Abstract: Disclosed herein is a reciprocal drive for a hand powered vehicle including a first axle, connected to a propulsion lever that the occupant of the vehicle pushes and pulls in a rowing motion, a first and a second power gear mounted on the first axle, wherein the first and second power gears rotate in opposing directions when the user pushes and pulls the propulsion lever, a first and a second drive belt, wherein the first drive belt delivers propulsive force from the first power gear to a gear wheel when the user pushes the propulsion lever and the second drive belt delivers propulsive force from the second power gear to the gear wheel when the user pulls the propulsion lever, and a second axle, on which the gear wheel is mounted, which rotates a drive wheel of the vehicle.

Abstract: Disclosed herein is a scooter-type vehicle comprising at least one front wheel and at least two rear wheels, wherein power for forward motion is developed by the occupant of the vehicle pushing and pulling a propulsion lever, which also serves as the steering mechanism for the vehicle, in both directions. A novel inventive gearbox mechanism is contained in a small housing, which allows for the drive wheel, through the steering means, to be rotated fully 180 degrees, allowing backward motion of the vehicle as well.

Abstract: An apparatus that is used to convert an ordinary table or table-like surface into a card table, that can later be removed, stowed and easily transported. In its preferred embodiment, the device would be comprised of four major components: a thin flat piece of padding; a piece of cloth with a constricting perimeter; a long, soft, flexible border; and a strap with a joining mechanism. The device would be installed onto a table by laying the piece of padding flat on the table surface; covering the padding with the cloth; wrapping the border around the common edges of the cloth, padding and table; and securing the padding, cloth and border in place around the perimeter of the table surface edge through tension afforded by the strap, with the ends of the strap being connected by the joining mechanism.

Abstract: Apparatus and methods for locating underground obstructions are disclosed. One embodiment of the present invention comprises an elongate probe with a first and second end and a first internal fluid passageway, a handle disposed on the elongate member, and a tip disposed on an end of the elongate member, wherein the tip comprises a second internal fluid passageway in fluid communication with the first internal passageway, and a flexible hose connection disposed on the elongate member, wherein the connection is disposed between the first end and the second end and the connection is in fluid communication with the first internal passageway.

Abstract: A luggage container which conveniently converts for use as wheeled suitcase, a backpack and a hand-carry bag having a first and second compartment for storage of belongings. A pair of wheels are rotatably mounted to an axle which is at an edge along the bottom of the first compartment. A pair of shoulder straps are provided in the second compartment and are concealed by a cover. When the container is used as a backpack, the cover is opened to reveal the shoulder straps. The cover is wrapped over the wheels and secured to the bottom side of the first compartment. In this manner the traveler and the traveler's belongings are protected when cartage is on the traveler's back from filth that accumulates on the wheels.
