Abstract: A revolver is provided with two cylinders, each of which is alignable in a firing position, a storage position, or a loading position. The cylinders are carried by a crane that pivots to orient the cylinders in a selected one of the above three positions. When one cylinder is in the firing position, the other cylinder will be in the storage position. A cartridge retaining ring secures cartridges within a cylinder as the cylinder travels from the storage position to the firing position. An ejector mechanism is provided on each cylinder to expel spent cartridges from cylinder chambers. Advantageously, the two cylinders can be loaded with two different types of ammunition.

Abstract: The airborne air cleaning station features a dirigible supporting a gigantic collector hood exteriorly mounted thereto, and an enlarged housing having a plurality of different types of air cleaning devices contained therein. The collector hood funnels polluted ambient air into an air intake system that places the on-board air cleaning devices in fluid communication with the collector hood. Sensors within the air cleaning station analyze an incoming air flow to determine the pollutants which need to be removed from the local atmosphere. Then, an automatic control system actuates automated valves of an on-board piping system to route incoming air to those air cleaning devices which are best equipped to remove whatever particular pollutants have been detected by the sensors. The inclusion of a plurality of different air cleaning devices, such as wet scrubbers, filtration machines, cyclonic spray scrubbers, etc. advantageously equips the airborne air cleaning station to deal with a wide variety of pollutants.

Abstract: The invention comprises a set of six dice that provides two groups of intransitive dice, each group containing three dice (10, 20 and 30). The dice of one group are sized larger than those of the other group. Each die is one of three colors and each group of three intransitive dice includes a die of each color. The six dice are used in a casino game wherein all dice are rolled and then twelve possible bets are resolved. These bets fall into three catagories: contests between two dice of the same size but different colors, contests between two dice of one color and two dice of another color, and contests matching two dice, each of a different color and different size versus another two dice, each of a different color and different size. Game apparatus includes a layout (40) providing twelve betting areas (A-L) and chips (50) for placing wagers on twelve possible bets.

Abstract: A fluid shutoff device for use as a safety device to cut off the water supply to a building in the event of overly high water consumption due to a leak or break in the plumbing in the building is provided with a motor that is responsive to remote actuation to rotate a three position selector valve to a desired flow setting. The selector valve is settable in a position which allows water to flow freely through the safety flow control device as if it were not there, a position which diverts water through a safety flow pathway, or a position that prevents water flow into the main water line entrance of the building, thereby allowing the invention to act as a shutoff valve. At least one optoelectronic device is included in the safety device to monitor the flow position of the selector valve by detecting the absence or presence of light reflected off a sensor drum that rotates in synchronism with the selector valve.

Abstract: A mechanical robot having hydraulically operated arms, mandible claws, neck, head and jaw, resembles a giant prehistoric reptile. It is driven from an on-board cockpit and is capable of picking up an automobile and crushing it, then biting into it with large teeth located within a powerful jaw. Various audible and visual effects are produced during operation thereby generating a frightful spectacle for exhibition, promotion and entertainment. The robot is capable of folding into a rigid structure and being attached to a trailer tractor for road hauling on its own wheels.

Abstract: A brake mechanism is provided with brake pedals that are pivotably attached to opposite sides of a cart, or the like, by hinges and mounting brackets. Each brake pedal includes a downwardly extending leg having a friction foot at a distal end thereof. The brake pedals are pivotable to a braking position whereat the friction feet are frictionally engaged with the ground, thereby anchoring the cart, or the like, in place. One or more crossbars connect the brake pedals so that the pedals pivot in unison. A crossbar is provided which engages the underside of the cart to thereby limit the pivotal travel of the brake pedals. Adjustable length crossbars are preferred so that the dimensions of the brake mechanism can be adjusted for retrofit application with various sized dollies, or the like. A quick release locking device is provided to maintain the brake pedals in the braking position as well as in a freewheeling position.

Abstract: Electronic athletic equipment is provided by installing one or more force sensors beneath selected strings loops which secure a string bed to a racquet, or the like. The string loops are selected to correspond with strings defining a target area within the string bed. When a movable game element impacts the target area, the force sensors are activated by pressure exerted thereupon by one or more stressed string loops. In response to activation of one or more force snesors, control circuitry affixed to the racquet triggers an audible signal generator, which in turn sounds an indicating signal that the target area has been struck. The present invention may be employed to produce different audible signals in response to different impact locations upon the string bed.

Abstract: An adaptor is provided with a threaded end for union with a garden hose, or the like, and a conically enlarged opposite end configured to fit about a wide variety of spigots and pipe ends. A worm gear clamp tightened about the adaptor squeezes annular ribs on the interior of the conical end into sealed engagement around a faucet spout or pipe. The conical end of the adaptor includes exterior annular ridges which position and retain an adjustable band of the clamp in alignment with an interior annular rib so that the action of the clamp is focused thereupon for an improved seal. The adaptor includes an internal reinforcement web or mesh to prevent water pressure-induced swelling of the adaptor.

Abstract: A protective cover for eyeglasses is comprised of flexible material that can be folded into a compact configuration suitable for storage within a pouch. The pouch is either integrally formed within a strap for retaining eyeglasses about one's neck or is provided with rings for attachment to the strap or portions of an eyeglass frame. The flexible material comprising a cover body of the invention is tethered by a cord to the inside of the pouch so that it cannot be lost. The flexible cover body is stretchable to envelope the lens portion of eyeglasses and includes a hem around an opening in the cover body through which eyeglasses are inserted for protection therein. This hem includes an elastic band which tends to draw the cover body snugly about the eyeglass lenses.

Abstract: A tap wrench comprising a handle portion and a chuck is provided with a joint arrangement that allows for axial misalignment of the handle portion and the chuck. The joint comprises a stem that extends from the chuck and provides four planar pins equidistantly spaced thereabout which slidably engage four slots equidistantly spaced about a central opening defined in the handle portion. The stem is retained within the central opening by the engagement of each pin in a respective slot. Oscillation of the stem within the central opening provides for the above-noted axial misalignment.

Abstract: A ventilated back support pad configured to rest atop an automobile seat is provided with a plurality of apertures on one or more of its faces. Forced air is channeled from a selected automotive air vent through the apertures via a flexible hose having one end connected with air passageways within the support pad. The opposite end of the flexible hose includes a funnel shaped attachment head adapted for releasibly engaging the selected air vent. This attachment head includes two locking pins which can be manually secured to a louver of the vent. In other preferred embodiments of the invention, the back support pad can be provided with a ventilated seat support rest integrally formed therewith and/or internally mounted electric fan. Further, as an alternative to the use of many apertures, a single enlarged aperture covered by a screen, or the like, can be utilized to allow forced air to escape from the support pad.
