Title: Complex metal compounds of water-insoluble monoand dis-azo-dyestuffs and processes for their manufacture
IPC: C09B67/00
Filed: 1961-05-01
Abstract: The invention comprises the complex metal compounds of water-insoluble azo dyes of formula <FORM:0981193/C4-C5/1> wherein R1 and R2 are hydrogen atoms or alkyl or aryl radicals which may be combined to form an isocyclic ring, A is the radical of an arylamide of an aromatic or heterocyclic o-hydroxycarboxylic acid or of an acylacetic acid, n is 1 or 2 and the benzene nucleus a may be substituted by groups which do not impart water-solubility.  The complexes are prepared by coupling a diazotized 5-aminoquinoxaline with a suitable coupling component and treating the resultant dye with a metallizing agent such as a salt or complex compound of copper, cobalt, nickel, manganese, iron, zinc, chromium, aluminium or titanium. The dyes may also be prepared on the fibre (see Division D1).  The dyes may be used to dye nitrogenous fibres and to colour in the mass materials such as polyamides, polyurethanes, polyesters, acetylcellulose polyacrylonitriles and polyolefines.  In Example 3 the dye 5 - amino - 2,3,7 - trimethyl - quinoxaline -->2,3-hydroxynaphthoylaminobenzene is prepared and treated with an aqueous solution of copper sulphate and triethanolamine.ALSO:Complex metal compounds of water-insoluble azo dyes of formula <FORM:0981193/D1-D2/1> are prepared on the fibre by the usual processes.  In the formula R1 and R2 are hydrogen atoms or alkyl or aryl radicals or together form an isocyclic ring, A is the radical of an arylamide of an aromatic or heterocyclic o-hydroxycarboxylic acid or of an acylacetic acid n is 1 or 2 and the benzene nucleus a may be substituted by non-water-solubilising groups.  The metal-free dye may be formed on the fibre and the dyeing then treated with a metallising agent or the coupling component applied to the fibre which is then developed in a bath containing a diazotised 5-aminoquinoxaline and a metallising agent.  Specified fibres are wool, silk, synthetic polyamide, acetyl cellulose or polyvinyl alcohol fibres or, in particular, cotton.  Specified metallising agents are the salts and complex compounds of copper, cobalt nickel, iron, manganese, chromium, zinc, aluminium or titanium. In examples: (1) cotton fabric is padded with an alkaline solution of 2-(21, 31-hydroxynaphthoylamino)-naphthalene, centrifuged and developed in a solution containing diazotised 5-amino-2, 3, 7-trimethylquinoxaline and copper sulphate to give a red dyeing; (2) describes a similar process but wherein the dye is prepared on cotton and then coppered. Further dyeings are specified in a Table.

Title: Digital-to-analog converter with zero offset
IPC: G05B19/4093
Filed: 1962-04-25
Abstract: 975, 737. Electric selective signalling systems. INDUCTOSYN Ltd. April 25, 1962 [May 10, 1961], No. 15780/62. Heading G4H. [Also in Division H2] In an apparatus for positioning a machine tool, allowance for zero offset is made. In Fig. 5, the zero offset of a reference mark 149 on the workpiece is 08. 7500 and the desired work-point 151 is 18. 2946 from there. These two values being set on summing switches, the apparatus derives their analogue sum, which signal is compared with a reference signal. When the amplitude difference is zero the point 151 is below the tool. The numbers are set up on six switches 130, Fig. 1, which each have two scales, as Fig. 8. Corresponding digits in the two numbers are set up on the same switch, the zero offset being set on the inner scale and the work-point on the outer. Each switch is so devised that it adds the digits set on it, resulting in a corresponding movement of the switch shaft (see Division H2). The switches control the selection of tapping points on transformers in coarse, medium, and fine range units 131, 132, 133, and each unit gives an output of amplitude and sign equal to the sine and cosine of the sum of the angles set up on the shafts carrying the switches. Synchro windings 134, 135, 136 receive these three pairs of signals and are sequentially selected by unit 138 for connection to a detector 139, the coarse positioning being performed first. As the workpiece is moved to position the workpiece under the tool the amplitude difference is reduced to zero. Manual or automatic positioning is employed. Specifications 807,219, 839,221, 968,406 and 975,738 are referred to.

IPC: C01B13/22
Filed: 1951-07-09
Abstract: In the production of finely divided metal oxides by decomposing volatile, anhydrous metal chlorides with oxygen at high temperatures with the formation of flames, a suspension of finely divided particles of the chloride, which may be solid or liquid, in an oxygen-containing gas is supplied to a reaction chamber, and therein contacted with an independently-burning auxiliary flame sustained by a separate inflow of combustible gas, at least part of the oxygen necessary for maintaining the auxiliary flame being supplied separately from the reaction mixture, so as to volatilize the chloride particles and to ignite the resulting gaseous mixture and to maintain it in a flaming state.  The suspension is produced by atomizing a liquid chloride by oxygen-containing gases, or by introducing powdered solid material in the gas stream.  The production of oxides of chromium, iron, titanium, zirconium and niobium is mentioned.  Combustible gases which may be used are hydrogen, carbon monoxide, coke oven gas and carburetted hydrogen gases.  The auxiliary flame suitably burns around the stream of the suspended particles, and the methods otherwise described in Specification 661,685 apply.

Title: Improvements relating to snap action electric switches
IPC: H01H13/06
Filed: 1943-10-07
Abstract: 568,620. Retractive switches. MICRO SWITCH CORPORATION. Oct. 7, 1943, No. 16444. Convention date, Dec. 31, 1942. [Class 38 (v)] The operating-plunger of a cantilever leafspring type of snap-action switch, such as that of Specification 419,917, is made in two parts with a spring-connection between them for transmitting the operating force and allowing overtravel of the external actuated part. The leaf-spring comprises a central tension member 14 secured to a post 10 and a pair of side compression members 13 fulcrumed in notches 22 in an anchor-member 11, the plunger acting upon the tension member at a point between the post and notches. The external plunger 39 of hardened steel slides on a cadmium-plated brass sleeve 32 which is a press-fit on a polished stainless-steel pin 24 forming, with the insulating head 25 moulded thereon, the operating part of the plunger. The head 25 has four corner-parts 28 co-operating with the casing- walls to prevent rotation of the head, and a conical preloaded spring 34 is compressed between it and a brass washer 33 slidable on the pin 24. When 39 is depressed, the preloading causes the plunger-parts to move as a whole until head 25 is arrested by anchor 11, any further downward movement of 39 causing the latter to bear on washer 33 and compress the spring 34. The hemispherical tip of plunger 39 allows of operation by sliding contact, and rotation of the plunger equalizes wear thereon. Specification 505,549 also is referred to.

Title: Improvements in or relating to joints for detachably connecting two parts
IPC: B60N2/015
Filed: 1936-06-15
Abstract: 476,807. Fastenings. SILENTBLOC, Ltd., and ANDRE, T. B. June 15, 1936, No. 16617. [Class 44] [Also in Group XIV] In a j oint for de tachably connecting two members, com prising two parts adapted to be brough into engagement by relative longitudinal movement and then locked together by relative rotation, one of the parts is con nected to its suppor by a bushing of rub ber or the like inter posed between, and gripping, concentric portions of the part and the support and so arranged that the part can be rocked so as to stress the rubber as the two members are brought into engagement and the rubber will then cause rotational movement of the part to lock the parts together and maintain them so. In the arrangement shown, the invention is applied to a bayonet joint for attaching a chair leg A to the floor of a vehicle or aircraft. The female member F of the joint is fixed to the floor, and the male member C is attached by a rubber bush D to a support B fixed to the end of the leg A, the rubber D being under compression so as to adhere to the parts B, C ; the rubber may be bonded to these parts if required. A collar C' fixed to the upper end of the member C engages a flange B<1> on the support B through the medium of a rubber washer, to limit axial movement of the parts in one direction ; the bush D bears against the flange B<1> and an enlargement C<1> of the member C to take the axial load on the joint. The lower end of the member C carries a cross-pin E which engages the bayonet slots in the socket F and is extended to form a handle for rotation of the member C on its support. When the members are being brought together, the member C has to be rotated to bring the pin E into line with the entrances to the bayonet slots, and the stress thus produced in the rubber bush D serves to rotate the member C back so as to carry the pin E into the horizontal parts of the slots, the upper edges of which are inclined to produce a wedging action holding the members tightly together. In a modification the assemblage B, C, D is inverted, and the inner member C is fixed to the end of the leg A while the outer member B is knurled for rotation by the fingers and has lateral projections at its lower end to engage the socket, which in this form is elongated in cross-section, the extremities being undercut so that the projections on the member B can pass down inside them and then turn to engage under the cut-away part. The female member of the joint may be mounted in rubber instead of the male member.

Title: Improvements in and relating to engine starting systems
IPC: F02N5/04
Filed: 1943-10-12
Abstract: 570,051. Engine turning-gear. JACK & HEINTZ, Inc. Oct. 12, 1943, No. 16725. Convention date, Sept. 24, 1942. [Class 7 (v)] A starting system comprises an inertia starter unit 10, Fig. 1, mounted on the engine, an electric motor 12 mounted-adjacent but not on the engine, a flexible shaft drive 11 connecting the motor 12 and starter unit 10, a hand crank receiving unit 14, a. flexible shaft drive 16 between this unit and the motor, and may comprise means for lifting the brushes of the motor during a-hand-cranking operation. The flexible shaft 11 terminates in the starter unit 10 in a bevel gear 30, Fig. 6, meshing with a gear 29. The gear 29 is coupled on the one hand to an inertia fly-wheel 33 through a gear train 32, 34, 35, 37 and on the other hand to a jaw clutch member 20, through which the engine is rotated, through epicyclic gearing including planet pinions 28 driving a ring gear 27 solid with a sun-wheel 24 meshing with planet pinions 23 carried by a bracket 22, solid with the clutch member 20, the planet pinions 23 also meshing with a ring gear normally at rest, but provided with an overload release clutch 25. The clutch member 20 is moved into operative engagement with the. engine by a push rod 44 operable manually or electrically. A solenoid 50, when energized, rocks a bell-crank lever 49 to turn a lever 45 rigidly mounted on a shaft 46, the free end of the lever engaging the end of the push rod 44. Manual operation is effected through an arm 48 rigid with the shaft 46. To start the engine, the motor is switched on and when the flywheel has speeded up sufficiently, a second switch is closed to energize the solenoid 50. In emergency, a hand-cranking unit comprising a crank handle 90 and multiplying gearing 91 is pushed on to the hand crank receiving unit 14 and the shaft 16, the motor, the shaft 11 and the fly-wheel 33 are rotated thereby, the brushes in the motor 12 being lifted away from the commutator. For this purpose, the brushes 67, Fig. 9, are normally pressed on to the commutator 69 by spring-pressed fingers 70 mounted on shafts 76 rigid with arms 73 carrying insulated cam rollers 74. Cams 75 engage the rollers to lift the fingers 70 off the brushes or, through hooks 77, to make the fingers 70 draw the brushes away from the commutator positively. The cains 75 are linked together for simultaneous operation by a control wire terminating, in the case of an aircraft engine, in the pilot's cockpit and are turned beyond a dead-centre position, a small return movement of the control permitting the springs to return the brushes to their operative positions. When the fly-wheel has been cranked up to the desired speed, the arm 4 is pulled by a control 47 adjacent the crank handle to engage the clutch member 20 with the engine.
