Patent SE-8405128-L (SE)
Inventor: BACKLUND A
IPC: D21D5/00
Filed: 1984-10-15
Abstract: Resin is removed from mechanical pulps, such as TMP, CTMP, and the like, in a quick and simple manner. Mechanical pulp at a consistency of about 7-20 percent (preferably 8-15 percent) is subjected to high turbulence. The high turbulence may be effected by fluidizing the pulp, as in a centrifugal fluidizing pump, or otherwise by subjecting it to high turbulence as in a mixer, screen, or disc mill refiner. By subjecting the pulp to high turbulence treatment for a time period of about 0.2-10 seconds, resin removal is greatly enhanced, and in subsequent dewatering of the pulp a pressate is formed which has a higher concentration of resin in the pressate than in pressates produced by conventional processes. After dewatering the pulp is preferably diluted (again to about 7-20 percent consistency), and the turbulence and dewatering steps are repeated. Chemicals to improve deresination can be added to the pulp while it is subjected to high turbulence.

Abstract: An improved method for treating cellulosic material recovered from a disc refiner in a mechanical pulp making process. Latency removal is conducted at a medium consistency of from about 8 to 15 percent in a medium consistency pump after which the suspension is removed at a medium consistency first to a screening device and then to a storage tank. Cleaning then takes place at low consistency. The method affords efficiencies in the nature of reduced capital costs and energy consumption.

Abstract: The safety gear is constituted by a sleeve 1 which is fitted to a chain drive 2 coaxially herewith. The tubular sleeve has diametrical recesses 3 in which a piston 4 is displaceable to and fro. It is nevertheless detained in the groove by means of a bolt 6 which is screwed into the piston. The chain drive 2 is fitted vertically so that when the pinion gear rotates upon movement of the lift, for example, the piston 4 joins in the rotation but falls throughout under gravitational effect to assume its lowermost position. This applies as long as the chain drive moves at a moderate speed. Should the speed be increased, then the centrifugal force acting upon the piston will detain this in its projecting position so that it hits against the stop 7 which is arranged over the chain drive. <IMAGE>

Abstract: Process for removing nitrogen oxides from the flue gases of a soda recovery boiler of a pulp mill. In the method, to the flue gases of the soda recovery boiler is at first fed an oxidizing agent, such as chlorine dioxide or ozone, which oxidizes nitrogen oxide to nitrogen dioxide. Subsequently, the flue gases are led into a flue gas scrubber, in which a reagent coming from the circulation of chemicals of the pulp mill is injected into the flue gases, which reagent brought into contact with the nitrogen dioxide reduces the nitrogen dioxide to nitrogen. The flue gas containing nitrogen is led out of the scrubber and the oxidized reagent is led back to the circulation of chemicals of the pulp mill.

Abstract: The invention relates to a method of producing reclosable absorbent garments, in particular absorbent pants, and to the absorbent garments obtainable by said method. Starting from a continuous web (1) of absorbent articles attached side-by-side and with a line of weakening (6) arranged between adjacent articles, a first strip (8) comprising releasably attachable material is applied across the line (6) at one edge (25) of the web. A second strip of flexible material is also applied across the line (6) at the other edge (26) of the web. The web is then folded longitudinally to form a series of closed, joined adjacent articles. The adjacent articles are then partially separated at said line (6) but without rupturing said strips (8, 13), so as to provide a free zone (15) between said strips (8, 13) and the adjacent separated edges of each article. The strips (8, 13) are then joined together across the free zone (15) to form a plurality of joined garments. The strips (8, 13) may then be severed so as to form individual garments (27) of the reclosable type, or may remain unsevered and be foreseen with a line of weakening for later separation. Due to the particular method and product features of the invention, an in-line process for making closed, reclosable absorbent garments is achieved.
