Title: Improvements in or relating to resilient suspensions for vehicle axle-boxes
Inventor: HIRST ARCHIE JOHN
IPC: B60G11/22
Filed: 1952-09-03
Abstract: 720,365. Axle-bearing guiding arrangements. METALASTIK, Ltd. Sept. 3, 1952 [June 20, 1951], No. 14690/51. Class 103 (6). An axle-box suspension mounting comprises resilient elements 15 mounted fore and aft of the axle box 12 and supporting it from a chassis frame 10 or other body-supporting structure of the vehicle, each element 15 including chevronshaped rubber blocks 16 surface bonded to correspondingly shaped leaves 17a, 17b, 17c. The arrangement is such that transverse loads are resisted by the rubber blocks 16 mainly in compression whereas substantially vertical loads will be resisted by the rubber blocks mainly in shear. In the arrangement shown in Figs. 1, 2 and 3, each end leaf 17a is secured to a bogie sole plate 10 by means of a suitably shaped bracket 18. Each inner leaf 17c is secured by bolts 26 to a member 19. The members 19 are joined at their upper ends by a yoke 29 having a centrally disposed boss 31 the bore 32 of which is screw threaded to receive a bolt 33 which bears against a surface 34 on the top of the axle box 12. Vertical flanges 14 on the sides of the axle box engage grooves formed in the members 19 so that adjustment of the height of the axle box in relation to the resilient elements 15 may be effected by adjustment of the bolt 33. The aperture 11 in the sole plate 10 is bridged by a rigid tie rod 38. The resilient mounting elements 15 are so constructed that the rubber blocks 16 are preloaded in compression and shear when under tare load. In a modification, each of the mountings arranged fore and aft of an axie box 12, Figs. 6 and 7, comprises a set of two opposed but coupled chevron-shaped resilient mounting elements 15. A pair of triangular-shaped members 40, Fig. 9, fills the space between each pair of elements 15. The outermost and innermost rubber blocks 16 are bonded to surfaces 47 of blocks 48, Fig. 8. The innermost blocks 48 directly engage the axle box 12 and are located transversely by spaced flanges 54 and adjustable vertically by means of bolts 57 located in eyes 56 on the axle-box 12. The outermost blocks 52 engage brackets 51 bolted to the sole plate 10. The fore and aft resilient mountings are bridged by a tie rod 42 having enlarged apertured ends 43, through which pass bolts 44. The latter also pass through holes 41 in the blocks 40, and through straps 45, the rigid assembly being completed by nuts 46. In any suspension in accordance with the invention a rubber pad which is remote from the axle box may be made of less height and of greater width than the rubber pads nearer the axle box and offset upwardly in relation to these pads in order to increase resistance to canting of the metal leaves. Specification 648,516 is referred to in the Provisional Specification.

Title: Improvements in or relating to processes for the production of extremely pure substances
IPC: C22C1/00
Filed: 1955-05-23
Abstract: <PICT:0812818/III/1> In the production of extremely pure substances by deposition from a gas by thermo - chemical reaction, the deposited substance is absorbed in a depending liquid drop 4 of the same substance adhering to a solid rod 3 of the substance, liquid being simultaneously crystallized on to the rod.  As crystallization proceeds the rod is withdrawn from the reaction chamber.  The drop may initially be supported by a carrier of different material, e.g. carbon, graphite, quartz or tungsten, and the liquid may initially contain a seed crystal to determine the direction of crystallization. The liquid may be prevented from dripping by a blast of air or other gas or an electromagnetic field.  The drop may alternatively be supported between two rods (Fig. 2, not shown).  The two rods may be moved axially in opposite directions, or in the same direction, in the latter case producing a thickened rod.  The reaction may be carried out directly on the surface of the hot liquid, a gaseous reactant being directed on to the drop from a pipe 2.  The liquid may be heated by a high-frequency coil 5 after preheating by radiation or by atom, electron or ion bombardment, or (in the case of two rods) by passing a current through the rods and liquid drop.  The reaction may be carried out some distance from the liquid and the deposited substance carried to the liquid by means of a temperature or pressure drop, a current of inert gas, e.g. a rare gas, or an electric discharge.  Heat for the reaction may be provided by an electric discharge using alternating or direct current.  The gas may be formed by vaporization of a solid, in which case direct current may be used, the solid being placed on the anode.  Oscillations may be applied at the phase boundary between gas and liquid.  When the drop of liquid is supported by an electromagnetic field, the oscillations may be produced by superimposing a low-frequency alternating electromagnetic field of small amplitude on the supporting field.  Cooling means may be provided to solidify the liquid at the liquid-solid junction more rapidly.  The rod or rods may be rotated, and special means, e.g. a rotating magnetic field, may be employed for the rotation of the liquid zone.  Additives i.e. donors, acceptors, traps, recombination centres, &c., may be incorporated in the liquid zone.  A current of steam, carbon monoxide or carbon dioxide at low pressure may be passed through the apparatus.  The rod produced may be additionally purified by zone melting.  Silicon may be deposited from silicon tetra-, hexa-, or octa-chloride, or silicochloroform.  Hydrogen may also be present.  Boron nitride may be obtained from B3N3H6 (triboron triamine), aluminium nitride from AlH3 NH3, and indium phosphide from InI3PH3.  Other starting materials specified are: AlH3.PH3, AlH3.AsH3, GaH3.NH3, GaH3.PH3, InH3.NH3, AlCl3.NH3, AlCl3.PH3, AlCl3.AsH3.

Title: Improved means for measuring the deflection of railway sleepers under load to determine the deficiency of ballast
IPC: G01B5/00
Filed: 1951-06-22
Abstract: 681,075. Deflection gauges. TUSTAIN, E. H. June 22, 1951, No. 14909/51. Class 106 (ii). [Also in Group XXX] A device for measuring the deflection of a railway sleeper when rolling stock is passing over the rails comprises a base 1 supporting a double-armed lever 7 having one arm 7b adapted to extend beneath a rail 17 and the other 7a constituting a pointer extending over a graduated scale 4 supported from the base 1 and a frictionally-mounted pointer 9 movable by said first pointer 7a and means 8 for returning the pointer 7a to initial position. The lever 7, pointer 9 and plate 3 with scale 4 marked thereon are all pivoted on a spindle 5 mounted in a struck-up portion 1a of the metal base 1. The plate 3 is clamped against a shoulder of the spindle by a nut 6, the lever 7 is free on a reduced portion of the spindle while the pointer 9 is engaged between two washers 10 and frictionally clamped by a spring 11 compressed by lock-nuts 12 prevented from removal by a pin 13. A spring 8 encircles the spindle 5 and engages the plate 3 and arm 7b urging the latter into contact with the rail 17 so that, with the plate 3 adjusted so that the pointer 7a reads zero and the pointer 9 set in contact with a projection 14 on the pointer 7a, the passage of rolling stock over the rail depresses the arm 7b causing the pointer 7a to push the pointer 9 over the scale 4 where it is frictionally held in maximum position while the pointer 7a returns to initial position, the distance therebetween indicating the deflection of the rail. Straps 15 guide the pointers to prevent damage. For the purpose of adjusting the relative position between the arm 7b and rail 17 and pointer 7a and scale 4, the spindle 5 may be mounted in a slot and its height adjusted after slackening the nut 6.

Title: Improvements in or relating to matched terminations for wave guides and coaxial lines
Inventor: KHOURY KHALIL IBRAHIM
IPC: H01P1/26
Filed: 1952-06-16
Abstract: 732,683. Matched terminations for waveguides &c. DECCA RECORD CO., Ltd. June 15, 1953 [June 16, 1952], No. 15166/52. Class 40 (8). A matched termination for a wave-guide or coaxial line comprises two or more resistive elements 12, 13 spaced apart approximately #/4 in the guide or line, and a short-circuit 11 beyond the elements 12, 13. The elements may comprise strips of, e.g., graphite on a dielectric base or evaporated nickel-chromium alloy films on thin glass vanes. The strips may be slid into the guide through slots preferably in its narrow walls so that the amount of the coated material in the guide may be adjusted. This construction overcomes the difficulty of producing strips of known and constant resistivity. Due to the gaps between the strips and the broad walls of the guide and the effect of the dielectric base of the strips a capacitive effect is set up which is compensated for by slightly reducing the spacings l 1  and l 2  from #/4 to e.g. 0.9 #/4. An expression is given for calculating this distance. Expressions are given for calculating the magnitudes y 1 <SP>1</SP>, y 2 <SP>1</SP> of the shunt conductances of the elements 12, 13. y 1 <SP>1</SP>=¢ and y 2 <SP>1</SP>=2 for minimum variation of the resistive component, and y 1 <SP>1</SP>=0.293 and y 2 <SP>1</SP>=1.414 for minimum variation of the reactive component. As the magnitude of the reactive variations are greater than the resistive variations, y 2 <SP>1</SP> and y 1 <SP>1</SP> are usually given values nearer 1.414 and 0.293. For a coaxial line, the elements are connected between the inner and outer conductors.
