Patent CA-2072637-A1 (CA)
Title: Method to identify analyte-binding ligands
Inventor: KAUVAR LAWRENCE M
IPC: B01J20/32
Filed: 1990-10-31
Abstract: The invention provides methods to obtain panels of low molecular weight polymers resulting from varying constituent monomers, which panels are systematically diverse with respect to two or more variables. The panels can be screened for members (paralogs) which are capable of specifically binding a target moiety. Such paralogs are useful for chromatographic separations and purifications of desired analytes and in binding assays, such as immunoassays, involving said analytes, as well as for any purpose which requires said specific binding. The invention also provides kits for these determinations, and methods to synthesize panels of candidate paralogs and use of these panels to generate analyte profiles and cross reactivity matrices.

Title: Elastomer with outstanding characteristics for use in making tire tread compounds
Inventor: HALASA ADEL F
IPC: B60C1/00
Filed: 1992-08-13
Abstract: ABSTRACT OF THE DISCLOSURE            ELASTOMER WITH OUTSTANDING CHARACTERISTICS              FOR USE IN MAKING TIRE TREAD COMPOUNDS    It is highly desirable for tire treads to exhibit good traction characteristics such as good wet skid resistance.  However, it has traditionally been very difficult to improve the traction characteristics of a tire without sacrificing rolling resistance and tread wear.  The high performance segmented elastomers of this invention offer a unique combination of desirable characteristics for utilization in making tire tread compositions.  For instance, the rubbery polymers of this invention can be made into tire treads which exhibit outstanding traction characteristics while maintaining good rolling resistance and tread durability.  This invention more specifically reveals a rubber polymer which has an excellent combination of properties for use in making tire treads which is comprised of (a) a first segment which consists essentially of repeat units which are derived from 1,3-butadiene monomer and styrene monomer, wherein the first segment has a vinyl content which is within the range of about 6% to about 15%, wherein the first segment has a number average molecular weight which is within the range of about 25,000 to about 350,000; and (b) a final segment which is comprised of repeat units which are derived from l,3-butadiene and styrene, wherein the repeat units in the final segment are in essentially random order, wherein the final segment has a vinyl content of about 20% to about 95%, and wherein the final segment has a number average molecular weight which is within the range of about 25,000 to about 350,000.
Patent CA-2077952-A1 (CA)
Inventor: MURAY ANDREW J
IPC: G03F1/28
Filed: 1992-09-10
Abstract: A method and apparatus for photolithographically fabricating features on a very large scale integrated circuit wafer by use of a phase shift mask defining discrete regions. This overcomes the problems of intensity nulls at the junction of regions formed by portions of the mask having opposite phase. The mask includes a transition region defining three phases which are assigned to pixels in the transition region, such that the phase assignment of the pixels is synthesized from an algorithm taking into account optical resolution and depth of focus. Each pixel is assigned one of three discrete phases, which thereby creates a transition region simulating a ramp between the two regions of opposite phases, such that intensity variation of the optical image corresponding to the transition region is minimized.

Title: Bifolded mailer with return envelope
Inventor: ASHBY ROBERT E
IPC: B42D5/02
Filed: 1992-10-02
Abstract: A mailer type business form, an intermediate for the form, and a method of making the form are provided. The mailer type business form is constructed from a single ply sheet of pager and a small panel (less than one-quarter the size of the sheet) which cooperates with a quadrant of the sheet to provide a return envelope. The sheet is folded along orthogonal fold lines to provide four plies, a fifth ply being provided by the panel which cooperates with one of the plies to form the return envelope. The mailer is constructed by positively guiding the panel (preferably utilizing a tractor hole strip along one edge) into contact with predetermined adhesive strips on the single ply sheet, and then subsequently folding the sheet along the orthogonal fold lines.

Inventor: CLEMENTS GEORGE J
IPC: B42D5/00
Filed: 1991-09-19
Abstract: A pad assembly comprising a multiplicity of flexible sheets each having a band of repositionable pressure sensitive adhesive coated on its rear surface adjacent and spaced by a small predetermined spacing from a first edge. The sheets are disposed in a stack with the band of repositionable pressure sensitive adhesive on each sheet adhering it to the adjacent sheet in the stack; and a layer of padding compound is disposed over and adhered to aligned first edges of the sheets in the stack. The padding compound allows, after the band of repositionable pressure sensitive adhesive on the rear surface of one of the sheets in the stack is separated from the front surface of the adjacent sheet in the stack, that one sheet (and any sheets above it) to be pivoted away from that adjacent sheet while remaining adhered to the adjacent sheets. The small predetermined spacing between the band of repositionable pressure sensitive adhesive and the first edge of each sheet provides a tactile feel when the band of repositionable pressure sensitive adhesive on the rear surface of one of the sheets in the stack separates from the front surface of the adjacent sheet in the stack that signals the person peeling the sheet away that such separation has occurred, and allows that person to reduce the force he is applying to the sheet, thereby restricting inadvertent separation of that sheet from the padding compound. After a sheet is intentionally separated from the padding compound, the band of repositionable pressure sensitive adhesive on the sheet affords adhesion of that sheet to a vertical surface.

Title: Ionically cross-linked polymeric microcapsules
Inventor: COHEN SMADAR
IPC: A61K49/22
Filed: 1991-10-04
Abstract: A method for encapsulating biologically-labile materials such as proteins, liposomes, bacteria and eucaryotic cells within a synthetic polymeric capsule, and the product thereof, are disclosed. The method is based on the use of a water-soluble polymer with charged side chains that are crosslinked with multivalent ions of the opposite charge to form a gel encapsulating biological material, that is optionally further stabilized by interactions with multivalent polyions of the same charge as those used to form the gel. In the preferred embodiment, hydrolytically stable polyphosphazenes are formed of monomers having carboxylic acid side groups that are crosslinked by divalent or trivalent cations such as Ca2+  or Al3+, then stabilized with a polycation such as poly-L-lysine. A variety of different compositions can be formed from the crosslinked polymer. In a preferred embodiment, microcapsules are made by spraying an aqueous solution of polyphosphazene and material to be encapsulated into a cal-cium chloride solution. A semi-permeable membrane is formed on the microspheres by complexation of the surface carbox-ylate groups with poly(L-lysine).

The control system has N different timing programs for times T1-T2 and T3-T4, each program corresponding to one type of ballast.  In each program times T3 and T4 are constant; only the times T1 and T2 are varied for a series of successively greater power reductions; the maximum power reduction may be as much as 30 to 40 percent.          The system is provided with protection circuits to protect against unusual line or load voltage or current conditions.
