peripheral surfaces spaced apart to provide a shear gap (34). The width of the shear gap (34) is adjusted to accept a quantity of molding material sufficient to dissipate residual energy in the flow front of the charge to prevent rebound of the flow front as the structure solidifies.

Abstract: A process is provided for preparing recyclable reinforced composite structures having enhanced surface appearance by heating a self-supporting porous batt comprised of an intimate homogenous blend of high modulus reinforcing fibers and thermoplastic resin fibers to a temperature sufficient to melt the resin component and convert the batt into moldable form, placing the moldable batt into a heated mold to flow, solidify and substantially crystallize the component, introducing a thermosetting resin-containing coating material into the mold adjacent at least one surface of the crystallized structure to provide a coating on the one surface and dwelling the coated structure in the mold for a time sufficient to set the coating material.

Abstract: A temperature compensator for use on a gas pressure regulator which inflates an infatable aircraft slide. The temperature compensator is cooperative with a movable valve upon actuation, to control the flow of pressurized fluid past a discharge orifice. The temperature compensator has a plurality of nested tubes that have alternate ones of a different linear coefficient of thermal expansion to provide an expansion and contraction of the overall length of the tubes to effect an adjustment of the movable valve and its corresponding control of the opening of the discharge orifice.

Abstract: A pressure regulator for use in regulating the pressure of inflating an inflatable member from a high pressure source wherein a valve housing has one end attached to a pressure source and the other end attached to a trigger mechanism. A spool valve is slidably biased into contact with the trigger mechanism which in the locked condition retains the spool valve in an inoperative condition and prevents the flow of fluid from the pressure source to inflate the inflatable member. Upon actuation of the trigger mechanism the spool valve is first unseated from its inoperative condition by a first spring and thence placed into a pressure regulating condition by a second spring in opposition to the escaping fluid pressure acting on annular face of the spool valve.

Abstract: An improved inflatable over-the-wing evacuation slide. The slide is provided with an inflatable wing ramp section projecting from the foot of the wing exit door to a point on the aircraft wing remote from the door. The wing ramp section also includes a generally flat upper or walkway surface and a lower face surface projecting in a tapered contact with the sloping aircraft wing. It also includes a pair of inflatable guard rails attached to the side margins of the inflatable wing ramp. The wing ramp then includes a right angle turn remote from the exit door and continues to terminate in an extended section proceeding from the wing to the ground. A unique support system is provided on the underside of the central portion of the extended ramp consisting of inflatable portions shaped to provide support to the slide regardless of the position of the trailing edges of the wing flaps.

Abstract: An inflatable escape slide having an inflatable platform that provide a horizontal walkway from an elevated vehicle such as a train. An inflatable slide portion is connected to the platform and is deployable in a longitudinal direction that is in the same general direction as the train thus ensuring deployment where clearance space to either side of the elevated train is limited. The escape slide and platform are an integral unit.

Abstract: A delayed restraint releaseable device utilized to restrain and controllably release the lower end of an inflating escape slide at a predetermined pressure, orientation and time. The device combines two distinct restraint mechanisms into one combination unit. The primary release is accomplished by means of shear pin or pins located at the first end of the device. Under normal conditions, the release is accomplished by shearing of the pin or pins under the load provided by the tied back inflating slide. The back-up release, in series with the primary release, occurs when the pressure of the reduced load causes a piston within the restraint to move against both a spring and captive fluid. As the piston moves, the fluid transfers through a precise sized orifice in the piston, from one side of the piston to the other. The piston moves eventually to a point at which the interlocking leg of the piston support shaft is released, thus allowing the ends of the mechanism to separate.

Abstract: A packboard fixture device consisting of a support cradle, aluminum vacuum caps, pressure block and cargo strap assembly. The support cradle is an aluminum structure with a base, side supports, and two vertical end walls, the shorter of which is hinged to allow installation and removal of the packboard with collapsed slide. The vacuum caps are preferably aluminum with rubber sealing lips which are pushed onto the pump heads mounted in the packboard. These seal off the pumps and allow a vacuum to be established within the fabric slide to evacuate all air within the slide to be folded. A thick wooden member functions to uniformly compress the deflated slide into the packboard. It acts as a pressure block to distribute the compressive forces uniformly over the hinged mechanism as it is drawn down by straps using a rachet type device for drawing the straps in tension.

Abstract: A valve having a valve housing for mounting on a high pressure fluid container. A cartridge is mounted in a fluid conduit in the valve housing leading to the fluid container. A metallic disc is crushed by the cartridge against a valve seat in the conduit to provide a reliable lasting seal. Opening of the valve is provided by releasing a trigger pin connected to a latch in the cartridge for removing a support from a portion of the disc permitting it to rupture under the high pressure and communicating the high pressure gas to a pressure regulator chamber in cross configuration with the valve conduit in the valve housing. A pressure regulator member in the chamber controls the size of a discharge orifice for lowering the pressure and introducing the gas into an inflatable body. Filling of the high pressure fluid container may be done by introducing high pressure fluid into the regulator for passage into the fluid conduit of the valve with the cartridge carrying the disc spaced from the valve seat.

Abstract: An escape slide and life raft assembly for evacuating personnel from an aircraft or other elevated place and thereafter providing a floating support when the evacuation is on water. A slide portion of the assembly has side tubes connected to transverse and longitudinal tubes of an outrigger portion to provide additional seating capacity of the assembly when used as a life raft. Upon inflation and extension of the slide portion, the outrigger portion is reefed or held in against the side tubes and only partially inflated so that the partially inflated longitudinal tubes reinforce the side tubes of the slide portion. When the outrigger portion is fully inflated and extended by releasing the reefing, the pressure in the assembly will be reduced due to the increased volume of the inflatable support tubes; however, the reduced pressure is at a preferred level for operation of the assembly as a life raft.
