Patent DE-3721898-A1 (DE)
Title: Signalling speed indicator (speedometer) for motor vehicles
Inventor: SCHATTA MARTIN
IPC: B60Q1/54
Filed: 1987-07-02
Abstract: Signalling speed indicator for motor vehicles, which is chemically welded together with its consoles (5, 6) to the radiator bonnet (hood) or the roof superstructure. It consists essentially of a signalling element (1) designed in accordance with the laws of flow and also aesthetically shaped from plastic and whose surface is metallised and/or luminescent. In terms of functioning, the force of the resistance of the slipstream (relative wind) is greater from 50 to max. 60 km/h than the constant cohesive force of the permanent magnets (3, 4). The further tracking movement of the signalling element (1), which is rotatably mounted in the spring hinge (7), is stopped by the spring tongue holder (2) or the like until a driving speed of higher than 60 km/h is reached. The vertical 90@ signalling element position goes over to a recumbent horizontal position - and vice versa. In order also simultaneously to permit acoustic signalling in addition to such tolerated vertical optical signalling, a known tubular signalling whistle (9) of acceptable volume is arranged in the respective signalling element (1). In terms of functioning, the signalling whistle (9) can be heard only in the 50-60 km/h region because of its angular positions. <IMAGE>

Title: Recirculating ball screw
Inventor: BUSCHULTE JOACHIM DIPL ING
IPC: F16H25/22
Filed: 1987-09-17
Abstract: The intention is to provide a recirculating ball screw which can be used, in particular, for robotics and handling technology but also, more generally, in the construction of machine tools, for NC-controlled linear axes while requiring relatively little expenditure on production and expenditure of space. This is achieved by the formation in a spindle nut (2) of at least one circular ball recirculation track (3) arranged eccentrically and parallel to the threads (7) of the screw. In one area, this ball recirculation track approaches a thread (7) of the screw (1) tangentially to form an area of power transmission between the thread (7), the balls and the spindle nut (2). <IMAGE>

Title: Arrangement for testing interturn faults and the insulation of inductor coils
Inventor: SCHMID ALBERT
IPC: G01R31/06
Filed: 1987-09-29
Abstract: In an arrangement for testing interturn faults and the insulation of inductor coils by means of resistance comparisons between a test piece, which is to be connected to the secondary winding of a first transformer connected to a supply voltage, and a standard, which is to be connected in the same way to this secondary winding, the primary winding of the first transformer is optionally connected via an inverter, known per se, to a battery or via a rectifier and a second transformer to a mains supply source. For testing interturn fault test pieces of different resistance values, the secondary winding of the first transformer is provided with several tappings with switch contacts, and for testing insulation test pieces with different resistance values of the secondary winding of the first transformer, a Greinacher circuit, known per se and connected to it, is connected downstream via switch contacts to a plurality of insulation test leads. A voltage meter is provided between two specific tappings. The primary winding of the second transformer is connected to the mains supply voltage separately from the measuring bridge.
Patent DE-3737215-A1 (DE)
IPC: C04B41/87
Filed: 1987-11-03
Abstract: An electrochemical sensor for measuring the oxygen content of gases, in particular exhaust gases from internal combustion engines, comprises a solid electrolyte of zirconium dioxide and/or other oxides which conduct oxygen ions and at least one electrode arranged on the side of the solid electrolyte exposed to the gas to be measured. The electrode(s) may contain  a ceramic supporting skeleton and the electrode(s) exposed to the gas to be measured is (are) covered with a porous ceramic protective coating of an Al2O3- and/or Mg spinel (MgO.Al2O3) matrix in which preferably metastable ZrO2 particles are embedded. The use of a mixed oxide system of Al2O3/ZrO2, which may contain a stabilizer for the ZrO2, and which is preferably obtained by coprecipitation or by combination of suspensions of separately precipitated components or by spray calcination of a common solution of salts of the components, makes it possible in a surprising way to obtain a sintered adhesive protective layer with a relatively narrow pore size distribution which allows the optimal passage of gas to the outer electrode of the sensor. The use of the Al2O3/ZrO2 mixed oxide powder also makes it possible to compensate to a very large extent for the previously observed disproportion between the mechanical stresses and the adhesive strength of the layer and to obtain the desired porosity and regulating position of the sensor.

Title: Single-stage 4:1 multiplexer for RZ signals
Inventor: MEYER FRITZ DR
IPC: H03K17/60
Filed: 1988-03-10
Abstract: High-speed multiplexer for the time division multiplexing of four RZ-format digital signals present on separate input terminals with bit repetition rates of several hundred Mbit/s. Compared with known multiplexers, the multiplexer according to the invention is intended to be constructed without multi-emitter transistors and other components whose dimensioning is critical, and furthermore the construction is intended to be inexpensive. The multiplexer according to the invention comprises an emitter-coupled differential amplifier, to which four amplifier stages in an emitter circuit and two amplifiers in a basic circuit are connected in cascade in a totally symmetrical arrangement. The amplifier stages in the emitter circuit are in each case connected to one of the input terminals for the digital signals to be combined, whereas a clock signal and the clock signal shifted through 180@ in relation to it are applied to the base terminals of the emitter-coupled differential amplifier. <IMAGE>

Title: Casing-current reduction
Inventor: KARRENBAUER HERBERT DR
IPC: H02G5/06
Filed: 1988-08-10
Abstract: In the case of single-pole encapsulated fully-insulated switchgears, the problem arises that a strong casing current is induced in the encapsulation and leads to losses and undesired heating. The casing current can be prevented by electrically separating the encapsulation parts from each other using insulation pieces. This can, however, cause voltage peaks which result in arc discharges and damage in the secondary system. In order to avoid these disadvantages, the invention provides for the encapsulation parts to be electrically connected with each other via a resistor, the resistance of the resistor being at least high enough for the back-current induced in the casing to be limited to a value at which it no longer causes any noteworthy loss and at most has such a value at which voltage peaks are limited to an extent which is harmless for an economically viable insulation. <IMAGE>

Title: Image transmission system
Inventor: KANAO SHOZO
IPC: H04N19/60
Filed: 1989-03-02
Abstract: Image transmission systems are known which transmit an existing data-compressed image in digital form via a telephone line. The digital image information is expanded in the receiver and reproduced on a screen. The transmission channel is blocked for voice transmission during the period when the image is being transmitted. To reduce the transmission time, the compressed digital image information is converted into an analog signal in a D/A converter and is transmitted in a modulated manner via the transmission channel. In the receiver, the incoming signal is demodulated and supplied to an A/D converter. The digital image signal now present is expanded and supplied to a screen by a D/A converter. The invention can be used for transmitting images by a narrow-band transmission channel. <IMAGE>
