Title: Circuit arrangement for the conversion of bipolar analogue signals into digital signals
Inventor: LEHMANN PETER
IPC: H03M1/00
Filed: 1983-12-13
Abstract: A circuit arrangement for the conversion of bipolar analogue signals into digital signals comprises a controlled rectifier (3) and a unipolar analogue- digital (A/D) converter (1), in which each data output (7-16) of the A/D converter (1) feeds a decoder (4) feeding the measured value validity input (21) of a measured value processing unit (2) and an AND-element (5). The AND-element (5) is also fed from the data validity output (17) of the A/D converter (1), and feeds the clock pulse input (22) of a bistable trigger stage (6), the negated output (24) of which feeds its data input (25). The non-negated output of the trigger stage (6) feeds a polarity input (26) of the measured value processing unit (2) and a switching transistor (28) for controlling the rectifier (31). Thus the rectifier (31) is changed from non- inverting to inverting operation or vice versa, after each change of polarity of the analogue input, as detected from the output of the A/D converter (1). <IMAGE>

Title: Helical bending of wire
Inventor: EISINGER FRANTISEK LEOPOLD
IPC: B21D11/06
Filed: 1984-04-02
Abstract: Feed wire 10 is drawn through a plurality of staggered forming rollers 11-19 by rotation of the rollers, while the wire is also being rotated about its own axis so as to form the desired helical shaped production. The roller mechanism includes a support frame and at least four lower fixed position driven rollers 12-18 and at least five 11-19 upper idler rollers having adjustable positions relative to the lower rollers rotably mounted in the frame. The lower rollers usually have a roughened or grooved surface to facilitate drawing the feed wire through the staggered forming rollers. If desired, the feed wire can be pulled off a rotating supply reel by a pair of guiding rollers and then passed through the forming rollers to provide the desired helical shaped product. <IMAGE>

Title: Temperature sensing device with in-built calibration arrangement
Inventor: TAVENER JOHN PETER
IPC: G01K7/04
Filed: 1985-01-16
Abstract: The temperature sensing device comprises a temperature sensor, such as the welded measurement junction (10) of a thermocouple, which produces an electrical signal representative of a sensed temperature. The sensor is contained within a ceramic insulator (13, 14). A ceramic housing (15) contains the ceramic insulator and a miniature melting or freezing point cell into which the sensor, contained within the insulator, extends. The cell is closed at one end by a plug of ceramic paste (16) and at the other end by a ceramic cap (18). The cell contains a mass of material, preferably a pure metal or alloy (19), of which the melting or freezing point is known. The housing is mounted in a protection tube (22), preferably of ceramic material, having an integral closed end adjacent to the ceramic cap of the housing. The mass of material acts as a miniature version of a laboratory melting or freezing point cell so that the device can be calibrated without removing it from a temperature sensing position. <IMAGE>

Title: Radio telephone systems
Inventor: BEESLEY GRAHAM EDGAR
IPC: H04M1/72511
Filed: 1985-04-17
Abstract: In order to increase the density of use of channels in communications apparatus, especially cordless telephones, means (B,C) are provided for automatically adjusting the transmission power of each transceiver of the cordless telephone link in response to the strength and/or reliability of a signal received by at least one of the transceivers in the cordless link. Before establishing communication via a selected channel certain checks are made including - measuring the radiation strength on that channel, transmitting a signal of a predetermined duration if that strength is below a predetermined level, again measuring the radiation strength on that channel and occupying the channel if the radiation strength has not risen above a predetermined level (Box A). If the radiation strength does not rise above that level, then this is because existing users of the channel are "raising their voices" so as to be heard over the intruder. The intruder then knows not to interfere, but to seek a different channel. <IMAGE>

Title: Method and apparatus for monitoring the function of a water supply system of a mining machine
Inventor: KETTERER KLAUS
IPC: E21C35/23
Filed: 1985-12-04
Abstract: A water supply system of a mining machine is monitored by comparing the number of mechanical recoils in the entry of the cutter bits into the facing mineral with the number of the pressure surges in the water supply system. If conformity is lacking, this is converted into a signal which either leads automatically to shutting off of the machine or leaves the machine driver an only limited time to continue driving the machine. For carrying out the method here an apparatus serves in which a measuring appliance 9 is simultaneously connected for measurement with a pressure gauge 10 allocated to the water supply conduit and a vibration meter 11 allocated for example to the cutter arm, so that the recoils issuing from the individual cutter bits and pressure surges in the water system generated by the valves can be precisely retained and evaluated. <IMAGE>

Title: A method of and a device for cleaning and coating of an underwater metal surface and a shifting instrument for said kind of device
Inventor: NIINIVAARA ENSI VILJO TAPIO
IPC: B63B/
Filed: 1984-12-18
Abstract: A method of cleaning and coating of an underwater metal surface by means of a device which is pressed into contact with the metal surface and which is provided with a preferably scrabbing instrument which is displaceable with respect to said metal surface. This invention relates also to a device for cleaning and coating of an underwater metal surface, which device comprises a frame portion (1), a power unit (2) fitted in said frame portion, a driving axel (3) which is directly or by means of suitable power transmission means (4) connected to said power unit, and an instrument (5) which is pressed against the metal surface and which is displaceable essentially in parallel with the plane of the metal surface and moveable with respect thereto, which instrument is, preferably detachably, fixed on said driving axel, and to a shifting instrument for such device. The object of the invention is to facilitate and speed up cleaning and coating processes in underwater conditions and above all to provide a solution which eliminates the disadvantageous effect of water in connection with coating operations. This is achieved in accordance with the basic idea of the invention so that an electric potential difference is created betweeen the instrument (5) and the metal surface during the treating of the metal surface and so that an electrolytic coating material is applied on a heated metal surface between the instrument (5) and the metal surface, which material is thereby electrically fixed to form a permanent layer on the metal surface.

Title: Forming re-inforced tubulor structures
Inventor: ZEILINGER HANS
IPC: B29C70/56
Filed: 1986-07-28
Abstract: In order to increase the stress resistance of composite fiber structures (16) such as rotors and pressure vessels, an inherent compression stress field is established in the matrix material. This is performed by the curing of the matrix material while the fibers (12-14) are elastically stretched. In order to extend the application of this method to structures to be used at raised temperatures, fibers with a high strength and a high modulus of elasticity are employed. Carbon fibers of the intermediate type are particularly well suited. Owing to the lesser stretch of such fibers even under a high stress, the strain on the matrix material is less so that the stretch may be kept below the elongation of the matrix material, even if the material is thermally stable and is accordingly relatively brittle. <IMAGE>
