Title: Optical ip packet switch
Inventor: WATANABE ATSUSHI
IPC: H04B10/299
Filed: 2000-08-11
Abstract: IP packet transmission equipment in a network containing backbone and branch transmission lines and transmits optical path signals between two nodes via logically defined optical paths. Wavelength demultiplexing means demultiplexes a wavelength-multiplexed signal from each backbone transmission line to form optical path signals. IP packet routing means converts a transmission signal from each branch transmission line to IP packets for outputting the destination corresponding to routes. IP/optical path converting means converts the IP packets to optical path signals. Optical path switching means cross-connects optical path signals from the wavelength demultiplexing means and the IP/optical path converting means to destination output routes. Optical path multiplexing means wavelength multiplexes optical path signals on predetermined routes to generate an output wavelength-multiplexed signal which is output to each backbone transmission line. Optical path signals contain an optical path payload for storing the IP packet to generate a payload signal.

Abstract: A labeler for objects, such as fruit or vegetables, has a pickup head that includes a firing piston, and a larger piston that is coupled to the firing piston. The pickup head, along with other pickup heads, are provided on an assembly that rotates the heads in a circular manner. When each pickup head is at the 6 o'clock position, a burst of air pressure is provided to the firing piston, thereby causing it to fire and to cause the larger piston to move in an outward direction. This causes the pickup head to extend fully, to thereby cause a label positioned on an applicator at a distal end of the pickup head to contact an object and thereby apply the label to the object. At other positions besides the 6 o'clock position, a vacuum source provides a vacuum to the pickup heads, thereby maintaining the pickup heads in a fully retracted position, as well as providing a way for keeping the label on the applicator of the pickup head while the pickup head is rotating.

Filed: 1999-03-22
Abstract: L'invention vise à permettre, dans des couvercles de fermeture, un abaissement d'une zone d'ouverture et l'obtention d'une résistance à la compression supérieure, sans provoquer pour autant des déformations mécaniques par flambage de la zone abaissée lors de l'application d'une compression étendue, par le dessous, à des pressions élevées. A cet effet, il est prévu un couvercle de fermeture en tôle pour boîtes-boissons, comportant de l'intérieur vers l'extérieur, une surface de couvercle (10), une rainure périphérique (20) et une collerette sertie (21). Au niveau de la surface du couvercle, une zone plane (40) adaptée à la forme d'une languette de préhension (9) et d'une zone d'ouverture (8) est abaissée par rapport au plan de la surface de couvercle (10). Cette zone plane (40) présente des zones marginales longues (42, 43) et courtes (45, 46) qui la délimitent par rapport au reste non abaissé. Au moins une des zones marginales courtes (45) remonte légèrement (.alpha.) du plan de la zone plane abaissée (40) vers le plan de la surface de couvercle (10) situé plus haut, de façon à créer une zone de transition déformable élastiquement lors de l'application d'une compression étendue, par le côté inférieur du couvercle.

Patent CA-2327897-A1 (CA)
Title: Spill proof snack container
Inventor: VOLOSHIN CORRI
IPC: B65D25/02
Filed: 2000-12-07
Abstract: The present invention provides a spill-proof container having a two-panel cover such that an upper panel is stationary, while a lower panel is enabled for rotational motion relative to the upper panel. As each panel has an aperture in it, and the lower panel provides a device for manual actuation of the rotational motion of the lower panel relative to the upper panel, the invention enables one to reach inside of the container when the lower aperture is positioned by the rotative motion adjacent to the upper aperture. Therefore, the food is held fresh and protected from exposure to the undesirable moisture or dryness of the fresh air, while it is easily accessible without removal of the container's cover. This objective is further enhanced by a resilient, snap-action engagement of an L-shaped annular container cover rim with the top annular rim of the container. Additionally, the lower panel aperture is provided with a flexible surface which is split by radial slits into flexible fingers. The flexible fingers are such that they are capable of bending into the container when a hand reaches inside of the container for food, and resiliently return to their initial planar position, automatically closing the container when the hand is removed. Consequently, no food will spill out if the containeris tilted too far or accidentally tipped over.

Title: Optical coupling
Inventor: CHENG YIHAO
IPC: G02B6/32
Filed: 2000-12-11
Abstract: The present invention relates to an optical coupling between an end of an optical fibre and an end of a lens, which provides a reliable joint with a determined spacing and angular orientation. The optical coupling permits movement of the end of the optical fibre relative to the lens in at least two alignment directions. Advantageously, the present invention permits movement of the end of the optical fibre relative to the end of the lens in a direction perpendicular to the optical axis of the lens, before the optical coupling is secured. The optical fibre within an optical fibre tube/ferrule and the lens are secured within separate sleeves and the sleeves bonded together. The end of the optical fibre and the end of the lens are optically aligned before being secured in place relative to each other. Alternatively, the invention provides similar advantages in coupling two lenses to one another via separate sleeves they are contained within
