Abstract: A sealing gasket for an automotive air filter comprising an annular member which includes a base portion and a seal portion. The base portion is of harder durometer than the seal portion whereby the seal portion can more readily adapt to the contour of a contact surface which it may engage so as to provide a better seal between the sealing gasket and the contact surface. In a preferred form of the invention, the seal portion comprises an annular projecting part having a lower durometer than the base portion, said lower durometer being on the order of 25 Shore A.

Abstract: A universal connector for selectively coupling a windshield wiper blade holder with the end of a windshield wiper arm of either the bayonet mounting type or the hook mounting type. The universal connector comprises a unitary molded body having a pair of spaced apart side members for straddling a central portion of the wiper blade holder and including a hollow coupler portion to receive the bayonet arm end. First complementary means are provided for detachably securing the bayonet arm end within the coupler portion of the body. The body also includes a contoured exterior surface adapted to receive the hook type arm and second complementary means for detachably securing the hook type arm to the body.

Abstract: A double braided hollow rope assembly and method for making same wherein the rope consists of an inner hollow braided rope core and an outer braided rope jacket. The braid on the side of the outer jacket is opened and through that opening, a loop of the inner rope is pulled. A retaining ring with barbs formed thereon to engage the braids of the outer jacket is placed on the end of the rope to be spliced or formed into a loop or eye. The braid on the side of the inner core which has been pulled through the opening in the outer jacket is opened. The end of the rope with a retaining ring around it is inserted into the opening in the side of the hollow core of the inner rope. The outer jacket is then worked backwards until it once more covers the inner loop with the end of the rope with the retaining ring now contained within the hollow longitudinal central opening of the inner core.

Abstract: A reflector for bicycles, motorcycles or the like vehicles, which includes a body having a reflective surface and a rear support housing secured thereto. The rear support housing has a major bore and a minor bore co-axially formed therewith. A bolt extends axially through the two co-axially formed bores. One of the bores, which is non-circular, is adapted to receive a complementary non-circular portion of the bolt. The bolt has a threaded portion extending rearwardly from the rear support housing. The rear support housing includes an annular wall which defines at least a part of the major bore and a cap is secured to the annular wall, for example, by ultrasonic welding, so as to retain the bolt in desired position in the bores.

Abstract: This invention embodies a side reflector assembly adapted to be mounted on the spokes of a bicycle wheel or the like, such assembly including two slim elongated bodies bonded together. Each body has a front reflective surface comprised of at least a first planar surface and a second roof-like surface having two inclined planar sections symmetrical to the longitudinal axis of the assembly. Bolt and nut means are provided for clamping the assembly onto the wheel spokes.

Abstract: A hose coupling for hoses handling relatively high fluid pressures, which hose coupling embodies a cup-shaped body having primary and secondary internal grooves in a wall defining a chamber, and a tubular pressure element having a deformable externally grooved end portion at one end, an intermediate externally tapered portion, and a collapsible end portion. The deformable grooved end portion is adapted to squeeze material into the primary grooves. The collapsible end portion is adapted to squeeze material into the secondary grooves so as to enhance the securement and sealing of the hose relative to the hose coupling. Ball means movable axially within the hose coupling are adapted to cause axial movement of the tubular pressure element so as to initially collapse the collapsible end portion thereof and subsequently, to deform the deformable grooved end portion.

Abstract: An improved foldable golf cart seat assembly is disclosed which includes a horizontally disposed seat frame that is attached to the main golf bag carrying frame assembly and that encircles the golf bag. A seat member is pivotably attached to the seat frame and has a foldable leg assembly that is attached to its undersurface and that may be arranged so as to support the seat member in a generally horizontal position when the seat member is in use. When not in use, the seat member may be moved to a generally vertical position and the leg assembly may be folded so that it is out of the way and adjacent to the undersurface of the seat member.

Abstract: A spoke-mounted reflector assembly for a bicycle or like vehicle comprised of a pair of side reflectors having cooperating interengaging convex and concave portions for securing the two side reflectors to one another in desired position on the spokes of a bicycle.

Abstract: This invention relates to a system for generating power utilizing the elevation differences and available temperatures on the earth's surface, such as occurs in a mountainous region with a nearby valley or desert. The system includes heat rejection means, as for example, a condenser located at a higher elevation (a mountain top). Means for supplying heat to the system may be provided at a lower elevation (in a valley or desert region below). A geothermal source of heat, such as a hot spring, may be used. Power generation means are also provided in the valley and operatively communicated with the condenser on the mountain top and the heat supply means in the valley. Liquid flowing from the condenser to the power generation means at a relatively high pressure will drive the power generation means to create electrical energy and the liquid will be expanded, vaporized and cooled. The cooled vapor will absorb heat from the heat supply means and then be returned to the condenser on the mountain top.

Abstract: A lock assembly useful in coupling a tire assembly to a wheel which is locked and unlocked by a magnetic key.

Abstract: This invention relates to an environment control system utilizing the elevation differences and available temperatures on the earth's surface, such as occur in a mountainous region with a nearby valley or a desert. The system includes heat rejection means, as for example, a condenser located at a higher elevation (a mountain top). Means for supplying heat to the system may be provided at a lower elevation (in a valley or desert region below). A geothermal source of heat, such as a hot spring, may be used. Liquid flowing from the condenser at a relatively high pressure will be expanded, vaporized and cooled. The cooled vapor will absorb heat from the heat supply means and then be returned to the condenser on the mountain top.The heat supply means or heat exchanger in the valley may be utilized as an evaporator to provide cooling for a buildingn, as for example, a hotel or factory.

Abstract: A method is disclosed for controlling the operation of a two speed electrical motor used to drive a hermetic refrigerant compressor so as to attain an overall motor compressor efficiency at low speed operation which is equal to or greater than the overall motor compressor efficiency at high speed operation.
