Title: Improvements relating to automatic telecommunication switching systems
Inventor: WARMAN BLOOMFIELD JAMES
IPC: H04Q3/00
Filed: 1959-01-01
Abstract: 916,634. Automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 31, 1959 [Jan. 1, 1959], No. 101/59. Class 40 (4). In a system in which, in response to a call, a start circuit seizes a register which thereupon controls the setting to the calling line of a primary switch over which the call can be set up, is started when the control circuit is seized, and stopped when either the primary switch is set, or if a further line becomes calling, the timer being a timer operable to give an alarm and/or take other appropriate action if it is not stopped before a predetermined time has elapsed. As shown, a calling loop L causes potential to be applied to marking and start leads W L  and stl L , the latter operating start relay ST which causes the line hunter F to hunt for the marked lead m L , whereupon test relay T stops the switch. Relay ST also causes a register selector H to hunt for a free register which when found operates TF to stop the selector. Relay T operates TS and TF brings up TFS. Relay TS releases ST. Relays TS, TFS bring up TT and STT follows to start the timer TM. Relay STT releases TS and TT follows. Relay STT is now locked up in dependance on T being operated and ST being released. The register meantime has received the coded identity of the calling line and sets the line finder LF in accordance therewith using the revertive impulsing technique. When the calling line is thus connected to the transmission bridge earth is put on the P-wire by BB in the usual manner to bring up K which removes the marking potential from m L  so that T releases followed by STT. If, however, due to a fault this fails to happen, and no other call is present so that ST remains down, the timer TM eventually operates AB which may either bring up an alarm or as shown bring in second start circuit STC2 by changing over the condition of relay CO. This in turn operates PG in STC and releases PG in STC2 to disable the one and enable the other. The second start circuit may then make a fresh attempt to set up the connection. In the event of a second call being present, however, this receives attention first. Thus ST releases STT to disconnect the timer TM and to partially enable the circuit for test relay T. Differential relay D, however, is up having been brought up by TT so that T cannot yet operate and F moves on. The bridging wiper of F4 now releases D by differential action so that T may now operate to the next morked line. Specification 886,279 is referred to.

Title: Improvements in or relating to vane motors, spinners and the like for imitation fires and other purposes
IPC: F24C7/00
Filed: 1936-01-02
Abstract: 469,934. Imitation fires. PREMIER ELECTRIC HEATERS, Ltd., COLLINS, H. F., and NEWTON, A. E. Jan. 2, 1936, No. 104. [Class 126] [Also in Group XVIII] In a spinner 10 for imitation fires, or for advertising or display apparatus, the air or gas currents which impinge on the vanes 15 or equivalent surfaces and produce rotation are deflected from the vertical. in the direction of rotation. The direction of the currents may be variable, or may be fixed initially. In the form shown in Figs. 2 and 4, air enters the chamber in which the spinner is located, through an aperture 20 and a duct formed by the walls 19, 21. Pivoted in this duct at 29 is a substantially triangular flap 28, which is movable into positions such as those shown in Fig. 4. This flap may be adjusted by moving a rod 31 pivotally attached to a lug 32 on the flap, or by a lever linked to the flap. A friction spring 30 holds the flap in its adjusted position. The flap might alternatively be of deformable metal fixed in the channel and bent to the required position before use. In another form, Fig. 5, air is supplied through a pair of tubes 44, 45, which converge upwardly and are controlled by shutters 46 rigidly connected and pivotally mounted. Instead of having vanes, the rotor may be of substantial thickness with inclined air passages. Specifications 404,302 and 450,149 are referred to. According to the Provisional Specification, the speed of air flow may be varied without varying the angle at which the air currents impinge on the vanes.

Abstract: 325,661. Davis, N. R., and Associated Electrical Industries, Ltd. Jan. 8, 1929. Induction furnaces.- The top part or mouth of the lining or crucible of a coreless induction furnace is sintered by inserting a metal ring 5 of heavy cross-section in the mouth of the crucible and inducing eddy currents therein by means of the furnace coil. The silica or magnesite with or without a binder is rammed between the metal pot 3 and ring 5 and the furnace coil 1 and casing 2. A lip or spout 6 is provided in the lining which is formed from ganister at this part. The furnace is charged and the coil energized but until the pot 3 fractures by fusion it shields the ring 5 electromagnetically. As the charge melts it exerts a shielding action on the ring. During the period between the fracture of the pot and the melting of the charge considerable heat is developed in the rings 5 and the adjacent lining is sintered. When the furnace is tipped to pour the melt part of the ring is melted and a gap b, Fig. 2, is formed therein. During the next melt intense heat is developed at the part c which melts and renders the ring discontinuous.
