Title: Electrode membrane etanche pour pile a combustible electrochimique
Inventor: STECK ALFRED E
IPC: H01M8/02
Filed: 1992-06-01
Abstract: Montage d'électrode à membrane avec garniture étanche pour cellules électrochimiques utilisant des matériaux pour assurer l'étanchéité à la périphérie de la membrane d'échange ionique plutôt que d'utiliser la membrane elle-même comme joint d'étanchéité. La garniture étanche peut être faite d'élastomères se prêtant au collage à froid ou à chaud sous pression. Un élastomère thermoplastique non hydrophile est le matériau préféré à cette fin. Le montage d'électrode à membrane avec garniture étanche forme un joint entre les plaques de séparation conductrices qui est plus à la fois plus efficace et plus économique que les montages utilisant la membrane elle-même comme joint étanche. Dans une autre version de l'invention proposée, un montage de membrane pour utilisation dans la section humidification d'une pile à combustible fait appel à un matériau d'étanchéité à la périphérie d'une membrane perméable à l'eau.

Patent CA-2105858-A1 (CA)
Inventor: LEFLOND ODILE
IPC: C12M1/107
Filed: 1992-03-11
Abstract: 2105858 9216613 PCTABS00160 La présente invention concerne un réacteur mélangeur tournant immergé. Il est cylindrique à axe horizontal. Il tourne pour provoquer l'homogénéisation de la matière contenue grâce à des éléments de retournement, fixés sur la paroi interne du réacteur. Il est animé d'un mouvement de rotation de quelques tours, dans chaque sens de marche. Il est relié à son environnement fixe, par des tubes souples qui s'enroulent et se déroulent alternativement. Des moyens sont prévus pour éviter les entrées de matières solides, dans les tubulures d'extraction de gaz, et la quantité de matière contenue dans le réacteur est connue à tout moment grâce à des organes de pesée (32) qui portent les moyens (33 et 15) sur lesquels repose la rotation. Le réacteur est immergé dans un bain de liquide (34). La charge due à l'effet de la pesanteur, sur les paliers (15), est automatiquement annulée par la variation de la hauteur du liquide qui entoure le réacteur, en fonction de la charge que celui-ci contient. Cette disposition a pour avantage d'avoir des paliers qui n'ont plus qu'un rôle de guidage et non de soutien, ils seront donc beaucoup moins onéreux. De plus, la virole du réacteur n'aura à supporter ni sa propre masse ni la pression due à la charge statique de hauteur de matière. Ce bain de liquide permet de résoudre également le problème du maintien en température de la matière, par réglage de la température du bain.

Title: Ion-capture assays using a binding member conjugated to carboxymethylamylose
Inventor: ADAMCZYK JANINA
IPC: G01N33/531
Filed: 1992-04-10
Abstract: The present invention includes novel assays employing a capture reagent, involving a first binding member conjugated to a polymeric anion such as carboxymethylamylose, and a solid phase material containing a reaction site comprising a polymeric cation substance. A test sample suspected of containing the analyze of interest may be contacted with the capture reagent to form a charged capture reagent/analyte complex. The complex is then contacted to the oppositely charged solid phase to attract, attach, and immobilize the capture reagent/analyte complex. The use of carboxymethylamylose to prepare a suitably charged capture reagent provides a superior capture reagent that is capable of binding and retaining the analyze on the solid phase even in the presence of polyanionic non-specific binding blockers.

Title: Method for indirect chemical reduction of metals in waste
Inventor: NAGEL CHRISTOPHER J
IPC: C22B5/00
Filed: 1993-04-23
Abstract: An environmentally sound process is described for the remediation of waste materials that allows the separation, recovery and decontamination of metals. The method includes chemically reducing essentially all of a reducible toxic and potentially hazardous metal-containing component of a waste composition. The waste is directed into a molten metal bath, including a first reducing agent which, under the operating conditions of the molten metal bath, chemically reduces a metal of the metal-containing component to form a dissolved intermediate. A second reducing agent is directed into the molten metal bath. The second reducing agent, under the operations of the molten metal bath, chemically reduces the metal of the dissolved intermediate. The rate at which the second reducing agent is directed into the molten metal bath, relative to the rate at which the component of the waste is directed into the molten molten metal bath, is sufficient to cause essentially all metal-containing intermediate formed to dissolve in the molten metal bath, thereby indirectly chemically reducing the component of the waste. This indirect reduction technology can remediate a variety of materials, including ash metal-contaminated municipal waste, vitreous slag-like materials and spent metal catalysts, while allowing the recovery of remediable metals.
Patent CA-2135359-A1 (CA)
Title: Flow control valve assembly
Inventor: KLINE KEVIN B
IPC: G05D23/13
Filed: 1994-11-08
Abstract: A fluid condition controlled mixing valve assembly includes a valve body having a warm fluid inlet, a relatively chilled fluid inlet, a fluid mixing chamber, and a fluid outlet in communication with the mixing chamber. A thermally responsive control member, or thermostat, is disposed within the mixing chamber. A cylindrical liner is situated within the valve body with openings for chilled fluid flow and warm fluid flow. Concentrically located piston and valve disc are connected through an actuator to the thermostat so that the piston and disc move according to the thermostat response to the fluid temperature in the mixing chamber. The piston controls flow through the fluid openings. The liner and the shuttle define primary and secondary passageways. Fluid flows through the primary passageway when the flow control member is in a normal operating condition, i.e., with substantial fluid flow through both inlets. If flow through one of the inlets ceases, the shuttle moves to a failure condition, in which substantially all flow from the inlets is directed through a secondary passageway. This provides a fluid of a desired condition when there is substantial flow through both inlets and a fluid of a less desirable but acceptable condition when substantial flow through one of the inlets ceases.

Patent CA-2154866-A1 (CA)
Inventor: NEFF CRAIG A
IPC: B32B27/00
Filed: 1994-01-28
Abstract: An extrudable material (1), such as a hot melt adhesive, is applied to a substrate (2) with simultaneous irradiation by a laser beam (9). The energy of the laser is absorbed by the adhesive and the substrate to cause the adhesive to spread into the fabric. When applied to a gap (17) between two substrate sheets, the extrudable material creates a very strong bond. When one of the substrate materials (21) is porous, the extrudable material will penetrate the thickness of the material and contact a lower layer (19) to form a bond. The extrudable material is applied through a nozzle, and the laser beam is directed through the nozzle to be coaxial with the flow path (11) of the extrudable material. The coaxial arrangement facilitates movements of the nozzle and beam in complicated patterns and ensures simultaneous application of the extrudable material and the laser beam.
