Title: Improvements in and relating to the production of colouring matters
IPC: C09B59/00
Filed: 1941-06-20
Abstract: 555,866. Dyes. BRITISH BOOT, SHOE & ALLIED TRADES RESEARCH ASSOCIATION and RUSS, A. COLIN-. June 20, 1941, No. 7816. [Class 2 (iii) and 15 (ii)] Colouring matters are obtained by oxidizing an aromatic amine, advantageously a pdiamine, in presence of a degradation product of chrome leather, obtained by breaking down the leather by the action of an acid in some cases after a treatment with nitrous acid, and adjusting the pH of the aqueous solution of the degradation product to approximately 3.2. Examples are given of the production of solutions of the degradation products by heating scrap chrome upper leather with a dilute aqueous solution of hydrochloric acid and adjusting the pH to approximately 3-2 by addition of strong caustic soda. In an example of the production of the colouring matters, an aqueous solution containing 4- amino-N-dimethylaniline hydrochloride and sodium thiosulphate is boiled for. 2 hours, potassium bichromate is added and boiling is continued with an addition of dilute sulphuric acid to expel sulphur dioxide and oxidation completed by an addition of potassium chromate, whereupon the precipitated colouring matter is separated and dried. The use as aromatic amines of aniline, N-dimethylaniline and benzidine is also specified. Hot water or hot aqueous alcoholic ammonia extracts of the colouring matter may be used for dyeing cotton, viscose, artificial silk, silk, satin, wool or leather and methods are described of their use for tannin-mordanted cotton and for vegetable-tanned, chrome-tanned or alumdressed or glace leather. The residue from the extraction may be ground alone or in castor or linseed oil for use in paints and lacquers, preferably after admixture with zinc oxide. Alternatively, the initial colouring-matter may be extracted successively with (a) hot methylated spirit for 6 hours to obtain a bluish colouring solution, (b) more methylated spirit for a further 12 hours to obtain a greenish blue colouring solution, (c) hot water for 4 hours, (d) hot 2N hydrochloric acid solution, (e) hot 5 per cent. caustic soda solution ; the acid and alkaline extracts may be mixed in presence of sodium acetate, with or without addition of a precipitate obtained by adding tannic acid to the hot water extract, to precipitate a lake.

IPC: B65B51/04
Filed: 1969-02-13
Abstract: 1,202,504. Container closure; closing resilient containers. A. M. HERZIG, and B. D. MENKIN. 13 Feb., 1969, No. 7928/69. Headings B8D and B8T.  An automatic closure for a squeeze container such as 40 made for example from PVC, polyethylene or a rubbery material, is produced by welding closed one end of a tubular sleeve at 12, punching holes 15 and 16 in the welded area, inserting the legs of a staple 24 into the holes, laterally stretching the sleeve, bending the legs of the staple up to retain the sleeve in the stretched condition, removing the excess welded material and finally bowing the staple to bias the lips in the closure 13 thus formed to a closed position. The above operations are effected by a device comprising a pair of laterally slidable blocks 60 and 65 each carrying a bifurcated anvil member 84 and 90 the limbs 85, 85<SP>1</SP> (not shown) and 91, 91<SP>1</SP> (not shown) of which straddle on upper anvil plate 29 mounted upon a member 72. The blocks also each carry a lower bifurcated gripping jaw 98, 99 and 98<SP>1</SP>, 99<SP>1</SP> the jaws being carried by bell crank levers 96 and 96<SP>1</SP> the rear arms 103, 103<SP>1</SP> of which are biased towards each other by spring 106 and carry cam followers 104, 104<SP>1</SP> actuated by the vertical movement of a head 143. Located between the blocksis a lower die member 30 vertically reciprocated by means of an internally located lever system actuated by a plunger the head 136 of which is actuated by member 141 of head 143. In operation the head 143 is lowered so that the jaws 98, 99 and 98<SP>1</SP>, 99<SP>1</SP> first pivot upwardly to grip the neck against the limbs of the anvil members and the blocks then move outwardly to stretch the gripped neck. Further movement of the head causes the followers 104 to ride over surfaces 152 of the head so that no further stretching occurs, the further movement causing the member 141 to depress head 136 thereby raising the lower die member 30 to bend the legs of the staple into contact with the underside of the neck.

Abstract: 877,535. Luminescent materials. GENERAL ELECTRIC CO. Ltd. March 4, 1958 [March 11, 1957], No. 7949/57. Class 39(1). A crystalline phosphor consists of alkaline earth metal(s), halophosphate(s) activated by copper in the cuprous state with or without manganese and excitable by short or long wave length U.V. radiation of L.P. or H.P. mercury vapour discharge lamps, cathode rays or X-rays. The proportion of copper and of the manganese is within the range of 0.001 to 5.0%, preferably 0.1 to 2.0%, by weight of the total weight of the phosphor, including the activator or activators, calculated from the starting materials used. The phosphor is made by mixing the halophosphate material, or a mixture of compounds which react to produce such material on heating, with a compound or compounds of copper with or without a compound of manganese, and heating the mixture in a weakly reducing atmosphere at a temperature or temperatures within the range of 700‹C. to 1250‹C. The heating can be effected in at least two stages, the second and any subsequent heatings being preferably at a higher temperature than the first, and the material being ground between the heating steps. The weakly reducing atmosphere used can be a mixture of nitrogen and hydrogen in a ratio within the range of 1000 N 2 :1 H 2  to 200 N 2 :1 H 2 , by volume. Several specific examples are described. Specification 877,536 is referred to.

Filed: 1936-03-17
Abstract: 470,716. Race - starting apparatus; games. GRAY, R. G. March 17, 1936, No. 8033. [Classes 132 (i) and 132 (ii)] Race starting apparatus comprises a number of side-by-side stalls having vertically hinged doors or half-doors at the front thereof linked so as to be operated together and adapted to be closed and held closed against spring action by a spring biassed member movable to a position in front of and transversely of the doors against t which it abuts, the holding member being held in position by a releasable catch. The sideby-side stalls 7, Figs. 1, 2, 3, have a common inclined floor 8, a top 10 with a raised transparent portion 11, a rear detachably hinged door 12 and a front vertically hinged door or preferably two half-doors 13 having transparent panels 14. The respective door halves of all the stalls are connected by rods 15, 16, respectively, biassed by springs 17 urging the doors to the open position. Closure of the doors is effected manually by depressing a bar 20 carried by pivotal arms 21, the bar 20 abutting against the front edges of the door halves 13 in their open position and being retracted as it is depressed to close the doors, in which position the bar 20 is held by catches 23 on arms 23<1> pivoted at 23<11>. To start a race, a lever 28 is rocked against the action of a spring 29, whereby cables 25 guided by pulleys 26, 27, are retracted against the action of springs 24 to rock the arms 23<1> and release the catches 23, whereupon biassing springs 22 raise the bar 20 to release the doors 13 which open under the action of the springs 17. Simultaneously an indicator 32 is raised through arms 30, 31, to strike a gong 33 to give a visible and audible indication of the start of a race. The operation of the starting lever 28 also, through link 43 and lever 44 releases the lure 39 or permits it to be clutched to a travelling cable 41 which moves the lure along a rail 40. Each stall may be provided with artificial side walls 34, Fig. 2, vertically pivoted at their forward ends and adapted to be inclined towards each other by operating a handle 38 connected to all the walls 34 through links 36, 37, to urge the stall occupants towards the fronts of their stalls. Retractable wheels are preferably provided for the whole apparatus, the bottom 8 which may be rendered or covered with non-slippery material is hinged to facilitate cleansing operations, and mirrors may be arranged in the stalls to quieten the contestants. When used with model contestants 64, Fig. 5, cranks 47 operated by an external handle through shaft 46 are used to start the models down individual tracks 48, or else the stalls are inclined so that the models start under gravity. The first model to reach the winning post 50 engages a spring biassed lever 51 to release an indicator 58 which in rising to the vertical position moves slides 61 in a guide 6 through a projection 59, thereby preventing complete rising of indicators 58 actuated by subsequent models.

Abstract: 842,380. Moulding machines. DIE CASTING MACHINE TOOLS Ltd., and MILLS, A. R. March 5, 1959 [March 13, 1958], No. 8143/58. Class 87(2). [Also in Groups XXII and XXIX] A moulding machine comprises two moulds 11, 12 brought together by a fluid-pressure piston in a cylinder 15, means responsive to the pressure in the cylinder or the feed thereto to prevent further closing movement of the moulds if the pressure exceeds a predetermined value, and over-ride means 40, 41 allowing the pressure to be exceeded during the initial and final stages of the movement. The mould 11 is closed through toggle linkage by operation of an electromagnet 23 acting against a spring 22 to operate a valve 21. If the mould meets an obstruction, pressure rises in a line 28, and a chamber 24, to operate a switch 27. The switch 27 is short-circuited, however, by switches 40, 41 operated by the moving mould at the ends of its stroke. A power failure causes opening of the moulds by release of the valve 21. Alternatively, it may cause the fluid-pressure to be cut off from the machine.
