Patent GB-711669-A (GB)
Title: Cellulose esters
IPC: C08B15/10
Filed: 1952-06-06
Abstract: A cellulose derivative composition comprises a mixture of a cellulose ester containing radicals of crotonic acid and of another aliphatic carboxylic acid, with an unsaturated non-cellulosic ester of an a - b - unsaturated dicarboxylic acid with an alcohol containing more than one hydroxy group.  The mixture may be submitted to conditions favouring copolymerization of the cellulose ester and the non-cellulosic ester so as to obtain a cellulose derivative which is of reduced solubility or is insoluble in common organic solvents such as acetone, and which has a high melting point.  The cellulose crotonate and the unsaturated non-cellulosic ester may be dissolved in a mutual solvent and the solution may be converted into filaments, yarns, tow, ribbon, straw, foils, films, or other articles. Alternatively, a mixture of the cellulose ester and the other ester may be moulded or otherwise shaped in the absence of a solvent or in presence of a small proportion of solvent.  As a further alternative, the unsaturated non-cellulosic ester may be applied to a preformed article, e.g. a filament or fabric, of the cellulose crotonate by dipping, padding, spraying, or other method.  The cellulose crotonate admixed with the unsaturated non-cellulosic ester may then be heated at 60 DEG -200 DEG C. for 1-60 minutes, to cause co-polymerization with formation of cross-linkages between the cellulose molecules. The treatment may be effected in presence of a catalyst such as tert.-butyl perbenzoate, benzoyl peroxide, cumene hydroperoxide, tert.- butyl hydroperoxide, and di-tert.- butyl peroxide.  The unsaturated ester may be obtained from ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, 1.4- butanediol, or glycerol a - monochlorhydrin, and maleic, methyl maleic, chlormaleic, or fumaric acid or anhydride.  The unsaturated non-cellulosic ester may be used in monomeric form or in a condensed form, which may have a molar excess of the alcoholic component, and it may contain some groups of a saturated dicarboxylic acid such as succinic, adipic, or phthalic acid.  The cellulose crotonate may be cellulose acetate crotonate, propionate crotonate, or butyrate crotonate.  It may contain 0.05 to 1 crotonic acid ester group per glucose unit and 0.10 to 0.60 free hydroxyl group.  The compositions may contain plasticizers, pigments, and other additions.  In an example, a solution of cellulose acetate crotonate in a mixture of acetone and benzol is prepared, and to it is added diethylene glycol maleate and also a small proportion of tert. butyl perbenzoate.  The solution is cast to form a film which is dried and then heated at 150 DEG C.  The film is rendered insoluble in acetone and resistant to softening at temperatures up to 150 DEG C.  Specifications 609,790, and 674,993 are referred to.

Title: Improvements in and relating to cutting, counting, and marking sheets of paper, card and the like
IPC: G06M9/00
Filed: 1946-05-20
Abstract: 611,978. Delivering sheets. BATTERSBY, J. E., and MASSON, SCOTT & CO., Ltd. May 20, 1946, No. 15167. [Class 100(i)] [Also in Groups XIX and XL(b)] In a machine for cutting webs of paper into sheets and stacking the sheets, electrical mechanism is used to count the sheets and to actuate a feeding means for feeding a marker between the sheets after a predetermined number of sheets have been counted. The paper 3 is fed by rollers 1, 2; 5, 6, Fig. 3, to a cutter comprising a fixed blade 9 and rotating blade 10, which effects one cut for each rotation of a shaft 16, Fig. 2. A cam on shaft 16 closes a switch 17 at each revolution and thus operates the electrical counting mechanism, (see Group XIX), or the counter may be actuated under the control of a photoelectric cell actuated by the interruption of a beam of light by the passage of a severed sheet. When the required number of sheets have been cut, a switch 51 is closed and an electro-magnet is energized causing its core to operate a rod 91 which causes counter-clockwise movement of a lever 81 and thus brings a feed roll 83 into contact with a roller 96 which is driven continuously at a speed slightly greater than the speed of the web 3. The roll 83 receives marking material fed from a roll 67 mounted on a spool 68, and passing over rolls 74, 75 mounted on a lever 76. An adjustably mounted feed band 88 passes over the roll 83 and directs the web to rollers 86, 87, which direct the web to the cutters 9, 10. The roller 86 has a convex periphery and the roller 87 a concave one. As the roll 96 moves faster than the web 3, the sheet cut from it extends beyond the other cut sheets and so serves as a marker. The roll spool is normally held by a brake which is released at each energization of the electro-magnet which throws in the feed of the marking strip.

[Class 37] The current, voltage and power used by a resistance welding machine are measured with the aid of a short coil 6 arranged close to one of the conductors 2, 3 between the transformer 1 and the welding contacts 4, 5 near to the space between the conductors. When current is to be measured, the coil is connected to an ammeter. When the voltage drop across the welding joint is to be measured, the coil is connected in series with the voltmeter, Fig. 2 (not shown). In this case, the coil is rotated until the voltage induced therein counterbalances the voltage induced in the voltmeter leads. For the measurement of power, two such coils are used, Fig. 3 (not shown), one is connected to the current coil of the power meter and the other is connected in series with the pressure coil. In a modification, the meters are replaced by relays in order to control the quantities used. The coil may have an iron core.
