Patent CA-2081398-A1 (CA)
Inventor: FRIEND WILLIAM H
IPC: D21C9/10
Filed: 1992-10-26
Abstract: Unbleached pulp is washed with an aqueous alkaline solution in a wash press to substantially uniformly distribute a first amount of alkaline material throughout the pulp.  The consistency of the pulp exiting the wash press is above about 18%, preferably between 25 to 35 percent by weight, and the high consistency alkali containing pulp is then treated with oxygen to effect /  The use of a wash press reduces the overall amounts of alkaline material utilized in the process compared to processes which add alkaline material to the pulp at low consistency.  Additional alkali may be applied, if desired, onto the high consistency pulp prior to oxygen delignification to provide a total amount of between 0.8 and 7 percent by weight of oven dry pulp. High strength, low lignin pulps are formed after oxygen delignification which may be further bleached to high brightness with reduced amounts of bleaching chemicals.

Abstract: Articles having a complex geometric configuration have hydrophilicity imparted to at least a portion of surfaces of the articles while substantially retaining the complex geometric configuration.  The hydrophilicity is imparted by an extremely thin, self-interlocking shell of tactic, hydrophilic poly(vinyl alcohol) enveloping the surfaces. A tactic poly(vinyl alcohol) precursor applied to surfaces of the supporting structure is reacted in situ on the surfaces with a hydrolysis reagent to prepare the tactic, hydrophilic poly(vinyl alcohol) shell. The article having the hydrophilic shell is highly resistant to solvent washout. Hydrophilicity and hydrophobicity can be reversibly provided on regio-specific surfaces of the article. Articles in the form of membranes useful as filters, residue barriers for electroplating devices, separators for electrochemical cells, and drug delivery device components are also described. Membranes to form permanent and undistorted images, and methods of preparing such images from image-forming substances in receptive media are also provided. Hydrophilic porous supporting structures loaded with an enzyme system which catalyzes a reaction of a substrate, oxygen, and if necessary, water or moisture to consume oxygen are also described for oxygen scavenging in packages containing oxygen sensitive products.

Title: Method and apparatus for a multiple font display
Inventor: KEEN DONALD M
IPC: G09G5/24
Filed: 1994-10-17
Abstract: A method and apparatus for displaying more than one font on a limited dot matrix display device are disclosed. In addition to displaying characters in a standard font based on using all pixels in a five by seven pixel matrix, a custom font set based on a reduced size pixel matrix is used for character display.  A maximum of four columns and six rows of pixels, i.e., a four by six matrix, are used for the custom font out of the five columns and seven rows of pixels which are available.  In further embodiments of the invention, the pixels which are not used to create a character may be used to add a background characteristic. Thus a reverse video font or underlining font may be created.  In an additional embodiment, a box can be placed around a word by using the underline font in conjunction with placing a vertical line immediately before the first character and immediately after the last character of a word to be placed in a box.

Patent CA-2123450-A1 (CA)
Inventor: IMAINO WAYNE I
IPC: G11B7/24
Filed: 1994-05-12
Abstract: An optical data storage system uses an optical medium made of a stack of spaced-apart optical disks.  Each disk in the stack is made of light-transmissive material, such as polycarbonate when the system is a CD-ROM system, and has a partially light-transmissive data layer on at least one of its faces.  A focusing lens in the system focuses light to the data layers along optical paths, with each data layer corresponding to a unique optical path length.  The light is focused to each data layer by reflection off adjacent data layers such that the total substrate thickness through which the light passes is the same for each optical path.  In this manner, the fixed spherical aberration correction provided by the focusing lens  is  adequate  and  variable  aberration  correction  is  not necessary.   By appropriate selection of reflectivities of the multiple data layers in the disk stack, it is possible to design the system so that the effective reflected light intensity from each  data  layer  is the  same,  and  that  adjustable  signal amplification is not necessary.
