Title: Improvements in or relating to communication circuit arrangements
IPC: H04Q3/00
Filed: 1961-08-28
Abstract: 944,736. Automatic exchange systems. SIEMENS & HALSKE A.G. Aug. 28, 1961 [Aug. 26, 1960], No. 30908/61. Heading H4K. In a multi-stage switching network of coordinate switches having a path-search network which is used to find free intermediate links to form parts of a wanted communication path between an inlet and an outlet, wherein the wires of the path-search network are individually associated with the intermediate links (there being only one path-search wire for each link) and are connected to each other at so-called metering junctions corresponding to the switches of the switching stages so as to permit the selection of portions of the path-search network corresponding to free links which form the desired communication path, a marking potential is applied to at least one input of the pathsearch network and thence is extended to at least one output thereof, where it is examined, the extension of this potential being effected in succession at the marking junctions included in the search wires, and the path sections thus selected being maintained in a condition suitable for transmission. The switching network consists of four stages of cross-bar, cross-coil or relay switches A . . . D arranged as shown in Fig. 1. Fig. 2 illustrates a typical speech-path through the network and Fig. 3 the path-search wires and test arrangements. There is a path-search wire corresponding to each inter-stage trunk and those wires corresponding to trunks to or from the same switch, e.g. B1 are commoned at the so-called marking junctions such as fB1. When a connection is to be set up from an inlet j of switch A1 to outlet 1 of switch Dn, the contact tlj of the inlet is closed thus applying a positive potential to the search wires associated with the inter-stage links from switch A1. Means not shown effects closure of contact z11 associated with the wanted outlet. Each path-search wire includes a contact such as bab11 which is closed when the associated trunk is free, so that when the contacts of the test equipments KVB, KVC, KVD and PKVD are closed the device P will respond if a free path exists. The contacts of KVB are then all opened (P relapses) and are then closed again in succession in a random sequence, the response of P when a path is closed stopping KVB. Alternatively the contacts of KVB may be opened in succession until P relapses, whereupon the contact which was last opened is closed again. The contacts of KVC are then operated in like manner to those of KVB. The operated contacts of KVB and KVC select the wanted path, since they determine the B and C marking junctions in the path, and the switches are then operated to complete the corresponding speech path. If desired a plurality of outlets may be considered, the corresponding z contacts (not shown) being closed and equipments KVD and PKVD being operated to choose the outlet to be used. Specifications 897,676 and 897,677 are referred to.

Generating by hot coke.-Consists of apparatus for cooling coke by means of inert gases flowing in a closed cycle and arranged to heat a steamgenerator. Two forms are described. In one, Fig. 1, a tilting platform B, running along the front of the battery, receives the hot coke and delivers it to the steam plant at the end of the battery. This comprises the generator D and feed-water heater E, E<1> arranged above a hotcoke chamber F2 through which the coke is traversed in receptacles G, the receptacle just filled being positioned beneath the generator while the two partially cooled ones are beneath the feed heaters. The receptacles when within the chamber F2 are connected to the delivery of a fan, the inlet of which is connected to the uptakes of the generator and feed heaters, so that, after the preliminary combustion on connecting up, inert gases only are circulated. On the entry of a newly filled receptacle, that at the other end, now cooled, is pushed out, discharged, and returned to the receiving end. In a modification, the boiler runs in front of the battery and the coke is discharged direct into a chamber below it, where it is cooled partly by inert gas circulation as before and partly by water jackets. The steam produced drives a turbo-generator connected to the network of the system by sliding contacts, and the condenser circulation through a stationary cooling tower is maintained by means of connexions to open troughs running in front of the battery. The coke is discharged either by the entry of the fresh charge or by a conveyer forming the bottom of the receptacle.
