23 Kraft pulp is bleached to acceptable brightness without the use of chlorinated organic compounds, yet it still has commercially acceptable strength properties. During production of the kraft pulp it is subjected to extended delignification, by adding kraft white liquor to a first recirculation loop in the digester, and a second, wash, recirculation loop in the digester. Then the pulp is subject...

A hook member positioned beneath the front housing ...

The device comprises a body 17 carrying a tank 22 containing the ink 15 under pressure which communicates with a series of orifices 33. Normally the input 34 to each of the orifices 33 is closed off by a portion 42 of a membrane 38, on which acts a pin 49 actuated by the armature 71 of an electromagnet 51. The tank 22 has the shape of a solid of revolution and the orifices 33 are arranged concentr...

A stripping apparatus for stripping metal film from a metallized plastic film is provided. In accordance with one aspect of the invention, a rod is utilized for providing an anode or cathode charge, with the rod movable in a direction perpendicular to the direction of movement of the metallized plastic film. As a result, any remnants which may accumulate on the rod from a previous stripping operat...
