Abstract: A multi-disc flying device is disclosed in which outer and middle discs rotate in opposite directions by a force generated by the unwinding of a torsion spring. Downwardly extending deflecting plates on each disc generate an upward force during rotation to prolong the flight of the device. An inner disc rotatably attached to the middle disc has a normally curved rudder assembly to impart a curved flight path to the device so that it will return to its launching point. A propeller is driven by relative movement between the rudder and the inner disc to provide a propulsive force to the flying device.

Abstract: A dual action, self-cleaning windshield wiper having a pair of elongated brushes and a pair of wiper blades pivotally attached to a main blade frame. The elongated brushes are mounted on a brush mounting frame portion of supporting frames which pivot to enable a leading brush to contact and clean the windshield while at trailing brush is out of contact with the windshield. A wiper blade frame also pivots so that a leading wiper blade contacts the windshield while a trailing wiper blade contacts the trailing brush to clean the wiper blade.

Abstract: A windshield wiper is disclosed having a rotatable roller scrubber mounted on a roller retainer which is attached to the windshield wiper frame or blade. The roller retainer may have a semi-cylindrical configuration defining an internal space in which the roller scrubber is mounted. The roller scrubber has a plurality of elongated scrubbing strips and is located in the roller retainer such that one of the scrubbing strips extends outwardly of the assembly to bear against a window or windshield of the vehicle. A pair of roller retainers, each having a roller scrubber, may be attached to a single windshield wiper frame. Stops are located within the interior spaces of the roller retainers so as to enable each of the roller scrubbers to rotate in only one direction. The stops are located such that the roller scrubbers attached to a single windshield wiper frame rotate in opposite directions. Cleaning brushes extend into the internal spaces so as to clean the scrubbing strips as the roller scrubbers rotate.

Abstract: A windshield wiper includes a pair of wiper blades pivotally secured to an H-shaped connecting seat which is in turn pivotally secured to a shaft carried by a wiper arm, with the connecting seat having a pair of cleaner strips positioned outwardly of the wiper blades for cleaning the blades prior to their alternating engagement against the windshield during the back and forth movement of the wiper arm.

Abstract: A windshield wiper frame structure is disclosed in which the wiper frame structure can be folded and its length adjusted to multiple sizes. A main frame has hinged portions which enable the main frame to be compactly folded for storage and transportation. In use, links, which support a pair of wiper blades are adjustably attached to the main frame to permit adjustment of the wiper structure length. Additional adjustment may be provided by adjustably attaching blade holders to each link.

Abstract: The invention is an adjustable windscreen wiper whose length shall be freely adjustable to fit windscreen of all sizes with a compact structuring to lower manufacture cost and higher the value of wiper.

Abstract: A seal ring socket is disclosed having a ball ring at an insert end which rolls up on a socket neck portion when an insertion pipe is pushed into the ring socket. The rolling of the ball ring expands its volume to insure a water-tight seal against the insertion pipe. Grooves formed in a socket neck portion cause unbalanced stressing of the interior and exterior surfaces of the ring socket thereby assisting in the rolling of the ball ring.

Abstract: A quick pipe coupling a circular receiving chamber adjacent to the orifice thereof for holding a movable taper ring and an inflatable tube, an U-shaped lock pin releasably inserted therein to retain the taper ring in place, a toothed lock ring fastened in the orifice, wherein the movable taper ring is squeezed by said inflatable tube against the teeth on the toothed lock ring when the U-shaped lock pin is removed from the pipe coupling, causing the teeth on the toothed lock ring to respectively engage into the outer surface of the pipe inserted through the lock ring, the movable taper ring and the inflatable tube into the pipe coupling so that the pipe inserted therein is firmly retained in place.
