Title: Method of printing films with sound and picture records and apparatus therefor
IPC: G03C5/14
Filed: 1929-09-04
Abstract: 319,660. Electrical Research Products, Inc., (Assignees of Coffman, J. W.). Sept. 25, 1928, [Convention date]. Combined sound and kinematograph records. -In printing a positive film from a single negative film which has both sound and picture records thereon, provision is made for filtering the printing ligh directed on to one or both of the records so as to obtain a differential overall contrast between the printed sound record and the printed picture record. This may be effected by incorporating a dye in the positive film emulsion and directing the light for printing the sound record through a filter of a complementary colour. To enhance the contrast in the picture record, the light for printing this may be directed through a filter of the same colour as the dye. Apparatus for printing comprises sprocket rolls for feeding the superposed films between a pad 7, Fig. 1, and a mask 6 adjustable vertically in relation to the printing light 5 to position any one of three apertures 8, 9. 10, Fig. 2, in the light path opposite to an aperture in a back plate 11. The aperture 9 covered by a suitable colour filter is positioned for printing the sound record alone, and the aperture 8, covered if desired by a suitable colour filter, is positioned when the picture record alone is to be printed. The aperture 10 is provided so that the apparatus can be used for printing ordinary full size picture records without a sound record thereon.

Abstract: 782,499. Heating charge; carburetters. WEAVER, W. A. Nov. 2, 1953 [Oct. 31, 1952], No. 27383/52. Class 7(3) The exhaust gases are allowed to pass around the exterior of an angled chamber forming part of the engines induction system the inlet and outlet limbs of such chamber merging from a circular section at their outer ends to a flattened section at their junction. Mixture from a carburetter 12 flows through an angled passage 11, 13 which takes the shape of a figure seven in side elevation (Fig. 3, not shown), and then passes to an inlet manifold or port 15 of the engine. As shown a jacket 16 surrounds the passage 11, 13 and exhaust gases from the engine enter this jacket from a pipe 20 leading from the exhaust manifold or ports. In order to control the heating of the mixture a thermostatic element 32 controls a lever 33, 35 which is connected by a link 36 to a by-pass valve 23 which can by-pass any proportion up to say 50 per cent of the exhaust gases to a pipe 31 leading to the silencer which latter is also connected to an outlet pipe 30. As shown the connection of the link 36 to the lever arm 35 is manually adjustable. It is stated that the connection may be adjusted under governor control. In a modification the. valve 23 may be manually adjusted and then fixed or alternatively the thermostat may be dispensed with and the by-pass valve controlled by a governor sensitive to engine speed. In another modification the valve 23 may be controlled by exhaust gas pressure which can move it in opposition to the force of a spring. The valve 23 may be acted on by a torsion spring 38 or by a weighted arm. The weight may be adjustable. A thermometer may be fitted to indicate the exhaust gas temperature. Two or more heating means may be provided and used singly or together. For a four cylinder engine two exhaust pipes may be provided each serving two cylinders and each containing a by-pass valve such as 23. One exhaust pipe would be permanently bypassed to the silencer when working in a temperate climate the valve the air being thermostatically operated to admit additional heating gases to the jacket 16 when working at sub-zero temperatures. The several means described for controlling the heating may be used singly or in combination. The fuel used may be tractor vaporizing oil, paraffin or other light fuel oil. The by-pass valve may be omitted or disconnected from the bell crank lever 33 the latter being connected by a link (indicated at 44). to the usual actuating arm 45 on the throttle valve spindle of the carburetter. The throttle arm 45 may be connected to a governor the by-pass valve having a lost motion connection to the governor control so that full throttle is permitted until a predetermined engine speed is reached after which the by-pass valve is automatically opened regardless of the position of the bell-crank lever 33.

Class 103(vi) A rail-vehicle undercarriage comprises a bolster 12 provided with wear plates 56 to engage the spring-urged wedge members 16 which co-operate with the inclined walls 44 of the side frame to damp vertical oscillation of the bolster. The wedge member is provided with upstanding ears 66 which will project into the space 26 and thereby prevent the bolster 12 from being inserted in the side frame if the wedge members 16 are assembled with the curved face 58 engaging the bolster 12 instead of the face 44 of the side frame. A dowel 64 provided in the centre of the spring seat 62 ensures that the upper end of the spring 18 is positioned before the lower end during assembly. The wedge elements 100, Figs. 6 and 7, may be associated with secondary wedge elements 102 which bear against the side wall of the wedge pocket to preclude swivelling of the wedge during angling of the bolster and side frame in service. Thus during angling the wedge elements must move upwardly and compress the springs 108 and thus provide a restoring force to return the bolster into squared relation to the side frame. Specification 655,180 is referred to.

Title: Improvements in or relating to the purification of sodium
Inventor: ALTIMIER DAVID FREDERICK
IPC: C22B26/10
Filed: 1958-09-01
Abstract: Sodium is treated to remove any residual calcium content by intimately mixing a gas mixture with molten sodium at a temperature below 300 DEG C., the gas mixture containing at least 98% by volume of an inert gas such as nitrogen and 2% or less by volume of oxygen. The gas mixture, the volume of which is preferably at least 20 times that of the sodium treated, may be introduced into the melt by bubbling or by means of a turbomixer. The gas may be continuously recirculated and replenished with an oxygen-containing gas such as air to maintain the concentration of oxygen.  Calcium is then separated by allowing the melt to settle or by filtration.  The process is effective in removing calcium from sodium containing up to 1,000 parts per million of calcium.
