Title: Method and device for protecting an oxyacetylene torch
Inventor: STOCKER JOHANN DIPL ING
IPC: F23D14/76
Filed: 1984-10-10
Abstract: The invention relates to a method for protecting an oxyacetylene torch against damage by flashback, a fuel gas being mixed with oxygen or with an oxygen-containing gas in the mixing zone of the oxyacetylene torch and the mixture being burned. In order to relieve the operating personnel and to exclude to a great extent damage of the oxyacetylene torch in the event of a flashback, it is proposed to measure the temperature in the region of the mixing zone and to interrupt the supply of the gases to the mixing zone as soon as the temperature in the region of the mixing zone exceeds a predetermined temperature level.

Title: Sound absorber for sewage-conveying means
IPC: E03F1/00
Filed: 1985-02-13
Abstract: In pneumatic sewage-conveying means, due to operation large volumes of compressed air have to be expanded to atmospheric pressure in a short period of time. This release leads to considerable noise disturbance. To prevent this noise disturbance, a sound absorber for an expansion line of a pneumatic sewage-conveying means is provided which comprises a housing having deflection devices which are arranged transversely to the direction of through-flow, are arranged alternately on different sides of the housing and leave in each case a part of the through-flow cross-section free. This sound absorber has an in-flow opening and an outlet. The housing is at least partially filled with gravel and the gravel filling extends, on at least part of the length of the housing, over the entire through-flow cross-section.

Title: Device for detecting the effective dielectric constant of a medium, particularly for determining the water content in a filled container for oil or alcohol
Inventor: NESKE EUGEN DR
IPC: G01N33/28
Filed: 1985-05-21
Abstract: A device for detecting the effective dielectric constant of a medium is used, in particular, for determining the water content of an oil-water emulsion and the height of the boundary area between a water layer and oil layer in a tank. The device has a receiving electrode (7) surrounded by an insulator, which is connected to the input of an evaluating device operating frequency selectively and phase selectively. The receiving electrode (7) is associated with field-generating first and second transmitting electrodes (5, 6) to which alternating voltages with opposite phases are applied via first and second drive amplifiers (10, 11). The amplitude ratios of the alternating voltages are adjusted with the aid of a null correction circuit (21, 24) in such a manner that the currents induced in the receiving electrode (7) by the transmitting electrodes (5, 6) compensate one another. The receiving electrode (7) is shielded against the alternating electrical fields generated by the first and second transmitting electrodes (5, 6) on at least one side, a third transmitting electrode (9), which is connected to the voltage of one of the drive amplifiers (11) via a switch (13, 14), being arranged in the area thus shielded. The space existing between the third transmitting electrode (9) and the receiving electrode (7) forms a measuring space (8) for the medium to be examined. <IMAGE>

Title: Method and device for measuring the human ankle bone and for stretching ski boots according to the human ankle bone
Inventor: LUTZ NORBERT
IPC: A43D5/00
Filed: 1985-06-26
Abstract: The invention relates to a method and a device for measuring the human ankle bone and for stretching ski boots according to the human ankle bone. By means of a measuring device, which consists of transparent plexiglass, like in a visor, the exact ankle position is determined by means of a coordinate arrangement. The coordinate number thus determined is transmitted to a device which is provided with the same coordinate arrangement. With different attachment parts, the ankle position thus previously determined is reconstructed accurately on the stretching device. The ankle dummy (stretching device) is then introduced into the previously heated ski boot and the ski boot is closed. The heated plastic material is plastically deformed and assumes the shape of the ankle or ankles.

Abstract: In a process for producing alpha-hemihydrate gypsum from calcium sulphate dihydrate from flue gas desulphurisation plants operating by the wet scrubbing process with lime, a suspension, taken off from the flue gas desulphurisation plant and containing the calcium sulphate dihydrate, and, if appropriate, auxiliary substances, are continuously introduced from above into an upright tubular reactor, the suspension is heated in the reactor to a reaction temperature which is higher than 100 DEG C but lower than the boiling point, and finally an alpha-hemihydrate gypsum suspension is taken off from the bottom of the reactor. The liquid level in the reactor is adjusted by means of control instruments in the reactor outlet. The suspension is heated in the reactor by steam which is introduced into the suspension. The heating with steam is effected at a plurality of points uniformly distributed in the longitudinal direction. A reactor for carrying out the process is described. <IMAGE>

Title: Method and device for data transmission
Inventor: HOFF ADELBERT DIPL ING
IPC: G06F13/40
Filed: 1986-02-03
Abstract: The essential feature of the invention is the division of the address bus of the signal processing unit into a first part for control and addressing, and a second part (called the data address bus) for transmission of signals to an external device. The division into a control part and an addressing part is basically necessary because the external device has to distinguish whether the signals at its ports are transmitted to the external device or not. For this purpose, at least one control or address line is necessary. Therefore, if the number of signals (data, addresses and/or control signals) to be transmitted to the external unit simultaneously is not greater than the width of the address bus of the signal processing unit minus one, the parallel transmission method can be used. If another control or address line is provided, it is possible to distinguish between a call of the control and addressing device of the data transmission unit and a call of the external device. s - 2 lines are available for control and addressing and for transmission of signals to the external device. Also, the alternating transmission method can be used for transmission of signals. If other divisions of the address bus of the signal processing unit are chosen, the signals can be in either parallel or word-serial ... Original abstract incomplete.

Patent DE-3607301-A1 (DE)
Inventor: HERBRECHTSMEIER PETER DR
IPC: B29D11/00
Filed: 1986-03-06
Abstract: Optical waveguides of plastic usually consist of a core and a jacket, the core material having a higher refractive index than the jacket material. A suitable core material is a fluorine-free polymer and a suitable jacket material is a fluorine-containing polymer, which can also contain deuterium. The optical waveguides can be produced by passing a polymer rod through a solution of the jacket polymer and then removing the solvent. The optical waveguides are particularly suitable for the transmission of data with the aid of light waves with a wavelength of 500 to 750 nm.
Patent DE-3608778-A1 (DE)
Title: Method and grinding tool for the precision cylindrical grinding of shafts
Inventor: PLETTKE HERMANN
IPC: B24B35/00
Filed: 1986-03-15
Abstract: The invention relates to a method for the precision cylindrical grinding of shafts made of hard materials, in particular steel. Known methods require a very long grinding time, the peak-to-valley height finally obtained no longer being within a preset limit value. The invention shortens the grinding time while at the same time improving the peak-to-valley height by a method in which a shaft surface is exposed, along a grinding line, to the action of a plane end of a grinding tool driven in rotation at high speed, the axis of rotation of which is set perpendicularly to the axis of the shaft. Advantageously, an interruption of the grinding line is achieved by a grinding tool which is centrally recessed in the manner of a cup-grinding wheel and is also composed of a fine-porous carrier material which receives a polish-grinding paste. The grinding speed of approximately 15 m/s is realised by a high-speed drive at 27000 rpm.
