Title: Printer sheet deskewing system with automatic variable nip lateral spacing for different sheet sizes
Inventor: BENEDICT LAWRENCE R
IPC: B65H5/06
Filed: 2000-03-22
Abstract: A sheet handling system for correcting the skew and/or transverse position of sequential sheets, especially those moving in a process direction in a sheet transport path of a reproduction apparatus to be registered for image printing, of the type in which the deskewing and/or side registration is accomplished by partially rotating the sheet with a transversely spaced pair of differentially driven sheet steering nips. The effective range of sheet size capabilities of such systems may be increased without steering nip slippage or other problems by applying a control signal proportional to the width of the sheet to a system for automatically increasing or decreasing the transverse spacing between the pair of sheet steering nips, so as to provide a much wider spacing for larger sheets yet still be able to handle small sheets. This may be provided as shown by automatically engaging only a selected pair of steering nips out of a selectable plurality of different fixed position sheet steering nips and disengaging the others by lifting their idlers out of the sheet path with cams rotated by a stepper motor with a rotation controlled by the sheet width signal.

Title: Three-dimensional arrow
Inventor: DUMAS ARNAUD RIBADEAU
IPC: G06F3/0481
Filed: 2000-06-23
Abstract: A method and apparatus for guiding flight through a computer digital mockup object scene is generated on a display. A three dimensional graphical figure, such as an arrow, is formed on the display to represent a trajectory responsive to positioning of an input device. The three dimensional graphical figure is bent responsive to rotation speed of a viewpoint base; and stretched or compressed responsive to viewpoint translation speed. The visual texture of the three dimensional graphical figure can be altered to indicate an imminent collision of the viewpoint with an object in the digital mock up scene. Altering the texture can include changing the color or presenting a pattern such as a checkerboard or stripes. An imminent collision is determined by computing the viewpoint eye translation along its sight direction and testing the resulting eye position against the depth buffer. The three dimensional graphical figure can also be vibrated back and forth responsive to a collision of the viewpoint with an object in the digital mockup scene.

Abstract: Cet appareil permettant de délivrer une quantité prédéterminée de liquide (18) comprend un réservoir à liquide (12), un passage (13) pourvu d'un orifice de sortie (16) et servant à amener le liquide (18) du réservoir vers cet orifice de sortie et un dispositif de production de gaz pulsé. Cet appareil est conçu pour que le gaz pulsé expulse, par l'orifice de sortie, une quantité prédéterminée de liquide. L'orifice de sortie comporte deux ouvertures se faisant face dans le passage, le liquide étant retenu entre ces ouvertures par la tension superficielle en l'absence de flux gazeux. Lorsque l'appareil fonctionne, ce flux gazeux est dirigé sur l'une des ouvertures. On peut utiliser cet appareil pour délivrer des quantités données d'un réactif liquide et ce, dans une plage comprise entre un nanolitre et deux microlitres. La structure de la tête de distribution de cet appareil qui évite toute contamination du liquide permet d'utiliser des dispositifs se présentant sous forme d'unités jetables de faible coût de revient. Ce nouvel appareil est moins sensible à la viscosité des liquides que les appareils existant à ce jour.
Patent CA-2318714-A1 (CA)
Inventor: SAVARD DONALD D
IPC: B08B9/055
Filed: 2000-09-13
Abstract: A Expandable Jet Scraper Cup (EJSC) is a resilient member that is attached to a vessel allowing the vessel to pass through restrictions and is used for scraping the interior of a cylindrical object like a pipeline or used to propel a vessel through a pipeline. The EJSC is a disk-like resilient member 1 that is mounted on the body of a vessel. The EJSC is used to propel a vessel through a pipeline for cleaning or other activities.  The outside diameter of the EJSC is normally larger than the internal diameter of the pipe which causes the outer lip 2 to be compressed providing a seal as the vessel travels along the pipeline. As the vessel travels the outer lip 2 wears and eventually the Edison's outer lip 2 is no longer in contact with the internal pipe wall. Traditional cup design has focused on keeping the scraper lip 2 in close contact with the pipe wall so that a good seal is maintained and no fluid bypasses the vessel. When the scraper lip 2 is in close contact with the pipe wall it will also scrape debris such as wax off the interior of the pipe wall. In scraping wax off the pipewall, the wax is pushed in front of the vessel causing the wax to build up and slide under the scraper lip and as a result, an even layer of wax may be deposited along the length of the pipeline. The EJSC is designed to allow a calibrated amount of fluid to bypass the EJSC lip 2 so that wax scraped off the pipewall is jetted away. The EJSC is also designed to allow the pipeline operator to take advantage of the resiliency of the scraper cup and expand it laterally as the scraper wears down. Presently once a scraper cup is worn and does not provide an interference fit with the pipe wall it is discarded or refurbished. Refurbishment costs are about two thirds of a new cup. The EJSC can also be refurbished. The structure of the EJSC is radically different than existing scraper cups as it is designed to allow fluid to bypass between the cup lip and the pipewall jetting away wax and debris and cap be expanded. The jetting and expansion can be used individually or together.

IPC: H04B10/112
Filed: 1999-02-25
Abstract: A free-space laser communication system. The system is comprised of a large number of picocells. Each picocell comprises a base station providing conventional communication with at least one user but typically several or many users. Each base station comprises at least two laser transceivers, each transceiver having a pointing mechanism for automatic alignment. These transceivers provide communication with other base stations, relay information between other base stations or transmit information to conventional communication systems. The picocells cover relatively small geographical ranges such as about 100 meters. Applicant has demonstrated that at these distances atmospheric effects attenuating laser beams are not a serious problem. In a preferred embodiment the base stations generally comprise four laser transceivers with micro processor controlled pointing equipment which are aligned automatically to point at other base stations and an RF  transceiver to provide communication with users. The present invention is especially suited for providing a communication system, which can be almost immediately installed to compete with established local monopoly (or near monopoly) telephone systems. Systems according to the present invention can be installed within a few hours or a very few days. These systems can provide, for a local area, its first communication system, or provide communication services in a local area in the event an existing local system is damaged such as in a natural disaster or provide a quick temporary expansion of existing communication capacity.

Title: Valve collet for desmodromic engine
Inventor: PARKER JOHN
IPC: F01L3/10
Filed: 2001-02-08
Abstract: A valve collet concentrically mounted onto a circumferential groove of a valve of a desmodromic valve system for retaining a shim concentrically mounted on the valve of the desmodromic valve system, the shim having an inside surface of a given shape. The valve collet comprises an inner surface having an interlocking portion in the shape of the circumferential groove, the interlocking portion being interlocked with the circumferential groove. The valve collet further comprises an outer surface protruding away from the interlocking portion, the outer surface having a retaining portion matching the shape of the inside surface of the shim and cooperating with the same so as to have an increased contact area with the inside surface and thereby to improve retaining of the shim. Preferably, the inner surface of the valve collet comprises a securing portion extending longitudinally along the valve so as to secure mounting of the valve collet on the valve. Because of its increased contact area with the shim and because of its design, the valve collet does not quickly wear out and/or change in shape, remains properly seated in its bedded position, and thus extends the time interval allowable between regular valve adjustments.
