Title: Grinding apparatus
Inventor: DEMEL GERHARD
IPC: B02C17/14
Filed: 1984-02-11
Abstract: Gyratory crushers, impact crushers, hammer crushers or roller crushers are used for the comminution of lump-size materials. These known crusher units are relatively costly in their constructional design and moreover do not make possible the comminution of materials under sterile, contamination-free conditions and/or at extreme temperatures. However, according to the invention the comminution of lump-size materials is made possible in a particularly simple manner by at least one grinding container (1,19,25) which is mounted so that it can vibrate, is provided with imbalance exciters (6), and has an upper material feed (3) and a delivery outlet (4) situated essentially perpendicularly below this for the comminuted materials, grinding bodies (8,16,18,22) being loosely arranged, running parallel to the axis of the imbalance exciters (7) and at a distance (a,a',b,c,d,e) from each other, in the grinding container (1,19,25). <IMAGE>

Title: Plane blade, in particular profile blade
Inventor: BERGLER OTTO
IPC: B27G13/04
Filed: 1984-02-16
Abstract: A plane blade is described, in particular a profile blade for rotating plane and router heads which consist of a driven centre piece and of clamping flaps which are arranged symmetrically to the rotational axis, are adapted to the profile of the plane blades and can be pressed by fastening screws against the blades and the centre piece. In this arrangement, means for positive-locking reception are provided on a supporting plate which is designed as a blade carrier and is adapted to the shape of the plane blade. A thin profile blade can thereby be held on the supporting plate in a centring and positive-locking manner. The cutting forces can be satisfactorily absorbed, and it also becomes possible to use thin blanks for the manufacture of the blades, on which blanks the cutting edges can be stamped by a non-cutting shaping process.
Patent DE-3405704-A1 (DE)
Title: Burnishing tool
Inventor: BERSTEIN GARRI DR ING
IPC: B24B39/02
Filed: 1984-02-17
Abstract: The invention relates to a burnishing tool for the internal machining of bores having large diameters, using burnishing rollers which can be positioned in a frictionally locking manner against the bore wall. Known tools of this type have only a very limited working range and must therefore be designed for the nominal diameter of a single workpiece bore and, because of their structure, are suitable only for the tolerance range of the nominal bore diameter. This makes it necessary in the case of neighbouring bore diameters to use a multiplicity of such tools. It is therefore intended to enlarge the working range of such tools, which is achieved by each burnishing roller (7, 8, 9) being arranged on a support (1, 2, 3) connected to a tool body (10-13) such that it moves in at least the radial direction. Each support (1, 2, 3) is supported directly, or via associated intermediate pieces (51-56), against a surface, inclined with respect to a longitudinal axis (44) of a bore (43), of a spreader piece (39, 40, 46) which is guided displaceably in the direction of the longitudinal axis (44). The spreader piece (39, 40, 46) can additionally be movable in the radial direction. <IMAGE>

Patent DE-3431764-A1 (DE)
Title: Method and apparatus for the rapid measurement of the thickness of a film
Inventor: BUHL HOLGER
IPC: G01B15/02
Filed: 1984-08-29
Abstract: In the production of film, there is a problem in ensuring a uniform thickness of the film. In order to be able to adjust the film production apparatus, it is important to obtain operationally reliable measurements of the thickness at relatively short intervals. The film thickness is measured by directing a  beta -radiation source (11), such as a 10 mCi Sr-90, against the film (64) and by measuring the reflected radiation using a scintillation detector (12). The signal from the detector is integrated at a given interval and the integration value is a measure of the film thickness. Such a measurement has considerable uncertainty. The shorter the interval, the greater the uncertainty. Since both rapid and operationally reliable measurements are required, two integration intervals of different length are used, a relatively short interval and a relatively long interval (14, 15). The first interval provides a large number of measurements which have a high uncertainty. The second interval ensures more accurate results. The measurement results are assessed and compared in a microcomputer (16), the slow but operationally reliable measurements being used for correction of the rapid measurements which are operationally reliable. <IMAGE>

Title: Prepared polygonal selection input disc and round selection input disc
Inventor: HEINEMANN GERD
IPC: G05B19/10
Filed: 1985-01-18
Abstract: To simplify and accelerate the program selection possibilities and program triggering mechanisms used, which are needed for running various predetermined programs in, in particular, self-service points, automatic goods dispensers and apparatuses, the polygonal or round selection input disc marked on the sides and tangents is provided with a function-triggering preparation of a selection-determining and a selection-triggering part. The selection input disc contains the program selection in the marking of the sides or tangents. The determination and the triggering of the individual predetermined programs are effected in the associated selection receiving housing, selection receiving core or a selection receiving device adapted to the selection input disc, by deliberate coincidence of the conductive material incorporated in the selection input disc with the program-connecting wait contact or wait mechanism arranged in the selection receiving housing, the selection receiving core or in the selection receiving device. The selection input disc with a preparation on one side half or tangent half has the advantage that, by using the top and bottom, twice the number of program sequences as with a selection input disc prepared on one side or tangent can be achieved.

Title: Electronic switch having DC potential isolation, and its use
Inventor: WETZEL KLAUS ING GRAD
IPC: H03K17/95
Filed: 1985-03-29
Abstract: In the case of a switch, in order achieve DC potential isolation without an auxiliary voltage in the control circuit, a design is proposed which has been developed from an inductive proximity switch. It is known for a proximity switch to be connected by damping the inductance of a tuned circuit; the damping in this case takes place by moving a metal plate into the vicinity of the inductance. In the case of the proposed switch type, the inductance (5, 6) is produced by producing a short-circuit in an air-cored coil (1) which is located at a predetermined distance from the tuned-circuit inductance. The switch is preferably used in a floor vacuum cleaner, the short-circuiting switch (4) being located in the suction tube (15), the air-cord coil (1) in the suction hose (17) and the tuned-circuit inductance (5, 6) together with the downstream-connected electronics (7) in the apparatus housing (18). Advantages: the leads (2, 3) which are carried in the hose are cheap, flexible and thin and there is no need for a plug connection to the main apparatus. <IMAGE>
