Patent DE-19521251-A1 (DE)
Title: Cooling device e.g. for removing heat from switching- or electronic cell
Inventor: SCHMIDT FRIEDRICH HARALD
IPC: H05K7/20
Filed: 1995-06-10
Abstract: A device to cool a space cell (1) uses a surface heat exchanger (2), located on the inner walls of the cell. Its front side(3) serves for the radiation exchange and free convection. Its back side (4) is used for the removal of warm air from the cell using the recirculation principle. The surface of the front side is connected to that of the back side by connectors with at least one parallel tube shell in which the tube (5) for the thermal transport of the cooling medium is inserted so as to be conducting. The surfaces of the front side and back side also have parallel air channels.

Title: Noise reduction method esp. of ambient noise in hands-free speech telephone terminal device - selecting special call number or identifier for calling-up noise reduction system, via digital telephone network, which is then connected to terminal device via telephone system
Inventor: ZELINSKI RAINER DR ING
IPC: H04M9/08
Filed: 1995-07-05
Abstract: The method involves selecting a special call number or identifier for calling-up a noise reduction system via the digital telephone network. The noise reduction system is then connected to the terminal device via the telephone system so that the ambient noise signal superimposed onto the speech signal at the hands-free speech microphone, and any echo signal, is suppressed during the connection to a remote subscriber when hands-free speech mode is selected. If echo suppression is not adequate, a further identifier is output to the telephone system which drives an echo cancellation system within the digital telephone system. The echo cancellation system is then connected to the terminal device in addition to the noise reduction system.
Patent DE-19530809-A1 (DE)
Inventor: HINDERLING JUERG DR
IPC: G02B5/122
Filed: 1995-08-22
Abstract: The invention relates to an arrangement for retroreflection of an optical ray using triple prisms. Six to ten triple prisms (1, 2, 3, 131, 132, 133) are provided with triangular light entry surfaces, wherein the side faces of adjacent triple prisms are in contact. This results in continuous retroreflection at a high level of intensity for one angle area, of 360 DEG . When used in particular in geodesy or in construction surveying, this all-round reflector provides a high degree of measurement accuracy for angles and distances from any direction on which a bearing is taken. Alignment towards a surveying instrument is therefore not necessary. Measurement of short distances is also definite and reliable. The all-round reflector is particularly advantageous for automatic surveying, since, irrespective of its orientation, it can be automatically tracked by a motorised surveying instrument.

Title: Method for feeding electrical or optical conductor into very long conduit
Inventor: POREMBA JOHANNES DIPL ING
IPC: G02B6/44
Filed: 1995-10-14
Abstract: A method for feeding electrical or optical conductors (13) into very long conduits (1) divides the conduit into eg. three lengths (8,9,10) where each breakpoint (5,6) is readily accessible. The conductor (13) is drawn from its reel (21) at the breakpoint (5) by a traction mechanism (23) which feeds it through the conduit (9) up to the second breakpoint (6) where it is laid up in figure-of-eight format (20) using the tripod (26) before it is pushed or drawn by a compressed air (22) piston (not shown) through the conduit (10). The reel (21) is now fully unwound repeating the figure-of-eight lay and the conductor's opposite end (not shown) is moved through the conduit (8) as previously.

Title: Regional measurement of transparency of colour photographic negative
Inventor: HARTMANN KLAUS-PETER DR
IPC: G01J3/51
Filed: 1995-11-13
Abstract: The method employs a halogen lamp (1) with a reflector (2) and a double condenser lens (3) enclosing a matt glass filter (4) for thermal protection. An optical fibre bundle (7) conveys the convergent beam to a rectangular exit surface (7a) as broad as the film strip (9) to be scanned.

Patent DE-19547832-A1 (DE)
Inventor: STARK THOMAS
IPC: G01P3/48
Filed: 1995-12-21
Abstract: The device determines the rotation rate of a combustion engine (1) connected to a generator (2). The engine has a known number of cylinders and an known operating principle. The generator is driven by the combustion engine with a fixed transfer ratio. The device determines the rotation rate of the combustion engine from the waviness of the DC generator voltage supplied to the on-board mains (3). The device automatically determines the transfer ratio between the generator and the engine in a one-off learning phase. In this phase the digitised component of the DC output voltage of the generator is transformed into the frequency range. The device determines the ratio of the frequency with maximum power density to the lowest frequency as the transfer ratio between the generator and the engine. Other components are bandpass filter (4), amplifier (5), A-D converter (6) and digital assembly (7) for signal processing.

Title: Combined cement and sulphuric acid production
Inventor: REIMANN GOETZ
IPC: B03B9/06
Filed: 1996-06-26
Abstract: A method of cement and sulphuric acid production by the Muller-Kuhne process involves decomposing CaSO4 in a mixture of residues and cement starting material powder and/or chemically reactive carbon in a rotary kiln, firing the CaO at above 1200 deg C in the presence of SiO2, Al2O3 and Fe2O3 to form cement and reacting the SO2-containing flue gas to form SO3 or H2SO4. The novelty is that dry gypsum board and other gypsum rubble are pre-reduced to a uniform mill-processable edge length, sorted and freed from foreign materials such as wood, steel and plastic pieces, ground to powder fineness under throttled air suction, mixed with other cement starting material powder components and, after optional intermediate storage, processed in the rotary kiln while supplying tertiary air. Also claimed is a plant for carrying out the above method.

Inventor: RADEMACHER BERND
IPC: A61C13/235
Filed: 1996-07-31
Abstract: The invention concerns a locking device (1) for releasably mounting a dental prosthesis (2) to a primary element anchored to the teeth. The device has a locking element (5) mounted so that it can move longitudinally in an axial direction within a housing (3). The locking element (5) has a permanent magnet (7) at one end. The housing (3) almost completely surrounds the locking element and is encircled by the prosthesis (2). The housing (3) provides protection against the magnetic radiation emitted by the permanent magnet (7) but allows a magnetic flux (20) to pass through. The locking element (5) is moved with the help of a control magnet (22) by using the force fields which arise between the two magnets (7, 22). The locking element (5) can thus be activated without contact.
