Title: Process for removing alkaline earth metal chlorides from iron ores
Inventor: EL GAMMAL TAREK PROF DR ING
IPC: C22B1/00
Filed: 1984-01-17
Abstract: By means of this invention, chloride-containing salts, for example sodium chloride and potassium chloride, present in the iron ore are to be removed by thermal treatment. According to the invention, the iron ores are to be treated in an inert or low-oxygen atmosphere, preferably at temperatures between 900 and 1100 DEG C, in a suitable vessel, for example a rotary kiln, fluidised bed or partially closed travelling sintering bed. The oxygen potential in the vessel space can be adjusted by controlled combustion of gaseous, liquid or solid fuels and/or by the addition of carbon to the iron ore mixture.
Patent DE-3401836-A1 (DE)
Title: Sealing head
Inventor: VLASMAN ROBERT
IPC: B67B3/20
Filed: 1984-01-20
Abstract: The invention relates to a sealing head for turning a screw cap onto a threaded opening, for example of a bottle, in which the container is fed to the constantly rotating sealing head from below, and raises it. Such sealing heads are known in a variety of embodiments, but have the disadvantage that difficulties arise as a result of different torques on the screw cap when tolerances between the container head and the screw cap are unfavourable. The invention aims to eliminate this disadvantage by arranging a rubber bellows in the sleeve of the sealing head and by connecting the free space between the sleeve and the rubber bellows, which is sealed off from the outside, to a compressed air feeding device. By feeding compressed air, the rubber bellows are pressed against the screw cap and are able to tighten the latter, regardless of the different torques on the cap.
Patent DE-3402124-A1 (DE)
Title: Labelling device
Inventor: HALBO HANSJOERG
IPC: B65C9/16
Filed: 1984-01-23
Abstract: In a labelling device with a plurality of rotating or oscillating removal elements (4) which are arranged on a rotor (3) and which interact with a rotating gluing roller (5), a stationary label holder (8), a rotating stamping head (9) for the labels and a rotating gripper cylinder (12), the radius of curvature of the adhesive surfaces (29) formed on a flexible plate (28) is adjustable. The radius of curvature is controlled during a revolution of the rotor in such a way that it reaches a maximum value (R) when an adhesive surface is rolling off onto the gluing roller, the stamping head and the gripper cylinder and reaches a minimum value (r) during rolling off onto the stack of labels in the label container. In this way, precise rolling off of the adhesive surfaces onto the rotating treatment elements without additional rotation is possible on the one hand, and an especially closely packed arrangement of the removal elements on the rotor and therefore a high output at a low speed of transport is possible on the other hand. <IMAGE>
Patent DE-3402541-A1 (DE)
Title: Perforated block, in particular large building block
Inventor: RANK HORST
IPC: E04B2/14
Filed: 1984-01-26
Abstract: In the case of a perforated block (1) which exhibits a slotted perforation formed by webs (17, 18) and slots (11, 11', 11", etc.) extending transversely to the direction of heat flow (W) and combined to give rows of slots (12, 12', 12", etc.), those faces of the slots extending transversely to the direction of heat flow (W) are formed in each case by two part-faces (13, 13' and 14, 14') which are inclined at an obtuse angle ( alpha ) with respect to one another. In this way, the cross-sectional shape of the slots (11, 11', 11", etc.) is composed of two trapeziums (a, b) arranged opposite each other. This configuration means that the webs (17), running transversely to the direction of heat flow (W), are divided into individual web parts which are inclined with respect to one another in an approximately wave-shaped fashion, with the result that said web parts exhibit a high degree of elasticity. When firing and drying the blocks (1), changes in length can be compensated for by means of the elasticity, with the result that high strength is achieved. Through-flow also benefits from this shape of the slots. <IMAGE>

Title: Device for measuring temperatures in the interior of a moving reactor having a refractory inner lining
Inventor: POSSE GUENTHER
IPC: G01J5/04
Filed: 1984-04-18
Abstract: In measuring the temperature in the interior of a moving reactor, for example in the interior of a revolving cylindrical furnace, by means of thermocouples, contact wear leads to difficulties in transmitting the measured values with the aid of movable mechanical transmitting devices. The mechanical transmitting devices are very prone to failure. In accordance with the invention, these disadvantages are removed by means of a heat-conducting member (3, 4, 5, 6) which penetrates the reactor wall (2) and is optically connected for the purpose, in each case, of measuring the temperature to a radiometric instrument (7, 8) arranged opposite at a distance outside the reactor wall. <IMAGE>

Patent DE-3435954-A1 (DE)
Title: Flexible shaft coupling
Inventor: BARSCH HANS PETER DR
IPC: F16D3/78
Filed: 1984-09-29
Abstract: A flexible shaft coupling of annular or polygonal design which can have either metal sleeves or a star-shaped hub with metal sleeves arranged between the arms as connecting or fixing parts, is optimised in the region of the rubber columns extending between the connecting or fixing parts in such a way that, viewed in the longitudinal direction of the rubber columns, the centroid of area of the planes of section which can be laid transversely through the rubber columns is shifted radially towards the outside in the central regions of the said columns. This is accomplished by altering the cross-section, which can, for example, have an appearance such that a rectangular cross-section in the region of the fixing or connecting elements makes a transition in the central region of the rubber columns into a triangular cross-section. <IMAGE>

Title: System for connecting subscribers to a central station
Inventor: ALI AMAR DR ING
IPC: H04B10/272
Filed: 1984-10-16
Abstract: The invention relates to a system for connecting a multiplicity of subscribers (3) to a central station (1) via optical waveguides. The optical waveguides of physically adjacent subscribers are in each case coupled in an out-of-area device via wavelength multiplexers and demultiplexers to a common optical waveguide which is connected to the central station. A dedicated wavelength ( lambda 1 to  lambda n) is allocated to each subscriber. Through multiple use of the connection between the central station and the out-of-area device, albeit a purely passive optically selective out-of-area device, the costs of the system can be kept down, its reliability can be increased and its flexibility and extendability can be guaranteed. <IMAGE>

Title: Device for securing a rock-excavating machine used in mining
Inventor: KOPKA FRANCISZEK DIPL ING
IPC: E21C29/10
Filed: 1984-11-20
Abstract: In order to prevent a rock-excavating machine from rolling down the face in the event of the fracture of a double hauling chain which runs between roller blocks fastened to the face ends of an inclined working excavation, a pawl brake is fastened to the machine, through which pawl brake the securing bottom chain section runs, which is fastened at the face to the top roller block. The pawl brake has a pawl with which a spring-preloaded pin interacts, which sits on a lever which is connected to an actuating chain, via which the operator can release the engagement between the securing pin and the pawl, which then falls into an engagement position in the next horizontal chain link and thereby prevents a downwards movement of the machine. <IMAGE>
Patent DE-3442486-A1 (DE)
Title: Method and instrument for determining the viscosity of gases or liquids
Inventor: LAURENT MICHEL
IPC: G01N11/14
Filed: 1984-11-22
Abstract: A steel sphere having a diameter of several millimetres is set into rotation by the action of a magnetic rotary field. This is achieved by two Helmholtz coil pairs. The sphere, which rests on the bottom of a vessel which contains the liquid or the gas to be measured, as a function of the viscosity exerts a braking torque on the medium surrounding it, which is proportional to the viscosity of said medium. The sphere is set into constant rotation, whose rotational period is essentially proportional to the viscosity of the gas or the liquid to be measured. The rotation of the sphere can be made visible with the aid of refraction patterns which, for example, are generated by having a laser beam impinging on the sphere along its rotational axis.

Patent DE-3526379-A1 (DE)
Title: Pulsed washing and cleaning machine
IPC: A47L15/10
Filed: 1985-07-24
Abstract: The aim is to simplify and intensify washing and cleaning by forcing the water molecules to rub intensively against the material to be cleaned. To this end hot air and water are vortexed and a surge movement imposed on this mixture by means of a valve; this pressurized mixture decompresses in the chamber with the material to be cleaned. Extremely small sponges (or another material with similar properties) in the chamber have to rub so intensively against the material to be cleaned because at the same time the air can bubble up in a pulsed manner. The hot air is generated in the rotating threaded tube, the funnel-shape of which and the thread forcing the compressive air movement; the mixing-in of the hot air takes place in a further funnel-shaped, rotating threaded tube [sic].

Title: Self-closing hinged-cover support for an electrical installation apparatus, especially a plug socket
Inventor: RODEMANN BURKHARD
IPC: H01R13/447
Filed: 1985-08-29
Abstract: A self-closing hinged-cover support for electrical installation apparatuses, especially plug sockets, in the case of which the hinged cover is equipped with a leaf spring, one end of which is mounted on the inside of the hinged cover. The other end of the leaf spring is not connected to the intermediate cover until the hinged cover is installed on said intermediate cover, so that it is supported in a slot by a pin which is mounted in a stud on the intermediate cover. The rotational support of the hinged cover is effected via a further pin on the outside of the hinged cover. In this case, this pin engages in the hole of the opposite stud. The self-closing of the hinged cover is now effected in such a manner that the leaf spring is stressed by rotation when the hinged cover is opened so that the spring stress becomes effective when the cover is released, that is to say the self-closing of the hinged cover is effected. The hinged cover is also rotatably fixed on the recess side of the intermediate cover by means of a recess in the hinged cover opposite the rotating-pin support which encloses the pin on the stud.
