[Class 40 (iii)] An optical image, projected on an apertured disc 8 producing interlaced scanning, is given a trapezoidal distortion which corresponds with the trapezoidal scanning area of the disc, as described in Specification 464,831. The size of the image projected on the double-spiralled disc is finely adjusted by displacing the film 13 in the direction of the incident light by a slide 18 simultaneously with the projecting lens 19. The image is raised or lowered by adjusting the position of the film by a spindle 21. The inclinations of the axis of the light to the disc and to the film are adjusted about a journal 17. The phase of the film is adjusted by an eccentric roller 24. An edge of the film is shaded and is filled in by a very white line, for producing synchronizing signals, which is projected from a gap intensely illuminated by a condenser from the common light source, Figs. 3 and 4 (not shown). The position of the white line is adjusted by rotating a piano-parallel piece of glass. Specification 465,185 also is referred to.

[Class 135] A multiple-way valve device has a series of independently actuated diaphragm valves housed in a single casing and to facilitate the passages being provided with a corrosion resisting lining of rubber, lead or glass the casing is divided along a plane parallel with that containing the axes of the inlet and outlet openings. In the form shown in the Figure, five valves are employed and four of the flanged inlet or outlet connections 5 are formed partly in the lower casing section 2 and partly in the upper casing section- 1: A fifth flanged connection 15 is formed on a separate, piece bolted to the lower section and formed with a passage adapted to connect with an aperture in the section 2 leading to an inner chamber. Various passages are formed within the casing by dividing walls partly in the top and bottom sections. Barriers with concave tops intersect the passages opposite the openings in the top sections which are fitted with diaphragms and diaphragm actuating means. In a modification adapted to be made of welded metal the various passages and inlet and outlet connections are formed wholly in the upper section which is closed below by a flat plate.

Abstract: 794,985. Electric tests. ROLLS-ROYCE, Ltd. Dec. 7, 1955 [Dec. 7, 1954], No. 35486/54. Class 37. Inspection apparatus for engineering parts indicates the degree of correspondence of the test-piece with a master part in contact with a probe by measuring the extent of the spark gap between said test-piece and a follower. As shown (Fig. 1) movement of a transverse beam 15 is effected in a vertical plane within slide 14, cable 17 passing over pulley 16 and being attached to a counterweight within pillar 11, and in a horizontal plane transversely and lengthwise of a base plate 10 to which it remains parallel. Probe 18, adjustable by micrometer screw 18A, contacts the master part 20 while the follower 19 passes over the test piece 21, deviation plus or minus from a pre-set nominal gap length giving indication of undersize or oversize of the test piece 21. Spherical formation of probe and follower ends facilitates the inspection of multi-planar test pieces. In the circuit (Fig. 3) the output of step-up transformer A is applied through resistance RG to the gap between follower 19 and test piece 21. Variations in the gap length, which vary the grid potential and thus the anode current of triode B, are indicated on meter M. Selector switch S controlling transformer tapping T1- T3 is ganged with selector switch V controlling resistors RK1-RK3 to provide range multiplication. Alternative or additional visual or aural indication when the deviation exceeds a prescribed limit is mentioned.

Title: Improvements in fused salt baths for use in the electrodeposition of refractory metals

Abstract: 782,371. Electrolytic production of refractory metals; fused halide salt electrolytes. HORIZONS TITANIUM CORPORATION. Dec. 10, 1954 [Dec. 14, 1953], No. 35818/54. Class 41. A fused salt bath for use in obtaining electrolytically one of the refractory metals titanium, zirconium, hafnium, niobium, vanadium, and tantalum is produced by fusing at least one halide salt of an alkali or alkaline earth metal in admixture with a carbide of the refractory metal, a carbide-monoxide mutual solid solution of the refractory metal, or the refractory metal in impure form, and introducing into the resultant mass chlorine, phosgene, or a mixture of carbon monoxide and chlorine until the refractory metal content has been converted to lower valency chlorides in solution in the fused salt. The process may be carried out batchwise in an apparatus comprising three vertically superimposed graphite crucibles disposed in a graphite container heated by the passage of current therethrough and surrounded by a metal shell. Argon is passed continuously through the container and after the removal of air a fused melt of sodium chloride, potassium fluotitanate, and titanium carbide or carbidemonoxide or impure metal is formed in the top crucible. Chlorine is then fed into the melt and thereafter the titanium chloride-containing melt is run off through a graphite needle valve in the bottom of the crucible into the middle crucible which incorporates a petroleum coke filter in its bottom. The filtered melt is received in the third crucible where it is electrolysed using a carbon anode to yield a cathodic deposit of titanium and anodic evolution of oxides of carbon (formed from oxygen impurities in the bath) and chlorine. A similar process for niobium is described. Alternatively the evolved chlorine may be used to chlorinate the refractory metal starting material and together with the spent salt bath may be used to give a cyclic process. Specifications 778,218 and 788,295 are referred to.
