Title: Process for xanthating alkali cellulose
IPC: D01F2/08
Filed: 1955-11-23
Abstract: Alkali cellulose is xanthated in a stationary vessel provided with a stirrer mechanism by evacuating the vessel, introducing nitrogen and/or carbon disulphide until the pressure inside the vessel is restored to atmospheric, spraying carbon disulphide into the vessel and simultaneously introducing alkali cellulose crumbs continuously, the delivery of carbon disulphide and of alkali cellulose to the vessel being carried out in such a way that the introduction of the two reactants is completed at the same time and all particles of the alkali cellulose come into contact with the carbon disulphide as soon as possible after entering the vessel.  In the example a vertical cylindrical vessel is evacuated through a vacuum pipe, a sliding-plate valve between the vessel and a gravity feed hopper being closed.  The pressure inside the vessel is then restored to atmospheric by introducing nitrogen and a small amount of carbon disulphide.  The sliding-plate valve is then opened and alkali cellulose crumbs are introduced via the gravity feed hopper, between which and the plate valve is a rotary segmental hopper (segmentally compartmented feed drum), in constant flow into the vessel.  At the same time the amount of carbon disulphide necessary for xanthation is introduced through ring sprayers, the introduction of both reactants being completed in 14 minutes, after which the plate valve is closed. The mixture is slowly stirred by means of a vertical-shaft mechanical stirrer and xanthation is completed in 40 minutes at 32-33 DEG  C. Dilute aqueous caustic soda solution for dissolving the xanthate is finally introduced through another ring sprayer coaxial with the stirrer shaft.

Title: Improvements in and relating to cutting and delivery apparatus for all-size printingmachines
IPC: B41F13/54
Filed: 1934-11-23
Abstract: 447,769. Delivery apparatus for printing-machines. QUICK, C. G., TURRALL, G., and BENNISON, W. E., 109, Borough Road, London. Nov. 23, 1934, No. 33762. [Class 100 (i)] In delivery mechanism for " all - size " printing - machines two members are provided, of which at least one comprises an endless flexible member driven at the variable speed of the web and having part of its run extending a substantial distance between the severing and folding mechanisms, and which are arranged to co-operate with each other to receive a sheet from the severing-mechanism and to grip and propel the sheet towards the folding-mechanism, and means is provided whereby the extent of cooperation between the two members can be so varied as to enable sheets of different lengths to be released by the members as they are taken by the folding -mechanism. In the arrangement shown, the cutting-cylinders 1, 2 rotate at an angular speed which is constant with reference to the angular speed of the printing-cylinders, the cutting-speed being equal to the mean of the various web speeds : alternatively, the cutting- cylinders can be operated so that they are speeded up to speed of the web during the cutting operation. The cylinders 5, 6 are part of a folding-mechanism, are fixed relatively to the cylinders 1, 2 at a distance which is greater than the length of the longest sheet to be produced, and are driven at an angular speed which is constant with reference to that of the printing- cylinders, their peripheral speeds being equal to or slightly greater than the maximum web speed. The sheets cut by the cylinders 1, 2 pass between a pair of endless belts 7, 7<1> to the cylinders 5, 6, these belts being supported on fixed pulleys 8, 9, and 10, and jockey pulleys 11, and driven at a speed which is equal to or greater than the speed of the web. Pulleys 13 mounted in a fixed position between the pulleys 8, 9, are adapted to press the vertical runs 12 of the belts together to grip a sheet to propel it towards the cylinders 5, 6. One of the pulleys 13 is mounted to be oscillated against the action of a spring 191 towards the other pulley by means of a system of levers actuated from a two-part adjustable cam mounted on the shaft of the cylinder 5. The arrangement is such that for any particular size of sheet the movable pulley 13 will be pressed against the other pulley 13 until or just before the leading end of the sheet is taken by the cylinders 5, 6, whereby the sheet can be accelerated by the cylinders 5, 6. More than one set of belts may be used, and these may be adjustable transversely of the sheet path. In a modification, the two'pulleys 13 are spring-pressed towards one another, and are mounted in slides which can be adjusted towards or away from the cylinders 5, 6 according to the length of sheet, whereby when the cylinders 5, 6 take the leading end of the sheet the trailing end of the latter is not gripped by the belt.
