Patent CA-2128140-A1 (CA)
Inventor: CHARBONNEAU PIERRE
IPC: A61L9/16
Filed: 1994-07-13
Abstract: La présente invention est un système de stérilisation constitué d'un stérilisateur et d'un échangeur-récupérateur d'énergie qui propose une solution aux problèmes actuels inhérents à l'utilisation d'instruments pneumatiques et d'appareils respiratoires dans les domaines industriels et médicaux. En effet, la qualité de l'air comprimé consommé directement ou indirectement par l'humain est tributaire de l'atmosphère ambiante où le compresseur se trouve et de la nature même du réservoir du compresseur, qui constitue un incubateur idéal pour les micro-organismes pathogènes s'y trouvant. La présente invention est un appareil stérilisateur récupérateur d'énergie. L'air comprimé vicié passe à une pression moyenne de 100 à 150 Ibs/po2 et à un débit d'approximativement 100 cfm dans l'échangeur par une tubulure métallique d'entrée, enroulée en spirale, où il est préchauffé, puis circule dans le stérilisateur par le biais d'une tubulure métallique munie de chicanes internes, enroulée en double spirale à l'intérieur d'un élément électrique qui la chauffe à 400 .degree.C. L'air comprimé stérile repasse dans l'échangeur (avant de se diriger vers les instruments pneumatiques) par le biais d'une tubulure métallique de sortie enroulée en spirale autour de la tubulure d'entrée à laquelle il communique sa chaleur. Les deux montages (échangeur, stérilisateur) sont trempés individuellement dans du métal liquide et enfermés dans de la laine de céramique qui sert d'isolant thermique.

Patent CA-2130945-A1 (CA)
Title: Fluid Flow Meter
Inventor: INGMAN DOV
IPC: G01F3/20
Filed: 1994-08-26
Abstract: The fluid flow meter includes a flexible membrane clamped between upstream and downstream centering springs to enhance membrane behavior and extend the fluid flow measurement range by automatically adaptively moving the apparent clamping points in response to flow rate. Adaptation of the clamping span alters the relative effective excess membrane length within the clamping span to adapt membrane behavior to flow rate.  The upstream centering spring includes a long leaf spring pair cantilevered into the clamping span from the clamping region.  The long leaf spring pair is sandwiched within a shorter leaf spring pair active at higher flow rates and formed as part of a guide extending to the chamber surface.  The membrane ends are narrowed upstream and downstream of the clamping span to reduce flutter while the upstream intake is split into even laminar flows. The fluid direction is substantially changed at the outlet to minimize membrane distortion.

Patent CA-2148631-A1 (CA)
Inventor: HILDIN JOHN J
IPC: H04N7/14
Filed: 1995-05-04
Abstract: A voice-following video system for dynamically capturing the view of an active speaker includes a video camera, a position control system for the video camera, and one or more voice-activated emitters. A voice-activated emitter is associated with each potential speaker. As a person talks, the associated voice-activated emitter transmits a position signal. The position control system uses the position signal as a beacon to determine the location of the active speaker. The position control system then adjusts the pan and/or tilt of the video camera to bring the active speaker into the field of view and tracks that person's movements. In this manner, as one person stops speaking and another starts, the video camera is automatically repositioned, capturing the view of the active speaker.

Inventor: BLASE JAMES LEONARD
IPC: F16H57/08
Filed: 1995-09-18
Abstract: An improved planet bearing and gear assembly for the carrier of a speed increasing planetary gear train for driving a diesel engine turbocharger or the like includes an enlarged diameter gear bore and associated bearing outer diameter for lightening the gear and increasing the bearing area to at least 50 percent and preferably more than 65 percent greater than those of the bearing inner wall and the outer diameter of an associated support pin.  Self-cleaning of unfiltered dirt particles in the engine lubricating oil is provided by dirt expulsion passages formed by flats at the edges of an oil supply groove in the planet bearing while operation with entrained dirt particles capable of passing through the engine lubricating oil filters is improved by increased oil film thickness resulting from reduced bearing loads due to reduction of mass of the planet gears and increased bearing surface.  Circumferential oil grooves in the inner surface help cool the bearing prior to delivery to an oil supply groove which is configured with a flat floor toward one end adjacent oil supply holes and an arcuate floor on the other end to improve manufacturing accuracy and convenience.

A manually adjustable tensioner allows for adjusting the stretch of the wrapping film on the package, while the film wrap supply may be adjusted vertically to permit wrapping the package over its entire vertical dimension regardless of the width of the roll of film wrap.  A foot control allows an operator of the apparatus to rotate the deck and the package being wrapped while vertically moving the film wrap supply roll to fully enclose the package within the wrapping film.
Patent CA-2161571-A1 (CA)
Inventor: LOWE TERRY LEE
IPC: A01B71/02
Filed: 1995-10-27
Abstract: A series of notches are provided in the upright plates on one end of a parallel bar linkage connecting a cultivator rig or planter assembly to a tool bar.  Coil springs are tensioned between the opposite end of the linkage and a rod and trunnion assembly that fits into the series of notches.  The coil springs maintain the rod and trunnion in a selected set of notches.  A handle on the rod allows the operator to walk the rod and trunnion assembly up and down the series of notches to select a different set of notches and thereby incrementally adjust the down pressure to a known value or setting.  When the tool bar is raised to a transport position and the linkage pivots downwardly to a lowermost position, the spring is stretched only slightly so that down pressure adjustments can be made easily using only the handle on the rod.
