Title: Method and device for detecting the gear position and the reduction ratio of the power train in motor vehicles
Inventor: BAUMGARTNER HANS DIPL ING
IPC: F16H59/40
Filed: 1981-10-15
Abstract: In a method and a device for determining the gear position and the reduction ratio of a power train, first and second pulse signals are generated in order to avoid a gear engagement and to achieve a simple and accurate evaluation, the pulse sequence frequencies (fM and fR) of said signals being proportional to the input-side and output-side speeds of rotation of the power train and being compared with one another electronically by forming the quotient (fM/fR) or a comparable variable. This takes place digitally by counting out and comparing a plurality of individual pulses or the pulse intervals or period of the two pulse sequences or analogously by common, weighted integration in both directions of a plurality of individual pulses of the two pulse signals. From the quotient (fM/fR) which is proportional to the reduction ratio of the power train, the respective gear position of a gearbox can be determined by comparison with predetermined threshold values. In order to determine the fuel consumption in relation to distance covered of a motor vehicle driven by an internal combustion engine, a signal which is proportional to the partial vacuum in the intake manifold is multiplied by a signal which is proportional to the calculated quotient or, in gearboxes, by a gear-dependent constant assigned to the respectively calculated gear position.
Patent DE-3141406-A1 (DE)
Title: Driving device
Inventor: MATSUHISA KOH
IPC: B65H59/36
Filed: 1981-10-19
Abstract: A carriage-driving device with cables and belts for transmitting a driving force has a spring for tensioning the cables or belts. A fixed part is arranged between the spring and the cable or belt and represents a self-locking mechanism, it being possible, if the cable or belt stretches, for the part to be moved into a position in which the stretching is taken up by the tensioning of the spring, it not being possible, however, for the part to be moved in a direction in which it is brought back into its initial position. In the self-locking mechanism, the rigid part can take the form of a disc cam segment which rests with an appropriate friction against the shaft of a rotatably held pulley around which the cable is wound, or the rigid part can engage with an appropriate friction against a swivellable part, thereby being held at a point remote from the centre of rotation of the pulley around which the cable is wound.

Title: Method for generating a correct order in the indication of the sampling channels of a logic analyser and device for carrying out the method
Inventor: HOEREN GERD HANS
IPC: G01R31/3177
Filed: 1982-03-31
Abstract: Logic analysers have groups of data acquisition sampling chips (10, 12, 14, 16) with a multiplicity of probe tips which are connected to the terminals of a product to be checked. According to the invention, the order in which the probe tips are connected can be disregarded since the correct ordering is carried out via the logic analyser (LA) itself. A permanently stored program enables the logic analyser to establish the correct order of the connections. The binary data from each group of data acquisition sampling chips (10, 12, 14, 16) are stored in a memory and can be converted into a hexadecimal form and stored in a display control device (48). A menu mode display which contains sampling channel identifiers can be displayed on the logic analyser (LA) display monitor (54) via a keypad (42). These identifiers reproduce the current order of the connections of the probe tips. A status table display of the binary (or hexadecimal) data can then be displayed on the logic analyser (LA) display monitor (54). If the probe tips have been attached to wrong terminals of the product to be checked, the keypad (42) is used for effecting the menu mode display. Using the keypad (42) and the logic analyser (LA) display monitor (54), the operator changes the order of the sampling channel identifiers on the display screen. This compensates for the incorrect order of the connections of the probe tips with the terminals. <IMAGE>

Title: Method for switching off dialling converters in telecommunication systems, particularly telephone systems
Inventor: SCHERER MANFRED ING GRAD
IPC: H04Q3/42
Filed: 1982-05-05
Abstract: The method according to the invention for switching off dialling converters in telecommunication and particularly telephone systems is based on the fact that when external connections are built up which lead to automatic announcement devices, the digit input circuit belonging to the dial converter is immediately switched off. For this purpose, all directory numbers which lead to automatic announcement devices are stored in a centrally arranged comparison memory. When it is found that such a directory number has been dialled, a switch-off instruction is immediately issued to the input circuit involved in the relevant connection.

Title: Process and equipment for processing comminuted coal by gasification by means of a multi-chamber reactor
Inventor: GARKISCH ADOLF
IPC: C10J3/84
Filed: 1982-05-08
Abstract: The process and the equipment according to the invention have the purpose of obtaining very largely phenol- and tar-free gas with a calorific value, which is not achievable according to the state of the art, of, for example, 1120-1150 kcal in a pyrolysis chamber. As Figure 1 shows, a multi-chamber reactor is used for this purpose, in the centre of which cyclone is incorporated, around which, in the interior, a combustion chamber and, on the adjacent exterior, a pyrolysis chamber are arranged. A cracking chamber surrounded by an annular flue gas chamber is provided downstream of the upper cyclone outlet. At a degree of coal conversion of 99%, a gasification efficiency of 70 to 75% is reached, the CO2 content not exceeding the norm and ignitions being reliably prevented due to the flow of inert flue gas through the coal grit and/or dust.

Title: Control device for a converter system having a controllable semiconductor actuator
Inventor: GEMMEKE KLAUS DIPL ING
IPC: B60L9/12
Filed: 1982-05-19
Abstract: In the case of this control device for a converter system which is connected to an AC voltage mains power supply and has a controllable semiconductor actuator (14), a disturbance-current regulator (27) is connected in parallel with the current regulator (25). The disturbance-current regulator is used to suppress interference frequencies (noise frequencies) which are produced by properties of the converter transformer or by the system which is connected on the DC side and interfere with operation of signalling devices. The disturbance-current regulator (27) receives (on the input side) a signal which corresponds to the mains power supply current (IF) of the actuator (14), and has a band-stop filter (28) for suppressing the mains power supply frequency component, as well as a band-pass filter (29) for selectively raising the interference frequency. The output signal from the disturbance-current regulator (27) is added to the output signal of the current regulator (25) in the sense of negative feedback. The control device is used for drives for railway vehicles and in static (solid state) AC converters. <IMAGE>

Patent DE-3227483-A1 (DE)
Title: Implantable tissue-stimulating prosthesis
Inventor: DALY CHRISTOPHER N
IPC: H04R25/00
Filed: 1982-07-20
Abstract: The invention provides an implantable tissue-stimulating prosthesis, for example a helical prosthesis, which can not only be implemented in the form of a single chip but also permits high flexibility with regard to the stimulation possibilities and the data transmission format. Only 16 electrodes are required for stimulation of 15 different sites. Every site is stimulated by a two-phase impulse under the control of two adjacent electrodes, the polarities of which are reversed in the middle of each stimulation phase. Although transmission requires a pulse-width modulation format, the exact shape of the format can be varied in order to reach greatly different possibilities of stimulation. For example, a single site can be stimulated during each transmission frame or several sites can be stimulated during the same frame. Although only one site can be stimulated at any arbitrary point in time the system nevertheless works so rapidly that stimulations are perceived simultaneously. The system is designed for minimum consumption of energy and operation is reliable in that no site can be stimulated for longer than a predetermined time interval.

Title: Method and apparatus for the production of rolled strip with a high strip-profile and strip-flatness quality
Inventor: KLOECKNER JUERGEN DR
IPC: B21B37/28
Filed: 1983-03-14
Abstract: In a method and an apparatus for the production of rolled strip 7 with a high strip-profile and strip-flatness quality, the rolled strip 7 is passed successively through a tandem hot-strip mill and a tandem cold-strip mill. During the strip-rolling operation, it is subjected to condition control comprising strip-profile control at least in one rolling stand and, if required, control of strip flatness in at least one further rolling stand. In the tandem hot-strip mill only strip-profile control is performed up to a "critical thickness" of the hot strip 7 of about 12 mm (rolling stand 1 to 3). When the strip 7 has undershot the "critical thickness" of about 12 mm, only control of strip flatness 10', 15', 11; 16; 12, 17 is performed in the tandem hot-strip mill (rolling stand 4 and 5) or in the tandem cold-strip mill. <IMAGE>

Title: Thermodynamic process system
Inventor: KRANIGK HELMUT
IPC: F25B15/14
Filed: 1983-03-19
Abstract: The invention relates to a thermodynamic process system in which the evaporated sorptive is adsorbed by a porous adsorbent and the sorptive compressed in the pores of this material is electroosmotically conveyed by means of two porous electrodes. In known systems of this kind for the production of cold, the efficiency is low compared with compressor-operated refrigerators. The electroosmotic forces do not act from the beginning on molecules of sorptive which primarily adhere in the pore mouths or a surface layer of an adsorbent. A suction pressure is produced whose effectiveness, with narrow-pore media, is already low in adsorption rate and throughput rate, for reasons of friction. A thermodynamic process system is provided by the invention, by which a continuous, optimisable and controllable, and also sufficient, mass flow of an employed sorptive is achieved, by the surface of the adsorption material (5) on the adsorption side (11) being in contact with a porous electrode (6'), and this electrode, and also the adsorption- side region of the pore mouths of the adsorption material (5), being cooled. <IMAGE>

Title: Spindle lifting or sliding gear
Inventor: KAROLI WERNER DIPL ING
IPC: F16H57/027
Filed: 1983-06-16
Abstract: The invention comprises the improvement of a spindle lifting or sliding gear with grease-lubricated working spindle 4 and oil-lubricated worm transmission 2/3, which, on account of its modular construction, serves, in a wide range of installation positions, e.g. as an adjusting or positioning gear for machine tools, experimental arrangements, airport equipment, railway maintenance installations, theatre stage installations, etc. Despite decades of development of such gears it has scarcely been attempted hitherto to improve the notoriously poor efficiency of such gears, which would be desirable especially with regard to motor drive. In the spindle gear according to the invention, an approximately twofold increase in efficiency is achieved by design measures which are based on the knowledge that the lubricating effect of lubricants improves the less it is heated, i.e. the development of frictional heat is avoided and provision is made to dissipate the same from the gear. This is achieved according to the invention by a gearbox construction in which the meshing area of drive worm/worm wheel 2/3 in each gear installation position lies entirely in the oil bath, and furthermore the meshing area of spindle nut/working spindle 3/4 is constantly lubricated from a grease chamber 3c of the spindle nut 3, the gearbox 1 having cooling ribs 1k in the worm area, and furthermore the worm wheel 3 ... radially in ...

Title: Method and apparatus for continuously measuring the viscosity of non-Newtonian media
Inventor: KUEHN ULRICH DIPL ING
IPC: G01N11/14
Filed: 1983-07-23
Abstract: A method and an apparatus for continuously measuring the viscosity of non-Newtonian media, in particular chocolate mixture, can be used in process measurement, inter alia, in liquid rubber processing, in lacquer and paint production, and in the confectionary industry. The object of the invention is to provide a method and an apparatus which functions more precisely than the solutions which have been disclosed, and which eliminates the process-engineering and equipment-engineering deficiencies of known solutions and makes possible process control and regulation. The object is achieved in that the test material is drawn off from a pipeline with the aid of a pump and is pumped into the two-chamber measuring cell which has a free discharge. Situated on the two-chamber measuring cell are two modified rotating viscometers employing different rotary speeds. The difference is to be taken between two temperature-compensated voltage signals. Said differential signal is fed to an analog display calibrated in Pa . s against a laboratory viscometer or to an A/D convertor.
