Abstract: A bushing and sealing ring assembly including a sealing ring and a bushing. The sealing ring has a cylindrical base with an external thread and a reduced diameter, upstanding cylindrical sleeve extending co-axially from one end of the base with a predetermined height, an upper outer edge and an upper inner edge. The base and the sleeve are provided with a circular central aperture for receiving and retaining a first cylindrical member. The bushing has a cylindrical depending sidewall with an internal thread and a circular central aperture for receiving the sealing ring and a second cylindrical member and a top plate extending transversely partially inwardly into the central aperture to sealingly receive the upper outer edge of the sealing ring and having a predetermined thickness.

Abstract: A method of making an interface for adapting a photographic system for a specific format to a camera back for a different film format, in particular from a 3¼×4¼ format photographic system to a 4×5 format film back. The interface may be a modified CB 103 film magazine. An adaptor for changing a 3¼×4¼ format photographic system to a 4×5 film format or a different size film format, comprising the modified CB 103 interface and a 4×5 or different size connecting frame, wherein the total thickness of the CB 103 interface and the connecting frame is at least ⅜ inch. A different size format camera utilizing the body shell of a 3¼a×4¼ format camera and the adaptor. In particular, a method of making a coupled range finder/parallax camera that utilizes components from Polaroid Models 110, 110A, 110B, 120, 900 and 150 cameras and the adaptor.

Abstract: The glittering ink of the present invention contacts scaly glittering particles, a water-soluble resin, a water-soluble organic solvent, colorant and water. The said scaly glittering particles have a median diameter of at least 10 &mgr;m, a ratio of smoothness on the particle surface to a median diameter of not greater than 0.011, and a surface coating ratio of the said colorant in a written mark of not greater than 80% in a state of a dried written mark. In addition, the aqueous glittering ink of the present invention has the thixotropy index (T.I. value) of not less than 1.3, represented by the ratio of V0.5 to V1.0 (V0.5/V1.0), wherein V0.5 is the viscosity with the rotation speed of 0.5 rpm and V1.0 is the viscosity with the rotation speed of 1.0 rpm when the ink is measured by an ELD-typed viscometer (3° R14 cone, at the temperature of 20° C.) and the ink has the V0.5, the viscosity with the rotation speed of 0.5 rpm, of 1000˜15000 mPa·s.

Abstract: A brush tip for a motorized toothbrush has a first brush head and a second brush head. The second brush head encircles the first brush head. A shaft has two cranks, each engaging one of the brush heads. Continuous same-direction rotation of the shaft causes the brush heads to counter-rotate about a common axis. Distal ends of the first set of bristles on the first brush head form a circular pattern and the distal ends of the second set of bristles on the second brush head form an elliptical pattern.

Abstract: The glittering ink composition of the present invention contains a glass flake pigment, a water-soluble resin, a water-soluble organic solvent and water as essential ingredients. The content of the glass flake pigment is 0.01-40% by weight relative to the total amount of the ink composition. Moreover, the ink composition contains a synthetic resin emulsion as a binder component for fixing the glass flake pigment to a handwriting or a coated film in 0.01-40% by weight in solids relative to the total amount of the ink composition. The synthetic resin emulsion has an anionic property or a nonionic property and its minimum film forming temperature is not higher than 20° C.

Abstract: A prosthesis in the form of a cage having opposed complimentary bearing surface assemblies. The bearing surface assemblies moveable towards and away from each other. The moving mechanism being part of the bearing surface assemblies. Each of the bearing surface assemblies having an outer bearing surface whereby movement of one bearing surface assembly in one direction will move the bearing surface assemblies away from each other and movement in the opposite direction will move the bearing surface assemblies towards each other.

Abstract: The object of the present invention is to provide a double-color ink which is capable of producing a double-color effect stably for a long period of time. The present invention relates to a double-color ink comprising (1) metal powder pigments, (2) water, (3) at least one water-soluble organic solvent selected from the group consisting of alcohols, glycols and glycol ethers having a branched hydrophobic group(s) and (4) at least one water-soluble dye selected from the group consisting of anthraquinone dyes, carbonium dyes and metal complex dyes; and a writing utensil using the same as an ink.

Abstract: The invention provides a water-based metallic ink composition comprising a metallic powder pigment and a solvent characterized by its further comprising a polyvinyl alcohol. This composition provides a record consisting of a central line derived from a formulated colorant or the color of the writing substrate and contour lines derived from the metallic powder pigment and bordering on both sides of the central line.

Abstract: An electronic musical device having a keyboard actuated by random liquid drops. The device includes a base, a synthesizer, a keyboard having a plurality of keys pivotably attached to the base to actuate the synthesizer and a tube assembly extending above the keys that produces drops of liquid that fall periodically onto the keys to produce a melody.

Abstract: A taxi meter system mounted on a taxicab for accurately computing a fare for a taxicab trip as function of time and distance is disclosed. The system provides discrimination means that eliminate the contribution to the fare that may otherwise be created by illegal means that degrade the performance of the taxi meter system.

Abstract: A black light display device is provided which utilizes a black light source in combination with fluorescent/phosphorescent display elements which can be thread, strings, monofilaments, disks or sculptured material. The display elements are formed about a spindle which is secure by fixed in a housing which houses the black light source and the fluorescent/phosphorescent elements. One form of housing comprises selectively removable transparent barrier which is transparent to the visible light radiating from the fluorescent display elements but opaque to the ultraviolet light radiating from the black light illumination source.

Abstract: A writing instrument has an ink containment tube and a pen tip equipped at one end of the ink containment tube with an oily ink contained in the ink containment tube. The oily ink shows pseudo-plasticity fluidity and comprises a colorant, a resin, an organic solvent and a gelling agent.
