Title: Prestressed road or runway concrete slab - has stress slabs tensioned before and after connecting initially separated sections
IPC: E01C7/16
Filed: 1980-10-18
Abstract: Sections separated by transverse expansion joints are prestressed when concrete has set, in making up roads, airfield runways or similar from prestressed concrete slabs. In each case, two or more successive sections are made with an intervening space to permit application of stressing presses, and their longitudinal stress slabs are tensioned. Prestressing force is then relaxed, and section's stress members are joined together. Spaces are filled with concrete, and stress slabs are again tensioned, from section's outer ends. Longer sections can be used, and less cross joints are involved.

Title: Ignition power supply and switching for IC engine - uses two storage capacitors discharged in parallel by two thyristors through prim. winding of induction coil
Inventor: SCHMID HANS-DIETER DR ING
IPC: F02P1/08
Filed: 1980-11-19
Abstract: In the ignition system two capacitors (10 ,11) are charged from an alternator (14) through a diode network (12,13). Alternate half cycles charge alternate capacitors. In series with each capacitor is a thyristor (18,19) with cathodes connected to one end of the induction coil's prim. winding (15a). In response to a signal from the timing circuit (20-25) both thyristors are triggered into conduction simultaneously and discharge the capacitors into the induction coil to break over the sparking plug (17). The proposed circuit utilises both positive and negative half voltage waves from the generator, and enables a higher effective energy discharge into the coil. The thyristors are positively turned off at the end of each conduction period.

Title: Transversely tilted lateral sealing rollers for support belts - of continuously travelling filter belts in slurry filter press
Inventor: LUMMERICH HANS
IPC: B30B9/24
Filed: 1980-12-08
Abstract: A filter press has upper and lower filter belts continuously circulating round small dia. rollers, and each supported for most of its filtering length on strong support belts each travelling round two large dia. rollers, all the rollers being supported in a frame. Between the filter belts is a gap sloping upwards in the direction of slurry feed and gradually tapering in depth towards the discharge end of the resulting cakes. Both support belts are braced against multiple small dia. transverse rollers at decreasing intervals as the cake forms. Some of these rollers provide area pressure and some a linear pressure. Laterally of these rollers at both sides of the press are transversely tilted sealing rollers which force together the edges of the upper and lower support belts; the sealing rollers are adjustably mounted on the press frame. For industrial slurries, e.g. from coal washing, ceramic mfg., quarrying, ore extn. The cake thickness can be increased, e.g. from 30 mm to 80-100 mm with the reliable edge seal, pressures can be raised, e.g. to 6 bar, which greatly increases output.

Title: Traffic guidance system
Inventor: HEINTZ FRIEDER DIPL ING
IPC: G08G1/0968
Filed: 1981-01-17
Abstract: A traffic guidance system is proposed which conveys information on the route to be driven to the driver of a vehicle. At fixed roadside information stations, individual information items on a particular area or a particular route, stored there in the form of the human voice, are transferred into a vehicle-internal memory (10). Naturally, the information items can also be available to the driver, for example in the form of cassettes. These information items can be called up in the correct order, that is to say in the order which determines the route to be driven, by means of a coding keyboard (13). The coding to be input into the keyboard (13) corresponds to a multiplicity of points on a road map, designated by code designations. <IMAGE>

Title: Haymaking machine for windrowing and tedding
Inventor: FRAUSCHER JOSEF
IPC: A01D78/12
Filed: 1981-05-22
Abstract: A haymaking machine for windrowing and tedding has two raking wheels mounted on a frame part which is arranged transversely relative to the direction of travel and which is itself connected to a frame extending approximately in the direction of travel. The raking wheels are rotatable about stationary raking-wheel axles supported on the ground via supporting wheels and are equipped with raking arms. The raking arms are mounted rotatably and pivotably about their longitudinal axis, can be locked in at least one position and are rigidly drive-connected to associated control rollers via control levers, the control rollers rotating in a double-track control curve leading in the direction of the raking-wheel axis. So that the diameter of the raking circle can be increased as much as possible, each raking arm is arranged, by means of a pivoting piece connected to the raking-arm bearing, so as to be pivotable about an axis which forms the generatrix of a cylinder of revolution, the axis of which coincides with the axis of the raking wheel. The raking arm can be locked in at least two pivoting positions, and the pivoting piece is articulated on the non-pivotable part of the raking wheel by means of a pivot pin. <IMAGE>

Title: Method and device for delivering the welding current to the electrode of a submerged-arc welding device for deep-gap welding
Inventor: HOCK KARL
IPC: B23K9/12
Filed: 1981-06-03
Abstract: In order to produce very deep weld seams or to weld very thick-walled workpieces (14) to one another and to be able to carry out these welds in as narrow a gap as possible, the electrode (5), which consists of a blank wire or blank strip, is guided through a kinked conduit (4) with as small an outer diameter as possible, the conduit (4) being provided on the inside with an insulating tube (9) and having in the area of the kink a contact device which is designed as a nozzle (10) and which transmits the current from the current-conveying conduit (4) to the electrode (5). The conduit (4) can be rotated about its longitudinal axis with the aid of a drive mechanism (7), so that the electrode (5) can draw the corresponding weld seams into the area of the right-hand and left-hand narrow-gap seam flank. In order to prevent a current-conveying connection between the conduit (4) and the workpiece (14), the nozzle (10) serving for the current transfer has an insulating tube (13). For adaptation to the different gap depths, the conduit (4) can be provided with an extension piece (4''). <IMAGE>
Patent DE-3125888-A1 (DE)
Title: Copper-refining installation with refining furnace and gas-cleaning device
Inventor: NIESS THEODOR ING GRAD
IPC: B01D53/77
Filed: 1981-07-01
Abstract: The invention is based on a copper-refining installation with a refining furnace, an essentially horizontally guided crude-gas duct, gas-cleaning device and clean-gas duct with a connected chimney. The refining furnace is supplied coarse copper, which is obtained with a converter, in a copper preparation. The crude gas drawn off from the refining furnace can be introduced into the chimney via the gas-cleaning device and the clean-gas duct. The gas-cleaning device consists of a sulphur-dioxide washing tower with a large number of washing nozzles for the introduction of a sulphur-dioxide washing agent and with at least one differential-pressure washing device. The washing tower has in its lower part a washing-tower sump with a sludge offtake. Arranged in front of the chimney in the clean-gas duct is an extractor blower, with which the clean gas can be extracted from the washing tower and pushed into the chimney. The refining furnace is made as a low-pressure furnace, in which a low-pressure of 5 to 20, preferably approximately 10 mm water column, can be maintained with the aid of the extractor blower. Also provided is a control circuit which has a pressure-measuring device in the low-pressure furnace and/or in the crude-gas duct. With this control circuit, the extractor blower and/or the annular-gap washing device can be controlled, via a pressure measurement, for external-air-free crude-gas extraction. Because no external extraction takes place, the sulphur dioxide can be effectively removed in the washing tower described. The sludge from the washing-tower sump can be prepared to form copper again. In the simplest case, it is introduced into the refining furnace. Soda lye, for example, is used as sulphur-dioxide washing agent. <IMAGE>

Patent DE-3146374-A1 (DE)
Title: Method and arrangement for detecting and indicating cooling malfunctions in reactor cores
Inventor: HOLICK ANTON DIPL PHYS
IPC: G21C17/00
Filed: 1981-11-23
Abstract: A method is described which is available even in the event of transient processes in the reactor, and can detect cooling malfunctions with high sensitivity. The local fuel or coolant temperature, which cannot be directly measured in a sodium-cooled fast breeder reactor is determined for this purpose from gross output, primary throughput of coolant, coolant inlet temperature and coolant outlet temperature at each fuel element with the aid of a recursive parameter and status estimating method, preferably using a Kalman filter. The determined estimated value is monitored for deviations from the desired value. Deviations initiate a fault indication. The noise of the estimated value of the local fuel temperature is substantially smaller than that of the previously employed coolant outlet temperatures, as a result of which the high sensitivity is achieved. Moreover, the simultaneous availability of the fuel and coolant temperatures improves the diagnosis of the causes of the malfunctions. Due to the continuous determination of all relevant parameters, the method is available without limiting the sensitivity even in the event of changes of state. A correction circuit also enables monitoring of short-term malfunctions of the core parameters such as occur, e.g., in the event of the passage of bubbles.
