Title: Absorbent foams made from high internal phase emulsions useful for acquiring aqueous fluids
Inventor: DESMARAIS THOMAS ALLEN
IPC: C08F212/08
Filed: 1996-01-11
Abstract: Absorbent foam materials that are capable of acquiring and distributing aqueous fluids, especially discharged body fluids such as urine. These absorbent foams combine relatively high capillary absorption pressures and capacity-per-weight properties that allow them to acquire fluid, with or without the aid of gravity. These absorbent foams also give up this fluid efficiently to higher absorption pressure storage materials, including foam-based absorbent fluid storage components, without collapsing. These absorbent foams are made by polymerizing high internal phase emulsions (HIPEs).

Patent CA-2212476-A1 (CA)
Title: Remote-dosing analyte concentration meter
Inventor: PUGH JERRY THOMAS
IPC: G01N21/27
Filed: 1997-08-07
Abstract: A meter is used in conjunction with a hollow, frustum-shaped disposable device to measure the concentration of an analyte in a sample of a biological fluid.  The smaller end of the frustum has a porous membrane, to which a sample of the fluid may be applied.  Preferably, a reagent in the membrane reacts with the analyte to cause a color change.  The meter has a frustum-shapeddistal section that mates with the device.  The meter measures the color change and computes from the change the analyte concentration in the sample. The meter and disposable device permit remote dosing of the device, which minimizes the likelihood of cross-contamination between the user and the meter.  Devices can be mounted on the meter and released from the meter without touching them, to further protect against contamination.

IPC: A61M25/09
Filed: 1996-02-28
Abstract: Implements, particularly medical instruments, formed at least in part of elongated polymer members, exhibit high torque fidelity after processing with tension, heat, and twisting. The processing orients the polymer in generally helical paths so that torque imposed at the proximal end can be transmitted to the distal end without substantial whipping, even if the implement follows a long and tortuous pathway. Applications include a medical guide wire (2) with stiff portion (14), transition portion (16) and flexible portion (18), a catheter (140) and driveshaft.

Patent CA-2223228-A1 (CA)
Inventor: ZAKIM DAVID S
IPC: G01N21/35
Filed: 1996-06-06
Abstract: A machine-based method for collecting and interpreting quantitative data on cells and tissues so that a diagnosis will obtain as to the existence or non-existence of disease in a human. Vibrational spectroscopy is used and the spectra generated by such spectroscopy are compared with stored spectra to provide whether cells or tissues are diseased, and if diseased to what degree.  It, therefore, is possible to provide a basis for immediate diagnostic decisions for patients and physicians, leading in turn to immediate implementation of next-step procedures and treatment all in one visit to the doctor's office. This means that patients and the examining clinician can know almost instantly whether or not the cells or tissue examined are normal or diseased, and the level of disease present if found. The advantages of bringing the diagnostic pathology service directly into the doctor's office include immediate relief to the patient's concern about health as well as immediate clarification of what needs to be done next in order to treat the disease that is present, and include any other actions that are necessary. The need for biopsies to obtain desired information on the existence or non-existence of disease is obviated. That is, there is a rapid identification of the area of tissue that is affected by disease prior to obtaining biopsies.  This makes it possible to apply a single standard of diagnostic accuracy anywhere in the world, independent of the local availability of pathologists or other professionals.

Patent CA-2233372-A1 (CA)
Inventor: KOOPMAN CHARLES HENRY
IPC: E05F1/14
Filed: 1998-03-26
Abstract: A door hinge and closure mechanism which includes a hinge unit and a closure unit is described. The hinge and closure units are integral in that a hinge plate of the hinge unit serves as a support for components of the closure unit. Generally, the closure unit applies a pre-load force on the door when the door is in a closed position. When the door is between a closed position and a neutral force position, the closure unit applies a substantially constant closure force on the door. Once the door is opened beyond a first lock position, the closure unit applies resisting forces to the door when the door which act as a deterrent to further opening of the door. Rather than being expanded during door opening as with known spring closure mechanisms,the spring of the above described closure unit is compressed. Compressing the spring is believed to result in a more smooth and constant closure force on the door, as well as extending the useful life of the spring. Further, a single screw mounts hinge and closure mechanism to the door, which facilitates easy assembly and removal of the door from the cabinet. Also, no component of the mechanism is mounted internallywithin the door. Rather, all the components are mounted externally of the door, which facilitates avoiding energy loss due to the location of metal parts within the door. The mechanism also provides sufficient closure force so that designed-in rear tilt of the cabinet is unnecessary to ensure proper closure of the door.
