Title: Process for producing a tungsten-carbide-activated electrode
Inventor: NAOUMIDIS ARISTIDES DIPL CHEM
IPC: C25B11/12
Filed: 1983-07-18
Abstract: The object is to avoid the use of expensive noble metals in a process for producing a tungsten-carbide-activated electrode with long-term stability and high electrochemical activity. The tungsten carbide is adhesively bonded to the surface of the substrate by a chemical reaction, tungsten oxide or a compound which can be thermally decomposed to form tungsten oxide being deposited on the substrate. The tungsten oxide or the tungsten compound is optionally converted into tungsten carbide by thermal decomposition and bonded to the substrate. According to the invention this is done by carburising the substrate with the tungsten oxide on it in the temperature range from 620 to 950 DEG C, preferably in a range from 750 to 950 DEG C, in a flowing CO/CO2 atmosphere.

Title: Instrument arrangement consisting of a laser transmitter, day channel and thermal-imaging channel
Inventor: WEIGEL WOLFGANG
IPC: G02B23/12
Filed: 1983-08-16
Abstract: When being assembled, the instrument arrangement (5), which consists of a laser transmitter (3), day channel (4), thermal-imaging channel (1) and observing channel (2), can be harmonized with respect to its optical axes (34, 33, 18, 33', 18') with the single collimating mark (17). The radiation (8) received and rendered visible in the thermal-imaging channel is brought together with the collimating mark with the aid of a first prism arrangement (14). From here, the radiation and collimating mark pass over a second prism arrangement, provided with a variable gap (38), of the observing channel (2) to the eyepiece (31). By contrast, when the gap is closed the radiation of the day channel (4) is directed on to the eyepiece via a second pair of rotating wedges (26) serving to adjust this radiation to the collimating mark (17). A third pair of rotating wedges (35) which adjusts the laser transmitter is synchronously co-adjusted in this connection via deviation voltages of the second pair of rotating wedges and the electrical position transducer (36). <IMAGE>

Title: Process and plant for comminuting, grinding and treating raw mineral materials, such as ores and the like, which are wet from the mine or naturally
Inventor: ZISSELMAR RAIMUND DR
IPC: B02C21/00
Filed: 1983-10-15
Abstract: In order appropriately to integrate the comminution of a bed of material, in the treatment of raw mineral materials, such as ores, fluorspar, barytes, magnesite or phosphorite, which are wet from the mine or naturally, without the raw materials having to be dried or processed with the artificial addition of water when comminuting in the wet process, an energy-saving treatment process and a corresponding treatment plant are proposed according to the invention, in which the raw materials in the naturally wet state with a water content between about 3 and 15% are subjected to a comminution of the bed of material in the gap of a roller machine (13) or roller press, the wet material, possibly agglomerates of material which have formed, leaving the roller machine being de-agglomerated in a refining device (15) such as, for example, a refining drum, and if necessary being simultaneously refined, and the de-agglomerated and refined material being supplied to a mill (24), for example a pipe mill, for grinding the material to finished-material fineness. <IMAGE>
Patent DE-3338467-A1 (DE)
Title: Rear wheel suspension
Inventor: STOTZ ERICH ING GRAD
IPC: B60G11/44
Filed: 1983-10-22
Abstract: A rear wheel suspension for vehicles with a compound suspension link axle is proposed, in which the trailing arm of each side of the axle is pivoted on a side member of the vehicle frame. The axle is supported on the body side by way of shock absorbers in the area of the axis of rotation of the wheel. Suspension of the axle is by way of leaf springs, which extend in the longitudinal direction of the vehicle close to the wheel between a cross-member of the axle and a vehicle wheel. The leaf spring is held in the trailing arm by its rear end and on the side member of the vehicle frame by its front end. Due to the absence of coil springs and their replacement by leaf springs a relatively wide boot is obtained between the wheels.

Patent DE-3343126-A1 (DE)
Title: Method and circuit arrangement for controlling an electrical drive, and an application of this method
Inventor: CORRODI ROLF
IPC: G05B19/40
Filed: 1983-11-29
Abstract: For a servocontroller having a stepping motor, the analog control voltage is converted into a pulse train (I) via a voltage-controlled oscillator. By means of a "window" circuit, which uses two threshold value transmitters to mask out a region around the zero crossover of the control voltage, rotation direction information (R) is produced and a masking-out signal is produced for blocking the oscillator. On the other hand, two signals (A, B) are produced by the pulse train (I) by frequency division, which signals (A, B) are phase-shifted through 90 DEG  and are in each case converted into two opposite-phase signals in pulse formers (TA, TB). This signal (B') leads or lags the other signal (A) in accordance with the rotation direction, by combining the lagging signal (B) with the rotation direction information (R) in an exclusive OR gate. In this way, the position information from the actuator in a stepping motor is produced without additional indicator devices, and the advantages of a stepping motor can be used in computer-aided numerical controllers. <IMAGE>

Title: Fitting for the sliding wing of windows or doors
Inventor: LAHMANN ERNST
IPC: E05D15/10
Filed: 1983-11-30
Abstract: What is provided is a fitting for sliding wings of windows and doors, which can be fastened solely to the overpiece of the window wing, so that no cutting work or the like on the wing profile is necessary in order to mount it. The lower pivoting-arm arrangements, together with their screw-on plate and the running-roller holders for the rollers running on a lower running rail, form a distortion-resistant unit, in that the two running-roller holders are connected to one another in a distortion-resistant manner, the lower end of the wing being supported on this distortion-resistant unit and thus being prevented from skewing during the opening and closing. Correspondingly, there are preferably provided for the upper part of the wing two pivoting-arm arrangements with pivoting arms which, on the one hand, are firmly articulated on the overpiece of the wing and, on the other hand, are articulated on a common rail which is itself guided displaceably on an upper guide rail of the fitting.

Title: Craft with wind drive
Inventor: VALETT JOCHEN
IPC: B63H13/00
Filed: 1984-08-16
Abstract: Wheels or marine screw propeller of a landcraft or watercraft are driven by a wind turbine via long shafts, hydraulic or mechanical transmission elements. In this case, the wind turbine is arranged such that a component of the lift produced at the turbine compensates the weight of the turbine including drive elements. Again, the point of application of the air forces acting on the turbine is located at the centre of gravity, at the lateral centre of gravity or in the vicinity of corresponding points in such a way that no, or insignificant heeling forces act on the craft, particularly in the case of watercraft. The support spar holding the turbine is connected to the chassis of the craft cardanically in order that the turbine can align itself automatically with the wind direction. During stoppage, the weight is compensated by a spring or a counterweight.

Title: Electronic ignition system for an internal combustion engine
Inventor: BAIER KARLHEINZ DIPL ING
IPC: F02P7/067
Filed: 1984-09-07
Abstract: Electronic ignition system for internal combustion engines with a family of ignition characteristic curves and a segmental disc, driven by the crank shaft, for determining the ignition timing range and the speed of the internal combustion engine, in which the segments of the segmental disc are toothed and the crank shaft speed of rotation is determined from tooth to tooth of the segmental disc. This produces a more dynamic ignition performance than with untoothed segments. A further refinement of the determination of ignition timing is achieved by determining the acceleration of the crank shaft and multiplying the speed values by this acceleration value or a value assigned to this.
