Title: Improvements in or relating to gas purification
Inventor: COUSIN PHILIPPE
IPC: B01D5/00
Filed: 1963-09-25
Abstract: 1,017,637. Separating gases by liquefication  and diffusion. COMMISSARIAT A L'ENERGIE ATOMIQUE. Sept. 25, 1963 [Sept. 25, 1962], No. 37787/63. Heading B1L. Gas mixture containing a condensable gas and a less-condensable impurity, are separated by compressing and cooling to remove the condensable gas, the gaseous phase rich in impurities remaining is then subjected to a diffusion process to remove the impurities. In an apparatus for carrying out the process of the invention gas is compressed at 1, cooled at 2 and the liquid phase withdrawn at 4 from reservoir 3. The vapour from the reservoir is fed into a diffusion cascade system at 6. If the impurities have low molecular weight, then they are withdrawn at 8 whilst the heavy fraction is withdrawn at 9 and may either be returned to the compressor 1 or the liquid phase at 4 according to the purity of the effluent. The pressure in the reservoir 3 and the cascade are controlled by stabilizers 11 and 18 with associated valves 10 and 17 respectively. The gaseous mixture at 6 is compressed at 13 before going to diffusion chamber 14 which is divided into two parts by the membrane 15. The compressors of the cascade may be centrifugal. The purification of a mixture of UCl 6 , ClF 3  and N 2  is referred to.

Class 20(2) A telescopic pit prop comprises an inner tube 11 to which is clamped a collar 13 which rests on a flange on an outer tube. The collar 13, which has at its ends tangential lugs 17, 18 which lie side by side and are surrounded by an oval shackle 19, can be tightened by a wedge 20 which bears on the inside of the shackle 19 and on the outside of the lug 17, so as to force the inclined faces 26, 27 of the lugs together causing the lugs to move longitudinally. The shackle 19 fits behind an abutment 27 on the lug 18 and has a slot which receives a projection from the lug 17. When disengaged a recess 22 of the wedge 20 allows the shackle 19 to be removed. A stop 23 prevents withdrawal of the wedge 20. In a modification, relative movement of the lugs 18, 17 is effected by a pinion on one engaging rack teeth on the other.

Abstract: 840,566. Discharging coke-oven batteries. OETIKER, H. Dec. 13, 1957 [April 25, 1957], No. 38781/57. Class 51 (2). In discharging a horizontal cokeoven battery C, pneumatically-operated equipment is provided to ensure that the coke guide machine A, the coke pusher machine B and the coke car D are correctly positioned prior to the discharge of coke from an oven 27. When the machines are correctly aligned and ready for discharging, compressed air from a reservoir 1 or a spare reservoir 2 on the coke guide machine A actuates a pressure switch 17 on the cokepusher machine B to energize relays 25 and 26 associated with a reversible switch 24 controlling the motor 22 actuating the pusher ram 23. The pneumatic system on the guide machine A comprises a coupling 3, 4 making connection with the reservoir 1 or 2, a foot-operated valve 5 opened by the coke guide operator, a valve 6 opened by a button 29 contacting a fender 28 on the coke car D, a valve 7 opened when the doors 9 of the coke shoot 8 are closed, and a cylinder 10 closing a coupling 11, 12 interconnecting the system with a pipe extending over each oven. The pneumatic system on the pusher-machine incorporates a reservoir 19 with a spare reservoir 20 operating a cylinder 15 through a foot valve 16 opened by the coke-pusher operator to close a coupling 13, 14 interconnecting the system with the said pipe extending over the oven. Coupling ports 3, 11 and 13 incorporate spring-pressed valves respectively opened by the introduction of coupling parts 4, 12 and 14. When the pneumatic system is operated, air passes through a non-return valve 18 to maintain the pressure in the reservoir 19 or 20.

Title: A process for recovering terephthalic acid from aqueous solutions of dialkali metal terephthalate
IPC: C07C51/02
Filed: 1957-12-18
Abstract: The invention comprises a process for the recovery of terephthalic acid from an aqueous solution of a dialkali metal terephthalate by passing sulphur dioxide into the solution, separating the precipitated terephthalic acid, and heating the resulting aqueous solution of alkali metal bisulphite in the presence of an amount of a benzene carboxylic acid other than terephthalic acid at least stoichiometrically equivalent to the alkali metal bisulphite, thus forming an alkali metal salt of said benzene dicarboxylic acid in solution.  The dry salt recovered from this solution may be transformed by heating into the corresponding salt of terephthalic acid.  The starting solution should preferably contain from about 5 to about 20 per cent by weight of dialkali metal terephthalate, and the sulphur dioxide is passed into the solution at preferably 0-100 DEG  C. until it ceases to be absorbed.  The terephthalic acid precipitated may be removed, e.g. by filtration or centrifugation leaving an aqueous phase containing alkali metal and bisulphite ions in solution, to which a benzene carboxylic acid other than terephthalic acid is added.  This acid may be added stepwise, in an amount preferably at least about 5 per cent in excess of the amount stoichiometrically required, the excess at the end of the reaction being neutralized with an alkali metal hydroxide if desired, to form additional reactant for subsequent conversion into dialkali metal terephthalate.  The second step is preferably carried out between 80 DEG  C. and the boiling point of the reaction mixture, which may be up to about 300 DEG  C. if superatmospheric pressure is used.  The reaction mixture may be sparged in the second step with e.g. nitrogen, argon, or carbon dioxide.  It is preferable to remove water during the course of the reaction, e.g. by boiling the reaction mixture and allowing the water vapour to escape along with sulphur dioxide.  The sulphur dioxide evolved may be recycled to the first step in the process.  Examples are given using dipotassium terephthalate and disodium terephthalate as starting materials, and benzoic acid and phthalic anhydride as the acids in the second step of the reaction.  Other alkali metals specified are lithium, rubidium and caesium.  Specifications 744,721, 747,204, 762,448, 762,644, 774,497, 777,609 and 819,281 are referred to.

In a phased aerial array, each element in a line thereof is fed from separate selectively variable delay means controlled by a counter having outputs of differing orders and corresponding in number to the number of elements in the line, and clock pulses are applied during a time gate proportional to the desired angle of radiation. The embodiment utilizes a twodimensional array of modules (14, Fig. 1) similar to the kind described in Specification 1,124,266. Each module includes a phase shifter 31, Fig. 4 having delay sections 100 . . . 103 in an R.F. path, and being selectively brought into circuit by corresponding switches 104 ... 107; the switches are energized from a counter 111 fed from the point y, Fig. 5. Azimuth and elevation time gate pulses are fed in at respective terminals 133, 134 to AND gates which are fed also at terminal 132 with clock pulses. Azimuth and elevation respective binary circuits 135, 136 (decsribed with reference to Fig. 6, not shown) are associated with switches to produce pulses into " quantizers " in the ratio 1, 2, 3 ... 28 (the aerial array being formed from a 28 by 28 matrix of elements), and the quantizers count down by a factor of 8. Each counter 111, Fig. 4 is associated with a different output of a NAND gate matrix 140, Fig. 5. Voltages on lines 146, 147 determine whether a beam is to be switched left or right of boresight (the magnitude of the beam deflection being determined by the width of the pulse applied to terminal 133) and similarly for beam deflection above and below boresight. A diagram of the switches and quantizers is described, Fig. 7 (not shown). A modification is described, Figs. 8, 9 and 10 (not shown).
