Title: Improvements relating to dial reading measuring instruments
IPC: G01D11/28
Filed: 1928-01-06
Abstract: 304,016. Evershed & Vignoles, Ltd., and Midworth, C. Jan. 6, 1928. Dials and scales, illuminating.- The dials of instruments, such as ohmmeters, incorporating a hand-actuated electric generator are illuminated by one or more low-pressure gas discharge tubes supplied with current from the generator. In the construction shown in Fig. 1 a neon tube a is mounted behind the bezel b of the cover glass c of the instrument dial d, the tube a is of elliptical cross-section with its major axis parallel to the plane of the scale d. The negative electrode from which the bulk of the light is emitted is a wire e placed along the edge of the tube remote from the scale d, the positive electrode consisting of a wire f entering the tube at the opposite end and arranged parallel to the wire e and spaced slightly above and to the front thereof so as not to cut off much of the light. Any deposition due to electron or ionic bombardment is thus kept clear of the wall of the tube adjacent to the scale. Alternatively a long tube may be employed in which the majority of the light is emitted from the positive gas column, and the tube may be curved to conform to the scale. One or more short neon tubes having considerable negative glow may be distributed around the dial and connected in parallel across the generator. A gravity switch may be employed so that the neon tube is illuminated only if the instrument is tilted.

Title: A method and apparatus for coating articles
IPC: B05D1/06
Filed: 1962-01-05
Abstract: <PICT:0976327/C1/1> <PICT:0976327/C1/2> Articles, e.g. pipes, angle irons, structural members and flat articles, are subjected to a centripetal jet of coating material while passing through a port of the coating chamber, a continuous flow of air into the chamber being maintained during the coating, e.g. by reducing the pressure.  The article may be passed, while rotating, through the chamber or dipped into the chamber.  The article may be precleaned, preheated, heated in the coating chamber and postheated (e.g. heating by induction). The coating material may be thermo-adhesive, e.g. epoxy resin, phenol-formaldehyde resin, polyethylene or enamel, and woodflour, inorganic gait or talc may be applied with the thermo-adhesive material or applied subsequently to it.  Other components which may be present in the coating material include isophthalyl dihydrazide, dicyandiamide, tris - (dimethyl-aminoethyl) phenol, alkyl ammonium bentonite, mica, and chrome oxide.  In the case of pipes strip material, e.g. paper, is wound round the coated pipes. Faults in the coating may be detected by the occurrence of an arc discharge when the earthed coated article is passed through a circular conducting member to which a voltage is applied, and any blemishes in the coating may be removed by further spraying.  As shown, coupled pipe lengths 10 and 11 are moved through cleaner B, heater C, coater D and cooler E.  Chamber 19 of coater D is supplied with coating material by conduits 20 via manifolds 13 and 14 and annular orifices defined by ring members 15 and 16 and 17 and 18.  Pump G withdraws air and excess coating material from chamber 19 via conduits 21 to conduit 22 from where excess coating material is returned with fresh material from conduit 23, to conduit 20 via conduit 24 by blower H.ALSO:A coating composition comprises a mixture of two epoxy resins, isophthalyl dihydroxide, dicyandiamide, tris (dimethylaminomethyl) phenol, alkyl ammonium bentonite, mica, and chrome oxide.

Title: Improvements in and relating to Colour Kinematography.
Inventor: DONISTHORPE FRANK WORDSWORTH
Filed: 1916-01-20
Abstract: 102,280. Donisthorpe, F. W. Jan. 20, 1916 Kinematograph apparatus; three-colour and like systems; optical-projection apparatus. - Kinematograph films bearing pairs of colour record images, the images of each pair being arranged side by side with their horizontal lines parallel to the length of the film, are projected by a standard projector provided with an optical system which rotates the images through a right-angle about the axis of projection and combines them so as to produce an erect picture on the screen. The images each occupy half the area of each image on an ordinary film, and the projected picture thus has approximately the usual ratio between its vertical and horizontal dimensions. The images may be rotated by means of a single prism having a reflecting surface parallel to the axis of projection and inclined at an angle of 45 degrees by three right-angled prisms or by an equivalent arrangement of mirrors. The optical system may be carried by a tube 3, which is shown in horizontal section in Fig. 4, and which replaces the usual lens tube. The tube 3 contains an adjustable inner tube 4, which carries a circular slide 5 containing a lens 6 and colour filters 7, 8, and also a divided lens, the parts 9, 10 of which are placed with their curved edges adjacent, as shown, or with the straight edge of one of them adjacent to the curved edge of the other, and are relatively adjustable in vertical and horizontal directions to obtain accurate registration of the projected images. The projection of both images through each lens part 9, 10 is prevented uy means of a vertical partition having a fixed part 30 and a part 31 which is pressed bv springs against the gate 2, the partition being pivoted at 34 and being adjustable by means of a wedge-shaped member 35, which bears on a projection 37 and enables it to be accurately centred with respect to the film. The reflecting-prism 18, Fig. 8, may be carried by an arc-shaped member 22 adjustable axially on the end of the tube 4, being mounted in a support 19 hinged to the member 22 at 23 so as to be adjustable, and being secured in adjusted position by nuts which clamp pivoted links 26 to arms 28 extending from the support 19. The circular slide 5 may be replaced by a rectangular slide containing different pairs of complementary coloured filters, any of which may be brought in front of the lens. According to the Provisional Specification, the partition may pass through the lens to the shutter.
