Patent CA-2409112-A1 (CA)
Title: Energy absorber
Inventor: RENTON JULIAN
IPC: E04G21/32
Filed: 2001-05-16
Abstract: An energy absorber comprises a helically coiled stores of at least partially yielding material that is drawn over a roller, or two rollers on perpendicular rotational axes, and securely fixed to a base that is attached to fragile structure such as a roof so that when an external force of sufficient size is applied to the roller or rollers through a connecting attachment eye the coil together with roller or rollers moves away from the attachment to the base whilst the coiled material is deployed over the roller or rollers. The absorber may be housed in a casing that is fixed to the base such that the strength of the fixing to the base is sufficient to withstand a pre-determined load after which the fixing fails and the housing moves with the coiled store providing protection for both the coiled store and fragile structure.

Patent CA-2418699-A1 (CA)
Inventor: RADEN EDWARD A
IPC: F16J15/08
Filed: 2003-02-10
Abstract: A cylinder head gasket has a multi-layered steel body that includes a unitary metallic stopper layer interposed between beaded outer layers. The interposed stopper layer has an asymmetrically formed bead defining at least one raised structure that circumferentially and closely surrounds a combustion aperture. Specifically, the bead defines a trough having a series of variations of thickness or widths about its circumferential dimension. An epoxy resin material substantially fills the volume of the trough about its circumferential extent, irrespective of the variable trough depth or width. In the disclosed embodiment, a metal/epoxy hard coating material is placed in and cured in the trough. To the extent that the trough has a varying height or width about its circumference, the hard coating also has a varying height or width about the circumference of the hard coating-filled bead, so as to provide a substantially uniform sealing pressure under predetermined variable conditions including bore distortion and machining tolerances.

IPC: A61M1/28

Abstract: Même si le glucose a été principalement utilisé en dialyse péritonéale pour traiter une insuffisance rénale, il apparaît que les protéines subissent une réticulation due à l'oxydation et à la dénaturation du glucose, ce qui entraîne un durcissement du tissu péritonéal et empêche de poursuivre la dialyse péritonéale. Afin de résoudre ce problème, on met en oeuvre des dialysats péritonéaux qui contiennent un inhibiteur de réticulation de protéine ou un agent qui dissocie la réticulation des protéines une fois qu'elle est réalisée. Tout comme l'inhibiteur de réticulation de protéine ou l'agent qui dissocie la réticulation des protéines une fois qu'elle est réalisée, il est efficace d'utiliser des agents de réduction ou des antioxydants. Ces dialysats péritonéaux sont préparés par stérilisation de dialysats péritonéaux à une pression et une température élevées, avant d'ajouter le(s) inhibiteur(s), puis par stérilisation individuelle du/des inhibiteur(s) et par ajout de ceux-ci.

Title: Pull out spray head with single-button mode selector
Inventor: MALEK MICHAEL L
IPC: B05B1/16
Filed: 2003-10-22
Abstract: A spray head for a faucet or the like has a wand body defining a flow path from an inlet to first and second outlets. Diverter seats are provided so a face seal on a diverter spool can direct flow to the first or second outlet. The spool is positioned by a trigger acting on cam surfaces formed on a toggle. A spring biases the toggle to one of two stable states. Movement of the spool by the trigger causes the toggle to change states so subsequent actuation of the trigger causes the spool to move in the opposite direction. The wand body also has a pause button that reciprocates in a chamber that is part of the flow path. The chamber includes a valve seat and the pause button has a spool having a face seal that is engageable with the valve seat to shut off flow through the spray head. A return spring causes separation of the pause button's face seal upon release of pressure on the pause button. The pause button's seals in the chamber are arranged to have equal diameters and thus provide balanced hydraulic forces on the spool.
