Title: Improvements in or relating to the manufacture of light-transmissive shaped bodies of refractory oxide material
Inventor: RIGDEN SYDNEY ALFRED RICHARD
IPC: C03B19/00
Filed: 1964-02-20
Abstract: Envelopes of light-transmissive refractory oxide material (Al2O3, SiO2, ZrO2, TiO2) are produced by contacting the surface of a hollow former of the desired shape with a gaseous mixture consisting of hydrogen and carbon dioxide with the vapour of a halide of Al, Si, Zr or Ti, and heating the former to such a temperature that the gaseous mixture reacts in the vicinity of the surface to deposit an adherent layer of the oxide(s) on the former and continuing until sufficiently thick to produce a coherent body on removal of the former.  The former may be a thin-walled tube of ductile metal, e.g. copper or nickel, the interior surface thereof having the shape of the exterior of the desired envelope, the gaseous mixture flowing continuously through it while maintained at the required temperature.  The former and layer are preferably allowed to cool before separation, e.g. by dissolving the metal in a solvent which does not attack the oxide layer. The carbon dioxide and the hydrogen may be in equal proportions or there may be excess hydrogen (preferably such that the ratio CO2:H2 is between 1 : 1 and 1 : 2), and may be passed over the halide, which may be in solid or liquid state, so as to form the required gaseous mixture, which is heated to ensure that the halide remains in the gaseous state and is then passed continuously in contact with the former which is maintained at 700-1000 DEG  C.  The rate of deposition may be between 4 x 10-7 and 9 x 10-6 ins./min. The light-transmissive envelope may be used in an electrical device, e.g. a discharge lamp.

Title: Improvements in or relating to the production of cinematograph colour films
IPC: G03C7/18
Filed: 1943-05-11
Abstract: 565,385. Colour kinematography. TECHNICOLOR MOTION PICTURE CORPORATION. May 11, 1943, No. 7495. Convention date, Nov. 26, 1942. Drawings to Specification. [Class 98 (ii)] In the production of kinematograph colour films wherein colour correction for undesired light absorption by the subtractive dyes used is made by printing a colour-component film while it is in register with a masking film, successive frames over a short length at one end of the masking film are gradually blocked out before the printing step, so that this film not only effects colour correction, but also produces a fade at one end of the picture sequence. Where two or more picture sequences follow one another on the same film, the masking films used are blocked out at each end by gradually increasing the overall density of the frames towards the end, and the sequences are printed with an overlap equal to the blocked-out length so as to produce a dissolve. Instead of gradually changing the density of the frames, gradually changing areas of the frames may be opaqued out so as to produce a wipe. The blocking-out may be effected by dyeing, e.g. by imbibition printing from a relief matrix which has the same thickness of dye-absorptive coating throughout each frame, the thickness increasing or decreasing, however, from frame to frame. The masking film and the colourcomponent film with which it is printed in register are of complementary character (one positive and the other negative), and the mask is a weak record of the component primary colour which is undesirably absorbed by the subtractive dye used in the print of the colourcomponent film; thus, a blue colour-component negative record may be registered with a weak green colour-component positive masking record to correct for undesired green absorption of the yellow subtractive dye used for the blue-aspect print, or a green colour-component negative record may be registered with a weak red colour-component positive masking record to correct for undesired red absorption of the magenta subtractive dye used for the green-aspect print. The masking record may be printed from a colour-separation record if available, or may be made in the camera simultaneously with the exposure of the colour component records as described in Specification 565,384.

Void [Abridged as open to inspection under Sect. 91 of the Acts, March 17, 1932]. [Class 61 (iii).] In an adjustable spanner in which the movable jaw moves transversely to the length of the handle, the operating means comprises a slide mounted in the handle to move longitudinally of the spanner, and carrying a spigot which engages a groove in the movable jaw. The locking means for the slide comprises a spring-expanded catch engaging teeth on the guides. The body of the spanner, Figs. 1 and 3, has a head 1, fixed jaw 2 and handle 7. A groove 5 in the head receives the body 11 of the movable jaw, 2a, Fig. 5, a collar 12 on the jaw being guided in the groove 5a. A spring- pressed plunger 14 prevents play, and the body 11 has an inclined groove 13, which receives a cylindrical spigot 13a carried by the slide 16, Fig. 8. The slide is hollow and is mounted in dovetail fashion on the edges 8 of the opening 7a in the body of the spanner ; holes 10 receive a pin to limit the movement of the slide after assembly. A spindle 17 mounted in the slide carries the expanding catch 19, 20, Fig. 10, formed of two pivoted parts, a spring 22 normally keeping the lower ends apart, so that they project from the slide and engage teeth 9 formed on the guiding ribs 8. The upper ends 21b of the catch lie against either side of a small shaft 21-21a slidably mounted in the member 16. When the shaft is centered the narrow part of this shaft lies between the ends 21b but on displacing it to one side the ends 21b are forced apart, so that the claws 19, 20 are disengaged from the teeth 9. The slide can then be moved downwards to increase the opening of the jaws. The jaws may be closed without operation of the shaft 21-21a.
