Patent CA-2227225-A1 (CA)
Inventor: RAZ RYAN S
IPC: G02B21/24
Filed: 1996-07-18
Abstract: An automated focus system comprising an intelligent controlled electromechanical actuation system for manoeuvring a microscope lens. The focus system brings a stained biological material into optimal focus for image acquisition. The automated focus system is operable without human intervention and utilizes a merit function based on the "texture" of a dark stained biological material in the field of view of the microscope objective. The system utilizes a maximization procedure using a feedback technique related to the merit function in order to control the position of the objective lens. The merit function, in turn, is based on a series of calculations performed on a set of digitized images captured at different focal positions. The use of an intelligent control routine to issue instructions to the motion control system allows the device to avoid the usual focus and pitfalls associated with microscopic image capture.

Title: Method for introducing gas into a liquid
Inventor: SELINES RONALD JOSEPH
IPC: B01F5/02
Filed: 1998-03-16
Abstract: A method for introducing gas into a liquid wherein a gas stream is ejected from a lance spaced above the liquid surface and directed from the lance onto the liquid surface.  The gas retains substantially all its original jet axis velocity when it contacts the liquid surface, and substantially all of the gas penetrates the liquid surface and is introduced into the liquid. Preferably the gas stream is surrounded by a flame envelope running from the lance to the liquid surface, which shields the gas from ambient gas entrainment. The gas stream preferably forms a gas cavity within the liquid having a diameter substantially the same as the diameter of the gas stream as it is ejected from the lance.

Title: Multi-class network
Inventor: BESHAI MAGED E
IPC: H04L12/56
Filed: 1998-04-30
Abstract: A multi-class digital network is described.      The network supports a plurality of digital services using dynamically-configured service bands to support various transport modes and qualities of service. A network control element receives traffic and network state information from the nodes. The network control element maintains a network topology and uses the network topology to compute route sets for the nodes. The network control element uses the traffic information to compute network size specifications. The switching nodes use rate controllers to divide the capacity of each link among the connection classes according to rules which ensure consistent service attributes for each band across the network. The rate controllers are adapted to support different transport modes and different packet sizes so that the deconstruction and reconstruction of packets at network edge devices is eliminated. The advantage is a flexible multi-class network which dynamically reconfigures to service traffic loads as service demands fluctuate.

Filed: 1999-03-08
Abstract: A container made from a rigid, polymeric material, or from glass or metal, has a frusto-conical or cylindrical wall defining an outer thread and having an upper edge, which defines a sealing bead extending circumferentially and having a cross-section conforming to a circular arc of more than 180°. A closure made from a comparatively resilient, polymeric material has a circumferential recess adapted to receive the sealing bead with a snap fit so as to prove a liquid-tight seal. The closure has a frusto-conical or cylindrical skirt defining an inner thread. A reinforcing bead at a lower edge of the closure skirt clears the outer thread when the closure is snap-fitted or screwed onto the container and provides the closure skirt with sufficient hoop strength to prevent the inner thread from snapping upwardly past the outer thread upon relative rotation of the closure and the container to unscrew the closure from the container.

Title: Wheelchair lift platform having internal gas spring deployment from stowage position
Inventor: BUDD ALFRED L
IPC: A61G3/06
Filed: 1999-04-30
Abstract: Improvement in wheelchair lifts generally of the dual hydraulic parallelogram type employing a lever arm assembly which assists in the rotation of the platform from the stowed position to the horizontal deployed position, by providing a gas spring disposed in the lever arm assembly connected at an outboard end to the lifting mechanism link and at an inboard end to at least one of the A arm, the B arm or the common pivot pin of the lever arm assembly. The outward force of the gas spring causes the sliding shoe of the lever arm assembly to maintain contact with the outer face of the lower link of the lifting parallelogram so that upon deployment of the lift during the gravity down phase from stowed position to horizontal transfer position, the inboard end of the platform is pulled up so that it rotates smoothly and is not subjected to free fall. This lever arm follower force member can be used alone or in conjunction with a deployment assist gas spring disposed in the lifting parallelogram, alone or in combination with "reverse"  type torsion springs disposed in one or more of the common pivot in the lever arm assembly or a pivot in the lifting assembly.
