Patent CA-2104236-A1 (CA)
Title: Improved method and apparatus for sequentially stretching zero strain stretch laminate web to impart elasticity thereto without rupturing the web
Inventor: WEBER GERALD M
IPC: B29L9/00
Filed: 1992-01-28
Abstract: An improved method and apparatus for incrementally stretching "zero strain" stretch lami-nate webs to impart elasticity thereto in the direc-tion of stretching, at least up to the point of initial stretching. The "zero strain" stretch laminate mate-rial (1) is formed of at least two plies (4a, 5, 6) of material which are either intermittently or substan-tially continuously secured to one another along at least a portion of their coextensive surfaces while in a substantially untensioned ("zero strain") condi-tion. One of the plies (4a) is stretchable and elas-tomeric, while the second ply (5, 6) is elongatable, but not necessarily elastomeric. The second ply will, upon stretching of the laminate, be at least to a degree permanently elongated so that, upon release of the applied tensile forces, it will not return to its original undistorted configuration. This results in z-direction bulking of the laminate web when the applied tension is released as well as subsequent elastic extensibility in the direction of initial stretching, at least up to the point of initial stretch-ing. In a particularly preferred embodiment of the present invention, the mechanical stretching opera-tion is carried out by passing said laminate web between multiple pairs of meshing corrugated rolls (21, 25, 27), each pair of rolls exhibiting a greater degree of meshing than the preceding pair, to sequentially stretch said web in stages. Sequentially stretching the web in the foregoing manner minimizes damage to the web.

Title: Method and apparatus for treating ground roasted coffee
Inventor: HSU SHENG H
IPC: B01F7/18
Filed: 1994-05-03
Abstract: A method and apparatus for the continuous coun-tercurrent treatment of roast and ground coffee particles in which a bed of the coffee particles is suspended in an aqueous liquid and the suspended bed is agitated in a manner which facilitates removal of evolved coffee gases from the bed to thereby effect complete, uniform wetting and/or extraction of the coffee grounds. The apparatus comprises a tank (10) in which water flows upward from the bottom and is removed from the top of the tank, with fresh coffee grounds being fed onto the liquid at the top of the tank. Two pairs of interleaved blade assemblies (24, 25) are mounted in the tank for relatively counter rotation to submerge coffee particles into the aqueous liquid and form a bed of suspended coffee particles. A submerging auger (41), mounted on a central shaft (21) in the tank, facilitates submerging the coffee grounds in the liquid. Both pairs of blade as-sanblies, which are arranged one above the other, have a set of downwardly extending blade members and an opposed set of upwardly extending blade members inter-leaved with the downwardly extending blades. One of the sets of blade members in each pair is stationary and the other set of blade members is mounted for rotation on the central shaft. A screw conveyor (47) is mounted on the side of the tank at the base of the suspended bed to remove grounds from the base of the suspended bed and thereby control the height of the bed in the tank. Coffee grounds which settle to the bottom of the tank are removed by suitable means.

Title: A chemical system for providing fibrous materials with stain resistance
Inventor: NGUYEN VAN GIAO
IPC: D06P5/04
Filed: 1993-08-27
Abstract: Method for imparting stain resistance to fibers, especially wool, which is adaptable to current wool processing methods. Steps comprise: A) treating fibers with a mordant; B) treatment with a combination of sulfonated or disulphonated surfactant to-gether with a stain resist (e.g., syntan); and C) providing treatment with a fluorochemical in either step A, or B, in an amount suf-ficient to improve stain resistant properties. The improved method may be undertaken in the liquor remaining in a dye bath after dyeing fiber (spent bath process). Process pH is acid - 1.5 - 3.0 percent. Advantage: lowers the proportion of stain resist chemical to wool necessary to impart stain resistance. Tip sealing, using polymethacrylic resin and fluorochemical, may be an added step.

Patent CA-2157957-A1 (CA)
Title: Capillary connector
Inventor: PICHA NEIL ROBERT
IPC: G01N30/60
Filed: 1995-09-11
Abstract: A capillary column connector assembly includes a pair of body members fabricated from a resilient, inert ceramic having high compressive strength. Each body member has an inwardly tapering longitudinal throughbore within which the end of a capillary column can be inserted by press-fitting. A split sleeve holds the two body members in mutually facing alignment with inner end surfaces in compressed mutual contact. The inner end surfaces are slightly radiussed in order to deform upon compression to provide a fluid-tight seal surrounding the junction between the inner ends of the longitudinal bores, thereby eliminating the need for any separate sealing gasket. A mechanical assembly comprising an inner spool, an outer housing, a spring, and a bearing-mounted support provide axial compression forces tending to urge the ceramic body members into mutual facing contact with the radiussed surfaces deformed.

Abstract: ABSTRACT OF DISCLOSURE       A process is described for producing fertile hybrid seed or hybrid seed comprising fertile and sterile seed using male-sterile  plants  created  by  employing  molecular techniques to manipulate anti-sense gene and other genes that are capable of controlling the production of fertile pollen in plants.  Transformation techniques are used to introduce constructs containing anti-sense DNA and other genes into plants.   Said plants are functionally male-sterile and are useful for the production of hybrid seed by the crossing of said male-sterile plants with pollen from male-fertile plants.  Hybrid seed production is simplified and improved by this invention and can be extended to plant crop species for which commercially acceptable hybrid seed production methods are not currently available.
