Title: Cooling box for steel-making arc furnace - has slag lodging portion with curved end portions to prevent cracking and inhibit stress concn.
Inventor: UDOH EIJI
IPC: F28D1/06
Filed: 1980-12-19
Abstract: A cooling box for installation in the refractory wall of a steel-making arc furnace comprises a base plate having inlet and outlet pipes for coolant. A heat-receiving Cu plate has an integral slag lodging portion formed with alternate furrows and projections and curved peripheral end portions. A back plate defines a coolant chamber with the heat-receiving plate. Horizontal partitions divide the chamber into a zig-zag flow pattern which is narrow and flat over the width of the heat-receiving plate. The curved end portions of the heat-receiving plate serve to eliminate or inhibit stress concn. and cracking. This is useful in eliminating leakage of cooling medium and associated explosions that can occur at hot spots and adjacent the slag line.

Title: Filter candles for chemical investigations and for measurements in COD determination
Inventor: JUNG WILLI DIPL CHEM DR
IPC: B01D39/16
Filed: 1981-01-20
Abstract: In this invention as a patent of addition to the European patent number 80104421.5, especially selected granular raw materials based on metal and/or plastic and/or glass and/or naturally porous material are used alone or in a mixture, in place of the special glass. Depending on the application, one or other of the materials can be better suited as candle raw material. It is only important to select the mixture so that after the sinter moulding process the desired pore size of the filter candle is given. Whereas in virtually all usual cases, especially in COD determination, use is made of the glass filter candle which is described in the main patent and is preferably made of ROBU glass, the production of the candles described here is substantially reserved for special cases. The equipment remains virtually unchanged.

Title: Monitoring device for detecting fault arcs in encapsulated, gas-insulated switching installations
Inventor: BAYER HELMUT
IPC: H02B13/065
Filed: 1981-03-19
Abstract: A semi-reflecting window (3) is located in the wall (2) of a gas-insulated, encapsulated switching installation. Ending on its outside is an optical fibre cable (5). Located behind this is an optical filter (6). Located in one beam path (7) of the filter (6) is an evaluation device (8) having an amplifier (9) downstream from which there is arranged a device (10), which contains a timer, for detecting earth shorts, and a tripping element (11). The evaluation device (6) with the amplifier (9) is connected to a circuit arrangement (12a) of a generator (12). With a transmitter (13), said generator (12) forms a light-pulse unit. Periodic pulses from the transmitter (13) pass to the optical filter (6), to the window (3) and to the evaluation unit (8) as well as, converted into electrical return signals, to the circuit arrangement (12a). The latter emits a defect indication if the return signals are absent. The light from a fault arc passes from the window (3) through the optical fibre cable (5) to the evaluation device (8). An interference signal is produced here which energises the tripping element (11) when there is at the same time an earth short on the device (10) and the time set in the timer has been exceeded. <IMAGE>
Patent DE-3113914-A1 (DE)
Title: Air duct, in particular air exhaust duct for the interior of a motor vehicle
Inventor: BRUHNKE ULRICH DIPL ING
IPC: B60H1/24
Filed: 1981-04-07
Abstract: In the case of air ducts and in particular air exhaust ducts in the rear columns of motor cars, space is often very restricted, so that complicated deflections in a narrow space are frequently necessary, which is often made more difficult by projecting corners or edges. However, an inner surface which is as smooth as possible and a cross-sectional area which is as constant as possible are sought in this respect. To achieve this, the invention proposes lining the interior of the duct with a tubular covering which is flexible in the installed state, after installation can be brought to its final position with the introduction of superatmospheric pressure into the duct and is fixed in this position.

Patent DE-3118859-A1 (DE)
Title: Infeed device for a tooth-flank grinding machine
Inventor: EIK KURT
IPC: B23F23/12
Filed: 1981-05-13
Abstract: The invention relates to an infeed device for a tooth-flank grinding machine, at which the tangential allocation of the grinding body to the tooth flank is effected by an axial displacement of the threaded spindle or spindle nut serving to produce the rolling movement. The axial displacement travel is set by adjustable stops, the adjusting travel of which is limited by fixed end stops. The aim is to ensure that the stops, when being shifted into the extreme positions, do not touch one another or the fixed end stops, since otherwise the infeed gearing can lock in particular during motor-operated adjustment of the stops, which leads to downtime of the machine. One electrical displacement-voltage transducer each is allocated to the adjustable stops, and an adjustable voltage divider is allocated to the fixed end stops. When a certain difference in voltage is reached between the two displacement-voltage transducers and when the voltage at the displacement-voltage transducer coincides with that at the adjustable voltage divider, the adjusting drive is switched off. Variable resistors are conveniently used as the displacement-voltage transducers, and one slip clutch each is connected upstream of the variable resistors in order to facilitate the adjustment. <IMAGE>

Title: Method for producing a film resistor
Inventor: BREM WALTER DR ING
IPC: H01C17/242
Filed: 1981-05-21
Abstract: A method for producing a film resistor as a measurement resistor for resistance thermometers, in which a thin resistor film (2) of platinum is deposited on a main surface of an electrically insulating supporting body (1), in the form of a small plate, by cathode sputtering, the electrical resistance of which resistor layer is a measure of the temperature, the resistor layer (2) for achieving the required temperature co-efficient being subjected to an annealing and subsequently being structured by means of a laser beam into the form of a meandering track. In this case, a meandering partial resistor (R1) is cut into the resistor layer (2), the resistance of which partial resistor is less than the desired resistance of the measurement resistor. After temperature treatment of this partial resistor (R1), series resistors are cut into the resistor film (2), the partial resistor (R1) being used for determining the temperature of the resistance film (2) and the meandering structure of the resistor film (2) being interrupted when the resistance (RN) measured simultaneously between the connecting surfaces (21) of the measurement resistor corresponds to the desired resistance (RN,O) determined by a computer at normal temperature. <IMAGE>

Title: Procedure for the synchronous control and differential-angle setting of at least two propeller shafts
Inventor: KRANERT KLAUS DR ING
IPC: H02J3/40
Filed: 1981-11-07
Abstract: The application deals with a procedure for the synchronous control of at least two propeller shafts with synchronous shaft generators, a parallel circuit of an electronic power switch and an inductance being arranged between shaft generator and ship's supply system. Slipping of one shaft generator and synchronising at the zero voltage is made possible by switching on the inductance. To control the shafts, a difference is formed from the actual values of power and current or from the load angles of the shaft generators and is fed forward as a disturbance variable. During the slip action of one of the shaft generators, the feedforwarding of the disturbance variable is interrupted via the associated power switch. The slip action at certain ship points is carried out until the propeller shaft has rotated relative to the other propeller shaft by one blade division. Further slipping is counted and the optical blade position is determined and firmly set. <IMAGE>
