Patent CA-2221007-A1 (CA)
Inventor: ORTIZ ERNEST ALBERT
IPC: B26B21/52
Filed: 1997-11-13
Abstract: A razor which actively flexes  at least one,  and preferably a  plurality  of  skin-engaging  elements  during shaving  to  follow  the  contours  of  a  skin  surface.  One preferred razor comprises a support and a pair of rotating pivots movably connected to the support.  Each rotating pivot contacts separate portions of a razor head.   Shaving forces exerted on a first razor head portion in a first direction will cause the rotating pivot to move a second razor head portion in a second direction which is different from the first direction.  The razor also comprises means for biasing the  rotating  pivots  to  a  neutral  position.     In  one embodiment, the support comprises a pivot assembly to which the rotating pivots are connected thereby providing another degree of movement to the rotating pivots relative to the support.

Filed: 1997-04-23
Abstract: The method generally includes the steps of receiving (201) a message (100) comprising a message indicator (101) and a plurality of encrypted blocks (103 through 111). When at least one block of the plurality of encrypted blocks is received with error, a second message is transmitted (215), which second message requests a retransmission of the at least one block. Upon receiving the retransmission of the at least one block without error, a keystream is generated (219) from the message indicator and the at least one block is decrypted using the keystream.

Title: Medical suite and x-ray imaging apparatus
Inventor: GREEN MARTIN STEPHEN
IPC: A61B6/03
Filed: 1998-02-12
Abstract: A medical suite includes a room divided into two sections with a moveable door therebetween. A first x-ray imaging apparatus is positioned in one section in a mono-planar configuration. A second x-ray imaging apparatus is translatable between a first position in the other section in a mono-planar configuration and a second position in the one section in a bi-planar configuration with the first x-ray imaging apparatus.      Consequently, facility cost is reduced over that of separate mono-planar and bi-planar arrangements while patient throughput is maintained.      Reconfiguration to bi-planar can be accomplished during patient preparation thereby not impacting throughput.

Title: Couteau pliant a platines et a triple verrous, entierement demontable
Inventor: GIORGIFANI ANDRE LOUIS
IPC: B26B5/00
Filed: 1998-09-17
Abstract: Armurier depuis 10 ans j'ai constaté que les couteaux pliants existants sur le marché utilisent généralement un principe d'ouverture et de fermeture de la lame qui consiste en un seul point de blocage à l'ouverture le plus souvent actionné par un ressort. A la fermeture ce même ressort pousse la lame sens retenue jusqu'à son logement dans la poignée. Mon brevet concerne un nouveau système de blocage de la lame tant à l'ouverture qu'à la fermeture. Ce couteau a comme caractéristiques techniques trois systèmes de blocage de la lame, qui renforcent la sécurité de son utilisation. Les deux blocages de la lame en position ouverte sont actionnés par une clef et son pied de clef. Le blocage à la fermeture permettant de maintenir solidement la lame dans son logement, est situé sur un mécanisme amovible. A noter qu'en fin de course de la lame en fermeture l'utilisateur doit exercer une légère pression jusqu'à son point de blocage. Cette pression engendrée par un poussoir-ressort logé dans la poignée a pour but d'éliminer tout jeu de la lame en position fermée. Ce couteau est entièrement et simplement démontable ce qui permet l'interchangeabilité des pièces et facilite son entretien. Mon système novateur comprenant une clef située sur le dessus du couteau, il m'a paru évident en tant qu'armurier de profession d'établir une correspondance esthétique entre mon couteau et une arme à feu. Ce rapprochement permet de comprendre rapidement que mon couteau est une arme de précision, sécuritaire et entièrement démontable.

Title: Chew toys for domestic carnivorous animals and method for making same
Inventor: SHERRILL LES R
IPC: A01K29/00
Filed: 1997-09-25
Abstract: Chew toys (10) for domestic carnivorous animals having rawhide (11) and jerky sheets or members (12). The jerky sheets (12) are wrapped in a rawhide sheet (11) by either rolling or folding. This provides an outer layer (18) of rawhide containing jerky therein. A seam (19) is created in rawhide outer layer (18) by the rolling or folding of the rawhide sheet (11). The jerky (12) preferably extends through this seam (19) to provide an initial attractive odor and taste for the dog and provide an immediate starting point for chewing. The benefits of the jerky (12) and the rawhide are maximized throughout the entire chewing process of the chew toy (10). Dogs are highly attracted to the scent and taste of jerky (12), which causes the dog to chew on the rawhide (11) for extended periods of time. This better satisfies the dog's instinctive urge to chew, channeling it in a healthy direction, while simultaneously reducing the tartar on their teeth. The jerky (12) is positioned with respect to the rawhide (11) to enable the odor and taste sensations of the jerky (12) to always be present and fresh to the dog.

Title: Treatment of neurodegenerative conditions with nimesulide
Inventor: PASINETTI GIULIO MARIA
IPC: A61P25/28
Filed: 1997-11-19
Abstract: The present invention relates to the use of nimesulide and structurally related compounds in the prevention and/or treatment of neurodegenerative conditions. It is based, at least in part, on the discovery that nimesulide exhibits a neuroprotective effect against .beta.-amyloid induced cell death.  Without being bound to any particular theory, it appears that nimesulide inhibits a non-inflammatory mechanism of neurodegeneration.
