Patent CA-2221906-C (CA)
Inventor: YEN YUNG-TSAI
IPC: G03F1/64
Filed: 1997-11-24
Granted: 2004-03-23
Abstract: One aspect of the invention comprises a method of assembling an optical pellicle including a pellicle frame and a pellicle membrane in which adhesive is first applied to the pellicle frame, and then solvent in the adhesive is permitted to evaporate. Normally the step in which solvent is permitted to evaporate involves baking the frame with the adhesive thereon at an elevated temperature. The pellicle membrane is then placed over the adhesive covered frame, and a laser is used to bond the membrane to the frame. An additional, optional step to this process involves application of the laser to the outer edge of the pellicle membrane after the membrane is mounted to the pellicle frame to trim off excess membrane.

Abstract: A platform-type wheelchair lift for mounting in the stairwell of a vehicle, suchas a bus or train. The wheelchair lift includes a platform frame that is movable from a retracted position in which it is stowed underneath the vehicle to an extended position in which it extends out from the side or back of the vehicle. A wheelchair platform is movably coupled to the platform frame by a parallelogram linkage that allows thewheelchair platform to move between a lowered and a raised position. The wheelchair platform includes foldable outer and inner wheelchair barriers that prevent a wheelchair from moving off of the wheelchair platform during operation of the wheelchair lift. The wheelchair platform also includes a mechanical ground interlock mechanism. The ground interlock mechanism is moveable between an unlocked and a locked position. The ground interlock mechanism is in an unlocked position when the wheelchair platform is touching the ground. In the unlocked position, the groundinterlock mechanism allows the outer barrier to move between an upright barrier position, and a fully extended position in which a wheelchair may be maneuvered onto or off of the wheelchair platform. When the wheelchair platform is not in contact with the ground, the ground interlock mechanism moves into a locked position in which the outer barrier is prevented from moving between the upright position and the fully extended position.

Title: Drag conveyor system for particulate material
Inventor: BAKER JON F
IPC: B65G19/22
Filed: 1998-03-16
Granted: 2004-05-25
Abstract: A drag conveyor consists of a uniquely-configured trough and correspondingly-shaped outer edges of chain-driven paddles which enable the trough construction to provides physical support for a return run of the chain. The cross-sectional shape of the trough further restricts the paddles from tending toward lifting above the trough bottom and climbing or twisting as they carry material toward the outlet end of the conveyor. The paddle shape results in a self-cleaning conveyor, even enabling handling of materials heretofore not feasible with conventional U-shaped trough conveyors. Elimination of obstructing idler sprockets and cross shafts of the prior art enables a productivity increase of as much as 15% for the same designated size of conveyor.

Title: Distortion penalty measurement technique in optical systems based on signal level adjustment
Inventor: KHALEGHI FARIDEH
IPC: H04B10/08
Filed: 1998-08-27
Granted: 2002-07-30
Abstract: The BER is used as a parameter for evaluating the performance of an optical transmission system. Performance of optical systems is also defined by the Q factor, which indicates the signal-to-noise ratio of the electric signal regenerated by the receiver. In the absence of distortion, Q is univocally determined by the BER. Q is calculated using an estimated BER measured with the path under normal conditions of operation, and a distortion-free Q is determined in the same operating point of the system. The distortion penalty for the path is obtained by comparing the measured Q with the distortion free Q. In addition, the distortion penalty for a transmittter-receiver pair, and a distortion penalty for a transmission link between the transmitter and receiver may be determined.

Abstract: Bioconjugués et administration d'agents bioactifs qui sont de préférence ciblés pour la libération spécifique à des sites au sein des cellules, tissus ou organes. Plus particulièrement, la présente invention concerne des bioconjugués qui comportent un agent bioactif et un complexe organocobalt. L'agent bioactif est lié de manière covalente directement ou indirectement à l'atome de cobalt du complexe organocobalt. L'agent bioactif est libéré du bioconjugué par le clivage de la liaison covalente entre l'agent bioactif et l'atome de cobalt du complexe organocobalt. Ledit clivage peut se produire en résultat d'un déplacement normal de nucléophiles cellulaires ou par action enzymatique, mais il est de préférence provoqué de manière à se produire de façon sélective à un site de libération prédéterminé par application d'un signal externe. Le signal externe peut être de la lumière ou la photoexcitation, par ex. la photolyse, ou peut être ultrasonique, par ex. la sonolyse. De plus, si la photolyse a lieu en présence d'un champ magnétique qui entoure le site de libération, la libération de l'agent bioactif dans les tissus sains environnants est maintenue à un minimum.

Abstract: The bimetallic plates (10) of the steam trap each comprise three same-direction active arms (17 to 19) extending transversely to the centre line (20) next to one another on either side of a centre line (20). On the centre line (20) there are provided two active arms (23) which extend in opposite directions to one another and transversely to the other active arms (17 to 19). On the side with concave deflection of the bimetallic plates (10) there are provided projections (27 to 30) as support faces for the active arms. The projections (27) of at least two active arms (17) project beyond those (28 to 30) of the other active arms (18, 19, 23). The projections (27 to 30) of the active arms (17 to 19, 23) come into effect at different temperatures and with accumulative force. The bimetallic plates (10) therefore have a closing force line well adapted to the saturated steam curve. (Fig. 2)

Title: Method and apparatus for electromagnetic exposure of planar or other materials
Inventor: JOINES WILLIAM T
IPC: H05B6/74
Filed: 1998-04-28
Granted: 2007-01-30
Abstract: The present invention overcomes many of the problems associated with electromagnetic exposure of planar materials (40). A diagonal slot (36) compensates for the effects of signal attenuation along the propagation path. Adjustably variable path lengths allow peaks (17) and valleys (18) of the electromagnetic field (16) in one exposure segment (30) to compensate for peaks and valleys in another exposure segment. Dielectric slabs may be used to extend the peak field region between top and bottom conducting surfaces (12, 14) to allow for more uniform exposure of planar materials (40) that have a significant thickness (41). Specialized choke flanges prevent the escape of electromagnetic energy. One or more~ rollers between exposure segments (30) may be enclosed by an outer surface to prevent the escape of electromagnetic energy.

Abstract: A wipe comprising a high internal phase inverse emulsion disposed in a discontinuous pattern on a substrate. The pattern provides areas coated with the emulsion and areas free of the emulsion. Preferably the emulsion is disposed so that the surface area to volume ratio of the emulsion is minimized. The emulsion locally expresses water during use upon the application of pressure to the wipe. The water is useful for cleaning. The discontinuous pattern of the emulsion provides regions of the substrate which are wetted during use and regions which may remain dry. The wetted regions transfer water to the surface to be cleaned. The dry regions then remove the water from the surface for more efficacious cleaning.

Title: Method and system for transient key digital time stamps
Inventor: DOYLE MICHAEL D
IPC: H04L9/32
Filed: 1998-09-22
Granted: 2009-01-27
Abstract: Irrefutable public key digital signature time-stamps (1040) are created and used based upon, for example, the concept of transient time-interval-related secret cryptographic keys (2010), which are used to digitally sign (2030) submitted data during specific time intervals, and then permanently destroyed (2040). The public-key correlate for each time interval is saved for future authentication of the content of time-stamped data and time of creation of time-stamped data. The validity of the public keys is ensured through the certification of each time interval's public key using the previous time interval's secret key, immediately before that secret key is destroyed.
