Title: Routing translator
IPC: H04Q3/545
Filed: 1966-05-13
Abstract: 1,119,595. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 13 May, 1966 [17 May, 1965], No. 21295/66. Heading H4K. In an interexchange system in which each exchange carries a record of the idle/busy conditions of all interexchange trunk routes in the system, each exchange has a routing arrangement comprising a matrix, Fig. 3, each horizontal of which represents a route from the exchange to a distant exchange in that it is employed to mark a particular set of verticals 1 through 5 to N, each of which verticals represents an interexchange trunk route in the system and each horizontal being coupled to those verticals pertinent to the trunks comprising the route represented. A register 61, given the identity of the wanted exchange, applies to a translator 62 which by marking a lead such as 70 marks all horizontals (such as 1<SP>1</SP> to 4<SP>1</SP>) representing all possible routes to the wanted exchange. Those interexchange trunk routes in the system that are blocked are indicated by earth connected to the corresponding matrix vertical by a relay set 102 controlled from a so - called network computer which keeps acquainted with network conditions after the manner described in Specification 1,079,280. From out of the horizontals that are not blocked by an earth a so-called pick chain 115 allots a preferred one according to an order of priority which can be altered according to circumstance as with busy-override. A relay from the set 89-93 is energized to indicate the route chosen to a decoding matrix, Fig. 4, from which the corresponding routing digits can be derived. Contacts of the energized one of relays 89-93, such as contacts 91, mark a horizontal of the decoding matrix to indicate in 2 out of 5 code, the groups of digits required sequentially by the register-sender to set up the route. The register applies sequentially to the groups of verticals of the matrix for successive digit groups and when it reaches a group in which a vertical LA is coupled to the horizontal by a diode such as 145 it recognises this as the last group required. Should two routes be chosen simultaneously two sets of contacts such as 91 will be operated and a diode in the chain 127 will conduct to signal the fault to the register by way of terminal 126. Class of service restrictions are provided by relays such as 109, 110, Fig. 3. Routes barred to a call are indicated by earth on the horizontals representing the routes. As shown, relay 109 bars all routes. If, while the register sender is obtaining routing digits from the decoding matrix, one of the trunk routes in the path is signalled as blocked, the originally selected route is abandoned and a second choice is made.

Abstract: 441,619. Guiding loom warp threads. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and JABOULEY, J., c/o British Celanese, Ltd., Spondon, near Derby. July 23, 1934, No. 21460. [Class 142 (ii)] Threads from adjacent beams 6, 7 are distributed over a common space in the vicinity of the adjacent ends of the beams which would otherwise be occupied only by separate sets of threads proceeding from separate beams, whereby warp streakiness at the point of union is eliminated. Thus, in a circular loom, wherein the warp threads from beams 6, 7 are leased into sheets, 19, 20 by circular lease rods 15 on brackets 16 suspended from a ring 17 supported by a spider 18 on the central shaft 14, the warp threads are guided by a thread spacing comb 24, reed or perforated plate in such a manner that say 10 to 15 threads of the outer sheets 19 are crossed as shown. Unevenness in warp tension at the ends of beam is thus distributed over a greater width of fabric. The remaining threads pass normally to the fabric. The normally proceeding threads comprising the ends of the inner sheet 20 are omitted from Fig. 1. Instead of the threads being crossed in simple alternation as described, two adjacent threads from one beam end may alternate with two from the adjacent beam and so on. Some threads from one beam may be distributed over an adjacent beam and others over a further adjacent beam. The invention may be applied also to rectilinear such as wide sheeting looms. The comb 24 may be formed in sections 26. The warps may consist of fine smooth natural or artificial silk threads. Specification 413,376 is referred to. The Provisional Specification also refers to Specification 396,756.
