摘要： 1,033,669. Screw conveyer. H. J. ZIMMER. Dec. 7, 1962 [Dec. 7, 1961], No. 46293/62. Heading B8A. [Also in Division B1] A conveyer suitable for carrying out a chemical reaction (see Division B1) comprises at least two enmeshing worms supported horizontally in a container, the lower part of which closely surrounds the worms, an inlet and an outlet; wherein (a) the worms are of the same pitch, of the same hand and the relative phases of which are such that when rotated there is at least some interengagement to effect mutual self-cleaning, (b) the flanks of the worms have radii of curvature equal to the distance between the axes of adjacent worms (f, Fig. 8) and (c) the centre of curvature of each flank is at a distance from the axis equal to the greatest radial dimension of the adjacent worm (g, h, Fig. 8). As shown in Fig. 2, material is introduced through inlet 41 and removed from outlet 42 by means of a further conveyer screw 67 and a vacuum is maintained in the apparatus, being applied through the outlet 44. The worms are driven by motor 52 through suitable gearwheels (see Fig. 4, not shown). Heating jackets 46, 47 and 48 surround the chamber. The illustrated apparatus has three worms supported in a horizontal plane. The worms may be of various kinds, and may or may not be identical. Thus Figs. 5 and 6 illustrate identical worms, those in Fig. 5 being similar to that shown at 19 in Fig. 8 and those in Fig. 7 being similar to that shown at 20 in Fig. 8. Fig. 9 shows a pair of similar worms having a " negative " core radius, i.e. having the shape of spirally wound worms wrapped around a cylindrical space. In Figs. 10 and 11 there are shown worms in which, considering a cross-section of the worm, the surface of the worm lying on the outer periphery thereof is reduced in length so that phase displacement of the worms is possible. By intermittently producing such phase displacement, opposite sides of the worms may be scraped. This phase displacement may be performed by temporarily changing the relative speeds of rotation of the worms for a predetermined time, e.g. by temporarily halting the rotation of one of the worms. Alternatively, the phase displacement may be achieved by linearly displacing one of the worms. Fig. 2 shows an arrangement for achieving this linear displacement comprising a piston operating in a cylinder 64 having means 65, 66 for admitting fluid to opposite sides of said piston, the axis of the worm being such as to slide through the centre of the gear 54 whilst being forced to rotate therewith: the gear-wheel 54 itself is held against axial displacement.

摘要： In the manufacture of polyethylene terephthalate by effecting an ester-interchange reaction between dimethyl terephthalate and ethylene glycol and thereafter polycondensing the product, there is used as a catalyst for the polyesterification reaction an organo-tin compound of formula in which R1 and R2 are alkyl, aryl, alkaryl or cycloalkyl groups and R3 and R4 are the radicals of semi-esters of aliphatic, aromatic or hydroaromatic dicarboxylic acids which are connected to the tin atom through the non-esterified carboxyl groups of the semi-esters. Specified radicals for R3 and R4 are those of maleic, adipic, pimelic or terephthalic acid esterified with C1 to C6 aliphatic alcohols.

摘要： 1, 008, 284. Pressure gauges. H. J. ZIMMER. Dec. 28,1962 [Dec. 28,1961], No. 48870/62. Heading G1L. In a fluid pressure device comprising first diaphragm 2, located in a pipe wall 5 and exposed to the fluid pressure in the pipe 1, and a second diaphragm 3, exposed through an aperture 13 to atmospheric pressure the arrangement is such that both diaphragms 2 and 3 are mounted in cylindrical metallic elements 8 and 9 in heat conducting relationship with a housing 4 so as to be at substantially at the same temperature. The ends of the elements 8, 9 behind the diaphragms 2, 3 are conical, Fig. 2 (not shown), so the diaphragms are not deflected beyond their elastic limit.

摘要： In the manufacture of polyethylene terephthalate by transesterifying dimethyl terephthalate with ethylene glycol and subsequently polycondensing the product, there is used as a catalyst in the polyesterifaction reaction an organic mercapto tin compound of formula wherein R1 is an alkylmercapto group, R2 is an acyloxy group and R3 and R4 are alkyl, aryl, alkaryl, aralkyl or cycloalkyl radicals. The transesterification reaction may also be effected in the presence of the tin catalyst. Specified catalysts are dodecylmercapto-dibutyl-tin stearate, dodecylmercapto-dibutyl-tin laurate, dodecylmercapto-dibutyl-tin-ethyl ester maleate hexylmercapto - dimethyl - tin crotonate, hexylmercapto - methyl - hexyl - tin crotonate and butylmercapto - dibutyl - tin methyl ester maleate. Specification 810,381 is referred to.

摘要： A catalyst solution comprising cuprous chloride, used in the production of acrylonitrile from C2H2 and HCN, is regenerated by contacting the catalyst liquid in fine dispersion with hot gases (e.g. by spray-drying) and adding solvent to the resultant dry salt. The method may be applied to a continuous process by continuously withdrawing and regenerating a portion of catalyst. The catalyst specified contained the chlorides of copper, potassium, sodium and cobalt, and HCl; ammonium chloride is also mentioned as a catalyst constituent.

摘要： 897,283. Electrolytic testing apparatus ZIMMER, H. J., [trading as ZIMMER VERFCHRENSTECHNIK, HANS J.]. March 17, 1961 [March 17, 1960], No. 9823/61. Class 37. Oxygen in a gas is determined by measuring the depolarization current in a galvanic cell having a partially immersed cathode and a wholly immersed less noble anode, the gas being introduced into the electrolyte through a gas diffuser situated above the anode and below the cathode, such that the gas is directed to pass over the surface of the cathode but does not reach the anode. Head C for electrolyte container B has an electrolyte inlet tube c, and gas outlet and inlet tubes b and a, the latter communicating with a gas feed tube D which contains a lead supporting the anode A, and the outside of which is surrounded by and supports a sheet or wire net cathode K, of uniform circumference and preferably of silver or gold. Gas passing from tube D into the electrolyte E is directed towards the cathode by the sintered glass diffuser F mounted in a glass cup. A microammeter is connected between the electrodes.

摘要： 891,115. Yarns and threads. ZIMMER, H. J., [trading as ZIMMER VERFAHRENSTECHNIK, HANS J.]. Sept. 2, 1960 [Jan. 30, 1960], No. 30410/60. Class 120(3) [Also in Group XXXIV] Cords for pneumatic tyre reinforcing fabric comprise linear polypropylene filaments which have been pre-treated by hot or cold drawing, the drawn staple fibre yarns, or monofilaments being twisted into cords and subsequently, redrawn. The filaments may comprise a mixed polymerizate of 80% polypropylene and 20% other olefinic material and may include a heat stabilizer. The filaments or yarns, or the completed cord, may be thermofixed at a temperature of 100‹ to 130‹C. In a particular example, hot drawn, thermofixed polypropylene thread having 125 strands and a total titer of 750 denier is subjected to a Z-twist of 400 r.p.m. and then twisted with a similar thread to impart an S-twist at 420 r.p.m.

摘要： Cyclohexanone is produced in good yield by passing a mixture of cyclohexylamine and water vapour, at a temperature of 100 DEG -180 DEG C., over a catalyst comprising copper oxide and chromium oxide and/or zinc oxide which, before use, has been reduced in a stream of hydrogen. In an example, a mixture of 69-71% of copper oxide, 29-30% zinc oxide and 0-2% chromium oxide is ground together, and thereafter reduced at a temperature of 250-350 DEG C. in a stream of hydrogen. A mixture of cyclohexylamine and water vapour in a mol ratio of 1 : 12 is then conducted over the catalyst at a temperature of 160 DEG C. The product contains cyclohexanone together with a minor proportion of cyclohexanol.
