Abstract: A system for supplying hydrogen to an apparatus which utilizes hydrogen contains a metal hydride hydrogen supply component and a microcavity hydrogen storage hydrogen supply component which in tandem supply hydrogen for the apparatus. The metal hydride hydrogen supply component includes a first storage tank filled with a composition which is capable of forming a metal hydride of such a nature that the hydride will release hydrogen when heated but will absorb hydrogen when cooled. This first storage tank is equipped with a heat exchanger for both adding heat to and extracting heat from the composition to regulate the absorption/deabsorption of hydrogen from the composition. The microcavity hydrogen storage hydrogen supply component includes a second tank containing the microcavity hydrogen supply. The microcavity hydrogen storage contains hydrogen held under high pressure within individual microcavities. The hydrogen is released from the microcavities by heating the cavities.

Abstract: A resistor capable of being used as an RC network can be constructed using an electrically conductive metal sheet coated with a dielectric coating serving as a substrate. The dielectric coating supports two separate resistor terminals and a resistance element extending between these terminals. A third terminal is provided for use in connecting the metal sheet to one of the resistor terminals so that the resistor may be used as an RC network.

Abstract: A toy vehicle has a first and a second surface which are spaced apart from one another and reversibly serve as the top and bottom of a vehicle. When one of the surfaces is serving as the top of the vehicle the opposite surface of the vehicle is serving as the bottom of the vehicle. The vehicle includes wheel members which are capable of supporting the vehicle over a support surface no matter which of the surfaces of the vehicle is serving as the top or the bottom. Also incorporated in the vehicle is an inverting mechanism which alternately inverts the vehicle such that the surface serving as the top of the vehicle after inverting serves as the bottom of the vehicle and the surface serving as the bottom of the vehicle after inverting serves as the top of the vehicle.

Abstract: A game of the type having a housing including a playing surface, an object launcher located in one end of the playing surface and a magnetic target member located on the other end of the playing surface is improved by including a plurality of ferromagnetic objects being independently capable of being propelled by the object launcher toward the magnetic target member. Each of the objects is capable of being attracted to and magnetically held by the magnetic target member except when another of said objects has already been attracted to and is being held by the magnetic target member then the first of said objects which is magnetically held by the target member is made magnetic by the target member and in turn serves as the target for the next of said objects to be launched by the launching member. Subsequent objects launched by the launching member are launched then toward the first of the objects already captured by the magnetic target member.

Abstract: A sighting device completely devoid of any lenses for use in pistol target shooting has a one-piece elongated outer tube having at least one saddle integrally formed on the outer tube and located proximal to one of the ends of said main tube. The saddle has two holes in it passing through the saddle into the interior of the main tube which provide access into the interior of the main tube. The holes are placed on the saddle 90 degrees apart from each other. Located on the saddle over each of the holes is a turret member. A portion of each of the turret members passes through each of the holes into the interior of the main tube. Mounted within the interior of the main tube is at least one elongated inner tube. The inner tube is pivotally mounted within the main tube such that one of its ends is free to move within the interior of the main tube.

Abstract: In a pinball-type game having a playing surface over which an object is propelled and an object feed and propulsion apparatus for propelling the object across the playing surface includes: a housing associated with said surface and an actuator member mounted on the housing. The actuator is capable of moving from a rest position to an actuated position and back again. When an object is located next to an object contact surface on the end of the actuator and the actuator moves from the actuated position back to the rest position the object is propelled across the playing surface.Mounted in the housing associated with the actuator is an object feed mechanism which is capable of simultaneously moving the object from a first position adjacent to the feed mechanism to a second position locating the object in an abutting relationship with the contact surface on the actuator as the actuator moves to its actuated position. To accomplish this the actuator is operatively connected to the feed mechanism.

Abstract: Structures which are considered to be primarily useful as toys can be constructed utilizing members or arms adjustably mounted on a rotating shaft within the body of such a structure. By shifting the positions of such members or arms the type of movement of such a structure on a supporting surface can be varied. If desired, adjacent of such structures may be connected through the use of flexible couplings such as suction cups.

Abstract: A bathtub of the type having a bottom and four sides is improved by providing a smooth continuous, horizontally extending planar surface extending outwardly from the top of the four sides. A skirt member extends downwardly from this planar surface for a short distance. Located within the skirt member is a retaining member which is capable of retaining an apron panel in a fixed alignment with the tub such that the apron panel is interchangeable with the left and right sides of the tub allowing the tub to be used interchangeably in installations which previously required either a right or left handed tub. Extending along the longitudinal axis of the bottom of the tub is a runner retaining member to which is attached one or more runners which suspend the tub above a supporting surface allowing both drain and inlet pipes to be located between the supporting surface and the tub.

Abstract: A game of skill has a support housing on which there are located a plurality of independent object transfer mechanisms preferably no two which are identical. The transfer mechanisms are aligned in a sequence such that a pathway includes a plurality of discontinuities along its length which divides it into a plurality of segments. Each of the transfer mechanisms includes one segment of the pathway and some of the transfer mechanisms can also include more than one segment. This creates a discontinuity in the pathway between each of the transfer mechanisms as well as between each segment when more than one segment is found on one transfer mechanism. Each of the transfer mechanisms includes a movable portion which is moved by the operator of the game via a control mechanism attached thereto. By manipulating the control mechanisms a spherical object can be caused to travel across the pathway.
