Title: Processes for preparing a dispersion of an alkaline earth metal carbonate in an oil
Inventor: WINSOR PHILIP ALAN
IPC: C10L1/22
Filed: 1955-08-29
Abstract: A slurry of calcium, magnesium, barium or strontium alkyl carbonate is obtained by saturating with carbon dioxide a solution or suspension of the oxide or hydroxide in a lower aliphatic alcohol, e.g. methanol.  A dispersion of the alkaline earth metal alkyl carbonate may also be obtained by dispersing the metal in a lower aliphatic alcohol and saturating with carbon dioxide. Specific examples are given for the saturation of solutions of calcium and magnesium respectively in methanol with carbon dioxide.  The term "lower aliphatic alcohol" is defined as any organic compound containing not more than five carbon atoms and having a free hydroxyl group attached to a carbon atom, and includes monohydric, dihydric and polyhydric alcohols and alkyl ethers of such diols and polyols.ALSO:A dispersion of an alkaline earth metal carbonate in an oil is prepared by mixing a sol of the carbonate in a lower aliphatic alcohol with a solution of an oil-soluble primary or secondary aliphatic or cycloaliphatic amine or an N-acyl derivative of the amine in an oil and subsequently removing the alcohol from the mixture.  A solid product which is readily dispersible in an oil may be made by mixing the alcohol with a solution of the amine in the same or a different alcohol and separating the precipitate thus formed from the mixture.  Lower aliphatic alcohols comprise any organic compound containing not more than 5 carbon atoms and having a free hydroxyl group directly attached to the carbon atom, e.g. alkanols, glycols, glycerols, and alkyl ethers of such diols and polyols.  The amines preferably contain not less than 8 and not more than 24 carbon atoms in the molecule.  Examples are 1-decylamine, 1-hexadecyl amine, 1-octadecyl amine, oleyl amine and the N-methyl derivatives of such amines; naphthenic amines derived from naphthenic acids; and poly amines containing both hydroxy and amino radicals, e.g. ethylene oxide/polyethylene polyamine and epihalohydrins/ammonia or amino condensates.  Oils exemplified include residual fuel oils, benzene, toluene, mineral lubricating oil, synthetic lubricating oils, e.g. polysiloxanes, trioctyl phosphate, fluorocarbons, alkylated aromatic hydrocarbons or polymerized olefins, kerosene, gas oil, and castor oil.  The sol of an alkaline earth metal carbonate in a lower aliphatic alcohol may be prepared by dissolving the alkaline earth metal, oxide or hydroxide in a lower aliphatic alcohol, saturating the solution with carbon dioxide to form a dispersion of alkaline earth metal alkyl carbonate and subsequentially hydrolysing the said alkyl carbonate.

[Also in Group XVII] Boneless meat is pressed to shape in a trough  3 by a cover 8, carried by arms 11, which is forced down on it by air pressure, one end of the trough being closed by an end pressing plunger 21 and the other end by a closure plate 24 carrying a nozzle 26. The trough 3 is mounted on a table 2 to receive or be exchanged for troughs of different size, the cover 8 also being exchangeable to fit the trough in use. After pressing, the plate 24 is slid aside to allow the meat to be forced through the nozzle and into a casing of fibrous or plastic material mounted thereon. The meat then drops on to a platform 52, Fig. 7, and is passed to a closure device where the free end of the plastic cover is gathered together and clipped by a U-shaped clip in dies 60, Fig. 9, where the lower die 58 is forced up by a lever 68 to close the dies 60 around the clip. The clips are supplied from a magazine 77. The casing is gripped for sealing between jaws 90, 91, Fig. 12, closed by a hand lever 95 and operation of an air cylinder 87 moves the gripping device away from the dies and tightens the casing around the meat. The casing is first open ended and is slid over a sleeve 27, Fig. 1, on the nozzle and is later sealed as above by a clip at each end, the meat being reversed for the second clip. If the meat is to be boiled or steamed it is forced from an appropriately shaped trough and cover-plate into an open-ended rectangular tubular metal case (Figs. 15 and 16, not shown), the ends being covered by plates while being cooked and one end being compressed inwards by a spring to take up shrinkage. When the meat is to be smoked it is inserted in an openwork cage. The meat mass may be inserted in flexible casings before insertion in the metal cases or cages.

Title: Rifle grenade
IPC: F42C1/04
Filed: 1953-09-09
Abstract: 733,399. Ammunition projectiles and fuzes therefor. SOC. ANON. BELGE DE MECANIQUE ET D'ARMEMENT. Sept. 9, 1953 [Sept. 15, 1952], No. 25004/53. Class 9(1). A rifle grenade containing a hollow charge 3 and fitted with a ballistic cap 1 and a tubular tail 5 equipped with stabilising fins 6 is provided with a base fuze housed in a chamber 7 intermediate the grenade body and the tail 5. The chamber 7 has an extension 9 around which is an annular space 10 to receive a firing tube 11, Fig. 2, attached to the rifle. The extension, which has a thickened base 12, houses a detonator 8 above which a hollow member 15, closed by an obturator 16, is held by balls 24 housed in a fixed sleeve 23. The balls are locked in position by a safety device comprising two annular members 17, 19 held apart by a spring 18. On discharging the grenade, the annular member 17 sets back due to inertia so that claws 13 enter a groove in the member 19 to lock the members together. As the grenade decelerates the locked inertia members move forward together guided by slides 21 projecting from the member 19 into zig-zag grooves 22 in the sleeve 23. The balls 24 then escape freeing the detonator, which then moves forward until the obturator 16 contacts a striker 14 resting on a cushion 26, e.g. of paraffin wax, supported by the cavity liner 4. On impact, the striker 14 penetrates through the obturator 16 and initiates the detonator 8 to fire the charge 3. In a modification the inertia member 17 surrounds the member 19 and under the action of a spring locks a ball in position to secure the member 19 until set-back of the outer member releases the ball. In a further modification a single inertia member locks the balls 24, the member being provided with two grooves, each having two branches. Fixed slides extend into the grooves to give the inertia member a reciprocating motion and delay arming of the fuze as in Specification 620,875. Reference has been directed by the Comptroller to Specification 620,875.
