Patent DE-2310983-A1 (DE)
Title: Forging profiled rolls - billet forged first to preform then to final shape
Inventor: SCHENK HORST
IPC: B21K1/28
Filed: 1973-03-06
Abstract: A billet is clamped between dies extending along its major axis. at both ends of the dies are provided press parts. Each press part has a central core for forming a bore in the forged part. Firstly all the press parts are moved together to compress the billet into a preform. Secondly the more inward cores form the bores and force the preform metal into the cavities within the dies. The other press parts are maintd. stationery during this stage or may have been slightly retracted depending upon the degree of compression of the preform. In either case the press parts must still close the dies. After retraction of the dies and press parts the forged article is mechanically removed from the press.

Title: Pulsator for pulsed columns - having hermetic gas space behind piston to prevent egress of liquid from column
Inventor: WEIGLE DIETER DIPL ING
IPC: B01D11/04
Filed: 1973-12-03
Abstract: Pulsator for pulsed liquid extraction columns consists of piston mounted on the base of column actuated by double-acting hydraulic cylinder. The piston has circular skirt which seals against seals and is immersed in liquid seal which contains column liquid. This communicates by narrow annular gap with gas space behind piston. This gas space is connected to compressed air supply via pressure controller which maintains its pressure the same as that in the column. As the pressure is the same both sides of the piston, egress of liquor from the column is prevented. The pulsator is used in liquid/liquid transfer operations where grid or similar type columns respond favourably to pulsing. By balancing the pressure as described, a much less tight seal need be used and therefore the amount of energy required to drive the piston is reduced as well as being much better sealed in any case.

Title: Yarn breakage cutout system for knitting machine - has parallel stop and trip circuits for automatic resetting
Inventor: SPISIAK JURAJ
IPC: H03K17/60
Filed: 1974-05-06
Abstract: A knitting machine is automatically stopped in case of yarn breakages by a system of stops and a trip circuit. The system of stops is connected in series with an active element/diode rectifier, thyristor, transistor or triac) and the trip circuit is connected in series with a silicon controlled rectifier (SRC). Both circuits are fed in parallel from a common supply. The base of the SRC is coupled to the junction between the system of stops and the working element. This eliminates the possibility or overlocking yarn breakages in the case of two-core systems when the signal is small because of several parallel breakages. It requires no protective resistors or resetting keys after a breakage has been repaired. This system is very simple and reliable and responds instantaneously.

Title: Electrical transducer measuring pressure force or distance - uses capacitive inductive or resistive diaphragm operated frequency shifter
Inventor: SCHEIDT CLAUS DIPL PHYS
IPC: G01L9/00
Filed: 1975-03-15
Abstract: The electrical measurement probe uses a diaphragm type transducer (5) with capacitance, inductance or resistance element to convert the pressure, force or distance into electrical analogues. A quartz crystal-controlled oscillator (1) with constant amplitude is connected to a parallel resonant circuit filter. The filter has a sharply-defined response curve so that any small shift of the envelope either side of the oscillator frequency results in a large change in output voltage. The transducer forms a frequency-determining element of the filter so that the filter response is modified according to transducer output. The rectified output of the filter is amplified and operates an indicator calibrated to show the measured parameter.
