Abstract: 1,123,990. Transmission systems. CONTROLE BAILEY S.A. 8 June, 1967 [8 June, 1966], No. 26620/67. Heading G4H. Each sub-station of a transmission system in which a plurality of sub-stations 2, 3, 4 (Fig. 1) are connected to a central station 1 by a single channel 5 includes an oscillator 22, sensor 21 and a delay circuit 25 which delays an interrogating signal from the central station 1 before transmitting it to the next sub-station, the interrogating signal enabling the oscillators so that frequency-modulated signals from the oscillators 22 representing measurements effected by the sensors 21 are sequentially transmitted to the central station 1. In the embodiment described the interrogating signal comprises a positive pulse followed by a negative pulse, the latter resulting in the normal frequency of the oscillator being transmitted to compensate for drift of the oscillator. At the central station the measurement signals are fed to a counter 15, the contents of which are supplied to a multi-register store 16. The circuitry of the sub-station may be transistorized (Fig. 2, not shown) or if the interrogation pulses are long enough relays may be used (Fig. 3, not shown).

Title: Improvements in or relating to electric pulse demodulators
Inventor: MIRZWINSKI HENRYK
IPC: H03K9/02
Filed: 1955-09-19
Abstract: 802,742. Pulse modulation circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 18, 1956 [Sept. 19, 1955], No. 26694/55. Class 40 (5). A pulse amplitude demodulator comprises means for subtractively combining amplitudemodulated pulses with unmodulated pulses of the same recurrence frequency in a rectifier circuit to give a resultant demodulated output, which appears across an integrating circuit. In one embodiment two identical diodes D and resistors R form a network to which modulated negative-going pulses are applied through condenser C2, and unmodulated positive-going pulses are applied through condenser C3, the remaining and opposite junctions of the network being shunted by an integrating condenser Cl. The values of C2 and C3 ensure that diodes D are non-conducting between pulses. When equal amplitude pulses are applied the bridge is balanced and condenser C1 develops no charge. When the pulses applied at 1 exceed in amplitude those at 2, condenser C1 is charged negatively and when they are less it is charged positively, the condenser holding its charge and the diodes being alternately and individually conducting and non-conducting. Thus the output across C1 is a stepped sinusoid corresponding to the envelope of the amplitude modulation impressed on the pulse. In a step waveform generator, Fig. 2 (not shown), a pulse train modulated by a linear sawtooth waveform is demodulated to produce a stepped sawtooth, the shape and stepping of which may be varied by adjustment of the sawtooth source and demodulating pulse source.

Title: Improvements in or relating to valves for fluids
Inventor: ELLINGER JOHN HENRY
IPC: F16K1/22
Filed: 1955-09-20
Abstract: 833,334. Valve closure members. MINISTER OF WORKS. Dec. 19, 1956 [Sept. 20, 1955], No. 26879/55. Class 135. A valve comprises a vane having two parts arranged to execute a rolling motion in the same direction as each other about a circle to open and. close effective opposite marginal portions of the vane with respect to a seating; the rolling parts being operatively and positively interconnected by one or more flexible bands or belts carried by the vane and/or by gearing so that fluid pressures acting on the rolling parts at the same face of the vane cancel each other. Thus the rolling action can be effected with comparatively small effort. Fig. 7 shows a valve comprising a fixed cylinder 1 about which roll in the same direction two rollers 2, flexible strips 3A, 3B, Fig. 3, fixed at their ends to the rollers being wound about the rollers and on opposite sides of the cylinder 1. The rollers are also directly connected by further flexible strips 3C, 3D clamped between the rollers and shaped bodies 4. As the rollers 2 are rotated about the cylinder 1, e.g. by pins 7 projecting from a worm-wheel 7A, the bodies 4 are turned out of the general plane of the vane, as shown in Fig. 7, and constituted by the parts 1, 2, 4 and the flexible strips, so that they engage the walls of a conduit or the like to shut off fluid flow, as shown in Fig. 4. Longitudinal relative movement between the cylinder 1 and the rollers 2 is prevented by separate spacing- rings 6, Fig. 2, or annular ridges machined on the cylinder, engaging grooves 5. Several such vane-like structures may be arranged across a conduit and operated simultaneously by worm gearing so that the vanes meet end to end when the conduit is closed. The flexible strips 3A, 3B may be dispensed with and the rollers connected to the cylinder by gears.

Filed: 1945-10-15
Abstract: <PICT:0614633/III/1> <PICT:0614633/III/2> <An apparatus for analysing exhaust gas resulting from combustion of hydrocarbon fuel and air by measuring changes in thermal conductivity of a gas in a thermal conductivity cell as determined by variations in the resistance of the filament of the cell, comprises a bridge circuit having in one arm a first thermal conductivity cell and in an opposite arm a second cell of twice the sensitivity of the first cell, means for supplying the exhaust gas which contains water of combustion in the vapour phase to the first cell and means for supplying dried exhaust gas to the second cell, whereby the second cell cancels the effect on the bridge of carbon dioxide in the first cell and in addition produces an equal effect in additive relation to the effect of water vapour in the first cell.  According to Fig. 1, exhaust gas is supplied by exhaust pump 27 to cells having filaments 10, 11 and 12, 13 and arranged in series in opposite arms of a Wheatstone bridge circuit; the gas enters the circuit through a conduit 19, constriction 29 and cell 20 containing heated copper oxide or other oxidizing agent, then contacts filament 10, passes through a drier 22, contacts filaments 12 and 13, and finally contacts filament 11 after passing through a carbon dioxide absorber 24. Instead of a single stream, the gas supplied may be divided into parallel streams and treated separately. The circuit shown in Fig. 2 compensates for atmospheric humidity and employs the same bridge arrangement as that of Fig. 1, but has two filaments 30 and 32 of equal sensitivity and two filaments 31 and 33 of double the sensitivity.  Exhaust gas supplied through conduit 43 &c. is divided into a main stream which contacts filament 31 and a minor stream which is drawn through a constriction 46 to contact filament 32, the gas in this section being maintained at a low pressure by valve 49 and pump 54 which also maintain a flow of air at the same pressure in contact with filament 30.  Filament 33 is in contact with air saturated with water vapour.  The walls of the cells are preferably kept at the same temperature for respective pairs or for all the cells by forming them in a metal block.
