Patent GB-495184-A (GB)
Title: Improvements in the catalytic polymerisation of olefines
IPC: C07C2/08
Filed: 1937-03-04
Abstract: In the catalytic polymerization of gaseous olefines in a plurality of consecutive reaction vessels, the reaction products from each vessel are passed to the next without substantial interstage cooling but with removal of at least a substantial portion of constituents which in the said vessel are in the liquid state.  Preferably the same temperature and pressure prevail in the intermediate separating vessel as in the reaction vessel.  The temperature may, however, be higher, and is advantageously increased with the pressure used in the separation.  Thus, if at 20 atmos. a temperature above 120 DEG  C. is required, at 50 atmos. it is usually above 200 DEG  C.  Generally from 2 to 8 reaction vessels are employed.  In examples: (1) a gas containing propene and butene is passed at 200 DEG  C. and 20 atmos. through reaction vessels charged with phosphoric acid on activated wood charcoal.  Behind each vessel is a separator at 180 DEG  C. in which the liquid level is p  automatically maintained.  The last separator may be at a lower temperature whereby gaseous paraffins dissolve in the polymer; (2) the gas is at 200 DEG  C. and 50 atmos., and the separators at 250 DEG  C.

Title: Improvements relating to devices for gauging dimensions
IPC: G01B3/18
Filed: 1943-04-16
Abstract: 559,143. Linear dimension gauges. WILKINSON, S., and GREEN, A. April 16, 1943, No. 6782/42. [Class 106 (ii)] A linear-dimension gauge of the kind comprising a pair of gauging members, one of which is movable, indicating means, and motion magnifying means whereby a small change in the dimension of the article to be tested is readily measured and observed, is characterized in that a lost motion connection is provided between the movable gauging member and the indicating means, means being provided for adjusting the position of the movable gauging member relative to the gauge at which said lost motion is taken up and movement transmitted from the gauging member to said indicating means, whereby irrespective of variations in the dimension to be tested, motion may be transmitted to said indicating means only when the movable gauging member approaches the surface of the article to be tested. A calliper gauge has a primary gauging member 51 slidable in a tubular body 10, the outer end of which is stepped as at 15 and closed by a cap 17 held in place by a flanged tubular member 21, the thread 22 of which engages the incomplete thread 16 of body 10. The end of the slide 51 abuts against an adjustable screw 68 in a push button 60 slidable in the member 21 and having a screw engagement with the split portion 54 of a collar 52, frictionally adjustable on the slide 51. A pin 56 projects from the collar 52 through a slot in a plate 31, secured to the body, and acts on a lever 37 which actuates a lever 35 of spring metal having its end fixed in a groove 34, so that when the lost motion existing between the pin 56 and the lever 37 has been taken up by movement of the button 60, any further movement of the pin 56 is greatly magnified on a scale 42. Adjustable clips 46 may indicate permissible tolerance. In use, members 21 and 26 are unscrewed to allow adjustment of the collar 52 along the slide 51, and are then replaced. A secondary gauging member 64 is adjusted until with the test piece in position and the push-button 60 pressed in, the needle indicates zero. Variation from standard of subsequent articles are shown on the scale. The device may be adapted, Fig. 2 (not shown), for use as a depth gauge, a second scale 45 being provided with plus and minus reversed. In a modification, Fig. 8 (not shown), the member 64 is replaced by an ordinary micrometer gauge, the scale being modified in this case to read from 0 to 10. In a further modification, Fig. 9 and Fig. 10 (not shown), the body 10 is secured to a micrometer shank, the slide 51 passing through. In use, the body 10 is turned until the micrometer has been set with a line 78 exactly opposite a whole scale division 77. Operation of the button 60 then gives the equivalent of a vernier reading.

Title: Process for the preparation of terephthalic acid
IPC: C07C51/265
Filed: 1954-03-11
Abstract: A process for preparing terephthalic acid comprises reacting in the liquid phase para-diisopropylbenzene with molecular oxygen in the presence of a catalytic amount of a heavy metal compound, the reaction mixture being at least 10 per cent saturated with water, at a temperature in the range of 150 DEG  to 275 DEG  C. and a pressure in the range of 100 to 1500 p.s.i.g.  The reaction may be carried out in the presence of a non-acid organic liquid, e.g. an aromatic or aliphatic compound boiling in the range 50 DEG  to 450 DEG  C. at atmospheric pressure and stable under the reaction conditions, e.g. halogenated, e.g. chlorinated, polyphenyls, especially chlorinated biphenyls, biphenyl, diphenyl ether and naphthalene. The starting material may contain meta-di-isopropylbenzene and lower or higher alkylated benzenes or saturated aliphatic hydrocarbon material relatively resistant to oxidation in the system.  Pure oxygen or gas mixtures containing oxygen may be used.  The temperature and pressure are selected so that the desired amount of liquid water is maintained in the system.  The process may be carried out batchwise or continuously.  In examples: an agitated mixture of paradi-isopropylbenzene containing some metaisomer, water and manganese cumate is treated with oxygen at elevated temperature and pressure sufficient to maintain a liquid water phase present, the terephthalic acid is filtered off and washed with acetic acid and esterified directly with methanol using hydrochloric, sulphuric or phosphoric acid as catalyst, or the crude acid may be washed beforehand with methanol, ethanol or propanol, or the crude acid may be converted to the corresponding chloride with thionyl chloride and the chloride heated with methanol (1); and in a similar process chlorinated diphenyl is included in the oxidation reaction mixture (2).  Isophthalic acid is obtained by distillation of the acetic acid washings.  Metal carboxylate catalysts may be prepared by reacting the metal oxide or other compound with the appropriate organic acid or the latter may be dissolved in caustic alkali with the subsequent addition of an aqueous solution of the appropriate metal acetate. Manganese cumate is prepared by the latter process.
