Patent DE-2717634-A1 (DE)
Title: Analogue meter with instantaneous value indication - uses sample and hold circuit controlled by pulse generator constructed as monostable flip=flop
Inventor: KARLICEK WERNER
IPC: G01R17/04
Filed: 1977-04-21
Abstract: The analogue meter with instantaneous value indication consists of a standard measuring head or transducer (3) whose signals are fed to a matching amplifier (6). The output of this is fed to a conventional sample-and-hold circuit (5). The output of this circuit is taken to a converter (2) which drives a conventional moving-coil meter movement (1). The control input to the sample-and-hold circuit is fed from a pulse generator (8) which is controlled from a decoupled trigger (9). Isolation is via an opto-coupler (11). The pulse generator is constructed as a monostable flip-flop with control provided by a timer (12). Further control can be obtained by means of a light-emitting diode (15) on the output of the flip-flop. This can be integrated with the opto-coupler.

Title: Detector for seismic investigation, esp. under amphibious conditions - combines pressure sensitivity with detection of seismic wave acceleration
Inventor: HALL JUN ERNEST M
IPC: B06B1/06
Filed: 1977-04-21
Abstract: Seismic investigation of sections of the earth's crust beneath the surface and esp. in the neighbourhood of stretches of water, are carried out by means of instruments incorporating devices some of which are sensitive to the pressures of seismic waves whilst others are sensitive to the acceleration of these waves in signals reflected from below. The composite seismic sensor has a pressure transmitting mantle with two output terminals, a detector reacting to acceleration in the seismic waves and a seismic pressure sensitive unit; the output terminals being connected to the detectors. A mercury switch is linked to the acceleration meter so as to short circuit it, if the meter is tilted too far from the vertical. Acceleration sensitive instruments can be used in boggy, and semisubmerged zones such as bays and river areas together with pressure sensitive instruments, the signals from which are either in phase or 180 degrees out of phase, and in either case can be combined in any way desired. It is now possible for the first time to carry out seismic investigations in water and then to use acceleration sensitive instruments, possibly in the bottom of a river and correlate the results. It is possible also to produce a composite instrument with a pair of pressure sensitive and acceleration sensitive detectors and combine the results.

Title: Yarn loop transporter for conditioning plant - has spars progressing loops towards channel outlet vibrating vertically and horizontally
Inventor: TURCK ERNST DIPL ING
IPC: F26B13/00
Filed: 1977-06-08
Abstract: Loops of yarn arranged very close to each other are transported through the processing channel of a yarn conditioning installation, at the inlet end of which a coiling device generating the loops of yarn is positioned. Two spars extend from in front of the inlet, to a point beyond the outlet. These progress the loops in steps through the processing channel and are caused to oscillate by a vibrator imparting motion with a vertical and a horizontal component. System eliminates the replacement of belts which deteriorate rapidly with their support rollers under the conditions of intermittent heat and cold. The tension on the yarn loops is constant and since the loops are never stationary, the treatment of the yarn is uniform.

Title: Interference signal detection in model radio remote control system - involves blocking transmitter between series of commands, and connecting receiver tuned to transmit frequency to transmitter antenna
Inventor: BECKER MANFRED
IPC: G08C25/00
Filed: 1977-06-21
Abstract: The frequency of the interference signal is identical with the transmission frequency used for controlling the model. The control system transmits to the model receiver in cyclical sequence frequency or amplitude modulated carrier control commands split in individual channels. The system transmitter carrier frequency signal is blocked for a specified period (Tu) after transmission of a control command corresponding to the last channel and before scanning the first channel command. An additional receiver near the operator, tuned to the system's transmit frequency, is switched on and connected to the transmit antenna. When interference signals are preset, an alarm is tripped.

Title: Machine for attaching connectors to electrical cable - has tool movement-driven feed via lever connected to tool via elastic element
Inventor: RESCH ALOIS RUPPERT
IPC: H01R43/048
Filed: 1977-10-20
Abstract: The mechanism is used with automatic machines for fitting the contact points to the wires. The machine uses a strip from which the contact points are formed. When the strip has sufficiently advanced so that the front end is caught by the feed lever, it is carried along during the feed stroke towards the press jaws. During the reversing motion of the feed lever it releases the contact strip. While the lever moves in the opposite direction, the contact strip is clamped by a brake mechanism. In the rear dead centre position of the swinging motion of the arm the front end of the feed lever grips the contact strip again and moves it by the distance of a contact length.

Title: Fabric cleaning process - has drum speed control to progressively increase centrifugal forces acting on fabric
Inventor: KRUESSMANN HELMUT DIPL CHEM DR
IPC: D06F35/00
Filed: 1978-08-28
Abstract: In the cleaning process for textile materials, partic. less flexible fabrics, the drum rotation in the initial cleaning stage is controlled to exert a centrifugal force at the drum lining of 0.3-0.5G. The centrifugal force at later cleaning stage is 0.7-1.2G. Between the initial and the final cleaning stages, the cleaning is applied using higher centrifugal forces than the first stage, but at lower levels than the final stage, so that e.g. the first stage exerts 0.4G and the second and final stage is 1.0G. The process ensures that there is an effective and positive cleaning action on the fabric, without leading to a greying effect on the material.
