Abstract: Disclosed is a topical composition for relieving pain in a person in need of such relief, consisting essentially of an effective amount of a combination of at least one corticoid analgesic, at least one arylpropionic acid type analgesic, and at least one p-aminobenzoic acid ester type local anesthetic; an amount effective in enhancing the effectiveness in relieving pain of the combination of capsaicin, and an amount effective to increase the transmission thereof of through the skin of at least one phospholipid and at least one polyoxyethylenepolyoxypropylene copolymer.

Abstract: The present invention provides a water soluble, inorganic pyrolytic paint which, when dried to form a paint layer, generates heat from a whole surface of the paint layer by supplying electric current therethrough. The pyrolytic paint is prepared by mixing and stirring together a mixture of metal carbide, metal oxide, metal nitride, metal boride and metal silicide, additive metal and a solvent containing sodium citrate, ethylene glycol, silicic acid anhydride and/or sodium silicate and water. When painted on a substrate surface and dried, the silicon dioxide component thereof forms insoluble macromolecular lands "L" by the condensation reaction of silanol base, which form a stable paint layer, and metal particles M thereof bridge the lands L and are supported thereby to provide uniform electric resistance throughout a surface of the paint layer, so that the paint layer can generate heat uniformly throughout the paint layer when electric current is supplied therethrough.

Abstract: Filter apparatus comprises a wall defining a chamber and a filter device mounted between an air inlet of the chamber and an air outlet thereof for filtering air passing therethrough. The filter device comprises a stiff frame defining an opening, and tubular pockets made of open weave mesh material. The pockets extend across the opening in spaced parallel relationship and contain vapor filter material.

Abstract: A fluid propelling and filtering apparatus with removable filter cartridge comprising a bottom wall, an annular top wall, and filter media disposed between and secured to the walls for securing the bottom wall to the top wall in parallel, spaced relation and for communicating fluid in through the annular top wall and out through the outer surface of the filter material. The filter cartridge is removably attached to an electric motor for imparting rotational movement to the filter cartridge. The filter cartridge and the motor are enclosed within a housing.

Abstract: Proximity sensor for determining the distance between a reflective surface and the sensor utilizes two output light guides positioned with the receiving end of one guide closer to the reflective surface than that of the other. When the surface is close to the guide ends a relatively greater intensity of light will be reflected to the second guide; when the surface is further away a relatively greater intensity of light will be reflected to the first guide. At a predetermined intermediate null position the reflected light intensities will be equal. The device has uses, inter alia, in accurately positioning objects without wear-producing contact, e.g. in numerically controlled machine tool operations; thickness sensing or thickness controlling using single or dual sensors; force sensing; liquid level indication; meter relay actuation; rotational limitation, and the like.

Abstract: A differential sensor unit precisely monitors ambient pressure within a confined space, such as blood pressure or intracranial pressure of a human patient, utilizing fiber optic light guides. Three light guides pass within a pneumatic line into one end of a rigid cylindrical envelope which may be inserted into a vein or artery or implanted in the skull. The other end of the envelope is bounded by a flexible membrane. Of the external ends of the guides, one faces a light source and each of the others faces a light detector. A reflective surface is attached to the internal face of the flexible membrane.

Abstract: Apparatus for mixing products within a generally flattened, flexible package having opposite side walls, comprising a support surface adapted to support one side wall of a package and mixing means adapted to contact an opposite side wall of a package on the support surface, the mixing means and support surface being mounted for rotation relatively to each other about an axis generally perpendicular to and intersecting the support surface. The mixing means includes package contacting means extending from the axis and generally parallel to the support surface and operating means for rotating the mixing means and support surface relatively to one another about the axis for mixing a product within the package during such rotation.
