Title: Sorting device
Inventor: NIENSTEDT HEINZ
IPC: B07B9/00
Filed: 1982-05-07
Abstract: The invention relates to a device for sorting small items of different sizes such as screws, screw nuts, spring washers, rail attachment plates and small packets made up of the latter. The items are transported via a belt conveyor in the form of a continuous belt whose holes have a diameter corresponding to the circumference of the smallest items and by means of a further conveyor which has parallel rods or cables, in which conveyor the rods or cables are mutually spaced in such a way that items of average size can fall through but the large items cannot. Depending on the series in which the two conveyors are arranged one behind the other in the conveying direction, initially only the smallest items or the smallest and average-sized items are separated off from the other items. <IMAGE>

Patent DE-3227070-A1 (DE)
Title: Roller on a belt conveyor
Inventor: LEGNER KARL-HEINZ
IPC: B65G39/071
Filed: 1982-07-20
Abstract: The invention relates to a roller on a continuous conveyor with a belt which bears an inflatable covering as support. During operation, flexing work leads to a stretching and compressing of the covering causing impurities and incrustations to break up and flake off; the roller is therefore self-cleaning. It also has good noise-reducing characteristics and produces little noise during operation.

Patent DE-3230098-A1 (DE)
Title: Device for detachably connecting light guides, light guide ribbons and light guide bundles
Inventor: BEHRENS HERBERT
IPC: G02B6/40
Filed: 1982-08-13
Abstract: The coupling of light guides requires not only good mechanical connections - it is also of very particular importance to guarantee good optical couplings in order for information present in the form of light to be able to pass with as little loss as possible from one light guide to the next. Plug-in connectors have already become known for this purpose, which require high expenditure on production, installation and adjustment and are therefore less suitable for cheap mass production. The object of the invention consists in providing a connecting device for connecting a fixedly arranged light guide (5) to a light guide consisting of a flexible optical fibre (3), which can be produced cheaply and largely independently of the tolerances of the light guides that are to be connected, and requires no adjustment operations for precisely opposing the light guides (3, 5). This is achieved according to the invention when the connecting device has a support device (43) by means of which the free end of the optical fibre (3) to be coupled can be clamped in such a way that the end faces of the two light guides (3, 5) always bear against one another under pretension after the coupling. This coupling is greatly facilitated by a two-part, resilient joint box (21) by means of which damage to the light guides (3, 5) is reliably avoided during transport or installation. <IMAGE>
Patent DE-3230122-A1 (DE)
Title: Suction-pipe heating device
Inventor: ROHLFING HANS DIPL ING
IPC: F02M31/10
Filed: 1982-08-13
Abstract: The invention relates to a device for heating the suction pipe of a mixture-intake internal-combustion engine, having a heating point which is arranged in the wall of the suction pipe below the fuel-metering device and which is formed by a heating plate heatable both electrically and by the cooling water of the internal-combustion engine. To achieve an effective heating of the mixture, especially during cold starting and the running-up phase of the internal-combustion engine, the heating of the heating plate is to take place first electrically and solely by the cooling water only after a sufficiently high temperature of the latter has been reached. In order, at the same time, to prevent a dissipation of heat from the electrical heating to the cooling water, there is to be inserted between the cooling water and the heating plate (1) a heat-transmission means (4) which makes a heat-conducting connection between the cooling water and the heating plate only when a predetermined temperature of the cooling water is reached. <IMAGE>

Filed: 1982-09-02
Abstract: A method is described for the hydrogenation of heavy and residue oils in the liquid phase and catalysts used therefor which are obtained both by coking brown coal, in particular in an open hearth furnace, and by brown-coal gasification in a high-temperature Winkler generator, and which are doped with metal compounds, particularly of iron, for further improvement of their catalyst properties.
Patent DE-3234373-A1 (DE)
Inventor: HOFSAESS PETER
IPC: H01H81/02
Filed: 1982-09-16
Abstract: For stopping drift or other undesired changes in the response temperatures of a thermal switch using a bimetallic element for driving a moving contact, the design is such that the moving contact and a counter-contact are supported on a common insulating supporting part and the counter-contact is elastically and yieldingly fixed on the supporting part. The lengths of the bimetallic element and of the a strip supporting the counter-contact that may be moved are different to each other so that the two contacts will make contact at different points thereon and with a rubbing effect for clearing oxide and other undesired coatings forming on the said contacts. For producing such a thermal switch with multiple functions, for example the functions of a temperature automatic controller and a thermal protective device, the counter-contact, that is placed so that it may give way elastically, is acted upon by a further bimetallic element.

Patent DE-3239670-A1 (DE)
Title: Resilient floor, especially for sports halls and gymnasia
Inventor: HOESS KLAUS-DIETER ALBERT DIPL
IPC: E04F15/22
Filed: 1982-10-27
Abstract: In a resilient floor, especially for sports halls and gymnasia, the residual deflection at a preset distance from the point of impact of the load must not exceed a given value. With the previously known resilient floors, in which upper sprung bridges are laid in the same direction as lower sprung bridges, in particular the upper sprung bridges being situated on top of the lower sprung bridges, the required value cannot be reached. However, the resilient floor displays the required resilient behaviour if the upper sprung bridges (2) are arranged transversely to the lower sprung bridges (1) and a resilient block (6, 7; 10, 11) is situated at each crossing point of the sprung bridges. This is the case in particular if the supporting blocks of the lower sprung bridges (1) are designed as resilient blocks (6, 7). This floor then requires no counter floor and, in fact, the floor covering (3) of plates or webs can be supported directly on the upper sprung bridges (2). <IMAGE>

Title: Method and arrangement for controlling a stepping motor
Inventor: KRAPP MICHAEL DR ING
IPC: H02P8/14
Filed: 1982-11-04
Abstract: The invention relates to a method for controlling a stepping motor in check-back operation, in which check-back signals from an angle measuring system which is mounted rigidly on the rotor are compared in their phase with control signals for the instantaneous angle characteristic shift. Any desired speed responses with respect to time are reliably implemented in load conditions which are less than critical, and dynamic or static overloads do not cause mechanical instability. The method is implemented exclusively using digital circuit technology means. <IMAGE>

Title: Fluidised separator for separating impurities from suspensions of solids
Inventor: SELBHERR ANTON
IPC: B04C5/13
Filed: 1982-12-24
Abstract: The fluidised separator contains a head part (2) which widens conically downwards and emerges with a downwardly conically tapering separator part (3). The head part (2) is connected to a feed channel (7), which leads in horizontally in the circumferential direction, for the solid suspension to be purified and contains a central discharge channel (8) for useful material, which channel (8) leads out of the head part (2) at the top. The head part (2) has in the circumferential area adjacent to the feed channel (7) a guide wall (18) which extends with an increasing degree of inclination towards the inside in the direction of flow of the solid suspension to be purified or in the circumferential direction, the lower boundary of which guide wall (18) follows a circular arc-shaped circumferential line (19) and the upper boundary of which is determined by a reference line (20) which tapers in a spiral shape in the circumferential direction. By means of this guide wall (18), the solid suspension to be purified is deflected downwards in a helical line-shaped flow without using movable parts. In order to reinforce this effect, the head part (2) can have an upper end wall (21) which is constructed in the manner of a helicoid. <IMAGE>

Patent DE-3317352-A1 (DE)
Inventor: BUGIEL HORST GEORG DIPL ING
IPC: F42B1/02
Filed: 1983-05-13
Abstract: An insert for a projectile-forming charge with a non-constant or varying material thickness extending in the centripetal direction thereof. The insert incorporates peripherally mutually offset centripetally extending zones with a material thickness which is constant in the centripetal direction, and which alternates in transition with centripetally extending zones having a non-constant varying material thickness. In the interest of an improved combat effectiveness for large-caliber ammunition, notwithstanding greater target distances, through periodically varying the material thickness of the insert in the peripheral direction, during the folding in of the insert projectile there can be achieved a more stable flight trajectory due to the formation of defined stub wings at the tail end of the projectile.

Title: Disc friction clutch with pressure plate function integrated into the clutch disc
Inventor: SCHEER ERICH
IPC: F16D23/14
Filed: 1983-07-13
Abstract: The invention relates to a disc friction clutch, in which the flywheel and the contact pressure plate are fixed together. In order to produce the contact pressure and the air movement, the diaphragm spring is incorporated between the two friction rings into the clutch disc. At the same time the one cover plate is designed as supporting element, on which the diaphragm spring is supported on its mean diameter thereby fixing its tilting circle. The diaphragm spring now acts on a greater or smaller diameter on the rear side of the two friction rings in order to produce the contact pressure. For disengagement the diaphragm spring is swivelled by way of its diaphragm spring tongues about the tilting circle so that both friction rings can simultaneously perform an essentially equal air movement.
