Abstract: 364,383. Machine guns. CESKA ZBROJOVKA AKCIOVA SPOLECNOST V PRAZE, 31, VßclavskÚ nßm., Prague. Feb. 10, 1931, No. 4183. Convention date, Feb. 12, 1930. [Class 92 (ii).] For manually loading and unloading a machine gun of the Maxim type, a bellcrank lever R, P is provided which is pivoted to the gun casing, the arm P carrying a pin Y which engages a lever N fast with the usual crank pin F. For loading, a hook x on a lever X is moved into engagement with a toe n on the lever N to form a fulcrum for moving the pin F rearwards in the guide b in order to operate the cartridge-feed mechanism. The pin Y after riding up the lever N escapes over the top thereof to permit the return spring to restore the breech block to its closed position. The pin Y is spring-controlled and a bevel thereon enables it to re-engage the lever N when the lever R, P is returned by its spring U. The hook x is automatically disengaged from the toe n on firing. For unloading, the lever X is disengaged from the toe n and a simple rotation of the arm N is then effected by the pin Y. A spring pin Z on the arm P can be engaged with a groove m in the arm N to prevent, if necessary, a sudden return of the crank and to enable the breech block to be forced home by a forward movement of the lever R, P.

Abstract: 539,429. Casting sheets of film-forming materials. ROONEY, J. H., HAWTIN, P. R., and MACPHERSON, D. C. March 6, 1940, No. 4187. [Class 2 (ii)] Sheets at least one-hundredth of an inch thick are built up on a support travelling through a heated evaporative atmosphere, by the successive deposition of layers of a solution of a film-forming substance in a volatile solvent. A substantial part of the solvent initially present in each layer is removed by evaporation before the deposition of the next layer, and the bulk of the solvent is removed after the built-up sheet has been stripped from the support. The travelling support is preferably a continuous band of nickel or stainless steel having a highly polished surface. The solution may be a 20 per cent-35 per cent solution of cellulose acetate in acetone containing the desired content of plasticizer, and it may be made up with an excess of acetone which is boiled off under reduced pressure immediately before the solution is used. The temperature of the evaporative atmosphere and the speed of the band are reduced as the thickness of the built-up sheet increases. Specifications 396,723 and 538,024 are referred to.

Title: Improvements in the production of acrylic acid
Filed: 1954-02-16
Abstract: Acrylic acid is produced by the catalytic reaction of acetylene with carbon monoxide and water at raised temperature and under elevated pressure using an inert oxygen-containing organic solvent in excess and in the presence of a catalyst containing a soluble compound of a carbonyl-forming metal of the iron group and halogen either in free or combined form and in the presence of an activator consisting of a small amount of a soluble copper compound.  The catalyst is used in such small amount that it is homogeneously dissolved.  Preferred solvents are cyclic ethers such as tetrahydrofurane, -pyrane and 1,4-dioxane, and saturated ketones such as acetone, methyl ethyl and diethyl ketone.  Cyclic esters and amides such as butyrolactone or N-alkyl-lactones such as N-methyl and -ethyl pyrrolidones may also be used.  The preferred catalysts are nickel chloride and bromide. Carbonyls of metals of the iron group with free halogens, hydrogen halides, or other metal halides may also be used.  Preferred activators are copper halides but other water-soluble salts such as the sulphate, acetate or propionate may be used.  Powdered copper may also be added.  The preferred temperatures are in the range 150 DEG to 250 DEG  C. and the preferred pressures are in the range 20 to 60 atmospheres.  The process may be carried out batchwise or continuously.  In the examples acrylic acid is prepared by reacting acetylene with carbon monoxide using (a) nickel bromide as catalyst and copper chloride as activator; (b) nickel carbonyl and hydrogen bromide as catalyst and copper bromide as activator; (c) nickel chloride as catalyst and copper chloride as activator; (d) iron carbonyl and bromine as catalyst and copper bromide as activator; (e) nickel carbonyl, iron carbonyl and bromine as catalyst and copper bromide as activator; (f) cobalt bromide as catalyst and copper bromide as activator; and (g) nickel bromide as catalyst and copper chloride as activator.
