Title: Synchronisation of TV camera of video telephones - measures interval between a camera and central station frame synchronisation pulses
Inventor: GUNTERSDORFER SIEGFRIED
IPC: H04N5/073
Filed: 1977-04-22
Abstract: The telephones are interconnected for a conference with a picture of conference participants far away from each other combined in one picture reproduced on the screen of each subscriber. A central station (Z) measures different times of vertical deflection pulses (DBM2, BK2) between the respective camera (BF1) and the central station (Z) by counting pulses of a clock pulse generator (TG). A control signal (3) corresponding to the number of pulses at the beginning of the next full frame (BK2) is transmitted to the respective camera (BF1) in an empty line, and sets there a time (C1). The next frame synchronisation pulse (BK1) starts this timer (C1) which generates a new synchronisation pulse (BK1), from which on all following cycles, scanning and picture transmission processes of the camera (BF1) are measured. This synchronisation is repeated after each second full frame.

Title: Mains failure alarm circuit providing delayed acoustic signal - includes capacitor discharging via resistors and two alternately conducting transistors and buzzer receiving current from conductor
Inventor: GRATH GUENTHER DIPL ING
IPC: G01R19/155
Filed: 1978-12-21
Abstract: The circuit provides an acoustic signal upon failure of the mains supply and an optical display indicating the presence of the mains voltage. The acoustic signal is initiated upon mains failure via a capacitor (C2) discharging via two resistors (R5, R6). The discharge causes the transistor (T2) to switch into the blocking state after a delay interval. This causes a second transistor (T1) to conduct, so that current is supplied to the buzzer (Su) providing the acoustic signal. Pref. the acoustic signal is maintained within the voltage is restored, or it may be interrupted by actuation of a switch (S), which cuts off the current to the second transistor (T1), causing this to switch to the blocking state and the first transistor (T2) to switch to the conductive state. The switch (S) is then returned to its initial position (3), while the first transistor (T2) remains blocked. In specified switch position an incandescent lamp is ON, indicating the mains voltage restoration.

Title: Mfr. of solid poles for AC generators - using cold forming processes to pierce and press cylindrical work piece to finished dimensions
Inventor: WILHELM MANFRED DIPL ING
IPC: H02K15/02
Filed: 1979-04-20
Abstract: The process for forming solid pole pieces typically finds application in the manufacture of dynamos for motor vehicles. In the process the work pieces are accurately cut to length by sawing them off rom a round bar. No further machining operations follow, and no surface treatment of the work piece is employed to ease the cold deformation process. The work piece is first pressed to form a ring in each end face and leave a domed centre section. The ring depth and angle must be accurately maintained for satisfactory results. Both faces of the work piece (1b) are then dished (5a, 5b) resulting in a collar (9) round the dish edge and slightly concave cylindrical surface (6, 7). Choice of ring depth and angle have a significant effect on this deformation. The work piece (1c) is then pierced. The ensuring operations, which may employ an external matrix, are designed to produce exact external dimensions and a smooth bore.
