Title: Apparatus for the sink-swim separation of mineral raw materials
Inventor: STRAUSS WERNER
IPC: B03B5/42
Filed: 1983-07-27
Abstract: In a known apparatus for the sink-swim separation of mineral raw materials, especially coal, according to density by means of a liquid, especially a heavy sludge, the said apparatus consisting of a separating container with a lifting wheel rotationally arranged therein for the extraction of the sinking material, the lifting wheel is mounted on support rollers. This has the disadvantage that the lifting wheel must be designed to be very stiff and heavy, in order to take up without deformation the forces originating from the weight of the lifting wheel itself and the loading with sinking material in the region of the places of contact with the support wheels. In contrast to this, the invention provides an apparatus of light construction for sink-swim separation which is moreover very simply constructed. This is achieved by the lifting wheel (2), which consists of a cylindrical lifting wheel casing (3) with two circular annular end walls (4), being rotatably held, suspended in the separation container (1), via an endless support belt (7) which largely embraces the lifting wheel casing (3) and a support roller (9) arranged above the lifting wheel casing (3). <IMAGE>

With the aid of this code word, authorisation can be checked on the one hand while, on the other hand, the charges incurred during a videotex connection can be apportioned to the respective user.
Patent DE-3330831-A1 (DE)
Title: Process for producing ceramic transfer images (decals)
Inventor: KLUGE KARL-HEINZ DIPL ING
IPC: B44C1/17
Filed: 1983-08-26
Abstract: The invention relates to a process for producing ceramic transfer images in which a backing material is covered with a release layer, the decorative print is applied colour for colour onto this backing layer by the screen printing process and this decorative print is covered with a protective and transfer film containing solvent, UV-hardenable acrylates being used as printing aids for the ceramic decorative colouring body and each colour being hardened by UV radiation after the application. The invention is intended to avoid the disadvantage associated with these known transfer images that, in the image-free regions covered by the protective and transfer film, the solvents contained in the film effect such a strong adhesion to the substrate that the film cannot be peeled off there. This is achieved according to the invention by adding a release agent to the protective and transfer film, preferably consisting of polyolefins, fatty acid amides, castor oil or the like. Transfer images of this kind are used for decorating ceramics, porcelain, earthenware, glass and enamel.
Patent DE-3331704-A1 (DE)
Title: Electromechanical correction element with a differential function
IPC: G05B13/00
Filed: 1983-09-02
Abstract: In order to create an additional, optimising control or regulation range, the electromechanical correction element is installed in existing control or regulation rods and moves in a reciprocating manner with said rods over the predetermined control or regulation movement. Both when at rest and during these control or regulation movements, the correction element executes changes in the rod length and hence optimising control or regulation movement changes, corresponding to the correction pulses to be superimposed from various monitoring apparatuses, by means of a reversible drive motor. The correction element is designed such that it can extend control or regulation movements of 10 to 90 mm by a maximum of 15%, or shorten them by 10%.   These various control or regulation movements of 10 to 90 mm are taken into the correction element via an adjusting lever, which is fixed via a tension rod, and lead there to a differential function which releases, or also limits, the associated additional and optimising control or regulation range limits (+ 15%/- 10%) precisely to these various control or regulation movements. If these range limits are exceeded, feedback in the +/-0 direction takes place automatically. It is possible to use the correction element in the case of control or regulation movements of more than 90 mm and to set other limits (for example +/-20%). <IMAGE>
