Filed: 1930-10-09
Abstract: 365,150. R÷ntgen ray apparatus. KOCH & STERZEL AKT.-GES., 40, Zwickauerstrasse, Dresden, Germany. Oct. 9, 1930, No. 30288. Convention date, Oct. 10, 1929. [Class 98 (i).] In apparatus of the kind in which the H.T. transformer and the ray-tube are enclosed in a common casing, the secondary coil of the transformer lies in an insulating body, the surface of which is enclosed in an earthed conductive coating, and the high potential conductor is carried out through insulating material passing through the earthed surface. As shown in Fig. 1, the iron core 12 of the transformer is supported by the casing 11 and carries the primary coil surrounded by two insulating reels 14, 15 in which are wound the two sections 16, 17 of the secondary coil, whose innermost and outermost windings have respectively the highest, and earth potential. The exposed surfaces of the reels are metallized, or metal-jacketed, and earthed. The high potential leads are brought out to. the ends of the ray-tube 22 through insulators 18, 19 which are integral with or fixed to the reels 14, 15, and surround at their ends the terminals of the tube. The reel 14 carries also a separate winding for heating the tube cathode. The ray-tube is mounted at its middle on a ring rotatable about the axis of the tube ; and the shape of the casing 11 and the electrical connections to the ends of the tube are such as to permit a rotation of the tube of more than 180‹. The ray-tube space has air-vents 24 and is cooled by a fan 25. In the modification shown in Fig. 5, the iron core 36 carries the primary coil 37 surrounded by an insulating carrier 38 on which are wound the two sections 39, 40 of the secondary coil, whose adjacent ends are connected together while their outer high-potential ends are carried out, through insulating extensions 41, 42 of the carrier 38 forming part of the walls of the casing, respectively to the ends of the ray-tube 22 and a valve tube 51 mounted on extensions 48, 52 of the insulators 41, 42. An insulating cylinder 45 having a conductive inner coating surrounds the windings 39, 40. The inner surface of the carrier 38 and the outer surface of the cylinder 45 are earthed as through a metallized coating or a metal jacket. Intermediate space is filled by a sealing mass 47. The heating transformer for the tube cathode is mounted on the extension 48, while that for the valve cathode is externally mounted. The conical earthed end of the raytube is carried by a threaded part 33 which affords access to the ray-tube and conducts heat therefrom. It may be provided with heatradiating fins 34. The cathode end of the valve is similarly supported. Ventilation is effected by a fan 53 forcing air into the valve space and core space, whence it passes through spiral channels in the wall 42 to the transformer windings 39, 40, thence through similar channels in the wall 41 into the ray-tube space, and is discharged through the closure member 33. In another modification, the construction resembles that of Fig. 5 without the valve tube and its casing.

Abstract: 1,110,724. Sampling granular materials; sampling liquids. MINERAIS ET METAUX. 6 July, 1966 [6 July, 1965], No. 30334/66. Heading B8N. A process for sampling batches of solid and/or liquid material, which material varies in a substantially cyclic manner, comprises sampling the material at intervals which are irregular in a random manner but have a predetermined average value. The irregular intervals are obtained by modifying each of a series of equal intervals, e.g. 10 minutes, by values, e.g. 2 minutes, 3 minutes, corresponding to numbers taken at random, each of the values being less than the value of a said equal interval. As described, when applied to samples taken during a working shift of an ore-washing plant, a timer is used to control operation of the sampling apparatus. The timer may include a disc rotated by a synchronous motor, with indicia provided on the disc, e.g. conducting marks, magnetic marks, perforations, or a drum or magnetic tape may be used with appropriate reading means.

Title: Marking of x-ray films
IPC: G03B42/04
Filed: 1961-08-28
Abstract: 937,155. Marking films. GEVAERT PHOTOPRODUCTEN N.V. Aug. 28, 1961 [Sept. 5, 1960], No. 30910/61. Classes 98 (1) and 98 (2). X-ray films are marked in bulk (i.e. a large number of sheets simultaneously) by exposing them as a pack to a source of radiation separated from them by a radio-opaque screen; the screen has a cut-out pattern, which may be letters or other markings, so that this pattern appears on all the sheets. The radiation source may be an X-ray tube, or radioactive material. The drawing shows a device for carrying out the process. The X-ray films are carried in boxes 5 on an endless belt 7. The X-ray beam 1 is shielded by a conical lead tube 2, with a base 3 which is provided with the cut-out letters or markings. As a box 5 passes underneath the base 3, its progress is arrested by a bar 4, and thus it receives a predetermined amount of radiation. A lead plate 6 is fitted underneath the belt at this point. The bar 4 is then removed, so that the next box of films can be brought into position. Swiss Specification 286,526 is referred to.

Title: Separation of solutes by continuous solvent extraction
Inventor: JOHNSON JOHN DOBNEY ANDREW
IPC: C07C51/48
Filed: 1948-11-29
Abstract: Comprises a batch-fed process for the separation of solutes by continuous physical redistribution between solvents, in which a definite quantity of a mixture of the solutes is introduced into a plant comprising a series of mixing and separating units having the separators of much smaller capacity than the mixers, and two solvents which are immiscible or partly immiscible with each other are caused to flow in opposite directions through the units.  The separators may be of the gravity, centrifugal, or other type. Three arrangements of plant are described.  In the arrangement shown in Fig. 1, solvents A and B are introduced respectively into the end mixers Mn and M1 of <PICT:0663876/IV (b)/1> <PICT:0663876/IV (b)/2> the series and are withdrawn from the end separators S1 and Sn; in the arrangement shown in Fig. 2, the units are arranged in a closed system and contain fixed quantities of the two solvents which are caused to travel in opposite directions round the series of mixers and separators; in the third arrangement, shown in Fig. 3, one solvent is caused to flow through the plant while the other is returned from any given separator to its corresponding mixer, so that the second solvent remains in the apparatus without moving from end to end thereof.  The solutes become distributed in the two solvents according to their respective distribution coefficients and are either drawn off continuously in these ratios in the arrangement shown in Fig. 1, or one is continually drawn off while the other remains in the plant which is stopped after a certain time in the arrangement shown in Fig. 3, or both or all the solutes become distributed in accordance with these coefficients in the various vessels shown in Fig. 2 and the plant is stopped at an appropriate time to collect the liquid from each vessel.  In examples: (1) a mixture of oxalic and succinic acids was placed in the 10th vessel of a series of 19 vessels arranged as in Fig. 1, and n-butanol saturated with water and water saturated with n-butanol were used as the solvents.  Succinic acid 82 per cent pure and oxalic acid 99 per cent pure were obtained; (2) a casein hydrolysate freed as far as possible from glutamic acid by other means was subjected to the same solvents as used in example 1 in an apparatus such as shown in Fig. 2.  Unwanted amino acids and other material were largely removed from vessels 1, 2 and 3 permitting the isolation of a further 10 per cent of the glutamic acid.
