Patent DE-3143878-A1 (DE)
Title: Apparatus for fixing disc rolls
Inventor: KLETZIN PETER DR ING
IPC: B21B27/02
Filed: 1981-11-05
Abstract: The invention relates to an apparatus for fixing disc rolls on floating roll shafts, in which the roll shafts are provided with tapered clamping sleeves which centre disc rolls and with clamping elements which fix the disc rolls and the clamping sleeves in the axial direction. It is the aim of the invention to achieve favourable stress distribution in the rolling bodies, to reduce the outlay on manufacture and personnel and to reduce the susceptibility of the apparatus to faults and improve the stress condition in the roll shafts. It is the object of the invention to make possible reliable and rapid fixing and removal of the disc rolls on the roll shaft without weakening the cross-section of the roll shaft by hollowing it out and to avoid the continuous presence of the hydraulic clamping device. The features of the invention consist in the fact that a prestressed spring cup is on the one hand connected in torsionally rigid but axially displaceable fashion to the roll shaft via a feather key and, on the other hand, is held axially against a disc roll by a clamping nut via prestressed spring plates. The invention can be employed for fixing machine elements on rolls.

Patent DE-3205895-A1 (DE)
Title: Self-extinguishing, non-combustible, soundproofing and heat-insulating foam mat, in particular for motor vehicles with internal-combustion engines
Inventor: SCHMALZ REINHOLD
IPC: A62C2/00
Filed: 1982-02-18
Abstract: In chemically or mechanically produced cavities of the foam mat, fire extinguishing agents (free-flowing powder or mineral fibres) are enclosed and, in the event of a fire, these agents escape at the point of the fire due to melting of the foam and stifle or extinguish or retard the flames. Before this, the fire extinguishing agents conserved in the foam provide very effective soundproofing and heat insulation. Taking into account the conditions in the engine compartment of motor vehicles, the foam mat can be fastened to the inside of the bonnet of said vehicles or laid directly over the engine and fixed by closing the bonnet. In the case of some motor vehicles, it may be necessary to protect the foam mat against contact with the exhaust routing and/or belt drives. The foam mat provided over the engine of a motor vehicle is intended to protect people against burns, deaden noises and also have the effect that, in the cold season, warming up of the engine is speeded up or made possible with little loading of the engine, as a result of which the specific fuel consumption of the engine and the harmful concentrations of exhaust gases as well as engine wear are reduced. It is advantageous if the foam mat can be removed easily and quickly from the engine compartment, in order to serve in emergencies as a fire blanket or underlay.

Patent DE-3227168-A1 (DE)
Title: Device for deforming sheets of thermoplastics
Inventor: KIEFER GUENTHER
IPC: B29C51/26
Filed: 1982-07-21
Abstract: The invention relates to a device with which sheets of thermoplastic can be fed from a stack to a conveyor, which then feeds these sheets into the mould station. The sheets are heated and deep drawn by differential pressure with the aid of a mould. A device of this type was to be improved in such a manner that the exact positioning of the individual sheets on the sheet stack and of the sheet stack with respect to the device is no longer necessary. This is especially favourable with the automatic feed of the sheet stack. This is achieved in that the sheet stack is transferred from a removal station into the feeding station by a centering device, precisely positioned thereby and transferred there to a conveyor. The invention is illustrated characteristically by Fig. 2. <IMAGE>
Patent DE-3229806-A1 (DE)
Title: Device for securing the entry and exit zone on predominantly automated mobile shops
Inventor: HEEGE BERNHARD ING GRAD
IPC: E06B11/02
Filed: 1982-08-11
Abstract: The device serves for securing the entry and exit zone of mobile shops, which can be automated by this device, that is to say it also makes self-service possible. The basic element of the device is a door which is fitted, for example, in a fence and has two mechanically coupled door leaves designed in comb form, the comb teeth of which engage in one another in the closed state and thus close the fence and, in the opened state form a barrier on both sides with respect to the mobile shop. On closing of the door, persons are forced to vacate the access area, that is to clear the danger zone. In order furthermore to ensure that no person is still in the access area when the mobile shop drives up, a sprung floor which is monitored by limit switches is arranged in the access area. The device thus intervenes in the control system of the mobile shop, so that the mobile shop cannot drive up if the door is open or if someone is standing on the floor.

Title: Method of integrating Si semiconductor components in monocrystalline Si semiconductor components
Inventor: SILBER DIETER DIPL PHYS DR
IPC: H01L21/822
Filed: 1983-03-11
Abstract: Monolithic or hybrid integration in discrete semiconductor switching elements made of monocrystalline silicon of further semiconductor components which control the switching behaviour of said elements is already known. The monolithic integration makes possible a cheaper manufacture as a result of fewer working steps and reduced space requirements per individual element; if the individual elements are formed adjacently on an Si wafer, serious connections are difficult to achieve or can only be achieved with high cost. In the case of hybrid integration, the individual components are mutually connected by metallic interconnections or by soldering-on or bonding the elements. The invention provides a method of integration which combines the advantages of monolithic integration and of hybrid technology. This is achieved by using amorphous, microcrystalline or polycrystalline silicon for the Si semiconductor component to be integrated and producing said semiconductor component by direct growth onto the semiconductor component composed of monocrystalline silicon. <IMAGE>
Patent DE-3311212-A1 (DE)
Inventor: MODSCHIEDLER KURT
IPC: H05K7/20
Filed: 1983-03-28
Abstract: The invention relates to a heat exchanger for an electronics cabinet with a folded surface profile in which, alternatingly on both faces every other fold is closed off gastight or dustproof by a cross cover. With such an air/air heat exchanger the waste heat from the interior of an electronics cabinet can be dissipated to the outside when the electronics cabinet is closed dusttight. To facilitate production of the folded surface profile, the cross covers are integrally formed onto the folds. Such a folded surface profile, in which the folds and the cross covers form one integral component, is preferably produced as a deepdrawn part, so it is possible to make the component from plastic. In another embodiment, the folded surface profile can be a plastic injection molding.
