Patent DE-3305363-A1 (DE)
Title: Screw-in terminal for lightning protection
Inventor: PROEPSTER JOHANN
IPC: H01R4/44
Filed: 1983-02-17
Abstract: There is a screw-in terminal in which two compression pieces (1,2) are in each case provided with a contact groove (8), and two conductor wires (5,6) are arranged in in each case one of the contact grooves. In this case, it is desirable for the contact surface to be enlarged between two mutually crossing conductor wires and for a uniform contact pressure to be ensured at all times. This is achieved by a contact plate (3) being arranged between the two compression pieces (1, 2), and the pressure of the contact plate (3) against the conductor wire (5, 6) always being uniform over the length. A uniform contact, between the conductor wire and the contact plate, along the conductor wire in the region of the terminal is always ensured by tightening the only one screw, so that an enlarged contact surface with the conductor wire is created in every assembled terminal. <IMAGE>

Title: Method for detecting an earth or short-circuit current
Inventor: GESING REINHARD
IPC: G01R19/30
Filed: 1983-12-07
Abstract: To detect the actual value of an earth or short-circuit current in earthed alternating-current systems, a measuring method is proposed in which the value of the current is measured and stored in successive periods. The stored value is replaced by the next-higher measured value when the measured values exceed the stored value in two successive measuring periods. The measurement is not taken synchronously with the zero crossings of the current. The second measuring period can be delayed by the length of at least one period.

Patent DE-3346481-A1 (DE)
Title: Hydrostatic travel drive
Inventor: BRUGGER KLAUS DIPL ING
IPC: F16H61/46
Filed: 1983-12-22
Abstract: The invention relates to a hydrostatic travel drive for a vehicle, preferably an off-the-road vehicle, with at least one driven axle and with at least two hydraulic motors which are assigned to the driven axles or the wheels on each axle, with at least one main pump for acting on the hydraulic motors in drive operation and with a hydraulic differential compensation and a differential lock. In known travel drives of this type the differential lock must be switched on and off. According to the invention the hydraulic motors are connected in series following one another in a main circuit and a control valve is arranged in a secondary circuit connected to the main circuit, which valve has two flow passages for an adjustment hydraulic quantity, of which one is at any time automatically openable for bypassing the hydraulic motor having the larger pressure differential in the event of a difference between the pressure differentials in the two hydraulic motors, until such time as the differentials are adjusted. The differential lock no longer needs to be engaged and disengaged. There is equal transmission of the tractive force even in the event of one wheel slipping. The differential is balanced in all drive conditions. With the same starting tractive force, twice the speed of travel is possible.

Title: Hollow-cylindrical rotor for a regenerative heat exchanger, and method for producing it
Inventor: SPENGLER FRANZ
IPC: F28D19/04
Filed: 1984-01-21
Abstract: The circumferential surface (4) of the rotor (1) consists of one or more layers (12, 13) of a strip (11) which is oriented on edge in the radial direction and helically wound. The strip (11) is profiled with a step-shaped undulating structure and is gathered up at its radial inside edge (22). The angle ( alpha ) between the rear (20) of the profile and the sides (21) is at most somewhat more than 90 DEG , e.g. at most 100 DEG , and decreases from the radial outside edge (24) towards the radial inside edge (22) of the strip (11). In particular, the strip (11) can be profiled in the shape of a rectangular step at its radial outside edge (24) and in the shape of a trapezium at its radial inside edge (22). An embossed rectangular step profile is used as a starting point for producing this strip contour. Pinned-shaped forming dies (27-29) are moved into the profile waves, and the strip (11) is thereby gathered up at the radial inside edge (22). Post-forming of the strip can be performed by bending or pressing. <IMAGE>

Patent DE-3407165-A1 (DE)
Title: Loading bridge for ramps
Inventor: ALTEN KURT
IPC: B65G69/28
Filed: 1984-02-28
Abstract: The invention is based on bridges of this type in which a folding extension for placing on the vehicle or the like is provided at the front of the bridge superstructure, the said extension having narrow sections on both sides for adaptation to platforms of different widths. In order to prevent these lateral sections from catching in the ramp recess when the bridge superstructure has to be inserted into the ramp recess, stops are allocated to the sections, the former intercepting the latter in the case of a downward folding movement, before a supporting position has been reached. Accordingly, only the other sections of the extension (central section) can adopt a supporting position to support the bridge superstructure in the rest position, when the bridge is not in operation.

Patent DE-3426022-A1 (DE)
Title: Mechanical drawing instrument for perspective drawing
Inventor: GNISA FRANK
IPC: B43L13/14
Filed: 1984-07-14
Abstract: This perspective drawing machine displays directly, on mechanical scanning of an existing point in the plan view, the corresponding point in the perspective with the height adjusted. This procedure can also be reversed. The apparatus consists of mechanical parts, such as spindles, joints, sliding blocks and rules. These parts interact in accordance with the basic geometrical principle that radial lines of sight in the plan view become parallel lines in the perspective and parallel rays in the plan view become radial rays in the perspective. The point of intersection of a radial ray and a parallel ray in the plan view thus has a precise correspondence in the perspective. The possibility thus exists of precisely defining, in the perspective, points fixed by two rays in the plan view, and vice versa. To do this, it is merely necessary to represent mechanically the four abovementioned rays by means of rules and to produce connections between each pair of mutually corresponding plan view rays and perspective rays. This is done at common points in the plane of the image or the datum line, which are designed as articulated rule connections.
Patent DE-3438221-A1 (DE)
Title: Carbon electrodes, especially microelectrodes made of carbon fibres
Inventor: BESENHARD JUERGEN OTTO DR
IPC: H01M4/58
Filed: 1984-10-18
Abstract: Carbon electrodes and especially microelectrodes made of carbon fibres are described, which electrodes are pretreated by oxidative or reductive chemical or electrochemical intercalation, subsequent disintercalation largely reversing the intercalation reaction. After this pretreatment, the carbon materials are characterised by increased porosity and surface roughness; in addition, numerous lattice defects are introduced which, owing to their reactivity, rapidly react with substances from the environment, resulting in "functional groups" bound to carbon being formed. The porosity of, for example, carbon fibres pretreated according to the invention permits the construction of low-resistance microreference electrodes by the introduction of the corresponding components (for example Ag, AgCl, KCl solution) into these pores. The application of ion-selective layers makes it possible to refine such microreference electrodes to give ion-selective electrodes. The functional groups facilitate the application of diaphragms or ion-selective layers onto the electrode surface, as they can react with components of these layers or with "adhesion promoters". In addition, the functional groups are in part characterised by ion-exchanging properties. They permit the incorporation of metal ions which by subsequent reduction can then be reduced to give highly dispersed metals.

Title: Device for testing the radial play of resilient corrugated packing strips
Inventor: SATTELHAK JOSEF ING
IPC: G01B5/14
Filed: 1984-10-19
Abstract: It has been possible to date to measure the radial play of resilient corrugated packing strips only with the rotor dismantled. The device according to the invention can be introduced into the air gap, and the radial play of the resilient corrugated packing strips can be reliably tested or measured by means of the force/distance characteristic recorded by it. The two congruent wedge strips 4, 5 are introduced into the air gap of the machine. The winding 6 located in the stator 3 is mounted by means of the resilient corrugated packing strip 7 and the slot wedges 8. The two wedge strips 4, 5 are moved by means of a mating strip 9 which is mounted on a tension bolt 10. The tension bolt 10 is supported in a hollow piston cylinder 11. The tension rod 10 is moved by means of a hydraulic or pneumatic device 12. A fine manometer 13 is interconnected into the line for the purpose of measuring the expenditure of force. The distance is measured by means of the distance dial gauge 14, which bears with its measurement pin 15 against the tension bolt. <IMAGE>

Title: Train ferry
Inventor: THIELE HEINRICH DR
IPC: B63B35/54
Filed: 1984-12-05
Abstract: In a ferry accessible via stern and/or bow gate (2) and intended for the transport of rail and/or road vehicles, containers or suchlike material to be loaded, in order to better utilise the space below the water line, reduce the vertical position of the centre of gravity and shorten the loading time, provision is made for the vehicles to rest on vertically adjustable tween decks (1) which are mounted on the side ribs (provided with profiled strips) of the ship and can be positioned at the level identical to the pier for the purpose of loading and unloading. The vertical adjustment is effected by means of hydraulically operable devices fastened to the cross beams of the decks. The propulsion is diesel-electric and is allocated to the fore-body and after-body (3, 4, 5). The type of construction is suitable for railway goods wagons and/or passenger carriages and also for road vehicles, it also being possible to provide fixed tween decks above the cargo spaces for accommodating passengers and drivers. The transport of rail and road vehicles can also be combined with container transport by using the main deck (9). <IMAGE>

Title: Glass sorting system
Inventor: KLUMPARENDT WOLFGANG
IPC: B07C5/342
Filed: 1984-12-13
Abstract: Glass sorting in glass sorting systems is not simply a matter of screening out small fragments and objects which are not made of glass: glass must also be sorted by colour into "clear", "brown" and "green". This work has hitherto always been carried out by hand, which is extremely uneconomical as well as being a job which people can hardly be expected to do. The invention proposes a system of this type which includes a coloured glass sorting device which automatically sorts the glass items according to colour by means of a light barrier which responds to colours. <IMAGE>
