Abstract: 593,344. Axle structives; torque rods. RIBBESFORD CO., Ltd., and THORNHILL, P. W. June 15, 1945, No. 15287. [Class 79 (iv) [Also in Group XXXII] In means for controlling movements between a vehicle body and a rigid dead axle comprising a pair of arms extending longitudinally of and each pivotally connected to the body with its other end attached to the dead axle and in which one corresponding pair of arm ends is coupled together by a rigid transverse member, each arm is free to flex or pivot in an outward-upward and inward-downward inclined direction but is constrained against all other movement relative to the transverse member. As shown the rigid transverse member is formed by the dead axle 20 to the enlarged ends 18, 19 of which therear ends of the arms 21, 22 are rigidly anchored. The arms 21, 22 are leaf springs of tempered steel strip, the planes containing which are inclined inwardly and upwardly at 45 degrees, Fig. 3, to intersect at 36 above the centre of gravity 37 of the body 35. The arms 21, 22 which are pivoted at their forward ends to the frame members 13, 14 constrain the body to movement about the point 36 apart from purely vertical up and down movement. In rounding a right hand curve as shown in Fig. 3 the body thus tends to lean to the right instead of to the left. The frame is suspended from the dead axle by helical springs 24, 25. In an alternative construction the arms 21, 22 are universally jointed to downward projections of the dead axle and the rigid transverse member is rigidly secured to the forward ends of the arms 21, 22 adjacent their pivotal connections with the frame. A horizontal torque stay prevents rotation of the dead axle about its points of connection with the arms 21, 22 and the frame is suspended from the dead axle by telescopic spring units. Instead of the arms 21, 22 being flexible they may be rigid, the inclined transverse movement then being obtained by the arms being pivoted to the rigid transverse member about inclined axes, the arms in one such arrangement being of isosceles triangular shape along the base of which is mounted the hinge which may be of the rubber bush type.

Patent GB-704017-A (GB)
Title: Manufacture of dyestuffs of the anthraquinone series
IPC: C09B1/28
Filed: 1951-06-29
Abstract: The invention comprises dyes obtainable by heating the leuco-compound of a water-insoluble anthraquinone dye containing a nuclear cyano group in an aqueous alkaline medium and oxidizing the resulting leuco compound to the quinone form.  Suitable starting materials are the products obtained by the action of aqueous solutions of water-soluble cyanides on 1-amino-4-substituted amino-anthraquinone-2-sulphonic acids where the substituent in the 4-amino group is alkyl, cycloalkyl, aryl, or aralkyl or substituted alkyl &c., e.g. alkoxyalkyl as in Specification 679,589.  The alkali may be sodium carbonate or tetra-potassium pyrophosphate.  The leuco body may be obtained by vatting in the usual way with alkaline hydrosulphite and the further heating may take place in the vat.  A temperature of 40-100 DEG C and a time of 30-120 minutes may be used for heating, and a dispersing agent may be present.  When a lignin sulphonate is used as dispersing agent together with a neutral or alkaline inorganic salt of a monovalent cation which does not form an insoluble soap the solution may be dried without filtration of the dyestuff, to give a dispersible powder.  Other dispersing agents specified are alkyl sulphates, alkyl aryl sulphonates, and polyoxyethylene alcohols or esters.  The products dye cellulose acetate or other cellulose esters of organic acid or cellulose ethers.  In examples (1) 1-amino-2 : 3-dicyano-4-b -methoxyethylamino-anthraquinone is reduced to the leuco body with sodium hydrosulphite and sodium carbonate in aqueous solution and the solution is heated with sodium lauryl sulphate or with lignin sulphonate and tetra-potassium pyrophosphate.  After oxidation with air, the reaction mixture is filtered in the case where lauryl sulphate was used, and simply dried when lignin sulphonate had been used.  Also in examples, (2) 1-amino-2 (3) cyano-4-butylamino-anthraquinone obtained by the action of aqueous potassium cyanide on the 2-sulphonic acid) is treated similarly, using sodium lauryl sulphate.  The sodium hydrosulphite may be omitted if the mixture is ball-milled using iron or steel balls. Specification 639,587 also is referred to.

Abstract: 1,260,187. Vibrating screen separator; sifting apparatus. SWECO Inc. 26 March, 1969 [3 April, 1968], No. 15744/69. Headings B1D and B2H. A screen assembly, for separating liquids and solids or grading dry solids, comprises a stack of flat screens 30, 40, 41, 42 mounted on a common plate 4, which is vibrated by motor 7 with out-of-balance weights 8, 9, at least some screens operating in parallel and having incoming material supplied thereto from pipe 79. In Fig. 1, all screens operate in parallel and material passes on to a pair of dishes 66, 67, with apertures whose effective area is adjusted by rotating one dish upon the other to determine the fraction of material which falls therethrough. This fraction is divided by baffles 57, 56, which project inwards and divert successive fractions of material through apertures 65, 64 on to screens 41, 40. Material which overflows from dishes 66, 67 falls on to screen 42, and material passing baffle 56 falls on to screen 30. The fraction passing through the screens falls on to convex pans and passes to outlets 27, 28. Similar outlets are arranged at right angles to the plane of Fig. 1a to gather material which fails to pass through the screens. Fig. 2a (not shown) illustrates such an arrangement in a two-screen separator. The lower screens are commonly more efficient, since their vibrations are of greater amplitude, so dishes 66, 67 may be adjusted so that screen 42 receives less than one quarter of the incoming material. Figs. 3, 4 (not shown) illustrate alternative means for distributing material to different screens. Fig. 5 (not shown) illustrates a four-screen separator wherein two coarse screens operate in parallel and material passing therethrough is further classified by respective fine screens below, producing three fractions in all.
