Title: Improvements in or relating to arylmethylamine derivatives
IPC: C07D307/91
Filed: 1950-08-09
Abstract: The invention comprises compounds of the formula <FORM:0703257/IV(b)/1> where NX is morpholino, piperidino, dialkylamino, di-(hydroxyalkyl)-amino or alkyl-(hydroxyalkyl)-amino, and their hydrohalide salts.

Filed: 1945-08-02
Abstract: 596,744. Pruning shears. TUCKER, G. E. Aug. 2, 1945, No. 19846. [Class 30] In pruning shears or secateurs of the type in which one jaw has a fixed cutting edge and the other has mounted on it a rotary cutter which is interconnected with the first jaw so that closing of the jaws causes rotation of the rotary cutter to effect shearing action, the jaw carrying the rotary cutter is recessed to receive the cutter and thereby protects and shrouds that part of the cutter which at the time is not in use. A rotary cutter 6, with bevelled cutting edge 8, is mounted on a pivot bolt 9 in the recess 10 of the jaw 1, and the jaw 2, with fixed cutting edge 7, has a pin 12 which engages with a slot 11 in the cutter 6 to give partial rotation of the cutter when the jaws are brought together. A number of slots 13 may bo provided so that different parts of the rotary cutter may be utilised. To reduce the size of the head of the shears, the cutter 6 may be formed as a segmented member only and the jaw 1 correspondingly reduced. According to the Provisional Specification, the jaws may be mounted one at the end of a long pole and the other connected with and operated by a lever at the other end of the pole.
Patent GB-589245-A (GB)
Title: Method of dyeing cellulose acetate and compositions for use therein
IPC: D06P1/651
Filed: 1944-10-16
Abstract: Cellulose acetate, e.g. in the form of yarns, woven fabrics, piece goods, films or sheets, is dyed by treatment with a composition containing an aqueous solution of an acid, basic or indigosol dye, free inorganic and/or organic acid or acids, and an organic solvent having an aliphatic hydrocarbon nucleus and containing at least two atoms of oxygen doubly or singly linked to carbon in an ester, ether, alcohol or ketone structure.  The pH value of the solution is preferably 2.23 or below.  The organic solvent, or the organic acid if used, may be an active solvent of cellulose acetate, in which case the concentration thereof is preferably between on the one hand the "threshold concentration" (at which the solution first exhibits wetting ability and penetration into the cellulose acetate greater than that of water) and on the other hand either the "delustring concentration" (at which delustring of the cellulose acetate beings to occur) or the "critical swelling concentration" (at which the solution begins to be absorbed by and to swell the cellulose acetate).  The best results are obtained by using an organic solvent and an organic acid which are both active solvents of cellulose acetate, with the further addition of an inorganic p  acid.  The process is particularly applicable to the dyeing of cellulose acetate threads, e.g. pencil stripes in men's suitings, prior to dyeing of other materials associated therewith, e.g. union dyeing of cotton or acid, acid-chrome or neutral cross-dyeing of wool (to which dyeings the cellulose acetate is resistant).  Tables show the results obtained with various combinations and concentrations of the following materials: acids: formic, acetic, propionic, lactic, oxalic, monochloracetic and sulphuric; solvents: ethylene glycol mono- and di-ethyl, monobutyl and monobenzyl ethers, the methyl and ethyl ethers of ethylene glycol monoacetate, acetonylacetone, dioxane, diethylene glycol monoethyl ether and its acetate, tetraethylene glycol dimethyl ether, diacetone alcohol, ethyl acetate and glycol diformate; dyes: Azo Rubinol 3GP, Wool Fast Blue GL, Alizarine Cyanine Green GHA or GLS, Xylene Milling Blue 6G, Sulfonine Brown 2R and National Milling Yellow 3GG.  In examples: (1) Bright Celanese yarn (the word "Celanese" is a Registered Trade Mark) is dyed at about 115 DEG  F. from an aqueous solution of Alizarine Cyanine Green GHA concentrated containing ethylene glycol monoethyl ether and formic acid; (2) a fabric of Faille Taffeta consisting of Bright Acele in the warp and Dull Acele in the filling is dyed in a similar bath, but using as the dyestuff a mixture of Azo Rubinol 3GP, Xylene Fast Yellow ES and Alizarine Light Violet RS.  Specification 559,991 is referred to.  The Specification as open to inspection under Sect. 91 comprises also the use of aliphatic solvents containing a single oxygen atom combined with carbon in an ether, alcohol or ketone structure, e.g. ethylene chlorhydrin.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1385745 Colour television tubes RCA CORPORATION 1 May 1972 [14 Jan 1972] 20047/72 Heading H1D A colour television tube of the shadow mask type using three co-planar beams, is provided with a deflection yoke adapted to produce a pin cushion shaped horizontal deflecting field which causes under convergence at extreme horizontal deflection, and a barrel-shaped vertical deflecting field which causes over-convergence at extreme vertical deflection; and the electron gun is adapted to produce a spacing between the beams at the centre of the deflection yoke not greater than 0À2 inch. Dynamic convergence arrangements are then unnecessary but may be provided for larger tubes. The electron gun may comprise three individual cathodes and common G1 to G4 electrodes provided with apertures for the beams; the outer apertures of the final electrode may be surrounded by magnetically permeable material such as nickel iron to partly screen the outer beams from the deflection fields and thereby equalize the raster sizes for the three colours. The deflection yoke is as described in Specification 1385747 and is preferaby toroidal but saddle coils may be used. The shadow mask may be provided with elongate apertures, and the fluorescent screen may comprise stripes of different colours.

[Class 64 (i)] [See also Group XXIX] In a digester of the Sinclair type having a perforated inner bottom 4, an upper valve casing 7 in the form of a dome or a cone or with conical projections above this bottom has discharge openings 8 for digested pulp, and a lower cylindrical valve casing 9 between the inner bottom and a discharge opening 16 for pulp in the bottom of the digester has openings 10 for liquor circulation ; a rotatable valve 12 with a cylindrical extension 14 apertured at 13, 15 in the valve casings opens one set of openings and closes the other. The conical parts of the upper casing and valve have small holes 43 allowing circulation of water when the lower valve is open and the upper valve is closed for pulp. The inner parts 12, 14 of the valves are first lowered and then rotated by a central shaft 24, a stop 40 limiting the motion. The shaft 24 has a collar 31, is threaded at 29 and has a lower washer 35 limiting the distance of lowering of the valve before rotation, which is prevented during lowering by a stop 40 engaging a vertical groove 41 in the valve. The liquid is circulated through external tubes by a force pump or through internal vomit pipes 18 under which air steam or water is injected. Valves 19 may close the tops of vomit pipes so that pulp to be discharged may be stirred by the jets or floated off the inner bottom 4 when the lower openings 10 are closed. The inner bottom 4 may be constructed with ridges according to Specification 458,863.

The grab arms 1, 2 of a sack-lifting grab are movably mounted relative to a bar 11, and means are provided so that on lifting of the bar the arms 1, 2 are prevented from separating. The bar 11 comprises two spaced bars connected at their ends and preferably also intermediately, between which the arms 1, 2 pass. The mounting may be by a bar 19, Fig. 1, so shaped as to urge pins 20, 21 on the arms 1, 2 together on lifting, or may comprise links 29, 30, Fig. 7, separation of the arms being prevented in this case by a pin 32 attached to the arm 2 and engaging a notch 31 in the link 30. In either case the arms are urged together by a spring and are separated after lowering by links 9 which may be pulled over-centre by a rod 10. A circular jaw 5 mounted on the arm 2 cooperates with a semi-circular recessed jaw 3 on the arm 1 to grip a sack. The grab is intended for mounting by trunnions 17, 18 on a tractor fore-loader, and operation of the rod 10 may be by mechanical, electric or hydraulic means.
