Title: Improvements in the preparation of hydrophilic aminotriazine-aldehyde resins
IPC: D06M15/423
Filed: 1948-02-23
Abstract: Water soluble aminotriazine-aldehyde resins are produced by reacting a hydrophobic aminotriazine-aldehyde condensation product with an alkali metal sulphite under alkaline conditions.  Sodium sulphite may be used but the bisulphite, hydrosulphite or metabisulphite is preferred.  The products may be syrupy or may be dried to powder form.  They may be used as aqueous dispersions, e.g. for improving the wet strength of paper (see Group VIII), the crease-resistance of cellulosic fabrics (see Group IV (c)), for bleaching leather (see Group VIII), or for adhesives if desired with customary fillers and hardeners.  In examples: (1) a hydrophobic product from 1 mol. melamine and 3 mols. formaldehyde at pH 8.5 was refluxed with 0.3 mols. of sodium bisulphite and water.  Product is a clear gel which may be dispersed in water; (2) the product of example (1) was spray dried.  Examples (3) and (4) are similar to (1) but use sodium metabisulphite, and example (6) describes a plywood adhesive paste consisting of the resin powder of example 2, water, wood flour and oxalic acid. Specifications 595,366 and 611,244 are referred to.ALSO:Water-soluble amino-triazine-aldehyde resins (see Group IV (a)), are used for the treatment of cellulosic fabrics.  In example 7 cotton cloth was impregnated with an aqueous solution containing triethanolamine phosphate and a melamine-formaldehyde condensation product which has been rendered water-soluble by treatment with an alkali metal sulphite under alkaline conditions, and was dried.  It had improved shrink and crease resistance.

Title: Improvements in or relating to stabilized organic sulfur-containing copounds
IPC: C10M135/02
Filed: 1953-02-27
Abstract: Liquid organic sulphur-containing materials which normally evolve hydrogen sulphide are stabilized by contacting them with an oxide of nitrogen under conditions such that there is no substantial loss of total sulphur content.  The treatment is carried out in the absence of water and preferably at about 50-250 DEG  F.  The oxide of nitrogen may be passed at about 0.1 to 100 cu. ft. per hour per gallon of sulphur-containing compound for about 5 minutes to 10 hours.  In examples: (1) the product resulting from treating barium tert.-octylphenol sulphide with phosphorus pentasulphide is treated with a mixture of NO and NO2; (2) sulphurized dipentene is similarly treated.  Other materials which may be treated are sulphurized and phosphosulphurized olefines, olefine polymers, diolefines, acetylenes, aromatics, and petroleum fractions, and sulphurized organic acids and esters, higher alcohols, ketones and aldehydes, phenols and amines.ALSO:Mineral oil compositions comprise a mineral oil (e.g. a lubricant base stock, heating oil or gasoline) and a liquid sulphur-containing material which normally evolves hydrogen sulphide but which, to prevent such evolution, has been treated (if desired in the presence of the oil) with an oxide of nitrogen under conditions such that there is no substantial change in total sulphur content, and in the substantial absence of water. Advantageously the sulphur compound is present in an amount of about 0.01 to 10 per cent by weight, whilst lubricant compositions may also contain other known additives, e.g. viscosity index improvers and detergents.  In an example, a lubricating oil blend contains 2.5 per cent of sulphurized dipentene which has been treated with a mixture of NO and NO2.

Title: Improvements relating to flyers for textile twisting spindles
IPC: B65H57/20
Filed: 1963-02-12
Abstract: In a textile apparatus, e.g. a double twist spindle, a flyer is in friction contact with a braking or bearing surface concentric to its axis and is movable along said axis in such a way that the braking of the flyer is reduced by increasing thread tension.  The flyer is pivotable about an axis transverse to its axis of rotation in dependence on thread tension and is provided with bearing element successively supporting the flyer in its pivoting so as to vary the friction between the flyer and the bearing or braking surface.  In Figs 1 and 3 (not shown) the flyer comprises a sleeve 6 on which flyer arms 9 are pivotally mounted transversely of the spindle axis by means of pins 7,8, the sleeve 6 being supported on a stationary braking surface 3 and adjustably pressed there against by weights 16. Rollers 11 are mounted on stub shafts 15 which are mounted by plates 13,14 on the flyer arms and pass through apertures 12 in the sleeve 6.  At rest the rollers 11 are clear of the upper surface 5 of the package support 2.  During operation the flyer arm 9 is tilted by the tension in the thread 18; if this tension rises above a certain value a roller 11 is forced into contact with the surface 5 and the sleeve 6 is lifted away from the braking surface 5, the flyer then being supported by the roller 11 running on a surface 10.  The drag on the flyer is thus reduced and the thread tension lowered; the thread tension is thus regulated.  In Fig. 6 (not shown) a roller 21 is located outside the flyer sleeve while the inner end 20 of the stub shaft ends in a point.  This device operates in two stages: as the thread tension initially increases the point 20 is brough into contact with the surface 5 to lift the sleeve; then, when the tension rises above a second level the roller 21 comes in contact with a flange outside the sleeve and the point 20 is lifted clear of the surface 5 so giving a two step reduction in flyer drag.

Abstract: 812,799. Pulse radar; aerials. DECCA RECORD CO. Ltd. May 23, 1957 [Feb. 23, 1956], No. 5718/56. Class 40 (7). [Also in Group XL (b)] Radar apparatus includes a waveguide system for providing rectangular section horn aerial with waves of adjustable ellipticity or direction of linear polarization. The embodiment described (see Fig. 1) comprises a pulse radar transmitter 10 feeding through a duplexer 11 waves linearly polarized with the electric vector parallel to the shorter side of rectangular waveguide 12, to a rotating coupling 21 formed by relatively rotatable circular coaxial lines 23, 24. Rectangular waveguide 26 is coupled by transition section 27 to square waveguide 28 which is coupled by further transition section 29 to square waveguide 30 whose walls are at 45 degrees to those of guide 28. Guide 30 (see Fig. 5) incorporates a phase shifter comprising a dielectric sheet 31 adjustable by rods 32 which may be remotely controlled by a power-driven cam. The output wave from the phase-shifting section is in general an elliptically-polarized wave; when it degenerates into a linearlypolarized wave the plane of polarization can be rotated by rotating the assembly lying between couplings 21, 42. The major axis of the ellipse may be rotated likewise. Conversely, received elliptically-polarized signals are converted into linearly-polarized waves at duplexer 11. Waveguide 28 has an internal wire grating 50 (see also Fig. 4), a rectangular slot 51 and a dummy load 53, so that waves of undesired polarization may be absorbed; the load may be replaced by a receiver. The invention may be used to minimize interference from rain or from other transmitters. The horn aerial may illuminate a reflector 14 or a lens, forming part of an aerial system for rotational or oscillatory scanning. Specification 805,977 is referred to.
