Title: Improvements in analyzers operating by x-ray fluorescent radiation
IPC: G01N23/223
Filed: 1965-05-28
Abstract: 1,070,337. X-ray fluorescence analysis. E. LAURILA and M. O. LEIPONEN. May 28, 1965 [May 30, 1964], No. 22667/65. Heading G1A. In an X-ray fluorescence analyzer a test sample 21 and reference sample 22 are irradiated by an A. C. mains energized X-ray tube and fluorescent radiation therefrom is incident upon a detector 24 through a filter system 25. The filter system 25 comprises three sections, the outer ones (being of the same material) having a K absorption edge on the opposite side of the K emission line of the element being tested for from the central filter section. The filter system 25 is oscillated to and fro at half the mains frequency so that different filters are always in the sample and reference radiation paths. The output of detector 24 at half the mains frequency indicates the difference in concentration of the element tested for the reference and test samples; the sense of the difference being determined by a phase sensitive rectifier. The analyzer may operate in null mode by causing the output to vary the angle of the reference sample or an attenuator in the reference path. When Cu is to be detected the filters may be Co and Ni. Separate detectors may be used for the sample and reference radiation. In testing slurry for titanium, the slurry is homogenised and fed to a chamber 32, Fig. 3 (not shown) the bottom of which is a rotating wheel 33. A uniform layer of slurry is drawn with the wheel 33 for testing at 11, 16.

Patent GB-479940-A (GB)
Title: A process for the production of hydrocarbons
IPC: C07C9/00
Filed: 1936-08-19
Abstract: Hydrocarbons of gasoline boiling range are produced by heating a mixture of isobutene and one or more other tertiary olefines or secondary olefines (or a mixture of alcohols giving such a mixture on treatment with sulphuric acid) with about 64--72 per cent sulphuric acid at at least 60 DEG  C., e.g. 60 to about 250 DEG  C., for a time sufficient to effect substantial interpolymerization. Tertiary olefines specified are pentenes, e.g. trimethylethene, and hexenes. Secondary olefines include propene, butene-1 and -2, pentenes, and hexenes.  The olefine mixtures may be obtained by cracking petroleum, and, if desired, separating fractions containing the same number of carbon atoms, by destructive distillation or dehydrating alcohols. The less reactive olefines are preferably in molecular excess.  Thus, a C4 fraction is blended with a C3 fraction so that 1--1,5 mols. of secondary olefines are present per mol. of isobutene.  A mixture of C7 and C8 interpolymers is obtained on treatment under the defined conditions.  Excess of unreacted secondary olefines may be recycled. Pressure is preferably super-atmospheric.  The olefines may be absorbed in the acid prior to polymerizing or the acid may be at such a temperature that absorption and polymerization are simultaneous. The mixed alcohols may be treated with acid so that dehydration is followed by polymerization of the olefines formed, the acid having been diluted to the specified concentration.  The polymers may be hydrogenated, preferably in the liquid phase at elevated pressure. Pyrophoric nickel catalysts at about 150--300 DEG  C. may be used. In examples: (1) a mixture of tertiary and secondary butyl alcohols, water, and 95 per cent sulphuric acid is passed through a tube immersed in boiling water.  Average heating time is 20 mins. at about 99 DEG  C.  The concentration of the polymerizing acid amounts to about 64 per cent.  The product is largely dimers; (2) tertiary butyl and tertiary amyl alcohols are heated with 95 per cent acid at about 80--110 DEG  C. and 7--11 atmos., the acid after the dehydration being of about 72 per cent concentration.  The hydrocarbon layer is fractionated giving a mixture of nonenes which is hydrogenated at about 150 DEG  C. and 14--18 atmos.  The products are used as or as components of motor fuels and lubricating-oils, as solvents, and for the production of derivatives.  A sample has been furnished under Sect. 2 (5) of an octene fraction obtained by heating a liquefied butane-butene fraction at about 77 DEG  C. with 70 per cent H2SO4 for about 12 mins. This can be hydrogenated to an octane mixture of octane number 98--99.  The Specification as open to inspection under Sect. 91 is not limited to the use of acid of the specified concentration and refers to concentrated, e.g. 95 per cent, acid. This subject-matter does not appear in the Specification as accepted.

Patent GB-233030-A (GB)
Abstract: 233,030. British Arca Regulators, Ltd., and Lindsay, T. Jan. 29, 1924. Thermostats. - In processes in which live steam is used for effecting a chemical reaction such as for developing the colour of textiles, paper, &c., the moisture content of the steam is kept constant by circulation of the steam and by supplying automatically the amount of moisture required. Fig. 1 shows apparatus for carrying out the process. The material enters the chamber a through air-excluding flaps e and passes over a series of rollers. Live steam is introduced through a pipe f and, by injector action, withdraws steam from a pipe leading to the upper part of the chamber and forces it through a chamber k where it is supplied with water from jets r, and thence through a pipe l connected with a perforated pipe m in the chamber a. The moist steam from the mixing chamber k passes in contact with a bimetallic part 37 of a thermo-relay s of the kind described in Specification 206,154. The relay controls a regulating device of the kind described in Specifications 116,074, [Class 69 (ii), Hydraulic presses &c.], and 218,370, for the supply of water to the jets in accordance with the temperature of the steam. Instead of supplying moist steam, steam at any desired degree of superheat may be used.

Filed: 1948-09-06
Abstract: 645,397. Electric motors. SVENSKA AKTIEBOLAGET GAS - ACCUMULATOR. Sept. 6, 1948, No. 23394. Convention date, Sept. 5, 1947. [Class 35] [Also in Group XXXVII] A ring 26 of magnetic material is caused to tilt and operate contacts by the rotary or oscillatory movement of a shaft 2 carrying a magnet 31 which in addition to moving along over the ring 26 also flies outwards by centrifugal force thereby varying its magnetic effect. In the form shown, the ring 26 is fixed at 27, 28 to two arms of a four-armed plate 21, the other arms of which are fixed to the base 3 at 24, 25 and the plate 21 carries contacts 19, 20 adapted to engage fixed contacts 17 or 18 according to the direction of tilt of the plate. The magnet 31 as well as a similar non-magnetic member 32 are mounted pendulum-fashion on a U- shaped member 8 fixed to the shaft 2, so that when the shaft rotates, the passage of the magnet 31 over the ring 26 causes the periodical and alternate opening and closing of the two pairs of contacts 17, 19 and 18, 20. With greater speed, the magnet 31 flies outwards, the effect becomes less, and eventually the contacts remain permanently open. The shaft 2 may carry a magnet 7 influenced by two coils 9, 10 connected in circuit as shown in Fig. 2, so that the coils 9 and 10 are alternately energized and keep the shaft 2 in rotation. The device thus functions as a constant speed motor since rise of speed de-energizes the windings 9, 10. In a modification, adapted to operate as a frequency relay the coils 9, 10 are in series with an A.C. supply and so cause the oscillation of the shaft 2. In this case two torsion springs bias the blocks 31, 32 to a normal position above the two sets of contacts. The contacts below the magnet 31 will then be open and the opposite pair of contacts closed. Vibration due to A.C. will cause centrifugal action of the blades 31, 32 till eventually the closed pair of contacts will open.
