Patent GB-304436-A (GB)
Title: Process for the manufacture and production of salts of acid sulphuric esters of nitro-9.10-dihydroxyanthracenes
Filed: 1927-12-09
Abstract: 304,436. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Dec. 9, 1927. Sulphuric acid ester-salts of nitroanthraquinols are obtained by treating a nitroanthraquinone with a metal in presence of a tertiary base and sulphur trioxide, halogensulphonic acids, or alkyl sulphuric halides. In examples, a- and #-nitroanthraquinones, 1-nitro-2-methylanthraquinone, and 1 : 5-dinitroanthraquinone are treated with methyl sulphuric acid chloride or chlorsulphonic acid in the presence of copper powder and pyridine. When treated with acid oxidizing agents, the esters regenerate the nitroanthraquinones, while non-oxidizing acids cause a reaction with formation of a mixture of nitro and aminoanthraquinone. An aqueous solution of the pyridimum ester salt from 1-nitro-2-methylanthraquinone deposits an insoluble red crystalline substance on standing. Specifications 247,787, 251,491, and 261,139 are referred to.

Abstract: 442,460. Crank-linkages. FELIES, J. F., 56, St. Jansplein, Antwerp, Belgium. Nov. 20, 1934, No. 33406. Convention date, Nov. 21, 1933. [Class 80 (iii)] [See also Group XXVII] Crank pin-and-slot mechanism, particularly applicable as the driving-gear of internal-combustion engines, has a guide body 3 so constructed that two crank-pin blocks 4, 5 cooperating with this body are moved at an oblique angle with regard to each other. The piston 2 reciprocates in the cylinder 1 and, at its lower end, is secured to the body 3 by a cotter 11 extending through an extension 10 of the body. If one of the rubbing surfaces 3<a>, 3<b>, wears more than the other, the piston and body descend slightly and move laterally to maintain contact with both crank-pin blocks and correct alignment of the piston. In a modification, the piston is so secured to the guide body that relative motion between the two in a plane transverse to the piston axis is possible ; hence, when the lateral movement of the piston is arrested, the body may continue its movement. The Specification as open to inspection under Sect. 91, refers to the piston being in two parts movable laterally relatively to one another. This subject-matter does not appear in the Specification as accepted.

Abstract: 421,805. Variable-stroke mechanism. DAWBARN, F. H., 10, Farquhar Road, Edgbaston, Birmingham. March 27, 1933, No. 33978 /32. [Class 80 (iii)] [See also Group XXVIII] In a variable-gear mechanism of the kind wherein motion is transmitted from a driving member to a driven member through a pivoted lever the mechanical advantage of the transmission is varied automatically according to the load by arranging the lever in an inclined position relative to the line of force of the load and guiding it so that it can move transversely under the influence of the load against a controlling resistance. Figs. 2 and 6, show an application of the mechanism to a variable stroke pump, the levers 16 being pivotally mounted at 18 upon a floating ring 19 the rotation of which is controlled by a spring 42. The levers 16 are driven by a cam 13 and are of channel section in which rollers 20, to which radially acting plungers are attached, engage. Thus according to the load on the radial plungers, and due to the inclination of the levers 16 to the plungers, the pivots 18 on the floating ring 19 are moved towards the rollers 20 against the resistance of the spring 42 to vary the stroke of the pump and the mechanical advantage of the transmission.
Patent GB-392465-A (GB)
Title: Manufacture of porous materials
IPC: C04B38/06
Filed: 1932-12-01
Abstract: In a process in which a volatile solid, such as naphthalene or paradichlorobenzene is used as pore-forming material in making porous bricks &c., kieselguhr is added to the clay to absorb oily impurities in the naphthalene &c. so that by condensing the vapours a pure grade of naphthalene &c. is obtained.  In an example, a composition comprising clay, kieselguhr, sawdust and naphthalene is made plastic with water, moulded, and placed in a current of hot air preferably below the melting-point of naphthalene.  The vapours are collected and condensed to form flakes of a pure grade.ALSO:Porous bricks, blocks, slabs, &c. are made by shaping a plastic earthy material, e.g. clay, containing a solid combustible non-volatile ingredient and a removable ingredient as poreforming agents, removing the volatile ingredient and water from the shaped mass and firing.  During the firing the combustible ingredient is burnt out.  The combustible ingredient may be sawdust, wood meal, fibres, &c.  The removable ingredient may be volatile substances which volatilize from the solid at temperatures which permit of volatilizing water from the mass, e.g. naphthalene or paradichlorobenzene, or less volatile ingredients, e.g. sulphur which can be volatilized from the dried brick.  The removable ingredients may also be extracted by solvents. In an example, a composition comprises 43,5 parts of clay, 4,5 parts of kieselguhr, 16 parts of sawdust, 36 parts of naphthalene and sufficient water to make a plastic mass.  The mass is moulded and placed in a current of hot air, preferably below the meltingpoint of naphthalene, to remove the water and naphthalene.  The porous mass is then fired in the usual way.  The kieselguhr acts to absorb the oily impurities of the naphthalene, and the naphthalene vapours which are given off may be collected and condensed to form flakes of a pure grade.  Other volatile poreforming material may be recovered in a like manner.
