Title: Improvements in or relating to systems of distribution of programmes of music, news or the like
IPC: H04H20/81
Filed: 1937-12-11
Abstract: 500,139. Distributing music &c. GENERAL ELECTRIC CO., Ltd., and CHUBB, A. A. Dec. 11, 1937, No. 34329. [Class 40 (iv)] In a system of distribution of music or the like from a telephone exchange, a subscriber connects his line to the desired programme through a selecting switch at the exchange, the selection being effected by a line current of variable strength corresponding to the desired operation. Fig. I shows two line wires LA and LB connecting a subscriber's telephone instrument S and loudspeaker T to an exchange, where the lines are connected to line switch wipers G1, G2 and to contacts A1 and A2 leading to the programme supply. At the subscriber's station there are provided a change-over switch having contacts N1, N2 and a selecting switch M which is in effect a variable resistance. All the relays and selector switches at the exchange are under the control of relays 'C, D. When the receiver is lifted the lines are looped and both relays C and D are operated. Operation of D causes the wipers G1. G2 to hunt for an outlet and breaks the contact D1, thereby paralysing the programme-selecting apparatus which is set into operation by relay C. When a programme is required the change-over switch N1, N2 is operated and the wiper of the switch M is set on the stud corresponding to the desired programme. Relay C is operated, and as relay D is not operated, the select. ing operation can take place. Closing of contacts Cl, C2 operates relays A, B and a magnet E. Magnet E by interaction with C steps until the currents in the two coils of relay C are equal and the relay does not operate. The relay A, which is slugged, then allows the contacts A1, A2 to connect the desired programme to the lines. To turn the programme off the subscriber momentarily closes a switch Q, looping the line and operating both relays C and D. the latter releasing relay B. The change-over switch is thrown immediately afterwards. Fig. 2 shows a modification in which the selecting switch E1 is connected in series with a relay A in the anode circuit of a valve Z. When the subscriber operates busswitch M, the switch E1 steps round so as to reduce the anode current until, at a critical value of the current, A releases and the selection is complete. Switch M controls the anode potential of the valve by varying the signal current and hence the potential of the filament of Z. An amplifier or an amplifier-detector R may be connected between the line and the loudspeaker according to the frequency of the programme currents.

Abstract: 801,887. Stretching. FIELDING & PLATT, Ltd. Nov. 22, 1956 [Dec. 2, 1955], No. 34630/55. Class 83 (4). A machine for stretching metal plates and other members comprises a pair of cross-heads for gripping opposite ends of a member to be stretched, an hydraulically operated main ram for loading one crosshead in a direction away from the other to stretch the member gripped therebetween, a framework extending between the cross-heads for supporting the thrust therebetween during the stretching operation, and shock-absorbing means for dissipating at a controllable rate the energy released consequent upon sudden relative movement of the crossheads due to the fracture of the member being stretched. Plate to be stretched is gripped between a pair of cross-heads 1, 2 between which extend a pair of frame or compression members 3, one on each side of the longitudinal axis of the machine, the cross-head 1 being adjustably positioned relative thereto by pins 4 in holes 5 in the members 3. Each frame member 3 has secured thereto at its other end a cylinder 6 in which a ram 7 engages the other cross-head 2 to load it away from the head 1 to stretch the plate. To absorb shock if the plate should break, the ram 7 is hollow and contains a hollow plunger 12 secured to a stirrup 13 which through tie-rods 13a and compression springs or rubber buffers 14 is connected to the side frame 3. The other end of the plunger 12 slides in a recoil cylinder 15 supported on an end wall 10 of the machine pit and containing a plunger 16 urged outwardly of the cylinder 15 by compressed gas. On sudden outward movements of the cross-heads 1, 2 consequent upon failure of the plate being stretched the volume 11 inside the ram 7 will be reduced and the sudden increase in pressure in the hydraulic fluid therein will first be absorbed by the recoil plunger 16 and the fluid then exhausts through a port 18 and variable orifice valve 19. The ram 7 may be positioned before stretching by admitting fluid through a valve 20 to the space 11 in the ram, or through a valve to the space behind the head of the plunger 12. To position the side frame 3 a plunger 22 secured thereto moves in a cylinder 21 on the other end wall 9 of the machine pit, this cylinder being connected through a pipe 23 to the main cylinder 6. Similar shock-absorbing means may be provided at each end of the machine. The side frames 3 may be rigidly secured together or to a foundation. Specification 801,888 is referred to.
