Title: Device for stacking laminated iron cores for transformers and inductor coils
Inventor: BEHR WOLFGANG DIPL ING
IPC: H01F41/02
Filed: 1987-10-21
Abstract: Stops (7, 8, 9, 11) which are adjustable in the vertical and horizontal directions are normally provided in such devices for guiding the cores, which are composed of a large number of individual laminates. Guides which have been normal until now frequently require cross-sectional changes on the iron core to be stacked or act on parts of the individual laminates which can be damaged by small mechanical stresses. According to the invention, a combination of stops (7, 8, 9, 11), composed of pulling bolts (7), rigidly guided stops (8, 9) and stops (11) supported by loose spreading elements (10) is thus provided. A device having this combination of stops is particularly suitable for stacking iron cores for large transformers having core weights up to several hundred tonnes. <IMAGE>

Title: Electrical switch
Inventor: DEL ROSSO VITTORIO DIPL ING
IPC: H01H11/00
Filed: 1987-12-31
Abstract: The invention relates to an electrical switch, especially for installation in the gearbox housing of a motor vehicle, having a contact arrangement which has at least one moving contact and is accommodated in a switching area of the housing which is bounded by an elastomer diaphragm in the form of a disc and is sealed on all sides, the contact either being operable via a spring-loaded operating plunger guided in the housing or being operable via a pressure medium, which flows into a pressure area in the housing, acting on the diaphragm. The subject matter of the invention is distinguished by the fact that the diaphragm (24) is covered by a plastic film (23) which is resistant to oil and salt water and whose thickness is considerably less than the thickness of the diaphragm (24). The plastic film expediently consists of polyester or polytetrafluoroethylene (PTFE). <IMAGE>

Title: Apparatus for continuous data exchange between driverless industrial trucks and a central control
Inventor: AUKSUTAT GUENTER DIPL ING
IPC: G05D1/02
Filed: 1988-01-06
Abstract: In an apparatus for continuous data exchange between driverless industrial trucks and a central control, in which a tuned data loop is laid along a first track, via which loop, by means of inductive coupling to coupling elements on the trucks, drive frequencies and data are transferred to truck receiver devices and/or data are transferred from truck transmitter devices, and in which a further data loop is laid along a further track, via which loop, likewise by means of inductive coupling to the coupling elements on the trucks, data are transferred to the truck receiver devices and/or data are transferred from truck transmitter devices, there being track sections in which the tuned loop is laid closely neighbouring a further loop, the tuned data loop is to be decoupled from closely neighbouring loops. This is achieved in that the further loop (S2) is severed at the place where a disturbing countercurrent is detected by a current probe (points A and B) and series loops (L, C) are then inserted here which, together with the effective inductances of the further loop (S2), yield a series resonance for the drive frequency fF. <IMAGE>

Patent DE-3802147-A1 (DE)
Inventor: HEINDL FRIEDRICH ING
IPC: B29C45/76
Filed: 1988-01-26
Abstract: For the quality control of mouldings produced by injection moulding machines or die casting machines, the individual mouldings are weighed after ejecting from the injection mould. Then, the actual weight value is compared with a set weight value and, finally, the injection moulding machine or die casting machine and/or the injection mould are influenced by a differential signal, resulting from the said comparison, by way of a weight correction for the mouldings. 
<??>In order that not only check weighings with an accuracy range of, for example, +/- 0.1 g can be carried out in the case of an injection moulding machine in operation in a production works, but also precision weighings can be accomplished under laboratory conditions in accuracy ranges of, for example, +/- 0.001 g, special precautions are taken. 
<??>Namely, on the one hand each moulding is guided as exactly as possible centrally onto the weighing zone of the check weigher and on the other hand the entire weighing zone is screened off from surrounding influences, at least during each precision weighing operation. A moulding centring channel 6 is brought out from the delivery funnel 2 of the injection moulding machine to the weighing zone 4 of the check weigher, at least temporarily, and, in addition, a shroud 7 is placed over the entire weighing zone 4, likewise at least temporarily.

Title: Etching process for patterning a multilayer metallisation
Inventor: KIM-SON NGUYEN DIPL CHEM DR
IPC: C23F1/30
Filed: 1988-02-27
Abstract: The object of the invention is to specify, for the purpose of patterning an Al-Ti-Ni-Ag metallisation system for ohmic contacts on semiconductor elements, an etching process which results in little undercutting and thus makes it possible to produce solderable, fine patterns. This object is achieved by two process versions, the first version requiring three etching processes, namely etching of the Ag and Ni layer using approximately 50% strength nitric acid, etching of the Ti layer using approximately 0.25% strength hydrofluoric acid, and etching of the aluminium layer, using a mixture of water, 85% strength phosphoric acid and 65% strength nitric acid in a mixing ratio of approximately 150:100:1. The second version requires only two etching processes, the first process being identical to that of the first version, and the second process involving etching the titanium and aluminium layer with a mixture of water, 50% strength hydrofluoric acid and 65% strength nitric acid in the mixing ratio of approximately 100:1:1. The invention can be employed, in particular, to produce a solderable contact pattern of disconnectable (interruptable) power semiconductor components.

Patent DE-3817178-A1 (DE)
Inventor: STEGMAIER ALWIN
IPC: B60T8/1761
Filed: 1988-05-20
Abstract: The proposed vehicle brake system has wheel brakes, a brake master cylinder 7, a brake force booster 8, a source 9 of auxiliary pressure and an anti-skid system. The anti-skid system comprises an auxiliary cylinder 10 between the brake force booster and the master brake cylinder, and a displaceable auxiliary piston 11 which is acted upon by pressure from the source 9 of auxiliary pressure during anti-skid operation and thereby displaces a booster piston 27 of the brake force booster towards its initial position. For the purpose of controlling the action of pressure on the auxiliary piston, 11, a first valve arrangement 12 having a pair of redundant valves 50, 51 is provided for relieving the auxiliary piston of pressure after the risk of wheel-lock has terminated. A control unit 14 associated with the first valve arrangement 12 is equipped in such a way that, before the vehicle is put into operation for example, the said control unit alternately and successively actuates the redundant valves 50, 51 into different positions. The control unit then checks whether changes in pressure, measured by means of a pressure switch 64, in the auxiliary cylinder are logically correlated with the prevailing positions of the redundant valves, 50, 51. <IMAGE>

Title: Prop stand arrangement for motorcycles
Inventor: DANICEK KAREL
IPC: B62H1/02
Filed: 1988-07-07
Abstract: A description is given of a prop stand arrangement for motorcycles which is operated via an electric motor (8). The electric motor (8) is situated within a housing (3) arranged on the frame (2) of the motorcycle, in driving connection with torque-increasing gear members (worm gear 9, gears 10a, 10b, worm toothing 11a). The driving power is borne at the end of the gear members via a worm toothing (11a) on a shaft butt (6) connected in a manner such that it is fixed on the frame. As a result, the shaft (11) with the worm toothing (11a) is pivoted together with the housing (3) via its bearings, which are not shown. Integrally formed on the housing are two supports (12a) and (12b) which support the motorcycle in the parked position. The self-locking configuration of the worm toothing (11a) makes it possible to position the motorcycle in its parked position without further locking means. The end positions of a prop stand (1) designed in this manner can be determined by a proximity switch (13). By releasing a screw connection (7) the prop stand (1) can be operated in a conventional manner using muscular power in the event of the electric motor (8) failing. <IMAGE>

Title: Apparatus for edge preparation for high-reduction rolling
Inventor: FIGGE DIETER DIPL ING
IPC: B21B13/20
Filed: 1989-02-10
Abstract: For high-reduction rolling, e.g. in a planetary mill, prior edge preparation on the slab or strand is necessary to avoid defective lateral-edge formation of the rolled strip. A wedge-shaped or convex-prismatic profile, the so-called "bursting profile" has proved to be particularly advantageous. However, owing to the formation of bulges during edging there is still the danger of defective edge formation. The object of the invention is to produce a "bursting profile" without formation of bulges by hot rolling. This object is achieved with an apparatus consisting of a vertical guide stand, a horizontal deformation stand, a vertical calibrating stand and a horizontal feed stand, which apparatus is arranged directly upstream of the high-reduction mill in the movement direction of the rolling material. The apparatus according to the invention is used in high-reduction rolling of steel and nonferrous-metal slabs or strands. <IMAGE>

Title: Hydraulic lifting unit for a lifting appliance
Inventor: OBERMEYER GUENTER
IPC: B62B3/065
Filed: 1989-04-01
Abstract: The invention relates to a hydraulic lifting unit for a lifting appliance, comprising a lifting piston, adjustably guided in a lifting cylinder and lifting or lowering a vertically adjustable chassis of the lifting appliance, and a pump piston mounted in a pump cylinder and adjustable by means of an actuating member. The pump piston draws in hydraulic medium from a reservoir during the suction stroke and feeds the hydraulic medium to the lifting cylinder during the subsequent working stroke. Provided in the lifting cylinder is a reversing member which, after a predetermined limit pressure is exceeded, causes the hydraulic medium to act on an additional cross-section of the lifting piston. A substantial reduction in the overall height of the lifting appliance is achieved according to the invention owing to the fact that the lifting piston is provided with an end recess towards the reversing member, which recess separates at the lifting piston an outer first end face and an inner, stepped, second end face, and that the reversing member is arranged in the bottom end area of the lifting cylinder in front of the first end face of the lifting cylinder, and the hydraulic medium, below the limit pressure, is fed only to the first end face or only to the second end face and, after the limit pressure is exceeded, to both the first end face and the second end face of the lifting piston.
