Patent DE-3128526-A1 (DE)
Title: Current-limiting fast-action switch
Inventor: TAYEFEH-EMAMVERDI MOHAMMAD DIP
IPC: H01H77/10
Filed: 1981-07-18
Abstract: In the case of a current-limiting fast-action switch having at least one main contact and one erosion contact and having a device for protecting a contact force (FKH, FKA) on the contact elements (3, 4, 6, 7, 15, 17) of the main contact and the erosion contact, the current which is to be switched off is commutated from the main contact onto the erosion contact, above a predetermined limiting current value. In order in this case to make possible a short commutation time and fast separation of the erosion contacts (17, 23), it is proposed to construct the main contact as a drive and to arrange it in such a manner that it opens while the erosion contact is switching off. In this case, it is advantageous to connect the main contact elements (3, 4, 6, 7) rigidly to current conductors (2, 8) which are arranged approximately parallel to one another and through which the switching-off current flows in the same direction, and at the same time to couple at least one of the main contact elements (4, 6) in a force-fitting manner to a striker pin (11). Such a switch is suitable for use as a high-power switch for direct currents and alternating currents having high rated intensities. <IMAGE>

Patent DE-3139119-A1 (DE)
Title: Concave running surface for skis
Inventor: OBERHOFER FRANZ
IPC: A63C5/04
Filed: 1981-10-01
Abstract: The purpose of generally increasing safety in the sport of skiing is served by a new shape of the running surfaces of the skis. Instead of the currently customary central groove along the skis, a concave or similarly shaped construction of the ski cross-section is provided over the entire width and length of the ski without the outer shape and inner construction of the common types of skis for the usual branches of the sport of skiing and branches of use needing to be changed. In addition to improved track adherence during sliding, this concave shape of the running surfaces guarantees a far more effective grip in all skiing-related movements, whether these are in cross-country or downhill skiing or ski jumping, on all types of snow (icy pistes and cross-country tracks) - and on any terrain. The same effect cannot be achieved with the currently customary means (steel edges and the like) on flat running surfaces. The attached drawing shows ski cross-sections with concave surfaces. <IMAGE>

Patent DE-3202854-A1 (DE)
Title: Electrically conductive hose line
Inventor: BRAUN ALFRED
IPC: F16L11/127
Filed: 1982-01-29
Abstract: A hose line, in particular for conveying combustible or explosive media, consists of elastomer or polymer material or their mixtures and has a pale or coloured inner layer and, if appropriate, bright or coloured intermediate or covering layers, at least part of the hose cross-section consisting of electrically conductive elastomer or polymer material, which extends at least in partial regions up to the inner surface of the inner layer. To ensure that the inner layer is not significantly disturbed in its function or weakened in strength by the electrically conductive material, which generally contains carbon black, reaching as far as the surface of the said inner layer, the partial regions in which the electrically conductive elastomer or polymer material lies in the inner surface in the inner layer are essentially punctiform. By this measure, the region of the electrically conductive material coming into connection with the conveyed medium is reduced to a minimum and the inner layer of the hose line is interrupted by this material only at a few points.

Title: Scrapers for scraper conveyors underground
Inventor: GARTE RUDOLF
IPC: B65G19/24
Filed: 1982-05-11
Abstract: Underground, scraper conveyors are used for removing coal. In this arrangement, the scrapers are screwed onto the round link chains. The scrapers are drop-stamped in one piece and each scraper is different in terms of height and width. This causes a large amount of storage, and high repair costs owing to wear on the guides of the scraper. The invention presents a scraper which is in modular-construction form, the parts comprising a central part, lateral sliding blocks and a bow. The particular advantage is the screw-free design and the favourable slide-type guiding of the modular-construction scraper. The scraper can be used for a number of types of scraper conveyors. <IMAGE>

Title: Multi-delivery spray can with chamber insert
Inventor: DAUBNER GERHART
IPC: B65D83/14
Filed: 1982-08-24
Abstract: The container described above allows different liquid or dry substances to be sprayed from a plurality of fixed chambers selectively individually or also simultaneously. In the case of simultaneous spraying of different consistencies, the substances to be conveyed are stored in chambers of different sizes, mixed with the propellant gas, in accordance with their density or their proportional effectiveness. Rising pipe diameters and nozzles of different sizes ensure that the chambers are emptied simultaneously. Calculable constant pressure ratios inside the container are guaranteed by the rigid chamber walls. Spraying media which are aggressive relative to one another are only mixed together in the spray jet. Filling is effective selectively via the valves, via openings in the bottom which can be closed by stoppers, or via needle valves. With reference to P 3142205.5, it is possible to store the spray substances inside the container separately from the propellant and to spray them individually or simultaneously as pure active ingredients. Possible applications of this design result in all techniques which aim to deliver substances from a container by means of pressure.

Title: Pivotable lens tube for miniature camera and half-plate camera systems
Inventor: FIEGE THOMAS
IPC: G03B5/06
Filed: 1983-02-08
Abstract: The pivotable lens tube connects the lens to the camera housing, doing so as an integrated component or as an attachment. It consists of a tube section, which is cut obliquely relative to the longitudinal axis and can be recombined in such a way that both parts can be rotated with respect to one another in the sectional plane. The result of this is to enable the lens to be pivoted out of the normal optical axis and thus to influence the zone of the depth of field in the imaging. In connection with a device which permits the lens to be displaced parallel to the image plane, a device is produced which permits functions of mechanically and structurally complicated studio cameras to be transferred in a convenient and economic way to miniature camera and half-plate camera systems.

Title: Arrangement for magnetic signal recording and reproduction
Inventor: JAEGER KONRAD DIPL PHYS
IPC: G11B5/49
Filed: 1983-02-11
Abstract: The mechanical movement between the magnetic head generating the signal magnetic flux and the magnetic storage layer required in the magnetic recording and reproducing process can be assisted in certain arrangements by a non-mechanical displacement of a magnetically recorded state in the interior of the magnetic head, effected by control magnetic fields. In a particular embodiment of such an arrangement, the harmful coupling between control magnetic flux and signal magnetic flux is to a great extent suppressed. Together with other features concerning the position of the signal windings and their excitation, higher storage densities can be achieved by this embodiment.
