Abstract: A wheeled vehicle comprises a frame having a steerable front wheel having an axle affixed to a front portion of said frame, and a hub rear wheel having an axle affixed to a rear portion of said frame. A unitary power module is used as a propulsion system, which includes a target sprocket and a mounting frame, with the target sprocket comprising a disk shaped assembly having an center opening to allow the unitary member to be placed about the wheel axle. The target sprocket mates to the hub (or axle) of either of the wheels to enable target sprocket to be concentrically attached to the wheel by engagement with the wheel by securing elements. The mounting frame may be aligned with and rotatably attached to the target sprocket to allow for aligned rotation of the target sprocket about the wheel axle.

Abstract: A wheelie scooter which utilizes an auxiliary wheel assembly mounted aft of the rear wheel of the scooter with the rear wheel in a first position. The auxiliary wheel assembly is adjustable to vary the distance of the auxiliary wheel of the auxiliary wheel assembly from the surface on which the scooter is being operated to thereby provide different levels of skill to riders of the scooter when performing of a stunt maneuver known as a wheelie. The rear wheel of the scooter can be adjusted to a second position where the scooter operates as a normal scooter and not as a wheelie scooter.

Abstract: An electric bicycle comprises a frame having a rider seat and propulsion controls positioned and thereon, a settable front wheel having an axle affixed to a front portion of said frame, and a hub spoke rear wheel having an axle with a woven spoke pattern affixed to a rear portion of said frame. A unitary power module, which may be a "kit" for use with a standard bicycle, is used as a propulsion system which includes a battery affixed to said bicycle, and an electric motor having a pinion sprocket affixed thereon. The electric motor is suitable to be connected to the battery by a battery cable. The unitary power module includes a target sprocket and a mounting frame, with the target sprocket comprising a disk shaped assembly having an center opening to allow the unitary member to be placed about the wheel axle. The target sprocket mates to the wheel pattern of either of the wheels to enable target sprocket to be concentrically attached to the wheel by engagement with the wheel by securing elements.

Abstract: A power assist apparatus which includes a battery pack that connects with a motor housing with the battery pack being removably mounted on the frame of the bicycle and the motor housing being mounted on a mounting plate which is carried by one of the support wheels of the bicycle. The power assist apparatus is designed to not only assist in the manual operation of the bicycle but also as a sole source of power for the bicycle. The mounting plate is to be affixed to the frame of the bicycle upon the desired location being selected for the mounting plate. The motor assembly operates a drive gear, pulley or sprocket which connects to a driven gear, pulley or sprocket which is mounted in conjunction with one of the support wheels of the bicycle. The motor housing may be disconnectable from the mounting plate as also the battery pack is capable of being disengaged from the frame of the bicycle permitting the bicycle to be used as a conventional bicycle without the power assist apparatus.

Abstract: A power assist apparatus, which includes a battery powered motor mounted on a manually operated vehicle, such as a bicycle, and is to be selectively usable by the rider of the bicycle to not only assist in the manual operation of the bicycle, but also conceivably as a sole source of operation of the bicycle. The power assist apparatus is fixedly mounted on the bicycle and is carried with the bicycle at all times. The power assist apparatus includes a motor assembly which is operated through a gear connection to drive a driven gear mounted in conjunction with a wheel of the bicycle. The rotational axis of the shaft of the motor is parallel to the rotational axis of the wheel.

Abstract: A power assist apparatus which includes a battery powered motor which is mounted on a manually operated vehicle such as a bicycle, which is to be selectively usable by the rider of the bicycle to not only assist in the manual operation of the bicycle but can be used as a sole source of operation of the bicycle. The power assist apparatus is normally fixedly mounted on the bicycle and is carried with that bicycle at all times. The power assist apparatus includes a housing and exteriorly mounted on that housing is a handle. Movement of the handle to various positions locates the power assist apparatus in either a disengaged position relative to a support wheel of the bicycle or to an engaged position relative to the support wheel of the bicycle.

Abstract: A power assist apparatus is to be mounted in a straddling position about the rear wheel of a bicycle. The power assist apparatus includes a housing with this housing to be mounted on a support bracket assembly which is fixedly mounted on the frame of the bicycle. The support bracket assembly includes pins which are to connect with the housing of the power assist apparatus. The latching assembly is to connect between the frame of the bicycle and the housing of the power assist apparatus with this latching assembly to be movable between a latched position and an unlatched position.

Abstract: A webbed swimming aid formed from two planar sheets shaped to conform generally to the shape of an outspread hand from a first sheet of elastic, mesh material and a second sheet of thin, stiff, water impermeable material. Truncated finger stalls are provided by stitching or sealing regions along the upper edge of the sheets towards the palm portion of the aid. Webbing edge of second sheet, or, alternatively, may be sealed within the triangular webbed regions sewn or sealed along the upper edge of the aid with apices of the triangles directed towards the palm portion of the aid to define the finger stalls.

Abstract: A screen of foraminous material is laid directly on the surface of shallow water beds where weed growth is likely or is occurring. The screen is non-reactive to the surrounding water and creates a physical semi-barrier to rootlet and stem formation and to the transmission of light to the area therebetween to thereby retard germination and growth of weeds but not to stop growth entirely. The screen is formed with sufficient openings so that the normal movement of the surrounding water is not materially affected.
