Patent DE-3112145-A1 (DE)
Title: Adhesion device for cross-country skis
Inventor: LESSAU KURT
IPC: A63C9/20
Filed: 1981-03-27
Abstract: Cross-country skiing and ski-hiking are increasingly practised by elderly people who lack the physical requirements to cope with ascents and descents reliably and without falling. The subject matter of this proposal is a device which, under loading conditions, allows cylindrical hard metal or plastic pins to protrude 5 to 10 mm from the plane of the running surface of the ski so that better adhesion between the ski and the track is achieved than with the usual scaled running surfaces. Since the pins are flush with the lower edge of the ski running surface in the gliding position (when the ski is pulled along and when the ski is loaded by the heels), the slidability of the skis fitted with adhesion devices is greater than the slidability of skis with scales or scale-type profiles since the profiling of the ski running surface is not required in conjunction with the adhesion devices explained here. By means of an arresting device, the adhesion device can be fixed both in the starting position (for flat routes) and in the position with protruding pins (for ascents and descents). <IMAGE>

Title: Application and metering device, in particular for double belt presses
IPC: B05C1/08
Filed: 1981-04-10
Abstract: The invention relates to an application and metering device, in particular for double belt presses, for coating continuously moving webs of paper, textile or mineral fibres and similar web-shaped materials with liquid or dissolved thermosetting binders for producing single-layer and multilayer laminates, which is characterised in that it consists of an engraved, heatable metering roll (1) which is rotatably mounted and driven, right-handedly or left-handedly, with controllable circumferential speed about a pivot axis (2). The metering roll (1) bears against a heatable support roll (3), which can be driven in the web advance direction and has a surface which is made elastic by means of, for example, rubber coating (4), in such a manner that, together with the material web (5) looping over the two rolls (2) and (3) and end plates (8) held fixed by pot magnets (6) in the two end faces (7) of the metering roll (1), it forms a channel-shaped feed space (9). Via a proximity sensor (10), the feed space (9) can receive a level-controllable volume of binder in such a manner that, from this supply, to be controlled by the consumption of the material web running through and to be re-filled by metering pumps, a metered volume of binder, determinable by the parameters web velocity, level, binder viscosity and binder temperature, metering roll speed and direction and metering roll engraving depth, per web unit area can be applied to the moving material web. Using the device according to the invention, the fibre webs to be processed can be impregnated rapidly and smoothly and can be continuously fed to the reaction zone so that escape of volatile solvents and any drying is virtually eliminated. <IMAGE>

Title: Production of cellulose from wood or other lignocellulose-containing plants by microbiological degradation of the lignocellulose on mobile vehicles
Inventor: EISENSTEIN ALBIN DR ING
IPC: F02B3/06
Filed: 1981-07-16
Abstract: A process is described for the biological production of cellulose on mobile vehicles, mainly ships. As can already be seen from the main application P 3110117.8, this biological process is based on the use of white rot fungi (Pleurotus ostreatus) and extracellular enzymes. The cultures required for breeding the white rot fungi and for producing the enzymes are also accommodated on the ship. The necessity for providing arrangements for the protection of the environment ceases to apply since the process does not entail pollution of the environment. The heat required for the microbiological degradation is obtained from the waste steam (exhaust steam) of the ship's turbine or from the waste heat of the cooling water of the diesel or gas engines of the driving motors.

Title: Method for setting up connections in voice and data transmitting digital telecommunications networks and switching devices
Inventor: THEIS HARALD DIPL ING
IPC: H04Q11/04
Filed: 1982-01-30
Abstract: The method for setting up connections in voice and data transmitting digital telecommunications networks and switching devices provides that a check is first carried out via a signalling channel to ascertain whether a station to be called is free or busy, and that the connection is immediately set up in a forward direction only if the station is free. If the station is busy, information identifying the calling station is transmitted to the station to be called where it is again temporarily stored. As soon as the station to be called is free, a backward connection is set up from the station to be called to the calling station, with the result that the connection paths or channels provided for the message exchange are occupied for real connections only and are not seized for waiting connections.

Patent DE-3222177-A1 (DE)
Title: Clutch system for driving and braking conveyor rolls
Inventor: SCHINDELE REINHARD
IPC: B65G13/075
Filed: 1982-06-12
Abstract: The frictional clutches on each conveyor roll of an accumulator roller conveyor, operating in a pressureless manner, consist of the roller end plate (8), the frictional lining (9) and the driven chain wheel (11). A flat tube (15), closed at both ends, within the side rail (1, 2) of the roller conveyor presses when full a pressure strip (13) against the chain wheel (11) in order to provide the frictional connection for the drive of the roll. Evacuation of the tube effects the removal of the frictional connection. The length of the tube determines the number of rolls to be driven and thus the length of the accumulator space. A braking function of the rolls is achieved when the tube on the opposite of the roller conveyor and the pressure strip (27), acting as a static brake surface, is pushed against the roller end plates. The alternate filling and evacuation of the tubes by means of suitable valves and the logical, expedient connection of these functions is no problem for the person skilled in the art. The signals for switching over the valves can be obtained in various ways. For example also by the operation of a limit switch (29) by means of a conveyor roll. <IMAGE>
