In a sectionalized exchange of the type described in Specification 989,336 calls are set up in the normal way by paths across the network from the calling and called terminals on one side of the network to a link circuit on the other side of the network it being possible, when traffic conditions so demand, to set up such a call by connecting the calling terminal to one side of a so-called transfer circuit by a first such normal connection across the network to a first link circuit and by connecting the called terminal to the other side of the transfer circuit by a second such normal connection across the network to a second link circuit. The transfer circuit in effect connects two normal connections in series where a single such connection is not available. The link circuits are of the kind described in Specification 1 ,041,757 being connected on each side to a network terminal having access to local subscribers' lines and a network terminal having access to trunks, either terminal on one side being connectible to either terminal on the other side by way of a reversible feed bridge or a through bridge. In connecting local subscribers with a pair of normal connections, series connected by a transfer circuit, one of the link circuits will employ a feed bridge and the other link will employ a through bridge. The transfer circuits are connected on both sides to verticals of A- rank switching arrays which over other verticals give access to trunk lines exclusively. Each transfer circuit has four hold wires each of which is connected only to those horizontals of the A-rank array which lead to the respective four sections of the B and C switching ranks. A transfer circuit is described with reference to Fig. 11 (not shown).

Abstract: 952,652. Two-part couplings. BELLING & LEE Ltd. - June 29, 1962 [Sept. 8, 1961], No. 32278/61. Heading H2E. [Also in Division E2] The slit socket contacts 41 of one half of a connector engage the pin contacts 18 of the mating half within the bores of a clamping member 31, and are then retracted by means of camming members on the two halves into narrower parts of the bores so that they are squeezed about pins 18. The connector comprises plug pin-and-socket supports 17, 40 held respectively in casings 1 and 19, the clamping member 31 fixed in casing 19 and having narrow bores 33 opening into wider bores 34, and pivoted members 43, 44 connected by a bridge 47. When casing 1 is inserted into the lower part 20 of casing 19, a spigot 14 on the former enters a slot 26 and plug pins 18 enter slotted sockets 41 within the wider bores 34 of clamping member 31. The member 43 is pivoted about a boss 28 on casing 19 so that a slot 51 in the former engages spigot 14 and cams casing 1 into the position shown in Fig. 3. The pins 18 are now fully engaged in sockets 41, and a spigot 42 on socket support 40 which protrudes through casing 19 and has hitherto been stationary begins to move back under the action of a part 57 of a second camming slot 54, while the pins 18 continue to move forward correspondingly. The sockets 41 are thus retracted into the narrower bores 33 of member 31 and the slots therein close so that the sockets grip the pins 18. The pivoted member 44 acts similarly on the opposite side of easing 19 and the process described above may be reversed to withdraw pins 18 from sockets 41. Specifications 920,572 and 952,651 are referred to.

Abstract: 881,343. Distilling zinc. NATIONAL SMELTING CO. Ltd. Sept, 3, 1959 [Oct. 16, 1958], No. 33110/58. Class 82(1) Substantially pure zinc is obtained from lead containing both zinc and cadmium by distilling the lead to produce cadmium-containing zinc vapour which is partially condensed by contact with cooled solid body of zinc so that the uncondensed vapour becomes enriched in cadmium, collecting the molten zinc running off the solid body in a pool and heating the pool by direct conduction from the molten lead from which the zinc and cadmium have been distilled so that the cadmium-enriched vapour is redistilled from the pool which is thereby further impoverished in cadmium In the apparatus shown in Fig. 1, zinc and cadmium-containing lead enters by a pipe 2 to fill a well 3 and overflows a lip 7 to flow downwards over the inner surface of a wall 5. Cadmium containing zinc vapour is condensed on a condenser 12 having cooling coils 18. The upper part of the condenser is provided with a heat insulating lining 14. At a certain thickness of deposit 19 the vapour condenses as liquid and drips into a tray 20 heated by lead which has flowed over the walls 5. Cadmiuim-enriched vapour redistills from the tray which thereby contains substantially pure zinc. Vacuum is maintained via a pipe 16 and cadmium-enriched zinc vapour condenses in a cold trap 15. The cold trap may be replaced by a bayonet-type cooler and an annular system of inclined shelves may be fitted around the condenser to form an additional zinc refluxing stage as described in Specification 846,152.

Filed: 1920-11-25
Abstract: 176,087. Weeks, E. O. Nov. 25, 1920. Radiators, motor-car.-An arrangement for preventing waste of the circulating water or other liquid and for replenishing the radiator automatically comprises an overflow reservoir 3 open at the top to the atmosphere, a pipe 9 connecting the upper part of the radiator with the intake of the engine or other suction device, and a float valve 10, Fig. 2, controlling the connection with the pipe 9. The filling-cap 5 of the radiator fits in an airtight manner. When the water or other liquid becomes heated as the result of the working of the engine, it expands through an overflow pipe 4 into the reservoir 3, and the float 11 falls to open the upper part of the radiator to thepipe 9. The vacuum created by the engine suction or other means then causes a return of theliquid from the reservoir 3 to the radiator. A non-return valve 13 in the pipe 9 prevents a flow of air from the engine to the radiator when the engine is stopped. In a modification, Fig. 3, a float valve 10<1> controls the entrance of air through a passage 15 to break the vacuum in the radiator and pipe 9 when the liquid level rises.
