Title: Equivalent circuit for telephone choke coil - uses MOSFET exhibiting drain current when gate-source voltage is zero
Inventor: SZECHENYI KALMAN DIPL ING
IPC: H03H11/48
Filed: 1980-10-02
Abstract: The equivalent circuit uses a MOSFET exhibiting a high breakdown voltage with its voltage threshold adjusted by ion implantation in the channel region, so that a drain current is present when the gate/source voltage is zero. The gate and substrate terminals of the MOSFET are coupled to the drain or source. The MOSFET is connected between the wires of a telephone line via two service resistors either side of it. The junction between each resistor and the MOSFET is connected to earth via a pair of opposing Zener diodes connected in series. A pair of series spark gaps are also connected across the lines, with the junction between them coupled to earth. The circuit can deal with voltages of 800 volts across the speech wires and voltages of 1200 volts between each speech wire and earth.

Title: PABX with priority facility - enables selected extension subscriber's appts. to change priority as desired
Inventor: ACHMUELLER ANDREAS ING GRAD
IPC: H04M3/38
Filed: 1980-09-30
Abstract: Selected subscribers appts., or all if need be, are fitted with keys by which one of several orders of priority can be selected. When a call is initiated and a priority selected this information is passed to a memory in a central processor. Here it is evaluated and appropriate signals sent to the exchange system to execute the call. The freely selectable priority means that if a number is engaged it can still be reached by exercising a higher priority. The existing connection is then interrupted. The memory and processor are arranged so that top priority can only be assigned to one subscriber at any one time.

Patent DE-3107860-A1 (DE)
Title: Rubber wind-up motor
Inventor: KUTSCHAT HORST
IPC: B62M21/00
Filed: 1981-03-02
Abstract: The invention relates to a motor which is wound up via rubber strands when pedalling normally. In each case one rubber strand, mounted in the longitudinal direction on ball bearings, is attached on the left-hand side and right-hand side of the bicycle frame. The rubber strands are as long as the bicycle. By virtue of a favourable transmission via the pedalling mechanism of the bicycle to the rubber strands, the bicycle is no longer directly driven via the chain after riding for an initial short period, but via the rubber strands. By virtue of the high wind-up ratio, the motor is wound up quicker than it is possible for the wheels to turn in relation to the winding up process. This means that with a uniform, slow pedalling movement the bicycle becomes increasingly fast and the rubber strands are wound up more and more tightly. The cyclist must therefore cease pedalling from time to time until the wind-up motor has run down again. Until the wind-up motor has run down again, the cyclist can enjoy riding the bike without pedalling. On a flat stretch, riding the bike is particularly favourable since the winding up of the rubber motor takes no more effort than the effort in normal cycling where a wind-up motor is not used. A finished model has already been tested for over a year by various people.

Title: Arrangement for avoiding crack formation on the inner surfaces of feed-water pipe pieces opening into pressure vessels
Inventor: MAYER HANS DIPL ING
IPC: F22B37/22
Filed: 1981-07-20
Abstract: Arrangement for avoiding crack formation on the inner surfaces of feed-water pipe pieces (13) opening into pressure vessels, in particular nuclear reactor pressure vessels or steam generators. The introduction of the feed water into the water/vapour space (II) of the pressure vessel (DE) takes place via an essentially horizontally running pipe part (140) and, following this, a rising pipe part (141) as far as overflow edges (Ü) at the flow path end of the rising pipe part (141). From there, the feed water is, via a downwardly directed pipe piece (142) and if appropriate via an annular feed-in pipe (12) connected thereto, added to the medium in the water/vapour space (II) or in the fall space (8) of the pressure vessel (DE).As a result, a temperature layering due to flowing back of warmer water in the pipe is prevented. In this connection, it is important that the An/Di ratio is dimensioned to be as small as possible. A ratio which lies approximately between 0.5 and 2 has proved to be workable in practice. (An) means here the horizontal spacing of the pressure vessel inner wall from the central line (Mu'') which runs through the centre of gravity of that cross-sectional surface which is spanned by the overflow edges (Ü). (Di) means the inner diameter of the feed-water line which opens into the pressure vessel. <IMAGE>

Title: Liquid-cooled internal combustion engine provided with a lubricant circuit
Inventor: FRICKER LUDWIG DIPL ING
IPC: F01P11/08
Filed: 1981-07-23
Abstract: In a liquid-cooled internal combustion engine the main oil duct is laid in the cylinder head so that it is located above the cooling water chambers through which cooling water flows. The oil there absorbs heat according to the engine operation or gives off heat and only then does it pass by way of secondary oil ducts to the usual lubrication points. Measures of this type are intended to speed up the oil heating process in the warm-up phase and in addition to prevent a fall of the oil temperature in partial load operation of the internal combustion engine.

Title: Device for energy saving, in particular in heated or air-conditioned rooms
Inventor: HEILAND GEB KLEINSCHMITT
IPC: G05D23/19
Filed: 1981-11-27
Abstract: The present invention relates to a device, with the aid of which unnecessary energy losses, in particular in heating or air-conditioning installations, preferably in living or business premises, administration buildings or parts thereof (individual rooms) can effectively be avoided. Since the energy requirement, in particular for the production of heat or cold in rooms used by people is greater than in those not used by people, energy (in particular heating or cooling energy) can be saved in that, in all the rooms not used at the time by people, this energy supply is reduced or interrupted by a "presence-dependent or absence-dependent control". Thus, in the absence of people, the temperature difference between (used) rooms and environment can in fact be reduced, which leads to a smaller heat flow between room and environment and consequently to the desired energy saving.

Title: Temperature-sensitive hydraulic clutch
Inventor: KIKUCHI YASUBEE
IPC: F16D35/02
Filed: 1981-12-17
Abstract: A temperature-sensitive hydraulic clutch transmits the torque from an input shaft to a driven seal housing via a fluid and controls the rate of such torque transmission as a function of variations in an ambient temperature. The housing is mounted on the input shaft and has a casing, on which are secured fan blades, and a casing cover secured on the casing. The interior of the housing is divided into an oil reservoir and a torque-transmission chamber by a transverse wall which has a flow-adjusting opening which can be opened and closed by a valve part which is riveted to an intermediate wall and is connected via a connecting rod to a temperature-sensitive element such as, for example, a bimetallic element secured on the outer surface of the casing cover. A driving disc is arranged in the torque-transmission chamber, with a narrow interspace defined by the disc and a surface of the housing which forms the torque-transmission chamber. In the interior, the housing has a barrier which is arranged in a region where oil is collected due to the centrifugal forces which arise during the rotation of the driving disc. Oil is controlled by the barrier so as to flow from the torque-transmission chamber to the oil reservoir via a circulation passage formed between them in the casing cover in order in this way to effect an increase or a reduction in an effective surface of contact of the oil between the driving disc and the casing within the narrow interspace as a function of changes in the ambient temperature. One end of the connecting rod is passed either through the bimetallic element or the valve part and its other end, which is held in a supporting manner by the other part, with the result that the connecting rod can be rotated about its own axis in order to adjust its axial extent or length for the actuation of the seal part in order to open the flow-adjusting opening when the bimetallic element is at a desired ambient temperature. <IMAGE>
