Patent DE-4229058-A1 (DE)
Title: Prodn. of wheel axle guides for rail vehicles - uses glass fibre-reinforced, unsaturated polyester resin
Inventor: HEINECKE JUERGEN DR ING
IPC: B61F5/50
Filed: 1992-08-31
Abstract: A polyester resin is applied by injection under pressure followed by a removal of tension phase. The reinforcement material is applied dry in determined sequences in a geometrically defined moulding tool, the mould is closed, and the activated resin addition is introduced into the reinforcement material pulsatingly from a pressure vessel with corresp. controlled feed by means of compressed air via pipe conduits and a moulding unit with an injection needle. When the mould is approximately 80% filled, it is vented and the covering of the glass fibres by thrust energy feed occurs as does the injection of the residual amt. of resin. USE/ADVANTAGE - To produce wheel axle guides for rail vehicles. A higher proportion of reinforcement material, i.e. greater than 50% is achieved.

Title: Grinding roll mfr. by build-up welding of anti-wear layer - with the anti-wear layer made up of separate blocks
Inventor: HABERHAUER OSWALD DIPL ING
IPC: B23K31/02
Filed: 1992-10-20
Abstract: Mfr. of a grinding roll involves application of an anti-wear layer of hard material onto an elastic carrier layer on the cylindrical roll surface by means of build-up welding. The method is characterised by the fact that the anti-wear layer is applied in the form of individual anti-wear blocks (4,4') materially separated from one another, with the separation spaces (3) between the blocks extending at least over the thickness of the hard anti-wear material. Pref., the welding process is interrupted after completion of each anti-wear block. The block produced last is cooled down. Subsequently at least the region of the roll to be provided with the next block is heated up to a required temperature. The block size is chosen dependent on predetermined maximum weld duration. USE/ADVANTAGE - Mfr. of grinding rolls for diminution of minerals, ores etc. Largely crack-free anti-wear layer of the roll is achieved by a relatively simple manufacturing process, even when the build-up welding process is interrupted.

Filed: 1992-11-07
Abstract: The electromagnetically operable double-seat valve has an electromagnet (13) which interacts with an armature (15) which is connected to a plunger (17). The plunger acts on a longitudinally cylindrical valve member (12) which is constructed as a hollow body and, on its end facing away from the electromagnet, has a collar (32) which points radially outwards and interacts with two valve seats (33,35) which are of flat construction. The one valve seat (33) is constructed on the valve housing around the slide hole (11) which accommodates the valve member (12), and the other valve seat (35) is constructed in a plate (31) which is arranged at the end of the housing hole (11). A compression spring (30) which acts on the valve member is also supported on the plate (31).In the illustrated, rest position, port (37) is connected to port (42) via a passageway (46) in the valve member (12). Energisation of the electromagnet (13) moves the valve member against the valve seat (35) and connects port (37) with a port (38,39).

Title: Radial-clearance measuring system between tunnelling shield and tubing exterior - uses three measuring sensors on shield with rays inclined rearwards and outwards to inner surfaces of shield and tubing
IPC: E21D9/00
Filed: 1992-11-07
Abstract: On the rear surface of a wall, e.g. the thrust wall (9), stiffening the casing (2) of the shield in the radial direction, are three or more distance-measuring sensors (11), fixed in position. The measuring rays (12) emanating from them are inclined against the working direction and at a known angle ( alpha ) to the shield travel axis (4). As the tunnel is driven, the distance (LS) to the internal surface of the shield casing (13) and to that of the tubing (14) are measured. From the known thickness of the tubing, the radial clearance (delta) is then calculated. USE/ADVANTAGE - The system measures the clearance between the internal surface of the rear part of the tunnelling shield and the external surface of the tubing on encountering an underground chamber. It is simple, continuous and provides accurate control of air-supply to rear of shield.

Abstract: In the case of a process for the comminution of appliances for disposal comprising hard foams or hard plastics, in particular for the emission-free recovery of fluorinated hydrocarbons from polyurethane foam insulations and other component parts, in particular of cooling units and refrigerators, the hard foams or hard plastics are comminuted together with the other parts of the appliance in a comminution device. The comminution takes place in a space which is closed off from the surroundings. The comminution device operates on the bases of the mill system, the comminution taking place interalia by a motion of the materials being ground with respect to one another, and essentially the following process steps being performed:     a) filling the comminution device with the materials to be ground;   b) rendering the interior of the comminution device inert;   c) grinding the materials to be comminuted;   d) evacuating the inert gas and gases produced during grinding;   e) discharging the comminuted materials after grinding.   <IMAGE>

Title: Metering of fuel with extra air addition for IC engine - using valve in filter tank opening to allow extra air in under certain engine operating conditions
Inventor: KROHM HARALD
IPC: F02D41/00
Filed: 1993-05-17
Abstract: The volatile fuel is fed to an IC engine from a tank with extra air via a regenerative filter. Between the filter and the manifold is the fuel pump and a valve. Between the filter and the atmosphere is another valve. An electronic control unit receives information about the engine's load condition, the state of the filter and the flow of fuel through the first valve. Accordingly, it can act to change the pump speed and valve opening. Under certain operating conditions, like cold start, it can open the second valve so that extra air is admitted to the fuel in the filter tank, at the same time regenerating the fuel filter. ADVANTAGE - Optimises engine operation with on-line fuel filter regeneration.

IPC: H01F27/40
Filed: 1993-06-01
Abstract: An ignition coil for internal combustion engines is to be designed in such a way that it can be produced with a high production reliability and has a small unit volume. The ignition coil has a spacer (21), in which a connection bolt (22) for the high-voltage connection of the ignition coil and a diode (23) connected to said bolt are held at least partially in a positively locking manner in such a way that the diode (23) and the connection bolt (22) are unidirectional in their longitudinal extents. The spacer (21) is secured on a coil former (18) of the secondary winding (17) of the ignition coil in such a way that the diode (23) is arranged above one of a plurality of chambers (29) of the secondary coil former (18) and covers at most the width of this chamber (29). The arrangement, in which the diode (23) is relieved by the spacer (21) in the event of assembly forces and in which there is no danger of voltage flashover from the secondary winding (17) for the diode (23), is used in automotive manufacture, in particular for internal combustion engines. <IMAGE>
