Patent DE-3543505-A1 (DE)
Title: Apparatus for metering powdered substances
Inventor: WALTER KURT
IPC: B65B1/28
Filed: 1985-12-10
Abstract: The apparatus is intended for the metering of powdered substances, especially into bag-like packages, via a filling pipe having a collecting hopper and devices for forming film bags. The apparatus comprises at least one metering cylinder which is arranged in a metering plate and has an upwardly acting discharging piston, a passage aperture which is aligned with the collecting hopper being arranged in the plate alongside the cylinder and a powder supply container which can be displaced transversely, with its lower aperture edge on the plate, up to the edge of the passage aperture and across the metering cylinder being arranged above the plate. In order to reduce the dropping height of the metered powder and to be able to reduce the amount of dust formed during this process, and therefore to reduce the operating cycle of the apparatus, the metering plate (1) is arranged together with the supply container (2) so as to reciprocate on a parallel guide (5) relative to the discharging piston (4) which is held in a stationary fashion on a support (3). <IMAGE>
Patent DE-3612991-A1 (DE)
Title: Apparatus for drawing
Inventor: BEYER HANS-KARL
IPC: G09B25/06
Filed: 1986-04-17
Abstract: In order to represent contours (2) on the landscape model (1), templates (3) are provided which are formed as negative part-moulds (4). The upper limiting rim (5) has a guide edge (6) on its inside, along which a writing pen (7) can be guided to transfer a contour onto the landscape model (1). As a result of the negative moulding of the landscape model (1), this guide edge (6) lies tightly on the outside of the model, so that even a writing pen guided at a different drawing angle does not result in any vertical fluctuations. The negative part-mould (4) may have a bearing flange (9) at its base which simultaneously forms a placement limitation, so that even relatively thin-walled landscape models are not deformed by the placement of the part-mould. Both the landscape model (1) and the part moulds (4) can be cheaply produced as thermoformed mouldings or injection mouldings. In order to represent different contours (2), a set of templates with different negative part-moulds (4) is advantageously provided. In the reversed position, these templates (3) can also be used to draw contours (2) on a flat drawing substrate. <IMAGE>

Title: Cutting-height and picking-height regulation for maize-harvesting machines
Inventor: DAVIER RUDOLF VON DIPL ING
IPC: A01D45/02
Filed: 1986-04-30
Abstract: For automatically regulating the working height of a maize-picking or cutting attachment, the divider tips customary for picking up and guiding the plant material are guided movably on a parallelogram-like linkage and slide on the ground by means of adjustable runners. The up-and-down movement of the divider tips is to act on a common shaft by means of levers and stops, the divider tip deflected furthest upwards determining the rotary position of the shaft, and this influencing the hydraulic system of the machine via a linkage or Bowden pull, in such a way that the maize-picking or cutting attachment is raised or lowered and thus follows the ground contour.

Title: Set of structural elements for erecting an annexe, and annexe erected therefrom
Inventor: PRIMUS ILLO-FRANK DIPL ING DR
IPC: E04B1/18
Filed: 1986-07-15
Abstract: The situation where buildings are provided subsequently with solid absorber apparatuses poses great difficulties and causes high costs. The invention thus proposes to accommodate the solid absorber apparatuses in an annexe. The intention is thereby to achieve as high an efficiency as possible without any great degree of intervention in the building being necessary. Proposed, for such an annexe, is a set of structural elements which contains, according to the invention, concrete structural parts (31, 33 to 36, 38 to 43) which are in the form of panels and/or beams and beneath the essentially vertically arranged main outer surfaces (53, 54) of which pipe coils (52) for receiving a heat-absorbing medium are concreted in. The pipe coils form, in each structural part, a closed absorber circuit which contains at least one shut-off valve (50) and, preferably, a heat pump. The prefabricated concrete compound units are expediently thermally insulated (37) with respect to the building (30). The invention also relates to the annexe erected from the set of structural elements. <IMAGE>

Title: Electric motor actuating element as an energy saving electric motor
Inventor: RUST PETER
IPC: H02K53/00
Filed: 1987-04-25
Abstract: The application for robust and long-life electric motors is considerably simplified. In this case, electric motors can be directly mounted, with their housings, on the part which is to be rotated. Complex control electronics are also obviated. When the electric motor housing is at rest, the electric motor rotor, which is supported on the impeller, still always rotates. The rotation speed of the part (for example throttle valve) to be rotated can be varied at any desired speed. If the electrical power supply is interrupted, the electric motor actuating element reacts immediately and rotates back to zero; even if the return springs were to break.

Title: System for the additional use of safely disposable high-pressure cutting oils on machine tools
Inventor: SCHWINDLING JOACHIM
IPC: C10M101/04
Filed: 1987-06-22
Abstract: The machine tools existing hitherto are usually designed for the use of cooling emulsions only. If, in addition, another cooling lubricant is required, it is applied either manually or not at all. Taking into account that the cooling lubricants must not mix with one another or contain very highly toxic components, a compromise is found in most cases, according to which only one cooling lubricant is used. The novel system should therefore present no disposal problems, be fittable as an add-on, and be physiologically and ecologically safe. The cutting oil should be vegetable-based and thus non-toxic. A cutting oil which consists of vegetable oil, alcohol, sulphur and EP additives, is converted into an aerosol by means of a controlled compressed-air pulse and can thus be used in addition to other substances. This system is suitable for any application on machine tools, in which very high cutting pressures are produced.
