Title: Amylose derivatives and their production
IPC: C08B33/00
Filed: 1959-02-04
Abstract: Amylose ethers with a degree of substitution not exceeding 0,20 which are completely soluble in water of a temperature below 100 DEG C. are made by etherifying amylose in an alkaline aqueous solution to a degree of substitution not exceeding 0,20, neutralizing the reaction mixture by addition of an acid, adding before, during or after neutralization of the reaction mixture a salt which salts out the amylose ether or an aqueous solution of such a salt, in such an amount that the amylose ether precipitates, separating the precipitated amylose ether from the reaction mixture and washing it with water until it is substantially salt-free.  The amylose is preferably dissolved in an aqueous solution having a pH exceeding 13 and treated with an etherifying agent which contains no groups which are ionizable in water, e.g. dialkyl sulphates, alkylene oxides, alkylene chlorohydrins, styrene oxide and halogeno esters of aliphatic and araliphatic alcohols, such as chloromethane.  Suitable salts for the salting out step have a multivalent anion, such as sodium or ammonium sulphate or magnesium sulphate.  The amylose ether precipitate is preferably kept in an aqueous salt solution for the time required to render it completely insoluble in cold water, whereafter it is washed free of salt.  The amylose ether obtained can be rendered soluble in cold water by first dissolving it in hot water and then recovering it from the hot solution, for example by evaporation of the water.  Thus an aqueous dispersion of the amylose ether in cold water may be fed to heated rollers producing sheets of a solid product which is water-soluble.  An example describes the preparation of an amylose hydroxyethyl ether from amylose and ethylene oxide in aqueous caustic soda, the product being neutralized with sulphuric acid, salted out with magnesium sulphate and washed with water to remove salts.

The reaction is preferably carried out in an organic solvent, e.g. benzene, dioxane, toluene or xylene. Several examples are given and the products are useful for controlling pests and undesired plants (see Division A5).ALSO:Pests or undesired plants are controlled by contacting them with a pesticidal or phytotoxic amount respectively of at least one phosphorus compound having the general formula:-  (ClCH2)(Y)P(S)SZ wherein Y is a normal or iso-propoxy radical and Z is a naphthyl radical or a substituted aryl or substituted alkaryl radical, said substituents being halogen (e.g. Cl, Br or F) and/or nitro substituents (see Division C2). The phosphorus compound may be used above or in the form of an aqueous or non-aqueous solution, aqueous dispersion, wettable powder, vapour or dust.  The aqueous dispersion may be obtained by dissolving the active compound in acetone and diluting with water containing wetting agents.  When used as herbicides the active compound may be applied to the coil after planting but before emergence of the plants.

IPC: C13B10/06
Filed: 1921-02-05
Abstract: 172,552. Goold, R. L., (Fulton Ironworks Co.). Feb. 5, 1921. Roller mills.-In cane-crushing apparatus having rolls between which the cane is fed and each of the rolls having circumferential ribs separated by grooves, the pitch of the ribs on the lower roll is greater than that of the other roll so as to produce relatively wide channels or grooves for conducting the juice away from the rolls. As shown applied to a three-roll mill, the top roll D and the delivery roll C have the usual large number of small circumferential V-shaped ribs 1 and grooves 2, while the feed-roll B has relatively large V-shaped ribs 3 and grooves 4 forming large canals for the juice. Fig. 3 shows the large ribs 3 disposed opposite to and extending into alternate grooves 2 in the top roll D, which has intervening grooves opposite to, and in alignment with, the centres of the wider grooves 4.

Title: Improvements in or relating to electric discharge tubes
IPC: H03F1/54
Filed: 1930-02-07
Abstract: 348,120. Discharge apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and RAMSAY, H. T., of General Electric Co., Wembley, Middlesex. Feb. 7, 1930, No. 4262. [Class 39 (i).] In starting electric discharge tubes with a gas or vapour filling and with a thermionic cathode emitting sufficient electrons to avoid positive ion bombardment, delay in starting is produced, and destruction of the cathode by positive ion bombardment before its emission has risen is avoided, by means of a grid 4 shielding the cathode 2 from the anode 3, charged negatively with respect to the cathode when the voltage is first applied to the tube, and connected to the cathode through a condenser 9 shunted by a resistance 10. When the main switch 14 is closed, a switch 13 interlocked with the switch 14 is moved to the position a for a short time to charge the grid 4 negatively through a small, cold-cathode, gas-discharge rectifier 11, and is then moved into the position b. The negative charge leaks off the grid 4 over the resistance 9, the delay before the grid allows the discharge to start between the cathode 2 and anode 3 being such that the cathode has then reached a sufficient temperature. The tube 1 may be a rectifier, feeding a load 7 with a smoothing condenser 8, or may be a luminous discharge tube or a triode such as a thyratron.
