Abstract: A hinge with two elongated flexible flange portions which can be fastened to an article by sewing or stapling. Each flange portion includes a plurality of integral aligned knuckles which engageably cooperate with the knuckles in the other whereby a pin can be passed through the knuckles of each flange portion forming an elongated hinge.

Abstract: A simulated knock off wheel spinner nut which can be attached to a wheel without having to remove the wheel from the vehicle. The simulated nut is sized to be partially inserted into the hub opening of the wheel and then locked in position by a plurality of rigid tabs located about the inner circumference of the spinner nut and maintained in place by set screws with their heads accessible from the outer circumference of the nut. By tightening these screws, each tab is drawn tightly against the inside wall of the hub securing the nut to the wheel.

Abstract: A microscope slide for cytological analysis of the type where it is extremely important that the presence of a small number of cancer cells present in a smear be detected. A plurality of spaced parallel lines are permanently placed on the slide with the space between each successive pair of lines defining a reference plane. The spacing between each pair of lines corresponds to the field of view produced by the particular microscope lens and eyepiece being utilized so that when a viewer makes a viewing pass across each successive reference plane that the smear is located in, by keeping the lines continuously in the field of view during each pass, the entire area of the smear will be viewed.

Abstract: A cage type enclosure for small animals, such as guinea pigs, hamsters, gerbils, rats of the like which simulates the appearance and operation of an apparatus such as a vehicle having revolving and reciprocating members. The simulated apparatus includes a wheel rotated by the movement of the animal which reciprocates another component of the apparatus through interconnecting linkage. Rotation of the wheel may also simulate other features of the apparatus, such as other wheels, a bell, etc. Access is provided to the enclosure for feeding and watering the confined animals.

Abstract: A one-step wire-wheel sealing system for pneumatic spoke wheels is disclosed in which a hot-melt adhesive is applied in molten form to the dropped spoke well of a metal wheel rim and is then cooled in place to form an adherent, resilient annular ring which prevents rotation of the spoke fasteners and leakage of inflation gas between the spoke ends and the spoke holes in the rim.

Abstract: A simulated knock off wheel spinner nut and adapter for attaching the nut to a wheel without having to remove the wheel from the vehicle. The adapter is sized to be inserted into the hub opening of the wheel and then locked in position by tightening a plurality of outwardly extending set screws located about the circumference of the adapter into the inside wall of the hub opening. The adapter is further provided with threads to receive the simulated spinner nut.

Abstract: An exercise apparatus which assists a person in assuming a shoulder stand or a hanging from the knee position and accomodates either of these positions. The apparatus includes a frame with two side panels between which are mounted a pivot bar, a shoulder support and a knee support bar. To assume either the shoulder stand or hanging from the knees position, the user faces the pivot bar and pivots about it at the midsection of the body. The spacial relationship between the pivot bar, shoulder support and knee support bar permit the user to slowly and carefully pivot into the shoulder stand position utilizing the knee support bar if desired to assist in maintaining the shoulder stand position or to hang free from the knees. When the exercises are completed, the pivot bar supports the user in returning to an upright position.

Abstract: A perpetual calendar which has transparent letters and numbers positioned in a predetermined matrix arrangement on an opaque sheet. Within the predetermined matrix arrangement of numbers and letters are abbreviations for the name of each day of the week, each month of the year, and the numerals one through thirty-one. Small pieces of opaque material which will adhere to the sheet are sized to overlie any abbreviation of the name of the days of the week, any abbreviation for the months of the year, and any numerals between one and thirty-one within the matrix so that any calendar date can be readily indicated on the calendar by adhering the pieces of opaque material to the rear of the transparent letters and numerals within the matrix defining the particular month and name of day abbreviations and the day of the month.

Abstract: A self powered carriage which receives a conventional hydraulic floor jack to enable a disabled and immobile automobile to be moved and selectively manuvered. The carriage receives a conventional hydraulic floor jack in a manner whereby the load bearing wheels of the jack are elevated and immobilized and in their place, a pair of independently controlled powered wheels on the carriage are utilized which, once an immobilized vehicle is elevated by the jack, the vehicle can be moved in a desired direction by selectively operating the powered wheels.
