Patent DE-2812473-A1 (DE)
Title: Permanent magnet electric motor - operates with DC pulse transmitter breaking magnetic attraction between two poles
Inventor: NAGEL WILHELM FRIEDRICH
IPC: H02K53/00
Filed: 1978-03-22
Abstract: An electric motor with a stator, assembled from a spider of permanent magnets, is surrounded by a rotor, consisting of eight planets, each assembled from a spider of permanent magnets. The rotary motion is maintained by cyclic d.c. pulses which break the magnetic attraction of one group of poles. This motor operates with a very high efficiency and needs a minimum of external energy. The stator is made up of eight groups of permanent magnets (14), each with a steel shoe (15). Each of the rotor planets consists of a spider (26) with four permanent magnets (20) and steel shoes (21). A DC pulse transmitter (8) is electronically controlled to break the magnetic attraction between two poles and cuase the rotor to revolve. This motion is transmitted by spur gearing to an output shaft.

Title: Acoustic traffic crossing aid for blind persons - has traffic light condition signalled by buzzer generating two separate sounds
Inventor: IPACH WOLFGANG
IPC: G08G1/005
Filed: 1978-04-18
Abstract: An aid for blind persons at traffic crossings utilises acoustic signal generators to distinguish between red and green conditions. The traffic light system (A) has an associated selector with a raised symbol indicating the direction of passage required. The safe crossing condition is signalled by a continuous note emitted by a buzzer, whereas the stop condition causes an intermittent signal to be generated. Each traffic light located on a corner has two such selectors; one for each direction.

Title: Electrically conductive mixed oxide prodn. by reactive spray drying - of mixed oxide of lanthanum with manganese, nickel, or cobalt contg. chromium and small amts. of other metal cations
Inventor: SCHMIDBERGER RAINER DR
IPC: H01M8/0215
Filed: 1978-06-03
Abstract: Prodn. of electrically conductive oxidic material (I) for application at high temp. and in a wide range of O2 partial pressures involves adding small amts. of Cr and mono- or di-valent alkali, alkaline earth, Zn, Cd, Mn, Sn and/or Pb cations to mixed oxides with perovskite structure based on LaMnO3, LaNiO3 or LaCoO3. A soln. of the cations in the exact stoichiometric ratio is sprayed into a hot reaction tube at 1000-1500 K, together with or with injection of the O2 needed for the reaction, and the solvent is vapourised. The non-volatile constituents pass through the tube, where the desired (I) with homogeneous distribution forms in the hot reaction zone, and the powder is deposited in a cyclone, the solvent vapour being removed. (I) is useful in electrochemical high temp. cells, esp. fuel cells, and for supplying current under conditions of high temp. (hot conductors, probes etc.) and in reducing or varying gas atmos.

Title: Ultrasonic transceiver signal echo profile writing circuit - uses intermediate memory and RAM in conjunction with logic circuits to produce echo modulation signal to superimpose on TV screen picture
Inventor: DOBRITZ GUENTER DIPL ING
IPC: G01S7/52
Filed: 1979-02-09
Abstract: The echo profile writer incorporates a RA, (1) with row and column decoders, respectively connected to dividers (14, 18), the column (n:1) divider being backed up by a another divider (19). The latter and the input memory stage (2) are controlled by the same oscillator (20). A logic circuit incorporating an OR-gate (15) and two AND-gates (16, 17) directs p(n-1) pulses into the appropriate decoders, p being the number of rows and n the number of columns. The input signals enter from a ultrasonic transceiver (3) through flip-flops (4, 5) to the buffer memory (2), prior to entering the RAM (1). The output goes to a modulator (30) which superimposes a signal on the picture synchronisation signals (26-29). The circuit is able to eliminate regular echo patterns (e.g. sea-bottom, ship hull) and write only a recently-received echo (e.g. fish shoal) onto the picture screen.

IPC: G01N11/10
Filed: 1979-03-08
Abstract: The process is intended for detecting the characteristic of a substance pertaining to its viscosity, consistency, pliability etc. important for its flow and spreading properties. A measuring body is passed on a preset path at a given velocity without external prompting. The maximum force exerted on the measuring body is detected as a rate for the substance viscosity or consistency. The process is carried out in a device which has a specimen container, a drive for moving the measuring body into and out of the container, or through the substance, as well as with a dynamometer on the measuring body. The latter is pref. in the form of a sphere coupled to the dynamometer by a shaft. The specimen container may be adjustable in height, forwards and backwards along the rotation path of the sphere. The shaft may be of considerably smaller diameter than the sphere. The dynamometer may have a pull-type indicator.

Title: Three=phase supply protection circuit - has current converter connected to unit with filtering, rectifying and delay stages operating relay
Inventor: RUF DIETER DIPL ING
IPC: H02H3/33
Filed: 1979-06-15
Abstract: The overload protection circuit for a three phase supply has a summing current converter which may be a frame converter for holding a set of conductor rails. This is connected to an evaluating and cut-out unit with a relay followed by a device for converting the secondary current of the converter into a voltage which is amplified and from which the h.f. component is filtered out. The filtered signal is compared with a reference value after rectification. The rectified signal is used as a logic signal and passed through a delay storage with a delay period corresponding to at least half the frequency of the supply, to obtain a constant logic signal. This is used to trigger a further delay stage to operate a relay after the delay period, to cut-off the fault current. The second delay stage can have its delay continuously varied or in stages by a programming device.
