Title: A method of polysulphide treatment in alkaline pulping of lignocellulose material
IPC: D21C11/00
Filed: 1982-10-13
Granted: 1986-12-30
Abstract: Preparation of polysulphide for treatment of wood chips so that the wood consumption is reduced in kraft digestion of paper pulp. In an impregnation stage the wood chips are caused to react with black liquor, or black liquor components containing digestion liquor prepared of white liquor, while introducing oxygen of appropriate concentration in an impregnation vessel. The content of monosulphide, and to a certain extent other sulphur compounds present in the liquors, thereby forms polysulphide in contact with the wood chips which instantaneously absorb the polysulphide. Generation of polysulphide is promoted by wood reactions. Black liquor having a reduced concentration of hydroxide is withdrawn from the wood chips before delignification thereof in digestion liquor prepared of white liquor and residual impregnation liquor from the wood chips. The withdrawn black liquor is conveyed to a plant for regeneration of hydroxide in white liquor and sulphide, which wholly or partly is recovered in the form of white liquor, and which sulphide is repeatedly polysulphide-oxidized. The yield increment of pulp from the digester, as well as after the bleaching stage, is greater in oxidative polysulphide processing in presence of wood chips than in separate processing thereof in liquor before the charging into wood chips. This is interpreted such that more polysulphide is formed in the presence of chips than without.

Title: Method and apparatus for extruding a plastic pipe with controlled wall thickness
IPC: B29C48/395

Granted: 1988-07-27
Abstract: A pipe of thermoplastic polymer, e.g. polyvinylchloride is extruded.The wall thickness of the pipe is controlled in order to obtain a pipe of a substantially even wall thickness. For said control the wall thickness of the extruded pipe is measured at 360 points equally distributed over the circumference and moreover the average is determined in eight measuring sectors comprising 45 measuring points per sector. The average of the measuring values of one measuring sector is compared with the circumferential average of the 360 points, the deviation of the desired wall thickness in said one sector being counter balanced by the action of the heating elements.The apparatus of the invention for executing the method of extrusion of a pipe of thermoplastic polymer comprises an extruder with an extrusion die 2 having a moulding end part 2a and heating elements 11, 11' located about said end part 2a, and a wall thickness measuring device 7 being rotatably about the circumference of the pipe. The wall thickness measuring device 7 is transmitting measurement data to a signal processing unit 9. A comparator element 10 is provided for comparing two values of measurement values averaging operations and said comparator element 10 acts upon the temperature control device 8 controlling the temperature of the heating element 11 in a temperature control sector located in the axial extension of a measuring sector as compared with the average of the total circumference of the pipe.
