Patent DE-3002127-A1 (DE)
Title: Outlet for electrical fine wire connections from pressure vessel - is through cast seal which is compressed by pressure inside vessel
Inventor: SCHWIND HERMANN PROF DR ING
IPC: H01B17/30
Filed: 1980-01-22
Abstract: The application is typically to leads from measuring elements, for example strain gauges, inside a pressure vessel. The proposed method of sealing is intended for use at internal pressures up to 4000 bar. A small hole (8), large enough to take the leads (6), typically at least twelve, is drilled through the pressure vessel wall. On the inside this hole is opened out by a conical counterbore (9). The leads (6) are spaced out on the inner side and the counterbore largely filled with a two part sealant. The leads are threaded through individual holes in a flanged bush (11), which is then clamped down onto the seal to give some precompression. As the internal pressure is increased the precompression of the seal prevents any leakage. As the pressure rises further the flanged bush exerts a further pressure on the seal. As the outlet hole is very small in diameter there is no tendency for the sealant to be extruded at pressure up to 4000 bar.

Patent DE-3107187-A1 (DE)
Title: Compressed-air engine
Inventor: SCHWEIKERT EUGEN
IPC: F03G7/10
Filed: 1981-02-26
Abstract: The invention relates to a compressed-air engine, combined with oil or water, principally for stationary applications and, in the case of series connection of four or six such scissors elements next to one another, would be comparable to a four- or six-cylinder engine. It could also be used on land or water or in the air and in all branches of industry as well as in every home. The intention is to provide an energy source which is above all ecologically beneficial and solves all energy problems. The four relief supports or, alternatively the four threaded spindles have the task of holding the load until the scissors elements have returned to their initial position - at this moment, the scissors elements will take over the load again - and a new work cycle begins. The entire redirection of the load is accomplished via the slider linkage (13). The scissors elements change by just 2 cm, not from the top downwards but from the bottom upwards. This is made possible by the ramps (2, 2a) and thereby results in a forward thrust of 10 cm and, via a connecting rod/crankshaft/flywheel, a rounding movement.

Patent DE-3137497-A1 (DE)
Inventor: KEIL HEINRICH DIPL ING
IPC: H04B17/00
Filed: 1981-09-21
Abstract: A desire exists in the optical transmission of optical signals to co-transmit a service channel or telemetry signals in the form of an additional low frequency signal over the light conductor, since a remote feed line or a service channel is not always installed parallel to the light conductor length. The requirement exists for the transmission of the additional signal that, in addition to a low additional expense, no disruption of the actual useful signal can occur. To this end, the control signal of a laser diode transmitter is modulated with the signal to be additionally transmitted and this light component is coupled out at the receiving side. The structure is particularly useful in optical transmission systems for very high frequency digital signals with bit rates above 100 Mbit/s.
