Abstract: Magnets secure a pattern and a fabric on a magnetically-attractive substrate including a top layer of a resilient material that is well-suited to receive a sharp edge to produce a clean cut in the fabric being cut. A kit according to the present invention includes a plurality of magnets, preferably of various sizes and shapes, and at least one magnetically-attractive substrate. The kit can have a plurality of substrates, fasteners for holding the substrates together, a cutting tool and packaging. At least one of the magnets includes a magnetic portion having a bottom surface and a nonmagnetic portion extending laterally from the magnetic portion.

Abstract: Magnets secure a pattern and a material on a magnetically-attractive substrate, so that the material can be cut accurately and precisely in accordance with the pattern. The magnetically-attractive substrate includes a top layer of a resilient or other material that is well-suited to receive a sharp edge to produce a clean cut in the material being cut. A kit according to the present invention includes a plurality of magnets, preferably of various sizes and shapes, and at least one magnetically-attractive substrate. The kit can have a plurality of substrates, fasteners for holding the substrates together, a cutting tool and packaging.

Abstract: A cutter head with at least one insert clamp. Each insert clamp includes a wedge member fastened to the cutter head. The cutter head includes an insert slot, a clamping slot, and a threaded aperture. The wedge member, in one embodiment, is wedge shaped and includes a thru-opening. A fastener engages the threaded aperture in the cutter head and passes through the thru-opening in the clamping member. A cutter insert fits into the insert slot in the cutter head, and the wedge member secures the cutting insert against a surface of the cutter head.

Abstract: A liquid chemical formulation suitable for making a thin solid polycarbonate film of highly uniform thickness is formed with polycarbonate material, a liquid that dissolves the polycarbonate, and possibly one or more other constituents. The liquid is typically capable of dissolving the polycarbonate to a concentration of at least 1% at 20° C. and 1 atmosphere. The liquid also typically has a boiling point of at least 80° C. at 1 atmosphere. Examples of the liquid include pyridine, a ring-substituted pyridine derivative, pyrrole, a ring-substituted pyrrole derivative, pyrrolidine, a pyrrolidine derivative, and cyclohexanone. In forming the polycarbonate-containing film, a liquid film (36A) of the liquid chemical formulation is formed over a substructure (30). The liquid film is processed to largely remove the liquid and convert the polycarbonate into a solid film (38).

Abstract: A technique for creating openings in a polycarbonate film entails providing a liquid chemical formulation that contains polycarbonate material, a liquid that dissolves the polycarbonate, and possibly one or more other constituents. The liquid is typically capable of dissolving the polycarbonate to a concentration of at least 1% at 20.degree. C. and 1 atmosphere. Examples of the liquid include pyridine, a ring-substituted pyridine derivative, pyrrole, a ring-substituted pyrrole derivative, pyrrolidine, a pyrrolidine derivative, chlorobenzene, and cyclohexanone. A liquid film (36A) of the chemical formulation is formed over a substructure (30) and processed to remove the liquid, thereby converting the liquid film into a solid polycarbonate track layer (38). Charged particles (70) are passed through the track layer to form charged-particle tracks (72) at least partway through the layer. Apertures (74) are created through the track layer by a process that entails etching along the tracks.

Abstract: The invention is directed to controlling and alleviating itchiness of human skin. Itchiness is treated with a composition that includes inositol phosphate, particularly phytic acid and its salts, in a cosmetically acceptable carrier.

Abstract: Cosmetic compositions are described wherein .alpha.-hydroxyacids, .alpha.-ketoacids and related compounds are formed into amine salts through neutralization with a multi-amine functionalized polymer. Particularly preferred are glycolic acid and lactic acid salts of poly(ethylenimine).
