Title: Machine for continuous bending long bars or tubes - has bends with varying radius of curvature program controlled
Inventor: KAWANAMI SHUNPEI
IPC: B21D7/025
Filed: 1975-10-17
Abstract: The bar or tube (1) which is to be bent is passed through a set of rollers (2) (3)(4)(2')(3')(4') which are driven by an electric motor. The bar or tube (1) then passes through an induction heater (9) controlled by a transformer (10). A cooling ring (H) which directs jets of water on air on the workpiece (1) is attached to the side of the heater (9). A sliding carriage (5) supports a cross-slide (6) which supports a rotatable chuck (7) which grips the end of the workpiece (1). By controlling the speed of the carriage (5) and of the cross-slide (6) the bending moment applied to the workpiece can be controlled.

Title: Switching circuit for cooling - has single on:off valve and compressor regulated in parallel
Inventor: MOELLER WOLFGANG
IPC: F25B49/02
Filed: 1975-11-27
Abstract: The regulating circuit is used for operating a cooling system with at least one refrigerator. The compressor and a valve in the hot gas bypass are regulated according to sensed temperature in the room. The temperature sensed is compared with a desired value in the regulator for producing signals for switching the valve and the compressor. Only one on-off valve is used, and the regulator signals are not linked but transmitted in parallel for higher regulating accuracy. The regulator (11) sends a signal to a switch (12) when the actual temperature is less than the desired value. The switch energises the adjuster (7) for opening the valve (9). All further adjusting signals are fed to a switch (13) of the compressor (2). At temperatures higher than the desired value, the vale (9) is closed and signals are transmitted directly to the switch (13) for compressor switching.

Title: Fail safe protection for train brakes
Inventor: FALKE ERICH
IPC: B60T17/22
Filed: 1976-04-22
Abstract: The pneumatic brakes for the train have protection valves which monitor the airflow and which apply the brakes when a brake line breaks. In this setting the supply line is shut off from the brake line. In order to provide protection during brake venting, a time delay is operated from the onset of brake venting, reset the flow protection after a set time. - The system allows the emergency braking to operate during the brake venting sequence, especially when a brake line is cut. The supply line is shut off immediately, without having to wait for the airflow to stop, to reset the brake control.

Title: Stereophonic reproduction system - subjects channel signals to delay, phase shift and frequency change and cross-mixes signals with originals
Inventor: SCHUNKE MANFRED
IPC: H04S1/00
Filed: 1976-09-03
Abstract: The stereophonic reproduction system processes the stereo sum consisting of L and R channel signals electronically by subjecting a part of these two signals to a time delay and/or a phase shift and/or a frequency change. The resulting two signals are then cross mixed with the original channel signals with a variable level - i.e. the processed L signal is mixed with the original R signal etc. The time delay, phase shift and frequency change can be combined with one another as required. The system can also be applied to mono and quadrophonic signals.
