Patent DE-3707566-A1 (DE)
Title: Changeable container chassis for a semitrailer of a semitrailer train
Inventor: GERDES BERTHOLD
IPC: B60P1/64
Filed: 1987-03-10
Abstract: The advantage of the invention emerges from the fact that henceforth only one container chassis has to be used for variously sized containers. The main features of the invention emerge from the fact that the movable slide serves to change the mounting surface. A further feature of the design is the manner in which the slide is moved. A design of this type has until now not been available. Only the tractor is needed in order to move the slide on the chassis. By moving the tractor back and forth, the slide is moved, after the vehicle frame has been lowered by the air suspension, by virtue of the wheels of the trailer revolving. A further relevant feature of the invention is the fact that a foldable underride guard is mounted on the movable slide. The foldable underride guard can fulfil two functions. On the one hand, when the slide is in an appropriate position, it acts as an underride guard. When the slide is in a different position, it serves as a wheel guard for the third axle. The invention simplifies the transportation of containers of various sizes.

Title: Device for the alteration or repair and retouching of injection moulds on the injection moulding machine
Inventor: HUMMEL MANFRED KARL
IPC: B29C45/17
Filed: 1987-05-28
Abstract: The device according to the invention can be releasably attached to any horizontal injection moulding machine and enables the mould manufacturer to provide the injection moulder with complete moulds for the series production of workpieces without having to expect that the injection moulder will send the moulds back to him, after the preparation of rejects, for the purpose of modification. The device enables the mould manufacturer also to carry out the retouching of moulds, which is customarily carried out on a retouching press, on the device. For the retouching and modification work, the mould can remain in the operating position on the mounting plate of the device. In the use of the device, the mould may thus remain in a clamped position on the injection moulding machine for the subsequent operations: retouching, optimising, injection moulding of samples, modifying and completing the mould for the series production of workpieces. The device according to the invention is time-saving and cost-saving to a significant degree compared with the customary process in which retouching processes are necessary and the sending of the moulds back and forth between the injection moulder and mould manufacturer is customary. <IMAGE>
Patent DE-3720174-A1 (DE)
Title: Method of automatically welding workpieces
Inventor: KRAUS GERHARD
IPC: B23K37/04
Filed: 1987-06-16
Abstract: The invention deals with the automatic welding of workpieces by means of industrial robots. In contrast to the teaching of German Offenlegungsschrift 2442725 in which a workpiece has to be moved by a manipulator and the welding torch has to be moved by an industrial robot for the automatic welding, the invention provides for the welding torch to be constantly held stationary in a vertical position. The workpiece, however, is seized, centred and held in place by the hand of an industrial robot and is then put into the most favourable welding position, whereupon the workpiece movement typical of the welding is performed by means of the same industrial robot along the stationary welding torch. It is important here that the workpiece is always held in such a way that the welding line lies on the top side of the workpiece. Because the arc of the welding torch is constantly acting downwards, the welding pool is maintained and does not run away. The workpiece is always located in a so-called gravity position.

Title: Return control device
Inventor: HOFBAUER PETER PROF DR ING
IPC: F02B3/06
Filed: 1987-08-11
Abstract: A device for temperature-dependent control of the return of the excess fuel from a diesel injection pump (1) is described with a control valve (7) which, as a function of the temperature of the fuel, connects a return line (6), returning the excess fuel from the injection pump, either to an outlet line (8) leading to a fuel tank (4) or to a feed line (2) leading by way of a filter (3) to the injection pump (1). In order to reliably prevent clogging of the filter due to the formation of paraffin wax occurring in the fuel at low temperatures, it is proposed that the control valve (7) be controllable as a function of the fuel temperature prevailing in the feedline (2) downstream of the point of addition of the excess fuel. For this purpose it is proposed that the control valve have a control piston (12), which can be acted upon by a differential pressure, connectable as a function of the fuel temperature. It is proposed that at least one control valve (10) be usefully provided with a bimetal element (11) in thermal contact with the fuel flowing through the feedline (2), which element connects at least one pressure admission chamber (15, 17), assigned to the control piston (12), to the feedline (2) as a function of the temperature (Figure 1). <IMAGE>

Title: Process and apparatus for generating CO2 by fermentation of a sugar solution and for enrichment of aquarium water therewith
Inventor: LANGENBRUCH PAUL-FRIEDRICH DR
IPC: A01K63/04
Filed: 1987-09-21
Abstract: The invention "Process and apparatus for generating CO2 gas by fermentation of a sugar solution and for enriching aquarium water therewith" makes possible, with optimal utilisation of the sugar to be fermented, a long-term uniform CO2 generation by fermentation at a low level and an enrichment of the aquarium water in accordance with the CO2 requirement with a high degree of utilisation of the CO2 gas generated by a diffusion apparatus having a metering apparatus which is simple to handle. The CO2 gas generated in a fermentation vessel is dissolved in the aquarium water in this case by means of a diffusion apparatus having diffusion chambers arranged one above the other in the manner of a cascade, the amount of CO2 to be brought into solution in the aquarium water being dosed, in the case of continuously flowing gas, by connection and disconnection of the diffusion chambers. The CO2 gas introduced into one of the diffusion chambers rises from chamber to chamber according to their overflows, a separation of CO2 gas and a foreign diffusing in gas taking place, and the foreign gas being released to the atmosphere on overflowing the top diffusion chamber. In the interior of the fermentation vessel the sedimenting micro-organisms lie in a low layer thickness in a temperature range preset to be constant, horizontally on large surface area plates, vibrations which prolong fermentation being preferably introduced.

Title: Biological insecticide spray containing black pepper oil
Inventor: LEKIM DAC DR
IPC: A01N65/12
Filed: 1987-10-05
Abstract: The invention is based on the object of increasing the activity and the storage stability of pyrethrin as an insecticide spray by means of biological synergists and improved formulation. An insecticide spray formulation is described, characterised in that the formulation consists of a mixture of pyrethrin extract, black pepper oil, additives with or without other ethereal oils and piperonyl butoxide, and is brought into a clear, aqueous emulsion and buffered at a pH of 3.0 to 5.0. An insecticide formulation of this type is readily biodegradable, non-toxic for warm-blooded animals and very stable on storage. It was found that a mixture of pyrethrin and black pepper oil excels the insecticidal action of the two components by far and is highly effective against insects, as was demonstrated by field tests.

Title: Deburring device for an industrial robot
Inventor: BERGER KLAUS DIPL ING
IPC: B24B41/00
Filed: 1987-11-13
Abstract: The invention relates to a deburring device for an industrial robot having a multi-section work arm. The drive motor of the deburring cutter and the deburring cutter itself are mounted inside the deburring device such that the cutter axis is inclined with respect to the axis of rotation of the end section, and the working point of the deburring cutter lies on the axis of rotation of the end section; in addition, the mounting is provided with a defined flexibility, so that the deburring cutter is able to yield to the workpiece contour to be deburred in the event of unexpected elevations. In order also, in the case of edges which are unfavourably located within the workpiece and are to be deburred, to be able to reach these edges in an unimpeded fashion using the deburring device or the deburring cutter, without having to re-position the entire work arm of the industrial robot, a circular-arc-shaped guide concentric with the working point of the deburring cutter is provided inside the deburring device. The mounting of the drive motor is displaceable by means of a corresponding slide along said guide. As a result, the angle between cutter axis and axis of rotation of end section can be altered without thereby altering the position of the working point and/or the position of the axis of rotation of the end section. The slide is equipped with a controllable adjusting drive and with a remotely controllable clamping device for eliminating a guide play. Expediently, the adjusting drive and the slide-clamping device are ... structurally to a single part ... functionally ... Original abstract incomplete.
