Abstract: Liquids in general, and paint in particular, can be evenly distributed by a paint transfer drum having a friction-creating surface that is placed in contact with a friction-receiving surface of an endless belt that is driven (by the drum as it rotates) into and out of a container for the liquid. A scraper removes a portion of the lifted liquid from the endless belt. The scraped liquid falls upon a liquid distribution device that serves to evenly distribute said liquid laterally so that it will be evenly applied along the exterior surface of the paint transfer drum.

Abstract: An apparatus secures ventilation cloth to a screen frame. A screen frame is oriented in an approximately vertical position. The screen frame has a plurality of segments. Each segment has a mounting surface on a face thereof. At least one of said segments has adhesive on the mounting surface thereof. A ventilation cloth is hung across the mounting surface of said one segment. The adhesive in said one of the segments is melted. The ventilation cloth is inserted in the adhesive across a length of said one of the segments.

Abstract: A board game incorporating various gambling methods is disclosed. A player uses either a card game similar to blackjack or a slot machine to determine the number of spaces to be moved along a segmented path, the particular game being selected by the instructions contained in the segment on which the player landed on the prior move. Each segment also contains further instructions, some of those instructions designating a further gambling apparatus and giving odds. These further apparatuses are a roulette game or a dice game, and the player landing on that segment may gamble at these games at the designated odds. Other players can join in the gambling when the roulette game and the dice game are played. The objective of the game is for a player to avoid penalties designated on the game board, acquire a majority of the playing chips until either all of the other players become "busted" or the casino bank becomes "busted".

Abstract: Production of electrically conductive polypyrrole of enhanced stability by treating a liquid pyrrole with a solution of a strong oxidant, capable of oxidizing pyrrole to a pyrrole polymer, and oxidizing the pyrrole by such strong oxidant in the presence of a relatively large organic dopant anion, and precipitating a conductive polypyrrole. The strong oxidant, e.g., Fe.sup.3+ ion, and dopant anion, which can be an alkyl or aryl sulfonate, e.g., methylbenzenesulfonate, or a perfluorinated carboxylate, e.g., trifluoroacetate, anion, can be derived from a single compound, e.g., ##STR1## the anion serving as dopant for the polypyrrole.

Abstract: An improvement to a rotating blade is disclosed in a device that will apply variable moment forces to wind blades which are counter to the variable forces normally encountered in typical wind blades. The device consists of a gyro attached to the rotating blade and because of the torque force obtained by gyroscopic precession, the device will provide moment forces counter to normal blade wind forces. This invention shows a unique arrangement where the gyro is attached to the blade by a gyro positioner which adjusts the gyro's precessional rate. The gyro's precessional rate is varied with the blade's deflection or blade stress so that the gyro will impose a moment force counter to the cyclic deflection in the blade. Thus the device prevents or reduces the vibrational deflection and resultant stresses in the blades and its associated structures.

Abstract: A crimping tool comprising a top plate, a parallel bottom plate, a rigid arm disposed between the plates and being affixed thereto, a movable arm positioned adjacent the rigid arm and having one end thereof pivotally mounted to the plates adjacent one end of the rigid arm, the rigid arm and the movable arm being positioned and formed so that their free ends comprise opposed crimping jaws for allowing the positioning of a portion of a circle clamp therebetween when the arms are in an open position, the top plate having a sufficient width so as to rest atop the open jaws of a bench vise when the crimping jaws are fully opened, the bottom plate having a width no greater than the combined widths of the arms in order to allow the jaws of the bench vise to close against the arms, a spring for holding the crimping jaws open for facilitating the positioning of a portion of a circle clamp therebetween, and an alignment bolt for holding the crimping tool within the jaws of the bench vise whereby the crimping jaws exten

Abstract: The present invention is a dog lavatory that is installable in a basement, apartment bathroom, or a separate area of a residential home or building. The lavatory comprises a hollow, box-shaped platform having a shield mounted around the top thereof. An endless belt extends across the top of the platform and is moveably mounted for receiving animal wastes and transferring them upon movement to the internal portions of the platform. The internal portions of the platform include a drain and built-in trap area. Piping connectable to the residential plumbing conducts liquid therefrom into a perforated service pipe mounted along the top and bottom portions of the shield.

Abstract: There is disclosed a bidet seat housing in which are front and rear water jet nozzles and director members through which to pass water one or the other of the nozzles via a solenoid-operated diverter valve connected to the outlet fitting on top of an elongated horizontal water tank adjacent one end thereof, such tank having its inlet fitting on top adjacent the other end connected to a water supply line via a solenoid-operated pressure regulator. An external mode selector effects operation of one of either one of the solenoids or of a warm air blower for supplying warm air blower at the rear of the seat. The water tank contains a heater and a sensor with a temperature sensitive resistor. A control module has circuitry of which the sensor resistor is a part, and effects operation of the heater as needed to maintain water flowing through the tank at the desired temperature.

Abstract: An electric fluid heater includes a metallic container defining a heating chamber provided with a pair electrodes for passing electric current through the fluid for heating the fluid. The container has a fluid input port, a fluid output port and a safety port all communicating with the heating chamber. The ports have a reduced aperture portion of a substantial length to increase the resistance of the current leakage path from the electrodes to external ground connections. All surfaces of the metallic container including the fluid contacting surfaces of the heating chamber and ports are covered by an electrically insulative coating. An external pressure relief valve is connected to the safety port.
