Title: Detachable pipe connection with rubber sealing ring - engaging with rib on socket inner wall and gripping spigot
Inventor: WEDEKIND GERHARD DIPL ING
IPC: F16L21/03
Filed: 1979-06-07
Abstract: A pipe end, the wall of which tapers inwards towards its end face, is pushed into the widened out socket of a second pipe end which holds a sealing ring of natural or synthetic rubber, to form a detachable joint. The sealing ring has an axial, sectional extension, which engages over a retaining rib running round the inner circumference of the socket end. The cross-section of the sealing ring has, in the assembled condition, a deformed inner contour, which is contacted over its whole surface, in parallel, by the tapering outer mantle of the spigot pipe when it is pushed in. As the spigot is pushed into the ring, the axial extension is pressed into a groove in front of the holding rib, and the thrust of the ring ensures the holding of the joint irrespective of the degree of axial force exerted on it.

Title: Subscriber line checking circuit in electronic telephone exchange - has low pass filter to eliminate power frequency interference with capacitance values chosen by selector
Inventor: LECHNER ROBERT DIPL ING
IPC: H04M3/22
Filed: 1979-09-26
Abstract: The condition of the line between the subscriber and the relevant terminal circuit at the automatic electronic exchange is cyclically checked. The purpose is to ensure that there are no faults, and to recognise if the subscriber is connected or is calling for the connection. The state of individual lines is monitored in groups using selector switches to connect each subscriber terminal in turn to detectors. These check the line for high or low impedance and for a ringing tone. In order to eliminate the effect of interference from power circuits inducing alternating voltages in the lines which could result in, for example, recognition of a high impedance state when in fact the circuit is low impedance, a filter is incorporated. The filter comprises an RC circuit in which the capacitance values are chosen by a further selector to give the correct tuning for the individual line being checked.

Patent DE-3032474-A1 (DE)
Title: Sliver feed control - has two sliver length monitors to determine action of each other for more accurate feed
Inventor: WOLF HORST DIPL ING
IPC: D01H13/24
Filed: 1980-08-28
Abstract: An additional length measurement unit is provided in the sliver feed, so that the two length measurement assemblies lie in parallel to each other. The signal from each unit releases the operating switch of an indicator and also overcomes the operating switch of the indicator. Specifically the operation of the indicator is delayed by a time scale and sliver delivery length. An additional pulse generator and pulse counter operate independently of and parallel to the primary pulse generator and counter. The contacts tripped by the pulse counters are in series in the machine drive current path. As the contacts in the current path are opened, each counter gives a delayed contact closing action in sequence, while the other counter opens the contact of the other delay unit. The delay unit is a timer or a sliver length monitor, connected to an indicator which starts after the delay time. A NAND element is placed between the outputs of both pulse generators, connected to the alarm indicator. The adjustment units for both pulse counters are coupled to each other. As one unit monitors the action of the other, then sliver length delivery is brought to greater accuracy, and the probability that the machine is not stopped in time is reduced.
