Patent CA-2296833-A1 (CA)
Title: Turbo fan engine nacelle exhaust system with concave primary nozzle plug
Inventor: GALLY THOMAS A
IPC: F02K1/44
Filed: 2000-01-24
Abstract: A turbo fan engine nacelle houses an engine which forces engine exhaust through a primary nozzle and a fan nozzle positioned along a common central axis. The primary nozzle is bordered interiorly by a primary nozzle plug and bordered exteriorly by a primary nozzle sleeve. The fan nozzle is bordered interiorly by a core cowl and bordered exteriorly by a fan nozzle sleeve. The primary nozzle plug includes a generally cone shaped outer surface which is concave when viewed in side elevation. The concave outer surface has a radius of curvature (R c).  The core cowl has a distal end which is radially spaced from the outer surface of the primary plug by a distance (.DELTA.H) in a direction perpendicular to the central axis. The primary nozzle plug and core cowl define a ratio R c/.DELTA.H between approximately 14 and 18. The distal end of the core cowl has a core cowl radius R p with respect to the central axis. A discharge end of the fan nozzle sleeve has a fan nozzle sleeve radius R f, wherein a ratio R p/R f is between approximately 0.4 and 0.6. The outer surface of the primary plug forms a primary plug angle ~p between approximately 13° and 19° with respect to the central axis at the primary nozzle exit. The proper scaling of these key dimensions thereby defines a primary nozzle which reduces the shock associated noise of the turbo fan engine.

Patent CA-2318107-A1 (CA)
Inventor: JENKINS WILLIAM M
IPC: G09B7/04
Filed: 1999-01-22
Abstract: Computer-implemented training exercises present stimuli to a user and receive responses by the user to the stimuli. The stimuli are specifically selected to challenge and improve cognitive ability of the user, e.g., the ability to perceive and understand spoken language. As a result, the stimuli cannot be changed or adapted to motivate the user through entertainment. Motivation is therefore provided by periodic reward animations (1214) which include persistent plots and characters. Progress indicators represent progress toward reward animations and represent such progression with smooth, entertaining progress animations. Randomly appearing animations and variations in rewards and immediate feedback add to the surprise and curiosity of the user and motivate further correct responses to see further random animations and variations. Progress indicators also represent a relation between the number of steps taking toward completion of a task and a maximum number of steps which should be needed to complete the task. Context is changed at achievement milestones to indicate progress to the user.
