Patent CA-2044077-C (CA)
Title: Chemical treatment of an infectious waste
Inventor: MEIJER ROBERT S
IPC: A61B50/39
Filed: 1991-06-07
Granted: 1997-10-07
Abstract: An infectious waste, a solid chlorite salt, a solid acid and a preheated aqueous solvent are mixed in a treatment volume.  At least a portion of the chlorite salt and acid is dissolved in the preheated aqueous solvent incident to mixing and is reacted to form a treatment solution containing a chlorine dioxide disinfectant and a byproduct acid salt.  The infectious waste is contacted with the chlorine dioxide in the treatment solution which attacks and destroys the infectious constituents of the waste, thereby decontaminating the waste.      Upon dewatering, the decontaminated waste is suitable for landfilling.  Process control is exercised by controlling the temperature of the aqueous solvent.  A solvent temperature is selected  which  optimizes  both  the  chlorine  dioxide concentration in the treatment solution and the reactivity of the  chlorine  dioxide  with  the  infectious  constituents.          Continuous monitoring of the chlorine dioxide concentration in the treatment solution enables adjustment of the solvent preheat temperature to optimal values in accordance with the dynamics of the treatment system.

Granted: 1999-11-02
Abstract: Le réacteur refroidi décrit, qui est conçu pour la transformation catalytique exothermique de substances gazeuses, par exemple pour la synthèse oxo, pour la transformation d'hydrogène et d'azote en ammoniac et pour la réaction d'oxydes de carbone avec de l'hydrogène pour former du méthanol, comprend une coquille de pression cylindrique (10), un organe distributeur (34) pour le gaz de synthèse, au moins une feuille en tube (30) et un ou plusieurs lits catalytiques (20) pourvus de tubes de refroidissement (38) servant au refroidissement indirect du gaz de réaction. Chaque tube de refroidissement (38) se compose d'un tube externe (4) comportant une paroi externe d'échange thermique (7). Ce tube externe entoure un tube interne (2), par rapport auquel il est coaxial, et définit par conséquent un espace annulaire dont la paroi interne présente des trous (8) destinés à diriger le courant du gaz de refroidissement, qui peut se composer de composants du gaz de synthèse ou contenir des composants de ce gaz de synthèse, dans l'espace annulaire et le long de la paroi d'échange thermique. On obtient ainsi une égalisation très rapide des différences de températures dans le lit catalytique ce qui améliore le rendement et permet par conséquent de diminuer la quantité de substance catalytique pour un processus donné.

Granted: 2002-11-19
Abstract: A balancing arrangement for a rotating member, especially for a hollow shaft made from lightweight metal, in which a counterweight of predetermined size and weight is affixed onto the external surfaces of the rotating member in predetermined position by the use of a clamping band made from a material normally devoid of any significant elastic stretchability. A plastically deformable ear structure is provided in the clamp structure for tightening the clamping band which includes two generally outwardly extending leg portions interconnected by a bridging portion that includes downwardly bent tab-like members along the longitudinal sides of the bridging portion to act as ramp surfaces and reinforcing elements for the ear structure. The counterweight is thereby connected with the clamping band in one place by spot-welding, particularly, when both clamping band and counterweight are made of stainless steel.

Title: Reconditioning method for a non-acidic catalyst used in a high severity process for dehydrogenation of light hydrocarbons
Inventor: FETTIS MICHAEL E
IPC: B01J23/96
Filed: 1992-01-28
Granted: 1997-11-18
Abstract: A high severity process for the dehydrogenation of a hydrocarbon selected from the group consisting of propane and butane in the presence of a catalyst comprising platinum and a non-acidic carrier material is substantially improved by periodically reconditioning the resulting coke-deactivated catalyst particles containing platinum by moving the catalyst particles through a combustion zone, a drying zon, a re-dispersion zone and a reduction zone. Dryingof the catalyst particles immediately after the combustion of coke substantiallyimproves the operation of a platinum re-dispersion zone. The lower moisture content in the re-dispersion zone allows the equilibrium reaction between hydrogen chloride and oxygen on the one hand, and water and chlorine on the other hand to be shifted to the production of chlorine. This shift of the equilibrium reaction can be further improved by maintaining an oxygen-enriched environment within the platinum re-dispersion zone. The use of a much lower chloride concentration in the re-dispersion zone reduces the emissions of hydrogen chloride from the regeneration zone.

Title: Penile implant with lengthening cylinder
Inventor: COWAN TIMOTHY
IPC: A61F2/26
Filed: 1992-07-22
Granted: 2002-10-01
Abstract: A penile prosthesis with a two piece inflatable cylinder that provides significant lengthwise expansion of a male penis. The cylinder has an inflatable bellows attached to an inflatable member and a sheath that extends from a base member. The bellows is attached to the base member and the sheath is connected to the inflatable member, such that the sheath will stretch when the bellows is inflated. The sheath surrounds the bellows. The sheath is constructed from an elastic material that can expand up to 100% of its original length. The inflatable member and bellows are connected to a pump which transfers fluid between a reservoir and the cylinder. When fluid is pumped into the cylinder, the bellows and inflatable member are inflated and the sheath is expanded, allowing the inflatable member to move into an elongated position. When the cylinder is inflated the sheath is in tension, wherein the sheath will pull the inflatable member back into a compact position when the bellows is deflated.

Title: Method for control of flow cytometer having vacuum fluidics
Inventor: NORTH HOWARD JR
IPC: G01N15/14
Filed: 1993-11-26
Granted: 1998-09-15
Abstract: The present invention relates to a system for controlling the movement or transport of objects such as cells and other particles in a moving liquid stream.  More particularly the invention relates to a system including a vacuum pump which pulls the sheath fluid from an open supply reservoir through a flow cell assembly where cell analysis occurs and discharges the flow cell effluent to an open waste reservoir.  A pressure drop is created through the conduit leading from the supply reservoir to the flow cell which aspirates the cell suspension from an open sample vessel into and through the flow cell.          The vacuum is regulated by controlling the electric power applied to the vacuum pump motor.  Starting, stopping, reverse flushing,  and  draining  of  the  flow  cell  assembly  are controlled by programming the operation of four electric solenoid valves in fluid communication with the flow cell inlet and outlet passages, the operation of a reverse flush pump and, the operation of an electrically controlled tube lifter.  A deaerator is provided to remove some of the air dissolved in the sheath fluid provided to the flow cell assembly to prevent the release of air and formation of adherent air bubbles in sensitive areas of the flow cell assembly.

Abstract: A locking arrangement is provided for releasably locking door panels made of flexible material. The locking arrangement is adapted to be used on door panels of conventional vehicle shelters. The locking arrangement comprises a pair of generally hook-shaped locking members attached to the inner peripheral edges of the door panels.
