Title: Self-monitoring inductive proximity switch - monitors moving parts of machinery and has damping sensing coil to test own functioning
IPC: G01V3/11
Filed: 1980-03-01
Abstract: The switch has its own self-testing or self-monitoring circuitry to check its functioning. This circuitry contains an electrically-switched oscillation damping circuit. The oscillator contains an induction coil which is short-circuited by the damping circuit. Only that part of the coil lying between a tapping and one end is short-circuited. This is accomplished using a transistor switch in the damping circuit. The transistor's collector is coupled via a resistor to the tapping and its emitter is connected to one end of the coil, which is also coupled to one supply pole. The transistor's base is connected via a resistor to a test switch. The test switch applies the opposite supply pole to the transistor's base, thereby turning it on and shorting out part of the coil. A filtering capacitor is connected into the transistor's base/emitter circuit.

Title: Turn indicator repeater light for motorcycle - uses relay and dual resistance path to reduce intensity if machine is stopped or moving at low speed
Inventor: KRAMHOELLER RICHARD
IPC: B60Q1/00
Filed: 1980-06-26
Abstract: The indicator lamp (7) is controlled by a transistor (8) switched by the pulses (J) from the blink generator (1). When the vehicle is in normal motion the limiting resistor (9) in series with the transistor base is chosen with a value which gives a bright light from the lamp. The resistor can be photosensitive and automatically adjust lamp brilliance to ambient light conditions. At rest or low speeds a relay (11') changes the blinker unit (1) output to a path with greater resistance (10,9') and the lamp gives a lower illumination. The system gives a bright warning to the driver when the turn indicator is on during a journey, and a reminder, at a lower level, if he has forgotten to switch off after stopping the motor-cycle.

Title: Method for determining the state of discharge of an electrical accumulator and circuit arrangement for carrying out this method
Inventor: HORN LUTZ DR ING
IPC: G01R31/36
Filed: 1981-04-21
Abstract: The discharge state or the energy still stored in a lead accumulator is to be measured. A measure of this is the acid density in the discharge zone of the positive plates. The acid density can be determined with adequate accuracy by measuring the open-circuit voltage. According to the invention, a monostable multivibrator (15) is started under open-circuit conditions. At the same time, the open-circuit voltage is measured and transformed into pulses in an analog/digital converter (7). These pulses and the pulse of the multivibrator (15) are applied to an AND gate (8). The output signal of the latter is measured by means of a digital counter (10). This counter is calibrated in units of acid density or, respectively, the capacity still available. The invention is used in traction batteries installed on vehicles. <IMAGE>

Patent DE-3116576-A1 (DE)
Title: Method for operating a digital audible tone generator
Inventor: GIEBLER HANS JUERGEN ING GRAD
IPC: H04Q11/04
Filed: 1981-04-27
Abstract: In a digital audible tone generator, a group of PCM words is in each case allocated to a frequency or frequency mixture, the number of PCM words within a group corresponding to the amplitude values of a complete sinusoidal wave or an integral multiple of a sinusoidal wave. The memory spaces which contain the PCM words are activated consecutively by a counter which generates the activation addresses. For distortion-free generation of a sinusoidal wave in the subsequent digital/analog conversion, it is required that the last PCM word in a group must in each case have the amplitude value "zero". If the PCM words in a group are checked for the presence of the amplitude value "zero" before being recorded in the memory and, if this value occurs except in the last PCM word, it is changed to a value which differs from the amplitude value "zero", the end of a group can be easily identified by the occurrence of the amplitude value when the memory is read out.

Title: Heat exchanger for heating systems
Inventor: SCHARNWEBER PETER
IPC: F24D19/10
Filed: 1981-05-07
Abstract: The invention relates to a heat exchanger for heating systems. Arranged in the tube system between the heating boiler and stack is a heat exchanger which has in the interior a tube spiral through which heating water flows. The heat exchanger has connecting stubs/pieces for the existing tube system. Simultaneously arranged in the upper stub is a closing damper/butterfly valve which is controlled by a positioning motor/servomotor. The positioning motor operates in dependence on the flame in the boiler. The rate of flow of the water in the tube spiral is determined by a pump situated in the inlet of the heat exchanger. This pump is controlled by a temperature sensor which measures the exhaust gas temperature at the stack end and the water temperature in the tube spiral. The water heated in the heat exchanger is fed to the water circuit of the existing heating system. The inlet takes place in the boiler intake, so as to achieve less vigorous ignition of the boiler flame.

Title: Extraction process and plant for carrying out this process
Inventor: STRAUSS KUNO DIPL CHEM DR
IPC: A23L27/10
Filed: 1981-08-20
Abstract: An extraction process is described, in which material to be extracted is brought into contact with a supercritical carrier gas and in the loaded carrier gas, by changing the parameters of state, a phase separation then takes place into extract and non-loaded carrier gas. The material to be extracted is combined with the carrier gas at a pressure matched to the carrier gas pressure, force-mixed with the supercritical carrier gas in a continuous feed stream, after which the carrier gas enriched or loaded with the extract is separated off from the residue of the material to be extracted, which residue is continuously discharged from the carrier gas circulation. With the process and with the plant for carrying out the process, it is possible to subject to the extraction process the most varied types of substances, which differ considerably with regard to their composition, in one and the same plant and with extremely short changeover times. It is further possible with the process to carry out a fractional extraction so that different extracts can be specifically dissolved out from the material to be extracted. The plant operating according to the process permits specific interventions in the extraction process at many places so that it is also possible, for example, by using automatic process control, to operate the plant according to a mixed target spectrum of the various extracts.
