Title: One-pass process for making ceramic masks
Inventor: ZIMMERMANN WILLI
IPC: B22C13/08
Filed: 1982-01-18
Abstract: To make the ceramic mask, a split pattern shell mould or a mirror image of it for the hollow core of the ceramic one-pass mask, of wood, plastic or metal is required. Any combination of mould materials can be used. The shape of the mould is designed in such a way that the ceramic shell can be removed without destruction, manually or mechanically, by means of a pulling or pushing device after curing in the green condition. The ceramic outer masks and the ceramic hollow core or (solid core) are bonded together to form a boxless mould and fired. After firing, the casting material is poured into the hot boxless mould. The ceramic one-pass process for making ceramic masks is used for high-quality castings of bronze, steel or high-grade steel in general mechanical engineering.

Title: Method and measuring device for measuring the mass of a pulsating medium flowing in a flow cross-section
Inventor: GRUNER HEIKO DIPL PHYS DR
IPC: G01F15/02
Filed: 1982-08-27
Abstract: A method and a measuring device for measuring the mass of a pulsating medium flowing in a flow cross-section (1, 18) is proposed, in particular for measuring the intake air mass of internal combustion engines. The measuring device comprises, for example, a temperature-dependent precision resistor (3), whose temperature is regulated as a function of the flowing mass (2) of medium. The measurement signal (US) representing the mass of medium can be influenced as a function of the flow direction by means of a flow-direction transmitter (20, 23, 25) which has a spring member (20) which is rigidly clamped at one end and has a baffle member (23) exposed to the flow and on which there is arranged a resistance measuring bridge (25) having at least one strain gauge (26). Depending on the polarity of the detuning of the measuring bridge (25), which is a function of the flow direction, the measurement signal (US) can be suppressed via, for example, a correction stage (29) given a flow that takes place against the desired flow direction (2). <IMAGE>
Patent DE-3232395-A1 (DE)
Inventor: ZIMMERMANN HEINZ DR ING
IPC: C10G65/08
Filed: 1982-08-31
Abstract: Low-molecular weight olefins from heavy hydrocarbons are obtained with a hydrogenating pretreatment and a subsequent thermal cracking of at least a portion of the hydrogenated product. In the first stage, the polyaromatic content of a first hydrocarbon fraction high in polyaromatic compounds, e.g., a vacuum gas oil, is selectively degraded with a zeolitic hydrotreating catalyst, and in a second stage the resultant hydrocarbons are refined with a non-zeolitic hydrotreating catalyst in admixture with a second heavy hydrocarbon fraction low in polyaromatic compounds, e.g., and atmospheric gas oil. This two-stage process permits the utilization of lower operating pressures as compared to the separate treatment of the heavy hydrocarbon fractions.

Title: Internal combustion engine operated with gaseous fuel
Inventor: BERGMANN HORST
IPC: F02D19/02
Filed: 1983-01-26
Abstract: An internal combustion engine operated with gaseous fuel has a quality control and a quantity control. A gas pressure regulator for the gas supply to an air-gas mixer can be activated by a vacuum prevailing in the area of the throttle valve. A control valve acting in the quality control range of an accelerator pedal, the flow cross section of which valve is reduced as the load increases, is arranged in a control line. The ignition timing is adjusted as a function of the accelerator pedal position. In order to obtain a compact control unit which is not susceptible to faults and takes account of all operating conditions, the unit has a pressure characteristic memory to which an internal combustion engine speed and accelerator pedal position signal are fed as input variables and the output variable of which acts on a regulator which triggers a control element. An output signal of a pressure sensor and the signal of the accelerator pedal position are fed to an ignition retardation characteristic memory which with a regulator influences the ignition timing. By means of a logic control unit to which the internal combustion engine speed and accelerator pedal position signal are fed as input variables, an air-bleed valve is actuated in coasting conditions or when the internal combustion engine is over-revved.

Title: Control system for coal ploughs underground
Inventor: GARTE RUDOLF
IPC: E21C35/12
Filed: 1983-03-04
Abstract: The coal plough is guided underground on the coal-face side and is attached to the trough with upright cylinders on the goaf side, and the climbing as well as the plunging are initiated via tensile forces and cylinder pressure forces over the entire trough width. This arrangement requires high forces at the trough as well as a lot of space in the travelling track. In addition, this control system results in slow climbing. The aim of the invention is for the attached ploughs, attached on the coal side and the goaf side, in each case to lift the trough, and thus initiate the climbing and the plunging operation, by 0-80 DEG rotation of a device to both sides below the trough. The rotation of the device is initiated on the goaf side by a cylinder lying in the conveying direction. The ploughs reach directly below the trough into the floor in such a way that the trough moves with the desired height of lift on the goaf side on the one hand and on the coal-face side on the other hand. The control forces are transmitted directly to the conveyor and the plough. The cylinder is attached in a space-saving manner under the side plate.

Title: Video amplifier for connection to television pick-up tubes
Inventor: HEISTER HEINZ
IPC: H03F1/22
Filed: 1983-06-03
Abstract: To improve the signal/noise ratio of video signals at the input of video amplifiers, it is known to provide filters which raise the amplitude of video signals in the upper frequency range. Such filters are, for example, resonant circuits, several of which can be connected in series, or also multi-stage filters. The amplitude and phase response caused by the filters must be corrected in a subsequent stage. The present invention is intended for creating a video amplifier with an input filter which is simple to produce and to calibrate and the phase and amplitude response of which is easy to compensate for. According to the invention, this is achieved by means of several parallel-connected series resonant circuits (L1, L2, L3) which are tuned to different resonant frequencies in such a manner that their resonance curves intersect approximately at the 6-dB points. Each series resonant circuit is connected to an amplifier (2) and each amplifier branch contains a compensation element correcting the phase and amplitude response of the respective resonant circuit. The output signals of the amplifiers (2) are conducted to an adding circuit. The main field of application of the invention is that of video amplifiers for television cameras in X-ray technology. <IMAGE>

Title: Tab for index cards, files or the like
Inventor: OFFENWANGER WOLFGANG DIPL ING
IPC: B42F21/06
Filed: 1983-06-24
Abstract: A tab has a clamping part with an outer tab ring and an inner tab ring and an information medium, the two tab rings being resiliently splayable to form a clamping gap for securing to the edge of a sheet. The information medium is a releasable strip of paper, cardboard, plastic or the like which can be clamped between the two tab rings and has an upper transverse slit and a lower transverse slit through which the outer tab ring can be inserted toward the front side of the strip until its end, after passing through the lower transverse slit, rests on the back of the strip. The clamping part consists of a conventional paper-clip. The tab ring is particularly simple and cheap, using conventional paper-clips as the clamping part, which performs a multiple function in that it also clips together multi-sheet document sections, holds the tab against them and simultaneously clamps the strip, as part of the tab, on the clamping part. Because of its low price the strip is discarded when the tab is no longer in use.
Patent DE-3325521-A1 (DE)
Title: Reaction vessel for treating solid materials in a controlled atmosphere with the option of continuous charging
Inventor: FITZER ERICH PROF DR
IPC: D01F9/14
Filed: 1983-07-15
Abstract: The invention relates to a reaction vessel for treating solid materials in a controlled atmosphere, which has at least one port designed as a gas lock, for the purpose of charging or discharging the solid material under continuous conditions, preferably for the continuous throughput of fibre strands in the manufacture of carbon fibres. It is characterised in that the gas lock has a brush-like curtain of carbon fibres. The brush of high-modulus carbon fibres (annealing above 2000 DEG C) may press against a conveyor roller, which at the same time can be designed as a heating or cooling unit. The invention is based on the surprising effect that as a result of optimum matching of the carbon fibres to the outer shape of the conveyed solid material the mass transfer between the furnace atmosphere and the gas flow in the lock is almost completely prevented. This makes it possible to reduce the protective gas consumption to a minimum and to prevent, at the same time, the uncontrolled escape of exhaust gas. The additional effects comprise good heat distribution on the fibre strand as well as a brushing-off or spreading-out effect by the brush-like elements, and finally the prevention of electrostatic charge-up.

Title: Electromagnetic force meter
Inventor: STEPRATH WERNER ING GRAD
IPC: G01L5/13
Filed: 1983-11-26
Abstract: In an electromagnetic force meter for measuring bending stresses, a measuring cord (18) is arranged in a longitudinal hole (16) in a bolt (12). The measuring cord (18) is effectively connected to a measuring device (22) which consists of a coil (23) having an iron core (24) and a permanent magnet (25) which is connected to said iron core via a yoke (26). The bending stresses cause a length change in the measuring cord (18) and thus influence the frequency of oscillation of the measuring cord (18). In consequence, an alternating voltage is induced in the coil (23) and an electrical signal corresponding to the applied mechanical stress is produced. The force meter operates particularly easily and robustly, has little susceptibility to defects and is suitable for special applications. <IMAGE>
