Patent DE-2437300-A1 (DE)
Title: Drive for precision angular indexing - uses toothed cams to convert intermittent linear motion to rotation
Inventor: BROWN DAVID E
IPC: F16H27/02
Filed: 1974-08-02
Abstract: The cover (4) is bolted to the internally toothed ring (2) and to the flanged ring (3) so that it is retained by the flange (20) of the housing (1) but is still free to rotate. When the rod (5) is pushed upwards it lifts the disc (9) until the teeth (42) contact the teeth (38) of the disc (6). The disc (6) has peripheral teeth (36) which slide in the teeth (35) of the ring (2) and end teeth (38) which normally engage the teeth (37) of the fixed ring (8). Further upward motion of the rod (5) lifts the disc (6) clear of the ring (8) and then causes it to rotate together with the ring (2). Downward motion of the rod (5) allows the teeth (38) and (37) to reengage in a different angular position.

Title: Friction welding pipelines together - using external annular projections so a smooth bore is obtd.
Inventor: BRAITHWAITE ARTHUR BEVAN MIDGL
IPC: B23K20/12
Filed: 1974-12-05
Abstract: In this process of joining two hollow parts, each part is provided with an annular groove on the end surfaces which are to be welded together; due to this groove, the end surfaces consists of two coaxial rings and the outer ring on both parts e.g. tubes, projects so that, at the start of welding, the two outer mating surfaces are upset in the welding process the material can expand into the groove until the two inner surfaces come into contact, this contact terminating the process. The welded joint and the inner contact surfaces can be in the same plane or offset w.r.t. each other. The method is esp. applicable to welding tubes for under-sea pipelines. No upsetting occurs in the bore of the tube, the result being that a smooth, aligned bore is obtd.

Title: Phase control for magnetic tape recorder - comprises tape head with reference vertical sync. signals and on correct phase relation switches to compare horizontal sync. signals
Inventor: ILMER ANDREAS DIPL ING
IPC: H04N5/782
Filed: 1975-10-31
Abstract: The phase control, for a magnetic tape recorder, derives a control signal for the head drum's drive circuit (3) by comparing the vertical sync. signal (2Vr) from a reference source with the output signal of the tachogenerator (4) coupled to the drum drive. When these two input signals bear a given phase relationship to one another, a signal is sent to an electronic switch (2) between the comparator output and the drive circuit. The switch connects the output of a second phase comparator (7) to the drive circuit. The second comparator compares the horizontal sync. signal (Hr) from a reference source with the horizontal sync. pulses (Hb) obtained from the tape.

Title: Linear temperature resistance circuit for central heating control - utilises transistor linear base-emitter voltage variation with temperature
Inventor: KALNY FRIEDRICH ING
IPC: G01K7/01
Filed: 1976-02-11
Abstract: Thermo-resistive elements used for temperature sensing for central heating systems require linearising circuits which reduce operating range and sensitivity. These problems are overcome by using a transistor in which the base-emitter voltage variation is linear with temperature. Air temperature is sensed for the control of central heating systems by a transistor whose collector-emitter junctions are exposed to the air temperature. The transistor base is connected to a resistive (4) potential divider connected between the collector and emitter. The resultant circuit resistance varies linearly with temperature and consists of the collector emitter resistance of the transistor. A full wave diode bridge circuit connected to the circuit renders it independent of supply voltage polarity.
