Patent CA-2093685-C (CA)
Inventor: CASTONGUAY ROGER NEIL
IPC: H01H71/08
Filed: 1993-04-08
Granted: 2004-07-06
Abstract: A screw retainer is fabricated from a thin sheet of spring steel and is comprised of three sections: a screw support section, a leg support section and a leg section. The screw support section contains a through-hole for receiving a support screw. The leg support section is bounded by the screw-support section and the leg section. The leg section is angulated with respect to the leg support section and has a degree of spring action that allows it to be compressed so as to allow it and the leg support section to be inserted between the respective lower portions of integrally-formed upstanding support arms of a support base. Once the screw retainer is completely inserted between the respective lower portions of the integrally-formed upstanding support arms, the leg section springs back to its normal position thereby preventing the screw retainer from becoming dislodged from its position.

Title: Retrievable well packer
Inventor: HENDRICKSON JAMES DAVID
IPC: E21B33/128
Filed: 1993-05-12
Granted: 1998-06-16
Abstract: A retrievable packer for service at high temperatures and pressures has sealing provided by a seal element prop surface (56) of larger diameter than the seal element support surface (48) of a body mandrel (34).  At least one element (30A) of a seal assembly (30) is supported on the prop surface and is subjected to a radial squeeze in the set configuration, even though a lowermost seal element (30C) may be subject to longitudinal separation.  The split level support arrangement provides an annular pocket (62) into which the elements can be retracted upon release of the packer, thereby providing clearance for retrieval.  In releasing the packer, a retainer collar (68) is shifted away from a metal backup shoe (64), thereby providing an annular pocket into which the shoe is deflected, so that it does not obstruct the drift clearance during retrieval.  The seal element assembly is preloaded by a cover sleeve (50) which releases when a predetermined compression has been achieved.  The controlled preloading of the seal elements assists movement of the elements to the larger diameter prop surface, and the seal elements are forced to expand into the annulus uniformly to prevent the formation of uneven extrusion gaps.

Title: Thermistor airflow sensor assembly
Inventor: WILKINSON MARK A
IPC: G01F1/684
Filed: 1992-09-11
Granted: 1996-09-24
Abstract: A thermistor airflow sensor assembly adapted to be mounted adjacent the mouth and nose of a patient for monitoring  the  breathing  of  the  patient,  with  the assembly comprising thin, flexible, resilient layers of film adhesively secured to each other to form a laminate. Copper conductor strips are formed by etching away a copper  layer  attached  to  the  lower  film  prior  to lamination, with chip thermistors being soldered to the copper conducting strips. The thermistors are mounted in leg portions extending laterally from a main body strip of the assembly,  with two legs being adapted to be aligned with the nostrils of the patient, and the opposed leg extending downwardly to a position where the outer end thereof is generally aligned with the mouth of the patient.  The copper conducting strips extend through an enlarged end portion of the assembly for electrical connection to a cable, a bend relief cable, and a plug which can be connected to a monitor for providing visual and/or  audio alarm signals when breathing has been interrupted.  A separate carrier strip can be mounted on the film layer adapted to be positioned against the face of the patient, whereby the thin flexible assembly can be easily  adapted  to  the  facial  configuration  of  the patient.  The entire assembly, including adhesive and the copper conductor strips, is in the range of 0.006"-0.008" in thickness, except for the thermistor locations and the strain relief area.
Patent CA-2119507-C (CA)
Inventor: GUZINSKI MIROSLAW
IPC: H03M1/12
Filed: 1994-03-21
Granted: 1998-10-13
Abstract: A device, such as an A/D converter for generating successive codes, each in accordance with the level of an input analog voltage, may be tested to determine if all codes have been generated by applying a voltage V, having an amplitude that varies between 0 and V volts. The variation in the voltage V, is such that when the device is operating properly, it will generate all of its codes during a predetermined interval. Each code generated by the device is compared by a comparator to the count of an.pi.-bit counter whose count is initialized at zero. Each time the count of the counter matches the code produced by the device, the counter is incremented. If the counter overflows (i.e., its count has exceeded 2.pi.-1) within a prescribed interval, then the device is said to be operating properly.

Title: Optical reflection sensing arrangement for scanning devices
Inventor: KHVOSTOV VITOLD A
IPC: G07D7/12
Filed: 1996-02-20
Granted: 2007-07-03
Abstract: The optical scanner uses a unique compound optical system for processing reflected radiation in a manner to reduce the variations caused by changing position of a scanned substrate in a guideway. Two sources of radiation are directed at similar angles to the surface to be screened and the radiation is distributed over a larger area. Changes in position of the substrate in the guideway change the actual area reflecting the radiation sensed by the sensor, but the size of the reflecting area does not appreciably change. Any change effects both radiation systems in a similar manner.
Patent CA-2170800-C (CA)
Inventor: NEVIN MONIQUE A
IPC: A61H3/04

Granted: 1999-12-21
Abstract: The present invention is a hemi-wheeled walker which is particularly useful with respect to hemiplegics.      Patients of this type generally have one strong side of their body and one relatively weak side. Many patients have suffered from a stroke. The hemi-wheeled walker comprises an upright segment having a lower base portion extending parallel to the side of the user, with a handle at an upper portion thereof. The upright segment is a adapted for low force movement across a support surface when the user is supported on his strong side and adapted for gripping engagement with the support surface when the patient requires additional support when he is primarily supported by his weak side. A stabilizing segment is provided to one side of the upright segment and has at least one wheel at a point of contact of the stabilizing segment with the support surface. The stabilizing segment maintains the upright segment in an upright orientation and braces the upright segment against pivoting movement in a direction to the side of the user and towards the stabilizing segment. With this arrangement, the walker is designed to oppose or to minimize the patient falling to his strong side, which would be the tendency when the patient is supported on his weak leg and is moving his strong leg to the next position for walking. The low force movement of the walker across the support surface, when it is not used as a support aid, is highly desirable, as the patient is moving the walker generally with one hand and may otherwise have some difficulty in lifting and repositioning of the walker. It must be appreciated that many patients of this type are recovering and can be at various stages of recovery and often lack confidence. The support aid must be reliable and instill the confidence in the patient.
