Title: Method and apparatus for the production of multiply cellulosic board and product obtained thereby
Inventor: SELF R WAYNE
IPC: D21J1/00
Filed: 1992-04-22
Abstract: ABSTRACT OF THE DISCLOSURE              METHOD AND APPARATUS FOR THE PRODUCTION     OF MULTIPLY CELLULOSIC BOARD AND PRODUCT OBTAINED THEREBY           A method and apparatus for the production of multiply cellulosic fiber board wherein first and second streams of cellulo5ic pulp are deposited on a wire, partly dewatered, mechanically integrated and conditioned to form a bilayered web, followed by thc deposition of a third stream of cellulosic pulp onto the top of the bilaycred web and further dewatering in a flow direction opposite the di.rec-tion of flow of the dewatering of the bilayered web to hydraulically integrate and form a trilayered web.  Prefera-bly, the total quantity of fibers contAincd in the seconc1 (inner)  layer is greater than the quantity of fibers in either the first or third outer layer, thereby developing a board product that exhibits an appareIlt bulk at least equal to the apparent bulk of a single layer board formed from the same quantity of fibers, but containing between about 9% and 11% fewer fibers than such single layered board.  The novel product exhibits substantially improved physical and other properties,especially stiffness.  Coating of the board with a polymer and formation of the  coated board into liquid containers is disclosed.     U.S. APPLICATION SERIAL NO. 071690,518

Title: Reflective and transmissive document reading apparatus and a method of reading a document
Inventor: TANAKA KENJI
IPC: H04N1/10
Filed: 1993-05-13
Abstract: A scanner provided with means for reading both reflective and transmissive documents, comprises: two CCD sensors, one for reflection mode to read reflective documents, and the other for transmission mode to read transmissive documents, disposed respectively on one side of a light source, and on the opposite side thereto with a document table therebetween; and a reflective/transmissive document mode discriminating means wherein, when a light source is turned on, a judgment is made on whether or not light to be transmitted is blocked. The circuits of CCD sensors can be automatically changed between transmission mode and reflection mode. Specifically, a reading window disposed in a transmissive document reading unit is equipped in a detachable manner with either a blocking member for preventing light from entering the transmissive document reading unit, or a diffusing plate for scattering incident light so as to introduce uniform light into said transmissive document reading unit. Alternatively, light from light sources is color-separated by dichroic mirrors into blue, red and green light beams, and thus obtained desirable light is reflected and transmitted through a beam splitter to read a document with no diffusing plate. In this case, light beams are aligned in proceeding direction by the dichroic mirrors, so that color reproduction performance of an original document having unevenness can be improved.
