Patent DE-3131894-A1 (DE)
Inventor: THIELE GERD DIPL ING
IPC: H02M1/08
Filed: 1981-08-12
Abstract: A firing circuit for two antiparallel-connected power thyristors. Each of the power thyristors has a gate terminal; the gate terminals being connected by a series combination of auxiliary thyristors. Each of the auxiliary thyristors is of the type which can withstand firing resulting from excessive anode cathode potential; the sum total of the anode cathode potentials of the series-connected auxiliary thyristors being less than the anode-cathode breakdown voltages of the power thyristors. This, while a power thyristor is in a nonconductive state, an anode-cathode voltage is impressed thereacross in the forward conduction direction. At an anode-cathode voltage which is less than the breakdown voltage of the power thyristor, the auxiliary thyristors are fired so as to form a conductive path which includes the cathode-gate path of the other power thyristor, the auxiliary thyristors, and the gate-cathode path of the protected thyristor. Normal firing of the power thyristor is achieved via the auxiliary thyristors, which may be fired by light pulses or current pulses. Thus, the auxiliary thyristors perform protective and normal firing operations.

Patent DE-3137657-A1 (DE)
Title: Drive or conveyor belt
Inventor: LOOSE GERHARD
IPC: B65G15/36
Filed: 1981-09-22
Abstract: The invention concerns a drive or conveyor belt which is joinable together from individual part-lengths, for example by means of connecting hooks. The part-lengths have at least one woven fabric layer formed from weft threads composed of polyamide or the like and warp threads composed of polyester. The fabric layer may have a multi-ply woven construction. It preferably has been pretreated in such a way that in the rubberising step it is handleable essentially free of longitudinal tensions and thereafter vulcanisable without afterstretching. To enhance the strength and non-extensibility, the invention proposes in respect of a belt which is to be used underground that warp threads made of polyester are wholly or partly surrounded with polyvinyl acetate or polyvinyl alcohol or warp threads of polyester are assigned polyamide threads extending in the warp direction.

Title: Process and equipment for improving the ultimate yield in hydrocarbon deposits
IPC: E21B43/243
Filed: 1981-11-09
Abstract: To increase the ultimate yield of an underground hydrocarbon deposit (16), which has been penetrated by a probe (12, 18), gaseous fuel is mixed in a mixing device (32) with gaseous oxidising agent and injected by means of a compressor (26). An inert gaseous separating medium and finally a chemical igniting medium are then injected. The igniting medium reacts with the fuel/oxidising agent mixture and supplies the heat required for initiating a reaction between fuel and oxidising agent. This reaction in the hydrocarbon deposit especially provides heat energy, whereby ultimately the driving mechanism driving the oil to the probe is improved. <IMAGE>

Title: Beet-harvesting machine with topper
Inventor: BURS JOHANNES
IPC: A01D23/02
Filed: 1981-12-24
Abstract: Beet-harvesting machine with toppers are intended to make possible a clean topping and a virtually complete comminution of the beet tops and to work so that a clean field surface not obstructed by weeds remains, whilst, depending on the use of the machine, the comminuted beet tops can be distributed over the field and ploughed under or be collected for fodder purposes.

IPC: B22D17/22
Filed: 1982-01-15
Abstract: The invention relates to a clamping device for dies and moulds, having a hydraulically driven clamping jaw (4) having a self-locking wedge mechanism, in particular for the rapid fixing and release of the two mould halves (6) on a die casting machine, the clamping device being mounted on the T-slots (13) of the mould clamping plates (7) and, during actuation, the clamping jaw (4) moving into a clamping groove (15) of the mould half (6) and, by means of swivelling, clamping the mould half (6) against the corresponding clamping plate (7). For better transmission of force, it is proposed according to the invention that a rocker (3) be mounted to pivot about a pivot pin (8) in the free end region (4a) of the clamping jaw (4), which rocker interacts wedge-fashion with a slide (2) secured on the piston rod (9) of the hydraulic cylinder (1). By virtue of the rocker (3) there is always satisfactory contact with the two wedge faces (3a and 2a). For the clamping actuation, the piston rod-side piston face is furthermore pressurised. As a result, release is then effected with the larger force. <IMAGE>

Title: Method and device for feeding labels in bottle labelling machines
Inventor: ISRAEL REINER DR ING DR
IPC: B65C9/16
Filed: 1982-10-28
Abstract: The invention is used in labelling machines and relates to a method in which the labels are passed to a labelling cylinder from which they are removed by the bottles to be labelled and to a device with a rotatable labelling cylinder driven by a set of gears and with a rotating bottle table which transports the bottles to be labelled. The object of the invention is to reduce the spaces between the bottles on the rotating bottle table. The invention provides for rotation of the labelling cylinder with a periodically fluctuating angular velocity, with the labels being passed to the labelling cylinder at maximum angular velocity and being removed by the bottles at minimum angular velocity. In the device, the set of gears driving the labelling cylinder has a varying velocity ratio, so that the labelling cylinder rotates with a periodically fluctuating angular velocity or the labelling cylinder is connected to a motor which rotates at a periodically fluctuating angular velocity.

Title: Device for checking that a container has been completely filled with packages of cigarettes
Inventor: HEIBACH HEIKO
IPC: B07C5/10
Filed: 1982-10-30
Abstract: To permit checking that a container has been completely filled with packages of cigarettes, for example that a carton has been filled with bundles of 10 packets of cigarettes or that a bundle actually consists of 10 packets of cigarettes, the container passes through a measuring section between at least one radioactive emitter and a radioactive beam detector, for example a scintillation counter; it can be determined from the reduction in the signal measured by the detector which has occurred as the signal passed through the measuring section whether the container is completely full or whether at least one package of cigarettes, i.e. a bundle or a packet of cigarettes, is missing. The widths of the cartons concerned are simultaneously determined by means of light barriers, in such a way that a correlation between the change in the measured signal on the one hand and the width of the carton on the other hand can be made and fault-free recognition of defectively filled cartons is possible.

Title: Control device for thread machining on numerically controlled machine tools (thread turn offset compensation)
Inventor: BASILOWSKI HERBERT
IPC: G05B19/18
