The present invention is an imaging element which includes a support, an image forming layer superposed on the support; and at least one layer superposed on the support. The at least one layer superposed on the support is formed from a non-aqueous coating composition of a composite wax particle composed of a wax phase and a non-crosslinked polymer phase and an organic solvent. The wax phase includes a wax having a melting point of greater than 30.degree. C. The wax comprises greater than 80% by ...

A building structure, as for a conservatory roof, in which hollow building panels of a plastic material are connected side-by-side by upper and lower coupling members, between adjacent building panels. The coupling members receive aluminum reinforcing beams having longitudinal slots, in which the lower coupling members are held together. Each building panel has an integral cap, which covers the upper coupling members of two adjacent building panels for holding the adjacent building panels togeth...

Vinyl sulfone and/or .beta.-halo sulfone compounds have been found to improve fog stability on shelf aging of photothermographic imaging elements. These elements comprise a photosensitive silver halide, silver salt oxidizing agent and reducing agent for silver ion in a binder.

A drying element for use in a printer, with an electrical heating device through which blown air flows and with a blower duct which distributes the warm blown air transversely to the conveying direction of the printed products, wherein a rod-shaped infra-red radiator extends parallel to the surface of a heating tube located upstream of the blower duct and has a surface absorbing infra-red radiation, said blower duct extending parallel to the heating tube and being connected to the latter by way ...

An abrasive element comprising a substrate having on a surface thereof particles of an abrasive material secured by an organic binding medium wherein at least the surface of the element between the particles of abrasive material contains a fluorochemical selected from the group consisting of compounds comprising a fluorinated aliphatic group attached to a polar group or moiety and compounds having a molecular weight of at least 750 and comprising a non-fluorinated polymeric backbone having a plu...

This invention comprises a photothermographic element comprising a support bearing an imaging layer comprising: a silver salt; a reducing agent; a binder; and a photosensitive material comprising silver iodide produced by dispersing a solid ionic conductor of the formula MAg.sub.4 I.sub.5 in an organic solvent, whereby the solid ionic conductor decomposes to produce silver iodide, and wherein M is a monovalent cation and said solid ionic conductor has an ionic conductivity of >0.001 ohm.sup.-...

The invention is concerned with security elements for security articles such as banknotes, cheques and the like. The invention further comprises a security element for use with security materials, said element comprising a first layer, to one side of which is applied at least one optically variable device, and on the other side of said first layer are applied indicia, and a thermochromic coating applied over the indicia, wherein the thermochromic coating comprises a thermochromic material which ...

A waveguide element is formed of a body of plastics resin, such as, acrylonitrile-butadiene-styrene resin, having a tubular portion open at its opposite ends and flanges directed outwardly at such ends, and a conductive layer, for example, of an electroless plated metal such as tin-cobalt alloy, covering the inner surface of the tubular portion and the surfaces of the flanges which face axially in the directions that the respective ends open. For ease of molding or forming the body of plastics r...

A connector for intersecting structural members which connector has a hollow box-shaped central portion and fins projecting from the outer corners thereof to form with the sides of such central portion opposite aligned channels which receive the end portions of mitred, abutting, intersecting structural members.

A hollow building element of plastics material comprises one or more longitudinal ducts and having, at opposite sides thereof, coupling members, whereby elements may be connected to each other, a coupling member at one side comprising a duct for receiving a reinforcing beam and having a ducted bottom wall.
