Patent DE-2804787-A1 (DE)
Title: Brushless DC motor with field sensor - has sensor offset in direction of rotation and special pole shaping giving offset interpolar gap
Inventor: MUELLER ROLF DIPL ING DR ING
IPC: H02K29/08
Filed: 1978-02-04
Abstract: The brushless DC motor comprises an external circular permanent magnet stator and wound rotor mounted on the motor shaft. In a space between rotor laminations and one end plate of the stator housing, a magnetic sensor, such as a Hall device, is placed. The sensor is positioned so that it is in the region of two adjacent but unlike poles of the stator. The sensor is offset by an angle from the centre of the space between poles in the direction of rotation. In addition, the section of the rotor pole which acts on the sensor is so shaped at the outer edge of the interpolar gap that it is offset by an angle in the direction of rotation. The latter offset angle is made greater than the sensor's offset angle partic. in the case of high-speed motors having square-loop stator magnetization.

Title: Transmitter search run circuit in superheterodyne receiver - has run carried out at certain frequencies at slow speed so as not to miss transmitter signal
Inventor: HARASZTI IBOLYA DIPL ING
IPC: H03J7/28
Filed: 1978-03-23
Abstract: The search run is performed automatically by the radio receiver. It is carried out after its start at such a slow speed, that a transmitter signal to be received is not lost after recognition in spite of a signal presence in an adjacent channel. The time for the slow run is sufficient for running over at least one channel. If during the slow run no transmitter signal is found for tuning in, the run is continued at a higher speed. The received frequency varies according to a control voltage.

Patent DE-2816093-A1 (DE)
Inventor: FAHRENSCHON FRANZ DIPL ING
IPC: H04Q3/545
Filed: 1978-04-13
Abstract: Customer and program data may be amended in telephone systems only by authorised persons in a central remote management station (FV). Since the data are intended to be transmitted via normal telephone lines, these lines must be particularly well protected against unauthorised access. To achieve this, a connection is set up by the remote management station (FV) to the equipment in the customer's system which is intended to carry out the amendments. Once this connection has been cleared down, the customer's equipment (SMS) independently sets up its own connection to the remote management station. Only after an identification procedure are the amendment data retrieved step by step and acknowledged (SFV) and only after the contents of the control memory (DSP) in the customer's system have been amended is an amendment report prepared in the remote management station (FV). <IMAGE>

Title: Automatic control of cross=section profile of rolled strip - via electronic circuit which accurately adjusts tension across strip leaving hot or cold rolling mill
Inventor: TSCHABANOV ALIM IVANOVITSCH
IPC: B21B37/38
Filed: 1979-08-08
Abstract: On the exit side of a rolling mill are pairs (11,12) of rolls running on only part of the top and bottom surfaces of the strip, and applying tension to the latter. Each pair of rolls is driven by a motor with a tachogenerator and synchro. The result is that electric signals, representing the actual strip tension and the angular position of rolls can be fed into a strip tension controller in an electronic comparator circuit. The result is that the tension can be adjusted across the width of the strip, so that flat strip free from barrel profiles or undulations can be obtd. The electronic circuit is pref. also connected to the hydraulic profile controller (10) for the work rolls (3) in a 4-high mill.

Title: Ultrasonic distance measurement appts. - has velocity correction system which uses extra transducer to monitor fixed reference path length
Inventor: MAGORI VALENTIN DIPL PHYS
IPC: G01S7/52
Filed: 1979-08-30
Abstract: The height of loose material (6) on a conveyor belt (5) is measured by ultrasonic transducers (1,2,3) which radiate short pulses in a narrow beam (11,21,31) and receive the reflected pulses from the material. The measurement is subject to error because velocity of propagation varies with temp. and pressure and there may be a velocity gradient due to moisture in the material. Velocity error is corrected by an extra transducer (4 or 4') which measures the delay time over a reference path (41 or 41') to a fixed reflector (40 or 40'). The position of the reference path is chosen to have as nearly as possible the same propagation conditions as the measurement paths (11,21,31) without being disturbed by loose material flying about.
