Title: Improvements in or relating to the manufacture of refractory metals
IPC: C22B34/32
Filed: 1955-01-20
Abstract: Refractory metals having a melting point higher than 1830 DEG F., e.g. Cr, Ti and Zr, are manufactured by interacting CaC, and a non-volatile oxide, sulphide, or oxidized or sulphurized ore of the metal in the presence of a flux and at a temperature substantially lower than the melting point of the metal, and preferably at a temperature not substantially higher than the melting point of the flux.  The latter may be boric anhydride, alkali metal chloride calcium chloride, simple or compound fluorides, borates or fluoborates.  The reagents may be intimately mixed, but preferably are disposed in successive layers, the flux being uppermost, and preferably with an excess of CaC2. The reaction mass may be diluted with a substance inert under the operating conditions, e.g. CaO.  The reaction may be carried out in a refractory steel retort of tapered shape with removable bottom and cover members, and four suitable retorts are described and illustrated in the Specification.  When the reaction is complete lime and flux are removed by washing in water which may be acidified, the carbon is removed by froth flotation, the silica is removed by using a liquid of density between that of the metal and silica, and the last impurities are removed by washing with HNO3, thereby leaving a spongy metal powder.  Iron metal by magnetic separation followed by treatment with an acid which does not attack the refractory metal.

Title: Improvements in or relating to photographic shutters
IPC: G03B9/08
Filed: 1940-02-09
Abstract: 534,370. Photographic shutters. KODAK, Ltd. Feb. 9, 1940, No. 2509. Convention date, Feb. 11, 1939. [Class 98 (i)] A shutter of the type comprising a pivoted aperture blade 15 to which a cover blind 10 movable by the shutter trigger 8 is latched so as to cover the aperture during movement of the blade in one direction to tension the spring, the latch being released at the end of the movement to permit the blade to move alone in the reverse direction to make the exposure, is provided with a retarding device comprising a gear segment 21 and weighted pinion 22 engaging it, one being carried by the shutter blade and the other by the casing. This causes the shutter to operate at a slower speed, and avoids change of speed due to gravity effects when the camera is held in different positions. In the form illustrated, Fig. 1, showing the parts before an exposure, and Fig. 3 after exposure but before release of the trigger 8, the cover blind 10 is secured to the shaft 9 of the trigger, and is provided with a latch element 11 which is engaged by the end of a spring arm 12, Fig. 7, extending from one edge of the shutter blade. On depression of the trigger, the blind 10 carries the blade with it until the end of the arm 12 rides up on a stud 20, the blade being thus unlatched and returning under spring action to make the exposure. The retarding means comprise a rack 21 formed on the edge of the block and engaging a pinion 22 to which a small flywheel 24 is attached. " Bulb " exposures are obtained by moving a lever 25 to cause the upturned end 28 of an arm 27 to arrest the blade in the open position. In a modification, the pinion is mounted on the blade, and engages a fixed rack segment. In another form, the pinion is carried on a pivoted arm so that it may be moved out of engagement, with the rack on the blade to give a shorter exposure. A modification providing a speeded shutter is shown in Fig. 12, a spiral spring 61 being secured at its inner end to the shaft 52 of the pinion 51 and at its outer end to a disc 56 which can be rotatably adjusted to vary the spring tension by an external knob 57.
