Depending on the inkjet fluid used, the plate may be ready for press immediately following the platemaking operation or further processing may be required.
Patent CA-2398035-A1 (CA)
Title: Timed pulsatile drug delivery systems
Inventor: VISHNUPAD KRISHNA
IPC: A61K9/54
Filed: 2001-02-08
Abstract: A pharmaceutical dosage form such as a capsule capable of delivering therapeutic agents into the body in a time--controlled or position-controlled pulsatile release fashion, is composed of a multitude of multicoated particulates (beads, pellets, granules, etc.) made of one or more populations of beads. Each of these beads except an immediate release bead has at least two coated membrane barriers. One of the membrane barriers is composed of an enteric polymer while the second membrane barrier is composed of a mixture of water insoluble polymer and an enteric polymer.  The composition and the thickness of the polymeric membrane barriers determine the lag time and duration of drug release from each of the bead populations. Optionally, an organic acid containing intermediate membrane may be applied for further modifying the lag time and/or the duration of drug release. The pulsatile delivery may comprise one or more pulses to provide a plasma concentration-time profile for a therapeutic agent, predicted based on both its pharmaco-kinetic and pharmaco-dynamic considerations and in vitro/in vivo correlations.

Filed: 2001-01-12
Abstract: L'invention concerne un procédé d'amélioration de la zone de couverture d'un réseau d'antennes intelligentes permettant de réaliser une mise en forme adaptée de faisceau pour un réseau d'antennes par la définition des paramètres de mise en forme des faisceaux W(n) de n éléments d'antenne conformément à la différence des paramètres de forme et de dimension entre les zones de couverture nécessaires à un projet de travaux et celles qui existent déjà. A cet effet, on détermine la précision de la valeur W(n) nécessaire et on définit les étapes, puis on détermine un groupe de valeurs de départ W0(n), un groupe de valeurs de départ d'approximation des moindres  epsilon 0, une variable de comptage, une valeur seuil M de réglage de fin et la valeur maximale T(n) de puissance d'émission d'un élément d'antenne. Finalement, on accorde la valeur W(n) par boucle de rétroaction conformément aux valeurs définies auparavant. Le procédé d'approximation progressive s'inspirant du principe des moindres carrés moyens permet de régler les paramètres d'émission des antennes de manière que la zone de couverture réelle du réseau d'antennes se rapproche le plus des exigences dans des conditions sensiblement optimales.

Patent CA-2404471-A1 (CA)
Inventor: DALE JAMES LANGHAM
IPC: C12N5/10
Filed: 2001-03-28
Abstract: The present invention relates generally to constructs and in particular genetic constructs comprising polynucleotide sequences capable of release in covalently closed, circular form from a larger nucleotide sequence such as, but not limited to, a genome of a eukaryotic cell. Preferably, once released, a polynucleotide sequence is reconstituted in a form which permits expression of the polynucleotide sequence. In one embodiment, the reconstituted polynucleotide sequence comprises a coding sequence with all or part of an extraneous nucleotide such as, but not limited to, intronic sequence or other splice signal inserted therein. Expression and in particular transcription of the coding sequence involves splicing out the extraneous sequence. The release and circularization is generally in response to a stimulus such as a protein-mediated stimulus. More particularly, the protein is a viral or prokaryotic or eukaryotic derived protein or developmentally and/or tissue specific regulated protein. The construct of the present invention is particularly useful in conferring genetic resistance against pathogens or inducing apoptosis or other cell death mechanisms useful, for example, in treating cancer or inducing male or female sterility in plants. The constructs permit, therefore, site specific expression and/or developmentally regulated expression of selected genetic sequences.

Title: Method and apparatus for reducing crop losses during slab and ingot rolling
Inventor: MASLANKA ANDRZEJ
IPC: B22D11/00
Filed: 2001-05-14
Abstract: A method and apparatus for reducing crop losses during slab and ingot rolling concerns the formation of a slab ingot having a specially configured or shaped butt end and optionally a head end as well. A special shape is formed by machining, forging or preferably by casting. The special shape at the butt end is imparted during casting by a specially shaped bottom block or starter block. The special shape of the bottom block is imparted to the cast ingot butt end. The specially shaped butt end of a slab shaped ingot is generally rectangular in shape and has longitudinally outwardly extending, enlarged portions (24), which slope downwardly toward a depressed central valley region (26). The lateral sides of the enlarged end portions and the depressed valley region carry transversely extending, tapered or curved edges. A similar shape may be imparted to the head end of the ingot at the conclusion of a casting run through the use of a specially shaped hot top mold or by way of machining or forging the cast head end. During subsequent hot rolling in a reversing roughing mill, the specially shaped slab ingot minimizes the formation of overlap and tongue so as to improve material recovery by reducing end crop losses and to increase rolling mill efficiency by increasing metal throughput in the mill.

Title: Spiral wound abrasive belt and method
Inventor: FOLLENSBEE ROBERT A
IPC: B24D9/00
Filed: 2001-05-16
Abstract: A spiral wound abrasive belt (215) is formed from an abrasive media (210) including a plurality of webs. The webs of the abrasive media may include coated abrasives joined by splicing media or other suitable joining material.  Alternatively, the webs may include individual single or multiple layers that form a coated abrasive simultaneously along with the spiral belt (215) without the use of additional joining material. A method of forming the spiral belt (215) includes draping the abrasive media over a fixed hub (220) at an angle to form the spiral belt (215) while abutting the edges of the outermost web and overlapping the outermost web and adjacent web or webs. Heat and pressure may be applied to the joined edges to form a strong bond along the spiral seam. Another method includes introducing the webs forming the abrasive media at an angle and draping the webs over a fixed hub (220). The abrasive media may then be passed around an adjustable hub that provides tension in the spiral belt (215) while allowing for different circumferentially sized belts.  Continuous feeding of the input abrasive media or webs will result in a spiral belt (215) of ever increasing width that may subsequently be slit to a desired width.
