Title: Method of and means for moulding articles
Inventor: WILLIAMS WILLIAM THOMAS
IPC: B28B7/00
Filed: 1961-03-08
Abstract: 984,677. Moulds. AERCRETE MOBILES Ltd. March 1, 1962 [March 8, 1961; Nov. 25, 1961], Nos. 8537/61 and 42250/61. A method of making articles from a settable liquid composition in a mould 15, 16 in which the composition is divided into separate articles by solid partitions 17, comprises removing the partitions 17 while the composition is still liquid, so that the composition flows together to form joints which when set are weaker than the articles, and setting the shapes to solid articles which are then broken apart from each other. In Fig. 1, the cells 18 can be filled with an aqueous concrete mix containing an aerating or foaming agent, in which case bubbles of gas collect at the surfaces of the partitions 17, so that when the partitions 17 are removed, the mix which flows into the vacated spaces has a high proportion of gas. Other moulds may be placed on top and the process repeated to form a stack of moulds which can be cured by steam. The partitions 17 may be of metal 1/ 1  inch thick and may be coated with foaming material or aluminium oxide. The partitions 17 may have double walls, open at the bottom and connected at the top to form a tube through which a foaming agent is supplied to fill the space vacated by the partitions 17. As in Fig. 6, more than one horizontal layer of articles may be produced in one mould, the composition being separated into layers, as the partitions 17 are withdrawn vertically, by pulling flexible tubes 28 through the composition. in horizontal planes, the trailing edges of the tubes 28 having holes for laying foaming material in the spaces created. Alternatively, the horizontal divisions between layers may be produced by pushing metal sheets through slots in a side wall of the mould, as the partitions 17 are withdrawn, and the slotted wall may have a facing of rubber (with slots) to prevent exit of the composition. Each cell 18 is provided with a filling device (Fig. 10) consisting of a flexible bag 39, filled with composition from a container 41, and of rollers 61, 62, 63 (which may be adjustable) on an endless chain 54 for discharging measured quantities of the composition through a slot 40 in a perforated plate 34 which fits over the mould. The plate 34 is welded to the partitions 17, and is shaped as at 35 to form frogs when moulding bricks. Compositions to which the invention can be applied are concrete mixes, metals and synthetic plastics. A piston-in-cylinder filling device may alternatively be used.

[Class 87 (ii)] [Also in Group XXIV]  The eccentric bush 14, which rotates with the eccentric arm 13 of the crankshaft 12 to impart vertical reciprocation to the slide 15, is secured to the eccentric arm by an annular lug and groove, or spigot and socket, engagement between the bush and a securing member 19. As shown, the securing member has flats which engage flats 20 formed on a reduced part of the eccentric arm, and an annular V-shaped lug 18 engages an annular V-shaped groove 17 in the bush, the member being tightened up by a screwthreaded locking collar 22. The lug 18 should not enter completely into the groove 17 ; for this reason, the lug may be a slightly oversize fit, or the angle thereof may be larger than that of the groove. The lug may be split radially, to facilitate wedging action. In modifications :-(1) The annulus of the lug may be interrupted to define arcuate lugs. (2) The lug may be on the bush and the groove on the securing member. (3) A plurality of concentric lugs may engage concentric grooves. (4) (Figs. 5 and 6).

Title: Improvements in or relating to process for the preparation of guanidino substituted fatty acids
IPC: C07C277/08

Abstract: Alpha guanidino-substituted fatty acids are prepared by admixing a guanidine salt, alkali metal hydroxide and an alpha halo fatty acid in an aqueous medium of not more than about 15 mols. of water per mol. of guanidine salt, allowing the reaction to proceed to completion, and separating alpha guanidino-substituted fatty acid from the reaction products.  Any alpha halo fatty acid may be used, for example chloracetic acid, alpha-chloropropionic acid and alpha bromoacetic acid.  The preferred guanidine salt is the hydrochloride, but the nitrate or sulphate may also be used.  Sodium and potassium hydroxides are preferred and may be added as a powder, as pellets or as a solution.  In examples: (1) one mol. of guanidine hydrochloride is admixed with one mol. of sodium hydroxide with stirring and one mol. of 50 per cent aqueous sodium hydroxide and one mol. of chloracetic acid are added over four hours at a temperature of 35-40 DEG  C.; the mixture is allowed to stand at 35 DEG  C. for 24 hours then diluted in water, agitated at 70-80 DEG  C. for one hour and then cooled, whereupon glycocyamine is separated by filtration; (2) crude guanidine hydrochloride is prepared by heating ammonium chloride and dicyandiamide and treated as in (1).  According to other embodiments, all of the alkali metal hydroxide is admixed with the guanidine salt and the halo fatty acid is added portionwise thereto, or the halo fatty acid and all the alkali metal hydroxide are first admixed and then added portionwise to the guanidine salt, or the guanidine salt, halo fatty acid and half of the alkali metal salt are admixed initially and the rest of the alkali hydroxide is added portionwise to the resulting mixture.  In general, the portionwise additions are made at a temperature between 0 DEG  and 60 DEG , preferably 30-40 DEG  C., with agitation over a period of 2 to 24 hours, preferably 4-8 hours, and then the mixture is allowed to stand for 8 to 30 hours at the same temperature to complete the reaction.
