Granted: 1985-04-04
Abstract: The invention relates to a locking device for the purpose of preventing unintentional tipping of a transport container, in particular a slag pot, which is mounted by means of trunnions in a bogie and can be tipped about the trunnions by means of a drive, the device consisting of an element projecting from at least one trunnion, perpendicularly to the axis of rotation in a manner dependent on the rotation of the trunnion and of a retention element, which is attached in a movable manner to a bogie and, under the action of a force-exerting element, arrests the projecting element in a predetermined position. In order by simple means to create a low-wear arresting means which holds the transport container reliably in a predetermined position, it is proposed that a roller 41 be arranged on the head of the projecting element 4, with its axis parallel to the axis of rotation of the trunnion 5, that a run-up curve 31 be provided in the retention element (lever 3) on the side facing the trunnion 5 and that a force-exerting element 2, which acts on the retention element 3 and, in a swivelling range of the projecting element 4 along the majority of the profile of the run-up curve 31, presses the retention element (lever 3) against the roller 41, be secured on the bogie 1. <IMAGE>

Title: Method and device for bridge welding
Inventor: SCHULTE KARL
IPC: B23K11/00
Filed: 1987-12-07
Granted: 1989-02-16
Abstract: Until now, wire grids to be welded together have been brought, in one plane, between upper and lower electrodes of a bridge-welding device, in which the electrode bridges are arranged in the direction of the longitudinal wires. In this known device, a turning device turns individual grid sections and constitutes a limitation for the possible timing speed. The adjustment of the electrode spacings to different transverse wire spacings is awkward. The new method and the new device are intended to shorten the change-over times and the cycle times and make possible a greater work capacity. It is proposed to weld grids together, between the upper and lower electrodes, in two planes separated by central electrodes, the arrangement of longitudinal and transverse grids in the lower plane taking place in the opposite manner to in the upper plane. The turning arrangement and thus the limitation of the timing speed is no longer necessary. Likewise no longer necessary is the complicated displacement of the individual electrodes when the electrode bridges are aligned transversely to the longitudinal wires. <IMAGE>

Title: Hollow-beam electron gun for generating a hollow electron beam having low-scattering transverse velocity component
IPC: H01J3/02
Filed: 1988-08-12
Granted: 1989-11-30
Abstract: The invention relates to a hollow-beam electron gun for generating a hollow electron beam having a low-scattering transverse velocity component, in which the precondition is created by the electrode geometry and in particular by the position of the electron emission ring that leaving electrons initially strongly interact only with a present electrical field. The formation of space charges in front of the electron emission ring causes no deterioration of the beam property. The scattering of the transverse velocity of the electrons in the beam is low. The electron current can be switched by the electrode arrangement.

Title: Method for the production of buffered optical fibres
IPC: G02B6/44
Filed: 1988-09-26
Granted: 1990-01-18
Abstract: In previously known methods for the production of buffered optical fibres by using a filling material, electrostatic discharges occur which lead to operational disturbances of the extrusion devices and are due to an accumulation of static charges in the filling material.   When a filling material is used which contains conductive particles, that is to say when these are electrically conductive, disturbing discharges no longer occur during the production of optical fibre cables or buffered optical fibres. Production of buffered fibres with optical fibres.

Title: Cold pilger rolling mill for the cold-rolling of tubes (pipes)
Inventor: STINNERTZ HORST ING GRAD
IPC: B21B21/00
Filed: 1993-10-11
Granted: 1995-05-04
Abstract: The invention relates to a cold pilger rolling mill for the cold-rolling of tubes from metallic materials, which lend themselves well to deformation, by means of a pair of grooved rolls, which can move back and forth and roll up on the intermittently stationary and rotated tube blank, and a rolling mandrel which is held in the interior of the tube blank, rolls and rolling mandrel having reducing-pass and smoothing-pass zones.

Patent DE-4344867-C1 (DE)
Title: Digital phase detector
Inventor: MELLER WOLFGANG DIPL ING
IPC: G01R25/04
Filed: 1993-12-29
Granted: 1995-04-06
Abstract: The invention relates to a digital phase detector for determining phase shifts between a comparison clock (VT) and a reference clock (RT). First means (STA, STO) produce start and stop signals from the pulses of the reference and comparison clocks (RT, VT). A counter (ZG, Z) counts in the time window between a start signal and the subsequent stop signal the pulses of a higher-frequency counter clock (ZT). The counter value of the counter (ZG, Z) constitutes a measure of the phase shift. Digital phase detectors of this type have quantisation errors. By using sign information (VZ) which is obtained from the comparison clock preceding or following the reference clock, and means (MP) which add a constant to the counter value, the effects of the quantisation error can be considerably reduced. The phase detector according to the invention allows phase-control loops with accurate clock compensation, since it provides a control signal even in the case of the smallest of phase shifts between comparison and reference clock. <IMAGE>

Patent DE-4403045-C1 (DE)
Inventor: PLESCHIUTSCHNIGG FRITZ-PETER D
IPC: B22D11/04
Filed: 1994-01-28
Granted: 1995-09-07
Abstract: The invention relates to a continuous casting facility for the production of continuously cast metal in the form of slabs, thin slabs, cogs and billets. The facility ensures that the casting runs centrally along the entire course of the guide, thereby ensuring a high level of casting reliability at casting rates of up to 6 m/min. The cambered, concave shape of the ingot mould and of the entire guide means that the casting is guided along the axis of the guide from the meniscus to its exit at the end of the continuous casting facility, thus eliminating sideways motion ("snaking") of the entire casting in the direction of one of its small sides.

Filed: 1994-10-19
Granted: 1995-12-14
Abstract: The control parameter is determined by first using a first thermometer (7) to determine the temperature of the drying air.
