Title: Casting mould for the production of castings
Inventor: RUEGER HANS
IPC: B22D15/04
Filed: 1992-11-17
Abstract: The invention relates to a casting mould for the production of castings, comprising a frame (28) with, mounted on it, a permanent mould (1a, 1b) which is split lengthwise and surrounds a mould cavity, the parts (2, 3) of the permanent mould being movable in the transverse direction by means of pressure-operated mechanisms for the purpose of opening and closure. At one end, the casting mould has a gate (97) for the supply of the metal melt. The casting mould furthermore contains a number of core blocks (6, 7, 8) assigned to the permanent mould (1a, 1b). At one end, the permanent mould (1a, 1b) is equipped with a distributor block (94) for the metal melt, the gate (97) being routed via the distributor block (94) in such a way that the metal melt is split up and fed to separate runners (9) in a lower core block (6). This makes possible particularly rapid and uniform inflow and optimum distribution of the metal melt, making it possible to cast large and complex castings such as the engine blocks of internal combustion engines satisfactorily by gravity casting (Fig. 5). <IMAGE>

Title: A device for reducing longitudinal accelerations in motor vehicles for the driveline
Inventor: LOTH STEFAN
IPC: F16F15/16
Filed: 1993-03-03
Abstract: A reduction of the comfort-reducing vehicle longitudinal accelerations (bucking) due to oscillations in the driveline of motor vehicles can be achieved by means of a device with damping characteristic, without incurring the said disadvantages of known measures. The device comprises one or more chambers, filled with a hydraulic or other liquid/fluid, which are connected to one another by one or more valves. The valves are adjusted so that they open, resulting in slip, only at a certain pressure, for example in the event of torque peaks in the driveline. As a result, bucking oscillations are damped. It is possible to fit the device in existing design elements, for example into the flywheel.

Title: Nuclear magnetic resonance device having at least two transmit frequencies
Inventor: KOLEM HEINRICH DR RER NAT
IPC: G01R33/62
Filed: 1993-08-03
Abstract: In the case of a nuclear magnetic resonance device for examining first atomic nucleus species which have nuclear-magnetic coupling with second atomic nucleus species, signals at the resonant frequency of the second atomic nucleus species are additionally injected in order to improve the spectral resolution and/or the signal-to-noise ratio when examining the first atomic nucleus species.

Title: Method for measuring the filling level of a liquid in a container, using the radar principle
Inventor: POL RONALD VAN DER
IPC: G01S13/10
Filed: 1993-08-15
Abstract: A method for measuring the filling level of a liquid in a container, using the radar principle, in which a microwave signal is emitted in the direction of the liquid level from an antenna (transmitting antenna) arranged above the liquid level, in which a measured signal reflected at the liquid level is received by the antenna (transmitting antenna) or preferably by a further antenna (receiving antenna) and in which the filling level is calculated from the propagation time determined for the measuring signal, leads to an improvement in the reliability of the measurement method as a result of the fact that interfering signals occurring in a measured spectrum and independent of the filling level of the liquid are corrected with the aid of the measured intensity of a first interference signal. <IMAGE>

Title: Process for the disposal of paint sludge from coating plants
Inventor: VOIGT BODO DIPL ING
IPC: C21B5/00
Filed: 1993-08-21
Abstract: The invention relates to a process for the disposal of paint sludge from coating plants, which sludge arises through the interception and washing-out of paint mist from spray booths in and/or with water, followed by sedimentation. In the process, the paint sludge removed is coagulated by admixing to it very fine inorganic particles having a large adsorbing surface area as detackifying agents, preferably of alumosilicate. The coagulated paint sludge is dried in a plurality of stages to give flowable granules. In order to dispose of the coagulated paint, these granules are introduced by way of the tuyères of a blast furnace, together with the blasting air, into the crude iron extraction process of a blast furnace, the organic constituents of the coagulated paint being used as part of the reducing agents and the inorganic constituents being used as part of the slag-forming material. The paint sludge contains about 30% by weight, based on the dry mass of the coagulated paint, of inorganic detackifying agents. Prior to being blown into the blast furnace, the coagulated paint is ground to a particle size not more than 1.0 mm, and predominantly about 0.2 mm, and dried to a residual moisture content which is preferably no more than 5%.

Patent DE-4445779-A1 (DE)
Inventor: ESCH THOMAS PROF DR ING
IPC: F01N3/20
Filed: 1994-12-21
Abstract: A process is disclosed for controlling a multiple cylinder internal combustion engine in which exhaust gases undergo subsequent treatment. To ensure a gaseous exchange, at least air is supplied to the individual cylinders through inlet devices and exhaust gases are discharged through outlet devices. Inlet and outlet devices are independently driven but their opening and closing times may be synchronised. Beginning in the cold start phase until the warming up phase, fuel is supplied to only part of the cylinders that act as an engine and the supply of fuel to the other cylinders is cut off. The other cylinders work then as compressors. The air volume heated in these cylinders by compression flows through the outlet device into the exhaust gas system and reacts with the exhaust gases.
