Patent DE-2425354-A1 (DE)
Title: Socket outlet for wiring installations - shutters protect live parts when plug is removed
Inventor: MARTHEN HORST
IPC: H01R13/453
Filed: 1974-05-25
Abstract: The object is to improve the safety of domestic socket outlets by placing a shutter in front of the live connections when the plug is withdrawn. The shutters are operated by the plug, and thus the insertion of foreign items into the live sockets prevented. The live parts (21) are in the socket base (17). The shutters (19) are in the bottom of the plug recess and have arms (28) extending outwards along the line of the slots normally used for polarising and earth connections. The shutters are held in position by a garter spring (15). Inserting the plug presses the arm radially outwards thus opening the shutters and allowing the plug pins to enter the sockets.

Title: Waterproofing plastic-insulated communication cable - involves pumping viscous filler under pressure into filler tube enclosing cable sheath
Inventor: OESTREICH ULRICH DIPL ING
IPC: H01B13/32
Filed: 1974-09-13
Abstract: A filler material, e.g. petroleum jelly, is supplied in the liquid state from a thermostatically controlled storage container (1) to the vicinity of a filler tube (3) enclosing the cable sheath in a pressure-tight manner. The temperature of the filler material, shortly before the filler tube (3) is reached, is reduced to the solidification range and the highly viscous filler material is supplied by a screw pump (6) under pressure (3-30bar) to the filler tube, this having a length adapted to the filling pressure and filling time at the prevailing temperature. The supply line (2) between the tank (1) and the filler tube (3) contains a gear pump (4), a controllable heat exchanger (5), a screw pump (6) and a distributor (7) with a pressure vessel (8). The heat exchanger (5) is pref. cooled by air or water.
Patent DE-2444502-A1 (DE)
Title: Shaft seal with automatic repulsion of fluid - by self orienting fibres on seal surface which adopt oblique positions
Inventor: FORCH HANS DIPL ING
IPC: F16J15/3244
Filed: 1974-09-18
Abstract: A flexible shaft seal, pressed radially or axially onto the shaft optionally by a spring comprises a number of fibres projecting out from the sealing face of the seal., so that their free ends point towards the fluid side which is to be sealed. Thus, as the shaft rotates, the fibres become deflected and adopt a position at an angle so that they tend to force fluid back against the direction in which it is endeavouring to penetrate the seal. The fibres may be attached to the face of the sealing ring or formed of the fibrous matl. of the ring itself, in partic. where the ring is of a non-woven matl. A sealing ring with unoriented projecting fibres may be used, in which the dia. of the surface is smaller on the medium side than on the other side. The seal has a self-adjusting twist which always ensures, regardless of the direction of rotation of the shaft, that the angle of the fibres deflects the fluid back to the side from which approaches.

Patent DE-2516367-A1 (DE)
Title: Regulated mains power unit - insensitive to interference, uses small components carrying only part of load current
Inventor: HARREL JACK D
IPC: G05F1/573
Filed: 1975-04-15
Abstract: A regulated mains power supply unit designed to reduce interference, has an auxiliary control and current unit (16) with a regulator (21) having three terminals in parallel with the load (28) designed for a current less than a predetermined maximum current. One or more bridging paths (31, Q2, 33) in parallel with the first path shunt a current equal to the difference between the total current taken and the maximum of the regulator, when the total current is less than a predetermined level. Switching units (Q1) transfer current to the regulator if the total current exceeds this predetermined value, so that the regulator can act as a limiter. The circuit can also trip if the maximum is exceeded. Design of the unit is simplified since the regulator unit itself does not have to carry the full load current so that smaller components can be used.

Title: Radial cylinder IC engine cooling - by using excess of scavenging air admitted during exhaust stroke
Inventor: TOWNSEND RAY THEODORE
IPC: F02B75/02
Filed: 1975-07-15
Abstract: The engine has a stationary casing of two halves (12, 14) bolted together axially. the shaft (26) carried in a bearing (28) in one half is attached to a rotor (136) which has four cylinders (168) at right angles. The pistons (184) have rollers (190) which run on a cam disc (18) held between the two halves of the casing which is shaped to provided a reciprocating motion to the pistons as the rotor turns. The rotor turns about a stationary stub (36) in the centre of the casing which has a connecting pipe (66) to a compressed air reservoir. The air passes through channels within the stub to ports in the rotor which admit it to each cylinder on the exhaust stroke. The quantity of air is so admitted is sufficient to provide a high degree of cooling.
Patent DE-2535465-A1 (DE)
Title: Industrial froth abatement system - in which rising f.oth contacts an electrode of a transistorised circuit which operates an antifoam additive pump
Inventor: KALLENBACH HARALD
IPC: G05D9/12
Filed: 1975-08-08
Abstract: Froth in sewage treatment plants, textile and sugar factories and in paper making machinery is removed by the addn. of antifoam agents. A control electrode is arranged above the fluid level to be monitored and is contacted by the electrically conductive froth when the latter rises. This switches on a pump which sprays an antifoam agent in the fluid. A potentiometer in the circuit is used to adjust the sensitivity to response. This saves the injection of antifoam agents when no froth is produced. It can deal with sudden rises in froth prodn. better than a constant injection.
