Patent DE-2712872-A1 (DE)
Title: Superconductor overcurrent limiter in AC circuit - consists of hollow outer conductor with super conducting layers
Inventor: GERLACH HORST DIPL ING
IPC: H01B12/06
Filed: 1977-03-24
Abstract: A superconducting cable is used for conveying alternating currents. It has very low losses and is inserted in a mains supply network where it acts as an over-current limiter without any additional circuits. The superconductor (1) is connected to the outside or inside of a hollow conductor in the form of a layer (2). The layer can be built up of wires or strips (20). The outer conductor of the cable also consists of a hollow conductor (3) with a super conducting layer (4) on the inside. The hollow conductors are coil shape with the number of turns being a function of the super conducting layers. The inductive resistance of the conductor is less than the resistance of the super conducting layer in normal conditions. On the over-current condition, the inductive resistance will increase to limit the value to the rated current.

Title: Frequency divider with binary counter - has AND circuits whose inputs can be connected to counter outputs by=passing resistors in connecting wires
Inventor: WECHSELBERGER ERICH
IPC: H03K23/66
Filed: 1977-09-02
Abstract: A standard frequency is applied to the counter timing input, an ANd circuit inputs are connected to the counter outputs, and its output to the counter resetting input. Pulses applied to this resetting input are the frequency divider output pulses. A resistor (3-6) is inserted into each wire connecting the counter (2) outputs (01-04) with the AND circuit (7) inputs (E1-E4). Counter (2) outputs (Q1-Q12) and the AND circuit (7) inputs (E1-E4) can be connected with each other by a switching device (9) of the crossbar type. When a direct connection between AND circuit (7) input (E1-E4) and the counter (2) output (Q1-Q12) through the switching device (9) is made, resistors (3-6) are ineffective.

Title: Printing head nozzle covering system - has catch to unlock adjustment mechanism on head movement into side position
Inventor: JOHANNSEN FRED ING GRAD
IPC: B41J2/165
Filed: 1977-10-15
Abstract: The system has an adjusting mechanism between a printing head and a cover strip, and a feed mechanism to slide the strip for the width of a covering zone.

Title: Handling water-cooled reactor fuel elements in two-tier pool - with safety trolley below upper rack units during handling
Inventor: GHEZZO MIHAIL DIPL ING
IPC: G21C19/07
Filed: 1978-09-18
Abstract: A store, esp. a storage pool, for rod-shaped fuel elements esp. from light water reactors, contains two layers of storage racks for the elements. A travelling trolley in the store has a plan area at least equal to that of a rack unit used in the upper layer of storage racks. This travelling trolley accompanies the movement of a rack in the upper unit when the rack is being positioned. The trolley may itself constitute the handling device for a rack unit of the upper layer or may merely follow beneath it while the rack unit is handled by an over head crane. The possibility of a rack unit contg. fuel elements falling through the dpeth of the lower layer to the bottom of the pool if the crane should fail is eliminated.

Title: Plisse fabric produced from close-set woven fabric - by addition of longitudinal pretensioned elastic threads
Inventor: ADRIAN HANS-GERHARD
IPC: D05B35/08
Filed: 1978-11-18
Abstract: A plisse fabric, suitable for covers and curtains, is produced from a close-sett woven fabric of wool, cotton or synthetic yarns by the addn. of a series of pre-tensioned elastic threads running along the length of the fabric at regularly-spaced intervals across the width. Each of the elastic threads is attached to one side only of the fabric by means of a lock stitch seam, and crosses from one side of the sewing needle to the other between successive stitches, to assume the form of a shallow meander parallel to the plane of the fabric. The elastic thread is drawn from a large-capacity package instead of from a small hand-wound knitting-machine spool, permitting long, uninterrupted runs of high efficiency, giving material of uniform high quality.

Title: Quadrilateral guide rod hinge for swivelling connection - has rod hinge points closer together at base end, for wider swivel
Inventor: FELKEL GEORG
IPC: E05D3/06
Filed: 1979-01-18

Title: Vane type rotary hydraulic motor - has vane ends curved to produce radial movement by hydraulic pressure and reduce friction
Inventor: FUERST JOSEF DR
IPC: A46B13/06
Filed: 1979-03-31
Abstract: The motor casing (1) has a volute cross section cylinder, within which a rotor (2) touches the volute at its narrowest point and carries vanes (6, 7) which slide radially in slots in the rotor. The end of each vane, nearest the narrowest part of the volute, lies inside the rotor and the opposite end touches the cylinder. Water entering through an inlet port (14) presses on the vanes and thus turns the rotor, and leaves through a discharge port (5). The ends (9) of the vanes are turned to face upstream. As they pass the outlet port the water pressure on the downstream side pushes them into the rotor.

Title: Polybutylene glycol di:ester prepn. - by polymerising THF in presence of carboxylic acid anhydride and fixed catalyst bed of fuller's earth
Inventor: MUELLER HERBERT
IPC: C07C67/24
Filed: 1979-04-25
Abstract: In the parent patent polybutylene glycol dicarboxylic acid ester of formula RCOO-(CH2CH2CH2CH3)-n COR1 (I) (where R and R1 are alkyl, carboxy contg. opt. ethylenicall unsatd. aliphatic gp. or a carboxy contg. aromatic gp. and n is 2-200) is prepd. by polymerising THF in the presence of carboxylic acid anhydrides (II) and Fuller's earth (III) with a water content 3wt. as a catalyst.

(III) pressed and dried at >100 degrees C is not destroyed by the THF or (II) but maintains its shape for a very long time e.g. >=1 year, maintains its original shape and shows no abrasion. Since removal of the powdered catalyst in the absence of air is no longer required, the process is simplified and the quality of the prod. esp. colour and polymerisation degree, are improved and can be reproduced. (III) remains active continuously so long as highly pure THF is used.

Title: Dual control foot pedal operation indicator - has stationary spring contact and moving pin on pedal axle to close electrical circuit when dual pedal is depressed
Inventor: MAURER HARTMUTH
IPC: B60Q5/00
Filed: 1979-05-05
Abstract: The main objective of the proposed contact arrangement is to provide a robust electrical switch which is reliable, easily inspected, and easily repaired. The axles (3, 4) of a dual control pedal arrangement pass through a bearing block (2) bolted to the vehicle floor. Attached to the top of the bearing block is a strip of spring material (11) with tongues (15) free to move. On each axle is a radial pin (10) electrically isolated from the spring. When a pedal is operated it moves from the rest position (A) to the depressed position (B), and the axle rotation brings the pin into contact with the spring to close the electrical circuit and operate an audible and visual indicator. The construction is simple requiring no pressure operated switches or specially shaped cams. The contact mechanism can be easily checked visually for faults or damage.
