Class 51(ii) Apparatus for cooling heat-treated materials e.g. coke, cement clinker, lime, and particularly sinter discharged from sintering machines, comprises a rotary annular bin C with a cross-section narrowing towards the bottom having an inner retaining wall 57 rising from an annular refractory lined self 60, an outer retaining wall 64 terminating short of the shelf 60, the bin being supported from a centre bearing member D by a structural steel frame 5 comprising spoke-like members B extending radially from the centre of the frame. Each member B consists of upper and lower I-beams 46 and 10 respectively, interconnected by diagonal braces 43, 44 and 45, the beams 10 being attached to a central hub 12 disposed over a ball-bearing on a shaft 34 and the beams 46 connected to circular plates 52 and 53 held together by a locking pin 55. Each brace 43 supports a horizontal arm 48 to which is attached a depending arm 50 extending downwardly and inwardly. A circular steel plate 57 secured to the beams 43 forms the inner wall of the bin and is topped by a circular steel guard 58, another circular steel plate 64 forming the outer wall of the bin. Loss of material from the shelf 60 during rotation of the bin is prevented by a fixed circular side guard 102 disposed around the periphery of said shelf and formed with openings 113 to permit the insertion of adjustably pivoted discharge ploughs 94 each of which is associated with a hopper 99 provided with an outlet opening feeding a belt conveyer. Water spray pipes 140 may be disposed above the bin, which is fed with material to be cooled by a shoot 120. The bin is rotated by three or more driving wheels 68 mounted in cradles 70 and coupled to electric motors 74, a series of idler wheels 76 spring mounted in cradles 78 being disposed between each driving wheel. The wheels 68 and 76 engage a circular track 82 mounted on beams 85 on the underside of the bin. Specification 605,423 is referred to.

Title: Improvements in and relating to automatic clothes washing machines
IPC: D06F15/00
Filed: 1945-07-27
Abstract: 596,484. Washing-machines. HARRIS, W. J. July 27, 1945, No. 19240. [Class 138 (ii)] A pulsating agitator for use in the waterheating vessel 3 of a washing-machine comprises a bell-like body 10 carrying valve means which are normally closed by contact with the articles 4 on the floor of the vessel and are adapted to open when, by reason of the steam rising from the heated water in the vessel and becoming trapped in the body 10, the latter is lifted a suitable distance above the said articles. By this means, so long as steam is given off by the heated water, the body 10 is automatically lifted each time it drops after the release of the trapped steam. The apex of the body 10 is provided with a valve housing 11 from which depends a valve stem 12 passing at its lower end through an opening in a spider member 13 on the base of the body. The lower end of the stem 12 has a disc 14 which contacts with the articles 4, and its upper end is surmounted by a closure device 15 which is enclosed by the housing 11 and is adapted to co-operate with the vent 16 in the roof of this housing. As the body 10 rises due to the trapped steam, the fact that the articles 4 yield a little when relieved of the weight of the agitator ensures that the valve 15 will be retained in its closed position for a time sufficient for the agitator to lift a short distance. The vessel 2 is suspended within a double-walled shell 5 from a top plate 6, and may be heated by gas, electricity or other means.

Title: Improvements relating to magnetic record reproducing apparatus

Abstract: 988,391. Automatic speed controL ELECTRIC & MUSICAL INDUSTRIES Ltd. May 29, 1961 [June 2,1960], No. 19537/60. Heading G3R In apparatus for reproducing colour television signals from a magnetic tape 1, signals picked up by rotatable heads 8 are applied to gating circuit 14, synchronized by pulses from head 11 associated with tone wheel 10, so that the signals are gated in cyclic order to output channel 15. The signals in the channel 15 are in turn applied to a reproducing circuit 16, comprising amplifiers and a F.M. demodulator from which is derived the video signal output of the apparatus. The signals recorded on the tape are disposed in a series of disconnected paths across the width of the tape, successive tracks being scanned in sequence by the different heads. To control the speed of the tape relative to head-wheel 7,a head 17 is associated with a reference track along one edge of the tape, the timing of the pulses from this head being compared with that of the pulses from the head 11 in discriminator 18. Any difference in timing produces an error signal for varying the speed of capstan motor 6 so as to reduce the difference. For more accurate control, a portion of the output signal from circuit 16 is applied to gate 20 which passes only the colour bursts to a continuous oscillator 21 to control the phase and frequency of the output oscillation in correspondence with the colour bursts. An oscillator 23 generates a stable reference oscillation for comparison with the output of oscillator 21 in a phase discriminating circuit 24. The error signal from the circuit 24 controls the phase and frequency of head-wheel motor 9. In another embodiment, adapted for monochrome television signals, the gate 20 is replaced by a gate to which signals from the circuit 14 are applied before demodulation. This gate receives, as gating signals, line synchronizing signals which are separated from the video signal after demodulation. The signal on the tape is recorded as a frequency modulation of a carrier wave, the output from the gate comprising selected samples of the carrier wave which are compared with a reference oscillation. Specifications 843,097, 919,481 and 949,212 are referred to.

Abstract: 299,099. Automatic Telephone Manufacturing Co., Ltd., and Ostline, J. E. July 22. 1927. Automatic exchange systems.-In a system in which, when busy condition is encountered at any stage, tone is transmitted back to the calling party trom the relay group feeding battery to the said party, the line is looped at the relay group to hold the partly established connection, but tone current is prevented from being fed forward. The invention is described in a modification of the first code selector described in Specification 270,782, jumpered connections being provided so that the circuits can be readily converted to effect release of the succeeding switches when busy condition is encountered. The modifications comprise mainly the provision of (1) additional armatures BR6, BR7 for busy relay BR to open the outgoing wires, (2) jumpered connection 11. 12 to complete the loop formed by relays D. I, which would otherwise be broken when BR is energized, (3) jumpered connection 13, 14 to preserve the locking circuit of relay B. The application of the invention to an outgoing repeater is mentioned. Detailed description. During the setting up of the connection over subsequent switches, relays I, L, A, B. BS, K, and one of the switching relays H. N are operated. On busy condition being encountered, the register controller sends out the full number of impulses and releases K which completes the loop formed by relays DI in series, and busy flash battery is connected to the lower speaking wire. When I restores on the first application of battery, the locking circuit of BS is broken at I1 so that when I reenergizes at the next application of ground. BR operates over BR2, BS3, I1, BS2, B2. Relay BR locks up over BR2, K1, L1, M (upper), opens the outgoing wires at BR6, BR7, and connects intermittent busy tone to calling party over BR1 and L (lower). The contacts BR3, BR2 are shunted by jumpered connections 11, 12 and 13, 14 respectively so that the loop is maintained and the locking circuit of B preserved. Release takes place when calling party hangs up. Forward transmission of tone currents may be prevented by short circuiting the outgoing wires together, but this would not give normal release. If the first code selector fails to find an idle outlet, busy tone is connected up over CS, A (lower). N4. H3, R4, L2, BR7, operation of BR being in this case unnecessary. Standstill releases. Arrangements for effecting release if subscriber fails to dial, or dials only one digit or the complete exchange code, similar to those described in Specification 270,782, are mentioned. Premature dialling. If dialling is commenced before an A-digit switch has been taken into use, intermittent opening of the circuit of L opens the initial circuit of A at L2 so that M operates over B2, D1, A1, C3, K8, M5. M locks up to release conductor 3 and at M2 prepares a circuit for BR which becomes effective when change over relay C falls back. NU tone is then connected up over M4 and BR1.
