Patent CA-2458698-A1 (CA)
Title: Improved asymmetrically accelerated vibrator for feeding materials
Inventor: JOHNSON LEROY A
IPC: F01L25/02
Filed: 2004-02-25
Abstract: An asymmetrical vibrator is provided, which is actuated by compressed air. The vibrator operates in a case, which has two bores disposed parallel on opposite sides of the casing. One of the bores is smaller than the second bore and the piston operating in the small bore is called the slow piston, since it is actuated with air to a relatively slow motion and the piston operating in the second larger bore is called the fast piston, since it is moves at a larger speed when driven directly by the compressed air. The asymmetric vibration motion can be employed to transport materials upwardly in factories and assembly stations. The air operated asymmetric vibrators need low maintenance and do not entail the spark dangers caused by the presence of electrical wiring for electrical drive motors.

Abstract: A nebulizer comprising an aerosol generator (100) and a titration mechanism (20) comprising a dosing mechanism (30), a screw assembly (50), a plunger (60) and an actuator (40), wherein the dosing mechanism is rotatably mounted in the nebulizer and the plunger is mounted in the nebulizer to travel along a longitudinal axis (62) substantially perpendicular to the plane of rotation of the dosing mechanism. The actuator is mounted to the nebulizer to travel in the direction (42) of the longitudinal axis. The screw mechanism allows the rotation of the dosing mechanism to fix a variable distance of travel of the plunger based on the selected dose, without moving the plunger longitudinally. This allows the user to verify and if necessary correct the selected dose prior to any drug being released from the vial. Operation of the actuator causes longitudinal movement, through the screw mechanism, to the plunger.

Patent CA-2493744-A1 (CA)
Inventor: SHIELDS JAMES A
IPC: H04L12/00
Filed: 2003-07-15
Abstract: A shared mesh protection scheme defines an associated protection path when a working connection is established. Both global and local protection schemes are used to provide advantages similar to ring and span protection switching in ring networks. During the global protection path definition, the corresponding protection path information is sent down to a switch card of network elements making up the protection path. Upon detection of the failure, the network elements using an overhead byte message will inform the routing source network element of the connection of the failure in the working path.  The overhead bytes used are interrupt driven bytes located in the line and path overhead of network traffic. The routing source node of the connection will then send the corresponding overhead byte messages down the protection path to provide for protection path establishment according to the preloaded data located at the switch card. Accordingly, the routing tables located at the switch cards of the network elements, set-up when the working path connections were initially established, determine this dynamically allocated protection path environment. It is noted that interrupt driven overhead bytes for network traffic are used to help provide for protection times of less than 300 msec. Local protection switching and switch selection on available local protection segments can be used instead of the global protection scheme when local protection channels are available on the local protection segments.
