Abstract: A method of anchoring an anchor element in a borehole comprises supplying self-setting composition into a sleeve while withdrawing the sleeve so that the self-setting composition fills the annular clearance between the element and the wall of the hole. Preferably the element is first secured within the hole by a self-setting resinous composition and, in order to provide additional corrosion protection for the element, the end portion of the element has a precast sleeve, and a plastics sheath is heat-shrunk on to the remaining portion of the element.

Abstract: An agent for stabilization of a decorative finish is incorporated in a timber preservative composition comprising a preservative e.g., fungicide, insecticide or fire retardant in an organic solvent e.g. white spirit, chlorinated hydrocarbon such as methylene chloride or a liquified butane or propane for use in a double vacuum treatment of the timber. The agent may be an alkyd resin or colloidal pigment of a defined mean particle size, or both.

Abstract: A cartridge containing a two component, self-setting composition. The cartridge comprises a tube formed of a flexible, rupturable material and having a first component of said composition sealed therein. A depression is formed in said tube with said depression being filled with a second component of said composition. The second component is sealed within the depression by sealing means. In one embodiment of the invention the sealing means comprises a strip of tape having an adhesive thereon. In another embodiment the sealing means comprises the joint formed between portions of the tube contiguous with the sides of the depression. In another embodiment the sealing means comprises a flap. The flap is created when said tube is formed by rolling up a strip of said rupturable material having two side portions wherein one side portion of the strip is sealed to the free edge of the other side portion and leaving a margin defining said flap. The flap is disposed over the filled depression and is sealed in place.

Abstract: An electrical conduit assembly comprises a box having at least one limb formed of synthetic resin and for receiving an end portion of a wire or a so-called "pot" connected thereto, and a compression ring, the limb having an integrally formed external male thread and the ring having an internal female thread whereby on locating the wire through the compression ring and screwing the ring onto the limb, the wire is held tight to the limb. A sheath having a flared annular rim at one end may be interposed between the wire and the ring.
