Patent DE-3312407-A1 (DE)
Title: Device for disentangling rods
Inventor: PEDDINGHAUS ROLF DIPL ING
IPC: B65G47/14
Filed: 1983-04-06
Abstract: The invention provides an improvement of the proposal of Patent Application P 2916228.5. To this end the raisable and lowerable supports proposed there, which serve for the separating out of rods at first deposited in a bundled state, is modified in that downwardly directed, vertical recesses extend respectively from the centre piece, which recesses have a vertical guide for raisable and lowerable partitions. At their upper position the partitions form substantially the centre piece of the supports, by contrast with which in their lower position they lie below a conveying plane formed by the conveyor rollers mounted in the supports. After the initial raising of the supports, the rods remain lying partly on their centre pieces. By lowering the partitions the rods which remain lying fall onto the conveyor rollers and thus undergo a further separation. This prevents rods being able to slip off sideways during the conveying, so that a channel is formed for the conveying which is delimited by the side walls of the vertical guide.

Title: Vertical-hook composite mat
IPC: E21D11/15
Filed: 1983-09-27
Abstract: A composite mat comprising longitudinal and cross bars crossing one another is provided for the permanent lining of roadways in underground mining and tunnelling. The longitudinal bars of the composite mat have a vertical hook at one end and a load-displacement part, causing work of deformation when compressive and tensile forces occur, at the other opposite end. This load-displacement part to be deformed is designed as a wire which forms a hairpin-shaped horizontal loop and is additionally bent out of the loop plane. The slip ring is positioned in the curve thus formed and, after the vertical hook of the adjacent lagging mats is put in, forces recovery of the hairpin-shaped wire. The loop can be designed as a flat part enclosing the two wires of the corresponding loop or as a continuous bar, both being arranged to be displaceable, and thus enabling a joint to be formed which increases the deformation resistance and holds for a long time at a uniform height. <IMAGE>

Title: Device for detecting shorted turns
Inventor: WANTKE JOHANN DIPL ING
IPC: G01R31/34
Filed: 1984-02-14
Abstract: The invention relates to a device for detecting shorted turns in rotors of collector machines. In spite of careful fabrication, there is always a risk that shorted turns occur in the rotor. It is therefore the object of the invention to create a protection for the motor mentioned initially, which detects the shorted turns in the rotor during operation and switches off the motor as quickly as possible. The device according to the invention for detecting shorted turns in rotors of collector machines is characterised by the fact that a sensing probe arranged close to the collector is provided in the machine housing, which probe detects the variable magnetic fields of the rotor, occurring in the individual windings due to the short- circuit current in the event of shorted turns, during its rotation. This invention makes it possible for the first time immediately to detect shorted turns in the rotor so that no greater damage occurs in the rotor. Shorted turns generate a short-circuit within the rotor winding so that, in addition to the normal current, the short-circuit current also flows through one or several turns.

Title: Method for measuring velocity components
Inventor: BAHNEN RUDOLF DIPL ING
IPC: G01P5/26
Filed: 1984-06-08
Abstract: In a method for measuring velocity components of a particle situated in a flowing medium, it is assumed that the measuring time of the evaluation systems is generally substantially shorter than the dwell time of a particle in the measurement volume. It is therefore possible to disconnect a first measurement volume after measurement and to connect a measurement volume which is perpendicular to the first measurement volume. In conjunction with only one evaluation system and a simple optical design, this multicomponent measurement makes it possible for the entire laser power to be introduced sequentially into each desired measurement component and for the desired measurement components to be measured.
