Patent DE-2008249-A1 (DE)
Title: Rotary multistation press
IPC: B21K1/46
Filed: 1970-02-23
Abstract: Horizontal multistation press consists of a main cylindrical rotating mounting element. It has a constricted diameter portion in the centre and is rotated via a direct spur gear drive engaging a tooth profile on its O. near its two ends. Into this element are drilled wto diametrically opposite axially parallel holes on a fixed radius from the centre of the element. In these are mounted in one half reciprocable cylinders extending from beyond the outer end into the centre portion, where dies are mounted in them each die having two bores. At their other end they have a round knob shaped end which is running in a ring with a corresponding groove mounted at an oblique angle to the axis of rotation of the mounting element thus, that the die holding cylinders reciprocate when this rotates. In the other half of the mounting element are mounted the punch guides facing the dies. In these are reciprocating the punches which are mounted similarly to the dies in punch holders which are reciprocated. THe workpieces are introduced from the side into the punch holder and are pushed forward by the punches into the working position.

Title: Cyclotron control circuit - for positional monitoring of particle stream
Inventor: NIEDEREDER MARTIN DIPL-ING
IPC: G01T1/29
Filed: 1970-12-10
Abstract: Control circuitry for a cyclotron a particle accelerator monitors the particle stream and establishes positional co-ordinates for the particles. A series of probes are arranged separately and circumferentially around the cyclotron and connected to a central station. Voltages of a frequency equal to the accelerator frequency are induced in the probes and relayed to the central control station. Within the control circuit the probe induced voltage outputs are alternated with a pilot voltage and their frequencies transposed to an intermediate frequency, rectified and an output voltage relative to their amplitude difference established. This final output for all probes is then fed to a summator which determines X-Y co-ordinates for the particles.

Title: Off-gas sampling - esp during pig iron refining with separation of flue dust
Inventor: HAGER ALOIS DIPL ING
IPC: G01N1/22

Title: Frequency multiplier cct. - two same frequency voltages with ninety degrees phase difference are applied to two channels
Inventor: LAUCKNER GERALD DIPL ING
IPC: H03B19/00
Filed: 1973-11-24
Abstract: Two voltages of twice and frequency, whose phases differ by 90 deg., can be collected at the circuit output. The first channel contains a multiplier, and the second two summators followed by a multiplier stage. The error portion of each calculating operation is split equally between both channels. The signal potentials delivered by a piece of apparatus are conducted to the inputs of the summation stages, and added or subtracted before reaching the multiplier stage. Most similar frequency multipliers have more stages, e.g. two multiplier stages in the second channel, causing a further error portion. The error of a summator amplier is noticeably smaller than that of a four quadrant multiplier.

Title: Check valve for explosion protection in gas pipe - has spring-loaded plug retained by fail safe strip
Inventor: HOELEMANN PAUL DR
IPC: F16K17/40
Filed: 1974-07-31
Abstract: The check valve in a gas pipe acts as protection against the propagation of an explosion wave. The tubular valve body (1) has an insert with a tapered valve seat (3). An internally tapered plug (2) is held open in an axial position by a heat sensitive solder strip (7) against a prestressed compression spring (5). When a pressure wave, due to an explosion, arrives at the check valve, the solder strip is torn and the plug (2) is pressed over the valve seat taper (3), thereby closing the pipe. Similarly, if the gas temperature rises above a certain level, the solder strip fails and so closes the pipe.
