Title: Improvements in and relating to carburetting apparatus
IPC: F02M19/03
Filed: 1922-09-26
Abstract: 196,337. Ascough, H. N. Sept. 26, 1922. Spray carburettors.-A blast of combustion gases from the cylinders or exhaust branch for atomizing the fuel without exerting any entraining action thereon is delivered through a tube 7 arranged coaxially within the fuel nozzle 3 and projecting at 33 above the discharge outlet thereof. The tube 7 is adjustably screwed into the base 4 and fits closely another tube soldered at its lower end to the tube 3, the space between the latter tubes forming the fuel passage and terminating in a conical outlet between a cap 5 and the coned end of the tube 7. The nozzle delivers into the Venturi portion of a throttling sleeve 6 which controls on outlet port 20 and is. actuated by a lever 19 through a slotted arm 27 and pin 26 on rod 25. The combustion gases are led by a pipe 22 to a pressure chamber 14 which is connected by a second pipe to a union 9 on the tube 7. Air enters through ports 13 in casing 11, the flange 12 of which is secured to flange 10 on float chamber by studs. The upper part of the sleeve 6 may be replaced by a butterfly valve connected to the venturi portion or actuated independently thereof. The port 20 may lead to an upwardly-turned pipe with a horizontal flange instead of the vertical' flange 21. A mixing screen is provided at 30.

[A Specification was laid open to inspection under Sect. 91 of the Acts, July 9, 1935.] Drawings to Specification. [Class 39 (i)] A R÷ntgen-ray tube is supplied from a Tesla transformer tuned so that the tube is fed with high-frequency current in the form of impulses of potential above 150,000 volts and of such very short duration as compared with the intervening intervals of small or no potential that the average of the product of voltage and current remains low and the anti-cathode is not overheated even during continuous use and without cooling. The short duration is such that this average is not more than 3-5 watts per second with instantaneous impulses of 300,000 volts and 4 milliamps. The tube is fed without a rectifier. One end of the secondary of the transformer is connected to the anti-cathode and possibly also to earth or a large capacity or to one end of the primary coil, and the other end of the secondary coil is connected to the cathode. In a modified circuit, the anti-cathode is earthed and one end of the secondary coil is earthed. The apparatus may be portable and supplied from lighting mains or a Wimshurst machine. Electrons may be emitted from the cathode auto-electronically or the cathode may be heated by induction. The Specification as open to inspection under Sect. 91 comprises also R÷ntgen-ray tubes with cathodes heated by high-frequency induction, with one or more grids in the path of the electron stream and with the " oscillations" from the anti-cathode exposed to the action of a second anticathode.

Abstract: A composition comprises an oleaginous lubricant (preferably a mineral oil or grease, a vegetable oil or a synthetic oil) and a minor amount of atactic polypropylene or atactic polybutene-1 (preferably in a proportion up to 10% by weight of the composition).  The polymer is prepared by contacting the corresponding monomer with the reaction product of (a) an organo-compound of a non-transition metal of Group I, II or III of the Periodic System with (b) a transition metal halide.  In specific examples the polymer was prepared from the monomer in the presence of the reaction product of aluminium triethyl and titanium tetrachloride, the desired atactic polypropylene or polybutene-1 being extracted with ether and added to a low-viscosity mineral lubricating oil.  The polymer is said to improve the viscosity index and/or to depress the pour point of the lubricant. Specifications 783,578, 785,314, 799,465 and 804,085 are referred to.
