Patent DE-3105316-A1 (DE)
Title: Cable bushing with strain relief
Inventor: SIMON HANS
IPC: H02G3/06
Filed: 1981-02-13
Abstract: The invention relates to a cable bushing having strain relief. Such a cable bushing consists essentially of a bushing sleeve which is firmly inserted into a housing aperture, and to a clamping element which is inserted into the sleeve and surrounds the cable. The cable bushing allows electrical connecting cables to be passed through the housing wall into the interior of electrical apparatuses or machines. In the event of external tension on the cable, the tensile force is transmitted via the sleeve to the housing and the electrical conductors, and thus the connecting terminals inside the housing, are therefore freed of the tensile force and thus, for example, cannot accidentally be pulled off. The actual clamping or tightening device of the clamping element is a clamping strip which rests on the cable over a part of the cable circumference. One end of the clamping strip is fixed with respect to the sleeve. The other end of the clamping strip is on a head part of the clamping element, which can rotate with respect to the sleeve and can be latched in the respective rotation position. Rotating the head part with respect to the sleeve in the one direction produces clamping and in the other direction releases the cable.

IPC: B41C1/05
Filed: 1981-09-25
Abstract: The invention relates to a method of producing a print for plastic veneers, plastic films, floor coverings and the like, which are provided with a print by the gravure method using an electronically engraved printing cylinder (production cylinder). In order that prints can be produced more cost-effectively and, above all, in a manner which is closer to the original, a metal foil is to be applied to a cylinder and electronically engraved on its outside so that it is identical to the production cylinder and subsequently chromium-plated, the metal film then being detached from the cylinder and attached to a printing plate and used in this form for the print.
Patent DE-3141295-A1 (DE)
Title: Gas spring with an extension force controlled as a function of temperature
Inventor: MOELDERS WERNER ING GRAD
IPC: F16F9/52
Filed: 1981-10-17
Abstract: The invention relates to a gas spring having the object of achieving an extension force of the piston rod which is controlled as a function of the temperature. This object is achieved in that the volume of the operating chamber into which the piston rod descends can be varied as a function of the temperature by means of a separating wall, and the desired extension force behaviour of the piston rod is thus achieved in a temperature range.

Title: Filling valve for a valve bag
Inventor: BUESCHERHOFF BERND
IPC: B65D30/24
Filed: 1982-01-30
Abstract: The invention relates to a filling valve for a valve bag, which consists of a piece of foil shaped to form a flat tube and inserted between an end folding flap and the side folding flaps, folded onto it, of the bag bottom, before the side folding flaps are folded shut. According to the invention, the flat tube has a foil tab projecting beyond an inserted tube end into the bag. This affords the advantage that the foil tab is pressed by the filling material against the bottom of the filled valve bag on the parting side of the bag and is laid against the bottom, so that an end of the flat tube opening into the bag interior is sealed.

Patent DE-3211247-A1 (DE)
Title: Process for reducing the oxygen content of the atmosphere of a continuous annealing furnace, and annealing furnace to perform this process
Inventor: PETZI FRITZ ING GRAD
IPC: F27D19/00
Filed: 1982-03-26
Abstract: In continuous annealing furnaces for ceramic materials, particularly for low-retentivity ferrite, the oxygen content of the furnace atmosphere is to be set exactly to very low, predetermined values. With some materials to be annealed this gives rise to difficulties, since the materials themselves release oxygen to the furnace atmosphere. To overcome the difficulty, the O2 content of the furnace atmosphere is to be measured at the place in the furnace to be affected, and in dependence on the measurement result a preferably hydrogen-containing fuel gas is introduced into the furnace in quantities such that the desired oxygen content is established. The fuel gas may be, among others, illuminating gas, natural gas or methane. A furnace design suitable for practice of the process is furthermore described. The furnace is divided into chambers, each of which contains, in the regions where the oxygen content is to be reduced, an oxygen measurement probe and at least one nozzle for introduction of the reducing gas.

Title: Heat meter
Inventor: FROELICH WALTER
IPC: G01K17/16
Filed: 1982-12-17
Abstract: A heat meter having a resistance measuring bridge whose platinum measuring resistors detect the feed temperature, on the one hand, and the return temperature, on the other hand, having a constant-current source which is voltage-controlled by a reference voltage, having a flow meter in the return branch, having a voltage-frequency converter for the diagonal voltage of the resistance measuring bridge, which generates a pulse sequence having a repetition rate proportional to the voltage, and having a counter for the pulses of the pulse sequence. The technical problem consists in the compensation or balancing of the thermal coefficient by measures of control engineering. The diagonal voltage is fed back as a positive feedback voltage (Up) via an amplifier (10) of constant gain (p). An addition stage (2) sums the reference voltage (Uref) and the positive feedback voltage (Up) and passes on the sum voltage (Uref + Up) at the input of the constant-current source (3). <IMAGE>

Title: Circuit arrangement for monitoring an electrical voltage
Inventor: HOFMANN GEORG ING GRAD
IPC: G01R19/165
Filed: 1982-12-18
Abstract: In this circuit, operating and release values can be linearly adjusted. At a voltage divider, a reference voltage can be set which is used as reference quantity for a voltage comparator. If the voltage to be monitored exceeds the reference value, a switch is operated which connects an adjustable auxiliary voltage to the voltage divider. The reference voltage is changed by a factor of < 1 and now represents a release value below which the voltage must drop. It is only then that the switch opens again.

Filed: 1983-03-10
Abstract: The circuit essentially comprises a number of memory cells which are constructed, for example, from simple D-type flip-flops without latches and the data inputs of which are connected to a common input and the clock inputs of which are connected via a decoder to a binary counter. By incrementing the binary counter, the logical state at the input is written successively into successive memory cells and in this way the shift register function is realised. The circuit according to the invention has a considerably lower energy consumption than a shift register of a conventional type. <IMAGE>
