Title: Lordotic interbody spinal fusion implants
Inventor: MICHELSON GARY KARLIN
IPC: A61F2/30
Filed: 1996-06-06
Abstract: The present invention is directed to interbody spinal fusion implants (100) having a structural configuration that provides for the maintaining and creating of the normal anatomic angular relationship of two adjacent vertebrae (V2, V3) of the spine (S) to maintain and create spinal lordosis. The spinal fusion implants (100) of the present invention are sized to fit within the disc space created by the removal of disc material between two adjacent vertebrae (V2, V3) and conform wholly or in part to the disc space created. The spinal fusion implants (100) of the present invention have upper (112) and lower (114) surfaces that form a support structure for bearing against the end plates of the adjacent vertebrae (V2, V3). The upper (112) and lower (114) surfaces are disposed in converging angular relationship to each other such that the implants (100) of the present invention have an overall wedged shape in an elevation side view.

Patent CA-2229574-A1 (CA)
Inventor: KUCHAR GEORGE J
IPC: A01F12/52
Filed: 1998-02-12
Abstract: A combine return grain monitor for monitoring grain flow in a return grain path and for directing an electrical signal to a meter located in the cab of the combine to provide the operator with continuous visual indication of the grain being transported in the return grain path. A wedge-shaped horn is positioned on a wall of the combine just below the opening through which the return material is dropped to the return grain cross auger. Much of the tailing material falls against the outer surface of the wedge-horn before falling on through the opening onto the return grain cross auger. The wedge-horn mechanically amplifies sound as material strikes its outer surface. A microphone, located inside the wedge-horn, picks up the amplified sound of material striking the outer surface of the wedge-horn. The microphone provides an electrical signal which is directed to a meter located in the cab of the combine.

Patent CA-2230379-A1 (CA)
Inventor: AKIMOTO TAKAAKI
IPC: H04N19/89
Filed: 1997-07-04
Abstract: La présente invention concerne un système et un procédé de transmission d'images, au moyen desquels une image effective de référence reste toujours stockée dans une mémoire (de trames), même quand l'arrivée d'un signal d'un côté d'émission émetteur d'images en provenance d'un côté de réception d'images est retardée ou que se produit une erreur dans un signal de compte-rendu d'erreur de réception. Selon le procédé, l'écriture des données d'image codées dans une section de la mémoire est commandée à partir du contenu du signal reçu depuis le côté récepteur d'images. Cette commande comporte une estimation pour savoir si de nouvelles données doivent être écrites ou non, une détermination de la position d'écriture dans la section de mémoire et un éventuel effacement des données déjà enregistrées dans la section de mémoire. Il est préférable d'effacer de la section de la mémoire les images de référence plus anciennes que celles qui correspondent aux dernières données d'image codées correctement reçues ainsi que l'image de référence correspondant aux données d'image codées ayant contenu un compte-rendu de réception d'erreur signalé par le récepteur d'image, ceci afin de réduire le volume de la section de mémoire.
Patent CA-2231247-A1 (CA)
Title: Sterilizer testing systems
Inventor: KIRK BRIAN
IPC: A61L2/28
Filed: 1996-10-07
Abstract: A sterilant challenge device (50), for use in testing the efficiency of the air removal stage of a sterilization cycle in a sterilizer, includes a tube (2) of thermally-insulating material, the bore of which is closed at one end (52) and open at the other for the entry of sterilant. A plurality of thermally-conductive masses (51) are located around the tube (2) and thermallyseparated from one another by air gaps (59), and a temperature sensor is located in an opening (61) in one of the masses adjacent the closed end of the tube. An outer casing (25) defines an air space around the thermallyconductive masses and thermally insulates the masses from the heat in the sterilizer. When the challenge device is located in a sterilizer, the penetration of sterilant along the bore of the tube (2) during a sterilization cycle, is inhibited by the accumulation of air and/or non-condensable gas within the bore resulting from the condensation of moisture on the walls of the bore. By measuring the temperature in a thermally-conductive mass (51) adjacent the closed end of the tube (2), the presence of sterilant in the adjacent region of the bore of the tube can be detected.

IPC: A63J17/00
Filed: 1998-09-03
Abstract: In a PLD (personal lighting device), the circuit is known to coherently react to the tempo, frequency and amplitude of the immediate audible environment. The circuit will operate with equal functionality in both normal conversation sound levels and loud level sound environments such as nightclubs or discos by selectively choosing the dominant tones and beats as a basis for output. This action is accomplished by the combination of the three different functional blocks within the circuit, the amplifier front-end, the CPU stage, and the output stage. All three blocks working together will result in an electronically operated output which will represent the rhythm of the music in the immediate environment. Typical portable battery applications for this circuit will include music responsive jewelry, Christmas ornaments, clothing, shoes, party lighting and toys. The PLD circuit is comprised of both electronic hardware and software, and therefore is related to the technical field of electronics.

Patent CA-2248510-A1 (CA)
Inventor: BEAUPLAN BERNARD
IPC: E03C1/044
Filed: 1998-09-29
Abstract: Jusqu'ici, pour obtenir de l'eau bouillie potable, il faut faire chauffer de l'eau dans un récipient jusqu'à ce que l'eau bouille pendant 10 à 15 minutes. Dans la présente invention, une spirale de tuyau peint en noir, enroulée en forme de cône et placée dans une boîte noire solaire est installée sur la ligne d'approvisionnement en eau, et un dispositif de commande des vannes de remplissage et de vidange de la spirale permet d'obtenir de façon automatique et continue de l'eau bouillie potable lorsque la spirale est chauffée suffisamment et que la pression de la vapeur produite traverse un clapet de retenue (check-valve) et une valve de surpression à bascule (snap-open valve) et actionne un cylindre activateur dont le piston fait fermer la vanne de remplissage avant de faire ouvrir la vanne de vidange d'eau bouillie potable de la spirale, empêchant ainsi la contamination de l'eau potable par l'eau de remplissage. Une vanne de décompression laisse s'écouler la pression, ce qui permet au piston du cylindre par l'intermédiaire de son ressort de rappel de revenir à la position de départ c'est-à-dire de fermer la vanne de vidange avant d'ouvrir la vanne de remplissage lorsque l'eau potable a fini de s'écouler. Un clapet de retenue (check-valve) monté en amont de la vanne de remplissage retient l'eau dans la spirale lorsque celle-ci est remplie. Pour le fonctionnement semi-automatique de l'appareil, la valve de surpression à bascule est remplacée par une vanne se refermant par un ressort que l'utilisateur actionne pour envoyer la vapeur sous pression au cylindre. Un sifflet actionné par une valve de surpression ordinaire, tous deux montés sur une dérivation du circuit de vapeur, avertit l'utilisateur que l'eau a bouilli suffisamment pour être potable. Un tel appareil monté sur une ligne d'approvisionnement en eau permet d'obtenir de l'eau bouillie potable de façon semi-automatique ou automatique et continue en chauffant tout simplement la spirale.
