Abstract: A shoe for use with a fitting such as a lifting anchor or ferrule adapted to be cast into a reinforced concrete component, the shoe serving, in use, to locate tie-in bars relative to the fitting. The shoe comprises a body portion slidably received on a shank of the fitting, and clips for engaging with a snap-in action tie-in bars extending at opposite sides of the shank. The shoe can be retro-fitted to a pre-existing anchor assembly comprising an anchor, support, and void former.

Abstract: A distributed processing telephone system for providing “plug-and-play” capability. In particular, a key telephone system comprises a plurality of telephone sets. Each telephone set is coupled to at least one common communications channel, or telephone line, and includes at least one tunable RF modem. There is no key service unit (KSU). That is, the system is KSU-less. Resources of the telephone system are allocated using a peer-to-peer protocol. For example, as each telephone set is newly added to the system, the new telephone set adaptively determines its own allocation of resources, e.g., intercom numbers, etc. During operation, each telephone set requests the appropriate resources from its peers.

Abstract: A cleat for separately or simultaneously securing a rope and a chain has a pair of cleat horns projecting in opposite directions from an upright portion extending upwardly from a cleat base, the horns being spaced upwardly from the base. A chain link reception slot is downwardly inclined into the upright portion, and is open upwardly and to opposite sides of the upright portion, for receiving and retaining a link of a chain.

Abstract: A nitrogen PSA system uses a back-fill step only on start-up conditions or when a minor fault has caused the plant to temporarily lose purity. The plant utilizes an oxygen analyzer which controls valves allowing the initiation and cancellation of the back-fill step.

Abstract: An insulating composition comprises a polyolefin, preferably polypropylene, and hollow microspheres, at least some of which have been pre-treated with a chain-scission agent and, optionally, a functionalizing agent for the polyolefin, before addition to the polyolefin melt. The provision of the chain-scission on the microspheres enables the microspheres to be compounded substantially without breakage with low Melt Flow Index polyolefins, with the result that the resultant composite material can be employed in rigorous application areas, for examples as an extruded flowline insulation.

Abstract: A liquid dispensing gun employing an interacting bore, piston and piston rod which gun is provided with adjustment means to determine the volume of liquid delivered by the gun. The adjustment means being a series of projections extending radially from the peripheral surface of the piston rod and arranged thereon to selectively engage a circular member located around the rod, which circular member is provided with a series of recesses extending longitudinally adjacent the rod into which the projections may enter.

Abstract: A liquid dispensing gun employing two interacting bores and pistons to maintain the liquid inlet and outlet of this gun stationary with respect to the gun during operation. The gun is attachable to a liquid reservoir and may employ either a nozzle to deliver a dosage of liquid into the throat of an animal or to inject a dosage via a needle.
