In addition, certain of the parts can be used independently for other exercises.

Abstract: A locker handle assembly having a recessed mounting receptacle with a bolt mounted thereon for sliding reciprocal movement. The bolt includes a front bar, and a back bar which is connected at one end to one end of the front bar, and at its other end to a point midway between the ends of the front bar. A non-moveable door pull is connected to a sidewall of the mounting receptacle and provides a safe means for opening the locker door and prevents the ability of a combination padlock from being manipulated, while locked, so that the locker can be opened, but still allows access to the back of the padlock for use of a key thereon.

Abstract: A foldable table is disclosed that comprises three basic parts (a table top assembly, a bench assembly, and four leg assemblies) interactively coupled to form a sturdy table that is easily folded or unfolded. The leg assemblies are spring biased to swing out to the unfolded position and the bench assembly rests on the leg assemblies by the engagement of bench stops on the bench assembly with notches on the leg assemblies. The table is securable in either the folded or unfolded position so that the legs will not unfold when in the folded position unless securing means are released and so that the table will remain fixed in the unfolded position unless securing means are released.

Abstract: This invention relates to a purified wool fat essentially free from low molecular weight volatile acids, water soluble aliphatic alcohols and water. This purified wool fat is produced by effecting the esterification of free alcohols and fatty acid contained in the wool fat followed by solvent extraction and chromatographical purification of the extracted solvent. The purified wool fat can be used as a lubricant enhancer in lubricating oils.

Abstract: A seat, as may be used on a bicycle, providing improved efficiency and comfort for a rider. The seat comprises a split seat having two halves simultaneously rotatable about the longitudinal axis of a mounting post. The points of the two halves that are furthest from the mounting post are also movable up or down in conjunction with the up and down movements of the rider's legs. In addition, support portions of each half are pivotable about the longitudinal axis of the axle on which the support portions are mounted. A seat configured in this manner will rotate about the longitudinal axis of the mounting post, thus causing the right and left sides of the axle on which the support portions sit to move equal distances in opposite directions of each other, i.e., when the left side is forward, the right side will be rearward by an equal distance.

Abstract: Polyolefin polymeric packaging film is provided with a structure varying across its thickness from monolithic to porous with a density gradient ranging from .rho. to (1/2 to 1/4).rho., where .rho. is the density of monolithic polyolefin. The packaging film is characterized by a varying structure across its thickness. Such a film possesses the functions of a multi-layer film, but has none of the disadvantages of the latter associated with different adhesion of the layers, possible delamination in the course of storage and use, as well as the complex manufacturing process of a multi-layer film. The gradual transition of the porous structure of polyolefin to the poreless one from one surface of the film to another ensures distribution of liquid-phase specific additives along the film thickness.

Abstract: An educational game that aids in the development of the fundamentals of freehand drawing and assists players of the game in learning the relationship between all of the parts that comprise a whole. According to the present invention, there is provided a drawing area, such as a sheet of paper, erasable form board, etc., having imprinted thereon a single image which, when combined with several other images drawn by a player, results in a fully completed picture. In conjunction with the drawing area, a die or other selectiion device is used to determine each players' opportunity to complete the picture. Each side of the die presents the player with a different option for proceeding.

Abstract: The protection of cartilaginous surfaces against wear by ensuring their low friction despite a deficiency of joint lubrication components. A specific mixture of liquid-crystal cholesterol ester derivatives can be introduced by a variety of means into the affected joints to provide a superior lubrication of the cartilaginous surfaces.

Abstract: Disclosed is a helically wound core of ferrous material used as a differential current sensor core in the ground fault sensor of a ground fault interrupter circuit. The ferrous material comprises a single strand of wire which is wound in helical fashion to create a tubular shaped core comprising a series of wire loops (all part of the single strand) parallel to each other and running the length of the tubular shape. The core is placed around a pair of current carrying lines to be monitored for ground faults (one line leading to and one line leading away from the power source) to interact with the magnetic fields of the lines. Toroidally wound leads wrapped around the wire core act as a secondary and are connected to a ground fault interruption circuit to shut off the power to the conducting lines in the event that the sensor detects a difference in current in the lines.

Abstract: A coating is provided to a substrate in a vacuum chamber having an electric arc evaporator to form an ion-plasma comprising accelerated ions and neutral atoms of evaporated metal. The substrate contained in the vacuum chamber is provided with a negative voltage bias such that the ion-plasma is drawn to the substrate and deposited on its surface to provide the coating. A pulsed negative voltage bias is maintained on the substrate such that the substrate temperature can be maintained within the range of zero to 200.degree. C.

Abstract: A safe, practical, and less costly method for disposing of infectious personal care waste, as well as pathological waste and equipment which can be configured for large municipal type use employing continuous process techniques, or for smaller, batch type, stand-alone processors for individual sites such as hospitals.

Abstract: A method and material for the protection of construction materials against the thermal effects of fire comprising an ablative layer coated on the fire-exposed surface with an intumescent paint.

Abstract: A screw pump is disclosed in which a screw portion of the pump is constructed having an eccentric portion e, wherein the pitch S of the screw is equal to 4e. The screw channel depth h, is equal to 2e (twice the eccentricity). The resulting screw has an optimum geometric shape allowing maximum pumping capability to be achieved.
