Patent DE-3309385-A1 (DE)
Title: Process and apparatus for wet mechanical sorting of fine-grained mineral raw materials
Inventor: SPRENGER HEINER
IPC: B03B5/68
Filed: 1983-03-16
Abstract: In the process, especially for materials of particle size less than 60  mu m according to the principle of table sorting, it is proposed that the sorting is performed in a centrifugal field. It is provided that the delivery of the sludge and the discharge of the sorted fractions take place continuously, that the table surface is continuously sprinkled with water, and that the continuous discharge of the heavy material fraction is supported by the addition of water.   An apparatus for this is characterised in that the table surface is the internal surface of a conical, rotationally symmetrical, rotating body. <IMAGE>

Title: Hammer blade for pendulum hammers with increased damping of interfering vibrations during dynamic material testing
Inventor: DONG XIAN-QUAN DIPL ING
IPC: G01N3/00
Filed: 1983-03-19
Abstract: In the instrumented notch impact bending test, the transient impact force/time or impact force/distance curves are assessed. The high-frequency interfering vibrations which occur in this process and are superimposed on the impact force/time curves make an evaluation (possibly even an automated one) of the tests difficult and impair the reliability of the values found. A novel hammer blade was designed so that a damping material was also fitted and the geometry of the hammer blade was altered. This makes it possible substantially to eliminate the superimposed interfering vibrations, provided they are produced in the hammer blade itself, and their effect on the impact force/time curve. This makes possible an improved, reproducible and also automatable evaluation of the transient impact force/deformation diagram obtained from an instrumented impact test.

Title: Device for protecting against dazzle from the main beam of motor vehicles
Inventor: BOCK MANFRED DIPL ING
IPC: B60J3/06
Filed: 1983-04-13
Abstract: In order to provide protection against dazzle from the main beam of vehicles for car drivers at night, a device is proposed which permits only the lightwaves of the troublesome main beam from oncoming vehicles to be ''extinguished'' whilst the lightwaves of other position lamps such as for example dipped headlights, parking light, braking light and flasher light etc. remain visible to the motorist. The dangerous ''sightless'' driving after being dazzled, which according to the statistics causes serious accidents, is largely avoided by means of a device consisting of polarisation films whose barrier grid axes form a right angle with respect to one another, it being possible to mount one pole film in the form of a foldable visor at the level of sight of the driver, preferably on the existing sun visor, and the other pole film completely or partially covering filament lamps or cover glasses of the headlights. In use, the oscillations of the headlight beams by the pole film arranged on or in the headlight are deflected into an oscillation plane and are ''extinguished'' at the pole film with transversely directed pole grid in the visual region of the driver when the visor is folded down. Likewise, all non-metallic reflections, e.g. reflections from the carriageway, can be filtered out with the aid of this visor.

Title: Structural reinforcing means
IPC: B65D81/02
Filed: 1983-04-30
Abstract: This invention is characterised by hollow bodies which, with different sizes and shapes, give a similar impression to soapsud structures. Such soapsud structure-like hollow body compositions, which can preferably be made from flexible materials, are characterised especially in that they fulfil such different functions as reinforcing means or filling material. By providing hollow bodies with magnetic properties or a mutual adhesiveness, such hollow bodies can be packed together to form a compact structure. Such a packing together of hollow bodies can serve to fill hollow walls or to fill cavities of the most diverse kinds. Particularly important fields of application include the areas of transport and packaging, the replacement of foam materials as packaging materials or filling materials by elastic hollow bodies according to this patent description, because the concept described here is suitable at any time for filling either with supporting air or can be emptied again at any time, which is not possible with conventional foams. Using the novel automatic closure valves presented in this patent application, coherent hollow bodies can vary their internal pressure by means of external pressure, if flow passages are provided. On the other hand hollow bodies can ... Original abstract incomplete.

Title: Electric tool
Inventor: MOEHRING HERMANN ING GRAD
IPC: B25D17/04
Filed: 1984-01-11
Abstract: An electric tool (1) with an actuating device (3) which has an adjusting means (11) for adjusting a limit speed of its drive motor is proposed. Here, a trigger (4) can be set in its distance from a fixed end stop by the adjusting means (11), which establishes various switch-on displacements. The setting can be read off at a mark (10) on the side of the trigger (4). The trigger (4) is so long that at least two fingers (37 to 40) find space on it next to one another. It is mounted in a handle (2) of the electric tool (1) and matches the easy-to-grip handle shape. All fingers (37 to 40) opposed to the thumb of the holding hand can keep hold of the electric tool. In the process, the strongest fingers keep the trigger (4) switched on. The trigger (4) carries the adjusting means (11), which can be released and adjusted by one finger (37) during operation. The hand working in this way does not tire so quickly. A locking slide (28) can be moved transversely to the trigger (4) and is carried by it. It cannot therefore be adjusted unintentionally. <IMAGE>

Title: Sound-absorbing building panel for ceilings and walls
Inventor: FEHT FRIEDRICH
IPC: E04B9/04
Filed: 1984-06-08
Abstract: On the visible side (2) of the building panel (B1) there are grooves (4) which have side walls diverging towards the inside of the panel. On the side edges, parallel to the grooves (4), of the building panel (B1) there are rebates (16) which have the cross-section of half a groove (4), with the result that two rebates (16) of neighbouring building panels (B1) complement each other to form a groove (4). As a result of the divergence of the grooves (4), the panel (B1) is open to a large extent and a high degree of absorption thus results, even with a relatively small number of grooves. Due to the divergence of the side walls of the grooves, the latter are invisible, with the result that dirt in the side walls of the grooves is not a cause for annoyance. <IMAGE>

Title: Spring pressure brake releasable by electromagnetic means
Inventor: DOERPINGHAUS GERD DIPL ING
IPC: F16D55/00
Filed: 1984-07-04
Abstract: In a spring pressure brake releasable by electromagnetic means, electromagnets are provided in magnet housings, acting on associated axially movable armature plates and, counter to the action of brake springs, moving the said plates away from a friction disc, the rotation of which is to be halted for braking purposes. In order to obtain a compact design and finely graduated control of the braking torque, it is proposed to divide the armature plate into a plurality of segment-like portions which are spring-loaded independently of one another, are axially movable and lie in a common plane. In a corresponding manner, the magnet block is fitted with a collection of electromagnets which can be switched on and off independently, lie in a common plane of action and are each associated individually or as part of a group with one of these segments.

Title: Method and device for determining positionally and temporally variable birefringence
Inventor: BERGNER JOACHIM
IPC: G01N21/23
Filed: 1984-12-17
Abstract: The method and device according to the invention for determining positionally and temporally variable birefringence are used in determining the degree of alignment in polymer materials, which can be calculated via the birefringence, and in the microscopic analysis of kinetic processes, for example in crystallisation processes. The purpose of the invention is the automatic detection of the birefringence values measured, in order to be able to register them continuously or to use them to trigger control signals for processing machines. The object of the invention is to convert the optically perceptible changes in the measuring field of a polarisation device upon temporal or positional changes of birefringence into electrical signals of such a type as to permit continuous registration of the values and to be able to serve as the manipulated variable for controlling the processing of, for example, polymer materials. The object is achieved by the temporal or positional attitude change, which is associated with the change in birefringence, of the compensation strip in the measuring field being detected by a sensor and being used to control an actuator to change the compensator plate position. The compensator plate position is used to determine the phase difference.

Title: Method for overcoming the problems of a strip sabre in the production of helical-seam tubes
Inventor: KRAKOW HEINZ DIPL ING
IPC: B21C37/12
Filed: 1985-01-10
Abstract: The invention is intended to eliminate the problems encountered in the processing of sabre-shaped strips (strips with a lateral curvature). The invention eliminates the following problems: the lateral jamming in the uncoiling station (Fig. 2, Item 1), the compression of the strip-edge guide rollers (Items 5 and 6) and the risk that the strip will not run uniformly through the circular-blade shears (Item 9). The solution is as follows:     The uncoiling station (Item 1) is of pivotable design. The pivot (Item 3) is situated in the plane of the strip edge guide rollers (Items 5 and 6). The base plate (Item 4), which supports the uncoiling station (Item 1) can be displaced sideways. Pivoting of the decoiling station (Item 1) with a predeterminable pressure on the strip-edge guide rollers (Items 5 and 6). Measurement of the width of the scrap strip (Item 11) of the circular-blade shears (Item 9).   If the preselected width of the scrap strip is exceeded or undershot, the base plate (Item 4) with the uncoiling station is adjusted sideways in a corresponding manner. This gives a constant width of the scrap strip. Result: A trouble-free production process. Applications: In all helical-seam tube plants. <IMAGE>

Title: Dispersion adhesive
Inventor: NETZER WOLFGANG
IPC: C09J131/04
Filed: 1985-01-21
Abstract: The invention relates to a dispersion adhesive which contains an aqueous polymer dispersion as base component and is used, inter alia, as dowel glue. In an adhesive of this type, the aim is that it does not drip when introduced into the dowel holes and does not dry, even partially, thus losing its adhesive or bonding properties, for an extended period. This main aim is achieved if the proportion of polymer dispersion, for example based on polyvinyl acetate, is up to 90% of the total weight, and from 1 to 2% of pyrogenic silicic acid and from 4 to 15% of a high-boiling solvent, for example butyl diglycol acetate, are added to this base component.
