Title: Improvements in or relating to dyestuffs
IPC: C09B23/01
Filed: 1940-04-19
Abstract: 540,578. Photographic sensitizing dyes ; dyeing cellulose esters. KENDALL, J. D., and FRY, D. J. April 19, 1940, No. 7078. [Classes 2 (iii) and 15 (ii)] [Also in Group XX] Dyestuffs which may be used for sensitizing photographic silver halide emulsions or for dyeing textiles, particularly cellulose acetate artificial silk, are made by condensing a compound of the general formula where R, is a hydrocarbon group and R 2  is a hydrogen atom or hydrocarbon group, with an alkyl or aralkyl ester and condensing the product with a quaternary salt of a heterocyclic nitrogen compound containing a reactive methyl group in the x- or y position to the heterocyclic nitrogen atom. The alkyl ester used is preferably an alkyl-p-toluene sulphonate, and the process may be carried out by mixing the compound of the general formula with the heterocyclic nitrogen compound and with sufficient alkyl-p-toluene sulphonate to convert both compounds to quaternary salts, the condensation being effected by heating the fused mixture with an acid-binding agent, e.g. pyridine. The products, when obtained as p-toluene sulphonates, may be converted into salts of inorganic acids by treating them with a solution of a salt of the desired acid, e.g. an alkali metal halide. The parent materials of the general formula may be made by the process of Specification 540,577. Heterocyclic nitrogen compounds which may be used include thiazoles, oxazoles, and selenazoles, pyridines, quinolines, naphthaquinolines, indolenines, diazines, diazoles, oxazolines, thiazolines and selenazolines. In examples, compounds of the general formula in which R 1  is methyl or ethyl, and R  2  is methyl are condensed with methyl or ethyl-p-toluene sulphonate and 1-methylbenzthiazole, quinaldine or 1-methylbenzoxazole. In the use of the products for dyeing cellulose acetate fabrics, the dyebaths may be simple aqueous solutions, where the dyestuffs are sufficiently soluble, or the dyestuffs may be dispersed with the acid of the usual dispersing agents, e.g. Turkey red oil, sulphoricinoleic acid, naphthenic and sulphonated naphthenic acids, sulphonated naphthalene-formaldehyde condensation products, and sulphonated long chain fatty alcohols. Examples of the dyeing process are given. The Provisional Specification describes also the use as parent materials of compounds of the general formula in which R 1  is hydrogen, and in which the ring sulphur atom is replaced by oxygen. It also comprises the condensation of the parent materials with any of the seven types of compounds described in Specification 489,335. The products containing thione groupings may be treated with alkyl or aralkyl salts and further condensed with compounds of these seven types. Specifications 426,718 and 438,420 also are referred to.

Abstract: 987,982. Drafting fibres. JAMES MACKIE & SONS Ltd. Feb. 12, 1962 [Feb. 28, 1961], No. 7313/61. Headings D1D and D1N. In a textile drafting mechanism for the treatment of a number of parallel slivers which are combined, after drafting, to form a single sliver and in which the draft is automatically regulated in accordance with the average thickness of the slivers entering the drafting zone, members are provided between the drafting delivery rollers 7 and 8 and the doubling plate 9 to provide paths of individually adjustable length so that each sliver travels approximately the same distance between the drafting delivery rollers 7, 8 and the delivery rollers 16. As shown, these individual paths are formed by rods 20, 22, 23 and a common driven roller 21. The rods 20, 22, 23 are mounted on adjustable supports 27, 28, 29 so that the differences in path lengths introduced by the slivers passing through the doubling plate 9 can be cancelled. Curved plates 25, 26 are provided to facilitate threading up. When, as shown, the invention is applied to a Gill box (working jute or like fibres) the path lengths of the different slivers are adjusted to differ slightly so that the irregularities introduced simultaneously in each separate sliver by the removal of the faller pins therefrom, do not coincide to form combined irregularities in the combined sliver.

Filed: 1924-03-26
Abstract: 227,406. Chateau, E. H. F. Jan. 7, 1924, [Convention date]. Crystal detectors.-The crystal 12 is held in a recess in a block of insulating material 1 by a disc 9 of insulating material in a metal casing 7 secured by a bayoneti joint to the block 1. The contact wire 16 is carried by a member 17 resting on a spring 15. The controlling spindle 11 carries a cam 13 which is so shaped that when the handle 12 is turned a member 10 slidable in the casing is gradually depressed against a spring 8 to force the wire 16 into contact witla the crystal, and is then suddenly released. Owing to the fact that in the normal position of the member 10 there is some clearance between it and the member 17, the latter is free to move laterally and will usually do so when suddenly released. When a sensitive point is found, the best pressure is obtained by adjusting the handle 12.

Abstract: 426,372. Ice-cream servers. CHESTER, F. R., 1421, Burnaby Street, Vancouver, Canada. March 10, 1934, No. 7688. [Class 87 (ii)] A scoop for ice-cream &c. has a receptacle provided with an aperture through which icecream extrudes during the filling operation to prevent undue compression of the material in the scoop. The semi-spherical receptacle 1 is carried by a handle 4 and the aperture 2 is positioned eccentrically in its wall. An operating lever 7 is pivoted on the handle 4 and controlled by a spring in the boss 8. The lever 7 carries an apertured plate 10, forming a V-shaped cam, and an upstanding fork 11. A double cranked shaft 17 is mounted in bearings on the handle 4 and carries a semicircular knife 23 having a pivot pin 24 at its free end. The bearing 14 has a gap 16 which engages an enlargement 20 on the shaft so that the shaft may be sprung out of the bearing and the knife thus removed. In operation, the scoop is first filled and the lever 7 is operated so that one arm Y of the cam slot 10 engages the crank 18 and thus rotates the knife 23 to sever the material extruded through the aperture 2. The fork 11 also engages the crank 19 to carry it over dead centre. The knife 23 is arrested by a ball 6 which runs in a groove 5 in the handle 4 and is engaged in a recess 12 in the lever 7. When the scoop is inverted the ball 6 drops into the recess 12, thus allowing the lever 7 to rotate the knife through the second half of its movement to detach the ice-cream from the scoop.

Abstract: 692,986. Gyroscopes. BENDIX AVIATION CORPORATION. March 26, 1952 [March 28, 1951], No. 7787/52. Class 97 (iii). [Also in Group XXXVII] In a three degree of freedom gyroscope there is provided a brake for restraining movement of the gyroscope rotor about one axis, a solenoid arranged to operate the brake, and a time delay device controlling the solenoid to release the brake a predetermined time after power has been applied to rotate the rotor. As shown, the rotor casing 3 is jourrialled about axis X-X in gimbal 5 which is rotatable about axis Y-Y in frame 7. A rotor winding 11 and stator winding 15 provide altitude signals about axis X-X, a similar arrangement providing altitude signals about axis Y-Y. Fixed to trunnion 21 is a brake drum 23 engaged by a brake shoe 27 when the rotor speed is too low to prevent nutation, this shoe being pivoted at 31, spring urged at 33 into engagement with the drum and retractable by a solenoid 35. This solenoid is energized by battery 39 and is connected in series with a switch 41 and a bi-metallic time delay device 47. Switch 41 is mechanically connected with a switch 45 for connecting the gyro motor 43 across a 3-phase source. Switch 41 closes on closure of switch 45 and a heater coil 51 in device 47 causes a bi-metallic element 49, after the time necessary for rotor 1 to attain its operating speed, to flex sufficiently to close contacts 53, 55, whereby solenoid 35 is energized and the brake released. When switch 45 is opened, the solenoid is automatically deenergized and brake 27 is applied.

Abstract: 1464912 Keyboards with coded outputs CASIO COMPUTER CO Ltd 20 Feb 1974 [26 Feb 1973(2)] 7812/74 Heading G4H The invention relates to a keyboard wherein keys 16 connect selected rows and columns of a matrix 15. As shown in Fig. 2, a clock 12 drives a counter 11 the outputs 11a, 11b from which are fed to decoders 13, 18. The sequential outputs 14a- 14h from decoder 13 address the rows of matrix 15 from one column of which is produced a signal which is fed to one of gates 17. Gates 17 are sequentially enabled by the outputs 19a- 19h from decoder 18; one of the gates will thus be enabled by the matrix and the decoder, and a signal is sent to a gate 20 at a time which represents the depressed key. The output from gate 20 thus enables gates 21 to pass the output from counter 11 which corresponds to the chosen key 16. Instead of counter 11 and decoders 13, 18 ring counters 22, 23, Fig. 3 (not shown), may be used. Counter (22) addresses the matrix rows, counter (23) selects gates 17, and both counters drive an encoder (24) connected to gates 21. Encoder (24) may be omitted, when the clock pulses which drive the ring counters are used to drive a counter 26, Fig. 4 (not shown), connected to gates 21. The apparatus may be modified (Figs. 5, 6 not shown), to eliminate the effects of contact bounce, to ensure that one output is produced for each depressed key and to provide sequential outputs for substantially simultaneously depressed keys.
