A tungsten composition, for making incandescent filaments which do not suffer from arc-discharging, comprises:- Tl 0À0001-0À1% K up to 0À0002% as a natural impurity, and optionally residual amounts of an oxygen containing Si and Al compound or an oxygen containing Si and Ga compound, corresponding to amounts known per se to be necessary to form a large-crystalline structure, the balance, apart from impurities and incidental elements, being tungsten. The compositions are made by mixing a Tl compound with tungsten oxide with a ratio Tl2O3/WO3 of 0À0001-0À05, reducing to metal powder in hydrogen, pressing the powder into rods which are sintered, hammered and drawn into wire which is formed into the filaments. The appropriate amount of Si, Al and Cga compound may be added to the initial powder to form largecrystalline tungsten bodies.

Title: Radio receivers

Abstract: 1480774 Receiver muting and synchronous detectors SONY CORP 19 Sept 1974 [28 Sept 1973] 40925/74 Heading H3Q In a radio receiver including a phase-locked loop comprising a phase comparator 5, a LPF 6 and VCO 7, the phase comparator is supplied with an incoming AM carrier wave and the output of the VCO, a demodulator 2 is supplied with the incoming AM carrier wave and the output Eo(t) of the VCO to produce a demodulated output signal Ep(t) and a muting circuit 12 is controlled by the output of the LPF 6 and is connected to the output from the demodulator so as to allow signals to pass only in response to an output signal level from the LPF 6 corresponding to the phase-locked condition of the loop 20. As shown an AM carrier at IF is connected at 1 via an amplifier limiter 3 and a phase shifter 4 to the phase comparator 5 and is connected to a synchronous detector 2 which enables a demodulated output from a LPF 8. When the receiver is tuned to an incoming carrier signal the phase locked loop 20 is locked and there is no output signal through amplifier 9 and detector 10 so that a voltage comparison circuit 11 produces no output signal and muting circuit 12 allows the demodulated output from the LPF 8 to pass to output 13. When the tuning of the receiver is changed from one station to another only noise signals occur and the loop 20 is not in a phase-locked condition. When the signal applied to the voltage comparator circuit 11, from the LPF 6 via amplifier 9 and detector 10, exceeds a predetermined value the output signal from the comparator 11 makes the muting circuit non-conductive to prevent the noise signal passing to the output 13.

[Also in Division G3] Lengths L2 of potato, fish, ground meat, or banana meal, are intermittently extruded by a piston 25 through orifices 33 of a plate 32 from which they are then severed, to fall into a gasket 89 or on to a conveyer, by a cutting plate 47 the orifices 48 whereof are reciprocated out of alignment with the orifices 33 against a return spring 51, by one or more solenoid 59 actuated plungers 60, the piston 25 being driven for a predetermined time by a rack 22 and pinion drive, from a reversible electric motor M which is energized through a manually adjustable time delay relay 69 to adjust the extruded lengths L2, and the solenoid or solenoids 59 also being actuated through a time delay relay 78 after the motor 72 has been stopped for a predetermined time period. The piston 25, which as well as the plate 32 comprises acrylic plastics, is detachably mounted to a rod 21 comprising the rack 22 which includes a guide slot engaging a pin in an upper plate 16 which carries the piston drive and is mounted to four posts, e.g. 12, 15, on which are also mounted the solenoid or solenoids 59, and also carries a structure 30 which carries the plate 32 and a meal container 26 in which the piston 25 is displaced.

In the engine shown in Fig. 1 air from the compressor 40 is pre-heated in heat exchanger 42 and passed through line 43 to the combustion chamber which comprises an outer casing 1 and an inner flame tube 2, the flame tube being formed with openings 7 for inflow of primary air and openings 8, 9 for inflow of secondary air. An axially-movable ring valve 10 is disposed around the flame tube being shown in the position in which it closes the secondary air openings 9. The position of the ring valve is controlled in dependence on temperature of air entering the combustion chamber, the temperature being sensed by the device 21 and the signal produced acting through the actuator 23 and rod 12 to position the ring valve. Alternatively the ratio of or the difference between the air preheater inlet temperature and the combustion chamber inlet temperature may be used as the control parameter.

In Fig. 4 (not shown) a temperature sensing element is mounted in the actuating rod 12 within the air jacket space of the combustion chamber. In Fig. 5 air-flow through opening 37 to the secondary air inlets 34, 35 is controlled by a bi-metallic valve member 38. In Fig.6 (not shown) air-flow in an annular space around the outer wall of the flame tube is controlled by an axially movable ring valve; thus air-flow to the secondary air openings is controlled.
