Abstract: A composition useful for preparation of a graffiti-resistant barrier coating, related methods and compositions. The composition comprises from about 0.1 to about 30 percent by weight polyvinyl alcohol of molecular weight from about 7,000 to about 120,000 and being at least about 50% hydrolyzed; from about 0.1 to about 30 percent by weight non-stick agent such as silicone or polytetrafluoroethylene; and from about 0.1 to about 40 percent by weight adhesion promoter such as a urethane composition.

Abstract: A surface coating composition and method for applying the same to the inorganic substrates. The composition comprises a moisture-curable aqueous urethane dispersion, a cross-linking agent and an anionic surfactant, wherein the anionic surfactant has a phosphate group substituent. The aqueous urethane dispersion comprises discrete linear aliphatic urethane chains and the several chains are linked together upon curing.

Abstract: An additive for transformer oils comprising a non-ionic fluorosurfactant and a halogenated hydrocarbon where the co-mixture is a liquid at least 70.degree. F. and methods for preparing and using same. The halogenated hydrocarbon is preferably chosen from the group comprising C.sub.1 -C.sub.3 alkanes which can be fully halogenated or can retain some hydrogen atoms on the structure. The most preferred halogenated hydrocarbons being dibromotetrafluoroethane, dibromodifluoromethane or bromochloromethane. The most useful surfactants for use in this invention are those that are capable of dispersing and holding a halogenated hydrocarbon evenly throughout an oil. This is best accomplished through use of a non-ionic fluoro-surfactant. The additive of this invention can be used with any transformer oil to increase the useful life of the oil as well as to enhance the operational parameters of the transformer.

Abstract: A recoil protection system is disclosed which includes a fabric yoke. A leather panel is stitched to the yoke with a foam pad confined in the volume between the leather panel and the yoke. The foam pad is sized with its rest volume somewhat larger than the volume defined by the leather panel and the yoke such that the foam pad is in a constant state of compression. The foam pad is formed of a material having a high Loss Factor, and the yoke is held in place on the shoulder of the user by means of a harness which includes first and second straps, each of which passes under a respective arm of the user. Preferred materials for exceptionally effective foam pads are disclosed.

Abstract: A record handling device is disclosed which includes a frame which defines a handle and an arcuate record contacting member. This contacting member defines an arcuate groove sized to receive the peripheral edge of a record. A record retaining member is pivotably mounted to the frame so as to move between an open position, in which a record can freely be inserted in or removed from the groove, and a closed position, in which the record is captured in the groove. The record gripping device of this invention allows a record such as a phonographic record to be handled and transported safely and securely, without damage to the delicate recording surface. In addition, an album opening device is disclosed which comprises a groove defined by two sloping sidewalls and a base, and a blade situated within the groove.

Abstract: A demagnetizing device for a cassette tape player includes a cassette shell which defines a generally oval-shaped guide track extending around the interior of the shell. A magnet assembly is provided with shafts which fit within the guide track such that the magnet assembly is free to rotate within the guide track and to translate along the length of the guide track. The magnet assembly is rotated by a drive belt which in turn is driven by two hubs rotatably mounted in the cassette shell. An automatic shutoff lever is disclosed which acts automatically to shutoff a tape player equipped with automatic shutoff features when the magnet assembly reaches one of two predetermined positions on the guide track. By properly positioning the guide track, the single magnet assembly can be used to demagnetize multiple components of a tape player distributed around the cassette shell. For example, the single magnet assembly can be used to demagnetize two capstans and a tape head in a single operation.

Abstract: A phonograph tone arm and cartridge damping system in which a damper is coupled to a tone arm having a cartridge at one end thereof or to the cartridge itself and is adapted to ride on the surface of a record to minimize the effect of surface warps on the tone arm and cartridge. The damper includes a housing, a low friction piston slidable within the housing, and a glider adapted to ride on the surface of the record. The piston has an orifice therethrough to permit ambient air forced through the orifice to serve as the damping medium, or the piston and the housing have a preselected spacing between them to allow ambient air to flow therethrough. The glider has attached thereto a piece of soft velure or pile fabric, or a plurality of brush tips, which act to minimize friction between the glider surface and the record.

Abstract: A broad and flat housing of low height with a closed interior chamber to contain a phonograph record, the housing having reclosable access to the chamber, nozzle openings to direct film emission material across the face of the record in the chamber.

Abstract: A cleaning composition with anti-microbial properties and for use in cleansing metal, plastic, or glass surfaces, the mixture includes a surfactant, an emulsifier, an anti-microbe, all intermixed in a liquid carrier. This composition is most effective when used in combination with a brush design having a cloth cover whose projecting filaments form a pile that are maintained angularly, and which when brushed against said pile effectively loosens dirt particles from the foregoing type surfaces. In a method of use of this invention, the cleaning composition may be applied to the leading edge of said brush pile, with the brush then being moved in a rolling action upon the surface being cleaned, as for example, phonograph record surfaces, thereby to effectively clean any dirt or microbial particles that may be clogging the micro-grooves of the same.

Abstract: A cleaning composition of high chemical activity with anti-fungal properties, and with low dry weight residue and particularly useful for cleaning the surface of phonograph records; the mixture includes a surfactant, an emulsifier, an anti-microbe or fungicide, all intermixed in a liquid carrier such as water. This composition is most effective when used in combination with a brush designed having a cloth cover whose projecting filament form a pile that is finished and maintained angularly, and which when brushed against this pile effectively loosens dirt particles from the phonograph record surfaces being treated.
