Patent GB-352651-A (GB)
Title: Improved process for the extraction of ethylene glycol or its homologues
IPC: C07C31/20
Filed: 1930-05-24
Abstract: Ethylene glycol is extracted from solutions containing calcium chloride or magnesium chloride such as are obtained by saponifying olefine chlorides with alkaline-earth carbonates, by distillation in vacuo at temperatures of 250-400 DEG  C., while maintaining the mass continually in motion by stirring, distribution in a thin layer, or other suitable means.  Thus the liquid may be treated in a thin layer vacuum drier the drum of which is heated to 300-320 DEG  C.  Another method consists in adding heated glycol to the solid glycol-calcium chloride addition compound formed by heating the solution in a thin-layer vacuum drier at 170 DEG  C., and heating the liquefied mass in a second similar drier to 320 DEG  C.  The process may also be carried out continuously by causing the liquid containing glycol and calcium chloride after a preliminary concentration to flow through a horizontally disposed tubular vacuum apparatus provided with stirring means, from the end of which dry calcium chloride is discharged, the aqueous glycol vapours driven off being led back over the entering material and finally condensed.  The highest temperature of the mass passing through the evaporator is 280-320 DEG  C. Concentrated glycol may be obtained from the aqueous condensate by rectification.

Title: Carrier current vestigial sideband television receiving system
Inventor: MCALLAN JOHN GILBERT
IPC: H04N5/455
Filed: 1961-05-03
Abstract: 900,824. Automatic phase control systems. STANDARD TELEPHONES & CABLES Ltd. May 3, 1961, No. 16041/61. Class 40 (5). In a television vestigial sideband receiving system a demodulating oscillator 5 is locked in phase, by a phase comparator 15, with the incoming carrier during line synchronizing intervals when a gate 6 is opened to the carrier, the gate being operated by a sampling pulse generator 9 actuated from the amplified output of the demodulator 3. Negative modulation of the carrier is used and with reduced amplitude of the carrier (excess carrier ratio=¢ for example) and if during over-modulation peaks the demodulator output operated gate 6 to pass an undesired phase-reversed carrier signal wrongly synchronizing the oscillator (with opposite phase) this condition would be unstable due to the more numerous line synchronizing pulses occurring during frame synchronizing intervals when the carrier is never overmodulated. A filter 8 also permits direct synchronizing of the oscillator 5 from the gate 6. Two stages of demodulation can alternatively be used.

An automatic suction valve may be placed between cock 11 and the pump casing. In a modification, Fig. 2, a pump 6 serves for measuring the hot water flowing from pipe 10, and a pump 6<1> for supplying the air under pressure, a suction valve 10<1> being provided thereon. In a further form, Fig. 3, the hot water is supplied under pressure through tube 10 to the strainer 5 from the hot water vessel, under control of a cock 16, the pressure being obtained, for example, by connecting the hot water vessel direct to the water main. The air pump 6<1> is provided as before. In a complete machine embodying the pump construction of Fig. 3, the hot water vessel 22, Fig. 4, and the air pump 30 are enclosed in a casing 17 closed by a hood 18, and are carried by a support 34 secured to a plate 19 supported on a hollow central pillar 20 through which the water and other connections pass. The infusers 4 are suspended from support 34 with their spouts 3 spaced above cup trays 24 mounted on the base 21 of the apparatus. The air pump 30 is operated by a handle 30<1> actuating a toothed sector 31 meshing with a rack 32 fast with the piston rod. The air is supplied through pipe 33 to the infuser 4. The hot water vessel 22 has an insulating lining 23 and electrical or other heating means, and receives water under pressure from a main. The upper part of the vessel 22 is connected to each infuser 4 through a pipe 29 and a valve 27 operated by a handle 28. An outlet is also provided for drawing off hot water direct from vessel 22.

Title: Improvements in devices for supervising the speed of vehicles during braking
IPC: B60L15/20
Filed: 1961-05-08
Abstract: 947,526. Indicating electrically. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 8,1961 [May 11, 1960],No. 16632/61. Heading G1N. [Also in Division F2] A device for supervising the braking and speed of a vehicle (e.g. a train) includes a voltage source D whose amplitude is proportional to the speed V, a variable resistor R whose value is progressively decreased as a function of a prescribed braking distance S, and a moving coil wattmeter connected so as to determine the quantity V<SP>2</SP>/S, which is proportional to the deceleration. Constant deceleration is maintained by keeping the meter indicator in the centre of a display scale. In series with R is connected a small auxiliary resistor r, which over the first 18% of the braking distance is progressively increased, and over the last 6% is progressively decreased. The resistors are preferably varied in steps and actuated by pulses from an adjustable source, a pulse frequency divider being provided so that r is returned to zero during the final reduction. Resistor r permits matching of the braking characteristic C (Fig. 3) to the practical curve A. The device may also be used during reduction of speed to a new value V 2 :R and r are initially progressively decreased and increased respectively, then R continues to decrease alone, and finally r is made to decrease alone. An automatic alarm may be provided to show when the indicator gives an excessively large reading, indicating that the braking force is insufficient, or that a predetermined speed limit has been exceeded, so that emergency braking may be initiated, if desired.

Abstract: 577,949. Aircraft power plant. BRISTOL AEROPLANE CO., Ltd., and OWNER, F. M. Dec. 24, 1941, No. 16654. [Classes 4 and 114] A power plant for aircraft comprises an internal-combustion engine and airscrew supplemented by a jet propulsion unit, and the cooling air from the engine or radiator and the exhaust gases from the engine are continuously discharged through an opening in the aircraft through which the high velocity jet from the jet propulsion unit is directed. The jet propulsion unit includes a compressor, a combustion chamber and a turbine for driving the compressor. The rear end of an engine nacelle is shown housing a jet propulsion unit 11 discharging from a tube 12 and nozzle 13 through an opening 14 in the cowling. The nozzle 13 is carried by a sliding sleeve 17 to adjust the annular space at the opening. The ejector action draws the cooling air from the engine or radiator, or other vitiated air, through the annular passage 20, and the exhaust gases are led through pipes 16 to the vicinity of the opening, or, as shown in chain lines, into the tube 12. In a modification, an aerofoil-section sleeve is spaced from and surrounds the end of the sleeve 17. The air cools the jet propulsion unit when the latter is in use and keeps it sufficiently warm when not in use to facilitate restarting.
