Abstract: A stud removing tool for removing a threaded stud from an associated stud mounting member having an elongated sleeve member with an internally threaded gripping end and an internally tapered stud locking end. A pilot member having a closed drive end, and an internally threaded bore end is provided. The drive end has an external angle of taper less than the internal angle of taper of the sleeve member, in which the angle of taper increases as it is directed toward the internally threaded bore end. The bore end of the pilot member has multiple finger splits directed from the open end to the closed end. When the tool is in use, the pilot is co-axially disposed in the sleeve member, with the bore end of the pilot threaded onto the end of a stud. A plug member is provided, having a driving end and an externally threaded mating end adapted to engage the internally threaded gripping end of the sleeve member and to axially abut the closed end of the pilot member.

Abstract: A tool for producing a pattern of highly accurate optical quality surfaces and the method of making same from a series of bi-metallic pins. A high strength metal pin is coupled to a slug of metal of lesser strength capable of being accurately scribed. The supporting pin blank preferably is magnetic stainless steel and the slug is of copper. A group of such bi-metallic pins then is placed in an appropriate fixture after which an optical configuration, such as the three faces of a cube-corner element, are scribed into the copper ends. A completed tool may then be electroformed to produce an electroformed tool from an array of the like or different pins, arranged in various patterns.

Abstract: A retroreflective relatively flexible laminate sheet construction has a thermoplastic web with a smooth light-receiving first side and a second side coextensive with said first side. A retroreflective pattern is formed on the second side. A slurry of granular material is deposited on the second side to cover selected portions of the formed pattern with remaining portions of the formed pattern devoid of the granular material, and said slurry is dried or cured to produce a well-defined pattern. A layer of backcoating material is deposited on the second side to overlay the granular material, the backcoating material contacting the thermoplastic web where no granular material has been deposited, thereby encapsulating the granular material between the second side and the backcoating layer. An added, outer layer provides additional weather protection for the thermoplastic web. Methods are detailed to manufacture the laminate, and compositions of backcoating mixtures also are disclosed.

Abstract: An improved method of treating acne vulgaris comprising administering a therapeutically effective amount of carbamide peroxide alone or in combination with one or more of a topical antibiotic, nicotinic acid or nicotinamide and compositions useful in said method.

Abstract: A shelf assembly comprising a plurality of parallel spaced platform members and a plurality of spaced frame members fixedly connected to the platform members so as to define a grid-like shelf, each of the frame members extending normal to the platform members and each having distal ends extending beyond the outer most platform members. A pair of allochirally configurated shelf end support brackets is provided, each end bracket having means for freely supporting the distal ends of the frame members so as to support the shelf in a generally horizontal plane when the support brackets are secured to an associated wall.

Abstract: A method and composition for preventing and treating irritation of the mucous membranes of the nose wherein a tricyclic anti-depressant topically applied to the nose is effective prophylactically to prevent irritation and a combination of the tricyclic anti-depressant with a vasoconstrictor is effective to prevent and to alleviate irritation of the mucous membranes of the nose.

Abstract: Disclosed herein are an improved method and apparatus for continuously embossing a repeating pattern of precise detail, in particular, cube-corner type reflector elements, on one surface of a single sheet or on one surface of a laminate of transparent thermoplastic materials, to form retroreflective sheeting. A continuous embossing tool in the form of a flexible thin metal belt or cylinder has on its outer surface an embossing pattern which is the reverse of the precision optical pattern to be formed. The embossing tool is continously moved at a predetermined speed along a closed course through a heating station where the temperature of a portion of the embossing tool is raised to be above the glass transition temperature of the sheeting or laminate and a cooling station where the heated portion of the embossing tool is cooled while in a relatively planar condition to be below that glass transition temperature.

Abstract: A thin transparent glass sheet is bonded to the substantially flat planar front face of a cube-corner-type retrodirective reflector formed of a light-transmitting synthetic organic resin for covering at least the reflex reflective area thereof. A liquid urethane resin radiation curable to a transparent solid state is applied to the front face of the reflector and one side of the glass sheet is coated with a silane solution which is allowed to dry, and which side is then placed against the urethane resin on the reflector front face and pressed thereagainst until all air bubbles have been forced from the urethane resin and it has spread to a layer of predetermined thickness.

Abstract: The present invention includes an improved method of treating keratosis comprising periodically applying to the affected area a nail polish composition containing an effective amount of at least one corrosive agent for relieving the keratosis; also nail polish compositions are disclosed for use in the method.

Abstract: The invention relates to a method of treating herpes zoster in a patient having herpes zoster wherein an effective amount of capsaicin is topically applied to the area affected with herpes zoster for a time sufficient to relieve the symptoms thereof.

Abstract: A trimmer for eyebrows and other facial hair has relatively thin blade segments held by a thermoplastic fingergrip in an angled or "bent" configuration. The exposed, longitudinally extending edge of the blade segments are honed or otherwise sharpened and are used to position one such segment to sever selected facial hair while angling the other segments away from the face.

Abstract: A decorative noncombustible coating for application to combustible materials. The noncombustible coating includes monoaluminum phosphate; an inert coloring material such as titanium dioxide; phosphoric acid; a surfactant solution; and water in an amount sufficient so that the resultant coating has a surface tension of at least about 60, but not in excess of about 80 dynes per centimeter.

Abstract: A liquid storage and delivery system for protective masks has a hand-operable bulb siphon pump in line with conduits extending from a canteen assembly to the drinking mouthpiece of a protective mask. The canteen assembly includes structure adapted to flex in response to the partial vacuum created within the canteen assembly as liquid is withdrawn. An adapter may be used to enable use of the present system with prior art protective masks. A protective sheath covers at least a portion of the conduit to protect it against freezing, dirt, condensation, or physical damage.

Abstract: A mobile apparatus for detecting reflectivity of markers on a roadway surface is disclosed. The apparatus includes a vehicle and an elongated shroud assembly which has mounted therein a light source for directing light toward a marker and a light receptor for detecting light reflected from the marker, as the apparatus moves along the roadway surface. An aperture housing is mounted to the shroud and light directed to and reflected from the marker must pass through the aperture housing. In one embodiment the shroud is pivotally connected at one end to the vehicle and positioning means are provided for maintaining that portion of the shroud which will normally overlie the marker when light is reflected therefrom at a uniform and preselected height from the roadway surface. In another embodiment, the shroud is rigidly fixed to the vehicle, but the aperture is constructed to "float" at a uniform and preselected height from the roadway surface.
