Patent DE-3324498-A1 (DE)
Title: Tensioning device of a conveyor for a harvesting machine
Inventor: MCMILLEN KENNETH R
IPC: F16H7/08
Filed: 1983-07-07
Abstract: A spring-loaded tensioning pinion can move under the influence of the spring in one direction, in order to tension the conveyor band under the influence of a holding unit. In the opposite direction, however, the tensioning pinion is retained, so that the sag does not increase. For this, the holding unit has a bore which is somewhat larger than an element displacing the tensioning pinion. When the opposite movement increasing the sag occurs, the holding unit is brought into an oblique position, in which the relatively sharp edge of its bore wedges in the element at any point and therefore retains this against undesirable movement in reverse.

Title: Device for discharging static from objects
Inventor: ZELLER WOLFGANG
IPC: H05F3/04
Filed: 1983-07-27
Abstract: The invention relates to a device for discharging static from objects, such as, in particular, leading plastic, paper and textile webs or the like, having a metallic conductor which carries a high electrical voltage, having an insulating sheath which surrounds the conductor and wire coils, which are pushed on to the insulating sheath and whose ends project freely at right angles to the axis of the coils as tip electrodes, having an insulating body which holds the conductor and the coils, and having a metal sleeve which surrounds the insulating body and acts as an opposing electrode. In order to be able to generate relatively high static-discharging currents using such a device, it is proposed that a plurality of wire coils, of which at least one is provided with a tip electrode, are combined into groups and are electrically conductively connected to one another, and that the conductor is passed through the coils of the groups in a meandering form.

IPC: C02F1/52
Filed: 1984-01-28
Abstract: In order to provide a process and an apparatus for determining the dry matter content of a sludge and to create an application for controlling sludge dewatering which permit a reliable indirect dry matter content determination in the sludge feed stream in a simple manner, the dry matter content of the feed stream is determined from the volumetric flow rate in the outlet of the dewatering apparatus as a first parameter, the volumetric flow rate in the feed to the dewatering apparatus as a second parameter, the dry matter content in the thickened sludge outlet as a third parameter and the specific gravity of the solid sludge in the thickened sludge outlet according to the relationship <IMAGE> in a computing circuit. In accordance with the apparatus, inductive flow meters are used to measure the volumetric flow rates. A display and control signal is also obtained from this which can be used for the metered feed of flocculants to a sludge to be dewatered, the rate of flocculant addition being changed in accordance with the signal.
Patent DE-3405735-A1 (DE)
Title: Method for sealing a metallic cask for shipping and/or long-term storage of radioactive materials, and cask closed using the method
Inventor: BIENEK HEINZ DIPL ING
IPC: G21F5/12
Filed: 1984-02-17
Abstract: In a method for sealing a metallic cask (1) for shipping and/or long-term storage of radioactive materials which has a metallic sealing cover (4), in which the sealing cover is welded to the cask, the aim is to construct the welded joint without a separate thermal source for heating the joining surfaces at the cask and sealing cover to the melting temperature. According to the invention, the sealing cover (4) is welded to the cask (1) by the thermometallic reaction of a powder (P) which is introduced into a melting space bounded at least partially by the cover and cask and containing at least one metal oxide and a reducing agent. It is preferred to use a separate melting mould (6) for the smelting after the sealing cover has been mounted. It is also expedient for the welding seam boundary surfaces (1a, 4a) of the cask to enclose at the base of the welding seam an angle of  alpha  </= 45 DEG  with respect to a plane (E) perpendicular to the direction of the longitudinal extent of the cask, which essentially excludes the adhesion of slag particles to the joint surfaces. The application also relates to a cask which is sealed using the method according to the invention. <IMAGE>

Title: Method and device for maintaining a specific temperature in the outer casing of the drum of a magnetic separator, in particular a ring jacket separator
Inventor: HEIL HANS EMIL
IPC: B03C1/10
Filed: 1984-05-16
Abstract: In the magnetic separation of damp bulk materials, the machines may become caked and clogged up. It is favourable to heat the parts coming into contact with the damp material, such as for example the outer casing of the drum of a ring jacket separator. The heating takes place via the magnetic coils by converting electrical energy into heat. However, with increasing temperature the magnetic field is weakened and the separating effect of the magnetic separator is degraded. The magnetic separator must therefore be cooled. The invention permits a constant operating temperature to be established and kept constant for the outer casing of the drum of a magnetic separator. This is achieved according to the invention in that the amount of coolant is set in an infinitely controllable fashion. In this way, the heat produced in the magnetic coils can be utilised very advantageously and controlled in such a way that, on the one hand, the desired heating of the outer casing of the drum is achieved and, on the other hand, an excessively high, undesired thermal stressing of the magnetic coils is prevented.

Title: Electrically driven cut-off screwdriver
Inventor: STROEZEL REINHOLD
IPC: B25B23/147
Filed: 1984-06-30
Abstract: An electrically driven cut-off screwdriver suitable for multiple arrangement on a support (46) is proposed, the screwdriver spindle (19) of which, longitudinally displaceable for coupling to and uncoupling from a drive motor (5), can be actuated by means of a likewise longitudinally displaceable, spring-loaded operating pin (60). When the support (46) is moved into the working position, a splined shaft (55) intended for carrying the tool is pushed into a spindle-bearing housing (4). In the process, it presses the operating pin (60) towards the screwdriver spindle (19) via a coil spring (59) accommodated in it and engages the separating clutch (11, 29, 30, 31) of this screwdriver spindle (19) by displacing the same. When the support (46) has reached its working position and is held in place there as usual, the same coil spring (59) forces the splined shaft (55) to follow the screw head moving away from the support (46) when screwing in the screw. Thus a fully automatic screwing-in operation is also made possible for electrically driven cut-off screwdrivers in a simple manner.
