Patent CA-2131900-A1 (CA)
Title: Liquid dispenser
Inventor: LEVINE MARSHALL S
IPC: A61B19/00
Filed: 1993-03-12
Abstract: A dispenser (20) for blood and other biological speci-mens (11) is disclosed which provides a means of obtaining a small predetermined quantity of specimen from a closed con-tainer (10) without the need to remove the stopper (13) from the container. The cannula (19) of the device is caused to pierce the container's rubber stopper forming an assembly.      When the said assembly is forced against a target surface; such as microscope slide (30), the force compresses the stop-per and thereby reduces the volume inside the container suffi-ciently to eject a drop of fluid which is dispensed onto a target surface. Stabilizing supports (26) are provided so that fluid emerges from a dispensing tip (22) located a predetermined distance above the target surface which determines the quanti-ty of fluid dispensed. The supports also transmit reactive force from the target surface to compress the rubber stopper of the closed specimen tube.

Patent CA-2159336-A1 (CA)
Inventor: AXE JOHN R
IPC: A62B7/00
Filed: 1994-04-14
Abstract: A method and device for controlling sleep disorder breathing utilizes variable multiple level pressures. A pressure source (43) supplies compressed breathable gas at a relatively low pressure to the user's airway. Pressure transducers (45, 48) monitor pressures and convert them into electrical signals. The electrical signals are filtered and processed (49, 55) to extract specific features such as duration and energy levels. If these features exceed selected threshold values for duration and energy level over a minimum period of time, then the microprocessor (57) declares the presence of sleep disorder breathing. If a selected number of these events occur within a selected time period, then the microprocessor adjusts the pressure delivered by the pressure source. If sleep disorder breathing is not detected within a certain time period, then the microprocessor lowers the pressure level gradually.    The device and method disclosed in this patent is capable of detecting apnea, hypopnea, and pharyngeal wall vibration. Further, it is able to distinguish between obstructive, central and mixed apnea and hypopnea.
Patent CA-2160443-A1 (CA)
Title: Booster compressor system
Inventor: KEDDIE DAVID
IPC: F04C11/00
Filed: 1995-10-12
Abstract: A  booster  compressor  system  modulates  discharge pressure with a proportional regulator in fluid communication between the compressor discharge and a servo control for a valve to the compressor inlet.  The servo control comprises a double acting piston connected to  a valve control  rod.   In  one embodiment, the proportional regulator is of a negative signal type and communicates to a side of the piston for urging the piston to a valve opening position.  A valve dosing pressure is applied by a non-relieving regulator in fluid communication between the compressor discharge and the other side of the servo control piston.   As the discharge pressure  increases,  the proportional  regulator outlet  pressure  decreases  thereby resulting in the servo control allowing the intake valve to the compressor  inlet  to  close.    This,  in  turn,  reduces  the compressor  discharge  pressure  thereby  resulting  in  the proportional regulator controlling the valve to partially open once more.  In a second embodiment, the proportional regulator is of a positive signal type and communicates to a side of the piston for urging the piston to a valve closing position.   A valve closing pressure is applied by a non-relieving regulator in fluid communication between the compressor discharge and the other side of the servo control piston.

Filed: 1995-12-05
Abstract: A flask for standard solutions comprises a flask body and a closure cap for sealingly closing the flask body.  It has in an upper part of the flask body a capillary passage communicating with a chamber for containing the solution.  The flask is filled and/or emptied through the capillary passage.  The capillary passage acts as a recondensation zone and reduces evaporative escape of solvents upon removal of the liquid, even when the closure cap is closed.  The risk of contamination of the solution in the flask is also reduced. The narrow opening of the capillary passage can be sealingly closed with the closure cap of the flask.  After the closure cap is removed the solution can be easily completely removed through the capillary passage using a syringe, without having to tilt the flask.
