Title: Improvements in or relating to gas fires provided with lighters
IPC: F24C3/10
Filed: 1936-07-08
Abstract: 477,959. Igniting gas fires. MAIN, Ltd., R. & A., and ROBINSON, H. N. July 8, 1936, No. 18961. [Classes 75 (iii) and 126] An igniter is disposed in a space above, and in free communication with, the upper ends of the tubular radiants of a gas fire so that the flame initiated in the space lights back simultaneously through all the radiants to the burner nozzles. As shown in Fig. 1, the friction-wheel 21 of a pyrophoric igniter is secured on an operating shaft 22 mounted in a casing 25 secured by nuts 33, 34 and washers 36, 37 to the ornamental upper part 16 of the front wall 14, the lower open end of the housing 27 being in register with a hole 38 in the upper part 17 of the flue. The flint 29, Fig. 5, is pressed against the wheel 21 by a spring-pressed plunger 31 projecting through the screw-cap 32 of the flint-tube 28 to indicate the length of the flint. The back wall 10, side walls 11 and lower part 12 of the flue are formed from one piece of sheet metal. The front end 18 of the flue part 17 forms an inner canopy and has welded to it a strip of metal 13 forming an outer canopy. In the gas-fire shown in Fig. 2, the back wall 10, side walls 11 and inner canopy 18 are cast in one piece and the casing 25 of the igniter is screwed into, or formed integral with, a panel 40 secured in a recess 41 in the front wall. Specifications 322,838, [Class 126], and 385,357 are referred to.
Patent GB-827199-A (GB)
Title: Compass direction indicating system
IPC: G01C19/36
Filed: 1956-06-19
Abstract: 827,199. Direction indicator systems. BENDIX AVIATION CORPORATION. June 19, 1956 [June 30, 1955], No. 18979/56. Class 40 (1). In a direction indicator system for aerial navigation, indication is derived from a magnetic compass, or from a directional gyro, compensation being provided for drift, or from the gyro corrected by the magnetic compass. As shown, when a selector switch 36 having five ganged three-position contact arms 31-35 is in its uppermost position, the system is operated by a magnetic compass 10, preferably of the flux gate type, connected to the energized rotor 12 of a selsyn transmitter 11, rotation of which upon deviation from course produces in the rotor 16 of a selsyn receiver 15 a signal which is fed via a pre-amplifier 37 to an amplifier 38, the output of which is applied to a motor 39 which rotates the rotor 16 and an indicator dial 17 until the rotor 16 is in its null position; motor 39 also drives autopilot apparatus 41 and a transmitter 42 for remote indication. The output from a rate generator 43 driven by the shaft of motor 39 is dropped across a potentiometer resistor 44, a point on which is connected to the amplifier 38 to maintain the speed of the motor 39 constant. When the selector switch 36 is in its lowest position the system is operated by a directional gyro 18 through selsyns 20 and 23, a signal from the rotor 24 of the latter being fed to a gyro amplifier 45 whose output is transmitted to the motor 39. Gyro drift is compensated by the angular displacement of the stator 22 of the receiver selsyn 23 by a motor 62, fed through amplifier 38 with a signal from a potentiometer 50, the position of the pointer 51 on potentiometer resistor 49 being determined by manual operation of a knob 54 associated with a latitude scale 56, or of a knob 59, the speed of motor 62 being kept constant by utilizing the output of a rate generator 70. The stator 22 may be manually set by operation of a knob 67. When the selector switch 36 is in its intermediate position the system is operated by the gyro 18, stabilization being provided by the magnetic compass 10, any error signal produced in selsyn receiver rotor 16 due to non-correspondence of the positions of transmitter rotors 12 and 19 being fed after amplification to motor 62 which displaces gyro selsyn receiver stator 22. In an alternative embodiment (not shown) maintenance of motor 62 at a constant speed is effected by a mechanical escapement, the rate of drift compensation applied to stator 22 being determined by the position of the roller in a disc and cylinder drive between the escapement and the stator 22, said position being set in accordance with latitude. Specification 550,399 is referred to. Reference has been directed by the Comptroller to Specification 747,207.

Abstract: 147,230. Otto & Co., Dr. C. Aug. 15, 1916, [Convention date]. Coke ovens.-In a vertieal-flued coke oven having flues connected in pairs and regenerators running longitudinally beneath the oven chambers, the air is always admitted to the regenerators at the side of the bench and the waste gases are exhausted to the main flue at the other side. Beneath each oven are two regenerator chambers, each divided into compartments 7 correspending in number with the pairs of flues 3, 4, and beneath each regenerator chamber is a flue 9 having at one end an air-inlet valve 11, and at the other a connexion through a reversing- valve 13 with a main flue 15.

Patent GB-422139-A (GB)
Title: Improvements in the manufacture and production of trimethylamine
Filed: 1933-07-08
Abstract: Trimethylamine is separated from mixtures thereof with ammonia by distillation in the presence of a third substance which forms with ammonia an azeotropic mixture of lower boiling point than the azeotropic mixture of trimethylamine and ammonia, but does not form a ternary azeotropic mixture with trimethylamine and ammonia. Suitable substances are low-boiling aliphatic hydrocarbons and ethers.  The distillation is preferably effected at a raised pressure, e.g. at the vapour pressure of the mixture at atmospheric temperature, but distillation may also be effected at atmospheric or reduced pressure. When the boiling point of the third substance differs considerably from that of trimethylamine, an excess of the third substance may be added, so that all the ammonia may be removed as azeotropic mixture and the excess of third substance then distilled off.  When the boiling point of the third substance is close to that of trimethylamine, the amount of substance added is preferably rather less than is necessary to remove all the ammonia as azeotropic mixture, the remainder of the ammonia being removed as ammonia-trimethylamine mixture.  Examples are given describing the distillation of ammoniatrimethylamine mixtures in the presence of n-butane, isobutane, and dimethyl ether; the use of n- or iso-butylene as the third substance is also mentioned.  When dimethyl ether is used, the azeotropic mixture can be used, with or without addition of ammonia and methyl alcohol, for the catalytic manufacture of methylamines.ALSO:Trimethylamine is separated from mixtures thereof with ammonia by distillation in the presence of a third substance which forms with ammonia an azeotropic mixture of lower boiling point than the azeotropic mixture of trimethylamine and ammonia, but does not form a ternary azeotropic mixture with trimethylamine and ammonia.
