Abstract: METHOD OF BLEACHING OR DELIGNIFICATION      OF CELLULOSE PULP WITH OXYGEN           ABSTRACT A continuous method of bleaching or delignification of cellulose pulp with oxygen.  The pulp in the form of an aqueous slurry is passed through a diffusing and mixing conduit at a velocity at which it behaves as a turbulent liquid and then through a holding vessel at a velocity at which it assumes plug flow.  An oxygen-steam mixture is diffused through a microporous wall interfacing with the slurry in the conduit to form a mass of small oxygen bubbles from which the steam condenses imparting heat to the slurry and leaving the oxygen in the form of smaller bubbles dispersed throughout the slurry, presenting a total surface area markedly greater than bubbles resulting from the injection of oxygen alone through the same microporous wall under the same conditions.  The oxygen bubbles remain dispersed throughout the slurry when it assumes plug flow, to give time for the oxygen to exert its bleaching effect.  Apparatus for carrying out the method.

Title: Thermally stable photoresists with high sensitivity
Inventor: BRUNSVOLD WILLIAM R
IPC: H01L21/027
Filed: 1987-07-20
Granted: 1992-10-13
Abstract: ABSTRACT OF THE DISCLOSURE      The    present    invention    discloses    particular lithographic  polymeric  materials  and  methods  of  using these materials, wherein the polymeric materials have acid labile  or  photolabile  groups  pendant  to  the  polymer backbone.    The  polymeric  materials  are  sufficiently transparent  to  deep  UV  radiation  to  permit  deep  UV imaging, can be used to produce resist structures having thermal  stability  at  temperatures  greater  than  about 160°C,   and  are  sufficiently  resistant  to  excessive crosslinking  when  heated  to  temperatures  ranging  from about 160°C to about 250°C that they remain soluble in common lithographic developers and strippers.  The present invention also discloses  resists comprising substituted polyvinyl   benzoates   Which,   after   imaging,   exhibit unexpectedly high thermal stability, in terms of plastic flow.   These  resists  cannot  be  imaged  using  deep  UV because they exhibit such a high degree of opacity below 280nm; however, they are useful as the top, imaging layer in a bilayer resist process wherein the top layer acts as a  mask  during  deep  UV  exposure  of  the  bottom  layer.

Title: Apparatus for treatment of ore particles
Inventor: PARRENT KENNETH G
IPC: C22B3/02
Filed: 1987-09-25
Granted: 1992-01-28
Abstract: APPARATUS FOR TREATMENT OF ORE PARTICLES    A B S T R A C T A high-velocity jet of solvent is introduced through a nozzle into one end of a passage.  A slurry of ore particles is feed into the passage through a narrow inlet port extending across the width of the passage in front of the nozzle of the jet.  The resulting high-energy impact of the solvent jet on the ore particles causes a rapid, turbulent flow of the mixture of solvent and ore particles through the remaining length of the passage and into a mixing chamber.  This flow impinges on the back wall of the mixing chamber further increasing abrasion and mixing between the solvent and ore particles.

Title: Microwave transformer
Inventor: MORGAN THOMAS E
IPC: H01P5/10
Filed: 1988-02-10
Granted: 1991-04-23
Abstract: ABSTRACT                    Microwave Transformer An improved microwave balun transformer providing an extension of operating frequency range particularly in conjunction with a cavity-backed spiral antenna.  The balun cavity has a dipole extending between an unbalanced coax port and an opposite end wall, the dipole junction being connected to a balanced twin line.  The improvement consists in effectively controlling the length of the cavity to make it closer to (two) quarter-wave stubs by inserting a frequency dependent reflector at each end of the dipole.  At low frequencies the reflectors are transparent thus giving the full length of the cavity, while at high frequencies the reflectors reflect and effectively shorten the cavity.
