Abstract: An apparatus is provided for effecting the formation of a packaged food product with the food being contained within a receptacle having a cover adhered to the receptacle. Prior to securing the cover to the receptacle, the surface that is to be sealed to the cover is cleaned by wiping with towel material. The towel material is advanced from a supply to a cleaning position to wipe a cover engaging surface to remove at least a portion of contaminants or foreign material present on the container, thereby improving adhesion of the cover to the receptacle. Towel material can be advanced from time to time from the supply to a take-up mechanism to present clean or fresh towel material at predetermined intervals.

Patent CA-2416241-A1 (CA)
Inventor: COMEAU JEAN-GUY
IPC: B65B69/00
Filed: 2003-01-14
Abstract: The invention provides a device for use in the extraction of bottles or the like from cartons travelling in a stream on a conveyor, each carton having a bottom wall and associated side walls. The device has a saw blade adapted to extend across the conveyor to cut the associated side walls just above the base which is thereby severed. The saw blade is vertically adjustable so as to accommodate cartons having bases of different thickness' and thereby ensure avoidance of damage to the bottles sitting on said bottom wall. A sensor positioned upstream of said blade determines the vertical position required for each passing carton and transmits a signal which results in the blade being positioned as required.

Title: Procede et dispositif servant a indiquer des impacts
Inventor: ISOZ PETER
IPC: F41G3/26
Filed: 2002-03-19
Abstract: L'invention concerne un procédé et un dispositif servant à indiquer qu'une cible (1), telle qu'un véhicule, a été touchée. La cible comporte une information concernant l'effet de l'arme et une source lumineuse indique un impact. On peut transférer cette information par transmission électromagnétique directe, par exemple, par radio ou au moyen d'une ou de plusieurs bandes (9-11) pourvues de détecteurs (13), disposées sur la cible (1). Dans ce dernier cas, ces détecteurs détectent le rayonnement électromagnétique d'éclairage incident et une source lumineuse indique un impact quand ce rayonnement incident répond à des critères de détection déterminés. Selon l'invention, la source lumineuse est montée directement sur une ou plusieurs bandes (12) qui, dans ce cas, peuvent être les mêmes bandes que les bandes de détection et consistent en des points lumineux répartis se présentant, de préférence, sous la forme de diodes luminescentes (14). Ceci permet d'obtenir une solution protégée et intégrée n'exerçant qu'un effet limité sur la forme de la cible.

Abstract: L'invention se rapporte à un dispositif de stimulation de tissus implantables comprenant un élément de support d'électrode allongée (11) ayant une pluralité d'électrodes. Ces dernières sont alignées de préférence sur l'élément de support (11) et sont conçues pour appliquer une stimulation tissulaire présélectionnée sur la cochlée. L'élément de support (11) est préformé à partir d'une silicone biocompatible flexible et élastique et s'étend d'une extrémité distale (12) vers un élément de butée (13). L'élément de support (11) est destiné à être inséré hors d'une lumière au sein de la cochlée d'un patient. L'élément de support (11) est spécialement indiqué pour une implantation dans la fente (21) venant entre le ligament spiral (22) et l'endoste (23) de la paroi latérale de cochlée (20). Il s'agit d'un emplacement relativement différent de l'emplacement normal de la matrice d'électrode d'implant cochléaire de la rampe tympanique (24) de la cochlée (20). La mise en place de l'élément de support (11) est sensée éviter toute percée des conduits internes de la cochlée (20), notamment de la rampe tympanique (24) et de la rampe vestibulaire (25) de manière que le comportement hydrodynamique normal de la cochlée (20) ne soit pas affecté par un dispositif intrusif. Sans affecter le comportement hydrodynamique normal de la cochlée (20), l'utilisation de l'élément de support (11) optimise la possibilité de préserver également toute faculté auditive du patient qu'offre la cochlée (20). L'utilisation du dispositif dans un système permettant de masquer ou traiter les symptômes des acouphènes fait également l'objet de cette invention.

Abstract: A multichannel hearing aid (20) comprises at least one frequency channel having a compressor (38) with a compression threshold at an output level bel ow the hearing threshold and an attack time above 0.5 seconds whereby hearing o f a sudden sound in a stationary sound environment is facilitated. With this compressor, the amplification of low signal levels may be increased compared to the prior art, as the compressor kicks in to generally suppress steady noises. The gain may generally be increased as high as feasible in view of t he microphone baseline noise, which should preferably be kept below the hearing threshold. Thus the user of the hearing aid will generally have the option o f a higher gain of low level sounds than generally feasible with prior art hearing aids.
