Abstract: Zirconium precursors for use in depositing thin films of or containing zirconium oxide using an MOCVD technique have the following general formula: Zrx(OR)yL, wherein R is an alkyl group; L is a &bgr;-diketonate group; x=1 or 2; y=2, 4 or 6; and z=1 or 2.

Abstract: A composite element comprising a reinforcing fabric framework comprising at least one assembly of separate tubular fabric formations bonded in an impregnating synthetic resin material.

Abstract: A rack, for caulking guns or the standard cartridges which fit them, includes upwardly-projecting cones adapted to plug the opened plastic nozzles of caulking cartridges when the cartridge nozzles are lowered onto the cones. An air-tight seal is formed as the plastic nozzle of a cartridge conforms to and grips the cone. The weight of the cartridge helps to insert the cone. The rack includes grips disposed above the cones for holding either cartridges, or guns with cartridges therein. The grips are of the resilient arm type, preferably with rubber-covered arms so the that the cartridges, after being forced down onto the cones, will not work upward. The rack includes a serrated nozzle-cutting edge and a holder for a nail to puncture the inner membrane of a cartridge.

Abstract: A fabric reinforcement for use with synthetic plastics material to produce a composite article is shaped to exhibit a tubular portion having a longitudinal axis, which can be curved, and at least one flange extending in the direction of the longitudinal axis. Using up to several interlinked tubular portions and a plurality of the flanges gives wide possibilities for the shape of the fabric reinforcing elements produced. Woven or knitted fabrics can be used.
