Title: Improvements in or relating to the extraction and refinement of alumina
IPC: C01F7/38
Filed: 1931-04-21
Abstract: A process for the production of pure crystalline alumina in which aluminous materials such as bauxite are subjected to a reducing smelting process with sulphur compounds, such as iron sulphide, and coke is characterized in that the liquid slag thus obtained, after being drawn off from the iron alloy, is transferred to a refining furnace wherein it is allowed to cool, say to 1400 DEG  C., till crystallization of the alumina takes place. After reheating, say to 1900 DEG  C. and allowing to stand, say for ten minutes, refining means, viz. iron pyrites, iron and subsequently coal, are added. After say ten minutes, the refined upper layer is withdrawn, allowed to solidify and washed with acid, if necessary, or treated with water, steam, &c., as in Specification 232,549, [Class 1 (iii), Oxides &c., Metallic].  The sludge formed during this treatment may be dried, briquetted and added to the second refining operation with the necessary sulphur compounds.  The waste slag may be added to the original charge, or treated according to the present method separately or admixed with the sludge briquettes.

Title: Improvements in or relating to clockwork-operated fuses for shells and the like projectiles
IPC: F42C9/04
Filed: 1924-05-16
Abstract: 219,944. Tavannes Watch Co. Soc. Anon. Jan. 23, 1924, [Convention date]. Projectile fuzes.-Clockwork fuzes are provided with a rotatable internallytoothed crown member adapted to be set in accordance with the time desired, in combination with a reducing gear for driving the member from the driving shaft of the clockwork. The detent 4 of the spring striker 1 is held before the projectile is discharged by means of a bolt 9 which sets back by inertia at the moment of discharge. The detent is held during the flight of the projectile by the crown member 11 which at the appointed time brings a notch 23 opposite the end 24 of the detent, whereupon the detent releases the striker by swinging out about its pivot 6 under the influence of centrifugal force and a spring 7 acting on a pin 8 on the detent. The crown member 11 is guided between rollers 15, 16, and is provided internally with a circle of teeth 17 in mesh with a pinion 18 connected by pinions 20, 21 to the driving shaft 22. The bolt 9 in conjunction with a stop 26 on the crown member serves also to prevent this ring from completing before the projectile is discharged the forward movement necessary to release the detent. The detent, instead of releasing the striker directly, may release a sleeve which in turn releases balls normally holding the striker. Specification 234,513 is referred to.

Examples describe the hydrogenation using a nickel catalyst of Canbra, corn, soybean, rapeseed and coconut oils and mixtures thereof. Margarines containing partially hydrogenated oils of the invention, milk powder, salt and monoglycerides, and an ice cream fat composition of coconut oil and partially hydrogenated oil are also described.
