Abstract: A method for the production of kraft pulps in a digester, by modifying the cooking chemical concentration, and lignin concentrationprofiles during the cook, has provided extended delignification and improved selectivity in a simpler way than has previously been possible. The cooking is performed at an elevated temperature in two stages. The first stage liquor is a mixture of 1) the spent liquor of the second stage and 2) a portion of the conventional charge of fresh cooking chemicals needed for the complete cook. The second stage liquor is made up by adding an aqueous diluent, for example, fresh water or washing filtrate to the remaining portion of the fresh cooking chemicals.

Abstract: A  thermostatically  controlled  mixing  valve  having  a modular cartridge  mounted  in  a  housing.   The  cartridge comprises a tubular sleeve having rotatably disposed therein a hollow cylindrical housing.   The bottom of the cylindrical housing has  a volume control valve plate attached against rotational movement thereto.  The volume control valve plate cooperates with a fixed valve plate with which it is in surface-to-surface  contact  to control  the volume  of water flowing into the cartridge.  The fixed valve plate is affixed against rotational movement to a nose piece which is fixedly attached  to  the  bottom  of  the  tubular  sleeve.   An  inner housing is disposed within the hollow cylindrical housing and defines therewith cold and hot water inlet passageways which are in communication with a mixing chamber in the interior of the inner housing through hot and cold water supply openings.          A  thermostat  construction  responsive  to  the  mixed  water temperature is axially movably disposed in the mixing chamber and is operably connected to valving means adapted to open and close the hot water  supply opening and cold water  supply opening.   The  valving  means  comprise  a  cylinder  fixedly mounted on the top of the inner housing with the bottom of the cylinder and the top of the inner housing defining the hot water  supply  opening,  and  with  the  top  of  the  cylinder defining with an inner shoulder in the cylindrical housing the cold water supply opening, and a piston operably connected to said thermostat construction and axially slidably disposed in said cylinder.  Upward movement of the piston in the cylinder serves  to  close  off  the  cold  water  supply  opening  while downward movement of the piston serves to close off the hot water  supply  opening.   An  increase  in  the  mixed  water temperature in the mixing chamber results in axially downward movement of the thermostatic element with consequent downward movement of the piston thereby resulting in restriction or closure of the hot water supply opening.  A decrease in the mixed  water  temperature  in  the mixing  chamber  results  in axially  upward  movement  of  the  thermostatic  element  with consequent upward movement of the piston thereby resulting in restriction  or  closure  of  the  cold  water  supply  opening thereby maintaining a preselected water temperature in the mixing chamber.
