Abstract: A process for forming a colloid relief image on a substrate, comprising the steps of: (a) exposing to actinic light a sheet structure comprising a substrate having coated on one surface thereof a first layer comprising a colloid material capable of being tanned when contacted by oxidized silver halide developer, and coated over the first layer a second layer comprising a photographic silver halide emulsion, the emulsion containing substituted gelatin which is substantially resistant to tanning by the oxidized silver halide developers; (b) developing exposed sheet structure with oxidizable silver halide developers; and (c) washing the sheet structure with warm water, whereby all of the second layer is removed together with portions of the first layer which have not been tanned.

Abstract: Oligomers of highly purified methacryl substituted silanes, e.g., methacryloxyalkyltrialkoxysilanes, can be combined with (meth)acrylate monomers to give viscosities in a range such that they can be heavily filled for use in dental filling compositions. They can remain stable for extended times in contact with catalyst until initiated and are of particular value in two part dental filling systems.

Abstract: An attaching assembly for releasably attaching an osteotomy saw blade in a drive assembly. The attaching assembly comprises a drive member including a head portion having a slot adapted to receive an end portion of blade with a larger portion of an aperture in the blade aligned with a socket in the head portion, and a projection on the blade positioned in one of a plurality of notches in the head portion communicating with the slot. A locking button mounted in the socket is movable between a locking position (to which it is biased) at which a slightly tapered locking portion of the button is in engagement with walls defining the larger portion of the aperture to lock the blade in the attaching assembly; and a release position at which a narrow portion of the button is aligned with the slot so that the blade can be slid into or out of the slot with walls of the blade defining a narrow portion of the aperture communicating with an edge of the blade sliding past the narrow portion of the button.

Abstract: Silicone-coated release liner which, even after exposure to light in the presence of moisture, heat or both, displays release properties of less than 20 g/cm width with respect to pressure-sensitive adhesive tape. The coating contains noble metal, and the silicone polymer has substantially no residual ethylenic unsaturation. The silicone polymer is prepared by pre-reacting polydimethyl siloxane with a noble metal catalyst before adding polymethylhydrosiloxane crosslinker.

Abstract: A point focus radiation concentrator using two linear echelon surfaces crossed at approximately 90 degrees with the two linear echelon surfaces having a generally cylindrical shape with a radius of curvature approximately equal to the focal distance. The two echelon surfaces may be formed on separate sheets positioned in close proximity to each other or may be formed on opposite sides of a single sheet. The cross section of the curved concentrator surface may be circular or other aspherical shape, such as parabolic, ellipsoid and hyperbolic.

Abstract: An electromagnetic device having an armature mounted in the gap of a ferromagnetic core for selective contact of either of opposed pole faces. A source of latching flux retains the armature in contact with either of the pole faces while a flux return bracket conducts flux between the armature and the source of latching flux. The source of latching flux has a surface area perpendicular to the flux path greater than the length along the flux path creating a low reluctance path for a portion of the operating flux.

Abstract: Liquid level sensing circuitry useable for detecting the presence of an acceptable or unacceptable level for a liquid, such as engine oil. Prior to termination of the operation of the engine, the circuitry presents an unacceptable level indication at a control point. After completion of a time delay following termination of engine operation, an acceptable level must be presented for a time to cause an acceptable level indication at the control point which is maintained pending initiation of engine operation. Upon initiation of engine operation a first discernible indication is provided for a time period if the control point presents an unacceptable level indication with a second discernible indication provided for such time period if the control point presents an acceptable level indication.

Abstract: A method of transferring indicia from a first support base, such as a paper sheet, which is coated with a release agent, to a receiver surface, such as a wall or window. An adhesive surface is pressed against the first support base in order to transfer the indicia from the first support base to the adhesive surface. The adhesive bearing the indicia is then applied to a receiver surface to provide the receiver surface with a protected image. Preferably the indicia is a fused xerographic image and the release agent coated on the first support base is a unique radiation-curable fluorine-containing abherent coating composition.
