Title: Improvements in or relating to apparatus for darning woven or knitted articles or fabrics
IPC: D04B17/00
Filed: 1922-02-23
Abstract: 187,178. Kingsmill, H. L. Feb. 23, 1922. Darning.- In a darning apparatus, diagonally corrugated work-holding plates E, F are pressed together by a spring H and slide in a transverse guide way B. A needle D which passes through suitable slots in the work plates is carried by a needle-bar C. The plate F has ratchet teeth on its under-side engaged by a panel M which is turned on its pivot to feed the work when a pin N, on the return stroke of the needle-bar, engages an inclined edge M<4> of the pawl. The pawl is returned by a spring and on the forward stroke, of the needle-bar an upwardly inclined surface M<3> of the pawl depresses the pin N out cf effective engagement with the pawl. The needlethread loop is engaged by a curved and pivoted looper J which is turned away from the needle during its forward stroke, by the engagement of a projection K on the needle bar with a lever arm J<2>, is released shortly after the commencement of the return stroke and then moved to engage the thread loop by a spring J'. The concatenation of the thread-loops is assisted by a spring O and is effected around pins P on the work-plate F so that when the work is removed loops are left at the side of the darn to provide for shrinkage.

Title: Improvements relating to toy figures and playthings
Inventor: SENIOR HENRY
IPC: A63H9/00
Filed: 1956-02-23
Abstract: 821,529. Moulding toys from polyurethane. BRITISH XYLONITE CO. Ltd. Jan .23 1957 [Feb. 23, 1956], No. 5624/56. Class 87(2). [Also in Group XV] A shaped body, e.g. a toy figure or ball, has an outer flexible covering or skin and an internal shaped filling of a polyester foam. The filling, obtained by mixing a polyester resin with an isocyanate, may be moulded in situ in the covering or be moulded to shape externally of the covering or skin and subsequently inserted therein. The covering may be P.V.C., rubber or polyethylene but if woven fabric is used it is made impervious to, or is protected from, the foam by treatment or provision of a suitable lining. Alternatively, the covering or skin may be applied to a moulded body of polyester foam as a film. A core of malleable metal wire may be embedded in the foam filling of a toy figure which may thus be set in various postures. In Fig. 1, a hollow torso formed of a vinyl polymer has a flanged neck opening 7 through which ingredients are introduced into the torso where they react to produce the polyester form. The limbs of the toy are hollow and each has a headed spigot 3 for engagement in a recess 4 in the torso. In a modification, Fig. 2 (not shown), the limb spigots form closures for torso openings in which they engage. The head and the limbs may also be filled with polyester foam either before or after being attached to the torso. Fig. 3 shows a doll in which the limbs and torso are inseparable and a wire core 18 is embedded in the foam filling. A separate limb 2, Fig. 4 is provided with a springy wire element 24 which is bent into a ring 23 and a trailing portion 24 ; the ring maintains the element in position which becomes embedded in foaming polyester resin when the resin penetrates through an aperture 21 in the limb spigot during filling of the torso. In Fig. 5, an outer covering 25 for a toy animal head is formed by slush moulding, P.V.C. or other plastic mix being charged into the mould 26 and partially cured. After pouring out the excess mix and leaving a thin film on the moulding surface the constituents to produce the polyester foam are mixed and poured into the mould. At the same time heat is applied to finish the curing of the covering, the setting of the foam meanwhile taking place. In producing the foam, specified proportions of a polyester, a tetriary amine catalyst, an emulsifying agent and water are first mixed. A diisocyanate is then added to the preliminary mixture and the final mix stirred at high speed for 5-10 seconds before passing it into the mould or covering. According to the Provisional Specification, the covering may be of thin acetate, and core-forming elements or wires may be interlinked at joints between parts of a figure to allow for turning or swivelling. On making a figure, a malleable iron wire insertion is positioned by spiders or discs.

Patent GB-189706-A (GB)
Title: Process for the production of finely subdivided solid substances
IPC: B01J13/00
Filed: 1922-02-27
Abstract: Substances are obtained in a high degree of dispersion by heating in a current of air, carbonic acid &c., to such a high temperature as to produce vapours substantially free from fumes, and condensing the vapours to fumes, which are then precipitated electrically.  The products are suitable for use as catalysts for gas reactions, as adsorbents for clarifying liquids, as precipitants for dissolved substances, as mineral pigments, as opalizing agents, and as medicines.  A chemical change may be effected during the process. Mixtures may be volatilized and condensed together.  Metallic tin may be melted in an electric arc furnace and blown with air.  The products are subjected to a whirling action in a large chamber and then pass to the electric precipitator.  Tin oxide thus obtained gives a milky colloidal solution with N/50-N/100 ammonia or hydrochloric acid solution, and is capable of precipitating phosphoric acid from nitric acid solution.  It is adapted for use as an opalizing agent for glass or enamel.  Bismuth oxide similarly got from metallic bismuth is applicable to China-painting.  Catalytic substances such as nickel and iron oxides, in conjunction with carriers such as oxides of aluminium, titanium, tin, silicon, or vanadium may be obtained by blowing electrically-fused ferro-titanium, ferro-vanadium &c., and treating as above described. Colloidal subdivision of the oxides produced occurs on mere treatment with water.  After reduction by hydrogen, the iron products are pyrophorus if they contain more than 30 per cent of the metal. Nickel catalysts need not contain more than 20 per cent of metal. Specification 189,132, [Class 1 (iii), Oxides &c., Metallic], is referred to.ALSO:These are obtained in a high degree of dispersion by heating the metals in a current of air to such a high temperature as to produce vapours substantially free from fumes, and condensing the vapours to fumes, which are then precipitated electrically.
