Patent GB-956247-A (GB)
Title: Improvements in or relating to the manufacture of cellulose ethers
IPC: C08B11/08
Filed: 1961-04-07
Abstract: Cellulose is hydroxyalkylated in presence of an alkali and water to MS 0.05-0.8, the alkali/cellulose and water/cellulose ratios being 0.2/1-0.8/1 and 0.8/1-4.0/1 respectively, and after removal of substantially all the remaining alkali and other impurities e.g. salts, the etherification of the partially hydroxyalkylated and purified cellulose is continued in presence of alkali using an alkali/hydroxyalkyl cellulose ratio of 0.005/1-0.1/1 to an MS of at least 1.0.  Preferably all the alkali is removed e.g. by neutralization at the end of the first stage, and fresh alkali added for the second stage, but sufficient alkali for the second stage may be retained from the first stage. Suitable alkalis are alkali metal hydroxides and organic bases e.g. trimethyl benzyl ammonium hydroxide, dimethyl dibenzyl ammonium hydroxide and tetramethyl ammonium hydroxide.  The process may be applied to the formation of e.g. hydroxyethyl, hydroxypropyl and hydroxybutyl cellulose using such etherification agents as ethylene oxide, propylene oxide, and 3, 4-epoxy-1-butene.  A water-miscible, inert organic liquid may be used as a diluent.  In an example, a mixture of cotton linters, water, sodium hydroxide, and tertiary butanol is heated with ethylene oxide for 4.5 hours at 50-60 DEG C. After neutralization of the alkali with propionic acid, the hydroxyethyl cellulose (MS 0.43) is washed with aqueous methanol, dried and then further hydroxyalkylated. Specification 688,486 is referred to.

Title: Image tubes
IPC: H01J29/41
Filed: 1962-04-02
Abstract: 977,428. Image converter tubes; cathode materials and processing. WESTINGHOUSE ELECTRIC CORPORATION. April 2, 1962 [April 28, 1961], No. 12587/62. Heading H1D. In an electron discharge tube utilizing a charge image formed on a target, e.g. an image converter tube with at least one secondary electron emissive member between the input photocathode and the output phosphor screen the secondary electron emissive member comprises a thin continuous conductive (e.g. aluminium) layer 32 transmissive to the primary electrons and a secondary electron emissive insulating layer 36 (e.g. barium fluoride, potassium chloride or magnesium oxide) which has the property of providing a greater contrast over its surface between light and dark areas than existing in corresponding parts of the bombarding electron image and, further, the property that such contrast increases with time. An intervening aluminium oxide layer 34 may or may not be provided. A spongy or porous barium fluoride layer 36 is formed by evaporating the material from a tungsten boat at a distance of 3 inches in an argon atmosphere under 1 mm. Hg. In operation a positive grid opposite the layer 36 limits the potential to which the surface can rise. Storage properties of the layer 36 may be utilized, the radiation image source being removed after formation of the change pattern and the change pattern being utilized to modulate the flood beam produced by a subsequently applied uniform radiation image. The stored pattern may be erased (1) by bombardment with primary electrons which penetrate right through the layer 36 and are directed back into the surface by a negative electrode; (2) by heating; or (3) by reducing the velocity of the primary electrons to provide a secondary electron yield less than unity. A focusing magnet around the tube is provided by a tubular permanent magnet. Other types of discharge tube in which a flying spot scanner modulated with image information is utilized to excite the cathode or in which a scanning electron beam modulated with the image information is utilized are referred to. The tube may be of the direct viewing type. A flying spot scanner may be used in the reading operation and the information may be read out as electrical signals instead of as a visible output. Specifications 792,507 and 862,211 are referred to. Reference has been directed by the Comptroller to Specification 911,560.

Title: Improved method of and apparatus for film-drying glue
Inventor: ZEIGLER ALBERT HOWARD
IPC: C09H9/02
Filed: 1951-06-06
Abstract: <PICT:0707412/III/1> In the drum-drying of animal and vegetable glues, the film scraped off the drum passes through a pair of chilling rollers rotating at a slower peripheral speed than the drum whereby the film is crinkled as it leaves the drum.  The crinkling prevents adherence of the glue film to the conveyer in a subsequent drying operation. Glue solution from a heated reservoir 20 is fed to a container 14 the overflow from which is recycled to the reservoir 20.  From container 14 glue is fed on to a steam-heated drum 10 by an adjustably mounted feed roller 15 which may be steam-heated or water-cooled.  The glue-film is maintained on the durm 10 by compressed air from a pipe 27 directed by a baffle 29 and by compressed air from a pair of blowers 30.  It is removed from the drum by a knife 31 which has steam directed against its edge from a pipe 34.  Compressed air is directed against the outside surface of the film by pipes 37 and 38 to produce surface-hardening.  The film now passes between chilling rollers 41 and 42 rotating at a slower peripheral speed than the drum 10 and which are respectively chromium-plated and of steel, the roller 42 being the cooler.  The glue sticks to roller 42, is removed by a knife 43 and passes on an endless conveyer 45 through an apron drier comprising three compartments heated to progressively higher temperatures.  At the outlet of compartment 49 the film is given a final surface-hardening by a fan 55 and then comminuted.
