Title: Open circuit two wire voltage fault tester - uses two probes to indicate all faults in one test
Inventor: GUELK WALTER DIPL ING
IPC: H04B3/46
Filed: 1978-04-24
Abstract: The fault tester detects all voltage faults in an open circuit two wire telephone line in one test. A high threshold probe (SF1) determines the voltage between a combination of both wires (a and b) and earth (E). The low threshold probe (SF2) measures the voltage between the two wires (a/b) and between the single wire and earth (a/E, b/E). The thresholds are determined by the negative feedback loops (R5/R6, R7/R8). The high impedance voltage divider (R1, R2, R3, R4) has a symmetric earth (E) and conducts sufficiently to neutralise the line. R2 and R3 are of low impedance compared to the probes and the voltage divider. The threshold indicator (A) displays a voltage fault.

Patent DE-2832402-A1 (DE)
Title: Relay responsive to AC signal - uses capacitor charging current and push pull amplifier to inhibit erroneous operation
Inventor: MOOK BRUNO
IPC: H01H47/32
Filed: 1978-07-24
Abstract: The relay operating coil (12) is connected via diodes at each end to one terminal of a capacitor. The other terminal is joined to the output of a push pull amplifier using a complementary pair of transistors. If an AC output signal is present the capacitor charging current gives the relay current. If there is no AC signal, the charging current ceases and the relay drops off. There is therefore, no continuous response to a short time distrubance which triggers the transistors erroneously. A typically application is supervision of the colling water pump speed in X-ray equipment.

Abstract: The digital/analog converter is designed to operate using both the A-law and the mu-law. In the case of the mu-law, all bits in the digital signal are inverted and specified code words are constructed and added to n bits of the digital signal. A coder isused which employs the interativeprinciple so that at the network ends a constant current source may be applied to a section of the character recognition signals when the intervening stages are at a binary zero value.
Patent DE-2842328-A1 (DE)
Title: Receiver for isochronous binary modulated signals - counts samples per signal, decides whether sufficient samples have been taken and carries out further scanning steps to detect distortions
Inventor: PREY GERHARD
IPC: H04L25/40
Filed: 1978-09-28
Abstract: The receiver automatically increases the sample counter by an integral multiple of steps for each smaple of the signal, whenever the number of samples per signal is inadequate due to isochronic distortion. The quotient of the needed number of sample steps and the actual number os such steps per signla is generated for a given isochronic distortion. Information is transferred only when the sample counter has a given specified count. Since the check requires a sufficient synchronism between sign flow and counter, a fictitious scanning raster has tobe formed between two actual scanning points.

Title: Seat belt tautness relaxing device - uses local flexible enlarged portion on belt working together with tensioned pair of rollers
Inventor: HESSENBRUCH ROLF DIPL ING
IPC: B60R22/19
Filed: 1978-12-18
Abstract: The seat belt system is fitted with a device which relaxes the tautness of the belt and reduces the pressure of the belt on the user's body. The device is built into the diverting fitting assembly (3) and consists of rollers (6) and (7) kept under constant tension against each other by elastic loopes (8) while stop lugs provided between the two rollers maintain a ga between the two rollers equivalent to the thickness of the belt webbing. At a suitable point the webbing is provided with a section (9) of enlarged thickness, which stops the belt movement when the enlarged section arrives at the pair of rollers provided the belt is being pulled at slow speed. However the sudden pull following a sudden deceleration is strong enough to overcome the pressure by the rollers on the thick section while the elastic loops (8) expand momentarily.
