Title: Electrical safety device for a stacker vehicle which can be moved guided by drawbar
Inventor: GREGER GERHARD
IPC: B60K28/00
Filed: 1984-08-04
Abstract: In an electrical safety device for a stacker vehicle which can be moved guided by drawbar and has a drive motor and a travel switch, with which said stacker vehicle can be controlled to move forwards or backwards, the function of the emergency switch is disabled when the stacker vehicle is stationary. The function of the emergency switch is to be enabled when the stacker vehicle moves backwards. In order to achieve this, on a part of the stacker vehicle which is involved in rotation during the travel movement of the stacker vehicle a sensing device is arranged which detects the rotational movement of the part which is involved in rotation and outputs a corresponding electrical signal to an evaluation circuit. A blocking circuit which disables the emergency switch when the part involved in rotation is stationary and enables the emergency switch when the part involved in rotation experiences a rotational movement is controlled by the evaluation circuit.

Patent DE-3429457-A1 (DE)
Inventor: PATZAK GUENTHER
IPC: H04Q3/72
Filed: 1984-08-10
Abstract: Method for the identification of calling or called terminals connected by an external transmission bus enabling, upon the implementation or establishment of a connection, the transmission of a data signal flow between the calling terminal and a called terminal. The disadvantages of this type of calling and called terminals is to make impossible their identification once the connection is established. It is therefore proposed to couple the external transmission bus intended to the identification of the calling or called terminal (1) to an auxiliary device (5) during a predetermined time duration  DELTA t by means of a coupling device (4). Said auxiliary device (5) enables to send an identification signal ID by the external transmission bus (2).

Title: Device with solar cells for supplying hearing aids with electrical power
Inventor: GRAF PAUL
IPC: A44C15/00
Filed: 1985-01-17
Abstract: Hearing aids have previously been operated with button-cell NC batteries. To make the user independent of the batteries, my hearing aids are supplied with power from solar cells. These have the property of converting sunlight, daylight or artificial light into electrical current. The user can thus hear at any time and without restrictions, without having to worry that his hearing aid will stop because of a power failure. Batteries, in contrast, only have an operating life of a few hours when they must be exchanged against new ones. Batteries can additionally be used in alternation, an interruptor switching off the plug connection to the solar-cell part. The solar-cell holder can have different shape, as a square, flat rectangle, circle, semicircular column or hemisphere. It can also be designed as an ornament in the form of a blossom, cascade, clip or hair ornament, for the purposes of camouflage. The stranded electrical connecting wire can also be formed in the form of a chain. The battery located in the device is automatically switched off by the plug connection of the solar part. At home, the solar part can be placed under a desk lamp and will even work with a candle. The advantage is obvious. The listener is independent of batteries in developing countries, on journeys at sea, on land and in the air. My prototype generates current at up to 3.4 volts so that even smaller models ...

Title: Torsional vibration damper for the path of the driving torque in a motor vehicle
Inventor: DREXL HANS-JUERGEN DR
IPC: F16F15/131
Filed: 1985-08-13
Abstract: The torsional vibration damper for motor vehicles comprises two main parts which are rotatable relative to one another about a common axis of rotation through a limited angle of rotation, at least one spring coupling the two main parts to one another in torsionally elastic fashion, and a frictional damping device that can be acted upon during the relative rotation of the main parts. Arranged in the torque transmission path of the frictional damping device is an idle-motion device (107, 117, 119) which connects the frictional damping device to the first main part (1a) via a driver part (79a) which can move with limited play about the common axis of rotation relative to a first (1a) of the two main parts. The idle-motion device has a travel-limiting part (117, 119) which can be moved relative to the first main part (1a) and the driver part (79a) and, as a function of its position relative to the first main part (1a), determines the amount of play of the driver part (79a). A centrifugal weight (83a) moveable transversely to the axis of rotation and preloaded resiliently towards the axis of rotation controls the position of the travel-limiting part (117, 119) as a function of the rotational speed. The travel-limiting part (117, 119) is preferably controlled in such a way that the play of the driver part (79a) is at a maximum in the idle speed range of the engine and decreases in the direction of lower and higher engine speeds. In this way, the frictional torque can be better [...] to the requirements when idling, on the one hand, and when starting and stopping the engine as well as in ...

Title: Plucking finger
Inventor: KOLTHOFF DIETER
IPC: A22C21/02
Filed: 1985-10-22
Abstract: A plucking finger made of an elastomer material having a profiled finger enclosure to permit frictional engagement with the poultry carcase and having a foot which is to be releasably inserted by its end enlargement into a plucking plate which can be driven in a rotary manner, is formed by an inner channel which extends in the longitudinal direction of the finger in order in particular to increase the service life, but also in order to permit a wider choice of elastomer materials and to achieve improved adjustability of the inherent rigidity and the inherent curvature under working loads. This makes it possible to reduce flexing work owing to the fact that the hollow cross-section can be deformed more easily, but also to reduce heat stress by means of internal ventilation, and to modify the way in which rigidity changes longitudinally and also transversely.

Title: SO2 scrubbing downstream of combustion plants with crude gypsum as the end product
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/34
Filed: 1985-11-22
Abstract: It known to scrub out SO2 from the dirty gas stream downstream of fossil-fuelled combustion plants by means of an aqueous solution enriched with lime. The aim is to free from gaseous pollutants the dirty gas loaded with SO2 and/or NOx and other acidic constituents and to achieve gypsum as the end product. Since coal having a very high chlorine content interferes with the actual scrubbing process for scrubbing out SO2 and/or NOx, it is known to provide a so-called prescrubber in order to scrub out the acidic constituents HCl, HF, etc. before the actual SO2 and/or NOx scrubbing. The salt load produced in the prescrubber generally must not be transferred to the rivers or the outfall but must be concentrated by evaporation and supplied to other applications or else to a special landfill. The gypsum produced must frequently be furnished with an additional chloride addition or, depending on the chloride content loading, be fed to a further processing. In order to further improve the purification process overall, according to the invention it is proposed that the crude gas scrubbing is carried out in a prescrubber (2) which is operated at an acidic pH in which chlorides are scrubbed out of the dirty gas stream, and downstream of a scrubber (2) is provided a secondary scrubber (3) in which SO2 and/or NOx are scrubbed, the absorption media for scrubbing SO2 and NOx being fed to the secondary scrubber (3) and the ...
