Filed: 1923-08-25
Abstract: 221,935. Chatwood Safe Co., Ltd., and Bruckshaw, H. S. Aug. 25, 1923. Metal-skeleton blocks. - Strong-rooms and similar structures are built up from a plurality of similarly-shaped units comprising metal frames embedded in concrete with edges adapted to interfit with edges of adjacent units. Figs. 1 and 2 show a frame F of which the part a interfits with the channel-shaped part b of an adjacent unit. The concrete part c is also moulded to interfit with the concrete part of adjacent units. The apertures d in the units are too small to admit the body of a man. Corner-pieces are similarly constructed by moulding the concrete on a bent metal frame. In the form shown in Figs. 6 and 7, the frame comprises two pieces of metal of I-cross section, the web of one being at right-angles to the web of the other so that the metal pieces interfit on assembling the units. The wall may be made up of a number of thicknesses, the units of one thickness breaking joint with those of the other thicknesses.
Patent GB-573888-A (GB)
Title: Improvements in or relating to methods of dry-spinning albuminous masses
IPC: D01F4/00
Filed: 1943-12-24
Abstract: A solution of milk-casein containing about 25 per cent of casein and having a pH value of about 9 is prepared for the dry-spinning of filaments or films, by subjecting it to homogenizing in a drum mill and then to de-aeration.  Preferably, the homogenized solution is filtered prior to the de-aeration. Homogenizing may be effected in a drum, in the interior of which steel bars are arranged.  As the drum is rotated, the steel bars beat the mass filling the space between them and knead it thoroughly.  The treatment may be continued for several hours. The solution which issues from the drum may be passed through filter cloths in a filter-press.  The homogenizing, filtering and de-aerating treatments are preferably carried out at 40-60 DEG C. In an example, a solution of casein in dilute caustic soda containing a small amount of oleic acid is homogenized in a rolling drum at 50 DEG  C. for several hours.  The solution is then filtered at the same temperature and deaerated by gradually reducing the pressure.  The solution is then forced into the spinning conduit and through the spinning nozzles.  In another example, the solution is homogenized in a rocking drum.

Title: Process for the manufacture of hydrolysed vinyl acetate/acrylic ester copolymers
Inventor: COLWILL WILLIAM
IPC: C08F220/10
Filed: 1957-07-10
Abstract: Process for preparing vinyl alcohol-acrylic ester copolymers comprises treating with an alkali metal hydroxide an aqueous alcoholic solution obtained by addition of a watermiscible alcohol to an aqueous dispersion of a copolymer of vinyl acetate and an acrylic ester containing not less than one part by weight of vinyl acetate per part by weight of acrylic ester, and thereby effecting hydrolysis of the vinyl acetate units of the copolymer. The acrylic ester may be an alkyl acrylate in which the alkyl group contains 1 to 4 carbon atoms, e.g. methyl acrylate, ethyl acrylate and butyl acrylate.  The aqueous copolymer dispersion may be prepared by emulsifying the monomers in an aqueous medium with the aid of partially hydrolysed polyvinyl acetate, adding thereto an aqueous solution of an alkali metal carbonate and an alkali metal persulphate, and polymerising. The watermiscible alcohol may be methanol, ethanol or butanol. Solutions of the copolymer products may be mixed with sulphonated methyl oleate, or wax emulsions comprising paraffin wax, light mineral oil, stearic acid and triethyanolamine, and used for sizing textile yarns.ALSO:Textile yarns, e.g. of regenerated cellulose, cellulose acetate, polyesters, polyamides or polymers of acrylonitrile, are sized with compositions comprising aqueous solutions of vinyl alcohol-acrylic ester copolymers prepared (see Group IV(a)) by treating with an alkali metal hydroxide an aqueous alcoholic solution obtaned by adding a water-miscible alcohol to an aqueous dispersion of a copolymer of vinyl acetate and an acrylic ester containing not less than one part by weight of vinyl acetate per part of acrylic ester, and thereby effecting hydrolysis of the vinyl acetate units of the copolymer.  Examples describe the sizing, prior to weaving, of (3) polyethylene terephthalate yarns with aqueous compositions comprising a hydrolised vinyl acetate-ethyl acrylate copolymer and (a) sulphonated methyl oleate and (b and c) emulsions of paraffin wax, light mineral oil, stearic acid and triethanolamine; and (4) nylon filaments with a size having the constituents specified in 3(b) and (c).

Title: Improvements relating to the production of acetic anhydride
IPC: C07C51/56
Filed: 1931-08-05
Abstract: The water accompanying acetic anhydride produced by the cracking of acetic acid is reacted with ketene produced from acetone to produce more anhydride.  A mixture of acetic acid and acetone may be passed over a vanadium oxide such as vanadium pentoxide, thus producing both ketene and acetic anhydride which are condensed together.  Or the acetone may be passed over a vanadium oxide and the acetic acid passed over a suitable catalyst, the vapours being then mixed and condensed together, or the ketene vapours may be passed into the acetic anhydride condensate.  The vanadium oxide catalyst may be prepared by treating pumice with a 2 per cent solution of vanadium sulphate and then heating to 600 DEG  C.  In an example the acetic anhydride is made by passing acetic acid vapour over pumice containing phosphoric acid, and ketene vapours from the acetone reaction preferably after first separating unchanged acetone, are passed into the anhydride condensate.
