Patent DE-2843482-A1 (DE)
Title: Single or multipole medium voltage switch - has main contact blade with lagging contact held in catching devices on fixed contacts
Inventor: HOLLMANN FRITZ
IPC: H01H33/12
Filed: 1978-10-05
Abstract: The switch is intended for use in an insulating gaseous medium. It consists for each pole of a rotatable single or double action isolator blade interacting with a fork-type fixed contact, and with a lagging behind contact in parallel with it. The lagging contact consists of at least one springy (steel) wire (10, 11) mounted at the point of the blade (6) rotation, or on the blade (6) itself. It interacts with a catching device on the fixed contacts, which holds it until the opening movement of the blade sharply pulls it out.

Title: Tunable active band-pass filter - has range changed using variable resistor and resistor network connected to its integrators and includes inverter
Inventor: SCHOENKE HERBERT
IPC: H03H11/12
Filed: 1978-10-28
Abstract: The bandpass filter consists of three operational amplifiers. Two are designed as integrators(20, 30) and accordingly have capacitors(C1, C2) whilst the third is designed as an inverter(10) and accordingly has a feedback resistor (14). The frequency of this filter is determined by two resistors(R1, R2). The first is connected between the output of the inverter and the input of one integrator, and the second between the output of one integrator and the input of the second integrator. The first resistor(R1) is a resistor network with given ratios(L:1.618) between its resistors. The second resistor(R2) is a variable resistor, to allow range of the filter the be changed over. The ratio between one setting of the variable resistor and the resistor network is 1:1.272.

Title: Melt electrolysis, esp. of water, releasing oxygen at anode - with addn. of lithium ions to increase current yield
Inventor: DIVISEK JIRI DR
IPC: C25B1/04
Filed: 1978-12-27
Abstract: In the electrolysis of a fluid melt, esp. water, in which O2 is released at the anode, Li ions are added to the electrolyte to increase the current yield. Pref. Li is added as hydroxide, fluoride, sulphate or carbonate, the amt. of Li added being min. 15 mole %, esp. in the case of an alkali hydroxide melt. The current yield is increased easily and release of water with the prod. gas is avoided. In an example, steam at normal pressure was electrolysed in a 1:1 NaOH/LiOH melt at 400 degrees C, using a Ni anode and cathode and a beta-alumina separator. The current yield was practically 100% of the theory, cf. ca. 98% without LiOH. At a current density of 400mA/cm2, the H2O/H2 molar ratio in the prod. gas was 8:1 cf. 20:1 without LiOH.

Title: Communication system control amplifier control range limiting circuit - uses two additional operational amplifiers connected to DC and reference voltage sources
Inventor: AICHHOLZ ECKART ING GRAD
IPC: H04B3/10
Filed: 1978-12-28
Abstract: To avoid error signalling in the carrier frequency when the non-linear region is reached the regulation or control zone is limited by stopping the control. To form the reqd. circuitry, two additional operational amplifiers (V1, V2) are used, to one of which a d.c. volt. is supplied on the input side in relation to the position of the regulating member. The d.c. volt. is proportional to the amplification factor. The ref. volt. source for the upper and lower control end positions is joined to the remaining inputs. The amplifier outputs are taken to the tapping point of a series-circuit consisting of two ohmic resistors (R1, R2) via normally-blocked diodes (D1, D2).

Title: Alarm system for buildings or vehicles - has magnet moved by lock cylinder to trigger reed relay contacts coupled to interlocked circuit
Inventor: GELHARD EGON
IPC: G08B13/00
Filed: 1979-02-23
Abstract: An alarm system for use with vehicles or buildings uses non contact sensors that may be used with a range of key operated locks. A bipolar relay is coupled to an alarm circuit and is controlled by an electronic interlock circuit consisting of two transistor cross coupled to provide a latching function. A third transistor provides the set and reset pulses for the latch. A door lock has an attachment that carries a permanent magnet on a moving arm that is used to trigger two reed relays in passing between the end positions. In this way triggering is independent of the arc of movement of the lock cylinder. A second interlock is provided by a pair of reed relay contacts. A pair of contacts may be used to detect windows that are not secured.

Title: Measuring lengths of cables, tapes, tubes and foils - using band on rollers with friction-dependent motor control
Inventor: ROELLE GUSTAV
IPC: G01B5/04
Filed: 1979-07-10
Abstract: A device measuring lengths of objects such as cables, tapes, tubes and foils achieves the required accuracy not attained by conventional measurement wheel devices because of wheel slip, measurement wheel tolerances etc. Slip is considerably reduced. For constant rotation speed it is completely eliminated. The wheel rotation counter system can be calibrated to compensate for mechanical tolerances. An endless measurement band (14) resting under pressure on the measurement object (6) surface passes around a guide wheel (13) and a measurement wheel (12). The measurement wheel rotations are sensed and used to control an indicator. A potentiometer (19) measures the frictional force between the object (6) and band (14) from the displacement of the measurement carriage (4) w.r.t. a guide (5) and controls the band drive motor (15).

Title: Window winding knob for motor cars - with hard inner and soft outer plastic shell
Inventor: KUMMER KARLHEINZ
IPC: G05G1/08
Filed: 1979-07-17
Abstract: The knob for the window winding mechanism of motor cars consists of a hard and wear-resistant core, e.g. polyamide. Its top part forms a ring with spokes to which an inner section of plastic material is injection moulded to embed the ring and the spokes. This material is pref. PVC with a Shore A hardness of 75.
