Title: Device for plasma arc working of metals - e.g. welding, cutting or microwelding
Inventor: LEBEDEV VLADIMIR KONSTANTINOVI
IPC: B23K10/00
Filed: 1975-07-08
Abstract: Device for the plasma arc working of metals uses a symmetrical, three phase power transformer with adjustable short circuit resistance and legs at 120 degrees intervals. Each phase has one prim. and two sec. windings, one sec. feeding a rectifier providing direct polarity between electrode and workpiece, the other sec. feeding a rectifier providing inverse polarity between the workpiece and the plasma nozzle. A thyristor switch is fitted. The novelty is that the transformer has a shunt with premagnetising coils, and each sec. winding consists of two parts connected in series between the transformer and the rectifiers. Ten figs. are provided. The device is used for plasma welding, cutting or microwelding, for stepless control of the direct or inverse currents, e.g. in welding sheet 0.5-5 mm thick using direct polarity 16-100 amps and indirect polarity 8-50 amps.

Title: Printed character recognition system - permits recognition of partially overlapping characters
Inventor: TROPF HERMANN DIPL ING
IPC: G06V30/10
Filed: 1975-07-16
Abstract: The method for breaking down printed symbols in character recognition uses multiplicative comparison, which permits recognition to a certain extent of inadequately spaced or of partially overlapping characters, by elimination the need for a white zone recognition. In comparison with stored standards of comparison, a symbol which could be completely overlapped by a second having an additional limb, is distinguished by scanning the two dimensional area corresponding to the larger symbol to detect the presence of the second if a first result indicates the probability that the symbol scanned is the letter of the lesser extension.

Title: Plug in manifold connector for hydraulic fluid - has spring biased ball locked in recess in plug by fluid pressure
Inventor: KLOCKE HARALD
IPC: F16L39/02
Filed: 1975-08-27
Abstract: The manifold connector block (4) for pneumatic or hydraulic circuits has a row of pipe sockets (19) extended from the plug holes (3). A location slot (6) for the connector plug blade has a junction with another bore from which protrudes a spring-loaded steel ball (13). The steel ball can be pressurized from the fluid line through the cross drilling (18). After plugging in the fluid supply tube ends, the blade of the connector plug is locked in position by the pressurized steel ball (13) which fits in a recess. The manifold connector therefore remains locked for as long as the system is under pressure.

Title: LED with MIS structure using electron pairs recombination - generates intermittent minority carriers and separates them by gate electrodes
Inventor: SCHULZ MAX DIPL PHYS
IPC: H01L33/00
Filed: 1975-09-24
Abstract: The light is generated by the light emitting diode by recombination of tunnelling electron pairs in semiconducting monocrystals. The generation of minority carriers in a MIS structure is carried out intermittently. The minority carriers generating zone is spatially separated from the light generating recombination zone by gate electrods. The charge transfer is controlled by the potential applied at the respective gate electrode. Alternately the generation and the recombination zones are isolated by a separating electrode under suitable potential. This potential may be possibly used for the charge transfer control. Charges in oxide layer may be also used for the electri isolation of the two zones.

Title: Mine roadway support system - adjoining lagging sheets have bends and pleats intermeshing where overlapped
Inventor: BERNOLD JEAN
IPC: E21D11/15
Filed: 1976-04-30
Abstract: The mine roadway support system consists of steel arches and shaped lagging sheets arranged at right angles to the axis of the road. Lagging sheets are placed on the outside of the arch between adjoining shaped steel arches in such a way that bends (14, 15, 16, 17) punched out of the sheets in parallel lie parallel to axis of the roadway. Pleats (12, 13) arranged in rows parallel to the bends also lie parallel to the roadway axis. The adjoining sheets (8, 9) are partially overlapped so that their bends tooth together and thus couple the sheets to one another. It is also possible for both bends and pleats to engage or tooth together to form an even firmer supporting structure. The bends can be restricted to the areas where the sheets are to be overlapped for connecting purposes.

Title: Safety trap for combatting bank robbers - drops robber and jams trap cover for positive tighter clamping
Inventor: RICHTER KARL-HERMANN
IPC: E05G5/02
Filed: 1976-07-02
Abstract: The safety trap is used for a safety device against armed robbery in banks. The pit locking mechanism is dripped remotely by electrical systems. The rubber opens the pit cover by its body weight and falls into it and he is jammed automatically at about his chest level. The pit cover is hinged and situated under the carpeting on the floor. The robber's fall continues down to the trap bottom plate which is connected by pivoting shank to the top trap plate. The robber's efforts to free himself result in tighter clamping of the trap mechanism both at his body level and at his feet.

Title: Transfer device moving cast billets - from a multitrack continuous casting plant to an adjacent cooling bed
Inventor: SENFTLEBEN HANS-JOACHIM
IPC: B22D11/126
Filed: 1976-07-21
Abstract: A device used in conjunction with a multitrack continuous casting plant, transfers billets with different lengths onto the cooling bed. Lengths of the cast billets are fed onto a row of outlet roller tracks located at 90 degrees to glide rails which are raised to lift the bollets off the tracks. A pusher then transfers the billets to an adjacent cooling bed. The improvement comprises the hoist mechanism lifting the glide rails being actuated by the pusher. The pusher is pref. fitted with discs which engage with recesses provided in levers mounted on pivot shafts; and each lever is fitted with a roller which lifts the glide rails so the billets are transferred to the rails. The pusher also actuates the hoist, so a separate hydraulic-, pneumatic-, or electric-hoist, and the necessary control circuits are eliminated, giving a simple, reliable device with low maintenance.

Title: Automatic data storage system for measuring instruments - retains displayed figure until new measurement is taken without figure following signal interruption
Inventor: SCHUH WOLFGANG DIPL ING
IPC: G01R17/00
Filed: 1976-08-25
Abstract: The automatic storage system for electrical signals derived from measuring equipment is based on the sample and hold technique whereby the last measured value is automatically stored until a new measurement is taken. If the input signal falls below a given level or if the input signal varies at a speed in excess of a set rate then the measurement is interrupted. If there is no interruption, the measured value is displayed. If interruption occurs, then a flip-flop is triggered to inhibit the transfer of data to the display register so that the display shows the last figure prior to the interruption. For analogue measurements an additional intermediate store is required using sample and hold circuits.
