C. ; Edgewater Park, both in New Jersey, U.S.A.) May 11, 1932, No. 13623. Convention date, June 30, 1931. [Class 39 (i).] Parts of the structure of cathode-ray tubes are made non-reflective to light emitted by other parts during the operation of the tube. In a sealed glass tube with an " electron gun " 12 producing the cathode-ray 13, with a rayfocusing anode constituted by a silver coating 15 on the wall 10 and with a fluorescent screen 11, the gun 12 and wall 10 with its coating 15 are made non-reflective to light from the screen 11. The contrast between light and dark parts of a television image on the screen 11 is thus increased by the elimination of the luminous background normally produced by reflected light. The coating 15 and the gun 12 may be coated with carbon using a water colloidal solution and evacuating the tube at 500‹ C. Alternatively, the silver coating may be coated with a black layer of silver sulphide or selenide by treatment with hydrogen sulphide or selenide gas or with a solution of selenium in carbon disulphide. Tellurium may replace the selenium ; silver telluride may also be formed by treating the silver with tellurium vapour.

Title: Improvements in can seaming mechanisms
IPC: B21D51/32
Filed: 1949-05-25
Abstract: 658,052. Seaming. BOULIGNY Inc., R. H. May 25, 1949, No. 14028. Convention date, June 29, 1948. [Class 83 (iv)] A can seaming machine comprises can supporting means adapted to be rotated by a drive-shaft, a seaming roll carried at each end of a cross-head mounted for transverse rectilinear reciprocation in the machine frame and means actuated by the drive-shaft for reciprocating the cross-head diametrically with respect to the can body to apply the seaming rolls successively to the work, the connection between the driveshaft and cross-head being such that the force of application through the cross-head is directly opposed to the reaction force at the rolls. The can body 11 with its lid 12 is supported on a table 19 carried by a spindle 21 rotatably mounted within a sleeve 22 which is supported within the machine frame by a tubular member 23 with an upper cam surface 24 engaged by a lug 25 projecting from the sleeve 22 so that by rotating the sleeve by a handle 26, the table may be raised to press the can body against a driving chuck 20. The chuck is secured to the end of a hexagonal shaft 33 driven by bevel-gears from a handle (not shown) and journalled in the top of the frame at 34 and in a plate 35 secured across the frame by bolts 36. Secured on the shaft for rotation therewith is a sleeve 37a with an eccentric flange 37 around which is an external gear 58, within and spaced from an internal gear 57 formed in a plate 56 secured to a cam 55 rotatably mounted on the sleeve 37a. The gear 58 is held against rotation by means of an arm 59 fixed to its upper surface and received in a slot 60 in the plate 35. As described, the gear 57 has twenty-one teeth and the gear 58 twenty teeth. On rotation of the shaft 33, the eccentric 37 and arm 59 cause the external gear to move in a circular path, without rotation, and thereby to rotate the gear 57 by one tooth for each complete revolution of the shaft, so that the cam 55 is driven at a greatly reduced speed compared with the chuck 20. Mounted in the frame for rectilinear movement beneath the cam 55 is a cross-head 13 having towards each end a series of holes 68, 69, 70 to receive studs 71 mounting the primary and secondary rolls 14, 15, appropriate holes being selected according to the size of the can. The cross-head is also formed with apertures to receive the bases 78 of eccentric pins 62 which comprise the followers of the cam 55. Arms 80 secured to the upper surfaces of the bases 78 and adjustable along arcuate slots 82 at the ends of the cross-head permit of accurate adjustment of the cam followers. As the cam 55 rotates, the cross-head is pushed first in one direction and then in the other so as to bring into operation the seaming roll on the opposite side of the shaft 33, thus balancing the forces at each side of the shaft.

Title: Process for making dihydrostreptomycin
Filed: 1951-06-13
Abstract: 694,829. Electrolytic production of dihydrostreptomycin. SCHENLEY INDUSTRIES, Inc. June 13, 1951 [Oct. 17, 1950], No. 14035/51. Class 41. Dihydrostreptomycin is produced by the electrolysis of a substantially neutral aqueous or aqueous alcoholic electrolyte containing dissolved streptomycin. It is preferred to use a non-homogeneous electrolyte and to restrict the streptomycin to the catholyte where reduction only occurs, the catholyte being separated from the anolyte by a semi-permeable membrane, thus reducing the tendency for the dihydrostreptomycin formed to decompose as it would at the anolyte. The catholyte is an aqueous or aqueous alcoholic solution of streptomycin e.g. as hydrochloride or sulphate, preferably containing a readily ionizable mineral acid salt, e.g. sodium sulphate or sodium bisulphate and having, or being adjusted to, a pH of 5-8.5; 5-25 per cent streptomycin is the optimum initial concentration. The anolyte is a good conducting electrolyte such as 20 per cent sulphuric acid, 1 per cent sodium sulphate, or an aqueous solution of zinc sulphate or sodium bisulphate. The cathode is a metal having a high hydrogen overvoltage, e.g. mercury or lead. Lead having a surface layer of spongy lead is preferred, the cathode being fluted to provide a large surface area. The anode is of small surface area, and may be formed of carbon, platinum, lead, argentiferous lead or antimonial lead (5-6 per cent antimony), which is preferred. The electrolytic cell may be of glass or ceramic material with a fritted glass or porous ceramic semi-permeable diaphragm separating the cathode and anode. Electrolysis is carried out below 55‹ C., and preferably at 25‹ to 30‹ C., although 10‹ C. may be employed. The electrolyte is cooled during electryolsis and the catholyte maintained at a pH of 5.0-8.5 by the periodic addition of mineral acid. Operating voltages are 15-30 volts with current densities of 0.1 to 0.01 amperes per sq. cm. of effective cathode surface. When reduction is complete (Maltol test), the pH of the catholyte is adjusted to 7 and filtered. The filtered solution is purified by treatment with ion-exchange resins and with activated carbon.
