Patent GB-700210-A (GB)
Title: Manufacture of azo-dyestuffs
IPC: C09B43/10
Filed: 1951-07-19
Abstract: The invention comprises dyestuffs of the formula <FORM:0700210/IV (c)/1> where R1 is a benzene residue containing a p-alkoxy group, Z is azo or azoxy and R2 is a benzene residue containing a further benzene ring attached to it in the m- or p-position either directly or through a bridge member.  R1 and R2 are preferably free from solubilizing groups.  The dyestuffs may be made by (1) coupling diazotized 4-nitro-4\sv-aminostilbene-2 : 2\sv-disulphonic acid with a phenol, alkylating the hydroxyl group and condensing the product with 2 : 5-diaminobenzoic acid; (2) coupling and alkylating as in (1), then reducing the nitro group to amino diazotizing and coupling with anthranilic acid; or (3) coupling diazotized 4-nitro-4\sv-aminostilbene-2 : 2\sv-disulphonic acid with anthranilic acid, acylating the amino group, reducing the nitro group to amino, diazotizing, coupling with a phenol, alkylating the hydroxyl group and finally hydrolysing the acylamino group.  The azoazoxy or disazo dyestuff resulting from one of these three processes is then diazotized and coupled with the appropriate pyrazolone.  The anthranilic acid is preferably coupled as its w-methanesulphonic acid and then hydrolysed.  The products are suitable for dyeing and printing wool, silk, leather, cotton, linen and regenerated cellulose. They be metallized in substance, in the dyebath or on the fibre, e.g. by the processes of Specifications 455,274 and 619,969; suitable metals are copper, chromium, iron, nickel and cobalt. The preparation of dyestuffs is exemplified where R1 is p-methoxyphenyl and R2 is 4-phenylphenyl, 4-(p-aminophenyl)-phenyl, 4-(p-acetylamino)-phenyl, 3- or 4-benzoylaminophenyl and 3-carbanilidophenyl.  It is also stated that the two rings in R2 may be joined by oxygen and that the outer one may be substituted, e.g. by alkyl, alkoxy, halogen or methylamino. 1-(p-phenoxyphenyl)-3-methyl-5-pyrazolone is specified as coupling component.  In a further example cotton is dyed red-orange with the dyestuff where R1 is p-methoxyphenyl and R2 is 4-phenylphenyl, with after-coppering.

Abstract: 992,298. Vertical steam boilers; superheaters. FOSTER WHEELER Ltd. April 24, 1964 [May 1, 1963], No. 17204/63. Addition to 929,682. Heading F4A. The vertical steam boiler described in the parent Specification is modified in that the vertical bundle of U- tubes instead of being connected to a pair of headers or to a tube plate is connected to a single header subdivided into an inlet and an outlet compartment by an internal partition. In the form shown, an upright casing 10 contains within its lower portion a bundle of inverted U- tubes consisting of two outer banks such as 26 between which is located a middle bank 24, the ends of the tubes being connected to a horizontally disposed header 50 divided internally by a partition 52 into a heating medium inlet chamber 54 and outlet chamber 58. A cylindrical baffle 18 surrounds the outer banks to provide an annular downcomer space 20 into which feedwater is directed from a pipe 16 and an inner riser space 22 wherein steam is generated as the ascending water column passes over the outer banks, steam-water mixture flowing into separators 23 whence water returns to the downcomer space whilst steam flows through driers 34 into an upper space 35. The middle tube bundle is enclosed by spaced inner and outer coaxial baffles 38, 30, the lower end of the inner baffle terminating at a distance above the header 50 whilst its upper end is continued as an extension 48 forming a steam outlet pipe. The lower end of the outer baffle 30 is welded to the header 50 whilst its upper end is continued as an extension 42 leading into the steam space 35. Steam from the space 35 flows downwardly in the annular space between baffles 38, 30 and rises in contact with the bundle 24 becoming superheated and discharges to the point of use through the extension pipe 48.

Title: Hydraulic control valve
IPC: F15B13/04
Filed: 1975-04-25
Abstract: 1462846 Valves DEERE & CO 25 April 1975 [26 April 1974] 17333/75 Heading F2V In a control valve 12 for actuating a pistoncylinder 36, a valve member 70 controls the flow between an inlet 26 and a work port 38 and a valve member 86 controls the flow between work port 34 and a reservoir chamber 18, both valve members being slidable on a hollow valve stem 58 and biased into contact with its respective seat 72, 46. A piston 60 integral with the valve member 70 separates the inlet 26 from a lower closed chamber apart from a restricted communication through a piston slot and a gap in a split sealing ring. The closed chamber communicates with the reservoir chamber 18 via the hollow stem 58 and a pilot valve having a spring loaded closure member 98 actuated by an arm 108 on a rotary shaft 106. When the shaft is operated so that closure member 98 opens communication between the reservoir chamber 18 and the lower closed chamber the pressure imbalance across the piston 60 causes it to move away from its seat to allow flow from the inlet to the work port 38 via check valve 74. The valve stem is also moved by the piston 60 to move the valve member 86 off its seat to communicate the work port 34 with the reservoir chamber 18. The amount of movement of piston 60 required before the valve member 86 is moved by the ring 92 on the stem 58 is adjusted by shims 64. A second similar valve controls the flow of fluid from the inlet to the work port 34 and the flow from work port 38 to the reservoir chamber. Additional actuating means are provided to move both valve stems downwards to simultaneously connect both work ports to the reservoir chamber and allow the motor to "float". The means comprise a piston 114 mounted above the reservoir chamber and acting on the end of each valve stem so that simultaneous actuation of the pistons moves the valves to "float" position. In a modification the pilot valve for normal operation of each valve is electromagnetically operated.

Abstract: 292,517. Maatschappij tot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen. June 20, 1927, [Convention date.]. Loose-weight apparatus.-In an automatic or semi-automatic weighing scale of the type wherein supplementary weights are provided for increasing the weighing capacity, the supplementary weights are successively placed upon or removed from a support connected to the weighbeam, by means of a single wedge-shaped member operable from the exterior of the scale. The weighbeam 6 carries a pan 7 steadied by usual check link mechanism and provided with holes 9 for the reception of the supplementary weights 8. Below the pan is a wedge 13 formed on the end of a rod 11 slidable into various positions determined by notches 11<a> and a ball catch 12. When the rod 11 is pressed in one or more of the supplementary weights are raised by vertical rods 14 and are retained out of contact with the weighing mechanism. The return movement of the rod 11 returns the supplementary weights to the pan 7. Covers 7<a> prevent the weights from becoming displaced from the rods 14. In a modification, the rod 11 bears a rack which rotates a face cam situated beneath a circular arrangement of the rods 14. The movements of the rod 11 thus cause the cam to raise or deposit the supplementary weights successively to vary the weighing capacity.
