Title: Flue gas purification with simultaneous neutralisation of the acid formers present in the atmosphere
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/34
Filed: 1984-11-27
Abstract: It is known that a considerable acid-former pollution results not only from domestic industrial plants but also from those of neighbouring countries. In order to at least substantially reduce these pollutions, according to the invention it is proposed, to reduce the acid formers, to feed neutralising agents to a cooling tower above its mist eliminator and beneath its mixing device, and thus to the atmosphere. The neutralising agents are added to the scrubbed flue gases prior to their introduction beneath the mixing device into the cooling tower. Measuring devices are erected near the ground in the vicinity of the cooling tower exhaust air volume expansion, which measure the air and/or the moisture content of the air and/or the precipitation, evaluate the results and influence, via a process computer, the addition of neutralising agents into the cooling tower in a controlled manner.

Title: Heat pump from the electricity network
Inventor: SCHROEDTER ROLF DR ING
IPC: F24H3/00
Filed: 1985-02-06
Abstract: In an evaporator boiler, a heat transfer medium is heated and evaporated by means of heating resistance which condenses the vapour in a condenser or heating body in order to deliver its condensation heat and flow back into the evaporator as condensate. In this case, a heat transfer medium with relatively high evaporation temperature is used, for example water/water vapour.

Title: Tennis racquet
Inventor: BUSCHBECK PETER
IPC: A63B51/01
Filed: 1985-02-21
Abstract: The tennis racquet has a string woven from longitudinal and transverse strings (12), the individual strings each being secured to the frame (10) at both ends by means of fixing elements (16) and being split adjoining the fixing point. The fixing elements used are clips (16) which can be clamped on the strings (12) and become wedged as a result of their tension in the holes (14) in the frame (10). The mesh of the longitudinal and transverse strings (12) is prefabricated. All that is then necessary during assembly is that the free ends of the strings (12) be passed through the holes (14) in the frame (10), tensioned and fixed by means of the clips (16). <IMAGE>

Title: Pulse-based fluorometer
Inventor: SCHREIBER ULRICH DR
IPC: G01N21/64
Filed: 1985-05-23
Abstract: The invention relates to a pulse-based fluorometer which is capable with the aid of a selective pulse-amplifying system of detecting rapid variations in the fluorescence yield in the case of irradiation by strong, unfiltered white light. The measurement system comprises a periodically pulsed light source, e.g. a light-emitting diode, for fluorescence excitation, a photodetector, e.g. a photodiode, for detecting the fluorescence pulses and a pulsed-amplifying system which processes the fluorescence pulse signals selectively even against a large background of superimposed signals. The fluorometer is particularly suitable for measuring the light-induced variations in the chlorophyll fluorescence of living plants in the event of exposure to unfiltered strong light, e.g. sunlight.

Title: Plug connection for electrical cables
Inventor: GNAUERT ROLF DIPL ING
IPC: H01R24/58
Filed: 1985-08-20
Abstract: Such plug connections have until now consisted of plug pins on one cable end and plug sockets on another cable end or on an apparatus connection. The plug pins in consequence form projecting parts and, to a great extent, are subject to the risk of damage, especially in underground mining operations. The defects and disadvantages associated therewith are avoided according to the invention in that a plug 25 is now provided which is independent of the cable, has two contact pins 26 at the ends and is not inserted into the plug sockets 2 until two cables 1 are coupled, a cable 1 is connected to an apparatus, or two apparatuses are coupled directly. Such a plug 25 can be handled easily and can be replaced without problems. There is no need to carry cables from underground to the surface for repair. <IMAGE>

Title: Engine for converting thermal energy into mechanical energy
Inventor: ECKERT REINHARD
IPC: F02C7/141
Filed: 1985-09-18
Abstract: A new engine is described for converting thermal energy into mechanical energy. This engine has a cold machine part for the compression of a flow of a gaseous substance and a hot engine part. The thermal energy is generated outside the working chambers of the engine part. The machine part and the engine part are thermally separated from one another. As a result, the compression in the machine part and the expansion in the engine part can each occur virtually isothermally. The machine part is normally driven by the engine part. In particular operating conditions, for example in the starting process or in the absorption of brake energy, the machine part and the engine part can be separated from one another. The flow of the substance compressed in the machine part is used as combustion air in the engine part.

Title: Process for purifying cooling lubricants
Inventor: MUELLER HANS-JOACHIM
IPC: C10M175/00
Filed: 1985-10-21
Abstract: For purifying liquid, in particular mineral oil-based, cooling lubricants, which are preferably circulated continuously in chip-forming installations, surface-active and adsorbing substances, such as preferably commercially available bleaching earths, are used as filter aids in precoated filters built into the circulation. The liquid cooling lubricants are thereby purified by the removal of both solid abraided particles and harmful substances which have been formed and dissolved, so that the cooling lubricants can be fed even at high throughput and fresh oil quality to the metal-working installations, and the latter continuously run virtually without losses and hence economically.
Patent DE-3541338-A1 (DE)
Title: Circuit having self-monitoring
Inventor: NEUGEBAUER VICTOR DIPL ING
IPC: H01H47/00
Filed: 1985-11-22
Abstract: The invention relates to a circuit having self-monitoring, in the sense of a fail-safe circuit. In the case of known circuits of this type, there is a relatively high cost for relays having positively-guided contacts, relatively high excitation powers being demanded and there being problems which counteract miniaturization. The invention indicates the means for overcoming these disadvantages, allowing the switching contacts of the operating circuit to monitor themselves and these switching contacts to be included in the excitation circuit in the quiescent position.

Patent DE-3543128-A1 (DE)
Inventor: BREITWEG WERNER
IPC: B21J5/12
Filed: 1985-12-06
Abstract: A single piece valve box for a rotary slide valve has on its inner circonference axial control grooves (3) of which the axial length is delimited by the surface of the inner circonference. Said valve box is produced by forming from a flank, for example a pipe section. In a first step, the control grooves (3) are shaped by cold forming so that one of their ends (4) is closed and the other end (5) is open. The open ends of the control grooves (3) are terminated in a partial bore (6) having a larger diameter. A collar (8) having a larger outer diameter is formed on the contour of the valve box at the partial bore (6). In a second step, said collar (8) is pressed inwardly by cold forming till the inner diameter corresponds in that region also to the inner diameter of the remainder of the valve box, thereby closing the other end of the control grooves (3).
