Abstract: 508,717. Printing textiles ;resinous condensation products. SOC. NOBEL FRANCAISE.- Jan. 25, 1938, No. 2329. Convention date, Feb. 2, .1937. [Classes 2 (iii) and 15 (ii)] [Also in Group XVI] Fabrics are printed with preparations containing in admixture (a) one or more phenolformaldehyde resins which are soluble in drying oils, (b) one or more drying oils, (c) an organic solvent. A diluent, e.g. xylene, and a dryer, e.g. a linoleate of cobalt, manganese, lead or calcium, may be .added.. Specified resins are those from formaldehyde and unsubstituted phenols, cresols - or xylenols in which case an addition of a natural resin, such as colophony or ester gum is necessary, and those from formaldehyde and substituted phenols, such as butyl-, amyl- or di-isobutylphenols. Specified . drying oils are linseed and China wood oils and mixtures thereof and these may undergo preliminary treatment by cooking or partial oxidation; a small amount of a non-drying oil, such as castor oil may be incorporated. Specified solvents are glycols and their acetates, glycol ethers and their acetates, alkyl lactates and monochlorhydrins from glycols. In an example, a phenol-for. maldehyde resin is first prepared by mixing together' xylenol, ester gum, trioxymethylene and caustic soda solution, boiling the mixture for 15 minutes,\adding hydrochloric acid solution, boiling for 1, hour, washing with water until neutral; adding more ester gum, cooking the mixture for 2 hours at 210 to 220‹ C. and allowing to cool, and this resin is mixed with China wood oil, the mixture is heated to 270‹ C., so maintained for 10 minutes in a stream of carbon dioxide to prevent yellowing, allowed to cool and, on reaching 90‹ C., adding ethylene glycol monoethyl ether and its acetate. Dyes or pigments may be added and the preparations may be used to produce resist effects with over-dyeing. Specification 499,876 is referred to.

In a break spinning apparatus which includes a rotating spinning chamber 2 and a fibre inlet tube 51, a vibratory movement is imparted to the length of yarn extending between the mouth 32 of the yarn outlet tube 31 and the fibre combining point E on the fibre ring R to reduce the bearing pressure of the tube mouth 32 on the yarn. The vibratory movement may be obtained by (1) oscillating the outlet tube axially (Fig. 1) or transversely by means of a motor driven arm 33, (2) arranging the tube mouth eccentrically of the chamber (Fig. 11), (3) vibrating. the thread itself e.g. (Fig. 19) by vibrating a deflecting withdrawal roller 300 mounted on an arm 331 which is attracted periodically by an electromagnet 360, or (4) irregularly shaping the outlet tube mouth, e.g. inclining it to the longitudinal axis (Fig. 4), providing a projection or groove at the mouth edge. The vibration frequency can be altered by varying the relative rotational speed of the outlet tube and the spinning chamber. Option (2) can be obtained by mounting the outlet tube in a rotatable insert 113, the inserts of a plurality of similar spinning chambers being collectively displaced by means of a rack engaging-toothed wheels 113 on the inserts.

Abstract: 1,063,258. Transistors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 21, 1964 [Dec. 27, 1963], No. 51751/64. Heading H1K. A transistor is made by diffusing donor (acceptor) material through a mask into one face of a P (N) type semi-conductor body to form an N (P) type collector region enclosing one or more undiffused areas, epitaxially depositing a P (N) layer over said face and then diffusing donor (acceptor) material into the layer to form an emitter region extending over and beyond the enclosed area or areas. A typical transistor (Fig. 12) is formed in this way from a P-type silicon disc. The arsenic diffused collector region 18 is extended to the upper face at 21 by diffusing phosphorus through the periphery of the epitaxial layer 19, and the base contact 22 made to the lower face of the disc. In an alternative device (Fig. 5, -not shown), the collector region is of grating form. Both constructions reduce the surface recombination of minority carriers.

The means for heating the container may be an oxy-acetylene burner 12 held at the bottom of the gun so that its frame warms the bottom of the container. Compressed air passes from a source, through ducts 48, 47 past valve 50 opened by pressure on the trigger 31 pushing a valve stem 52, through duct 45, past a maximum air flow valve 49, and duct 44 to chamber 34. The air may then pass directly out through a duct 35 to port 21; however a portion of the air is passed through port 42, past an adjustable valve 43 and through port 40 to the interior of the container to pressurise the metal. Valve 25 is opened by further pressure on trigger 31 which causes an extension 131 to press a knob 29 and open the valve. Metal then flows from container 4 through duct 24 to port 20, from where it is sprayed owing to the entraining action of the compressed air from port 21 and the pressure of air above the liquid metal in the pot. The container is closed by a cover 56 which is rotatably pivoted to the body of the gun. In an alternative embodiment the jacket 34 is replaced by a coil which is positioned inside the container.
