Abstract: 1,097,424. Cathode materials and processing. GENERAL ELECTRIC CO. March 19, 1965 [April 16, 1964], No. 11815/65. Heading H1D. A dispenser cathode is produced by first forming pellets of an activator material, consisting of a solid solution of Ba 3 WO 6  and Ba 2 SrWO 6 , by firing a mixture of barium and strontium carbonates and tungsten trioxide; finely dividing the pellets and mixing with a finely divided refractory metal e.g. tungsten, and a source of zirconium or hafnium; pressing the mixture into a cohesive form and firing in a reducing atmosphere; and finally removing a surface layer to expose a low work function surface of a porous material formed of 88% to 94% of the refractory metal, 5% to 12% of a single-phase barium strontium tungstate solid solution of composition Ba 3 WO 6 .Ba 2 SrWO 6 , and less than 1% of zirconium or hafnium. The activator material is prepared by wet milling barium and strontium carbonates with tungsten trioxide, firing the dried and compressed powder in air at a temperature exceeding 1400‹ C., and powdering the resultant material. The latter is mixed with powdered tungsten to form the porous matrix of the cathode, and powdered zirconium hydride to form the reducing agent for the activator, and is thereafter ball-milled, pressed at pressures of between 40 and 90 tons per square inch, and sintered in pure hydrogen at 1350‹ to 1900‹ C. Finally, a suitably shaped emitting surface is formed in the sintered cathode body by removing a surface layer with a high-speed cutting tool. The preferred composition is 88% tungsten, 0À75% zirconium hydride, and 11-“% activator. Preferred particle sizes and times of milling and of heat treatment are given.

Title: Improvements in or relating to the production of aliphatic hydrocarbons
IPC: C07C1/20
Filed: 1940-07-18
Abstract: 543,327. Hydrocarbons. DU PONT DE NEMOURS & CO., E. I. .July 18, 1940, No. 11843. Convention date. July 19, 1939. [Class 2 (iii)] Long chain aliphatic saturated or unsaturated hydrocarbons are obtained by heating a primary aliphatic alcohol or aldehyde having more than 8 carbon atoms in the chain, in the liquid phase and in the presence of a dehydrogenating catalyst. The preferred re-action temperature is between 225‹-250‹ C. The pressure may be atmospheric or higher. Catalysts mentioned include finely divided iron, nickel and cobalt. If it is desired to operate at atmospheric pressure, a release of the generated gas is necessary, otherwise in a closed system a pressure of 800-900 1b. per square inch is produced. In some cases, particularly at atmospheric pressures, hydrogen and carbon monoxide are eliminated simultaneously with the formation of a hydrocarbon containing one. less carbon atom than the original aldehyde but with terminal unsaturation. In examples, (1) pure octadecanol-1 is heated to 225‹-250‹ C. in the presence of 10 per cent. of nickel catalyst under atmospheric pressure, to produce a mixture of heptadecene-1 and heptadecane. (2) Pure tetradecanol-1 is heated in a closed autoclave with a nickel catalyst under 450-500 1b. per square inch pressure of hydrogen for 2¢ hours at 250‹ C. to.give tridecane. (3) Commercial octadecanol-1 is treated in a stainless steel autoclave with reduced nickel-on-kieselguhr under 300-350 lb. per square inch of hydrogen for 4¢ hours at 250‹ C. to give on distillation of the products pure heptadecane. (4) Pure octadecene-9-ol-1 is heated in an open flask with a nickel catalyst from 215‹-270‹C. during 4 hours. A rapid evolution of gas takes place and heptadecene-8 is produced. Other starting materials mentioned include such primary alcohols or the corresponding aldehydes as decanol-1, dodecanol-1, tetradecanol-1, linoleyl alcohol, eleostearyl alcohol, 2-heptyl-heptanol-], 3-propyloctanol-1, and pentyl-2-nonene-2-ol-1.

Filed: 1945-05-11
Abstract: 591,529. Automatically-adjustable couplings. CLEVELAND, F. J. (Bendix Aviation Corporation). May 11, 1945, No. 11900. [Class 80(ii)] [Also in Group XXVII] In. an automatically - adjustable coupling timing ignition in a magneto drive, the driving and driven members are both connected to an intermediate element, one by means such that axial movement of the element causes relative circumferential movement between the members, and the other by centrifugal means which move the element axially first in one direction and then in the other as the speed of rotation increases, whereby the spark is advanced with increase of speed over one speed range and retarded with speed increase over a higher speed range. As shown, a driving shaft 54, Fig. 1, and the shaft 53 of a magneto rotor 52 are. connected to-a flanged intermediate sleeve 56 by helical and straight splines 57, 58 respectively. A bob weight 60, straddling the sleeve 56, hinges about pivot pins 65, Figs. 2 and 3, mounted on the flanged end 61 of the sleeve 56, and has pivot pins 69 at its free end engaging links 62, 63 themselves hinging about pivot pins 70 mounted on the end plate 64 of the rotor 52. The centrifugal action is resisted by springs 72, 75 acting between the pins 69 and supports 74, 76. As the bob 60 moves outward with increasing speed, the sleeve 56 is moved, first to the left, and then to the right when the pins 69 pass the plane containing the pins 65, 70. The spring 75 comes into action only when a lost motion connection 77 with the pin 69 is taken up, which preferably occurs when the latter reaches the plane of the pins 65, 70; and the spring 75 may be strong enough to cause appreciable dwell at this point. A similar but reversely mounted centrifugal assembly, 60<1>, 62<1>, 63<1>, is provided on the opposite side of the sleeve 56. The subjectmatter described is the same as part of the, subject-matter comprised by Specification 591,528, which is referred to, but the claims differ.

Title: Improvements in the manufacture of moulds for use in the shell moulding process
IPC: B22C23/00
Filed: 1954-04-26
Abstract: 753,697. Moulding-processes. WILLIAMS, H. K. April 26, 1954 [May 7, 1953], No. 12065/54. Class 83 (1). A shell-moulding process comprises building up on a heated pattern a thin layer, by the use of a wet mixture of a relatively fine refractory material and a bonding agent, and then adding a quantity of relatively coarse refractory and a binder to complete the shell. The fine refractory, e.g. silica flour of 200 mesh or finer, may be in a slurry made with a solution of thermosetting resin applied by spraying, or in a wet or dry mixture with a resin, applied by dumping, slinging or blowing. The layer is not more than 20 thousandths of an inch thick. In an example, a slurry is made from four pints of a 20 per cent solution of a two-stage phenol formaldehyde resin in methylated spirits, two pints of water and enough ammonium hydroxide to ensure no residual precipitate, mixed with ten pounds of silica flow, there being 8-10 parts by weight of resin to 100 parts by weight of silica flour. The slurry is sprayed on to a heated pattern which has been coated with a release agent, and the mould then completed by dumping a mixture of silica sand of 20-80 mesh mixed with 5-7 per cent by weight of the mix of phenol formaldehyde resin. For the primary layer other resins such as urea or melamine resins, other solvents such as industrial alcohol or methanol, and other refractories such as zircon flour, alumina and magnesite may be used. For magnesium-casting moulds “-1 per cent of the silica flour may be replaced by boric acid, and for iron or steel casting, ferric oxide may be substituted for about 5 per cent of the silica flour. About 2-3 per cent of finely divided graphite may be substituted for the silica flour. For the backing layer crystobalite, zircon or olivine sands, sillimanite or mullite, or a mixture thereof may be used.
