Patent CA-2298413-A1 (CA)
Title: Composite containment device and method of making it
Inventor: SCOTT STEUART
IPC: B32B27/12
Filed: 2000-02-11
Abstract: A composite is made from a liquid impermeable surface treated non-woven polypropylene fiber fabric and a surface treated polypropylene mesh adhered together with a thermosetting resin system. The thermosetting resin system has a surface tension at least dynes/cm at 20° C less than the surface energy of both the mesh and fabric. The fabric-mesh composite can be laid into molds or forms, or wrapped around a mandrel. Alternately the fabric-mesh composite can be laid into molds or forms, or wrapped around a mandrel and then wetted with an appropriate resin system. The object is then allowed to cure, either at ambient temperature or by force curing with the addition of heat.
Patent CA-2299345-A1 (CA)
Inventor: HEFFELFINGER DAVID M
IPC: C12M1/00
Filed: 1998-08-11
Abstract: Cette invention se rapporte à un appareil capable de mesurer des quantités d'échantillons biologiques ou autres ayant été marquées au moyen de n'importe quelle technique choisie parmi une grande variété de techniques, telles que la fluorescence, les radio-isotopes, les agents chimiques photoémetteurs activés par enzyme et les substances fluorescentes activées par enzyme. Ce scanner comprend un module source (113) qui contient de préférence un laser interne émettant deux longueurs d'ondes différentes ayant approximativement la même intensité. Une source lumineuse externe optionnelle peut être couplée à ce module source, lui conférant ainsi une flexibilité supplémentaire par l'addition d'autres longueurs d'ondes (par exemple UV, lumière visible, infrarouge moyen et infrarouge). Ce scanner comprend également un module de détection (115), à l'intérieur duquel sont montés deux détecteurs, ce qui permet la détection simultanée de longueurs d'ondes multiples. Un câble optique fourchu (111) sert à transférer la lumière d'excitation et/ou d'interrogation du module source à l'échantillon et à transférer ensuite la lumière émise et/ou dispersée de l'échantillon au module de détection.

Title: Pressure overload indicator system for power toothbrushes
Inventor: MEGINNISS STEPHEN M
IPC: A46B15/00
Filed: 1998-07-20
Abstract: A power toothbrush (10) has a brushhead (13) mounted at one end thereof, the brushhead (13) including a base mounting element (20) for bristles (22) which extend from one surface (43) thereof. Extending from the opposing surface of the base mounting element (20) is a pressure contact member (64). A substantially rigid brushhead shield (32) extends along and is adjacent to the opposing surface of the brushhead (13). The brushhead (13) has a hinge-like portion (28) which permits the brushhead (13) to move or swivel in response to pressure being placed on the brushhead (13), while the brushhead (13) is moving back and forth at its operating frequency of its normal brushing action at over 150 Hz. Thin electrical switch contacts (44), which are part of an electrical circuit (50), are positioned on the brush shield (32), spaced from the contact member (64) on the brushhead (13). When sufficient pressure is applied against the brushhead (13), the brushhead (13) moves sufficiently about the hinge (28), while also continuing to move in normal action that the pressure contact member (64) comes into contact with and then closes the switch contacts (44), closing the electrical circuit (50) and resulting in a visual indication (58, 59) that the brushhead (13) pressure has exceeded the maximum limit for desirable brushing pressure.

Title: Gas-liquid contactor with liquid redistribution device
Inventor: GANSLEY RAYMOND RAULFS
IPC: B01D47/06
Filed: 1998-11-16
Abstract: A gas-liquid contactor for removing gases and particulate matter from flue gases produced by processing operations of the type carried out in utility and industrial plants. The contactor is generally an open spray absorber having a spray tower (110) whose walls (114) form a passage within the tower (110).      Flue gases are introduced into the tower (110) so as to flow vertically upward or downward through the passage. Disposed within the passage are heads (116) for introducing a liquid (118) into the passage such that the liquid (118) contacts the flue gases. A portion of the liquid (118) contacts the wall (114) of the tower (110), such that the portion of the liquid (118) flows downwardly along the wall (114). The tower (110) is equipped with a deflecting device (122) disposed on the wall (114) for deflecting the portion of the liquid (118) away from the wall ( 114), and thereafter reintroducing the portion of the liquid (118) into the passage so as to contact the gases flowing through the passage. The deflecting device (122) is also preferably configured to obstruct the flow of gases along the wall (114) in order to reduce gas penetration at the wall (114) and divert the gases toward the center of the passage where more efficient contact with the liquid (118) is made.
