Patent DE-3111255-A1 (DE)
Title: Power supply system
Inventor: MUELLER HANS CHRISTIAN DR
IPC: H01H71/40
Filed: 1981-03-21
Abstract: A power supply system, especially for the low-voltage range, has (apart from a power circuit breaker (3) which connects an input supply station (1) to the network) a load circuit breaker (6, 42) in each connecting line (7) which leads to a distributor station (8) and in each connecting line (43) which leads to a load. The first-mentioned load circuit breakers (6) are allocated in each case one tripping device having sensors for the temperature of the connected line and for a short-circuit current or earth-short current flowing through it, as well as a switching-off delay device which becomes effective when a short-circuit current or earth-short current occurs. These tripping devices are connected to a monitoring and control device (30). The monitoring and control device (30) has a short-circuit and earth-short point determining device (37) which, controlled by a microprocessor or microcomputer (31), uses metrology techniques to determine that line which has the short-circuit or earth-short, during the brief opening of the power circuit breaker (3) triggered by the short-circuit or earth-short, and, in the event of a short-circuit or earth-short in a connecting line (7), opens the load circuit breaker (6) allocated to this connecting line (7) by means of a command which is produced by the microprocessor or microcomputer (31). <IMAGE>

Title: Rotating cube
Inventor: OBERMAIER ANTON GEORG DIPL KFM
IPC: A63F9/08
Filed: 1981-03-23
Abstract: In this rotating cube (10), which represents a three-dimensional puzzle, small cubes (12 to 26) are guided on a core (28). The small cubes have recesses (34) at their bottoms, in the shape of a quarter of a sphere, and are provided with a pin (36) with a disc (38) moulded thereon. The pins (36) of all the small cubes are oriented towards the centre of the sphere (30) of the core (28). The core (28) consists of a sphere (30), to which discs (32) are attached, which form annular grooves for the guidance of the discs (38) of the small cubes. With the aid of the core (28) and of the small cubes of corresponding design, rotating cubes can be produced whose lateral surfaces consist of an even and of an uneven number of small cubes. To facilitate handling of the rotating cube (10), one small cube (22) is fixedly connected to the core (28). <IMAGE>
Patent DE-3113798-A1 (DE)
Title: Device and arrangement for the vacuum-free formation of contact between a transparent copying original and a light-sensitive layer in exposure units
Inventor: RUEDIGER JOHANNES
IPC: G03B27/18
Filed: 1981-04-06
Abstract: For the purpose of transmitting parts of characters in a copying original such as, e.g., letters and halftone dots in the graphical copying method or fine conductors in electronics, it is necessary to produce an intimate contact between the copying original and a light-sensitive support material such as a pressure plate or printed circuit board. For this purpose, use is made of pneumatic copying frames, the contact being produced by evacuation. In accordance with the invention, use is made as copying originals of thin metal foils which respond to a magnetic effect and into which the transparent character positions are etched or produced in an electrical way. These foils (2) are attracted by an electromagnet (4) and brought into intimate contact with the light-sensitive material (3). At the same time, a light source (1) is switched on and illuminates the material. When the required quantity of light has been reached, the lamp and the electromagnet are switched off. The original can, e.g., return to its initial position, and the support material can be transported further. With regard to an assembly line, this results in very short cycles which cannot be achieved in a conventional way. <IMAGE>

Patent DE-3130006-A1 (DE)
Title: Method of measuring a fluid volume flowing through a tube
Inventor: DOUBEAU ANDREAS DR
IPC: G01F1/716
Filed: 1981-07-30
Abstract: In a method of measuring a fluid volume flowing through a tube by means of the magnetic nuclear spin resonance, the magnetisable nuclei of the fluid volume are aligned by means of a magnetic d.c. field and synchronised by means of a magnetic alternating field. To achieve a measurement result which is independent of the respective aggregate state of the substance to be measured, a nuclear spin resonance is achieved with continuous timing of a 90 DEG  pulse whose interval is short relative to the nuclear spin relaxation, a voltage amplitude induced by the incoming protons being a measure for the volume flow.
Patent DE-3136840-A1 (DE)
Title: Fold-down exterior mirror
Inventor: HISCOX MARTIN
IPC: B60R1/076
Filed: 1981-09-16
Abstract: The invention relates to a fold-down exterior mirror for a vehicle, in particular a motor vehicle, with a mirror housing which is held on the vehicle on a base part such that it can pivot towards the vehicle about two spindles which are approximately parallel to one another, are vertical and are at a distance from one another, and with at least one preloaded, spring-elastic tensile member which is anchored by its one end in the base part and by its other end in the housing and extends through between the pivot spindles. The invention is characterised in that at least one of the pivot spindles is interrupted by a cutout which when the housing is folded down is open towards the tensile member, in that when the housing pivots into a folded-down parking position the tensile member can be displaced by the pivot spindle through into the cutout, and in that the housing is locked in the parking position by means of the tensile member displaced into the cutout. Without significant technical complexity, the parking position for the housing is defined here by the pre-loaded tensile member placed in the cutout.
Patent DE-3140568-A1 (DE)
Title: Device for hydraulic dredgers
Inventor: CORDES HUGO DIPL ING
IPC: E02F3/96
Filed: 1981-10-13
Abstract: Device for hydraulic dredgers for levelling, digging and ripping and for guiding loads or tools, such as drills, pile-driving or pulling tools on a rectilinear constrained path, by means of two arms of equal length which can be moved past one another out of one extended position, via the folded position, into the opposite extended position (Fig. 1). A long constrained path with a constant cutting position is achieved without movement of the boom. The position and direction of the path of motion can be chosen and can also be curved, with the result that the excavator shovel executes a favourable conveying path from the digging location to the emptying location and the exact shaping of embankments and ditches is possible. <IMAGE>

Title: Process and apparatus for the stacking of thermoplastic cups
Inventor: KIEFER GUENTHER
IPC: B29C31/00
Filed: 1982-02-02
Abstract: The invention relates to a process for the stacking of thermoplastic cups which are shaped, punched out and then stacked, and to an apparatus for carrying out the process. Stacking takes place in that the cups are transferred in an ordered manner onto an oblique chute, at the end of which rotates a pallet band having individual pallets with perforations. Because the cups are prevented by a sliding plate from penetrating completely into the perforations in the transfer region, these support the following cups until, during further transport, the next pallet stands under the following cup. The apparatus for carrying out the process is characterised by a rotating pallet band, an oblique chute and a sliding plate arranged in the transfer region. The invention is illustrated most pertinently by Figure 1. <IMAGE>
