Abstract: 564,323. Wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., SEATH, E. G., and HIGHNAM, K. March 19,1943, No. 4541. [Classes 40 (iii) and 40 (v)] Arrangements for tuning over a frequency band an antenna coupled to a transmitter over a length of transmission line, is characterised in that the length and characteristic impedance of the line are such that the line together with the antenna present to the transmitter a constant resistance over the desired frequency band, and means are provided at the transmitter, for neutralizing the reactive component of the transmission line and antenna. As shown, the output transformer T of a power amplifier PA is coupled through a transmission line TL to an antenna ANT. The line is chosen so as to present a substantially constant resistance to the transformer throughout the frequency range, and the inductance is neutralized by a series of condensers C1 ... C6 successively switched into circuit by an arm b ganged to the main tuning control of the transmitter. Alternatively, the condensers C1 ... C6 may be replaced by a variable condenser having a suitable law of variation. For light loads, requiring a small coupling coil L2, it may be necessary to insert an inductance in series with the line TL. Also, to increase the resistive component with frequency, a capacity C7 may be coupled across the windings of the transformer T.

Title: Improvements in or relating to anti-freeze devices for motor cooling systems
IPC: F01P11/20
Filed: 1937-02-16
Abstract: 471,146. Cooling systems for engines. SEMON, D. E. Feb. 16, 1937, No. 4603. [Class 29] The cooling system of an internal - combustion engine comprises a radiator having a header tank 8 and a bottom tank 11 connected together by a plurality of tubes 9, the bottom tank constituting a storage tank into which the water drains when the engine is inoperative and having heat-insulated walls, conduits 45 50 for connecting the top and bottom tanks to the engine a vent tube connected with the bottom tank, a conduit for connecting the cooling system with the intake manifold of the engine whereby water is drawn from the storage tank when the engine is started and a float valve in the conduit for cutting off communication between the cooling system and the intake manifold and arranged to be closed when water in the cooling system is at a predetermined level. The storage tank 11 is enclosed in a double-walled casing 10 separated from the storage tank by an air space, the space between the double walls being packed with heat-insulating material. Assuming the storage tank 11 to be empty and the motor 47 to be idle, water is poured into a filler pipe 19 until the storage tank 11 is full, a vent cock 38 being used to avoid overfilling. The pipe 19 terminates at the top of the storage tank and is vented by a vent pipe 25. When the motor is started suction is applied through a float valve tank 26 (of usual type) and pipe 29, to the header tank 8 and to a pipe 33 leading to the bottom of the storage tank. Siphonage is created and water rises up the radiator tubes, the pipe 33 and up the circulating pipe 50 until the circulating pump 48 is primed, and starts the circulation of water in the usual manner. When the water enters the float valve tank 26 the float valve closes a suction pipe 28, connected to the intake manifold of the engine. When the motor stops, the suction in the pipe 28 is replaced by sufficient ventilation from the carburetter to allow the float to drop and admit air to the system, thereby causing the water to drain by gravity into the insulated storage tank 11 where it is protected against freezing.

Title: Improvements in or relating to turbines
IPC: F02C3/073
Filed: 1941-04-08
Abstract: 585,330. Gas turbines. GRIFFITH, A. A. April 8, 1941, No. 4699. [Classes 110 (i) and 110 (iii)] [Also in Group XXXIII] In a gas turbine of the type in which many discs, independently mounted and, it may be, oppositely rotating, carry both turbine and aircompressor bladings, some of the discs carry also airscrew blades. Discs 17 of the low pressure part of the gas turbine carry air compressor blades 20, gas turbine blades 22 and air-screw blades 24. The air-screw blades operate within an annular chamber 11 open up-stream and discharging at 12 over the surface of the supporting aeroplane wing 10. Air is taken from the chamber 11 by two chutes 37, the open ends of which are turned to face the stream, and is delivered to an annular inlet chamber 38 of the air-compressor. Air is delivered from the high-pressure compressor stage 25 to a combustion chamber 32 and the products of combustion pass rearwardly through the turbine blades and discharge into the chamber 11. The chamber 11 is supported by hollow radial arms 13 and, itself, supports the front cowling 15 by hollow radial arms 14. Cooling air is taken into the arms 13 through holes in their leading edges and passes through the annular space 41 in the wall of the chamber 11 and the hollow arms 14 to ducts 45. These ducts, of which there may be eight, lie alternately with similar but longer ducts 46 around the finned exterior of the high-pressure turbine and the ducts are open to this exterior. Air passing out of a duct 45 on to the finned exterior enters the adjacent duct 46 and passes out. therefrom, at the part which extends forwardly of the ducts 45, again on to the finned exterior and escapes into the cavity of the cowling 15. From the cavity the air escapes to atmosphere through a hole 48 at the nose and this flow of air reduces the air drag on the cowling. A fan may be provided at the hole 48 to increase the flow. The plant may be started by means of an electric motor 49 and an air-compressor within the casing 32. Specifications 585,331, 585,333 and 585,335 are referred to.

Title: Improvements in or relating to the separation of mixtures of olefines and paraffins
IPC: C07C7/06
Filed: 1939-02-15
Abstract: 525,152. Separating olefines and paraffins. USINES DE MELLE. Feb. 15, 1939, No. 4970. Convention date, March 25, 1938. [Class 32] A process for separating mixtures of olefines and paraffins consists in distilling in the presence of liquid sulphur dioxide. The vapours evolved are rich in sulphur dioxide and paraffin, but practically free from olefine since the sulphur dioxide forms an azeotropic mixture with paraffins at all pressures. A mixture of propane and propene, for example from the rectification of cracking gas is sent from the tank 1 to the central portion of a distillation column 3 which is heated at the bottom and has plates provided with liquid sulphur dioxide. The apparatus functions at about 7 atm. pressure. The vapours arising in the column become progressively richer in propane. When they arrive at the top they have the composition of a propane-sulphur dioxide azeotropic mixture with 78 per cent. of propane and only a trace of propene. The liquid refluxing from the plates becomes progressively poorer in propane. Therefore a liquid mixture of propene and sulphur dioxide flows away in the pipe 4. The vapours from the top are condensed in the condenser 5. Some of the condensate is returned to supply the plates in the column 3 with sulphur dioxide. The rest is cooled to about -8‹C. in the brine condenser 7 and then sent to a separator 8 where two layers form, the lower one being almost pure sulphur dioxide and the upper one propane containing a little sulphur dioxide solution. The propane layer is sent through the pipe 10 to the column 11, the vapours from the top of which are returned to the brine refrigerator 7. Pure propane flows from the base and is obtained at 13. The sulphur dioxide from 8 is returned to the middle part of 3. The liquid mixture of propene and sulphur dioxide flowing away from the base of the principal column 3 is sent to an auxiliary column 14 where they are separated by reason of their different volatilities.
