Title: Improvements in or relating to cellulose derivative coating compositions
IPC: C09D101/18
Filed: 1936-05-15
Abstract: A pigment for a cellulose derivative coating-composition consists of a titanate, for example, barium, zinc, lead, or calcium titanate. The pigments are of particular value in producing a light blue composition in which the blue component is iron blue.ALSO:Cellulose derivative coating - compositions which are resistant to chalking under atmospheric influences, contain as pigment a titanate, for example, barium, zinc, lead, or calcium titanate.  A number of examples are given of cellulose nitrate compositions containing barium titanate as pigment.  The pigments are of particular value in producing a light blue composition in which the blue component is iron blue.

Title: Improvements in electron discharge devices
IPC: H01J25/38
Filed: 1948-05-24
Abstract: 685,033. Travelling-wave tubes. NATIONAL RESEARCH DEVELOPMENT CORPORATION, May 24, 1948 [June 19, 1947], No. 13943/48. Class 39(i) [Also in Group XL(b)] A travelling wave tube employs a folded waveguide, Fig. 3, wherein only waves of a predetermined wavelength are amplified by interaction with the electron beam 14. This waveguide is stated to show positive dispersion. Two sections 61, 62, of the waveguide may be used to obtain an output isolated from the input, Fig. 7. The tube may be used as an oscillator with a feedback having a negative dispersion, Fig. 8 (not shown). In a modified arrangement, Fig. 9, requiring a feedback 87 with no dispersion, a hollow electrode 88 between two sections 80, 81 of folded waveguide, is biassed to determine the transit time between them. The potential applied to the electrode 88 is continuously variable in step with the beam voltage to maintain constant the total number of wavelengths corresponding to the transit time of the beam from 86 to 85. Alternatively, Fig. 10 (not shown), the transit time between waveguide sections may be controlled by a deflecting electrode, while Fig. 11 shows an arrangement wherein the beam retraces its path back to a collector 90, some of the electrons returning to the cathode 18, which may contain secondary emission material, so that the beam starts partially prebunched. Reflection at 93 is avoided by the use of "Aquadag " (Registered Trade Mark).

Title: Process for fractionating starch
IPC: C08B30/20
Filed: 1954-05-14
Abstract: The process for fractionating starch disclosed in the parent Specification is modified in that starch is dissolved under pressure at a temperature of at least 115 DEG C. e.g. 160 DEG C., in an aqueous solution of magnesium sulphate and/or sodium sulphate and/or ammonium sulphate, of such concentration that substantially no amylopectin can be precipitated by cooling the solution to any temperature above 10 DEG C., the solution is cooled until amylose alone precipitates, the amylose is separated from the mother liquor, the salt concentration of the latter is increased, e.g. by adding magnesium sulphate, until amylopectin precipitates without further cooling and the amylopectin is separated from the liquor. The starch may be dissolved in a solution containing between 25 and 30, e.g. 27, per cent by weight of magnesium sulphate heptahydrate, the resulting solution may be diluted with water to bring the salt concentration to a value between 18 and 25 per cent, preferably between 20 and 23 per cent, and then cooled to about 20 DEG C. to precipitate amylose. Amylopectin may be precipitated from the mother liquor by bringing its salt concentration to at least 25 per cent, preferably to a value between 26 and 28 per cent.
