Title: Terminal strip for telecommunications cable cores
Inventor: QUANTE HERMANN
IPC: H01R4/24
Filed: 1982-04-30
Abstract: The terminal strip has a live screw terminal which is arranged in an insulating material housing, on one hand has an insert for a current conductor which can be used as a telecommunications cable core and is surrounded with an insulating sleeve, and on the other hand has an insert for a telecommunications core which can be used as an overhead line and has a current conductor which is enveloped in insulating material. The telecommunications cores can be connected to one another in the screw terminal while they are live. In order automatically to penetrate the insulation when the screw terminal is tightened, the latter is formed from a contact link which is fixed at the foot of the insulating material housing and from a compression bracket which engages over said link and can be displaced with respect to the contact link by a compression screw which is fixed in the insulating material housing in the axial direction but can rotate. Both the contact link and the compression bracket have insertion openings in their mutually tangential limbs, with slots that continue in the displacement direction, said slots running in the opposite direction in two mutually tangential limbs.

Title: Loading arm for liquid or gaseous products
Inventor: RICHE ROBERT MARCEL
IPC: B67D7/00
Filed: 1982-05-12
Abstract: The invention relates to a loading arm for liquid or gaseous products, having a jib which is supported by a vertical column and which is connected to a downpipe, and having a counterweight, the arm of which is held parallel to the downpipe by means of a parallel guide rotatably about a horizontal axle, a pendulum being freely suspended on the axle, whilst arranged on both sides of the pendulum are respective signal transmitters which can be actuated by the pendulum for the purpose of controlling the return movement of the loading arm in the event of emergency separation. To allow a controlled return in the event of emergency separation, there is arranged on the axle in a floating manner a ring connected frictionally to a driver which follows the position of the downpipe. At the same time, the ring has a stop on each of the two sides of the pendulum and the weight of the pendulum is so great that the ring is retained as a result of the engagement between the pendulum and one of the stops.
Patent DE-3218473-A1 (DE)
Title: Method of soldering honeycomb-like cellular structures to a cover plate and a base plate
Inventor: ITTNER NELSON CARL
IPC: B23K1/00
Filed: 1982-05-15
Abstract: The soldering material, in particular hard-soldering material, is arranged in the form of individual strip sections between successive honeycomb-like cell apexes or cell nodes in such a way that various strip sections of this type are arranged in parallel planes to one another, perpendicularly to the planes of the cover plate and base plate, when the cover plate and base plate accommodate the honeycomb-like cellular structure between them in a sandwich-like manner. The strip-shaped solder material can then be melted by transfer of heat so that it flows into the node points of the cellular structure and also into the connection locations at the contact lines between the cell walls and the cover plate and base plate. Excess solder material on the surfaces, facing one another, of the plates connecting the cell openings is thereby virtually avoided, and the desired ductility and stretching capacity of the entire structure are obtained.

The combination yarn exhibits very high elasticity and good processability to give knitted and woven goods.
Patent DE-3220781-A1 (DE)
Title: Contact element for solder-free attachment in printed-circuit board holes
Inventor: HARTING DIETMAR
IPC: H01R12/58
Filed: 1982-06-02
Abstract: For a contact element for solder-free attachment in preferably metallised printed-circuit board holes it is provided for the pressing-in section (1) to be constructed by stamping with two side parts (4) which can move on one another, the side parts being arranged at an angle  alpha  with respect to one another. In this case, the side parts are connected to one another at their root by means of a connecting point acting in a resiliently elastic manner or by means of a thin, resiliently elastic web (13). For matching to holes having the minimum diameter, it can furthermore be provided that the side parts are designed to be suitably thin so that they are themselves flexible in a resiliently elastic manner. The edges (10', 10'') of the pressing-in section which come into contact with the hole wall and in this case make contact with the metallisation of the wall by means of triple or quadruple edge pressure, are furthermore provided with radii in order to prevent damage to the hole metallisation when they are pressed in. Contact elements of such construction can thus easily be removed from a hole and a new contact element can be pressed into the same hole. <IMAGE>
Patent DE-3223697-A1 (DE)
Title: Method of operating pressureless solar absorber mats
Inventor: HOELTER HEINZ DIPL ING
IPC: F24S90/00
Filed: 1982-06-25
Abstract: It is known to operate absorber mats such that they are acted on either by pressure or by reduced pressure. In the first case, the disadvantage arises that permanent deformations can occur in mats made of plastic and subject to a large heat build-up, and welded connections can loosen. In the second case, there is the danger of a deformation occurring in the plastic channels of the heat absorption mats in the event of a strong build-up of heat and the necessary further supply of heat absorption liquid. To prevent these disadvantages, it is proposed according to the invention that the absorber mat (3) on the roof (1) of the house be connected to a pressure reservoir (2) which delivers precisely the amount of liquid pressure upwards to allow the liquid to be transferred without pressure at the inlet of the mat (3), and that a pump system or suction duct system be installed on the suction side (4) such that only the resistance to throughflow of the liquid in the absorber mat (3) is spanned. <IMAGE>

According to the invention, a tensioner is substantially improved in that a tensioning element which is movable along a predetermined path of movement transversely relative to the longitudinal direction of the belt band and which thereby deflects the belt band in a loop-like manner is provided and is movable by means of spring force from a position of rest remote from the belt band into the deflecting position. <IMAGE>
Patent DE-3230511-A1 (DE)
Title: Compressor installation
Inventor: AMACKER STEPHAN DIPL ING
IPC: F04D29/58
Filed: 1982-08-17
Abstract: The compressor installation has a radial compressor (1) of the back-to-back type and is provided with an axial gas feed pipe (37). It furthermore has an intercooler and an aftercooler, both of which are arranged in an annular region surrounding the gas feed pipe (37) and are connected to outlet diffusors (12 and 14 respectively) of the two compressor stages. The aftercooler comprises a multiplicity of cylindrical elements (32') which are arranged parallel to the axis of the gas feed pipe (37) in an outer zone of the annular region and have a lateral spacing from one another such that the gas emerging from the intercooler flows through the gaps between the in each case adjacent elements (32') of the aftercooler to the second compressor stage. This reduces the gas-side pressure drop, leading to a saving of compressor driving power. <IMAGE>

Title: Method of position-correctly stopping a film
Inventor: DROEGE HARTMUT
IPC: G03B21/11
Filed: 1982-12-28
Abstract: For position-correctly stopping a film which is provided with film frames and can be moved forward or backward by a drive mechanism, on the film there are provided markings which are detected and evaluated by a detector device. The detector device is arranged at a predetermined distance ahead of the optical axis of the film trap. The selected film frame is moved in fast mode to the detector device by means of a drive mechanism influenced by a control circuit. Upon detection of a selected film frame marking in the detector device, the drive mechanism is switched over for reverse film running and the film with the selected marking, which continues to be moved on account of the inertia of the system, is moved back in fast mode in front of the detector device. After renewed detection of the film frame marking, the drive mechanism is switched over to slow mode. When slow mode is switched on, a film-length pulse generator is activated, the pulses of which are read in in a memory device in a manner similar to a shift register and are compared with a pulse comparison value for the distance between detector device and optical axis. During the slow mode, any further markings detected by the detector device are read in and their position is determined.

Title: Automatic turboreactive windmill with a variable setting angle of the wind vanes for the production of electric energy
Inventor: SAVIC SERGIJE
IPC: F03D15/00
Filed: 1982-12-28
Abstract: The automatic turboreactive windmill with a variable setting angle of the wind vanes operates in accordance with the recoil principle, and is used to generate electric energy with the aid of an AC generator (alternator). Use is made in this case of the movements of the air masses both in horizontal and in the vertical directions. This can be done because sufficiently strong vertical air flows are also present in air masses of different temperature and different height. This windmill produces a strong current in a permanently uniform wave for any wind strength. So that the speed of rotation remains constant, a special hydraulic unit is employed to vary the setting angle of the wind vanes automatically in accordance with the wind position, as a consequence of which a uniformly strong current is produced for any wind position.
