Liquid is distilled by feeding it through inlet 3 on to a glass or ceramic cylinder 1 which is heated by an electric device (not shown) and is surrounded, with slight clearance, by a glass or ceramic helix 6 which rotates and thereby distributes the liquid as a uniform film over the surface of the heated cylinder and also moves the film in a downward direction. The cylinder is arranged in casing 2 which is maintained under vacuum. Some of the liquid evaporates, and the vapours condense on the casing, the distillate flowing down to groove 9 and being withdrawn through outlet 5. The distillation residue is withdrawn through outlet 4. The base of helix 6 is connected to a magnetic core 8 ; and the rotation of the helix is achieved by a rotating electromagnet 7 outside the casing, e.g. at 30-50 r.p.m. If desired, the helix could be fixed, and the cylinder 1 made to rotate.

Title: Production of naphthalene and benzene
Inventor: MASON JOSEPH CROWDER
IPC: C10G65/10
Filed: 1963-02-08
Abstract: Benzene and naphthalene are obtained from an aromatic feedstock boiling in the range 200-600 DEG  F. and containing alkylbenzenes and alkylnaphthalenes by subjecting the feed to a first hydrocracking step which effects cracking of non-aromatic hydrocarbons without effecting dealkylation and operated thermally at 1000-1100 DEG  F., 150-1000 p.s.i.g., 2-300 seconds and hydrogen to hydrocarbon mol. ratio of 3-25:1 or catalytically at 800-1100 DEG  F., 150-1000 p.s.i.g., 0.2-10 vol./vol./hr. and hydrogen to hydrocarbon mol. ratio of 5-25:1 over a desulphurization catalyst, e.g. cobalt molybdate or molybdenum disulphide on aluminia, subjecting the product to a hydrocracking step in a second hydrocracker to effect dealkylation either thermally at 1100-1800 DEG  F., 50-2500 p.s.i.g., 2-300 seconds and hydrogen to hydrocarbon mol. ratio of 3-25:1 or catalytically at 900-1200 DEG  F., 150-1000 p.s.i.g., hydrogen to hydrocarbon mol. ratio of 5-25:1 and 0.2-5.0 vol./vol./hr., recovering benzene and naphthalene and recycling at least part of the unconverted alkylbenzenes to the second hydrocracker. Preferably gas and a C5-400 DEG  F. gasoline cut are removed by fractionation from the first hydrocracker effluent and the remainder passed to the second hydrocracker direct or through an intermediate catalytic cracking zone operated in the absence of hydrogen at 100-1000 DEG F., 0-1000 p.s.i.g., in liquid or gaseous phase with a contact time of 2 seconds-5 hours in the presence of silica-alumina, activated clays, supported boron trifluoride-hydrogen fluoride or a Friedel-Crafts metal halide. Preferably such cracking is effected in the presence of recycled benzene and alkylnaphthalenes to effect transalkylation between benzene and alkyl-naphthalenes. Alkyl-benzene recycle is then added before the second hydrocracker. Suitable catalysts, if used, for the second hydrocracker are the desulphurization catalysts specified for the first hydrocracker and optionally supported chromia or molybdena.

Title: Predictive gauge control method and apparatus with automatic plasticity determination for metal rolling mills
IPC: B21B37/16
Filed: 1969-01-31
Abstract: 1,262,742. Automatic control systems. WESTINGHOUSE ELECTRIC CORP. Jan.31, 1969 [Feb. 2, 1968], No. 5326/69. Heading G3R. A gauge control system for a rolling mill having at least one stand comprises means for adjusting the screwdown by an amount which is predictively determined from the stand spring constant, the plasticity of the material being worked (hot steel strip) which is determined "on line", and the gauge error which in turn is determined from measurements of the roll force and the unloaded roll opening and reference values for these quantities. A prior art system (Spec No 1248978) is discussed in which gauge error and the necessary screwdown correction is determined from measurements of the rolls gap and load force, due allowance being made for mill "spring" and workpiece plasticity, values for which are derived from tables. In the present invention the plasticity is determined "on line", by dividing the load force by the reduction in thickness through the stand. In general, in a multistand mill, the thickness at entry and exit at any stand N is determined from the screwdown position, the force and the spring constant of the stands N-1 and N respectively, but the final thickness is measured by an X-ray gauge 42. In using the values for stand N-1 allowance is made for the transport time between N-1 and N. For the first stand or in a single stand reversing mill entry gauge is measured. Compensation may be provided during acceleration and deceleration by adding a screwdown correcting term equal to a constant times the difference between the instantaneous and the initial speed. Allowance (unspecified) can be made for the elasticity of the workpiece. Alternatively the thickness at exit and entry of any stand may be derived from a find thickness measurement and speed measurements (mass flow technique). In the multistand mill shown, each screwdown position is determined by a digital computer 38 using three terms, (i) a proportional plus integral term from the X-ray gauge 42, the proportionality and integrating constants being different for each stand, (ii) compensating term for acceleration or deceleration, and (iii) the correcting term allowing for mill spring and wcrkpiece plasticity as derived above. A dead band is set for each stand so that small errors affect the last two or three stands only. The calculation is performed at intervals, at a selected rate. The screwdown control is rendered inoperative if a number of conditions are not met, or if the calculated correction is outside limits. Each screwdown is operated by a servo motor 28 with a closed loop control having rate feedback provided by a tachogenerator 29. Tension may be controlled by "loop detectors" L which adjust the speed of each stand and the screwdown correcting signals are fed to these systems to enable them to anticipate the resulting charge of speed.

Abstract: 693,463. Converting. BRITISH ELECTRICAL & ALLIED INDUSTRIES RESEARCH ASSOCIATION. Feb. 28, 1952 [March 6, 1951], No. 5422/51. Class 38 (ii). An uncontrolled, unidirectionally conducting by-pass such as the mercury vapour tube 50 with its grid connected to the cathode through resistance 51, is connected between a D.C. line 16 and the earthed centre point 19 on the side of the smoothing inductance 40 remote from rectifying equipment supplying the line from A.C. supply 11. Thus, when under fault conditions the rectifiers are interrupted by grid blocking and the polarity of the D.C. line reverses from the effect of the smoothing inductances associated with inverting equipment at the distant end of the line, this reverse voltage is reduced by current flow through the by-pass. The rectifying equipment may comprise two sets of mercury-vapour-converters 1-6, each set being connected in double threephase bridge arrangement between the centre earthed point and one line. One set only is shown connected to line 16. The unidirectional conductor in the by-pass may be an electrolytic rectifier, and, especially if the D.C. line is short, it may be in series with a dissipating resistance 52.
