Patent DE-2807228-A1 (DE)
Title: Electrostatic precipitator discharge strip - has zigzag shape and has to be stretched when installed for use
Inventor: WOLF HUBERT
IPC: B03C3/41
Filed: 1978-02-20
Abstract: The relevant feature of the discharge strip for electric precipitator systems is that the strip elements have a shape which allows fitting in a tensioned swingable condition without the use of additional tensioning springs. The strip is of a band material shaped in zig zag in such a way that the inital overall length is less than the distance between the points of fitting. For use the strip is fastened in a eyelet at the top of the precipitator structure and after stretching the other end is hooked in a similar eyelet (5) at the bottom of the structure and secured by wedge (6). In this condition the strip keeps taut and is easily demountable. The elongation of the strip amounts to (5) to (2)%. The angles enclosed by the elements of the zig zag shape are equal and are in the region of 50 to 100 deg.

Title: Rolling mill stock preheating system - uses furnace with three oscillating transport beams separately driven
Inventor: USHIJIMA SHIGEMI
IPC: F27B9/20
Filed: 1978-11-28
Abstract: The system heats up workpieces from a preceding continuous casting machine or rolling mill and delivers to a subsequent rolling mill working at higher speed, comprising a run-through furnace with loading and discharge conveyor. The furnace is of the re-heating type with an oscillating-beam mechanism comprising three beams each with its own drive. A set quantity of workpieces are delivered towards the discharge end of the furnace via the second and third beams at a set speed in each case, after which this quantity only are kept hot by changing the drive speed. Then a different set quantity of workpieces are loaded into the furnace after a set time interval. The first quantity kept hot, are then discharged together from the furnace, the drive speed being changed to match that of the subsequent rolling mill.

Title: Converter-fed motor control circuit - uses switching thyristor with two trigger stages for rapid changeover between driving and braking
Inventor: LAUTZ HARALD ING GRAD
IPC: H02P23/06
Filed: 1980-03-13
Abstract: The converter has two antiparallel sections connected between a three phase supply and two smoothing chokes with a capacitor between them. It is followed by a switching thyristor in series with an ohmic resistance and in parallel with the capacitor. The thyristor is connected to a pulse emitter, and forms, with the resistance, the input to the conveter section which supplies a number of variable frequency and variable voltage motors. The control system changes the motors from a driving condition to a braking condition, acting as generators. The series resistance and capacitor operate changing from braking to driving occurs only when the voltage in the intermediate rectifying circuit exceeds a given value. The control signal includes two trigger stages. The trigger stage with the smaller reaction amplitude controls the changeover system for the two converter sections and the other controls the switching thyristor.

Title: Heat pump operation system - partly separates mixture of refrigerating medium and solvent
Inventor: NEUHAUS DIETMAR
IPC: F25B23/00
Filed: 1980-03-22
Abstract: The heat pump operation system partly separates a mixture of refrigerating medium and solvent. The characteristics of the medium are such that its solubility in the solvent at constant temperature increases with increasing pressure. As the solvent absorbs the medium heat is released, while on separation of part of the medium from it heat is required.

Title: Tool producing corrugated sheets - has beads arranged to stamp corrugations from middle towards edges of sheet
Inventor: WILD ERNST
IPC: B21D13/02
Filed: 1980-06-28
Abstract: The corrugation-producing tool (10) has a vertically moving pressing plate (12) and a stationary bottom plate (14). Between the two plates an arched leaf spring (30) is placed with corrugation-producing rods (30) welded at certain distances onto the leaf spring surface. When the movable plate (12) is in its lifted position, the edges (36) of the leaf spring (30) rests on the upper surface of plate (14). On the bottom surface of the moving plate (12) another set of rods (20) is welded in such a distribution, that rods (22) and (20) miss each other, when the moving plate (12) is pressed down, while spiral springs (28) fitted on positioning pins (24) are compressed. Due to the arched shape of the leaf spring (30), it is the middle part of the metal sheet (16) which corrugated first and the corrugating deformations on the sheet progress from the middle towards the edges of the sheet as the plate (12) continues to move downwards.
