Title: Coke, process for its production and its use for producing synthetic graphite electrodes
Inventor: MIYAZAKI HARUNORI
IPC: C10L9/08
Filed: 1983-10-14
Abstract: Coke for use in the production of synthetic graphite electrodes is described. To produce such a coke, raw coke from coal or petroleum, containing 5 to 12% by weight of volatiles and produced from raw materials having a content of nitrogen compounds, that is to say coal tar and/or coal tar pitch or heavy oil, is calcined. This gives coke in which the nitrogen content has been significantly reduced or nitrogen has been completely eliminated, if the calcination of the raw coke is carried out in the temperature range from 1300 to 1500 DEG C while maintaining a sufficient residence time. Coke having a nitrogen content of less than 3.0% by weight and a content of pores having radii of not more than 5000  ANGSTROM  in a volume fraction of not more than 0.04 cm<3> is obtained by this process. This coke is particularly suitable for producing synthetic graphite electrodes.

Patent DE-3428662-A1 (DE)
Title: Friction clutch
Inventor: BRAUN HELMUT
IPC: F16D13/46
Filed: 1984-08-03
Abstract: The invention relates to a friction clutch, in particular a friction clutch for motor vehicles, having a diaphragm spring which has tongues extending radially inwards, a pressure plate which serves for the release of the clutch being fastenable in the radially inner region of the tongues via a bayonet-like connection and the pressure plate being clamped axially in the process between a relatively large number of actuating tongues, provided on that side of the pressure plate which is situated towards the release direction of the friction clutch, and a relatively small number of retention tongues provided on the side away from the release direction. The object on which the present invention is based is to ensure the holding of the pressure plate on the diaphragm spring in a particularly simple, efficient and economical manner while at the same time improving the operation of the friction clutch. This is achieved by the fact that the retention tongues can be passed through radial cut-outs provided on the outer circumference of the pressure plate and the actuating tongues and the retention tongues are splayed axially by a rotation of the pressure plate relative to the diaphragm spring, with the result that the pressure plate is clamped between these. The points of contact for the actuating and retention tongues with the pressure plate are of spherical design.

Patent DE-3430408-A1 (DE)
Title: Brake pressure retaining device for direct-release air brakes of rail vehicles
Inventor: KUBATH GERHARD
IPC: B60T15/42
Filed: 1984-08-17
Abstract: The brake pressure retaining device for direct-release air brakes of rail vehicles has a retaining valve 4 incorporated into the bleeding duct 2 of a brake cylinder 1. The retaining valve 4 contains a diaphragm valve 10, 13, which is opened in the resting state and can be closed by feeding in a compressed air signal through a line 17. When the retaining valve 4 and hence the diaphragm valve 10, 13 are in the closed state, the bleeding of the brake cylinder 1 is blocked, so that previously initiated braking is maintained even if the direct-release brake control valve 3 is switched over into the release position. Only when the compressed air signal decreases and the retaining valve 4 is thereby opened is release of the brake possible. For the accelerated decrease of a compressed air signal present in the line 17, the retaining valve 4 may be combined with a rapid bleeding valve for the line 17. <IMAGE>

Patent DE-3510784-A1 (DE)
Title: Non-capsizable ship
Inventor: MICHAS MICHAEL
IPC: B63B43/14
Filed: 1985-03-25
Abstract: The present invention "non-capsizable ship" relates to a ship construction whose main body in which the crew or passengers are located is suspended in a pendulous fashion so that it rotates perpendicularly in the direction of the centre of gravity in opposition to the rolling motion. Here, the main body, determining the main water displacement, is closed all round and is rotatably arranged about its longitudinal axis in a stabiliser system. Apart from stabilisation with regard to the said oscillations, further stabilisation of the main body against pitching moments is provided according to the invention among other things by virtue of the fact that the main body is specifically suspended in a special stabiliser. In this arrangement, the stabiliser consists of a support frame revolving at a relatively great distance from the main body and having floating bodies arranged symmetrically on it. These floating bodies here act as an additional, lateral "protective barrier" against external forces such as wind and waves. Here, the outer support frame with the lateral floating bodies assumes a new stable floating position after a rotation of over 90 DEG , in the course of which the floating bodies if need be plunge into and out of the water repeatedly.

Patent DE-3603302-A1 (DE)
Title: Dice bar with writing refill
Inventor: DRIGNATH ROLAND
IPC: G07C15/00
Filed: 1986-02-04
Abstract: The invention is characterized by an apparatus which is composed of a hollow body of various shapes (oval or round shape) for receiving dice inscribed with numbers, letters and the like, or alternatively balls, and a bar-shaped feed channel with an inserted writing refill.   The cup-shaped hollow body, filled for example with a particular predetermined number of dice, makes it possible, after repeated shaking, for dice, for example with numerical or character identification, to pass into a channel whose length is set for a desired number of units, or which is rigid, in order that an evaluation can be read off therefrom. A writing refill (for example, ball-point pen) present at the end of the dice bar then permits this series of numbers or characters to be recorded immediately in a convenient manner. With this basic structure of the dice bar it is possible to see that, for example with the aid of the dice and/or balls located in a channel and optionally provided with a variable identification, any desired playing operations (lottery, football pool, party games, etc.) and identification of persons and articles, place allocations and determination of a sequence of participants in events or competitions, can be implemented or determined.

Patent DE-3608822-A1 (DE)
Title: Guide arrangement for blind shafts
IPC: B66B7/02
Filed: 1986-03-17
Abstract: In blind shafts in underground mining, the guide for the cages is designed in such a way that more or less smooth running is possible. Here, the guide rollers are arranged on the side surfaces of the cage and on the counterweight in such a way that they are each guided in pairs engaging in the same guide rail. Thus a travel way of large volume is made available for a blind shaft with cage and counterweight of correspondingly large dimensions. Both guides only need a total of two guide rails, on which the counterweight required as a rule is therefore also guided. In this arrangement, the brackets of the guide rails are designed in such a way that they can be pushed onto the girders carrying them and can be turned or displaced on these girders in the mounted state. Thus accurate setting of the guide rail is possible as viewed over the height of the shaft so that safe and smooth running both for the cage as such and for its counterweight is guaranteed. <IMAGE>
