Title: Heat recovery and heat storage obtained from shutdown mines and brown coal pits - utilising underground and above ground parts of mines and after preparations and survey pipes are laid underground also pipe-rerouting stations with surface access
Inventor: WEBER HEINZ-BERT
IPC: F24J3/08
Filed: 1992-10-12
Abstract: The mine water courses, floor levels and seams are established, with some blind shafts closed and others left open. A hydraulic short circuit is prevented. In mines not flooded air can be used as a carrying medium. The heat pumps are installed above ground. Pipes or pipe bundles are laid before the mine is filled or flooded, so that they can be checked and replaced when necessary. The carrying medium e.g. eater is better heated over long distances, and heating pumps with the highest possible heat output are used to maintain a constant temp. through the year. This heat is transmitted to end users. Waste heat available from power stations also exhaust water from heat cooling towers can be utilized. ADVANTAGE - Economic use can be made of pits, mines, dumps, quarries and associated plant and buildings. Systems used are environmentally friendly.

Patent DE-4303386-A1 (DE)
Inventor: VOGT LOTHAR DR
IPC: H03G5/00
Filed: 1993-02-05
Abstract: In a circuit arrangement for digital processing of audio signals in a radio receiver, preferably in a car radio, the audio signals traverse a digital filter which is constructed as a sound control and whose frequency response can be controlled by means of supplied coefficients, and a volume control whose transmission coefficient can be controlled by means of supplied manipulated variables. In this case, if the high and/or low frequencies are raised the transmission coefficient of the filter can be correspondingly lowered for middle frequencies. The lowering is compensated by the volume control. The volume control can have a digital and an analogue part. <IMAGE>

Patent DE-4317890-A1 (DE)
Title: Method for operating an optical resonator and optical resonator arrangement
Inventor: DESERNO ULRICH DR
IPC: G02F1/35
Filed: 1993-05-28
Abstract: The object is, in the case of optical resonators, to prevent frequency noise. Particularly low frequency noise can be achieved with a regulation process in which the working point does not lie at the maximum of the resonance curve of the resonator, and in which regulation for the working point is carried out with the aid of the ratios of a portion, reflected by the resonator, of the radiation power fed to the resonator and of a portion, extracted from this radiation power and proportional to this radiation power. Low frequency noise can also be achieved if the optical path, on which the optical radiation power, emitted by the optical transmitter and intended to be fed to the resonator, is fed back does not contain optical isolators but instead itself defines an optical resonator which is short enough for the separation between its resonance lines to be comparable with the separation between the resonance lines of the actual resonator and/or the emission lines of the transmitter, and can be altered in length in a controlled manner, as a result of which stable states of the arrangement can be produced. Optical frequency doubling.

Patent DE-4343855-A1 (DE)
Title: Detecting state of fluid esp. gas
Inventor: BARTH HANS-JOERG PROF DR ING
IPC: F23N5/00
Filed: 1993-12-22
Abstract: The method involves measuring at least the temp. of the fluid as a state parameter. The speed of sound in the fluid is measured and the temp. derived from it. The speed of sound is measured from he transition time of sound from a source to a receiver at a known distance from it. The sound signal propagation speed is derived from the measured transition time and the known distance. For measuring the speed of sound in a flowing fluid, two transmitter/receiver pairs are used. These are arranged to enable the transition times to be measured in and against the flow direction. The difference in transition times gives the speed of sound.

Title: Valve gear for a cam-actuated lifting valve fitted with closing spring
Inventor: KUENNE ERNST-ANDREAS DIPL ING
IPC: F01L9/11
Filed: 1994-07-30
Abstract: For obtaining a transmission ratio between cam (38) and valve (37) a valve gear for a lifting valve (37) contains a pressure chamber (32) in a component (30) designed for the introduction of the valve actuating forces of the cam (38), which chamber transmits the valve opening forces by way of a valve actuating piston (34), displaceable in the valve actuating direction, and a further pressure chamber (33), which is defined by a fixed displacement piston (35). The displacement piston (35) has a larger piston surface than the valve actuating piston (34), so that in valve opening movements pressure medium is transported out of the further pressure chamber (33) into the pressure chamber (32) by way of a connecting passage (31), displacing the valve actuating piston (34) in the valve opening direction. As a result, a higher valve lifting curve is obtained than inherently predetermined by the cam path. By restricted removal of pressure medium from the further pressure chamber (33) when a valve (41) is in the opened position, the valve lifting curve can moreover be influenced as a function of the engine speed (Fig. 3). <IMAGE>
