Title: New polymers, process for making them and coating compositions containing them, especially thermosetting acrylic gel coat compositions
Inventor: KARR GREGORY SCOTT
IPC: C08F4/00
Filed: 1997-10-30
Abstract: An invention is disclosed which pertains to components for gel coat compositions, a process for making such gel coat compositions, and a process for making gel coated articles. Low molecular weight unsaturated polymers which incorporate multiple pendent and/or terminal acrylic or methacrylic vinyl groups are made by the addition polymerization of acrylate/methacrylate monomers with epoxy acrylates such as glycidyl methacrylate, followed by ring opening of the oxirance via action of a (meth)acrylic acid in combination with a ring-opening catalyst to produce the final unsaturated polymer. Gel coat compositions containing such polymers possess improved rheological properties and may be used to create durable in-mold coatings for articles requiring good hydrolytic stability and UV resistance.

Filed: 1998-05-18
Abstract: La présente invention concerne un ensemble serpentin utilisé pour l'occlusion vasculaire comprenant un serpentin primaire enroulé en hélice pouvant ensuite être enroulé pour adopter une forme secondaire. Un élément résistant à l'allongement s'étend à travers la lumière formée, ledit élément étant fixé au serpentin, directement ou indirectement, à au moins deux endroits. Cet élément est de préférence quelque peu détendu à l'intérieur de la lumière de manière à éviter que le serpentin se rompe, se bloque, et, par conséquent, se raidisse lors de son passage par les courbures à l'intérieur du corps humain. La fonction première de l'élément résistant à l'allongement est d'éviter que le serpentin s'allonge pendant son déplacement, par exemple, par le retrait ou le repositionnement après déploiement. Le dispositif peut prendre par lui-même une forme secondaire à partir d'un serpentin primaire enroulé en hélice, préformé de manière linéaire à l'origine. Ce dispositif est en général introduit dans le corps au moyen d'un cathéter. Il est passé axialememt à travers la gaine du cathéter, ne prenant sa forme secondaire qu'après sa sortie du cathéter.

Patent CA-2295810-A1 (CA)
Title: Soluble coated chewable tablet
Inventor: GERGELY GERHARD
IPC: A61K9/00
Filed: 1998-06-03
Abstract: The invention relates to soluble coated chewable tablets. The tablets contain chewing constituents, syrup constituents, fat or wax constituents, and optionally, fillers. The tablets are obtained by mixing the chewing constituents with the melted fat or wax constituents. At least one syrup constituent is added to the mixture which then becomes a crumbly material. That material subsequently is cooled to below 0 °C, ground to a particle size of 5 mm at the most, and, after it has been cooled to below 10 °C, is compressed into tablets. The tablets then are coated. Due to the compression of the cooled granulate particles, the finished product has a partially granular structure in which the moisture has been temporarily immobilized by low temperature. After compression, this moisture is remobilized by heating (especially during the coating process), and migrates or diffuses into the water-soluble ingredients present. The ingredients are partially dissolved and produce a highly viscous, thixotropic, chewable material.

Filed: 1998-10-06
Abstract: A system (100) for mitigating intermittent interruptions in an audio radio broadcast system is provided wherein a primary radio signal and a redundant radio signal are transmitted from a transmitter subsystem (120) and received by a receiver subsystem (140). The output (112) of an audio source (110) is coupled to a modulator (160) for modulating a radio frequency signal (162) for coupling to a transmit antenna (172). A second output (114) of audio source (110) is coupled to a delay circuit (116), for adding a predetermined time delay thereto. The delayed audio source signal is coupled to a modulator (164) for modulating a second radio frequency signal (166) that is also coupled to the transmit antenna (172). The receiver subsystem (140) receives both the primary radio signal and the delayed redundant radio signal and couples each to a respective demodulator (180, 182). At least demodulator (180) includes a circuit (181) for determining the degradation in the primary radio signal and provides a quality measurement output signal (186) to a blend control circuit (190). The recovered primary audio signal from demodulator (180) is coupled to a second delay circuit (184), the time delay of second delay circuit (184) being substantially equal to the time delay of delay circuit (116). The audio output from delay circuit (184) and the redundant audio output from demodulator (182) are coupled to a blending subsystem (135), wherein each is combined with a weighting factor and then combined together to form a composite audio signal for coupling to the audio output circuit (150).

Title: Radiation activation and screening of catalyst libraries for catalyst evaluation and reactors therefor
Inventor: ATKINS MARTIN PHILIP
IPC: G01N31/10
Filed: 1998-10-08
Abstract: Rapid screening for activities and selectivities of catalyst libraries having addressable test sites is achieved by contacting potential catalysts at the test sites with reactant streams forming product plumes at the addressable test sites. The product plumes are screened by passing a radiation beam of an energy level to promote formation of specified photoions and photoelectrons which are detected by microelectrode collection in situ in proximity to the respective addressable test site. Product plumes may be screened row by row or all product plumes emanating from an entire catalyst library may be simultaneously screened. Suitable reactors and microreactors for radiation activation screening are disclosed.
