Title: Method of treating a substance to produce vitamin d therein
IPC: A61K31/592
Filed: 1937-09-21
Abstract: <PICT:0497165/IV/1> <PICT:0497165/IV/2> <PICT:0497165/IV/3> <PICT:0497165/IV/4> Ergosterol or other anti-rachitically activatable substances are treated to produce vitamin D by subjecting the vapour of the substance, obtained by heating under reduced pressure, to a silent non-luminous flow of electricity, for which the vapour serves as conducting medium, and condensing the activated vapour.  The vapour may also be subjected to a field of electrostatic and electromagnetic force.  The reaction may be assisted by the presence of metallic indium, which is heated with the ergosterol. In the apparatus shown in Fig. 1, the ergosterol 3 is heated in an evacuated tube 1 provided with electrodes 4, 5 and a condenser 8.  In the form shown in Fig. 2, the electric flow in the evacuated tube is produced by current flowing in a coil 12.  The methods of Figs. 1 and 2 are combined as shown in Fig. 3, in which the electrodes 13 are connected to coils 12.  In a further construction, Fig. 4, electrodes are provided in tortuous lateral tubes 19, 20 extending from the main tube 1 which is surrounded by discontinuous coils 23, 24.  A mass of indium 25 is placed at the base of the tube.  The electric current used may be alternating or pulsating unidirectional and is of high frequency.  After completion of the process the activated material is removed by washing out the tube with a solvent such as ether.

Title: Improvements in or relating to fluid-pressure relief valves
IPC: F16K17/10
Filed: 1940-09-11
Abstract: 540,596. Relief valves. COSTA, H. DA., and PLESSEY CO., Ltd. Sept. 11, 1940, No. 25596/39. [Class 135] A relief valve particularly adapted for use with cartridge-operated starters for internal combustion engines has a piston-actuated main valve controlled by a pilot valve which is spring-loaded to the maximum required pressure and when opened is maintained open by a lower pressure. The main valve 14 which is housed in a strainer 16 formed by a slotted extension on a removable cover 15 is rigidly secured to a hollow piston 19 housing a spring 21 bearing against a washer 22 supported by a shoulder on the casing. The pilot valve 29 co-operates with a removable seat 26 having a slotted extension 27 to form a strainer and is loaded by a spring 34 arranged between an adjustable abutment 35 and a washer 33 resting on a shoulder in the pilot valve spindle. An actuating piston 30 has an inturned flange 37 movable with slight lost-motion between the valve head and the washer so that after a slight initial opening of the pilot valve the pressure transmitted through a passage 24 to the main actuating chamber acts on the piston to move the pilot valve rapidly to its full open position and maintain it open until the pressure has dropped to a predetermined minimum. When the pilot valve closes pressure in the main actuating chamber escapes through a vent 40. The washer 30 is provided with a spring ring 38 to hold the piston in contact with the washer during the return movement of the pilot valve.

Title: Improvements in processes for extracting precious metals from silicates
IPC: C25C1/20
Filed: 1954-09-06
Abstract: 800,809. Fused electrolyte processes. COMPAGNIE FRANCAISE DE METALLURGIE AURIFERE. Sept. 6, 1954 [Sept. 9, 1953], No. 25827/54. Class 41. A process for extracting precious metals such as gold, silver and platinum from a silicate mineral comprises fusing the mineral and electrolysing it in the presence of a flux, e.g. of alkali metal salts, and a halogen, hydrogen halide, metal halide, or a mixture of compounds capable of forming such a substance, whereby decomposition of the silicate and liberation of the precious metal is effected. The halogencontaining addition may be manganese dioxide and hydrochloric acid but is preferably fluorinecontaining, e.g. cryolite, sodium fluoride, hydrofluoric acid or a mixture of calcium fluoride and sulphuric acid. The ore may be preliminarily treated to remove components such as sulphur or arsenic which would interfere with the electrolysis, by physical means such as gravity separation, or chemical means such as oxidation, reduction or chlorination. There may be introduced into the fused bath gases or other materials which assist in eliminating undesirable components, e.g. hydrogen, oxygen, water vapour, hydrogen sulphide, sulphuric acid, nitric acid or sulphurous acid. Apparatus for carrying out the invention shown in the Figure, comprises a crucible 1, to contain the fused mineral, a tubular anode 2 through which gases can be injected, and a carbon cathode 3 in an insulating refractory tube 4. In an example a mixture of silicate mineral containing small amounts of gold and silver with cryolite, sodium sulphate, and litharge was treated, the electrolysis resulting in the formation of a layer 5 of lead containing gold and silver.

Abstract: 838,440. Angular bending. HILGERSMASCHINENUND APPARATE BAUANSTALT. Aug. 24, 1956 [Sept. 5, 1955], No. 26017/56. Class 83 (4). A tube bending machine in which the tube is bent around a driven rotatable bending pattern and which includes a slide adapted to bear transversely against the unbent part of the tube clamped to the pattern is characterized in that the slide is held in a neutral or initial position by two pre-tensioned springs acting in opposite directions to one another and is moved from this position to press against the unbent part of the tube by lever means before bending commences. A slide 18, held by two pre-tensioned springs 20 each secured at one end to the machine frame 10 and at the other end to an adjustable plate 21 on the slide, carries, clamped thereto by bolts 17, a member 15 in which are mounted two rollers 14 adapted to engage the unbent part of a tube clamped to a bending pattern 13. In operation, at the beginning of the rotation of a table I the tube is clamped to a straight part 13a of the pattern 13 and just before said clamping is completed, a recess 28 in the periphery 27 of the table 11 has moved past a roller 26 which bears against the periphery. The roller 26 is carried by a lever 24 pivoted to the machine frame and engaging the slide 18 at its other end 29 so that on such movement out of the recess 28 the slide is moved to the right to cause the rollers 14 to press against the unbent part of the tube. Rotation of the pattern 13 then causes the tube to be bent therearound. When the desired angle of bend has been produced the table 11, but not necessarily the pattern 13, is rotated in the opposite direction first to unclamp the tube then, when the recess again engages the rollers 26, to move the slide 18 and rollers 14 to the left back from the tube and then, on continued rotation of the table 11 when the roller 26 again leaves the recess 28, to move the slide 18 and rollers 14 further back from the tube. To produce bends of opposite hand the member 15 is clamped to the slide 18 at the other side of the pattern 13 and the table 11 and pattern 13 are rotated in the other direction.

Abstract: 643,266. Vehicle suspensions. OSTER, L. E. W. MONTROSE-, and POLLOPAS PATENS, Ltd. Oct. 6, 1945, No. 26083. Convention date, Jan. 20, 1943. [Class 108(ii)] A self-stabilizing suspension system for a four-wheeled vehicle comprises at each side of the vehicle a conjugate suspension system in which the front and rear wheels are connected together, the connection serving also as the resilient member of the conjugate suspension on that side of the vehicle, the two lateral resilient conjugate suspensions being interconnected by a resilient member whose flexibility is a multiple of that of the resilient members of the conjugate suspensions. The self-stability may be produced either by arranging for a restoring couple to be produced and increased by angular movement of the vehicle about a transverse axis, or by a restoring -couple produced by the resilient interconnection between the central points of the two lateral conjugate suspensions, or by a combination of both. As shown in Fig. 1, the front wheel is sprung by torsion bar 19, arm 11 and link 14, and the rear wheel by torsion bar 20, arm 13 and link 15. The adjacent ends of bars 19 and 20 are secured to a lever 12 pivotally mounted in bracket 3 and whose end engages a transverse coil spring 18, the arrangement being repeated on the other side of the vehicle. Instead of there being two separate torsion bars there may be one long bar on each side of the vehicle. Fig. 5 shows the invention applied to a vehicle with independent suspension. Each wheel is carried by a pair of arms 24, 25 or 26, 27 having universal joints at each end. Each upper arm is connected by a ring-shaped member 39 or 40 to a lever 36 or 38 secured to the end of a pair of torsion bars 41, 42 connected rigidly at their adjacent ends to the lever 37 which bears on the transverse coil spring 43.
