Title: Electronic protection against drivers travelling in the wrong direction
Inventor: ECKER ENGELBERT
IPC: G08G1/07
Filed: 1983-07-05
Abstract: The electronic protection against drivers travelling in the wrong direction relates to a device which prevents one-way streets and motorways being entered in the wrong direction. Three electronic components located one behind the other are connected in the correct sequence when driving in the wrong direction, as the result of which a transmitter is triggered. By means of the encoded pulse sequence, the receiving component in the vehicle is triggered, as a result of which the engine is immediately switched off. This system can be produced with limited financial means but the effect is very great. If only one serious accident on a motorway is thus prevented, the system has already paid for itself over the entire country if the high costs entailed by such an accident are considered.

Title: Special tetrad adder/subtracter in the BCD 8421 code
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1983-08-05
Abstract: The tetrad adder/subtracter according to the inventive subject matter consists of a dual tetrad adder/subtracter (main circuit 17), which can be switched over from addition to subtraction, and a correction circuit 18 for subtracting the number 6 (LHHL) and the additional circuit 5 which has the effect that in the case of addition H potential is applied to the correction circuit 18 only if the carry output y has L potential and in the case of subtraction H potential is applied to the correction circuit 18 only if the carry output y has H potential. In the case of addition, one of the two summands must be input in BCD 6 code. In the case of subtraction, both the minuend and the subtrahend are input only in BCD 0 code. Consequently, in the case of addition the number 6 (LHHL) is subtracted from the result number of the main circuit 17 when the carry output y has L potential. Consequently, in the case of subtraction the number 6 (LHHL) is subtracted from the result number of the main circuit 17 when the carry output y has H potential. As a result, the result number is present in BCD 0 code in both cases of addition and in both cases of subtraction. <IMAGE>

Title: Vacuum regulating valve
Inventor: MEISEL RONALD MANFRED
IPC: F16K51/02
Filed: 1984-01-19
Abstract: The vacuum regulating valve is used to ensure unmistakeable, rapid, uncomplicated and reproducible setting from the outset in vacuum systems. It can be adapted to all intake capacities of vacuum systems. The awkward and time-consuming setting in the case of the previously known vocuum ventilation valves is at the same time eliminated.

Title: Circuit arrangement for connecting telephone stations to a line concentrator installation
Inventor: BRANDSTETTER ALFRED DIPL ING
IPC: H04M1/738
Filed: 1984-02-21
Abstract: The invention relates to a circuit arrangement for identifying the telephone station condition in line concentrator installations. The object is to implement a circuit arrangement of this type with the simplest possible means while retaining the required dielectric strength and polarity independence. To achieve this, a rectifier bridge is disposed between the subscriber line wires supplying the feed voltage and the identification voltage upstream of the hook switch contacts and two self-locking FETs connected in series with opposite polarity are disposed downstream of the hook switch contacts but upstream of the speech circuit which, when the station is in the idle condition, are controlled via the rectifier bridge and switch the station input to low for the identification voltage when the hook switch contacts close. If the line concentrator installation then switches to operating feed, one of the FETs is locked depending on the feed voltage polarity through modification of the potentials applied and the feed voltage is used only to operate the speech circuit. This circuit arrangement is simple to manufacture, has adequate dielectric strength and polarity independence. It is suitable for telephone stations with electronic speech circuits in line concentrator installations.

Title: Process for recovering waste heat from electric induction furnaces
Inventor: ISENHARDT FRIEDEL
IPC: F27B14/06
Filed: 1984-07-07
Abstract: The water normally used as a coolant for the coils wound from metal tubes of an induction furnace used for firing mouldings, for example so-called green anode compositions for the aluminium industry, is replaced by a synthetic heat transfer medium, for example by a eutectic mixture of diphenyl and diphenyl oxide (commercially known under the trademarks Diphyl or Dowterm A) with the purpose of recovering the heat radiated from the heated mouldings, as well as the Joule heat produced in the induction coils, in a relatively high temperature range and in an environmentally safe manner. According to the process of the invention, either the cold heat transfer medium entering the induction coils is drawn from a heat transfer medium circuit and the hot heat transfer medium emerging from the coils is admixed to the heat transfer medium circuit, or the heat to be recovered is transferred in a suitable heat exchanger to an identical or similar heat transfer medium.
Patent DE-3438056-A1 (DE)
Title: Switching point of a high-voltage switch
Inventor: PINNEKAMP FRIEDRICH DR
IPC: H01H33/24
Filed: 1984-10-17
Abstract: The switching point has an insulator, which is located in the open air, of essentially hollow-cylindrical construction. Located in the internal space of the insulator, which is filled with insulating means, are two switching elements (4, 5) which can move relative to one another along the axis of the insulator. The electric field which is present during switching off in the separating path (6) between the two switching elements (4, 5) is intended to be kept as low as possible, using simple means, on the outer surface which is exposed to the air. This is achieved in that the insulator is constructed from two insulating bodies. One (1) of these insulating bodies is constructed as a hollow-cylindrical supporting body. This insulating body (1) supports the other of the two insulating bodies on its outer envelope surface, in the region of the separating path (6). This other insulating body surrounds the separating path (6) in an annular form (attachment 9, cavity 10) and has a higher dielectric strength than air. <IMAGE>

Title: Ultrasound unit for generation of a thin emitted beam
Inventor: HASSLER DIETRICH DIPL ING
IPC: B06B1/08
Filed: 1984-12-10
Abstract: A 2-dimensional array (9) having a number of elementary ultrasonic transducers (10) is controlled by a control device (11) in such a way that a sound field is produced which corresponds to the focussing tube (5b) of a single large ultrasonic transducer (1). The data needed for control, that is, phase relation and emission level, of each individual elementary ultrasonic transducer (10) are calculated or determined experimentally. Thus, a long, sharp ultrasonic beam (5b) is generated directly on the 2-dimensional array (9); this avoids the disadvantages of a broad near field (5a). High scanning rates with high resolution can be achieved. By the omission of a broad near field (5a) the ultrasound unit can be made relatively narrow. For examinations a short distance under the skin it can be applied directly onto the body surface of a patient. A preferred field of application is transmission-based ultrasonic computed tomography. <IMAGE>
