Title: A latent mercaptan as a heat stabilizer
Inventor: NORRIS GENE KELLY
IPC: C08K5/378
Filed: 1998-06-12
Abstract: Both flexible and rigid vinyl chloride polymer compositions comprising a latent mercaptan-containing heat stabilizer are substantially free from the offensive odor typically associated with mercaptans and are protected during processing by the degradation products of the latent (i.e., blocked)  mercaptan which include a free mercaptan.  The free mercaptan thus released enhances the activity of metallic-based heat stabilizers such as zinc carboxylates and organotin carboxylates and mercaptides in the polymer composition.  Other products of the degradation are believed to include carbocations of the blocking moiety which are stabilized by  a molecular  structure  in which  the  electron deficiency is shared by several groups. The latent mercaptan is selected from the group consisting of a 2-S-(tetrahydropyranyl)-thioalkanol and a carboxylic acid ester thereof.
Patent CA-2243651-A1 (CA)
Inventor: DUCHARME PAUL EDMUND JR
IPC: A22C13/00
Filed: 1998-07-21
Abstract: Disclosed is a method of extruding a solution of cellulose and an amine oxide cellulose solvent as a tube about a sizing mandrel which diametrically stretches the extruded tube. An aqueous PEO solution is introduced into the interior of the extruded tube to facilitate passage of the tube over the sizing mandrel and to extract the amine oxide cellulose solvent from the tube. After such extraction, the aqueous PEO solution containing the extracted amine oxide cellulose solvent is contacted with an anion exchanger to remove the PEO so the amine oxide cellulose solvent can be recovered.

Title: Pin m iii gene in white pine
Inventor: MISRA SANTOSH
IPC: C12Q1/68
Filed: 1998-09-15
Abstract: A gene coding for Pin m III, which is associated with overwintering and frost hardiness in western white pine, has been cloned and characterized. The gene contains an open reading frame of 486 base pairs, encoding a protein of 161.  amino acid residues, with a calculated molecular weight of 18002.30 daltons.  The predicted isoelectricl point is 5.534. The gene is transcriptionally regulated with the highest expression in fall and winter months. The protein Pin m III is high in infected tissue such as canker. Accordingly, the gene can be used to determine frost hardiness and blister resist fungus susceptibility in conifers.
Patent CA-2245769-A1 (CA)
Inventor: SEARS JAMES T
IPC: G06V30/10
Filed: 1997-02-11
Abstract: An optical-input print reading device (1) for people with impaired or no vision in which the user passes a mouse assembly (2) containing a camera (25) over the text to be read. Images of this text are input to a computer (3), which decodes the images into their symbolic meanings through optical character recognition (31). By assembling words together from overlapping groups of text elements, whole words are created. Using also the recognized character position output of the optical character recognition (31), the computer (3) directs a linear tactile display (53) contained within the mouse (2) assembly to indicate to the user the presence and vertical alignment of recognized alphanumeric text under the unit. This feedback allows the user to locate and properly align and guide the mouse (2) assembly across the text to be read. Furthermore, through a speech synthesizer (61), the words are spoken audibly as they are passed over. As the divice requires only one hand to operate, its uses include reading food packaging, pill bottlles, currency, and price tags, as well as printed sheets. In a portable form, this device provides a means for low-vision and blind people to function more fully in their everyday lives.
