Patent DE-3737596-A1 (DE)
Inventor: BAUR FRITZ
IPC: E03F3/06
Filed: 1987-11-05
Abstract: It has hitherto been possible to effect joint sealing in concrete tubes only by pouring in the bottom region or by introducing a joint strip designed as a lip seal. In these cases, the sealing force is low, with the result that the liquid passing through the tubing may leak out in the event of relatively high pressures. By cutting open the joint to a predetermined depth and predeterminable width, the possibility is provided for fitting strand- like seals with high compression, and to do so over the entire tube circumference, thus guaranteeing perfect sealing even for a high liquid pressure.

Title: System for removing large parts from a multiple die press, optionally with a robot or lifting gear with intermediate stacking
Inventor: HARSCH ERICH
IPC: B21D43/22
Filed: 1987-11-07
Abstract: The invention relates to a system for removing large parts from a multiple die press, optionally with a robot or lifting gear with intermediate stacking. It is precisely the transporting away of the pressed parts after the last press stage which has always presented difficulties hitherto, especially when the press operates at high speed. The parts were previously deposited on to a conveyor belt, conveyed along on this and then removed manually from the belt and deposited in appropriate boxes. The aim of the present invention is to provide a corresponding automation here and is achieved by the fact that the pressed parts are optionally deposited on a deposition location in holders (several one above the other in notches) by the feed bars of the large-part press and are removed from there by means of the robot and stacked in pressed-part containers, or that the pressed parts are stacked on a lifting mechanism that can be substituted for the deposition location (Fig. 1). <IMAGE>

Patent DE-3801320-A1 (DE)
IPC: B60T7/20
Filed: 1988-01-19
Abstract: An overrun brake for trailers comprises a drum brake (3), which is equipped with an automatic reverse. The system also comprises an overrun brake (11) together with a manually operable parking brake (12). The overrun brake (11) thereby acts on the drum brake (3) by means of an overrun linkage (20). The actuating linkage (30) of the parking brake (12), which also acts on the drum brake (3), has a pre- loaded spring which compensates for the deflection distance of the brake jaws (5) of the drum brake (3) when reversing. So that the overrun brake may also be used for trailers with a pivotable drawbar (9), the actuating linkage (30) for the parking brake (12) has a lever arm (27) pivoted on the chassis (1) of the trailer, the pre-loaded spring on the lever arm (27) being arranged so that it engages between this and the drum brake (3). In this way the preloaded spring is disconnected from the vertically pivotable drawbar (9). <IMAGE>

Title: Process for the production of flexible elements from incombustible polyurethane foam
Inventor: PELZER HELMUT
IPC: C08G18/09
Filed: 1988-03-29
Abstract: The invention describes a process for the production of flexible absorption elements from incombustible polyurethane foam which are employed in the area of motor vehicle components which achieve high operating temperatures, the foaming reaction being achieved by combining two components A and B, one of which (B) comprises 4,4'-diphenylmethane diisocyanate (MDI) and the other comprises difunctional or trifunctional polyether-polyols. In order to obtain an incombustible PU foam, it is proposed that, in the production of the foam by means of suitable trimerisation catalysts, the MDI employed is trimerised in such a way that a high density is obtained in the spatial crosslinking of an isocyanurate, and the compressive hardness thereof is adjusted via the high-molecular-weight difunctional or trifunctional polyether-polyol containing corresponding crosslinking points and at least 75 to 82% of terminal hydroxyl groups (component A).
Patent DE-3816958-A1 (DE)
Title: Valve arrangement for lowering a load acting on a hydraulic cylinder
Inventor: DISTLER JOSEF
IPC: F15B11/024
Filed: 1988-05-18
Abstract: Upon the actuation of a working cylinder, a connection is made between the two cylinder spaces in order to transfer working medium displaced from the cylinder space becoming smaller into the cylinder space becoming larger. During such a lowering action, the discharge of flow medium to the tank is shut off so that the displaced flow medium can be used to fill the opposite cylinder space. Once the lowering action is complete, the retaining valve opens and the conventional mode of operation of the system is restored.

Title: Driving method for improving the overcurrent breaking performance of semiconductor circuit breakers with MOS control input
Inventor: JUNGE GUENTER DIPL ING
IPC: H03K17/687
Filed: 1989-02-21
Abstract: A driving method for improving the overcurrent breaking performance of a power semiconductor with MOS control input (power MOSFET, IGBT) is to be specified, the gate-emitter path (G-E) of which is connected to a positive control voltage (UGE) for turning on and to a negative control voltage (UGE) which can also be zero, for turning off. To prevent damage on the power semiconductor (IGBT) in the short circuit case due to excessive loading which can be caused by direct switch-over from positive to negative control voltage, without noticeable losses occurring due to this protection during the normal operation, the voltage across the gate-emitter path (G-E) is always lowered directly before each turning-off in such a manner that the power semiconductor (IGBT) does not become desaturated but a partial discharge of its input capacitance already occurs. This greatly reduces the current to be disconnected in the short circuit case so that the power semiconductor can subsequently be turned off without problems by applying a negative control voltage (UGE). <IMAGE>
Patent DE-3907003-A1 (DE)
Title: Method and device for introducing molten metal into a slab mould
Inventor: GROTHE HORST
IPC: B22D41/50
Filed: 1989-03-04
Abstract: During the introduction of molten metal into a slab mould via a submerged pouring pipe, it has hitherto been attempted, by suitable measures (deflection of the main stream) and constructional design of the submerged pouring pipe, to achieve as laminar an outflow as possible of the molten metal from the submerged pouring pipe into the slab mould in order thereby largely to avoid turbulence in the molten metal and accumulation waves on the surface of the molten metal in the slab mould, which can have a detrimental effect on the finished product, the cast and solidified metal body of the slab. According to the invention, a substantial improvement in the laminar outflow of the molten metal from the submerged pouring pipe into the slab mould is achieved by the fact that the deflected transverse stream (I, II, III, IV) is deflected by part of the vertical main stream (X) into a direction (VII-VIII) transverse to the transverse stream. <IMAGE>
