Title: Improvements in and relating to fluid flow control valves
Inventor: LEEK HERBERT BENTLEY
IPC: F16K41/12
Filed: 1964-08-04
Abstract: 1,038,237. Valves. SAUNDERS VALVE CO. Ltd. July 15, 1965 [Aug. 4, 1964], No. 31730/64. Heading F2V. A needle valve 10 has a diaphragm 13, preferably metal, and a confined body 14 of elastomeric material or a silastomer whereby operation of the handle 18 actuates the valve by the action of the material 14 acting through the diaphragm. The material 14 has the same property as a fluid under compression to distribute the load over the surface of the diaphragm. The diaphragm prevents leakage and the material also acts as a seal if the diaphragm ruptures. The handle acts through a nylon pad 20, a steel compression disc 21 and an anti-extrusion disc 23.

Title: Improvements in or relating to photographic colloid-silver halide emulsions
IPC: G03C1/053
Filed: 1952-12-16
Abstract: 722,397. Photographic colloid-silver halide emulsions. DU PONT DE NEMOURS & CO., E. I. Dec. 16, 1952 [Jan. 11, 1952], No. 31889/52. Class 98 (2). An emulsion containing an anti-plumming or anti-bronzing compound has dispersed therethrough a polymeric amino-nitrogen-containing material which is insoluble in water and dilute alkalis but soluble in 1 per cent acetic acid. Preferably the anti-plumming or anti-bronzing compound is in finely-divided form, and it is still more preferred to have this compound dispersed in particles of the polymeric aminonitrogen-containing material, in which case the latter prevents washing out of the former during development but permits release thereof in acid-stop or acid-fixing treatment, and so allows for use of less than a third of the usual amount of the compound to produce anti-plumming or anti-bronzing effects. In the preferred aspect of the invention the emulsion is used for printing papers, but use in portrait and lithographic film and for seismographic and spectrographic line recording is referred to. The emulsion colloid may be gelatine, or numerous other materials as described with reference to Specifications 598,477 and 600,023. 1-phenyl- 5-mercaptotetrazole is specified as anti-plumming compound in five examples, and in five comparison tables which indicate contrast and presence or absence of plumming under various conditions; other 5-mercaptotetrazoles as of Specification 561,875, and thiouronium salts as of Specification 613,400 may be used. The polymeric amino-nitrogen-containing materials are such as are capable of forming hard resin-like films, although they are not so used in the invention, and they are of three classes: (1) cellulose derivatives; (2) synthetic resins; (3) protein derivatives, all of which are provided with sufficient amino-nitrogen groups to give the required solubility characteristics and all of which are described in Specification 537,232. In the five examples the l-phenyl-5-mercaptotetrazole anti-plumming compound and polymerized diethylaminoethyl methacrylate, the preferred amino-nitrogen-containing material, in solvents including ethyl and methyl alcohol and toluene, together with a dispersing agent as of Specification 592,676, are blended into a chloro-bromide emulsion to produce the desired dispersed particles, contact type procedure is followed for further preparation and coating, and after exposure processing is effected in a specified metol-quinol developer and acid fixer; and drying is effected on hot and on cold ferrotype plates for evaluation of plumming. The anti-fogging property of the l-phenyl-5-mercaptotetrazole anti-plumming compound is referred to.

Title: New metalliferous monoazodyestuffs containing halotriazine residues and their manufacture and use
IPC: C09B62/095
Filed: 1958-10-10
Abstract: The invention comprises metallised monoazo dyes containing one atom of chromium or cobalt bound in complex union to two monoazo dye molecules of formula <FORM:0896785/IV (c)/1> wherein R1 is a benzene residue, R-OH is the residue of a diazo component of the benzene series bound to the azo group in o-position to the hydroxyl group and containing a halogenated 1 : 3 : 5-triazinylamino group and n is a whole number.  The halotriazine residue may contain two halogen atoms or one halogen atom and as substituents on the remaining carbon atom of the triazine ring, an etherified hydroxyl or mercapto group or a primary, secondary or tertiary amino group.  The dyes are prepared by condensing a 1 : 2-chromium or -cobalt complex of an aminoazo dye of the above formula but wherein R is substituted by a primary or secondary amino group, with a trihalotriazine and, if desired, with an organic hydroxyl or mercapto compound, ammonia or a primary or secondary amine, in either order.  The dyes may be used to dye superpolyamide fibres, wool, silk or leather, but especially cellulose in the presence of an acidbinding agent in blue shades.  In an example the dyestuff 6-acetylamino-2-amino-phenol-4-sulphonic acid --> 2 - phenylamino - 5 - naphthol - 7-sulphonic acid is prepared, heated with aqueous sodium hydroxide solution to saponify the acetylamino group and the aminoazo dye converted into the 1 : 2-chromium complex which is condensed with cyanuric chloride.

Filed: 1948-12-15
Abstract: 648,202. Actuation of switches; thermal switches. BRITISH THERMOSTAT CO., Ltd. Dec. 15, 1948, No. 32478. [Class 38(v)] A switch-actuating mechanism comprises spring blade 12 held in a bowed, tensioned condition and engaged by an operating member acting along the chord of the arc defined by the blade, such that movements of said member modify the degree of curvature of the blade, and means acting radially of the blade for transmitting movements thereof to a snap-action switch. The mechanism is shown applied to a thermostatically-operated switch. The operating member comprises a thermal element of the rod-and-sleeve, differentialexpansion type, the movable rod 7 of which extends through the wall of a casing 1 in which is mounted the snap-action switch 9 and arms 14 carrying the blade 12 at their ends. One end of the blade engages an abutment 16 and the other the rod 7. Amplified movement of the rod 7 is transmitted from the centre of the blade to the switch arm 9a by a. dolly 17. The differential of the switch may be varied by adjusting the abutment 16 so as to vary the curvature of the blade. Consequent alteration of the location of the switch may be effected by adjustably mounting it in the casing. The blade-tension adjusting means may be coupled to the switch so that the latter follows adjustments of the blade. Alternatively, the switch may be fixed and the dolly adjustable in length, e.g. telescopic, or a series of different size dollys may be used to cover a range of adjustments. Bellows may replace the thermal element shown, or the switch may be operater by a pressure-responsive element. A number of switches may be operated by a common operating member through a crosshead carrying separately-adjustable abutment means.

Doping of selected areas of an oxide covered semi-conductor crystal is effected by depositing an additional material on the oxide which, at the diffusing temperature concerned, forms with the oxide a vitreous mesh permeable to the material to be diffused; the additional material may comprise the dopant or this may be applied separately. In one example, an N-type silicon wafer is covered with a 1Á layer of SiO 2  and a 0À25Á layer of Na 2 O is then deposited on selected areas of the oxide, the amount being chosen to be appropriate for the Na 2 O-SiO 2  system eutectic. Diffusion of the desired impurity is then effected through the permeable eutectic areas. In another example, B 2 O 3  is used as the additional material and in this case the boron itself acts as the dopant. Alternatively, FeO or MnO may be used to form the eutectic, the iron or manganese serving to form recombination centres in the silicon; other materials include PbO which may be used for the gettering of heavy metal ions from the silicon, and K 2 O or a salt such as Na 2 F 2 . It is also possible to utilize a three or multi-substance system to form the liquid phase for example by using an alkaline earth metal oxide and an alkali metal oxide, e.g. SiO 2  : CaO : Na 2 O. Other semi-conductor materials such as germanium and A 2 B 6  or A 3 B 5  compounds such as gallium arsenide may be used; in these eases foreign oxide layers such as SiO 2  are used.
