Title: Improvements in high-pressure metal-vapour electric discharge devices
IPC: H01J61/073
Filed: 1937-05-20
Abstract: 491,176. Discharge-lamp electrodes. GENERAL ELECTRIC CO., Ltd., FRANCIS, V. J., and PIRANI, M. May 20, 1937, No. 14069. [Class 39 (i)] In high-pressure metal vapour discharge devices wherein the main discharge commences on a starting electrode and transfers to an associated running electrode such as described in Specifications 444,545 and 472,658 the running electrode of tungsten has a supply of thoria to improve its thermionic emissivity the starting electrode being coated or constructed with a supply of alkaline earth oxide ; at least one of the main electrodes is so formed and if the supply is A.C. both are constructed in this manner. An auxiliary discharge electrode may be used to start the discharge. The starting electrode 2 is a rod 3 of alkaline earth silicate surrounded by two tungsten helices 4, 5 ; the running electrode consists of the turns 1 of tungsten coated with a suspension made by ball-milling thoria and water with tungsten powder. The electrodes are degassed by external heating both when the envelope is evacuated and afterwards in a hydrogen filling and by bombardment, the tungsten and thoria coating sintering together. In a modification the running electrode is a rod coated with a suspension as described above the rod being enclosed by helices in which a rod of alkaline earth silicate is held. In a further construction a tungsten helix at one end surrounds the alkaline earth silicate rod to form the starting electrode and its other turns have wound thereon a fine wire helix these turns being coated with the thoria tungsten suspension ; the ends of the main helix are led out of the envelope so that a current for degassing may be passed through the helix. The dimensions are given of tubes in which the three electrode constructions as set out can be used. When the device is on a D.C. supply the anode may have a thoria supply to keep the electrode at lower temperature than if tungsten only were used. Specifications 482,012 and 486,138 also are referred to.

Title: Process for the alkylation of paraffin hydrocarbons
IPC: C07C2/62
Filed: 1937-05-25
Abstract: Normal paraffins having 3 or 4 carbon atoms are alkylated to produce liquid hydrocarbons of gasoline boiling range by treatment with mono-olefines having 3 or 4 carbon atoms at temperatures of approximately 20 to 75 DEG  C. in the presence of aluminium chloride and a minor amount of hydrogen chloride, a molecular excess of the paraffin relative to the olefine being maintained during the reaction.  The aluminium chloride may be employed alone or on carriers.  The paraffin, e.g. n-butane, may be mixed with the aluminium chloride, and the olefine such as isobutylene, together with a small amount of hydrogen chloride, introduced, sufficient pressure to maintain a liquid phase being imposed. Alternatively, the liquid olefine may be mixed with a molecular excess of liquid paraffin and with aluminium chloride, hydrogen chloride being introduced to effect the alkylation.  The upper layer is decanted, and fractionated to recover the gasoline fraction.  The process may be effected continuously by passing the liquid paraffin, olefine mixture with suspended aluminium chloride, and hydrogen chloride through a tubular reactor at a temperature within the specified range.  Generally the molecular ratio of paraffins to olefines is about 3 to 1.  In examples: (1) n-butane and propene in weight ratio of 3 to 1 are forced into an autoclave containing 1 part by weight aluminium chloride and 0,1 part hydrogen chloride at 65 DEG  C. and 150-200 lb./sq. in.; (2) a 3 to 1 mixture of propane and propene is forced into a vessel containing 2 parts aluminium chloride and 0,2 part hydrogen chloride at 70 DEG  C. and 600 lb./sq. in.
