Abstract: 449,127. Thermionic valves. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Sept. 13, 1935, No. 25461. Convention date, Sept. 13, 1934. [Class 39 (i)] A method of gettering an evacuated ther mionic discharge device comprising a metal envelope con taining an electrode and a getter positionec within the envelope either directly upon or near to the wall there of, consists in heating the envelope at a localized position or the exterior wall of the envelope opposite the getter and causing a portion of the heat to reach the getter by conduction through the envelope to flash the getter. In the rectifier shown, a magnesium strip 13 is welded to the interior of the envelope 1 which may be of iron, tin or nickel. The directly-heated cathode 8 comprises loops of coated nickel strip. The header member 3 carries cathode conductor seals 4 of the kind disclosed in Specification 179,779, [Class 36], and the metal evacuating tube 9 sealed as in Specification 449,126, and is welded to a flanged portion of the envelope. The getter may be contained in a pocket or dent in the envelope and baffles or shields may prevent deposition of getter material in undesired parts, as described in Specification 443,767. Alternatively, the getter may be contained in a capsule supported on a rigid wire close to or touching the envelope so as to receive heat therefrom. The method may be applied to devices containing gas or vapour, such as argon or mercury, and to electrostatically or magnetically controlled thermionic arc discharge devices.

Title: Selective extraction of hydrocolloid fractions
IPC: C08B37/00
Filed: 1962-07-04
Abstract: In a process for treating solid undissolved carrageenan - containing material comprising lambda and kappa components for the selective extraction of the lambda component therefrom, the material is soaked in an aqueous solution of a water-soluble salt or hydroxide of ammonium, potassium, rubidium, caesium, calcium, barium, strontium or magnesium at a temperature not less than 5 DEG  C. and not more than 90 DEG  C., the cation concentration at such temperature being within the range effectively equivalent to potassium as defined in the relationship o > log c > 0.03T - 2.77, where c is the potassium ion concentration in moles per litre and T is the temperature of the solution in  DEG  C., the lambda component of said carrageenan-containing material under the combined conditions of cation concentration and temperature being rendered substantially more soluble than the kappa component so as to go into solution in substantial amount while the kappa component is selectively prevented from going into solution, and separating the solution containing dissolved lambda component from the undissolved residue containing the kappa component. The carrageenan-containing material may be a sea-plant of the order gigartinales. Extraction of the lambda-carrageenan may be facilitated by providing hydroxyl ions, e.g. 0.025-0.2 moles per litre, in the extraction solution to increase swelling of the sea-plant. The cation of the hydroxyl-supplying compound may be one of those specified for the extraction, provided its concentration in the solution is compatible with the concentration limits defined for the extraction, or specified compounds are hydroxides of sodium, potassium calcium and ammonium, quaternary ammonium hydroxides, and sodium and potassium carbonates, phosphates and borates.

Title: Improvements in and relating to controllers for electric motors
IPC: H02P7/18
Filed: 1919-10-21
Abstract: 158,045. British Thomson - Houston Co., Ltd., (General Electric Co.). Oct. 21, 1919. Rotary and oscillating disc valves.-Pneumatic operating means for electric motor controllers comprises a circular valve 45, Fig. 1, the function of which is diagramatically shown in Fig. 4, mounted on a prolongation of the driven shaft 2. The valve comprises three channels 31, 34, 36 shaped as circular arcs of 120‹, and corresponding ports through which, in succession, air is admitted under pressure, pressure is maintained, and air is connected to exhaust. Simultaneously with the changing over of the air ways at the circular valve, the movement of the shaft, by means of a cam and switch lever, breaks the circuit of a magnet B actuating slide valves which control the admission of air from a pressure reservoir into cylinders 5, 6, 7 and its escape to an exhaust. The next to and fro movement of the master controller thus causes the second cylinder to act in the same manner as the first, and the third subsequent to the second. Reverse action is obtained, when required, by shifting the master controller to the off position, thus disengaging a magnet A, and interchanging the functions of the channels 31 and 34.

Title: Improvements in the production of cellulose ethers
Inventor: DOWNING JOHN
IPC: C08B11/193
Filed: 1948-10-07
Abstract: A water-soluble cellulose ether is obtained by subjecting p cellulose in the presence of an alkali simultaneously to the action of sodium chloracetate or chloracetic acid and a methylating or ethylating agent, the proportions of the etherifying agents and the time of treatment being such that the product contains 0.75-1.3 methoxyl or ethoxyl groups and 0.1-0.5 carboxy-methoxyl groups for each anhydroglucose unit of the cellulose.  Alkali-cellulose may be impregnated with a concentrated aqueous solution of chloracetic acid or its sodium salt, and immediately or rapidly brought into contact with the alkylating agent, e.g. with vaporized or liquid methyl or ethyl chloride at 50-140 DEG  C., or the impregnated alkali-cellulose may be kneaded with dimethyl or diethyl sulphate at 20-50 DEG  C. Cellulose may be impregnated with a mixed aqueous solution of sodium chloracetate and sodium hydroxide, and then treated with the alkylating agent.  Cellulose may be kneaded with caustic soda, sodium chloracetate, and dimethyl or diethyl sulphate, with or without water, at 20-50 DEG  C.  Etherification may be carried out in presence of an ether-alcohol, e.g. the mono-methyl ether of ethylene glycol.  The cellulose ether obtained may be purified by washing it with alcohol, or it may simply be rendered neutral by adding hydrochloric acid or treating with carbon dioxide.  In an example, alkali-cellulose (1 mole.) is kneaded for 2.5 hours at 25-30 DEG  C. with chloracetic acid (0.5 mole.) and diethyl sulphate (0.75 mole.). After 16 hours, the product, which is almost completely soluble in water, is washed with ethanol. Specifications 462,456, 525,739 and 637,134, are referred to.  The Provisional Specification describes also the production of mixed ethers of cellulose in which the carboxy-methylation and the methylation treatments are carried out separately in either order.
