Title: Improved alkali baths for metal treatment
Inventor: SHAW RICHARD ELLIOTT
IPC: C23C22/73
Filed: 1957-01-30
Abstract: Metals, such as steel, aluminium and zinc and their alloys, are cleaned or etched by immersion in aqueous alkali having a layer of liquid saturated hydrocarbon floating on its surface.  The alkali and hydrocarbon may contain a surface-active agent, e.g. an ethylene oxide/fatty alcohol condensation product or a secondary alkyl sulphate.  Specified alkalis are sodium hydroxide, orthosilicate, carbonate and chromate.  Since the hydrocarbon reduces fuming of hot alkali baths, it is advantageously dyed to give warning that the baths are hot.  Concentrates suitable, on dilution with water, for making up the baths are disclosed.ALSO:Metals, such as steel, aluminium and zinc and their alloys, are cleaned or etched by immersion in aqueous alkali having a layer of liquid saturated hydrocarbon floating on its surface.

Title: Improvements in and relating to machines for making wire helixes
IPC: H01J19/00
Filed: 1927-02-09
Abstract: 265,973. British Thomson-Houston Co., Ltd., (Assignees of Flaws, J.) Feb. 10, 1926, [Convention date]. Electric fittings. - In a machine for making grid electrodes such as those used in thermionic tubes, wherein wire coils are secured to one or more longitudinal support-wires, the supports are carried on a mandrel and the turns of the coiling- wire are laid in notches in the support-wire or wires, the notches being then closed over to secure the wire in position. The machine comprises a bed 1 carrying a headstock 4 and tailstock 3, the headstock spindle 5 being driven from a sprocket 6 through a friction clutch 7 which is actuated through rods 8, 9, from a lever 10 pivoted to an end-post 2. A tail-spindle 11 carries at its forward' end a clamp 12 and at the rear a split-nut 13 coacting with a fixed screw 15, and is rotated at the same speed as the spindle 5 by means of toothed gearing 17, countershaft 19 and gearing 18. In Fig. 1, two parallel support-wires are fed from reels 22 and pass into grooves 24 in a flat mandrel 25 which is held in the spindle 5 by means of a cap 26. The projecting ends of the support-wires are gripped in the clamp 12 and in operation the nut 13 is closed on the spindle 15, thus causing the tail-spindle to retreat and draw the supportwires, which rotate bodily with the mandrel, through the machine while the coil is wound on from a reel 33. The pitch of the screw 15 is the same as that of the coil to be wound. In order to notch the support-wires to receive the coils, they are carried during the rotation of the mandrel beneath a notching wheel 27 mounted in an adjustable yoke 28. After coiling, the notches are closed over by a disc 34 mounted on an arm 35 and held against an adjustable stop 36 by a spring 37. Some of the notches are left open at intervals to facilitate cutting the finished coils into separate valve-grids and for this purpose the closing disc may be lifted periodically by a cam 39 rotated through ratchet mechanism operated bv an eccentric 41 on the countershaft 19. When the tail-spindle reaches the limit of its travel, the machine is stopped automatically by the engagement of the nut 13 with a projection 16 on the clutch-operating lever 10 and a length of completed coil cut off by means of a shear 42 operated through a lever 43 from a pedal. In a modification, Figs. 6 and 7, a single supporting- wire 21 is fed through a channel 44 in the spindle 5 and along a groove in an eccentrically-mounted cylindrical mandrel 45 having a tapered end 46. A spring finger 48 assists in holding the support. wire in its groove and the coiling wire is fed from a reel 33 through a guide 50. Rotation of the mandrel carries the support wire alternately beneath the notching-wheel 27 and the closing- wheel 34 to secure the coiling wire in position. In a further modification, the notching operation may be performed by means of a reciprocating chisel and the closing operation by a reciprocating hammer. Specification 263,089 is referred to.

Abstract: 1,255,831. Filters. J. MULLER. 24 Jan., 1969 [5 Feb., 1968], No. 4258/69. Heading B1D. In the type of filter having circumferentiallydisposed filter elements 49 which are backwashed sequentially by an intermittently rotating suction duct 66, the incoming fluid is heated by means 61 to reduce its viscosity before it is filtered. As described, each filter element 49 comprises a stack of grooved strips 76 (Fig. 4), defining an edge filter, fluid flowing into it via apertures 77. Incoming fluid, such as oil, passes under baffle 75, through electric or steam heater 61 (80‹C); up into space 56; and into the elements 49 via holes 54. Water separates out and collects in space 74, to be drained periodically by a float-controlled valve. Filtrate rises and passes through heaters 62 (110‹C) and then a further, similar, array of filter elements 50, finally emerging at 72. Shaft 51 is rotated by an electromagnetic ratchet device 65 (see also Fig. 3, not shown), or by a device driven by the fluid itself, suction being applied at waste outlet 68. A spring-loaded piston device P compensates for the pressure fluctuations in the outlet chamber caused by the backwashing.
