Filed: 1947-02-19
Abstract: 674,022. High-frequency discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 19, 1947 [Aug. 13, 1942], No. 4859/47. Class 39 (i). [Also in Group XL (c)] Electron discharge apparatus comprises means for transmitting electromagnetic waves through a rectangular pipe wave-guide 1, Fig. 2, means for firing an electron beam down the guide, the beam being focused by a magnetic coil 40, and means for modulating the density of the beam so as to vary the effective dielectric constant of the medium within the guide and hence to cause frequency, amplitude, or phase modulation of the waves. The beam density is varied by applying modulating potentials to an additional grid (not shown) between cathode 28 and control grid 27. The waves are led in via coaxial line 35, 36 and extracted via coaxial line 38, 39, the inner conductors 36, 39 being connected to the bottom of the guide and the outer conductors 35, 38 to the top of the guide. Seals 37 maintain the vacuum within the guide. The cathode 28 is indirectly heated and the grid 27 is formed in the end wall 26 of the guide. The guide is sealed to a glass press 33 via tapered metal member 34. The waves in the guide may be E or H waves, e.g. an H 01  wave. Wave reflections from end wall 25 may be prevented by prolonging the guide one-quarter wavelength and mounting an anode on a resistive plate one quarter wavelength from the end. The end wall is connected to the anode by an axial lead. The Specification as open to inspection under Sect. 91, refers to the use of charged particles generally and states that the guide may be filled with a " medium " at any desired pressure. A nickel-iron-cobalt seal may be utilized between members 33, 34. The density control of the beam may be effected by variation of the potential of the anode or of an additional grid placed inside the guide. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the production of methyl glycerol
IPC: C07C31/22
Filed: 1940-03-18
Abstract: 535,986. Methylglycerol. DISTILLERS CO., Ltd., STAUDINGER, J. J. P., and TUERCK, K. H. W. March 18, 1940, No. 5038. [Class 2 (iii)] Methylglycerol is made by oxidizing crotonaldehyde directly in a non-alkaline medium to methylglyceraldehyde which is then hydrogenated catalytically to methylglycerol. Alternatively the crotonaldehyde may be oxidized indirectly by chlorine-water or hypochlorous acid to α-chloro-#-hydroxy butylaldehyde which on hydrolysis with weakly-alkaline or neutral agents yields methylglyceraldehyde which is then hydrogenated as before. The direct oxidation may be effected with osmic acid and alkali chlorate at 25‹C. or 35‹C., the product being extracted as an alcohol solution, which is hydrogenated. In another method the crotonaldehyde may be oxidized with oxygen below 40‹C., preferably with a catalyst such as osmic acid, vanadic oxide, chromic acid or molybdic acid. In the indirect method the chloro-body may be hydrolyzed with sodium bi-carbonate, disodium phosphate, calcium carbonate or sodium acetate. The hydrogenation may be effected at 30-130‹C. for instance in the presence of nickel, platinum or palladium. In examples (1) aqueous crotonaldehyde is treated with chlorine, and the oily layer of α-chloro- #-hydroxy butyraldehyde is separated and agitated with sodium bi-carbonate, and the product extracted with alcohol and hydrogenated ; (2) crotonaldehyde is added to an aqueous solution of sodium chlorate containing a little osmic acid at 25‹C., the hydrogenation being effected with palladium.
