Title: A process and an apparatus for the manufacture of finely distributed or colloidal mixtures of bodies insoluble in one another
IPC: B01J13/00
Filed: 1928-03-03
Abstract: 286,316. Polanyi, M., and Bogdandy, S. von. March 4, 1927, [Convention date]. Emulsions, making.-Fine distributed mixtures of substances insoluble in one another are obtained by vaporizing or cathodically atomizing one substance, e.g. a metal, and condensing it in a vacuum on the surface of a liquid body of the other substance. The liquid is preferably continuously circulated at a high speed. A suitable apparatus comprises an evacuated container 1 for the liquid within which an inner vessel 13 is rapidly rotated. The liquid is drawn into the inner vessel by centrifugal force through radial passages 29 in the bottom thereof and escapes at the upper end by passages 36. The size of the passages can be adjusted by means of screws 34, 37 respectively. A rim 35 at the top of the vessel 13 ensures the retention of a liquid layer of appreciable thickness. The vapour of the substance to be dispersed enters the apparatus by a pipe 7 heated to prevent premature condensation and surrounded by a heat-insulating layer to prevent communication of heat to the liquid, The outer vessel 1 is cooled by means of a jacket 3. A comb-like device 42 causes eddies on the surface of the liquid in the rotating vessel to facilitate the mixing of the liquid and the condensate. Specification 269,586 is referred to.

Abstract: 684,569. Magnetic recording apparatus. BRITISH CELANESE, Ltd. March 19, 1951 [March 20, 1950], No. 6886/50. Class 40 (ii). In an apparatus for recording sound on an endless band in the form of a hollow coil 10 with a loop 11 of the band extending from the innermost convolution to the outer convolution, a plurality of supporting rollers 6, 7, 8, 9 are embraced by the coil, and a recording roller 12, a drive roller 14 and a pad roller lie within a zone encompassed by the coil and arranged so that the portion of the loop passing over the said rollers assumes a position in which its edges are in the same planes as the edges of the coil 10, means being provided to rotate the said drive roller 14 at a uniform speed. In the embodiment described, a magnetic recording system is employed in which a number of parallel tracks are recorded, the recording head 38 and erazing head 39 being mounted on a carriage 44 which is made to traverse the width of the loop 11 by a leadscrew under the manual control of a handle 48 having a pointer to indicate on the dial 49 the transverse position of the heads. The heads 38, 39 are pivotally mounted at points 41 on the carriage 44 and have arms 69 connected by springs 45 to arms 46 on the carriage 44 whereby the heads 38, 39 are pressed against the recording roller 12. The drive roller 14 is mounted on a shaft 30 carrying a heavy flywheel 31 which is belt driven by a motor 34. The pad roller 15, which is mounted on an arm 57 on a shaft 60, presses against the drive roller 14 through the medium of a spring 61 connected to a lever 59 mounted on the shaft 60. Removal of the coil from the machine is facilitated by the operation. of a lever 56 having an arm 62 which, when moved counterclockwise, as viewed in Fig. 2, presses on the arm 63 of lever 59 so that the pad roller 15 is moved away from the drive roller 14. At the same time a rod 64 connecting arm 63 to an arm 65 on a shaft 66, rotates the shaft 66, presses the arms 69 on the heads 38, 39 upwards and withdraws the heads 38, 39 from the recording roller 12. The roller 6 has a large flange 24, similar to that on roller 8, and is mounted on an arm 50 on a spindle 51 which is held in the operative position by means of pins 52 extending into a boss 53 in the panel and by means of a spring (not shown) beneath the panel. A knob 54 enables the roller 6 and arm 50 to be pulled out against the action of the spring, so that the arm can be swung downwards to facilitate removal and replacement of the coil 10. The loop 11 is guided back to the outer part of the coil 10 by means of a guide 17 and a frusto-conical roller 18.

Abstract: 560,140. Thermionic valves. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING AKT.-GES. May 26, 1942, No. 7126. Convention date, May 23, 1941. [Class 39 (i)] The cathode and and grid of a demountable transmitting tube comprise parallel wires or rods which are relatively rotatable about the tube axis while under vacuum, so that the grid current characteristic can be adjusted during use. The cathode K, Fig. 3a, may comprise four groups of three filaments and the grid G may have its four wires either between the groups as shown or opposite the centre member of each group. In the first position the grid secondary emission is greater owing to the absence of space charge near it and to the obliqueness of incidence of primary electrons, and the grid current will assume negative values, while in the second position the current is always positive. If the cathode comprises a number of evenly spaced filaments a smaller rotation is necessary to bring the grid from the position between the filaments to that opposite a filament, Fig. 4b; in this case the number of filaments is an integral multiple of the number of grid rods, but this need not be so. Where helical grids are used the supports are treated as the grid rods. The relative rotation is performed after warming the cathode seal to render it plastic. Push-pull valves may be matched while in operation.
