Patent DE-3133625-A1 (DE)
Title: Current collector for high-speed railways
Inventor: BUCKSCH ROLAND DIPL PHYS
IPC: B60L5/22
Filed: 1981-08-21
Abstract: The invention relates to a current collector for high-speed railways with vibration behaviour which is reaction-free with respect to rocker and frame and absorbs a large part of the energy of the waves impinging on it. The invention consists in the fact that given reduced masses of the rocker (m2) and of the frame (m1) and given a predetermined voltage (S) and mass assignment ( mu ) of the contact wires, the damping constant d1 of the frame and d2 of the rocker are as follows     1) d1 = d2 = 2 <IMAGE>  and the spring constant of the rocker spring   2) f = d1<2>/m1 the mass assignment being the quotient of mass and length. The current collector according to the invention does not have any resonant frequencies and can therefore not be excited to experience undesired neutral frequencies by the vibrations of the locomotive roof. It behaves with respect to the oscillations of the contact wire like an unsprung but damped mass which reacts quickly to the waves in the contact wire without troublesome vibrations. <IMAGE>

Title: Moment-limiting arrangement for cranes with articulated jibs, in particular those which are provided for mounting on trucks
Inventor: FERRARI GIANNI
IPC: B66C23/90
Filed: 1981-11-19
Abstract: This moment-limiting arrangement contains an appliance which is able to detect instant by instant the moment to which the crane is subjected as well as an appropriately adjusted control device which is able to compare the moment to which the crane is actually subjected with a reference limit value and, as soon as the actual moment reaches the said limit value, is able to trigger the opening of a drain valve which directs to the drain the fluid quantity discharged by the pump and fed by the distributors to the hydraulic winches which control the jibs of the crane. In addition, means are provided which, in the event of the maximum permissible moment value being reached, act on the said drain valve and on the distributors of the various winches so that then only the winch movements can be performed which as an overall action bring about a weakening in the moment to which the crane is actually subjected.

Title: Planar process for producing a transistor in a monolithic integrated I<2>L circuit
Inventor: HERRMANN HANS DIPL ING
IPC: H01L21/8226
Filed: 1982-02-16
Abstract: In a planar diffusion process for producing a transistor in a monolithic integrated I<2>L circuit, the transistor has at least one collector zone at the surface of a semiconductor body and one emitter zone which comprises a heavily doped interlayer at the interface between a substrate of one conduction type and an epitaxial layer of the opposite conduction type into which an injector zone of the first conduction type is inserted. A heavily doped subzone of the same conduction type as the heavily doped interlayer is driven into the epitaxial layer in such a way that, after the base zone and the collector zones have been driven in, their front is penetrated from the surface to a distance between the distance of the emitter-base p-n junction and the distance of the surface of the heavily doped interlayer facing the latter. <IMAGE>

Patent DE-3215874-A1 (DE)
Title: Process for operating ion exchanger beds which replace multivalent ions present in dilute solution with monovalent ions
Inventor: VAJNA SANDOR DIPL ING CHEM DR
IPC: B01J49/00
Filed: 1982-04-29
Abstract: Dilute solutions to be evaporated often contain multivalent ions in the solution which form sparingly soluble salts with oppositely charged ions when the concentration of the solution during evaporation has exceeded the saturation limit. The multivalent ions are therefore in most cases removed from the solution by exchange with monovalent ions using ion exchange (loading). In many cases, the concentrate from evaporation can be used to regenerate the used ion exchanger. Loading, evaporation and regeneration are repeated successively many times in a cyclic sequence. Accumulation of the multivalent ions on the exchanger bed and in the treated solution then occurs. The concentrate is often not completely used up in regeneration. The residue is, according to the invention, stored and used as regeneration solution; if the volume of such a residue is insufficient, several of them are combined. This slows the accumulation down. However, when it is necessary to interrupt the cyclic sequence, a solution is used for regeneration which contains only the salt, introduced from outside, of the monovalent ion. The residues of the concentrate, arising from the first cycles of the cyclic sequence, can also be used for the same purpose.
Patent DE-3220866-A1 (DE)
Inventor: HUBER HANS DR
IPC: C08G18/10
Filed: 1982-06-03
Abstract: The present invention relates to resin mixtures which are fluid at temperatures up to 100 DEG  C. and which crosslink either at elevated temperature or under the influence of moisture. Thermal crosslinking takes place at temperatures of 100 DEG  C. and up, preferably at about 120 DEG  C. The mixtures contain one or more mutually compatible polymers containing hydroxyl groups, in which at least 5% and not more than 90% of the hydroxyl groups are replaced by alkoxysilyl groups. The introduction of the alkoxysilyl groups is accomplished by the reaction of a diisocyanate with a hydroxyl group on the polymer, on the one hand, and with an aminosilane or mercaptosilane ester on the other. On the basis of their fluid-to-viscous consistency at room temperature or moderately elevated temperature, the resins can be applied in a thin coating and easily crosslinked in situ.

Patent DE-3224548-A1 (DE)
Title: Electrical tool with a universal motor
Inventor: WOLF OTTO DIPL ING DR
IPC: H02P23/24
Filed: 1982-07-01
Abstract: An electrical tool with a universal motor, whose rotation direction can be reversed by means of a changeover switch from clockwise running to anticlockwise running and vice versa, clockwise running of the drive always being ensured after the changeover of the drive when the electrical tool is brought back into use, irrespective of the previous operating rotation direction, is intended to be improved to the effect that a changeover to anticlockwise running during full, correct clockwise running is prevented and, furthermore, an inadvertent changeover to anticlockwise running is prevented. This is achieved according to the invention in that the switching contactor contains at least one additional switch contact which simultaneously causes electrical isolation of the drive motor from the supplying network when the push-button switch is operated for the purpose of changing over the drive motor from clockwise running to anticlockwise running, and in that this isolation can be rectified again by a switching process that takes place at a time which can be selected, when the rotation direction changeover switch is in the anticlockwise running position.

Filed: 1982-08-06
Abstract: The invention relates to a handle for a burner for liquid or gaseous fuel, with a control member which controls the fuel feed, controlling a fuel control valve arranged in the handle and being manually adjustable by the user. A handle construction is proposed by the invention which optimally corresponds to the practical requirements, i.e. simple manipulation of the burner, in that the control member (16) is formed by an annular-cylindrical part which is arranged on the burner end of the handle, is axially displaceable towards the burner against a spring loading, and is indirectly connected to a spindle (14) which controls the supply of fuel to the burner. <IMAGE>
Patent DE-3231493-A1 (DE)
Title: Pressure-tight internal closure of tube sections during reduction of the cross-section by forming
Inventor: MUELLER BERNHARD DR ING
IPC: B21D41/04
Filed: 1982-08-25
Abstract: Tubes are often reduced in cross-section - generally at the end - in such a way that there is no residual internal space at that point. Common to all the forming methods is that, however great the reduction of the external cross-section, there is still a small residual space. This may be so small that it is invisible. This axial residual space is sufficient for gases or liquids in the interior of the tube to escape via this residual space. In order to prevent this, a material, the melting point of which is lower than the relatively high temperature, arising during deformation, of the tube to be formed, is, according to the invention, introduced into the tube section to be deformed immediately prior to forming. This section of material melts when touched by the tube during forming and remains in the liquid state in the residual space. After forming, the material solidifies and forms the pressure-tight closure.
Patent DE-3231896-A1 (DE)
Title: Summerhouse
IPC: E04H1/12
Filed: 1982-08-27
Abstract: The invention relates to a summerhouse, the vertical walls of which are formed by a plurality of wall parts interconnected in each case at a preset angle. A summerhouse of this type is to be constructed so that summerhouses of any desired different cross-sectional shapes can be assembled, with the shape of the wall parts remaining the same. This can be achieved according to the invention by the fact that a profile strip having two bearing surfaces each facing one of the wall parts is inserted in each case between two adjacent wall parts, that the bearing surfaces run at an angle to one another determining the angle between the wall parts, and that the profile strips are penetrated by clamping screws, the ends of which form an angle corresponding to the angle between the bearing surfaces. Profile strips and clamping screws of appropriate design are all that is needed to be chosen therefore to be able to assemble summerhouses of any desired basic shape.
