Title: A liquid-insulated electrical device
IPC: H01F27/33
Filed: 1962-09-26
Abstract: 1,020,431. Transformers. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Sept. 26, 1962 [Sept. 28, 1961; Oct. 27, 1961], No. 36538/62. Heading H1T. The oscillations produced in the insulating liquid of a liquid-insulated electrical device such as a transformer by magnetostriction are damped by regions 2, 3, 4, 5 of the tank wall having a greater degree of resilience than the remainder of the walls to concentrate the oscillations at these regions and by covering the regions at a certain distance from the tank wall by plates 7 of a material having a high sound damping capacity. Plates 7 are secured by supports 6 which carry cross members 8 through which pass holding means such as bolts 9 welded to the resilient portions 2, 3, 4, 5 to limit the amount they bend inwards during evacuation of the tank. Springs 11 are provided between cross members 8 and the regions 2, 3, 4, 5. There may be several plates 7, or several layers of filling, which have maximum sound damping effects at different temperatures, e.g. 20‹ C. and 40‹ C.

Title: Improved method for recovering alumina from aluminate liquor
Inventor: FUDERER ANDRIJA
IPC: C01F7/14
Filed: 1965-08-25
Abstract: <PICT:1123184/C1/1> A method of recovering alumina from aluminate liquor, comprises passing aluminate liquor down a column, passing a vapour mixture containing steam and methanol and/or ethanol through said column in countercurrent to the aluminate liquor, whereby alumina hydrate is precipitated and separating solid hydrate from the methanol and/or ethanolcontaining liquor thus formed.  In a preferred embodiment the methanol and/or ethanol is driven off from the methanol and/or ethanolcontaining liquor in a distilling column, at least part of the vapour from the first column being introduced into the lower part of the distilling column and at least part of the vapour from the distilling column being introduced into the lower part of said first column.  In the drawing, liquor 10 which has been separated from red mud is introduced into the top of column 3 and flows downwards, its methanol content increasing and its water content becoming less.  Liquid methanol 15 containing about 20 mol% water is added to the emerging liquor 14 which flows into the precipitation agitators 9.  When the hydrate has been stirred out and separated from the liquor, the liquor 11 is pumped into column 2 in which it loses the main proportion of its methanol content. The remaining methanol is driven off in column 4 and the liquor 12 which leaves column 4 contains only traces of methanol.  The liquor 12 from which methanol has been expelled is concentrated by evaporating a portion of its water content.  The concentration of the liquor may be carried out in a multi-stage evaporator, the first stage of which is heated with steam. Vapour 16 from column 2 may be condensed in a water-cooled condenser and part may be used to heat evaporator 8 which operates at less than atmospheric pressure and is used for concentrating liquor 12. The major part of the vapour 16 is taken into column 1.  The vapour 17 leaving column 1 may be introduced into column 2, the remainder into column 3 from which vapour 19 with a very small methanol content can be withdrawn.  Vapour 19 is taken into the bottom part of column 4.

Title: Improvements in and relating to a rail vehicle braking system
Inventor: SHATTOCK CHARLES FREDERICK BAY
IPC: B60T8/18
Filed: 1960-10-25
Abstract: 927,001. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. Aug. 24, 1961 [Oct. 25, 1960], No. 36622/60. Class 103 (1). In a compressed air braking system for rail vehicles the brake cylinder pressure is varied in response to changes in load carried by the vehicle and means 38 is provided for preventing the final setting and locking of the loadcontrol means 33 until the vehicle is in motion. In the embodiment illustrated in Fig. 1, the vehicle is empty and shown in its stationary position. Rollers 15 and 19 engage unsprung portions of the bogies 16 and 20 respectively and air pressure from a main reservoir pipe 39 acts against, and moves a piston 23 in a brakesetting mechanism 21 to the left, compressing the spring 25 and so forcing the rollers 15 and 19 through their respective linkages, downwardly into engagement with their respective bogies. This movement urges the piston-rod 24 into engagement with a piston-rod 29 and moves a centrally mounted piston 28 to the left against its spring 34, carrying with it the roller 31, which forms a movable fulcrum for the weigh beam 32 of the variable load-control valve 33 to vary the brake cylinder pressure according to the position of the roller 31 relative to the weight beam 32. When the vehicle moves and attains the speed of more than two or three miles an hour the standstill detector 38 cuts off the air from pipe 40 and exhausts it through pipe 41. This allows the spring 37 to move the piston 36 and pawl 35 upwardly to engage the ratchet teeth 30 on piston-rod 29 and so lock the piston-rod 29 in its extreme leftward position. Air escapes at a slower rate from behind the setting mechanism 23 due to the choke 42 and the piston towards the right under the influence of its spring 25. This causes the rollers 15 and 19 to move upwardly out of engagement with their respective bogies so that wear and vibration, due to movement of the bogies when running, do not have an adverse effect on the mechanism. If the vehicle is loaded during the period when it is stationary, the downward movement of the under frame 10 relative to the bogies 16 and 20, causes the rollers 15 and 19 to be moved upwardly to the position shown in the dotted lines in Fig. 1. This results in the linkage moving the swinging lever 18 to the position shown in the dotted lines in Fig. 1 so that the piston 23 of the setting mechanism 21 is moved to the right against the air pressure acting on its righthand side. Since the pawl 35 is withdrawn from the teeth 30 by air pressure acting on the upper side of the piston 36, the piston 28 will also move to the right under the influence of its spring 34 and so re-position the roller 31 along the weigh beam 32.

[Class 56] Tin or its compounds is added during manufacture to fused silica, or to glass which transmits ultraviolet radiation, in order to control the wavelength below 3000 A.U. at which absorption of the radiation becomes appreciable. Stannic oxide may be used for the purpose, and the amount to be added to the raw material varies according to the thickness of the finished articles, generally between 0À2 and 2À0 per cent. When producing transparent fused silica, the tin compound is mixed with the sand or crushed quartz and the mixture is fused under atmospheric pressure. The fused mass is then pulverized, and after treatment to remove iron or other impurities, the powder is fused again under reduced pressure to produce a transparent mass.

Abstract: A tamping-tool unit (3) consists of two tool-holding devices (20) which are in each case mounted pivotably about an axis (22) running transversely to the longitudinal direction of the machine. These devices are designed as essentially fork-shaped pivot levers with a pivot bearing (23), a forked drive arm (24) extending upwards from the latter, and two side arms (25, 26) extending below the pivot bearing (23) transversely to the longitudinal direction of the machine to opposite sides of the vertical longitudinal plane of the rail. Arranged on the outer side arms (25) are tamping tools which are movable only in the longitudinal direction of the track, intended for submerging in adjacent sleeper compartments and together form a tamping-tool pair (29). In order to be able to avoid track components which are in the way, in particular in the crossing and points region, the tamping-tool pair (30) lying on the inside of the rail is additionally designed to be laterally pivotable about an axis running in the longitudinal direction of the machine. <IMAGE>
