Patent DE-2557495-A1 (DE)
Title: Quadrophonic system with signal sum and difference techniques - uses left and right and front and rear signals to give three:channel signals
Inventor: HIEMANN KLAUS
IPC: H04S5/02
Filed: 1975-12-19
Abstract: The quadrophonic system, with two front and one rear channels, produces a quadrophonic signal from a three-channel signal and vice versa. A left 3-channel signal is obtained by summing components of the left front and rear channels, and a right 3-channel signal is obtained by summing components of the right front and rear channels. The third 3-channel signal is obtained from the difference between the front and rear left or front end rear right signals. The so-formed 3-channel signals are converted into quadrophonic signals by constructing sum and difference signals to obtain the original four signals.

Title: Coke oven charging wagon with cover lifter - rotates cover between tools on table for automatic cleaning operation
Inventor: BLASE MANFRED
IPC: C10B43/06
Filed: 1976-04-28
Abstract: A coke oven charging wagon fitted with a lifting arrangement for the covers of the retort inlets, has, also on the wagon, a table on which the inlet covers may be deposited by the lifting arrangement. On the table, cleaning tools, e.g. scrapers, wire brushes, are fixed in a circle and the lifting arrangement rotates the cover between them for cleaning. This does away with the inconvenience and waste of time involved in depositing the covers for cleaning alongside the charging holes. In the routine during which, after the coke has been pushed out, the cover is removed to admit air to burn away the graphite, with the wagon returning to the tower to be filled with coal, a journey to pick up the cover from the top of the retort is saved. The cleaning of the cover is no longer a manual operation.

Title: Speed limiting system for vehicles - has speed dependent servo adjusted throttle stop set according to tachogenerator
Inventor: RATHERT HORST ING GRAD
IPC: B60K31/02
Filed: 1976-07-03
Abstract: The engine speed is limited by an accelerator pedal stop (4) displaceable by a servo unit (1). The accelerator pedal is connected to the servo by a connecting red containing an extendable part (2). An accelerator rod movement recorder (5) shows the actual accelerator position stop (4) when the extendable part is not extended. The movement recorder (5) output is fed to a regulator (13). The regulator receives an actual speed signal from a tacho generator and a max. value setting (14). When the max speed is reached the servo motor (1) exercises a return force to the accelerator pedal which can be overcome by manual force.

Title: Butt welding glass pipes without pipe rotation - using hollow support in bore and vacuum or pressure to prevent dimensional change
Inventor: ECKARDT PETER DIPL CHEM DR
IPC: C03B23/207
Filed: 1976-07-23
Abstract: Glass tubes or pipes are butt welded, esp. without using rotation, where the joint surfaces are heated, pushed together, and then drawn slightly apart. Before welding, a hollow body, e.g. a cup which does not bond to the glass, and which has an outer dia. slightly smaller than the bore of the pipes, is inserted at the joint. A plug (a) is inserted in one pipe, whereas a plug (b) contg. a flexible tube is inserted in the other pipe, so a reduced pressure can be established in the bore after pushing the pipes together, whereas a press. above atmos. can be used after drawing the pipes apart. A cable is pref. used to pull the two plugs and the cup out of the pipes after welding. In the pref. appts., one pipe is held in a stationary clamp, and the other pipe in a driven clamp. Both clamps are fitted on a rail supporting a hinged ring burner fitting round the joint; and a spring-loaded device is employed to smooth the outer dia. of the weld.
