Title: Synchronising gates for digital data signal receiver - has circuit to ignore jitter but correct systematic error, by making counter jump one clock cycle
Inventor: ZEMANEK JOSEF DIPL ING
IPC: H04L7/033
Filed: 1979-05-08
Abstract: A synchronising signal (e4), for receiving a 256kBit/s data signal (b), is derived from a 4.096MHz clock (a) by a 4-stage counter (e1, 2, 3, 4). Three gates (f, g, h) are also generated. The 'synch correct' gate (g) is wide enough, e.g. 2 clock cycles, to accept allowable jitter. The immediately adjacent 'late' (f) and 'early' (h) gates are 1 clock cycle wide. A pulse (c) derived from the incoming bits (b) is fed to the three gates and the outputs analysed by a logic circuit. With no outputs, the counter is reset by the next pulse (dotted line, LHS). Two successive outputs from the late gate (f) make the counter jump 1 clock cycle, similarly the early gate (h) makes the counter miss a cycle. Nothing happens while the pulse is in the synch, correct gate (g).

Title: Light emitting diode control circuit - has emitter-follower, with transistor at input end to prevent excessive increase in collector current for each alternation of control signal
Inventor: SEINECKE SIEGFRIED DIPL ING DR
IPC: H04B10/50
Filed: 1979-06-06
Abstract: The control circuit for regulating the light emission from a light emitting diode (LED) uses a binary control signal at the input (SV). The diode is in the collector circuit of a transistor (T) forming the output stage. A resistance (R1) connected to the base of the transmitter is in parallel with a further resistance (R7) and a capacitor (C3). This forms an emitter follower arrangement with a further transistor (T2) towards the input end, which has a resistance (R2) connected between its emitter and the power supply (V2). This arrangement prevents an excessive increase in the collector current (iD) each alternation of the control signal. An additional circuit controls the input signal which can vary in amplitude and length, maintaining a square waveform for the control pulses.

Title: Rotor balancing system with successive stages - combines polar and coordinate mass compensation for large out-of-balance forces
Inventor: BIEHL HARALD
IPC: G01M1/22
Filed: 1979-11-19
Abstract: Balancing is effected in two separate stages, the first involving weighting the rotating rotor to compensate out-of- balance forces and the second stage involving removal of material. The second balancing stage is effected at an angle to the first, e.g. of 45 degrees. The first balancing stage uses polar mass compensation at one or more balancing points, to rectify a large amount of out-of- balance force, with the second stage using component mass compensation. The intersection point of the two component axes is dependent on the angular balancing position for the polar mass compensation. Pref. the rotor imbalance (UA) is initially connected by two weights attached at spaced angular points (P1,P2). The residual imbalance (UR) is then compensated by removing material at points along coordinate axes (K1,K2) offset by a given angle from the first two points (P1,P2).
