Title: Hydraulic shift device without linkage for a mechanical transmission in motor vehicles
Inventor: SORG JOHANNES ING GRAD
IPC: F16H61/30
Filed: 1981-07-17
Abstract: For transmitting the selection and shift movements in a shift device without linkage for mechanical motor vehicle transmissions the two piston chambers of the master cylinders (11 and 14) mechanically connected to the gear shift lever (1) are each respectively connected by pressure medium lines (12.2, 12.3 and 14.2, 14.3) to the piston chambers of the slave cylinders (12 and 15). At the same time the piston rods (5a and 7) of the slave cylinders are connected to the gear shift shaft (5) of the transmission (8). In order to obtain proportionality between the shift force or the shift travel at the gear shift lever (1) and the sliding sleeve in the transmission (8), servo cylinders (13 and 16) are arranged on the piston rods (5a and 7 respectively) of the slave cylinders (12 and 15) and the piston chambers of the servo cylinders are each connected by way of a valve device (17 and 18 respectively) to a pressure medium source (19) for gear selection and gear shifting. The valve devices (17, 18) each have a four/three and three/two way valve (17.1, 17.2 and 18.1, 18.2), which are joined by pressure ducts (14.4, 14.5 and 11.3) to the master cylinders (11, 14) for the purpose of actuation. In this case the three/two way valves are connected to the pressure medium source (19) by way of pressure limiting valves (17.3 and 18.3) and respective two/two way valves (17.4 and 18.4) with a closed zero position. <IMAGE>

Patent DE-3230765-A1 (DE)
Title: Diving device
Inventor: RAIDA JOACHIM
IPC: B63C11/20
Filed: 1982-08-16
Abstract: A diving device, with the aid of which it is possible, using the water pressure and the lung power, to compress fresh air in a container above the water surface and to convey it to the desired water depth into a breathing bag. The device is an exclusively pressure-controlled system which in its above-water part firstly uses exhalation air for compression of the fresh air. Over and above the pressure equalisation, the lung pressure then moves the fresh air into the breathing bag under water. On the escape of the spent air, the latter draws fresh air into the compression container again. An arrangement of valves on the above-water and the underwater part guides the air through hoses in the required directions. The device consists of three elements: the above-water part (breath pump) which floats on the water surface, the underwater part with the breathing bag which the user wears fixed to his body, and the hose connections, through which the fresh air and the outgoing air are conducted. The system functions without outside energy, only by using the pressure fluctuations during breathing.

Title: Internal axis rotary piston machine having a circular housing contour and suitably curved piston end surfaces as a heat engine which can be used universally
Inventor: SPEIDEL KARL ING GRAD
IPC: F02B55/00
Filed: 1982-09-03
Abstract: In the opinion of the inventor and a number of relevantly experienced physicists and machine constructors, it is clear from the Main Application dated 24 July 1982 and the additional applications dated 25 August 1982 and 1 September 1982 that the novel rotary piston machine offers such impressive advantages in comparison with all the systems which have already become known, not least including the WANKEL rotary piston engine, that it will be the first rotary piston machine which will be able to be considerably superior to even the most modern reciprocating piston machines in virtually all criteria. This prognosis applies to all the performance regions from aircraft model and ship model drives to multi-housing large machines with a maximum power of approximately 6000 kW. The extremely low weight per unit power means that it is expected to be possible to break into the field of relatively small to medium-size aircraft drives, which have been the province of gas turbine engines for years. An application in military land vehicles or water vehicles promises to be highly successful and initial discussions so far with the Federal Ministry of Defence have proved positive. The simple method of construction, which is easy to understand even by a layman having technical understanding, necessarily leads to highly favourable production and maintenance costs, which also makes the subject-matter of the invention interesting for developing countries. This aspect is supported in that the rotary piston machine can also be designed as a hot-air or helium engine with a closed operating process which ... Original abstract incomplete.
