Title: Tool for deforming structural components by means of a fluid acting inside a blank
Inventor: TOMASEK JIRI DIPL ING
IPC: B21D26/02
Filed: 1982-12-09
Abstract: The invention relates to a tool for deforming structural components by means of a fluid acting inside a blank, the said tool comprising two deformation mandrels, at least one of which is provided with an opening for the supply of the working fluid. The purpose of the invention is to reduce the high consumption of deformation fluid, to increase the capacity of the machine and to eliminate the risk of the formation of internal waves and folds in the deformed element. The invention consists essentially in that a functional component is arranged on each deformation mandrel, in that its diameter is smaller or at most equal to the inside diameter of the deformed structural component, in that its diameter tapers towards the end of the deformation mandrel and its length is at most half the length of the deformed structural component after the end of deformation or in that the functional component of the deformation mandrel simultaneously forms a gauge of the inner shape of the deformation of the deformed structural component.

Title: Independent wheel suspension for driven motor vehicle wheels, especially steered front wheels
Inventor: BRAUN RAINER
IPC: B60G11/14
Filed: 1983-01-26
Abstract: In the case of an independent wheel suspension for driven motor vehicle wheels, the wheel carrier of which, held on a shock absorber strut, is guided by a control arm arranged below a drive shaft and pivoted on the vehicle body, a spring element, for example a helical or pneumatic spring, is provided between the shock absorber strut and the body-side joint of the control arm, viewed in the vehicle's longitudinal direction. This spring element is arranged above the drive shaft and is supported at the top on the vehicle body and at the bottom by way of a support element on the control arm gripping the drive shaft on one or both sides. Neither the wheel carrier nor the outer tube of the shock absorber strut is therefore employed in supporting the spring element at the bottom. Consequently the spring element remains unaffected by steering movements and creates space at the side of the wheel which is of advantage, for example, for the fitting of a snow chain.
Patent DE-3308757-A1 (DE)
Title: Apparatus for the production of boxless moulds
Inventor: ACHINGER MICHAEL
IPC: B22C11/10
Filed: 1983-03-11
Abstract: In an apparatus for the production of boxless moulds, especially horizontally or vertically parted sand moulds, with a machine frame (1) having mould boxes and a model plate carrier (7) which is constructed as a hollow box with suction openings, which can travel into or out of the machine frame, and which is mounted by means of a suction-conducting support pipe (10) or the like on a reduced pressure container (11) having a suction connection (12), the support pipe (10) is non-displaceable in its longitudinal direction (A) and is connected, sealed from the atmosphere, to the reduced pressure container (11). The reduced pressure container (11) is displaceably arranged for the inward and outward travel of the model plate carrier (7). A better efficiency of the mould machine during shoot moulding results from a more favourable design of the flow paths for the suction air and a better sealing between the support pipe (10) and the reduced pressure container (11). Oil contamination of the mould sand particles entrained by the suction air is prevented by dispensing with oiled slide bearings between the support pipe (10) and the reduced pressure container (11). <IMAGE>

Patent DE-3320866-A1 (DE)
Title: Stretcher
Inventor: SCHUMANN ERWIN
IPC: A61G1/017
Filed: 1983-06-09
Abstract: Stretchers generally comprise longitudinal bars on either side, a piece of fabric arranged between these bars and transverse beams which keep the bars at a distance from one another. Besides these, there are also portable chairs or invalid chairs. Before a rescue operation it is often impossible to decide whether it would be more expedient to use a flat stretcher or a portable chair because this depends on a variety of factors, for example on the type and severity of the injury of the individual to be rescued, on the terrain, on the length of the transportation route and the like. Therefore, in order to provide a stretcher which combines the advantages of a normal stretcher with those of a carrying chair, so that the individual to be transported can be conveyed, as desired, in a lying or sitting position, it is proposed that the bars be designed so as to be slideable into one another in the manner of a telescope approximately from their central region to the foot end of the stretcher, that an articulated linkage be provided on the telescopic bar parts in such a way that the linkage forms a carrier seat from the essentially flat stretcher with the part of the piece of fabric fastened thereon, when the telescopic bar parts are pushed into one another.

Title: Sales animator
Inventor: RECKWITZ PETER J
IPC: G09F19/00
Filed: 1983-10-08
Abstract: In order to record and reproduce advertising information with the aim of referring prospective customers to articles, in particular with the aim of awaking interest to buy, a device is used whose frame is constructed to stand out and which is fitted with lamps arranged with a spacing. These lamps are connected to a current source via an electronic circuit so as to circulate in a prescribed sequence and in a prescribed cycle, resulting in a type of luminous strip. The advertising carrier arranged at the centre is highlighted by this intense luminous strip in such a way that the advertising at which it aims is intensified. Since such devices with an electronic circuit operate in a milliampere range, not only is the promotional effect enhanced, but at the same time a cutting of costs is also achieved by comparison with spots customary to date. <IMAGE>

Title: Control for the distribution points of marshalling hump track systems with a central automatic control
Inventor: ENNULAT DIETRICH DIPL ING
IPC: B61L17/00
Filed: 1984-03-15
Abstract: The reports originating from the run-in and run-out contacts (E1 to E3, A11 to A32), of the distribution points (W1 to W3) of a marshalling hump track system are stored in separate memories (FIFO 1, FIFO 2). The reports originating from the run-in contacts are treated with priority status in a processing device (VE). For this purpose, an evaluation logic (AL) tests before each input of a report originating from a run-out contact whether the run-in contact reports are present and then feeds these reports to the processing device (VE) via switches (U). The priority treatment of the reports originating from run-in contacts is provided because the processing of a queue could delay the treatment of these reports and possibly lead to operations and persons being put at risk. <IMAGE>

Title: Contact system for a high-voltage interruptor switch
Inventor: FRIEBE HARRY
IPC: H01H31/36
Filed: 1984-03-30
Abstract: In the case of a contact system for high-voltage interruptor switches, especially gripper interruptor switches, a main contact piece (3) (shears) interacts with a mating contact piece (2). A pre-contacting device (14) can be connected in parallel with these two contact pieces (2, 3), which pre-contacting device (14) is arranged on the mating contact piece (2), can be operated by the main contact piece (3) and is intended for guiding an arc. The pre-contacting device (14) opens after the two contact pieces (2, 3) have opened and closes before they close. In this case, a part (14c) of the pre-contacting device (14) is supported by the mating contact piece (2) in an electrically insulated manner. In the switched-off position, a further contacting device can be connected in parallel with the pre-contacting device (14), which further contacting device forces potential equalisation. In order to simplify the contact system and in order to avoid high-resistance equalisation resistors, the potential equalisation contact device is formed by the mating contact piece (2) and the moving switching pieces (14c) of the pre-contacting device, the main contact piece (3) being isolated in DC terms from the mating switching piece (2) and its pre-contacting device (14) when the potential equalisation contact device is closed by a solid insulating means (21) which is provided in addition to the existing gaseous insulating material. <IMAGE>

Title: Brake system for heavy road vehicles
Inventor: KAHRS MANFRED DR ING
IPC: B60T1/087
Filed: 1984-11-02
Abstract: In a brake system for heavy road vehicles a foot-operatable service brake (18) and a manually operatable friction brake (1) is provided as parking brake. The friction elements of the friction brake can be operated by way of a manually operatable control valve (6) with slide and an operating element (2) connected to the control valve (6) on the output side. In order not to cause overheating of the service brake on longer downhill runs, it is designed as a hydrodynamic hydraulic retarder (18) easily cooled by the vehicle cooling system, which retarder is effective over the entire speed range of the vehicle. The slide of the control valve (6) can be adjusted so as to activate the friction brake (1) as a function of the difference between a reference value and an actual value of the brake pressure of the service brake (18), determined by a comparator device (11) only when the reference value exceeds the actual value by a predetermined amount. The friction brake is therefore automatically switched on only in the event of a complete or partial failure of the hydraulic retarder, so that it acts as emergency brake. In addition it can also be manually operated as a parking brake. <IMAGE>
