Patent DE-3141420-A1 (DE)
Title: Hearing aid
Inventor: SCHLOSSER HELMUT DIPL ING
IPC: H03G5/04
Filed: 1981-10-19
Abstract: The invention relates to a hearing aid whose amplifier (6, 8) contains a frequency filter (7) comprising two signal paths (7a, 7b) which are designed as a sound rocker, in which the frequency response of the transmission range can be influenced by means of just one operating element. According to the invention, one signal path is designed as a broadband channel (7a) and the other as a high-pass filter (7b) in order to extend the efficacy of the rocker in the frequency filter (7). In one path, the signal is phase-shifted at least approximately through 180 DEG  in relation to that of the other path. Furthermore, a controller for the intensity of the signal passing through is provided in one of the paths as an operating element (24, 73) of the sound rocker. In addition, the broadband channel (7a) contains passive components only and can transmit signals in both directions so that it can also act as a negative feedback branch. Through modification on the operating element (24, 73) in the vectorial summation of the signals from both signal paths (7a and 7b), it is thus possible to achieve a low-frequency reduction of 12 to 18 dB/oct. and a high-frequency reduction of 6 dB/oct. A hearing aid with a sound rocker with efficacy extended according to the invention is particularly suitable for use as an auditory prosthesis. <IMAGE>

IPC: F02C3/20
Filed: 1981-10-29
Abstract: A gas turbine power plant (10) has a pressurised combustion chamber (12) with turbulently fluidised fuel in which fuel is burnt in order to produce combustion gases. In addition the power plant has a purification system (14) which receives the combustion gases from the combustion chamber and removes the pollutants carried in the combustion gases. Finally the plant also has a gas turbine/air compressor sub-system (16) with a gas turbine (48) to which combustion gases are fed from the purification system, which combustion gases drive this gas turbine and through this an air compressor (46) and a load, such as, for example, a power generator. In the lines which interconnect the combustion chamber, the purification system and the gas turbine/air compressor sub-system valves are provided in such a way that the combustion chamber and the purification system can be isolated from the gas turbine/air compressor sub-system. For the combustion chamber and the purification system, a venting device is provided by means of which the pressure in the combustion chamber and in the purification system is relieved after these have been isolated in order thereby to permit inspection and/or repair of the combustion chamber and the purification system whilst at the same time generating energy. <IMAGE>

Patent DE-3310888-A1 (DE)
Title: Use of liquid soap
Inventor: HOMPESCH KARL
IPC: C10M173/02
Filed: 1983-03-25
Abstract: Very expensive hydraulic oils, lubricating oils and transmission oils for the transmitting of pressure (static and dynamic) have become indispensable in present-day technology. The attempt to replace the costly oil by water has remained limited to only very narrow fields of use. By the invention, the oil previously used is to be replaced in wide fields of technology by a substantially cheaper fluid having comparable properties with regard to its technical effects. For this purpose, the invention proposes the use, instead of the customary hydraulic or lubricating oils, of liquid soap with or without additives as a pressure-transmitting fluid and as a lubricant in hydraulic systems, hydraulic pumps, hydraulic jacks, mechanical transmissions, hydraulic transmissions and clutches (converters), as well as, in general, as an alternative for hydraulic oil, transmission oil and lubricating oil and as a fluid for use in fluid-wetted air filters.
