Abstract: 1. In the process for preparing a rocket motor, the improvement which comprises applying a layer of an uncured organic material capable of being cured to a rubbery material, to the interior combustion chamber wall of a rocket vessel, partially embedding powder grains in the exposed surface of said uncured material before solidification, thereafter curing and solidifying said uncured material, whereby a rubber-base liner is formed having one surface firmly adhering to said wall and said powder grains firmly adhering to the exposed surfaces of said liner, with a portion of each powder grain protruding from said liner, filling the lined portion of the chamber with a thermoplastic propellant charge, and solidifying said propellant charge, whereby a firmly adhering bond is formed between the solidified propellant charge, the powder grains and the solidified liner.

Abstract: 1. In combination with a vessel forming a rocket motor combustion chamber, a rubber-base liner firmly adhering to the interior chamber wall, said rubber-base liner containing between about 2.5 and 30 percent by weight of an inorganic metal salt selected from the group consisting of zinc chromate, barium chromate, zinc phosphate, lead phosphate, potassium phosphate, and mixtures thereof, and a propellant charge substantially filling the lined portion of the chamber, said propellant charge firmly adhering to said liner.

Abstract: A reticle illuminator for a reflex sight having a light gathering rod mounted in a housing which in turn is mounted on the sight barrel or housing. The rod is exposed to ambient light and emits fluorescent light to illuminate the reticle. A magnifying lens is focussed on the rod to intensify the brightness of the ambient light which strikes the rod. The rod housing has a number of component parts for easy assembly and disassembly.

Abstract: An elastomeric tip member for mounting on the piercing end of a nail-like fastener. The tip member has a forward end having means on its exterior for providing an interference fit with the wall of a hole through a bracket or the like into which the tip member is inserted. The tip member is preferably formed from a plastic material which will break up when the fastener is driven into a supporting material. The tip member thus provides an expendable temporary connection between the fastener and the bracket prior to driving the fastener into a supporting material to secure the bracket thereto.

Abstract: Shot pellets formed from finely divided powder adhered together in pellet form by a thermoplastic polymeric material decomposable in the acid environment of the digestive tract of waterfowl.

Abstract: A nitrocellulose-containing lacquer for producing a smokeless powder propellant, which lacquer includes nitrocellulose, a solvent for the nitrocellulose, water, and a surfactant for preventing the water from forming discrete globules in the lacquer.

Abstract: An inflating system of the type utilizing a propellant charge and stored fluid under pressure to inflate an inflatable member such as a vehicle safety bag. The propellant chamber in which the propellant burns is separated from the reservoir in which the fluid is stored by a nozzle member. Means is provided for reducing the throat area of the nozzle member upon actuation of the high or fast deployment of the system to increase the burning rate of the propellant charge.

Abstract: A ski boot of the rear or modified top entry variety which has a rear part hingedly connected to the remainder of the boot. The rear part is pivoted away from the remainder of the boot to permit the wearer to put the boot on or take it off. The hinge is in the form of a laterally extending T-shaped mating slot and flange combination. The stem of the flange is flexible and helps to accommodate the pivotal movement.

Abstract: A method of treating karaya gum to stabilize it so that it is less sensitive to the presence of certain priming compositions and will exhibit, when used with priming compositions, improved extrusion characteristics and rheological stability. The karaya gum is suspended in an anhydrous alcohol and treated with a reagent which is soluble in the alcohol whereby the gum renders a priming composition suitable for extrusion for mechanically charging primers.

Abstract: A system for introducing caseless propellant pellets into a firing chamber of an apparatus deriving power from such pellets. The system includes a guide for holding a supply of pellets in a refillable container, and a pusher acting on the pellets to selectively deliver one thereof to the firing chamber.

Abstract: A means for providing an indication of the length of the bolt member of an anchor bolt assembly of the type including a bolt member and an expandable sleeve member. The end of the bolt member opposite the sleeve expanding portion thereof is provided with a recess, the depth of which is reversely proportional of the length of the bolt member.

Abstract: A device for stopping a runaway ski from sliding down a hill after a skier has fallen and the ski has been released from the skier's foot. Provision is made so that the ski will not be released from the skier's foot in a static drop situation, such as where the ski accidentally comes loose from the skier's foot while the skier is riding on a lift, but will be released in a dynamic release situation, such as where the skier falls while skiing.

Abstract: An adjustable base suitable for mounting an optical sight on a firearm. The base contains spring-biased windage and elevation adjustments and a provision for locking the base in place to assure location accuracy and to absorb the firearm recoil.

Abstract: A shell deflector-catcher which can be removably mounted on the receiver of a firearm adjacent to the shell ejection port therein. The device is provided with tabs which engage walls of the receiver and a springy finger which lies adjacent to the ejection port and contacts spent shells ejected therefrom to deflect the shells downwardly toward the ground. The spring finger may be fitted with a removable cap which enlarges the dimensions of the finger to enable it to cooperate with one side wall of the ejection port to catch ejected shells and prevent them from falling to the ground.

Abstract: A diaphragm and valve assembly using the same for controlling fluid flow from a pressurized source of fluid. The diaphragm is longitudinally perforated at a peripheral area to permit axial flow of the fluid past the diaphragm, and is radially perforated to provide ambient atmospheric pressure on the downstream side of the diaphragm. The valve assembly is of the type which regulates fluid flow in response to pressure changes occurring at the fluid source which pressure changes result from ambient temperature changes thus establishing a preset fluid flow rate which persists throughout a wide range of ambient temperatures.

Abstract: A telescopic sight for use on a firearm, which sight provides an eye relief of greater than about 3.0 inches and an exit pupil of greater than about 25 mm. so that the target as viewed through the scope will substantially fill the eyepiece. The scope reduces the necessity of close alignment of the viewer's eye with the optical axis of the scope, thus enabling the viewer to quickly pick up the target with the scope and fire.

Abstract: A self-contained propellant gas generating cartridge for use in connection with safety systems utilizing inflatable confinements. The cartridge has a tubular body portion housing a propellant charge, a head portion at one end of the body portion in which is mounted an ignitor for the propellant charge, and a nozzle member closing the other end of the body portion. In one embodiment the tubular body and head portion may be metallic while in another embodiment they may be plastic. The cartridge may also include means to reduce the effective throat area of the nozzle when a fast deployment of the system is desired.
