IPC: D06P1/12
Filed: 1952-12-29
Abstract: Compounds of the formula <FORM:0742260/IV(a)/1> or of the formula <FORM:0742260/IV(a)/2> in which X and Y each represents an alkyl or alkoxy group or a halogen atom, or one of them represents such group or atom and the other represents hydrogen, and R represents a radical of the benzene series may be prepared by reacting phenyl isocyanates with the appropriately substituted amino-nitro-compounds followed by reduction of the products so obtained, or by nitrating and reducing appropriately substituted diphenylureas.  The preparation of 4-methoxy-21,41-dimethyl-51-amino- and 3,6-dimethoxy-4-amino-1,11-diphenylurea is given.ALSO:Azoic dyeings, fast to cross-dyeing, are produced on acetyl cellulose, linear polyamide and polyurethane fibres by applying from a single bath a diazotizable amine of the formula:- <FORM:0742260/IV(c)/1> or of the formula:- <FORM:0742260/IV(c)/2> wherein R is a radical of the benzene series and X and Y each represents an alkyl or alkoxy group or a halogen atom, or one of them represents such group or atom and the other represents hydrogen, and a coupling agent comprising an arylamide of 2 : 3-hydroxynaphthoic acid or of 6-bromo-or 6-methoxy-2:3 hydroxynaphthoic acid, effecting diazotisation on the fibre and developing the dyestuff in a hot bath.  In an example cellulose acetate yarn is treated in an aqueous bath at 75 DEG C. containing N-(5-amino - 2 : 4 - dimethoxyphenyl) - N1 - phenyl - urea, 1 - (21 : 31 - hydroxynaphthoylamino)-2-methoxybenzene, diethanolamine, sodium chloride, caustic soda and the condensation product from oleic acid chloride and a protein decomposition product, preferably lysalbic acid, as described in Specification 413,016, diazotisation is then effected with acidified sodium nitrate solution and development of the dyestuff effected with hot sodium acetate solution.  Long lists of other diazotisable amines and coupling components are given.

Abstract: 682,785. Impact pulverizers. TULLIS, D. R. Dec. 27, 1950 [Dec. 24, 1949], No. 33050/49. Class 59 An impact mill, of the type having knife blades 3 pivoted on a rotor 2 and a screen 4 through which ground material is discharged to an outlet 5, has an aperture 8 in the casing 1 which can be uncovered by an automatically-operating flap 9 to allow tough unground material to be diverted out of the casing. The flap may be a curved plate normally covering the aperture but swingable inwards so that its free end is close to the blades and diverts any accumulation of tough material through the aperture or, as shown, it may be interconnected with a movable deflector 7 of aerofoil section. A butterfly valve in the outlet may be partially or completely closed to set up a back pressure which will assist diversion of the tough material. Automatic timing means may be fitted to operate the flap, back-pressure valve and deflector at predetermined intervalsor photo-electric cell means may be used, sensitive to change of colour of the contents of the mill as, for example, when grinding grass the lightening of colour as unground fibrous material accumulates.

[Class 100 (ii).] Printing-surfaces; blankets. -In means for securing flexible printing-plates or offset-blankets to their cylinders of the kind in which the ends of the plate or blanket are inserted in a narrow longitudinal groove in the cylinder and clamped therein by a bar adapted to be forced edgewise into the groove by devices acting at the ends of the bar, the bar is actuated by collars rotatably mounted on the cylinder shaft and having eccentric grooves engaging pins on the ends of the bar. The collars 12, 14, Figs. 1, 3 and 4, have eccentric grooves 11<x> with slots 11‹ leading to the outside of the collars for the entry of the pins (not shown) extending from the ends of the clamping bars 23, 18. In applying the blanket 10 to the cylinder 8, one end, which is provided with holes, is inserted in the groove of the cylinder and engaged with short pins 16<x>, Fig. 4, projecting from one wall of the groove. The blanket is then wrapped round the cylinder and its other end inserted into the groove. The bar 18, the side of which remote from the pins 16<x> is provided with spike-like projections to engage the blanket, is then inserted so that its end pins engage the grooves 11<x>, and the collars 14 are turned to force the bar fully into the groove. In applying the printing-plate 9 to the cylinder 7, one end is held in the groove by a bar 22 which is pressed against the end of the plate by a spring blade 21 attached to the bar and engaging the opposite wall of the groove. The cylinder is then rotated against the cylinder 8 to wrap the plate about the cylinder and the opposite end of the plate is secured by the bar 23 having sharp projections to engage that end of the plate, and actuated by the collars 12 in a manner similar to that by which the bar 18 was actuated. The spring blade 21 is, by this movement, forced into a recess in the face of the bar 22.

Filed: 1958-10-20
Abstract: 873,361. Projectile fuzes. DIEHL G.m.b.H. Oct. 20, 1958, No. 33490/58. Class 9(1). In a missile fuze a radioactive substance is used to keep safe, to arm, or to fire the explosive charge. Fig. 7 shows one arrangement and Fig. 4 the corresponding circuit. In the safe condition a radioactive S + pellet 36, 47 irradiates a semi-conductor 35, 49 and makes it conducting, forming a short circuit across a primer. To arm the missile the pellet is moved up to a semi-conductor 34, 56 (e.g. Si) in which it produces a charge which is stored in condensers. For firing, the pellet is moved to ionize a spark gap to allow the condensers to discharge through the primer. Other means of firing and keeping safe are possible-e.g. switches, breakable barriers. If the missile misses its target the continuing increase of charge on the condensers can be used to cause self-destruction.

Title: Improved process for electrolytic production of esters

Filed: 1935-12-04
Abstract: 455,463. Electrolytic production of esters. NITROGLYCERIN AKTIEBOLAGET, Gyttorp, Sweden. Dec. 4, 1935, No. 33563. Convention date, Dec. 10, 1934. [Class 41] Esters are produced by anodic oxidation of olefinic hydrocarbons in the presence of an oxyacid or a salt thereof. The method is particularly applicable to the production of nitric acid esters ; a safety explosive containing polyglycol nitrate may be prepared. The anolyte should include a good solvent for the olefine such as acetic acid or acetone and a conducting salt such as calcium nitrate ; the hydroxyl ion concentration is maintained low by addition of nitric and/or acetic acid. Water should be absent if the production of byeproducts such as polyglycol nitrate is to be avoided. The olefine when gaseous may be supplied through a porous anode, preferably under pressure. Alternatively the anolyto may be saturated with the compound outside the cell. The anode material should have a high over-voltage for oxygen ; it may be of smooth platinum, gold or iridium or alloys thereof. Palladium may be employed as anode if side reactions are not to be avoided. The anode compartment may contain a liquid such as chloroform which dissolves the ester as it is formed and is immiscible with the anolyte. Detailed examples are given for the production of nitric acid esters of ethylene, butylene and propylene. Sulphuric acid and phosphoric acid esters may also be prepared by the process.
