Title: Synchronisation system for data protection - selects correct data-correcting syndrome using up=down counter and logic
Inventor: MARKWITZ WERNHARD DIPL ING
IPC: H04L1/00
Filed: 1978-10-18
Abstract: The synchronisation system has an up/down counter(Z1) disabled when two syndromes are the same and enabled when the two are not the same. One of the syndromes is used for correcting the data. The up or down direction of the counter is selected depending on the binary value of one of the syndromes. When a given first or second count state is reached a signal is released that indicates the correct syndrome. This signal controls a flip-flop(K) that indicates the correct syndrome by producing an output signal which is used to initiate the correction of the data using the correct syndrome. A parity stage receives both syndromes and passes a parity signal to an AND-gate which also receives clock pulses. The AND-gate's output is connected to the counter's input.

Title: High-frequency tube seam welding - with heat input control by measuring welded seam width or temp.
Inventor: NICOLAI FRANZ ING GRAD
IPC: B23K13/08
Filed: 1978-11-21
Abstract: During the high-frequency welding of seam welded tubes the electrical power input, edge compression force and strip velocity are measured. At a constant welding roll pass, the welding power input is automatically controlled as a function of the measured width of the welded seam. This system results in an improved quality of the welded seam which is maintained throughout the opertion. A strip is bent to a tube (1) by the concave rolls (2). The width B of the welded seam (3) is measured without contact by the optical unit (4). This feeds a controller (7) and adjusts the regulator of the high-frequency generator (6). If manual control is desired instead of automatic control, the switch P is changed over to the manual control (8). In another version, the width measurement is used to control the pressure of the rolls (2) and the high-frequency input is controlled by a measurement of the weld temperature.

Title: Mass spectrometer system with ion filter or analyser - involves slower shift of given mass range with rising mass and under retarded measuring period
Inventor: DOBBERSTEIN PETER DR
IPC: H01J49/26
Filed: 1979-06-23
Abstract: In the system an ion source generates ions of different mass, which are supplied to a controllable filter, or analyser, for passing only ions whose mass lies in a preset range. The intensity of passed ions is measured, and possibly indicated. The preset range is more slowly shifted, with delay of measuring time period, with increasing mass. The appts. for this system uses a four-pole as the ion analyser, behind which is connected the detector for ion intensity of a given range at the analyser output. Possibly a secondary multiplier is incorporated between the detector and analyser. A h.f. voltage generator supplies the analyser with an a.c. voltage' to which a d.c. voltage is superimposed. The generator has a control unit, while a data processor deals with detector signals, concerning the ion intensity. The control unit provides a non-linearly variable control signal.

Title: Electronic analogue to frequency converter range adaptation circuit - controls signal input rate and frequency generator division from input
Inventor: SCHEEW PETER
IPC: G01R21/127
Filed: 1979-07-20
Abstract: An analogue-to-frequency converter circuit for measurement value sensing or conversion operates an analogue values singly or as products. It automatically adjusts the measurement voltage to the operating ranges of the electronic components in the converter whose offset voltages and drift are negligible compared to the useful signal. It eliminates the complexity and expense of conventional circuits and the errors associated with load resistance switching. The measurement signal is periodically switched to the converter filter at a frequency dependent or a range selector operating according to the signal level. The range selector controls the division of a frequency generator output via two frequency divider stages so that the relationship between the output frequency of the analogue-to-frequency converter and the measurement parameter remains constant.
