Title: Improvements in or relating to Valves.
Inventor: SELF RICHARD ERNST
IPC: F16K3/26
Filed: 1967-08-22
Abstract: 1,164,237. Valves. R. E. SELF. 22 Aug., 1967 [24 Aug., 1966], No. 38683/67. Heading F2V. A valve has two coaxial passages 46, 48 connectible by a passage 52 in an axially slidable spindle 17 to form a constant diameter passage through the valve at an acute angle to the axis. A space 64 surrounding the spindle communicating with the flow passages minimizes unbalanced forces perpendicular to the spindle axis to give ease of operation at high fluid pressures. The spindle is moved axially by a captive threaded handle 19 engaged with the threaded spindle extension 21. The valve housing is formed in two parts between which is disposed a metallic ring 66 with opposed grooves 65 allowing radial movement of the inner periphery. The ring inclined surface 67 contacts the surface 72 of a sleeve 71 which is axially slidable on the spindle during the latter part of valve closing movement. During the latter movement the flange 73 is forced against the resilient seal 74 and thereafter the sleeve 71 moves relative to the spindle until metal to metal contact at 75. In the closed position of the valve the resilient seal is completely surrounded by the ring 66, sleeve 71 and spindle 17.

The elevator 2, fitted with grippers 3 to prevent articles from falling off the elevator, engages a batch and lifts it between the guides 4 into the jaws, the portions 35A of the side guides having been moved aside by cam action to afford passage for the grippers 3 and the batch. Prior to lifting the batch, a prescored carton blank 31 is introduced by belts 22 into a position immediately between the jaws and the batch 30, and as the batch is lifted, the blank is introduced into the jaws by bars 1. The blank is folded into a U-shape with one arm 31c longer than the other, end flaps 31D being formed by the jaws 5, about the batch. An arm 6 engages the batch 30 before the elevator 2 is retracted and moves with the jaws before the carton over-lap 31c engages a guide 7 thus forming the last side of the carton tube. At station 3 plates 8 and 9 fold the second and third end flaps, and a strip of self-adhesive tape, cut from reel 37 by a knife 38, is applied by a dispensing mechanism 12. The plate 9 traverses completely over the end flaps to retain them until the carton engages a fixed folder 10 which folds the remaining end flap. At station 4, the carton is ejected from the jaws by a member 15, the end flaps being held by the side guides 16, and the tape is sealed by a roller 12. Specification 947,356 is referred to.

A method of controlling illuminants for use in colour measurements or reproduction comprises introducing to a varying extent into a light beam containing colours in at least three regions of the spectrum, a colour control filter having greater transmissions in one or more of said regions and lesser transmissions in the other regions, and keeping constant the ratio of the transmitted light intensities in the lesser regions by maintaining in part of the light beam not intercepted by the colour control filter, a connecting light filter having transmissions in the region of lesser transmission of the control filter which are greater than those of the control filter but which have intensities in the same ratio. As shown, light from a source 3 is passed through one, or part of both filters 1, 2 into a mirror box 4 having diffusing sheets 5, 6, on the ends. The primary colour control filter 1 may have a greater transmission in the red and a lesser in the blue and green regions, and the correcting filter 2 may transmit blue and green in the same ratio as the.filter 1. The filters may be mounted to move together on rails 7, 8 and the final light may contain more or less red with the ratio of blue to green remaining constant. A second control filter may be added on the opposite side of the correcting filter, which second control filter may have high transmissions in two regions and low transmission in the third, in the above case of a red control filter, the second control filter would have high transmissions in the blue and green and low transmission in the red regions.

A reciprocating pump 3 in which an eccentric 215 and tappet or tappets 219 for reciprocating the radial piston or pistons 216 have a lost motion connection therewith and a compression spring 221 is provided in each piston tending to move it always in the direction in which it delivers liquid through the outlet passage 208, Fig. 2 (not shown). Liquid is supplied to the reciprocating pump 3 by a continuous delivery gear wheel pump 2 through a passage 4, which is also connected through a pressure regulating relief valve 5 to a reservoir 1. From the reciprocating pump, liquid is supplied through ports 76, 74 of a pressure reducing valve 50 to the larger end chamber 15 of the valve 5 at a constant pressure, and also through a pipe 3<SP>1</SP> to the smaller end chamber 14 of the valve at a varying pressure. When the pressure in the pipe 3<SP>1</SP> exceeds double the constant pressure, the double ended piston 8, 9 moves to the left and allows some liquid from the passage 4 to by-pass to reciprocating pump and be fed to the reservoir through ports 18, 19 of the valve 5 resulting in the maintenance of a steady delivery pressure to load through the pipe 3<SP>1</SP>. Excess delivery to the reciprocating pump 3 is by passed to the reservoir 1 through a spring loaded relief valve 100. The stroke of each piston 216 is variable and determined by the initial movement inwards of the piston, compressing the spring 221 by pressure exerted on the piston crown from liquid in the inlet passage of the reciprocating pump. The cam and bearings of the pump 2 are lubricated from the pressure side thereof, through a restricter 232, Fig. 3A (not shown) leading to the central chamber 203 of the pump 2.

Abstract: Anthraquinone dyes of the formula <FORM:1086084/C4-C5/1> wherein A is the radical of an anthraquinone dye, Z is the simple linkage or a divalent or trivalent bridge member, R1 and R2 are each 1-6 C alkyl or cycloalkyl radicals both of which may be substituted, R3 is -NH2 or a substituted or unsubstituted C1-6 alkyl radical, X is an anion and wherein R1, R2 and the N atom, R1, R2, R3 and the N atom or R1, Y, Z and the N atom may form a heterocyclic ring system, are produced by the reaction of 1 mole of a compound A-Z-Y-E wherein E is a group which can be split off to give the anion of an acid, with 1 mole of a compound <FORM:1086084/C4-C5/2> in vaporous form.  The reaction may be accomplished in the presence of an inert gas, e.g. N2, the ratio of N2 to amine or hydrazine compound may be 25:1 to 1:25, preferably 4:1 to 1:1 by volume.  The preferred amine or hydrazine compounds are asymmetrical dimethyl or diethyl hydrazine, trimethyl- or triethylamine, pyridine 1,4-diaza-bicyclo-(2.2.2)-octane and N-amino- or -alkyl-pyrrolidine-piperidines, -piperazines or -morpholines. Specified radicals E are -OCOCH3, -OSO3H, -SO3R, where R is a substituted or unsubstituted hydrocarbon radical, -SH or, preferably -Cl or Br.  The reaction may be accomplished by conducting the vapour of the hydrazine or amine from an evaporating apparatus into a reaction vessel so that it permeates the interposed anthraquinone compound; the excess vapour is condensed immediately and continuously redirected to the evaporator.  The dyes are suitable for dyeing or printing fibres of cotton, regenerated cellulose, wool, silk, polyamides, polyesters, polyethylene and acrylonitrile polymers and copolymers, polyethylene films and paper in red, blue and green shades.
