Abstract: A normally horizontal base section supports the side section of a frame in upright position. A top section of the frame is normally positioned horizontally and has an open interior through which the lip of a bag can be inserted. The bag lip is wrapped downward over the outer periphery of the top section whereupon a rigid clamping ring is inserted over the top section to hold the bag lip in position. After filling of the bag, the clamping ring is removed, thereby releasing the lip of the bag for removal and, if desired, insertion of a new bag. When not in use, the base and top sections of the frame can be swung relative to the side section so as to extend parallel thereto for compact storage.

Abstract: A motorcycle carrier is conformed to extend on an incline from the back of a vehicle in its first position and to articulate to a vertical alignment at the back of the vehicle in its second position. This articulation is achieved by translating one end of a motorcycle supporting track within a vertically aligned channel, the track being linked to the other end of the channel by a pivotal link having a length selected to define the foregoing articulation. The ends of the track may include pivotal segments between which the wheels of the motorcycle may be clamped.

Abstract: A method and structure is disclosed herein for effecting repairs of ballistic damage in stressed aircraft structures, including bending of two thin manually deformable metal sheets each adhesively bonded to one part of a hook and pile fastening material, known as "Velcro", the bent and conformed patches once in place being impregnated with resin. Once the resin hardens the interlocked hook and pile surfaces are fixed, fixing the curvature and stiffness of the resulting patch.

Abstract: An enclosure generally shaped to simulate the appearance of a flight vehicle is provided with a seat facing a video display and is supported on a parabolic dish for freedom of angular motion in the pitch and roll modes. Included in the enclosure may be a weighted control stick which, according to its angular displacement, displaces the effective center of gravity, thus moving the enclosure in the pitch and roll modes. A set of orthogonal resolvers deployed in the enclosure and pendulum articulated provide binary signals of the pitch and roll angles achieved to the video display, simulating the flight vehicle attitude while a program is cycled through a microprocessor and superposed onto the pitch and roll inputs to generate on the video screen images simulating flight.

Abstract: A method for repairing ballistic impact damage to structural panels of vehicles comprising the steps of cutting out the damaged area in the panel in a preselected size circular cutout, bending a circular patch including an exterior circular metal sheet laminated to a smaller circular interior cloth layer to match the surface convolutions of the panel, impregnating the interior cloth layer with resin and attaching the patch to the panel. In this manner the patch is bent to fit before impregnation and is fixed to the bent shape by fixing the cloth layer.

Abstract: This invention relates to certain novel articles formed from polypropylene compositions, and more particularly to articles produced by forming polypropylene compositions into a predetermined configuration and plating with a coating of one or more metals. The novel plated articles prepared from polypropylene compositions of the present invention exhibit greatly improved bonding between the metal coating and the polypropylene surface. The polypropylene composition contains a polyhydroxy aromatic compound and a resinous material. The composition may optionally contain a nucleating agent.

Abstract: A frequency doubler circuit uses a single capacitor which is initially charged. A pair of switches is sequentially actuated so that each switch acts to first discharge the capacitor and then charge it in the opposite polarity. The switches are sequentially actuated from a differential input amplifier. Thus each input cycle will actuate both switches so as to discharge and charge the capacitor twice. Output logic senses the capacitor cycling and produces two output pulses for each input cycle.

Abstract: The luggage case has a pair of wheels located at a lower back edge such that when the case rests on a flat surface, the wheels are held spaced from the floor surface. On lifting the case side opposite that including the wheels, the wheels are brought into rolling contact with the floor. A handle assembly is foldably received into the side wall opposite that including the wheels and can be selectively folded outwardly into a position for pulling or pushing, or, when not in use, folded into a receiving recess formed in the case side wall. A spring-loaded latch mechanism secures the handle within the recess during nonuse, and a finger release enables selective extension of the handle outwardly from the case wall for easy access when it is desired to move the case.
