Title: Method of and apparatus for lapping valves
IPC: B24B15/08
Filed: 1946-12-18
Abstract: 626,090. Lapping valves. TRIGGS, W. W. (Rockwell Manufacturing Co.). Dec. 18, 1946, No. 37319. [Class 60] A method of lapping the seating surface of valves comprises lapping the movable valve member in its seat in the presence of a lapping compound and at a pressure within the valve body which is at least equal to the rated maximum working pressure of the valve. Preferably the lapping is also carried out while the valve parts are at a temperature at least equal to the rated maximum working temperature of the valve. As applied to the lapping of a lubricated plug valve constructed as in Specification 436,073, [Group XXIX], the member which is normally threaded into the cover plate 16 to force the valve plug 14 against the valve seat 13 is replaced, for the purpose of lapping, by a bushing 19 threaded into the cover plate; a spring 22, adjustable by a screw 26, acts on a pin 23 the head of which carries a ball 24 contacting the valve plug 14; a diaphragm 29 is provided. The operating stem for the valve plug 14 is replaced, for the purpose of lapping, by a sleeve 37 within which is a member 39 having a lug 40 which, through an equalizing part 42, oscillates the valve plug 14. The member 39 has a longitudinal bore and has secured to its upper end an injecting device 56 for the lapping compound; the device 56 is actuated as required to inject lapping compound, which is distributed by the lubricating grooves 33 of the valve. The assembled valve 10 is positioned between conduit sections 57, 58 provided at their ends with valves 63, 64. A cylinder 67 of high pressure fluid is connected by a pipe 66 with the conduit 57, under control of the valve 68. Thus with valves 63, 64 shut and valve 68 open, the desired pressure is built up inside the valve 10. For lapping at subnormal pressure, cylinder 67 may be replaced by a suction pump. For low temperature lapping, the gas may be suitably chilled, and for moderately high temperatures, the gas is heated. For high temperature lapping, the valve is heated by means of a blow torch 70, the valve 63 then being opened. The conduits are lined with suitable refractory material 65, and the apparatus is encased in insulating material 69. Inert gases such as nitrogen or carbon dioxide are used as the pressure fluid. Specification 550,835 and U.S.A. Specifications 1,604,712, 1,604,944 and 2,117,351 also are referred to.

Title: Circuit arrangement for correcting the deflection of at least one electron beam in a television picture tube by means of a transductor
IPC: H04N9/28
Filed: 1970-08-04
Abstract: 1323332 Cathode-ray tube circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 4 Aug 1970 [7 Aug 1969] 37624/70 Heading H4T In a cathode-ray tube raster correction circuit (for pincushion distortion) in which a first winding of a transductor is connected in parallel with at least a portion of the line deflection coils current flowing through which is supplied by a deflection generator having a low internal impedance, the influence of the transductor (a control winding on which is supplied from the frame deflection circuit) on the line deflection current is increased by connecting a predominantly inductive impedance in series with the deflection generator. Fig. 1, shows one embodiment in which the winding 11 of a transductor (the control winding 12 of which is connected to the frame deflection circuit via terminals 14, 15) is connected in parallel with the line deflection coils 8, 9 and an inductive impedance, comprising a convergence circuit 17 is connected in series, via an isolation transformer 20, between the deflection coils and the line deflection generator comprising transistors 1, 2 and line transformer 7. With this arrangement the (transformed) impedance of the convergence circuit 17 increases the (effective) internal impedance of the deflection generator and enhances the control effect of the transductor. Also, since the corrected line deflection current flows through the circuit 17 convergence correction is improved, particularly at the corners of the screen in tube having a large deflection angle. A further increase in the (effective) internal impedance of the deflection generator may be provided by the series connection of the linearity control 21. Fig. 2, shows a modification in which the convergence circuit 17 is connected between earth and one end of winding 3 on transformer 7 one end of transductor winding 11 together with the emitter of transistor 2 also being connected to earth. This is equivalent to connecting winding 11 across approximately onehalf of the deflection generator and for correct operation winding 11 is proportioned such that the current flowing through it is approximately twice that operative in the circuit of Fig. 1. This larger current also flows through the convergence circuit 17 and results in improved convergence correction at the corners of the screen. An additional winding 24 having the same number of turns as winding 3 is added to transformer 7 to provide the same operating conditions for transistors 1, 2 as obtained in the circuit of Fig. 1. Resistor 5 in both circuits serves as a protective device for the transistors in the event of an inadmissible load (e.g. tube flash-over) on the ETH which is provided by winding 6.

Title: New colouration process for cellulosic textiles
IPC: C09B62/537
Filed: 1956-12-14
Abstract: Cellulosic textile materials are dyed or printed by applying a dyestuff, e.g. an azo, nitro, anthraquinone or phthalocyanine dyestuff, which contains at least one solubilizing group, such as a sulphonic acid group, and at least one -SO2R group, in which R represents a beta-chloroethylamino or a beta-bromoethylamino radical, and also applying before, together with or after the dyestuff, an acidbinding agent such as a caustic alkali, sodium carbonate or bicarbonate, trisodium phosphate, sodium metasilicate or hydrated magnesium oxide.  The dyestuff solutions or pastes may contain the usual adjuvants such as sodium chloride, sodium sulphate, urea, sodium alginate, cellulose ethers, starch, locust bean gum or a water-in-oil or oil-in-water emulsion.  The dyestuff and/or acid-binding agent solutions may be applied at temperatup to the bolres in.  When the dyestuff and the acid-binding agent are applied in succession a drying operation may be applied between the two treatments. Fixation of the dyestuff may be effected by drying alone, or by heating or, in the case of printing, by steaming.  In the case of printing, other dyestuffs such as leuco esters of vat dyestuffs and dyestuffs obtained by reacting colouring matters containing halogenomethyl groups with tertiary amines or thioureas may be printed alongside.  Numerous examples of dyeing and printing (including one of discharge printing with a reducing discharge) are given.  The dyestuffs may be obtained by treating an azo, nitro, anthraquinone or phthalocyanine dye containing a plurality of sulphonchloride groups with b -chloro-(or bromo-) ethylamine. Nitro dyestuffs may also be obtained by reacting an o-chlornitrobenzene carrying a b -chlorethylsulphonamide group with a primary aromatic amine carrying a solubilizing group, such as 4-aminoanisole-3-sulphonic acid.  Azo dyestuffs may also be made by diazotizing primary amines containing -SO2R groups, such as m-aminobenzenesulphon-b -chloro-(or bromo-) ethylamide or aniline 3 : 5-di-(sulphon-b -chlorethylamide), with various coupling components, many of which are specified.

Abstract: A traveller for ring-spinning comprises a ring-engaging part of one material receiving a replaceable yarn-engaging part of another material, the materials being chosen for their capability of withstanding wear in relation to the materials they engage.  For a ring comprising a vertical member with a lower enlargement, (42, Fig. 2, not shown), the traveller comprises a plastics member (28) with a groove to receive a yarn-hook of steel &c. which is shaped to extend over the upper part of the ring.  The member (28) is shaped to be retained on the enlargement when the hook fails through wear.  For a ring comprising a horizontal flange, Fig. 8, not show, the ring-engaging member is shaped to conform with the curved inner edge of the ring, and the yarn-engaging member is a hook which extends over, but does not engage, the other part.  In Fig. 2, the flange is of sintered material, and is shaped to accommodate a wick between it and the ring-holder, which communicates with an oil-reservoir by a channel in the holder.
