Abstract: There is disclosed a filled paper composition comprising intact cellulose fibers and fillers wherein the cellulose fibers are originally never-dried, and wherein the filler material is in an insoluble precipitate formed in situ within the cell wall of the never-dried cellulose pulp fibers. The filled paper composition is characterized by having increased strength characteristics relative to a corresponding conventionally loaded paper composition containing the same amount of the same filler material. There is also disclosed a process for the production of filled paper using never-dried pulp fibers and filler comprising an insoluble precipitate that is precipitated in situ within the cell wall of the fibers. The process first immerses the never-dried pulp fibers in a first solution containing a soluble salt or salts, filters the pulp fibers from the first solution, and reimmerses the never-dried pulp fibers containing the first solution in the pores into a second solution, wherein the second solution comprises soluble salt or salts different from those of the first solution and able to form an insoluble precipitate with the salt or salts of the first solution. The filled, never-dried pulp fibers are filtered and washed and either used to form filled paper products or dried to filled pulp fibers for later use in papermaking.

Title: Illuminating apparatus
Inventor: COWLING IAN R
IPC: E06B7/082
Filed: 1990-09-07
Abstract: There is provided illuminating apparatus including an illuminating channel (10) defined between an incident surface (11), an emergent surface (12), an upper surface (13) and a lower surface (14).  The upper surface (13) includes end portions (15) which may be adhered to the lower end portions (16) of an adjacent illuminating channel. The portion of the upper surface (13) between the end portions (15) comprises a steeply inclined outer portion (17), a horizontal central portion (20) and a shallow inner inclined portion (21). Light entering the incident face (31) at a low angle of incidence is reflected by total internal reflection in turn from the lower outer surface (32) of a first cavity (33), the central portion of the upper surface (34) of a second cavity (35), and then the inner lower surface (36) of the first cavity (33) before emerging from the emergent face (37). Light entering the incident face (31) at a medium angle of incidence is refracted at the incident face to a lower angle of refraction such that most incident light is reflected from locations distributed along the upper surface (40) of the cavity (41). Light entering the incident face (31) at a high angle of incidence is refracted to a lower angle such that most incident light falls on the outer end of the upper surface (42) of the cavity (43), such that the light rays are deflected through an angle sufficient for them to emerge from the emergent face (37) diffused and approximately perpendicular to the latter.

Title: Reactor for heterogeneous-phase reactions
Inventor: PIOTROWSKI BERNHARD
IPC: B01J10/00
Filed: 1992-05-27
Abstract: Abstract A reactor for carrying out heterogeneous-phase reactions, in particular gas/liquid reactions with a continuous liquid phase and a disperse (discontinuous) gas phase, is described, in which, in a horizontal plane, a substantially vertically upward-directed flow of the reaction medium takes place in part regions of the reactor cross-section and a substantially vertically downward-directed flow takes place in other part regions, the reactor having means for dispersing the discontinuous phase sub-stantially only in the part regions with upward-directed flow.          The reactor is here designed in such a way that free flow of the reaction medium from the part regions with downward-directed flow to the part regions with upward-directed flow is possible in the region of the dispersing means.   The preferred use of the pro-posed reactor is the exothermic oxidation of p-xylene and monomethyl p-toluate with air in the so-called Witten PMT process.

Abstract: Abstract of the Disclosure An electric coupling for two electric circuits in a well includes an electric contact and a contact receiver connected to respective ones of the circuits so that a contact/receiver pair  is  formed when the contact and receiver  are moved together.  The receiver is sealed by a sealing member.  The sealing member is disposed so that it is penetrated by the contact when the contact and receiver are moved together.  A coupling including two such pairs  is preferably used to connect two electric wires in the well to form a current conductive loop linking two electric coils.  One of the coils is adapted to be moved in the well relative to the other coil which is adapted to be fixed in the well.   In a preferred embodiment, one coil is on a wireline tool and the other coil is  on  a  downhole  tool.    The  current  conductive  path established across an intervening space between the tools is electrically insulated from the bodies of the tools and preferably has a resistance sufficiently low that the current conductive path is not effectively short-circuited by fluid in the intervening space which the path crosses.

Title: Posted write disk array system
Inventor: SCHNEIDER RANDY D
IPC: G06F11/10
Filed: 1993-06-04
Abstract: ABSTRACT             POSTED WRITE DISK ARRAY SYSTEM      A posting memory used in conjunction with a drive array to increase the performance of fault tolerant disk array write operations.  When the posting memory flushes dirty data back to the disk array, the posting memory coalesces or gathers contiguous small write or partial stripe write requests into larger, preferably full stripe writes.  This reduces the number of extra read operations necessary to update parity information. In this manner, the actual number of reads and writes to the disk array to perform the transfer of write data to the disk array is greatly reduced.  In addition, when the posting memory is full, the posting memory delays small, i.e., partial stripe writes but allows full stripe writes or greater to pass directly to the disk array.  This reduces the frequency of partial stripe writes and increases disk array performance.
