IPC: F23H11/00
Filed: 1924-06-13
Abstract: 219.948. Wood. W. R. Aug. 3. 1923. [Convention date]. Grates. - In a travelling grate the links of which may be of the form described in Specification 202,692, the upper run of the grate, which follows a curved path, as shown in Fig. 1, is supported in such a way that the links are pressed together transversely but without causing lateral displacement of the grate as a whole. In the arrangement described, the supporting surface is composed of rollers 12 the axes of which, as shown in Fig. 2, are slightly on the skew, adjacent rollers being inclined in opposite directions and provided with flanges 17 at opposite ends.

Title: Improvements in or relating to the compression of gaseous fluids
Filed: 1934-05-12
Abstract: 438,134. Air compressors. STITT, R. R., 1929, Glendale Avenue, Detroit, Michigan, U.S.A. May 12, 1934, No. 14402. [Class 8 (i)] [See also Group XXVI] Air is admitted alternately to the opposite ends of a vacuum cylinder 2, Fig. 3, operating a power piston 5 and compressor pistons 7, 8 on the same piston rod. The air deposits moisture in the vacuum cylinder, and on the instroke of the piston a part of the air enters the corresponding compressor cylinder, the piston of which comprises perforated end plates between which an intermediate piece moves with lost motion, forming a valve. The vacuum distributing valve 14 communicates interiorly with a vacuum conduit 13 opening, e.g. to the manifold of a vehicle engine, into which the condensed moisture and oil are drawn, while the casing 12 of the valve opens, e.g., to the engine crank case, the oil vapours carried over lubricating the valve and pistons. The valve is actuated through a cage 14 oscillated by a pivoted arm 16, Fig. 1, connected by a spring 20 with a shifter rod 21 which carries arms (not shown) operated by striking the piston 5. The compressors supply storage tanks on the vehicle, a valve allowing these tanks to be filled by external means in case of compressor failure.

Title: New colouring matters of the polycyclic ketone, aza, perylene and dioxazine series
IPC: C09B69/00
Filed: 1949-05-30
Abstract: The invention comprises colouring matters of the polycyclic ketone, azo, perylene, and dioxazine series having hydroxybenzyl groups nuclearly attached.  They are obtained by heating with an excess of a phenolic substance, a colouring matter of one of the above series which contains one or more nuclearly attached chlormethyl groups. The phenol may be substituted or contain condensed rings.  The reactants are preferably heated together in presence of a metallic halide such as zinc or aluminium chloride, ferric, stannous, or mercuric chloride.  The halide may be formed in situ, e.g. from zinc oxide or acetate and the hydrogen chloride liberated in the reaction. The products colour textiles, paper, and lacquers, the alkali-soluble or sulphonated products may be coupled with diazotized amines in substance or on the fibre, and those products obtained by the use of salicylic acid may be used as chromable dyestuffs.  Phenolic substances specified are: phenol, hydroquinone, the cresols, 1,3,5 - xylenol, a  - naphthol, p-hydroxydiphenyl, salicylic acid, p-methoxyphenol, o, or p-chlorphenol, and methyl salicylate.  In examples, the following are heated with phenol, in some cases in presence of zinc chloride: (1) bis-chlormethyl-1,4-di-(21 - bromo - 41,61 - dimethylanilino) - anthraquinone; (2) bis-chlormethyl-1,4-di-(p-toluidino)-anthraquinone; (3) bis-chlormethyl-acedianthrone; (4) 4,8-di-(m-chloromethyl-benzoylamino)-anthrarufin; (5) bis-chlormethyl-dibenzanthrone; (6) bis-chlormethyl-4,41-di-(6-methylbenzthiazyl-2)-azobenzene; (7) bis-chlormethyl - perylene - 3,4,9,10 - tetracarboxydiphenylimide (or o-tolylimide or p-chlorphenylimide; (8) bis-chlormethyl-6,13-dichloro-3,4,10,11-dibenztriphendioxazine; (9) bis-chlormethyl - 4,41 - di - (4,6 - dimethylbenzthiazyl-2-)-2,21-dimethyl-azobenzene.  The above chlormethyl bodies may be obtained by reacting the colouring matter with dichlorodimethyl ether in presence of sulphuric acid or in presence of aluminium chloride and a tertiary base.  Specification 576,270 is referred to.

Abstract: 828,075. Knitting-machines. FAHRRADWERK ELITE-DIAMANT VEB. May 10, 1956, No. 14584/56. Addition to 745,525, [Group XXXV] Class 74 (2). Each cam carriage of the machine described in the parent Specification carries a pattern cylinder 470 in which are mounted selectors 50 which are pivoted into operative position by jacquard mechanism 42, 45, so as to effect needle selection of one bed of each pair as the carriage moves along the beds. The jacquard mechanism which operates prior to the passage of each carriage is mounted at the beginning of one pair of needle beds. The pattern cylinder rotates as it passes the jacquard mechanism and continues to rotate to effect needle selection by its selectors after the selectors have been rendered operative. A ring 52 is raised by a cam after the jacquard mechanism has made its selection and before the selectors commence their selection of the needles so as to hold the selectors in their operative or inoperative positions. The members 45 are lowered by a cam on each carriage as the carriages move round so as to be ready for the next selection. The selectors are held in this selected position until the negative carriage has traversed each pair of needle beds whereupon the ring 52 is lowered and a cam engages the selectors 50 and returns them to their inoperative position ready for the next selection by the jacquard mechanism.
