Abstract: A solar powered toy has a plurality of legs each with angularly related sections connected together. Certain of the sections are mounted for relative turning movement, and electric motors powered by solar cells are mounted to turn adjacent sections of the legs, so that movements of the legs of the device change the degree of exposure of the solar cells to the light source.
Abstract: An aligning assembly for use in dentistry, particularly in prosthodontics and/or orthodontics includes two plates each of which is to be positioned in the oral cavity of a patient at the upper jaw and to the lower jaw, respectively. One of the plates has a projection which, subsequent to an initial positioning of the plates in the oral cavity, and while the patient moves the lower jaw relative to the upper jaw, provides a centering mark on the other plate. At least the other plate is of an inexpensive, easily deformable material so that, upon removal of the jaw plates from the oral cavity, a recess can be provided in the place of the centering mark on the other plate. When the two plates are repositioned in the oral cavity to be connected to each other to form the assembly, the projection is partially received in the recess and fixes the plates with respect to each other against misalignment while they are being connected.
Abstract: The present invention relates to clockwork motors for toy vehicles of the type wherein depressing of the vehicle toward a rolling surface engages winding pinions which wind the propulsion spring as the vehicle is rolled against the supporting surface. The spring is housed in a casing to which one end is attached and the casing drives the wheel axle through one gear train. The other end of the spring is attached to a hub journaled in the casing and the spring can be wound by rotation of the hub which is accomplished by said winding pinions when engaged with a gear on the axle.

Abstract: Disclosed is a shield assembly for a catheter particularly useful for the protection of flow directed catheters used in the measurement of central venous pressure and pulmonary wedge pressure. The shield assembly includes front and rear hubs sized to permit movement of the catheter therethrough and a feed tube for interconnecting the front and rear hubs. A flexible sheath interconnects the two hubs. The sheath is substantially longer than the feed tube and is collapsible to permit interconnection of the hubs by the feed tube and is extendible to shield a substantial length of catheter.
Abstract: A manipulatable structure that contains a series of linked units. Each unit contains a plurality of rhombic-shaped panels that are hinged along their oblique edges to create a collapsible enclosure that can be used to create two dimensional patterns when the panels are folded into one of two available common planes or any number of three dimensional structures when positioned between the two common planes. Each unit, in turn, is hinged to an adjacent unit along abutting oblique corners to create a chain that can be symmetrically formed by linking the units in a repeating linear pattern or asymmetrically formed by linking the units in a random fashion.
Abstract: A sheet of electroluminescent material in the shape of an alphanumeric character is embedded in a rigid base. An exciter unit for transforming incoming electric power to the appropriate voltage and frequency for driving the luminescent material is also embedded in the base behind the character. Each character, base and exciter unit thus form a self-contained display module. A universal interconnecting member is used to electrically and mechanically interconnect the module to any other module with the proper horizontal or vertical spacing. The gap between adjacent display modules may be filled with either a cover or an electrically active header which contains such devices as an electric eye for applying power to the modules after dark or a rechargable battery charged by either an external power supply or an internal solar cell.
