Title: Systeme de traitement secondaire compact d'eaux usees
Inventor: BUTTS NICHOLAS E
IPC: C02F3/04
Filed: 2001-08-28
Abstract: Cuve de traitement (1) pour le traitement secondaire d'eaux usées, qui permet les processus d'aération, de nitrification et de dénitrification dans un seule structure, pour laquelle une seule pompe (26) à effluent de faible puissance est la seule partie mobile. Dans la cuve de traitement (1), les eaux usées sont soumises à deux traitements biologiques séparés, dans deux chambres séparées et dans des conditions différentes. Le premier traitement biologique est effectué dans des conditions anoxiques dans un tuyau hélicoïdal (3). Les conditions anoxiques sont garanties par le fait que le tuyau hélicoïdal (3) est maintenu plein à tout instant. L'axe de ce tuyau hélicoïdal (3) est vertical et la pompe refoule le flux de fluide vers le haut par le tuyau. Le second traitement biologique est effectué dans des conditions aérobies dans un filtre (8) à écoulement goutte à goutte. Dans un mode de réalisation préféré, un tuyau hélicoïdal (3) soudé est utilisé à la fois pour fournir les conditions anoxiques et pour fournir une cuve contenant le filtre (8) à écoulement goutte à goutte. La cuve de traitement secondaire est généralement utilisée en tant que partie d'un système de traitement d'eaux usées brutes comportant une boucle de recyclage qui garantit la présence constante d'un flux de liquide dans la cuve de traitement, même si l'entrée d'eaux usées brutes dans le système est interrompue.

Patent CA-2005095-A1 (CA)
Inventor: LONN ALAN H
IPC: E02F9/28
Filed: 1989-12-11
Abstract: Ground engaging bits used in abrasive road grading applications utilizing carbide inserts brazed to the leading face of the steel tip are beneficial on motor grader blades.  Commercial road grading bit assemblies use consistent thickness, rectangular carbide inserts brazed to the leading edge of the steel tip.  Due to wear and high residual stresses imparted upon the insert from the brazing operation, premature cracking and breaking of the carbide inserts occur.  The subject bit arrangement utilizes a carbide insert with a flat rectangular cutting face of non-constant thickness brazed to a leading edge of a steel body.  The carbide insert has a thickness that increases from the top of the carbide insert and reaches a maximum at the bottom of the steel body, where bit wear is the greatest.  The increasing thickness of the carbide tip extends bit life over the current rectangular design and allows for a more efficient and economical use of the carbide.  This design also reduces the residual stresses in the carbide insert which normally occur during the brazing operation, thus substantially reducing cracking and breaking, and further extending bit life.

Title: Hydraulic buoyancy force suit
Inventor: WURST STEPHEN G
IPC: B64D10/00
Filed: 1989-12-22
Abstract: A method and apparatus for maintaining useful conciousness and reducing the risk of injury for a subject exposed to high levels of acceleration while in a vehicle.  A buoyancy force suit is provided for supporting the subject with a buoyancy force.          The buoyancy force suit includes at least two layers of flexible material, each layer being relatively impermeable to a substantially incompressible fluid locatable in a space between the layers.  The suit fits over substantially the entire subject, including the subject's neck.  A fluid reservoir is provided for maintaining a constant fluid level within the buoyancy force suit during acceleration.  The fluid reservoir is supported at substantially the subject's eye level for maintaining an optimal fluid pressure gradient for ensuring an efficient blood supply to the subject's brain.  Means are provided for securely suspending the buoyancy suit within the vehicle.  A regulator is also provided for compensating for any increased pressure exerted on the subject's rib case as d result of the force suit.  The force suit provides a balance counterpressure to the force of acceleration thereby reducing distension in the subject's blood vessels and the pooling of blood.
