Patent CA-2426636-A1 (CA)
Title: Door holder
Inventor: WARTIAN GEORGE
IPC: E05F3/02
Filed: 2003-04-28
Abstract: A door holder has a piston reciprocable in a cylinder and a rod extending from the piston through one end of the cylinder. The outer end of the rod is pivoted to a door frame and the opposite end of the cylinder is pivoted to the door, or visa versa. A retainer is provided on the rod to prevent the piston and cylinder from contracting after the door has been opened. To release the retainer so that the piston and cylinder can contract, a coil spring is compressed between the retainer and the end of the cylinder. Upon a slight extension of the piston and cylinder beyond the door holding position, the spring pushes the retainer out of engagement with the cylinder so that the piston and cylinder can contract and the door can close.

Title: Adaptive selection of a warning limit in patient monitoring
Inventor: EGGERS PHILIP N
IPC: A61B5/00
Filed: 2002-04-22
Abstract: A patient is monitored by establishing a current warning limit for a physiological characteristic of the patient, providing a sensor for the physiological characteristic, and measuring a measured value of the physiological characteristic of the patient using the sensor. A revised warning limit is selected responsive to at least one of the steps of providing and measuring. The revised warning limit is then typically substituted for the current warning limit. The current warning limit serves to trigger some action in the event that the measured value of the physiological characteristic is not within an acceptable range defined by the current warning limit.

Inventor: CERENZIE ALBERT
IPC: B01D53/54
Filed: 2003-09-12
Abstract: The invention provides for an improved method of greatly reduce NOX, NITROGEN, emission from flue gas streams and create a CO2 rich exhaust stream. In particular, The separator is designed to recapture the CO2 rich exhaust stream. The concentration Of CO2, which is typically 5-10% in standard combustion processes, is increased to over 91 % with much of the remainder being water and low levels of NOX, and SOX.  Since The Emission gases are recapture all remainder larger solids (water), are separate out, fall to the bottom of the separator and are transferred to a holding tank for further treatment. The CO2 rich exhaust stream is (92% CO2, trace of NOX, SOX). The concentration of CO2 is so high, a standard mechanical refrigeration unit is all that is Required to further concentrate and capture industrial grade A CO2 liquid form. If the customer requires the CO2 in a gas form for Sequestration projects, then the process will required a booster that can boost the CO2, to a higher pressure into a pipe line for OIL      ENHANCED RECOVERY or COALBED METHANE RECOVERY or GREENHOUSES.

Inventor: PHUNG TRINH
IPC: A61M1/00
Filed: 1998-01-09
Abstract: Features is a device for draining fluids and/or gas from body cavities, including at least a pressure control chamber and a collection chamber being fluidly coupled by a one-way valve thereby establishing a waterless seal between the collection chamber, including the patient, and the suction source. The pressure control chamber also includes a waterless suction pressure control regulator that controls and maintains the suction pressure at or about a selected value. Preferably, the regulator includes a spring operated valve. The device also includes a vent path arrangement having an intermediate chamber and at least two passages that are perpendicular to two adjacent surfaces within the intermediate chamber. The two passages and intermediate chamber are arranged so liquid in the collection chamber does not flow and contaminate the upstream portions of the device when the device is resting on its front side or backside. Also featured is an autotransfusion system including a drainage device and a bag assembly attached thereto. The device and bag assembly are fluidly coupled so the differential pressure established by the device causes the blood from the patient to drain into the bag assembly. In an alternate embodiment, the drainage device is configured to continuously collect and filter a patient's blood and continuously output it for re-infusion back into the patient.
