Abstract: 484,432. Actuation of switches. JONES, C. April 2, 1937. Nos. 9359 and 11847. [Class 38 (v)] [Also in Group XXXV] A switch comprises a fixed insulated support 2 carrying contacts, P, I, S for several circuits, between which two rods 1, 13 move axially. Rod 1 is loosely threaded and rod 13 fixed to an operating cable 3 whereby movement of the cable to the left causes closure of all switches but return movement under spring action only causes opening of the switch S on the rod 13. A knob 22 provides for manual opening of the switches P and I on the rod 1. In another arrangement, Fig. 8. the switch comprises a disc 27, carrying contacts IC; S, which is mounted so as to oscillate on a shaft by operation through a pawl 29 on an operating rod 3. The switches IC and S co-operate with stationary contacts 25. A segmental member 28 mounted loosely in the bore of the disc 27 carries contacts IM, P which co-operate with corresponding fixed contacts 25. Movement of the pawl 29 to the left causes clockwise movement of disc 27 which carries the member 28 with it so as to close all the switches. Release of the disc 27 causes anticlockwise return movement thereof opening switches IC and S but the member 28 remains in the operated position until re-set manually. Specification 414,113, [Group XXXV], is referred to.

Patent GB-494904-A (GB)
Title: Process for the manufacture of vat dyestuffs
IPC: C09B6/00
Filed: 1937-04-02
Abstract: Vat dyestuffs are manufactured by reacting 8 - hydroxy - 1 : 2 - naphthophenazinecarboxylic acid halides with amines of vattable compounds, e.g. of the anthraquinone, anthraquinoneacridone, phthaloylcarbazole or pyridineanthrone series.  Either component may contain further indifferent substituents, 8-hydroxynaphthophenazinecarboxylic acid halides containing additional halogen atoms being particularly suitable.  The reaction is carried out at an elevated temperature in the presence of an indifferent solvent, e.g. chlorobenzene, o-dichlorobenzene or nitrobenzene, in certain cases advantageously in the presence of an acid-binding agent, e.g. an alkali metal acetate.  In examples: (1) 1-aminoanthraquinone is heated in trichlorobenzene with a mixture of 8 - hydroxy - 1 : 2 - naphthophenazine - 41-and 51-carboxylic acid chlorides; the product yields from a hydrosulphite vat yellowish orange shades which become clearer on aftertreatment with chlorine; (2) 1-amino-5-benzoylaminoanthraquinone is similarly treated; the product dyes cotton orange shades; (3) 1 - amino - 4 - benzoylaminoanthraquinone is reacted as in (1) with a mixture of dibromo-8 - hydroxy - 1 : 2 - naphthophenazine - 41-and 51-carboxylic acid chlorides; the product yields orange shades; (4) 1-amino-5-benzoylaminoanthraquinone is employed in the reaction of (3); the product yields golden shades; (5) 6 : 7 - dichloro - 1 - aminoanthraquinone is heated in trichlorobenzene with a mixture of 8 - hydroxy - 1 : 2 - naphthophenazine-31- and 61-carboxylic acid chlorides; (6) 1 : 4 - diaminoanthraquinone is heated in nitrobenzene with the mixture of acid chlorides employed in (3); the product yields orange shades from a currant-coloured vat; (7) 1 : 5-diaminoanthraquinone is similarly reacted; the product yields orange shades from a brown vat.  8 - Hydroxy - 1 : 2 - naphthophenazinecarboxylic acids are obtainable by condensation of b -naphthoquinone - 8 - sulphonic acid with an o-phenylenediaminecarboxylic acid, followed by alkali fusion.  In this way 1 : 2-phenylenediamine yields a mixture of the 31- and 61-acids and 1 : 2-phenylenediamine-4-carboxylic acid a mixture of the 41- and 51-acids.  The products may be halogenated.  Dibromo - 8 - hydroxy - 1 : 2 - naphthophenazine-41- and 51-carboxylic acid chlorides are obtainable by the action of bromine in pyridine on the mixture of 41- and 51-acids referred to above, and treatment of the product with, for example, thionyl chloride.  Samples have been furnished under Sect. 2 (5) of the products obtained by heating a mixture of 8-hydroxy-1 : 2-naphthophenazine-41- and 51-carboxylic acid chlorides in nitrobenzene with : (I) anthraquinone-2 : 1 (N)-11 : 21 (N) -31 - chloro - 61 - aminobenzacridone; (II) the compound obtainable by condensing 5-nitroisatine chloride with 9-chloro-1 : 2-naphthoxythiophene and reducing the nitro group; (III) the diaminoanthanthrone obtainable by dinitration of anthanthrone and reduction of the nitro groups.

Title: Improvements in and relating to the manufacture of viscose
IPC: D01F2/08
Filed: 1948-04-05
Abstract: <PICT:0642270/IV (a)/1> In the preparation of viscose a mixture of cellulose xanthate and aqueous caustic soda is fed through a granulator having a number of compartments each provided with a perforated base and rotating blades, the mixture being continuously fed to the top of the granulator and continuously withdrawn from the bottom, and the rate of feed and the speed of rotation of the blades being such that the mixture offers substantially no resistance to the rotation of the blades of the granulator.  As shown, the granulator consists of a cylindrical shell divided into four compartments 3, 4, 5, 6 by perforated bases 23, 24, 25, 26.  The perforations in the bases successively decrease in size. Compartment 3 is provided with an inlet pipe 7 carrying a pressure gauge.  An outlet pipe 9 is provided below compartment 6.  A power driven shaft 11 extends throughout the granulator and is driven by gearing in chamber 1.  In each chamber 3, 4, 5, 6 the shaft bears a collar 16 carrying three rectangular radial blades 17, each tilted slightly away from the vertical, and the collars are so fixed that there is a minium distance between the blades and the perforated bases.  The exposed part of the shaft is protected in each chamber by a shield 18. Chambers 1 and 2 are closed except for the bearing 19 in which the shaft rotates and a gland 21 in the base of chamber 2.  This chamber (2) acts as a safety trap, preventing oil from the oil-seal 20 around the bearing 19 from contaminating the mixture in chamber 3, and also preventing contamination of the gearing by the xanthate-caustic soda mixture should the pressure within the granulator build up and force the mixture through the gland 21.  The cellulose xanthate and caustic soda may be premixed before being fed to the granulator.  An example of the operation of the device is given.  U.S.A. Specification 1,794,214 is referred to.

Abstract: 1500631 Analyzing machine coolant GENERAL ELECTRIC CO 7 March 1975 [8 April 1974] 9629/75 Heading G1B [Also in Division B1] A dynamoelectric machine has apparatus for sampling and analyzing thermal decomposition products given off into a gas coolant in the machine, the apparatus being connected by an inlet to a tap (51) on the high pressure side of the machine and via an outlet (53) to a tap on the low pressure side of the machine and having between the inlet and outlet a gas chromatography column for receiving a portion of the coolant, a detector connected to the downstream end of the column, a sampler device upstream of the column and means upstream of the column for selectively supplying coolant from the machine through the sampler device in the sampling mode and a carrier gas through the sampler device in the analysis mode. In the sampling device shown, coolant tapped off from the high pressure side of the supply passes in the sampling step through valve B, sampling device 55 which may be as described in Specification 1444315 and comprise a heatable absorbent for the decomposition products, valves E and G, gas purifier 61, valve F and the column 57, while in the analysis step the coolant passes  through valves A and G, purifier 61, valve C, in the reverse flow direction through sampling device 55 where the absorbent is heated to free the decomposition products, through valve D to the column. Operation of valve B may be initiated by a signal from an ion chamber detector connected to detect the presence of pyrolysis products in the coolant and the ion chamber signal may also operate an alarm signal. In an alternative embodiment Fig. 3 (not shown) the coolant from the machine is split into two streams, one passing through a heater which breaks down any particulate and high molecular weight products then to a chromatographic sampling valve, the latter valve being fed also with the purified second stream of coolant which acts as carrier gas.
