Abstract: A polygon sort engine (100) including first and second apparatus (120, 122) for sorting. The first apparatus (120) for sorting receives planar, externally convex polygon vertices (102) from an external polygon tiling engine. This includes points and lines. The state machine (112) on the second apparatus (122) for sorting interfaces with the polygon tiling engine and a raster engine in a graphics pipeline. It provides a control signal which determines when the first apparatus for sorting will receive the next polygon. The second sorting appartus also controls whether the polygon is stored in the PING or PONG memory (104). For example, as the state machine (112) is controlling the sorting of the current polygon into the PING RAM, the state machine will also be controlling the loading of the previous vertices and the PONG RAM into the raster engine.

Abstract: The drawbar 12 of a trailer coupling is clamped by a clamping nut 38 in a drawbar bearing 22. In order to secure against loss of the clamping nut 38, a securing washer 74 is provided at a distance from the correctly tightened clamping nut 38. If the clamping nut 38 should unexpectedly come loose, the drawbar 12 in the drawbar bearing 22 becomes wobble-free at the latest when the clamping nut 38 reaches the securing washer 74. Then, it can be determined from the driving behaviour and/or by means of a wobble attempt during inspection whether the clamping nut 38 has left its correct position and this can be remedied. <IMAGE>

Abstract: Carboxyl-containing graft polymers in which vinyl carboxylates and optionally further ethylenically unsaturated monomers are polymerically grafted onto carboxyl-containing polyurethane graft bases by means of free radical-initiated graft polymerisation, and hydrolysis (saponification) products and salts of these carboxyl-containing graft polymers, can be obtained by grafting vinyl carboxylates having 3 to 20 carbon atoms and optionally further ethylenically unsaturated, polymerisable monomers, which are optionally copolymerisable, preferably in amounts of from 10 to 95% by weight, based on the carboxyl-containing graft polymer, onto a carboxyl-containing polyurethane graft base containing at least 2 urethane groups in the molecule, by means of free radical-initiated graft polymerisation, and optionally subsequently saponifying all or some of the vinyl ester units and any further saponifiable monomer units in the grafted-on polymer radicals of the graft polymers by hydrolysis and/or alcoholysis or converting the carboxyl groups to salts. Preferred vinyl esters to be grafted on are vinyl acetate and/or vinyl propionate and optionally vinyl versatate. The graft polymerisation is preferably carried out in solution or in bulk. Unsaponified graft polymers are suitable, inter alia, as adhesives, in particular as hot-melt adhesives, and, in their water-soluble or water-dispersible salt forms, as dispersants. Fully or partially saponified graft polymers are suitable, inter alia, for the production of films (sheeting). Depending on the carboxyl group content of the polyurethane graft base, the degree of grafting, the degree of hydrolysis and the nature of the grafted monomers, the graft polymers, compared with polyvinyl alcohol, have significantly improved solubilities in aqueous-alkaline media and reduced melting points, so that they are advantageously suitable for the production of pressed and extruded films under mild temperature conditions without the concomitant use of organic plasticisers. Saponified graft polymers are furthermore suitable, inter alia, as adhesives, as dispersants in aqueous-alkaline media and as sizes and lubricating agents in textile processing.

Abstract: An improved data link control device for use in high speed data communication applications, for instance primary rate ISDN applications, includes facilities for dynamic HyperChannel mapping. In such mapping, plural communication channels which ordinarily could be used for separate communication applications are associated as a HyperChannel group, and data communication is carried out concurrently over all channels of the group so as to advantageously utilise the aggregate bandwidth of the group. The present mapping facilities comprise means for designating one channel in each mapped group as a reference channel for the group, means for associating all other channels in the group to the respective reference channel, means for storing control information relative to the respective reference channel, and means responsive to the control information for conducting a data communication operation through all of the grouped channels including the reference channel as if all of said channels constituted a single extended channel having a bandwidth equal to that of the reference channel multiplied by the number of channels in the group.

Abstract: A method for servicing a mount request in an automated storage library (1) in which all of the peripheral storage devices (4) therein are occupied and which permits an active data storage medium to be temporarily demounted and subsequently remounted in any subsequently available peripheral storage device is disclosed. To service a mount request requiring that a data storage medium be demounted, the access information for the data storage medium to be demounted is first retained. After demounting and servicing of the mount request, the retained access information is used to permit remounting of the previously mounted data storage medium in any subsequently available peripheral storage device, thereby minimizing the risk of delay in remounting. The method also allows for optional parameters to prevent temporary demounting in an automated storage library, or to prevent temporary demounting of particular data storage media. The method allows access to more data storage media than there are peripheral storage devices by temporarily demounting the least recently used data storage media.

Abstract: A versatile production system produces different kinds of products in small quantities. 
     The system includes production lines for assembling parts into different kinds of products, testing the assembled products, and conveying the products that have passed the tests to a collective packing terminal. 
     Each production line has a pallet feeder for feeding pallets one by one to the start of the production line. 
     Each production line has a bypass structure. The bypass structure includes a first switcher (1), a a main line (2), a bypass line (3), and a second switcher (4). 
     The first switcher (1) determines whether or not a product conveyed on a pallet must be repaired or tested, and according to the determination, switches the pallet and product from the production line to one of the main and bypass lines. 
     The main line (2) receives pallets and products switched thereto by the first switcher (1) and conveys same. The bypass line (3) receives pallets and products switched thereto by the first switcher (1) and conveys them slower than the main line (2), or temporarily stops them. 
     The second switcher (4) switches pallets and products from the main and bypass lines to the production line. 
     The collective packing system packs products conveyed on pallets and returns the emptied pallets to the respective production lines.
