Title: Process for the manufacture of dyestuffs
IPC: C09B47/067
Filed: 1936-07-18
Abstract: Metal-free phthalocyanines and alkyl derivatives thereof are made by heating phthalonitrile or substitution products thereof with Grignard reagents, i.e. alkyl, cycloalkyl, aryl or aralkyl magnesium halides, preferably in presence of a tertiary amine, e.g. pyridine or quinoline, and hydrolyzing the intermediate products thus obtained by means of sulphuric acid. Dimethylphthalocyanines are obtained from methyl magnesium halides and mixtures of phthalocyanines and dialkylphthalocyanines from ethyl and propyl magnesium halides. Other Grignard reagents yield the known metal-free phthalocyanines. The new alkylphthalocyanines can be sulphonated and/or halogenated. The alkyl compounds are more greenish.  In examples, (1) a mixture of magnesium methyl iodide and phthalonitrile in ether and benzene is allowed to stand some hours; thereupon the excess of solvents is removed, the residue heated to 80 C DEG ., dissolved in quinoline and the whole heated to 125-130 DEG  C.; the complex quinoline methyl magnesium compound is the hydrolyzed with sulphuric acid yielding dimethylphthalocyanine which when dispersed is suitable for colouring wallpaper, or for graphic prints or for the colouring of rubber; the sulphonic acid obtained by the reaction of 20 per cent oleum may be used for dyeing cellulose material and for colour lakes; bromination in nitrobenzene gives a greener product; (2) ethyl iodide or isopropyl bromide is used instead of methyl iodide above whereby a mixture of metal-free phthalocyanine and the corresponding alkyl phthalocyanine is obtained; (3) n-butylbromide, cyclohexylchloride, benzylchloride or brombenzene are used instead of methyl iodide above yielding metal-free phthalocyanine.ALSO:Dimethylphthalocyanine obtained from phthalonitrile and magnesium methyl iodide is stated to be suitable for the colouring of rubber.

Abstract: 951,145. Diffusion pumps. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 17, 1962 [June 2, 1961], No. 20015/61. Heading F1E. In a diffusion pump, a reheater 13, formed of material having good thermal conductivity, extends above the liquid surface in the vapour path and is in good thermal conducting relationship with the heater 8 so as to tend to vaporize any drops of liquid which are carried in the vapour from the boiler. An electrical resistance heater 7 heats the working liquid through heater 8 and reheater 13 has apertures 14, through which the vapour may diffuse. In modifications the reheater 13 may have longi-  tu dinal, helical or circumferentially fins which may be surrounded by a cylindrical shield. In a further modification a tube extends from the top of the reheater 13 into the duct 3 and is formed at its upper end with a second jet and with apertures at its lower end. The reheater may be welded or brazed to a plate to which is attached an immersion heater. The upper surface of the plate may be domed. In another embodiment the heater projects into the reheater through a central aperture formed in the plate 8. The reheater may extend past one or more jets in a multiject pump and may be applied to each duct in a multiduct pump. Specification 889,362 is referred to.

Abstract: 1,198,563. Non-linear resistors. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 26 April, 1968 [27 April, 1967], No. 20072/68. Heading H1K. A non-linear resistor comprises a sintered body 1, consisting essentially of zinc oxide, having two main faces, one of which has an electrical resistivity higher than that of the other and two electrodes 2, 3 applied to these faces of the body, one making a non-ohmic contact with the face having a higher electrical resistivity and the second making either an ohmic or non-ohmic connection to the other surface. The low resistivity face is obtained by removing over one main face the high resistivity surface layer of the body formed during sintering in an oxidizing atmosphere. The body contains 90 to 99.95 mol. per cent of zinc oxide and at least one oxide from the group consisting of iron oxide, aluminium oxide, bismuth oxide, magnesium oxide, calcium oxide, nickel oxide, cobalt oxide, niobium oxide, tantalum oxide, zirconium oxide, tungsten oxide, cadmium oxide and chromium oxide. The non-ohmic electrode is substantially silver with small amounts of lead oxide, silicon dioxide, boron oxide, bismuth oxide, calcium oxide and cupric oxide, and is painted on to the body. The ohmic electrode may be an evaporated film of aluminium, zinc, tin or indium, an electroless or electrolytic plated film of silver, copper, nickel, zinc or tin or a metallized film of copper, tin, zinc or aluminium.
Patent GB-630942-A (GB)
Title: Remote indicating system
IPC: G01F1/24
Filed: 1947-07-25
Abstract: 630,942. Electric indicating systems. FISCHER & PORTER CO. July 25, 1947, No. 20094. Convention date, Feb. 8, 1945. [Class 40 (i)] A device for the remote indication of the movement of an element sensitive to variations in a variable condition consists of a magnetic core capable of being moved by the variable condition inside a multi-winding transformer, thereby modifying the voltages induced in a series of inter-connected secondary windings, which voltages when applied to an indicating device of resultant field type show the position of the core relative to the windings. The embodiment shows its application to a rotameter, wherein the flow of a fluid into a chamber 21 through an inlet 22 raises a float 24 which has a magnetic core 45 attached to the end of an extension tube 44. This tube is surrounded by a series of secondary windings 49, 51, which are further surrounded by a primary winding 53, the secondary windings being connected as shown in Fig. 5 to an indicating unit 64, consisting of two mutually perpendicular coils 66, 67 and a Z-shaped armature 68 of soft iron, pivoted on the axis of coils 66, 67 and provided with a pointer 70 moving over a calibrated scale 71. The armature 68 is energized by a winding 72 connected to an A.C. source 65 which also energizes the primary winding 53. With no flow into the chamber 21, the float 24 is in its lowest position, and the core 45 is fully embraced by winding 49a. The volts induced in winding 49a therefore produce a field associated with coil 66, and the armature 68 will locate itself at right-angles to coil 66, with needle 70 pointing to 0 on scale 71. As the float 24 is raised due to the fluid-flow into chamber 21, the core 45 is successively embraced by windings 49b, 49c and 49d, and the resultant field of the indicating unit 64 changes so that the needle 70 moves in an anti-clockwise direction. The positioning of the secondary windings 49 is such that the angular rotation of the needle 70 is directly proportional to the linear movement of the float armature 45. End effects on the transformer are substantially neutralised by small additional secondary windings 51. The needle may be made to move clockwise by reversing the wiring connections. The apparatus can be adapted for measuring temperature, pressure, velocity, liquid level, &c.

Title: Improvements in or relating to centreless grinding machines
Inventor: JONES JOHN CYRIL
IPC: B24B5/18
Filed: 1961-06-05
Abstract: 1,021,822. Grinding. CHURCHILL MACHINE TOOL CO. Ltd. May 22, 1962 [June 5, 1961], No. 20140/61. Heading B3D. Control apparatus for a centreless grinding machine of the through feed type comprises timing means for initiating a truing cycle for the grinding wheel and suspending the grinding operation after a predetermined interval of grinding, means for recommencing the grinding operation after the truing cycle has been completed and means for providing a compensating feed to the grinding wheel and/or control wheel. The control wheel 3 and its drive are mounted on a slide movable, by a screw and nut mechanism, towards the grinding wheel 2. For fine feed the screw is rotated by an electric motor FCM and for coarse feed the nut is rotated by an electric motor CCM. A hand wheel 39 is provided for manual adjustment. A truing diamond 23 is traversable to and fro across the face of the grinding wheel 2 by an electric motor 22, downfeed of the diamond being effected by motor 24. Workpieces, e.g. needle rollers, are loaded into a rotary bowl feeder hopper 17, driven by motor 18, which discharges them along a work blade 20 between the grinding and control wheels 2, 3, the ground workpieces then passing through a pneumatic gauge head 21. If, due to wear of the grinding wheel, the gauged diameters are persistently oversize an automatic fine compensation feed is applied to the control wheel, this feed being repeated at timed intervals until the diameter is again brought into the permitted tolerance. If, for any unforeseen reason, the gauged diameters are persistently undersize the hopper motor 18 is stopped. At intervals determined by a timer the hopper feed is stopped and after a further short interval, sufficient to allow the workpieces that have already left the hopper to pass the grinding wheel, the truing cycle is initiated. While truing is in progress, coarse compensation is applied to the control wheel, the amount of compensation being set to advance the control wheel by an amount slightly less than the depth of cut of the truing diamond. Thus the first workpieces ground after truing are oversize. An electromagnetic device 25 is included in the shoot 26 through which ground workpieces pass so that the oversize workpieces are diverted automatically to a bin 27 from which they can be returned to the hopper 17 for regrinding. While the workpieces are leaving the grinding throat in an oversize condition the fine compensation feed operates at intervals until workpieces are brought within the permitted tolerance; the electromagnetic device 25 is released and workpieces then pass via shoot 26 into another bin.

Abstract: 651,466. Nails. ELASTIC STOP NUT CORPORATION OF AMERICA. Aug. 1, 1947, No. 20936. Convention date, Jan, 26, 1944. [Class 89(ii)] [Also in Group XXII] Relates to sheet metal hails of the type in which one part is arrested by a head before another part is driven completely home; the parts being so connected that' the latter part is caused to deflect laterally. In one form a blank is split at 12 from the head end as far as 12a, one member 16 is stiffened by longitudinal ribs 26 and 30 and weakened by a transverse rib 28, and the other member has a projection 22 that slides in the rib 26, a notch 20, lug 18, and on offset 32 just below the rib 28. The blank is folded so that the projection 22 is received in the groove formed by the rib 26 and the lug 18 bent to retain the two parts in sliding engagement. The end 10 is bent over at the dotted line a diamond - shaped recess 24 forming a strengthening flllet. The member 16 is curved at the top to provide a driving edge 38. When the head 34, Fig. 2, is arrested, further driving of the edge 38 causes the part 16 to bend at 28 so that the point extends laterally into the material as shown. The head 34 is preferably bent to an acute angle with the shank so that it lies flat in the clinched position. In a modification the edge 38 also has a bent over portion. A blank for a form that has two points that diverge laterally in opposite directions is split from the point at 68, Fig. 7, as far as a hole 66, points of weakness are formed by holes 64 from which slits 54 extend to the head end. The side parts are folded about the lines 80, on opposite sides of the centre part that is stiffened by ribs 88. In a further form a centre member is arrested by its head that is slotted to guide side members that collapse and diverge laterally and outwards. In another form, slit at 152, 154, Fig. 17, the outer parts are bent at the line 158 to form arresting heads extending to one side and the end 172 is bent to the other side to form the driving-head. This is reduced in width so that when the nail is fully driven the arresting heads spring in, over the shoulders formed, preventing withdrawal. Fig. 18 shows a blank in which lugs 212 from the arresting head and the driving-head extends through the slot 210. In a final form the driving end has a hollow domed head attached and this snaps over the arresting head when the nail is driven home. This form is preferably made from brass and is used for securing upholstery.
