Title: Circuit arrangement for telecommunication switching networks, preferably telephone switching networks, consisting of exchanges
Inventor: PEITZ ALBERT
IPC: H04W92/02
Filed: 1991-03-18
Abstract: Abstract Circuit arrangement for telecommunication switching networks preferably telephone switching networks, consisting of exchanges, in which mobile subscribers (MT1-MT9) each have access to an exchange  (SC)  through radio channels  (F1-F9)  and stationary subscribers  (STa-STo)  each have access to an exchange  (SC) through cable channels  (K1,K2),  an individual identification being assigned to each mobile subscriber.  Both the mobile and the stationary subscribers (MT1-MT9; STa-STo) are each assigned an individual identification with which the subscriber answers (identification signal) and is thereby identified and localized by the exchange (SC).  The exchange (SC) then assigns a pair of communication channels to the subscriber (MT1-MT9) to establish a connection between the subscriber and the exchange (SC) or vice versa.  The mobile and stationary subscribers have access to the same  exchanges  (SC)  and  the  accesses  of  the  stationary subscribers (STa-STo) pass through broad-band cables (K1, K2), preferably  glass  fibre  cables,  which  run  directly  to  the subscribers.  The cables extend over the entire distance between the  exchanges  (SC)  and  the  stationary  subscribes  without intermediate sub-exchanges and individual wire connections, and the  same  signalization   (identification  signal),   channel allocation (pair of communication channels) and news transmission as between the exchange (SC) and the mobile subscribers (MT1-MT9) connected to it is carried out through the cables so that each subscriber, whether mobile or stationary, is reached from each exchange  (SC)  in the same manner through a through pair of continuous communication channels. To reach all subscribers, the number of pairs of communication channels provided is no greater than that necessary for the expected volume of traffic in the corresponding region.

Title: Method of weaving belt material
Inventor: REITER ERICH
IPC: D03D47/02
Filed: 1991-03-08
Abstract: Process for weaving a ribbon on a needle ribbon-weaving machine with two weft needles (26, 28) which work in opposite directions.  In one embodiment of a process for manufacturing a ribbon, a middle part (1) is woven from a weft multithread and a weft monothread (12, 10), while two edge parts (5, 6) are woven from a single weft multithread (12). The ribbon has high transverse strength but the edges are soft. A main shed (39) for both weft needles (26, 28) is formed from the warp threads (3) of the middle part (1). A  partial traverse shed (38), through which only the weft needle (28) for the multithread (12) is inserted, is formed for each of the two edge parts (5, 6). The heads (14) of weft loops which are interlaced with the edge part weft threads (8) are secured by a row of stitches (18) located at the outer side of the edge part.  The heads (24) of weft loops which are interlaced only with the middle part weft threads (3) are secured by a row of stitches (20) located at the outer edge of the middle part (1) and on the inner edge of the adjacent edge part (5). In a second embodiment for weaving a ribbon with two weft needles working in opposite directions, the ribbon is woven by inserting both weft needles into a common shed. The heads (60, 66) of the weft loops inserted in opposite directions are secured by two rows of stitches (62, 68) each formed from an auxiliary thread and located at the two outer edges of the ribbon. This ribbon has no edge parts but is absolutely symmetrical, and it has outer edges which are protected by the two rows of stitches (62, 68) and are soft.

Inventor: GOSSEL CHRISTIAN
IPC: F26B23/00
Filed: 1993-03-11
Abstract: ABSTRACT            The invention relates to a device for drying and/or concentrating sludges composed primarily of water, sand or similar inorganic solids and non-volatile hydrocarbons, or of individual constituents of the sludge or of combinations of individual constituents of the sludge.            The fields of application for these vaporizers/dryers are highly varied, as evaporation and drying constitute a basic principle of the processing technology (unit operation).  Any substances which exhibit little or no delays in boiling point during concentration and/or evaporation, which do not form hard crystalline films, and which remain somewhat fluid or spreadable, are suitable.            The device in accordance with the invention, which combines the principle of vapour compression with a mechanical spreading and scraping device, makes it possible to dry and/or evaporate sludges with a high proportion of very fine grains under economically acceptable conditions, because the evaporation heat produced by the vapour compression can be repeatedly reused.

Abstract: The cost of a telephone toll call is shared by arranging the billing system of the telephone toll carrier to permit sharing of  the  period  cost  for  at least  one indivisible time period of a toll call. Accordingly, at least a portion of the period cost associated with at least one of the indivisible time periods of a toll call is assigned to both the terminating and originating subscribers, so that each subscriber to the toll call is billed for a portion of the total basic cost incurred for each of those indivisible periods of time over which it is agreed that the period costs will be shared. Anauthorization signal, indicating that the subscriber who would not have shared in the period costs for any indivisible period if the call had the call been placed as in the prior art--typically the terminating subscriber--agrees to accept his share of the period costs, may be required before any period cost sharing periods can occur.
