Title: Improvements in or relating to stencils
IPC: B05C17/06
Filed: 1945-05-10
Abstract: 582,274. Stencil plates. STANDARD TELEPHONES & CABLES, Ltd., and DELAMARE, A. O. May 10, 1945, No. 11726. [Class 100 (ii)] Characters are engraved into the face of a plate 1, Fig. 3a, to a certain depth as shown in Fig. 3b, the plate 1 being thicker than the final stencil, or having a backing plate secured to it. A shallow groove 6 is then cut across an enclosed portion 5 of a character, and a tie-strip 7 inserted therein, which may be soldered or otherwise attached to the portion 5 or to the main portion of the plate or to both. Alternatively, the groove 6 may be dispensed with and the strip 7 fixed across the surface of the character. The back face of the plate is now cut off to such a depth that the characters extend through the plate, or if a backing plate was used this is removed with the same result.

Abstract: 883,159. Aircraft arresting devices. FONDEN, P. B., and WALANDER, K. O. T. April 4, 1960 [June 3, 1959], No. 11800/60. Class 4. An arresting device for aeroplanes consists of a net comprising two vertically spaced horizontal wires interconnected by a plurality of vertical ropes of one length and by additional ropes of greater length, so that, should some of the shorter ropes break, the longer ones contribute to the arresting of the aircraft. It may be desirable not to have any vertical ropes in the middle portion of the net, since, for particular types of aircraft, this will ensure that the cabin is protected and the cabin doors do not become obstructed.

Title: Improvements in or relating to the production of vinyl derivatives
IPC: C08F8/28
Filed: 1934-04-19
Abstract: Condensation products of a polyvinyl alcohol and formaldehyde or a polymer thereof are manufactured in the presence of hydrochloric acid as catalyst in an amount adjusted in accordance with the nature of the starting material and the reaction temperature to yield final products that are soluble in methylene chloride and that give a viscosity greater than 37 seconds Engler when measured at 15 DEG  C. as a 2 per cent solution in a mixture of four volumes of methylene chloride with one volume of absolute alcohol.  In an example, a polyvinyl alcohol of which a 4 per cent aqueous solution has a viscosity of 64 seconds Engler at 15 DEG  C. is condensed with trioxymethylene in aqueous hydrochloric acid solution containing 8,8 per cent of hydrogen chloride when working at 20 DEG  C. or 15,5 per cent at 60--80 DEG  C.  If the polyvinyl alcohol be replaced by one having a viscosity of 97 seconds Engler under the conditions specified, the percentage of hydrogen chloride necessary is 11--12 at 20 DEG  C.  Specifications 337,806, [Class 2 (iii)], and 351,082 are referred to.

Abstract: 233,720. Redfern, C. G., (Hartstoff-Metall Akt. Ges. (Hametag)). May 7, 1925. Granulating. - Molten metal from a container 7 is fed into the path of a rapidly rotating beater 8 mounted on a rotary shaft 9 inside a closed rotating drum 1 mounted on a shaft 2 and containing a liquid 5 such as tetralin, paraffin &c. which has no action on the metal. The molten metal is shattered by the beater 8 and caused to fly into the liquid 5 which owing to the rotation of the drum 1 mounts up the side of the latter as shown. The metal granules are directed during their fight by the rotating liquid and travel to the bottom of the drum 1 in a spiral path as indicated. To prevent oxidation of the molten metal before it reaches the beater 8 the space above the liquid 5 may be filled with an inert gas such as carbon dioxide. The beater 8 may be in the form of a flat circular broom with radial bristles or rods, and the arms of the beater or bristles of the broom may be coated with a liquid such as tetralin to prevent the metal adhering thereto.

Abstract: 183,579. Hewitt, C. K. April 26, 1921. Flax-pulling machines.-A flax-pulling machine is provided with a transverse pair of jaws of which the forward jaw is adapted to extend forwards and over a breadth of flax and then to move downwards to grip this breadth against the rear jaw. The jaws are carried by front and rear members pivoted on a shaft 3, and each consisting of a pair of spaced-apart bow-shaped arms connected at their lower ends by a gripper bar 6. The arms of the front member are articulated, each being formed in three parts 7, 8, 9 operated by a system of levers 10, 11, 12, 13 from a cam 14 on the shaft 3. One of the arms of the member 5 is provided with a projection 18 carrying a roller 17 engaging a cam 16 on a shaft 15 driven from a countershaft 36 and driving, through a train of wheels 40, the shaft 3. The countershaft 36 is driven by chain-gear from one of the land wheels of the machine. The shaft 15 carries an arm 19 provided with a roller 20 engaging in a slot 21 in a plate 22 secured to the part 9 of one of the front members. The rear jaw, during the gripping of the flax, is spring controlled, being pulled forwards by a spring 26 secured to a lever 27 operated by a cam 31 on a shaft 32. In working, the gripper arms are opened to the extent shown in Fig. 3 by the rotation of the cam 16 and the arm 19 on the shaft 15, the cam 14 simultaneously operating to lift the front jaw to clear the crop; the front jaw is then lowered until it meets the rear jaw which is advanced by the action of the cam 31, the articulated members of the front jaw being then locked by a cam-operated toggle device : the jaws next swing to the rear, pulling the flax and carrying it over a platform 49 and finally releasing it. To ensure the flax being laid properly on the platform, the rear jaw continues its rearward movement after the flax is released, and spring-controlled levers on the front jaw are arranged to throw the heads of the flax over. A fork-like device 50 is arranged on the machine to loosen the soil around the roots of the flax.
Patent GB-687500-A (GB)
Title: An antibiotic and the preparation thereof
Filed: 1950-05-15
Abstract: An antibiotic "Viomycin" (Registered Trade Mark), is prepared from the fermentation broth obtained by cultivating a Viomycin-producing strain of Streptomyces puniceus, or a mutant thereof, in an aqueous nutrient medium containing carbohydrate, preferably adjusted to pH7, with submerged aerobic conditions, a temperature of 24 DEG  to 30 DEG C. and 2 to 7 days fermentation.  The culture medium contains carbohydrate, e.g. sugars, starch and glycerol; organic nitrogen, e.g. soybean meal and wheat gluten; growth substances, e.g. distillers' solubles; sodium chloride and buffering agents, e.g. calcium carbonate.  The antibiotic may be isolated by (a) precipitation with acid fast dyes or (b) adsorption on a cationexchange resin.  For (a) the preferred dye is Eriochrome Violet, others which may be used are: Erio Fast Cyanine, Pontamine Fast Orange, Alizarin Red S, Synthracine Blue, Pontamine Steel Blue, Polar Yellow, Methyl Orange and Pontamine Green.  The dye salt formed may be treated, e.g. triethylamine sulphate in the presence of a solvent, e.g. methanol or methanol-acetone and the Viomycin sulphate filtered off. Alternatively a solution of the dye salt may be treated with an inorganic salt, e.g. Bacl or bacl2, and the precipitated metal dye salt removed.  The antibiotic may be obtained from the resin eluate by freeze drying, or by the addition of solvents such as methanol and butanol.  Two antibiotics are present in the fermentation broth; the major component Viomycin is isolated by the above methods.  The preparation of the reineckate, picrate, b -naphthelene sulphonate, sulphate and hydrochloride of Viomycin is described.  Viomycin is a basic antibiotic containing C,H,O and N and forming salts with organic and inorganic acids.  The sulphate and hydrochloride (mpt. 265-8 DEG  C.) are soluble in water, sparingly soluble in methanol, acetone and b -methoxyethanol. Viomycin sulphate [a ]25D = -31.3 DEG  (H2O 1 per cent), E1 per cent1 cm. at 267.5 mm = 285.  The micro organism S. puniceus is described.
