The metering screw 3 has the special feature that the ball-bearings 17, 18 are protected by air at superatmospheric pressure against the penetration of fine-particulate filler. <IMAGE>
Patent DE-3440897-A1 (DE)
Title: Safety belt, modified
IPC: B60R22/12
Filed: 1984-11-09
Abstract: When unlocking, the belt buckle is held in the hand and can be guided to the side without any problem. The unlocked part together with the belt thus no longer flies against the side window. The production costs can also be reduced, since the insertion part is a simple punched part 5 and needs no plastic sheathing. Also the belt buckle 4 needs no attachment part, just sliding slots through which the belt is pulled. Similarly, the anti-slip clip on the belt strap is dispensed with, as the half-round belt strap prevents unintentional slipping of the closing part. <IMAGE>

Title: Telecommunications system having a plurality of subscriber stations which access a transmission medium with a ring structure
Inventor: STRATEN GERNOT VON DER
IPC: H04L12/433
Filed: 1985-03-04
Abstract: In a local area network having a plurality of stations which access a unidirectional ring in which each station which wishes to transmit initially listens in to the ring line to determine whether a transmission process is already taking place there and, if the ring line is busy, waits for access until it receives access authorization by means of a token, if the ring line is free, the station which wishes to transmit accesses the ring line, in competition with other stations, with the risk of collision, if it does not already have an information packet in the ring which has been transmitted earlier and has been terminated by a token. If a collision is detected, the transmission of the information packet is interrupted and a collision packet is transmitted; on reception of such a collision packet, the ring is closed again and the station which wishes to transmit does not start to listen in to the ring line again until a randomly determined waiting-time interval has elapsed, unless it has already recognised a token and gained access.

In the corresponding plant, the rotary kiln (18) has means (27) for introducing oxygen into the firing chamber. <IMAGE>
Patent DE-3521495-A1 (DE)
Title: Videotex subscriber station
Inventor: KRAUSE JOACHIM
IPC: H04M11/04
Filed: 1985-06-13
Abstract: In a videotex subscriber station, input information must be entered manually via keys of a videotex keyboard in order to set up a videotex link. In the invention, the individual input information is stored in separate memories which can be read out by actuating a switch into the decoder. The switches can be actuated automatically by a dial-up device which is activated by an external signal, for example the alarm signal of an alarm system. When the external signal occurs, a videotex link can thus be set up completely automatically in order to signal, for example, an intrusion in a receiving station.

Patent DE-3532047-A1 (DE)
Inventor: BEYER ECKHARD DR
IPC: G01J1/42
Filed: 1985-09-09
Abstract: On a rotatably-mounted support (1), of which the rotation axis (2) is parallel to the laser beam, a wave-guide (4) is arranged radially. The outer end of the wave-guide crosses the laser beam (3) during a rotation of the support, and then detects, on each rotation a partial laser radiation beam. This partial beam is transmitted by means of the wave-guide to a detector (10) fixably arranged in the rotation axis of the support. The wave-guide is a tubular guide or optical fibre. Using a stepping motor it is possible to displace in parallel the rotation axis of the support in order to detect the complete beam profile by means of a plurality of intersections with the latter. Instead of the stepping motor, the support can be provided with several wave-guides of different lengths distributed at equal angular intervals around the circumference, which successively transmit the partial waves detected to the same detector.

Patent DE-3537519-A1 (DE)
Title: Safety belt arrangement in a vehicle
Inventor: HEUBERGER JUERGEN
IPC: B60R22/24
Filed: 1985-10-22
Abstract: A safety belt arrangement in a car is proposed, in the case of which arrangement a three-point belt is provided with an advancing arm which is pivotable about an approximately horizontal shaft on the vehicle, engages with a carrier on the eye, which is provided with a lock, of the belt and can be pivoted from a rest position into an advancing position, which pulls the belt forwards, and back again. The advancing arm is held in the drag bearing so as to be displaceable with respect to the drag bearing in the direction of the arm. The relative displacement of the advancing arm is controlled in such a way that in its rest position it extends essentially vertically in the centre pillar of the vehicle and in the advancing position is pushed forwards out of the centre pillar and extends approximately horizontally.
Patent DE-3538532-A1 (DE)
Title: 4-cylinder power unit without connecting rods
Inventor: STRACH LOTHAR
IPC: F01B9/00
Filed: 1985-10-30
Abstract: In engines with pistons moved by the force of a gas to perform rectilinear and oscillating movements where the intention is to obtain a torque, the object is to be achieved of forming a positive kinematics for converting the force of the gas into a rotational movement. Examples of applications are steam engines, Stirling engines, spark ignition and diesel engines. In these the gas force is converted into a torque by means of pistons, piston guidance, piston pins, connecting rods and crankshaft. The disadvantage in this is the piston lateral thrust, maximum at the highest piston speed, the slightly oscillating movement in the piston pin bearing, and the cost of constructing a rigid crankshaft in a 4-cylinder arrangement. In the present invention all 4 connecting rods are dispensed with; the crankshaft is very rigid and has only 2 free crank pins; the bearings in the pistons rotate evenly and due to the double piston the displacement losses of existing power units are avoided.
Patent DE-3540242-A1 (DE)
Title: Warm air-heated diesel fuel filter
Inventor: ROEHNER ERNST
IPC: F02M37/22
Filed: 1985-11-13
Abstract: In order to counteract the gelling of diesel fuel under extremely cold conditions, the invention provides that a heating coil which is spirally embedded in a hollow body and is, for example, insulated with glass fibre or silicone material and is heated by means of the car battery, is pushed over the diesel fuel filter, the annular air gap between the filter and the heating coil thus being heated with warm air to a temperature of up to 50 DEG C. For example, in place of the heating coil a flat tubular heating body can be employed, which is also heated with 12 volt and which, like the heating coil, warms the air between the filter and the hollow body to a temperature of up to 50 DEG C and thereby prevents the gelling-up of the diesel fuel filter. Under extremely cold conditions, this warm air heating can also be left switched on overnight, since this battery heating only requires very few Watts for its heating action.
Patent DE-3541594-A1 (DE)
Title: Apparatus for feeding a processing device for flexible, flat products, in particular printed products
Inventor: KELLER ALEX
IPC: B65H31/06
Filed: 1985-11-25
Abstract: The printed sheets (12) lying in the form of a horizontal stack (11) on two conveying chains (4) which are driven so as to circulate are conveyed against the holding-back plate (13), serving as a stop, of a feeder (2). Laterally above the conveying chains (4) there are arranged two toothed belts (16, 17) which are driven so as to circulate and laterally define a conveying channel (21). During the advance, the toothed belts (16, 17) hold the printed sheets (12) in their mutual position within the loose stack (11). The distance (a) between the strands (16a, 17a), facing one another, of the toothed belts (16, 17) is smaller than the width (b) of the printed sheets (12) or of the stack (11). The toothed belts (16, 17) and thus also the conveying channel (21) terminate at a distance (c) before the holding-back plate (13). As soon as the printed sheets (12) held curved by the toothed belts (16, 17) leave the conveying channel (21), the bent-back lateral edges (12a, 12b), as a result of the inherent elasticity of the printed sheets (12), return to their original position. In the process, the printed sheets (12) are in each case raised from the following printed sheet. The printed sheets (12) are conveyed in loosened formation towards the holding-back plate (13), so that a reliable take-off of individual printed sheets (12) from the stack (11) is ensured. <IMAGE>

Title: Device for destroying information on ink-ribbon cartridges, correction ribbons and similar information carriers
Inventor: HEIMBACH NORBERT
IPC: B41J35/38
Filed: 1986-10-16
Abstract: In order to prevent the later reading of used ink-ribbon cartridges which are used in many typewriters in the field of office technology, the ink ribbon is divided in its longitudinal direction into two or more strips by one or more knives. The number of knives and thus also the number of strips depends on the desired degree of destruction security. The individual strips are wound onto separate rollers which are driven jointly by an electric motor. To increase security, they can be fed separately to the office waste. Due to its small dimensions, there is room for the device even in a small office, as a result of which the destruction of information at the site of its production can be guaranteed.

Title: Method and circuit for beam current control
Inventor: KAUFMANN GERHARD
IPC: H04N5/228
Filed: 1987-03-06
Abstract: A method and a circuit for beam current control is proposed, simultaneously permitting overexposure effects in television pick-up tubes to be suppressed. The basic beam current of the pick-up tube for sensing a predetermined exposure of the signal electrode is permanently set here by the potential applied to the control electrode of the pick-up tube. In order to sense overexposures, a supplementary current (IABC) which is dependent on the video signal is superimposed on the cathode current (IK) which produces the basic beam current at a constant cathode potential (UO).
