Abstract: A bone grafting material is derived from allogenic or xenogenic bone by a process that includes tanning with glutaraldehyde. The bone may be pulverized, used as a large block, or machined into a precise pre-determined shape, depending on the bone defect to be repaired. Glutaraldehyde tanning of bone yields a stabilized, highly biocompatible, and non-antigenic material which becomes incorporated into host bone when placed adjacent to it.

Abstract: A tubular support bandage is made from a knitted fabric tube with a laid-in helical elastic yarn. The knit structure is arranged, for example, by providing courses of missing loops, so that different regions have different knit densities and the elastic yarns can move more closely together in the lower density regions.

Abstract: Means is described for performing a hair coloring treatment, such as tinting or bleaching, on a section of head hair and comprises a sheet of material capable of being folded around a section of hair to be treated. The sheet consists of plastics material and is re-usable in contradistinction to previously used aluminium foil. The sheet is also preferably transparent so that a hair coloring treatment can be monitored. At least one bendable inclusion in mesh, wire or strip form is embedded in or affixed to the sheet material, the bendable inclusion(s) having such bendability and rigidity that, when the sheet of plastics material is folded generally along predetermined fold lines over and about a section of hair to be treated with treatment material in paste or like form applied to the section thereby to form a generally closed pocket, the said inclusion(s) in bent form serve(s) to maintain the configuration of the pocket at least for a time sufficient to perform the coloring treatment.

Abstract: A blister bandage comprising at least one ply of an aerated latex microsized hydroentangled fabric, having an adhesive disposed on at least one surface of said fabric. The present invention has sufficient hydrophobicity in the fabric to be a barrier to liquid borne bacteria while preserving comfort, air permeability, and flexibility therein. In addition to the above properties, the bandage is sterilizable and will keep the skin beneath the bandage dry.

Abstract: An automatic hair curler comprising, in general, a U-shaped frame, a fixed shaft extending across the open top of the frame, a curling drum idly journaled on the shaft, a coil spring for energy storage, and ratchets to control drum rotation and coil winding. In use, the coil spring is pre-wound; hair tips are clamped to the drum; and the drum ratchet is disengaged, thereby allowing the spring to turn the drum thus curling the hair. An over-winding protection feature prevents excessive spring tension. A spring ratchet assembly, connected to the right arm, is connected to the spring inner end for controlling the coiling of the spring. The spring ratchet assembly has an engaged position permitting coiling of the spring and wherein rotation of the drum does not cause rotation of the spring inner end, and a disengaged position allowing the spring inner end to rotate and to uncoil the spring independent of drum rotation.

Abstract: This invention concerns a heterologous arterial biograft comprehending a heterologous biological material-made arterial duct, having its branches bound together (through micro technique) and keeping to a great extent its natural characteristics after submitted to a complete curing by a diabasic acid aldehyde aqueous balanced solution. The arterial duct shall preferably be a swine's or bovine's internal mammary artery.

Abstract: A disposable nail polish-removing thimble capable of quickly dissolving and removing the enamel coating from the surface of a fingernail or toenail, the thimble having a sufficient capacity to remove the polish from a full set of an individual's nails. The thimble is constituted by a miniature plastic cup having a peel-off cover, the cup housing a flexible foam plastic sponge saturated with an enamel solvent. The sponge has a center slit therein into which one may insert a finger or toe, the thimble then being rotated relative to the inserted member to remove the nail polish.

Abstract: A process, requiring minimal skills, for applying a protective acrylic coating, with or without extending the tips, to the human fingernail as afforded by (1) clearing and roughening the surface of the nail, (2) applying a layer of liquid acrylic monomer, (3) applying a powdered polymethacrylate ester to the wetted nail surface, (4) removing loose powder and smoothing the nail surface, (5) brushing on, as one would with nail polish, a second layer of liquid acrylic monomers and, after curing, (6) finishing the nail in the conventional manner.

Abstract: An appliance used for transferring and distributing weight applied by a patient's body member, is disclosed. It includes:(a) a first layer of synthetic flexible sheet material that forms a group of sealed, deformable air pockets distributed over layer area,(b) and an attachment or attachments associated with that layer for removably attaching same to the body member in weight supporting relation.

Abstract: A winding bandage for applying a compressive force to a body part including a knitted fabric strip comprised in part of a hydrophobic primary warp yarn, an elastic secondary warp yarn and a weft yarn. Flexible self closure members are attached to one or both ends of the fabric strip adapted to engage the fabric strip after the bandage has been stretched about the body part so as to secure the bandage thereto.

Abstract: A system of dyeing human hair is disclosed which is performed by layering the hair in tiers and selectively dyeing each layer. The tiers are annular elipsoids whose major and minor axes are in the same ratio and are fabricated in sets of ascending size. Each tier has disposed along its inner circumference, evenly spaced comb tooth-like projections.

Abstract: The specification discloses a wound dressing or like applique including an adhesively coated upper layer backed by a release liner wherein the upper layer is perforated and the release liner is cut, there also being a slit extending through both the release liner and the upper layer from the peripheral edge of the article to the perforation and cut lines in the respective upper layer and release liner. This facilitates removal of the offal portion from that portion of the upper layer which is to be adhered to a wound or other surface.

Abstract: A combined brush and roll-on cosmetic applicator comprising a rod, a spiral brush disposed within a shroud; the assembly of which gives a brush-like applicator with a row or rows of bristles rising perpendicular to the axis of the rod for the application of a cosmetic product.

Abstract: A high modulus endoprosthetic device comprising a polyaryletherketone and optionally reinforcement which may be fibrous, particulate or relatively massive. Loss of reinforcement to the body tissues may be reduced by provision of polymer rich layer at the surface of the device, particularly in locations where reinforcement is exposed at the surface or is likely to be exposed due to tissue or other abrasion.

Abstract: A mascara applicator is disclosed which includes a brush portion having a base and filament-like brush elements of molded plastic material. A plurality of the filament-like brush elements extend at right angles from the base and are integrally molded with the base. The brush elements may be of circular or elliptical cross sectional configuration of relatively fine dimensions. The elliptical cross section may have a major axis of 0.018 inches and a minor axis of 0.010 inches. The circular cross sectional tines can vary in diameter from approximately 0.014 inches at their bases to approximately 0.005 inches at their tips. In various modifications of the applicator, the base may also be equipped with a plurality of longitudinally spaced wells, with a plurality of longitudinally extending wells and with plurality of short tines.

Abstract: A medical-surgical dressing comprising a reinforced sheet of silicone elastomer foam having a thickness not exceeding 10 millimeters, one of the surfaces of the sheet having a surface layer of open cell foam and the other surface having a substantially non-cellular surface skin. The dressing may be manufactured by a process comprising depositing a liquid foamable silicone composition on an absorbent surface, allowing the composition to foam and set to an elastomer and thereafter separating the foam sheet from the substrate.The dressings are useful e.g. for the treatment of wounds, burns and as liners for plaster casts.
