Title: Process and apparatus for the recovery of sulphur
Inventor: TISDEL L C
IPC: C01B17/033
Filed: 1970-06-23
Abstract: 1314858 Heat exchange crystallization BRAMEDA RESOURCES Ltd 23 June 1970 [27 June 1969] 30490/70 Heading BIG [Also in Division C1] A process for crystallising sulphur from its solution in a solvent which is immiscible with and more dense than water comprises passing said solution down a crystallisation zone in countercurrent flow to a stream of aqueous heat exchange liquid introduced at a series of points spaced vertically below the point of introduction of the sulphur solution, allowing the solvent and aqueous liquid to separate in the crystallisation zone to form an interface above the level of introduction of the sulphur solution, removing heat exchange liquid from a point above said interface and a slurry of crystalline sulphur in lean solvent from the bottom of said crystallisation zone and maintaining the temperature of the aqueous liquid introduced below that of the sulphur solution into which it is introduced and also below that of the aqueous liquid introduced at the next highest level and separating crystalline sulphur from the product slurry.  A preferred embodiment of the claimed apparatus comprises a vessel 40 divided into a series of zones by baffle plates 46, each zone being provided with an agitator 43 and an inlet 50 for heat exchange liquid. Sulphur solution is introduced from line 82 and product sulphur slurry is removed through line 90, sulphur being separated from lean solvent in separator 94. Heat exchange liquid introduced through inlets 50 coalesces to form interface and is withdrawn via line 68 and the stream of liquid is then divided. One portion is recycled directly to inlets 50 via line 62 whilst the other is cooled by passing through heat exchangers 58 and 60 before returning to inlets 50 via line 56 where, by adjusting the ratio of liquid returned via line 56 to that returned via line 62, fine control of the inlet temperature can be obtained. Cold lean solvent from separator 94 may be passed to heat exchanger 60 via line 104 to cool the spent heat exchange liquid.

Title: A hydraulic device for brakes
IPC: F16D65/74
Filed: 1961-08-24
Abstract: 940,515. Hydraulic brakes; valves. BENDIX CORPORATION. Aug. 24, 1961 [Sept. 6, 1960], No. 30564/61. Headings F2F and F2V. An automatic adjusting device 10, more particularly for use in aircraft brakes, comprises two chambers 36, 52, one 36 of which is operatively connected to a source of fluid pressure, e.g. pump 16, and the other to brake 23, the device 10 being characterized by a flow limiting means. The flow limiting means interconnects chambers 36, 52 and includes an orifice 121 and a pressure responsive member 136 having a portion 138, 142, 143 thereof controlling the effective metering area of orifice 121. Member 136 is movable by differential pressures in chambers 36, 52 to throttle the flow through orifice 121 by an amount regulated by the pressure drop between the chambers the effective metering area being decreased as the pressure difference increases. The device 10 comprises a stepped cylinder, two intersecting pistons 40, 48, piston 40 possessing the flow limiting means and piston 48 being adapted to act within skirt 44 of piston 48 and carrying a normally closed, spring loaded poppet 76. The two pistons are normally biased to the left as seen in Fig. 1 by springs 66, 68. Chamber 56 possesses a screw abutment 90 at its end with which poppet 76 may co-operate. Chamber 58 between piston 40 and the cylinder is vented to air through valve 60, 62. Pressurized fluid passes from pump 16 to chamber 36 moving pistons 40, 48 to the right until the former engages abutment fence 164 when fluid, passing through the limiting means by ports 116, 118, 121, 124 into chamber 52 effects the continuance of the motion of piston 48 until poppet 76 engages abutment 90. The poppet then opens allowing pressurized fluid to operate brakes 23. When the brakes are released fluid is withdrawn from the brakes by the retraction of the two pistons 40, 48. If wear has taken place then, to retain the initial brake clearance, more fluid is introduced into chamber 56 by pumping device 10 until poppet 76 is opened again by abutment 90. If the brake expands due to heating, the excess pressure in chamber 56 opens poppet 76 against spring 82 and fluid escapes through a cheek valve 96. Three flow limiting means are described in two of which shaped, spring loaded metering members 136 and spool 250 (Fig. 6, not shown) are used. These move in their respective orifices metering the flow in accordance with a square law. The third means comprises a stationary member 322 (Fig. 11, not shown) possessing a conical end portion which passes through an orifice in a flexible diaphragm, a pressure differential over the diaphragm causing the cone to move relatively to, and within the orifice. If a failure occurs downstream of the device 10 then the flow limiting means allows only an acceptable amount of fluid to be lost from the system.

Title: Improvements in or relating to hydraulic controlling means, more particularly for the landing gear of aircraft
IPC: B64C25/22
Filed: 1939-11-24
Abstract: 576,115. Hydraulic control systems ; hydraulic accumulators. BOYSSON, J. B. A. DE. Nov. 24, 1939, No. 30754. Convention date, Nov. 25, 1938. [Class 69 (ii)] For controlling the landing carriages 14, Fig. 1, of aircraft hydraulically by moving them from an operative position shown in full lines to an inoperative position shown in dotted lines, the jack 16 is connected to the pressure fluid supplied by a pump 1 by means of a valve 8 which is opened by the piston 5 of an accumulator 4 only when sufficient liquid is stored in the accumulator to effect the reverse operation of the carriage. When the valve 21 is set as shown in Fig. 1 and the valve 8 is opened, both ends 19, 20 of the jack 16 are connected to the chamber 7 of the accumulator, but the liquid admitted by pipe 22 acts on a larger area of the piston and so operates the piston-rod 18. On reversing the valve 21 through 90 degrees, the pipe 12 is cut off and liquid from the end 20 can return via pipe 24 to the tank 2, and liquid from the accumulator 4 passes into the end 19 and returns the piston 17 to the position shown. The piston 5 is acted upon by a spring or compressed air. In a modification, Fig. 2, the carriage 35 is retracted when the pipe 29 is connected to pipe 12 by a small clockwise rotation of the valve 23 and in this position the pipe 28 is connected to the pipe 24 leading back to the tank 2. In the position shown, the pipe 28 is connected to the pipe 13.and the carriage is not retracted. In further modifications, one accumulator may serve a number of actuating-devices for operating carriages of aircraft or other objects, or the accumulator 4 may be associated with an auxiliary accumulator which controls the valve 8. As shown in Fig. 5, the accumulator 4 is divided into two parts separated by a partition 47 in which is a stop valve 48, and the pipe 13 leads from the upper compartment. The valve stem of valve 8 passes through a packing 49. Such a construction prevents chattering.

R1 and a catalytic amount of an aromatic sulphonic acid at a temperature below 100 DEG  C. while simultaneously distilling off the resultant esters of the formulae R1C(O)OCH3 or R1C(O)OC2H5 and causing to be present during the reaction the amount of water required for complete hydrolysis and siloxane condensation, neutralizing the catalyst with an excess of alcoholic alkaline solution, filtering off the precipitated salt, freeing the filtrate from volatile components and refiltering to clarify.  Suitable catalysts are benzene sulphonic, p-chlorobenzene sulphonic and p-toluene sulphonic acids and alcoholic potassium hydroxide is used to neutralize the catalyst. The filtrate is freed from volatile components by evaporation under reduced pressure, in a current of carbon dioxide, at 20-30 DEG  C.  Examples of R are methyl and phenyl.  The reaction may be carried out such that water is obtained in situ, for example by reacting an acyloxy-silane R1-COOCH2-Si(CH3)2-OOC-R1 and an alkoxy-silane R1-COOCH2-Si(CH3)2-OC2H5 with methanol the first reactant producing water on alcoholysis and the second requiring water for alcoholysis; or water may be added to the reaction mixture.  When the acyloxymethyl silicon compound is a silane, the heating may be carried out in the presence of a condensable silane R4- mSi(OH)m or siloxane consisting of units R2Si(OH)O 1/2 and optionally units <FORM:1121265/C3/6> or in the presence of a hydrolysable silane R4- mSi(OR111)m or siloxane consisting of units R2Si(OR111) 1/2 and optionally units <FORM:1121265/C3/7> and water.  In the examples, 1,3-di-(hydroxymethyl) - tetramethyl - disiloxane and a linear methylpolysiloxane which is hydroxymethyl substituted in the lateral position are obtained.
