The transverse movement may be effected by three different methods, viz. (a) by dividing the transverse section through the deposited layer into sectors A to E (Figs. 1, 2, not shown) and using to produce the transverse movement a variable speed motor whose speed is kept constant within each sector, being changed only when passing from one sector to another, (b) by a variable-speed motor whose speed is controlled in continuously-variable manner by a variable-height cam (Figs. 31, 36, not shown), (c) by a constant-speed motor in steps of varying time duration (see Fig. 4, not shown). The transverse movement taking place for only a variable, controlled fraction of a carcass revolution.

A high pressure mercury vapour electric discharge lamp of the kind having a quartz discharge envelope mounted within a glass outer jacket, wherein W/1, where W is the wattage and 1 the arc length, lies between 40 and 100 W. per cm., and the discharge envelope is of such shape that the external wall temperature lies everywhere between 580C. and 650C.; and the metal filling inside the lamp includes a quantity of zinc in such proportion that when the lamp is operating at W watts from an alternating supply the voltage drop per cm. of arc length is between 10 and 35, and the number of burners emitted at wavelengths between 4600 and 5100 is not less than 2% of the total light output of the lamp ; and the discharge envelope is surrounded by a screen coated with a red fluorescing phosphor of such thickness that the number of lumens emitted at wavelengths between 6100 and 7200 is not less than 5% of the total lumen output of the lamp ; the proportion of zinc filling, e.g. the lamp contains 80 mgm. of mercury and 40 mgm. of zinc and the thickness of the phosphor layer being, however, so small that the initial luminous efficiency of the lamp is not less than 40 lumens per watt. The outer glass jacket may be ovoidal and the inner quartz envelope 94 mms. long, containing directly heated electrodes formed from a tungsten rod containing a slot in its side, the slot contains an electron-emissive pellet which is held in place by a tungsten helix the electrodes are spaced 800 mms. apart and an auxiliary electrode is set in the wall near one end of the tube. The innermost parts of the seals of the tube are coated with platinum to reduce ' cold-spot ' effects and the tube is filling with argon at 20 mm. to act as a starting gas and the space between the envelopes is evacuated. The wall temperature is measured by means of a thermo-couple.

Title: Vitreous enamels
IPC: C03C3/072
Filed: 1965-04-27
Abstract: A vitreous enamel is in the form of composite particles composed of pigment dispersed in glass frit.  The particle diameter/wt. per cent distribution is as follows: up to 1 m , \sO 1%; up to 2 m , <8%; 3-10 m , 10-80%; 5-20 m , \sP 55%; greater than 30 m , \sO 10%; greater than 35m , \sO 5%; less than 45 m , 100%.  The pigment, usually of particle size less than 5 m  is mixed with frit previously ground to pass a 200 mesh screen (U.S.S. sieve).  The pigment may constitute, e.g. 8-12% wt. of the mixture. The mixture is heated e.g. in a kaolin-lined clay vessel at e.g. 550-750 DEG  C.  After water- or airquenching, the frit-pigment cake is crushed and milled to pass a 200 mesh screen. It is then size classified, e.g. by sedimentation from aqueous slurry or by centrifugal classification in a counter-current air-stream.  The resultant frit-pigment particles may then be applied to surfaces by electrostatic attraction, a stencil screen being placed in front of the surface, the surface being the hot article to be treated or an off-set plate.

Abstract: 853,608. Lathe details. ERNAULT-BATIGNOLLES, H. May 26, 1959 [May 30, 1958], No. 17955/59. Class 83 (3). Mechanism for gauging the position of a slide, fed by a screw, such as a lathe tool-slide, comprises two coaxial discs, one rotating with the screw and the other independent of the screw and adjustable by worm-gearing, the latter disc having a radial groove and the former having opposite thereto a spiral groove and a ball-member being engaged by both grooves. The transverse slide 5, Fig. 1, carried by a saddle 4, is moved by a hand wheel 7 turning a screw 6a engaging a nut 5a secured to the slide 5. The front end 6, Fig. 2, of the screw is keyed to a member 9 having a spiral groove 14, Fig. 5, in its end face. A member 8, freely rotatable on a sleeve 10, Fig. 2, also keyed to the screw 6, 6a, has a single radial groove 13 facing the spiral groove in the member 9. A ball 15 is arranged between the grooves. The member 8 is integral with a worm-wheel portion which is engaged by a worm 19. The latter is rotatably adjustable by a graduated knob 23, Fig. 3, in a swing-bracket 26 pivoted at 27 to the transverse slide and moved by an eccentric pin and groove 28, 31, respectively. An extension 32 of the bracket 26 has a claw 33 which engages a notched part 35 of a disc secured to the lever 34 for operating an automatic crossfeed. The latter is thus prevented from operation when the worm 19 is engaged for hand-adjustment and gauging.
