IPC: H02G15/24

Abstract: In a termination for a fluid-filled cable, the insulator 2 has an imperforate metal end-fitting 3 so that the risk of leakage of fluid into or out of the cable is negligible, whichever direction the pressure differential may be in - this makes the termination especially suitable for pressurised gas switchgear. A terminal 6 on the cable conductor end is connected to the end-fitting 3 by a plug-and-socket joint 4 and 5, and there is also a direct shoulder to shoulder engagement to transmit compressive forces. A latching mechanism comprising for example retractable pins 7 which ride up camming surfaces 10 and engage shoulders behind them, holds the plug-and-socket engaged against tensile forces.

Abstract: A transfer pump (22) draws fuel from a tank (12) and feeds it via a temperature sensor (38) to an injection pump (30) from which approximately 50% of the fuel is returned as surplus, heated fuel. This fuel is proportioned by a valve (40) between a return line (33) to the tank and a bypass line (42) transferring fuel to the inlet of the transfer pump (22). When the fuel is cold, all or most of the surplus fuel is returned to the transfer pump with the valve (40) in the illustrated position. As the fuel warms up, progressively more of the surplus fuel is returned directly to the tank and the transfer pump only utilises fuel drawn from the tank via a feed line (14). When the engine is running, a shutoff valve (20) has the illustrated position and connects the feed line (14) to the inlet of the transfer pump and connects the outlet of the transfer pump, downstream of the temperature sensor (38), to the inlet of the injection pump (30). To shutoff the engine, the valve (20) is operated to a second position in which it starves the injection pump by connecting the inlet of the injection pump to the inlet of the transfer pump and connecting the outlet of the transfer pump, downstream of the temperature sensor, to the line (14) which then is a return line.

Abstract: A bioelectrode for use in the iontophoretic delivery of ions into the skin or tissue of a person includes either a receptacle or a composition of material suitable for holding ions to be delivered, a metallic foil disposed on one side of the receptacle or composition of matter, and a coupling device for electrically coupling the foil to an electrical source. The other side of the receptacle or composition of material is for placement against a person's skin or tissue so that ions may be delivered thereinto. The receptacle or composition of material both include features or characteristics which inhibit the migration of ions laterally therein, i.e., in a direction generally parallel to the surface of the skin or tissue, but which allow migration in a direction generally perpendicular to the surface of the skin or tissue, and in particular from the metal foil toward the person's skin or tissue. The advantage of this capability is to provide a substantially uniform movement of ions into the skin or tissue over surface area of contact of the bioelectrode with the skin.

Abstract: Tape (11) is wound into a package by traversing the winding position along a cylindrical core (21) such that the winding position is intermittently and repeatedly halted at a plurality of positions arranged axially of the core (21) so that at each position the tape (11) is wound spirally following which the winding position is traversed to the next adjacent position. The spirals comprise at least one turn and more of the winding time is spent in forming spirals than in traversing between spirals. The spacing between the positions is such that the spirals do not overlap and such that the gap between the spirals is less than the width of the tape (11). The number of spirals wound at each position is insufficient to cause a step which interferes with traverse back to the position. Control of the traverse movement can be achieved either electronically by a pulse counter connected to the package support shaft or electro-magnetically by a control drum driven from the package support shaft.
