Patent CA-2231514-A1 (CA)
Inventor: MYERS RONALD D
IPC: C08J11/16
Filed: 1996-10-25
Abstract: Un procédé de dévulcanisation et de fonctionnalisation d'un vulcanisat de caoutchouc par désulfuration consiste à mettre en suspension une poudre de vulcanisat de caoutchouc dans un solvent, lequel, de préférence, fait gonfler le vulcanisat de caoutchouc avant ou pendant la réaction de dévulcanisation, et à ajouter à la suspension un métal alcalin tel que du sodium. Le métal alcalin clive les réticulations mono-, di- et polysulfuriques dans le vulcanisat de caoutchouc afin de libérer un polymère de caoutchouc présentant un poids moléculaire sensiblement égal à celui du polymère de caoutchouc avant la vulcanisation. Des groupes fonctionnels dérivés des molécules de solvent se lient au squelette polymère du caoutchouc dévulcanisé. En plus du polymère de caoutchouc fonctionnalisé dévulcanisé, on peut également récupérer du noir de carbone destiné à être réutilisé selon le procédé de l'invention. On peut soumettre le caoutchouc fonctionnalisé dévulcanisé à une réaction de revulcanisation sans séparation du polymère de caoutchouc du solvent, par addition d'un mélange de durcissement approprié.

IPC: G16H20/30
Filed: 1996-09-27
Abstract: A system for providing the delivery of health care services to patients and in particular method and apparatus for monitoring the delivery of such services is disclosed. The system provides a method and apparatus by which an appropriate frequency of periodic treatment for patients is determined by scores or ratings assigned to selected criteria in a routine examination in which each of the criteria is weighted and in which each of the criteria is indicative of the health status of the patient. The ratings are combined with the weighting of its corresponding criterion, which are then accumulated to provide an overall score for the patient. The overall score is compared to a set of predetermined range of results which correspond to a particular health care servive to be provided, which is for example the recall frequency of a dental patient.
Patent CA-2234444-A1 (CA)
Inventor: SUNDERLAND MARK
IPC: A61M25/01
Filed: 1998-05-07
Abstract: Disclosed is a catheter driver for use with a flexible, elongated catheter having opposite ends and an intermediate portion and intended for manipulation by a user during insertion of the catheter into the body of a patient. The driver of the invention is constructed for one-handed operation making it easier for the user to guide the catheter into the patient while operating the driver and obviating the need for relinquishing control of the catheter for advancing the driver. The driver includes an elongated body for being gripped by a hand of the user, the body having a longitudinal axis and forward and rear ends; a longitudinally extending recess in the body for slidably receiving the intermediate portion of the catheter; and a lock structure operable by the same hand of the user for locking the intermediate portion of the catheter in the recess to allow application of axial thrust to the catheter.

Title: Automotive lift
Inventor: WALTERS RAY A
IPC: B66F7/08
Filed: 1998-04-19
Abstract: A parallelogram lift in which the deck rails are raised by lifting legs affixed to sliding members that slide within channels in the deck rails. Link arms pivotally connect to the deck rail to each leg, so that the deck rail lifts vertically. A single hydraulic actuator is used to actuate the legs supporting each deck rail, which ensures that the deck rail remains level during the lifting and lowering processes. In the preferred embodiment the hydraulic system is serially coupled between the hydraulic cylinders associated with each deck rail, which ensures that the displacement of hydraulic pistons raising both deck rails is synchronous so that the two deck rails are lifted at the same rate and remain horizontally aligned throughout lifting and lowering, and an incremental braking system is provided which automatically locks the deck rails into any desired elevated position, reducing the load on the hydraulic system and providing a failsafe against free-falling of the deck rails in the event of hydraulic failure.

Title: Dual-chamber type injector and connector used therefor
Inventor: WAKAMATSU KOTARO
IPC: A61J1/20
Filed: 1998-06-02
Abstract: A needle connecting portion of a syringe which includes a drug accommodating chamber accommodating a first component is  arranged opposite  to a takeout port  of a hermetically closed   container   which   includes   a   container   chamber accommodating a second component.  The syringe is connected to the container through a connector so as to be movable in proximity mutually  and  adapted  to  be  separable  from  the connector.  There is provided a communication passage capable of  communicating  the  drug  accommodating  chamber  with  the container chamber.  The communication passage is cut off by a closure member arranged between both of the chambers.   The syringe and the container chamber are moved in proximity to each other,  thereby displacing the closure member so as to open the communication passage.  An injector of the present invention  is  compact  in  shape  but  can  retain  sterility assuredly while being stored and mix both of the components accommodated therein surely through a simple operation just before  administration.     Further,   it  can  prevent  the piercingness of an injection needle from being damaged at the time of a mixing operation and easily remove a syringe after the mixing operation.

Title: Spoofing detection system for a satellite positioning system
Inventor: HARTMAN RANDOLPH G
IPC: G01S1/00
Filed: 1996-06-12
Abstract: A pair of antennae (230a, 230b) in combination with a GPS signal receiver system is employed for detecting the reception of satellite information signals from a spoofing signal transmitter as opposed to those satellite information signals transmitted aboard each of the satellite vehicles which form a satellite positioning system. An indication of the pointing angle (.alpha.) or (.beta.) between the line of the antennae and the actual transmitter transmitting the satellite information signals is detected. The pointing angle and/or alternatively the range difference derived from the outputs of respective receiver systems (240a, 240b) may be observed by monitoring the behavior of the pseudo random code associated with the carrier of the satellite information signal, or the carier itself. In turn, pseudo range measurements, pseudo range rate measurements, carrier phase measurements, and/or Doppler count measurement associated with the two antennae may be used to obtain the desired discriminant, which distinguishes between genuine satellite signals, and those re-radiated via the terrestrial antenna of the spoofing signal transmitter.

Abstract: In a multifocal ophthalmic lens comprising an aspherical surface having at every point thereon a mean sphere and a cylinder, a far vision region, a near vision region, and an intermediate vision region, the length of progression i.e. the length over which lens power varies by a set amount in different regions of the lens, is short. To avoid distortion at the periphery of the lens which this would otherwise occasion, the isosphere and isocylinder lines are distributed over the surface of the lens so as to ensure variations in sphere are not too sudden along a 20 mm radius circle centered on the geometric center of the lens and variations in cylinder on the surface of the lens inside this circle are also very small. The lens has an enlarged near vision region and progression is less perceptible to the wearer.

Title: Method for performing character recognition on a pixel matrix
Inventor: THOMPSON ARCHIE L
IPC: G06V10/44
Filed: 1997-09-05
Abstract: Character recognition is effected by categorizing a cipher by a unique description using three feature sets. In the process of the invention, lines are located by expanding or contracting the original image of the cipher to fit into a sparse space pixel matrix. The image is thinned to define lines (32) and so as not to obliterate lines which give the cipher its uniqueness.  Once the cipher is thinned, fuzzy logic is used to define a set of coordinates for each line in a cartesian coordinate system. After all the lines are located, the endpoints of each line are located and the intersection points are located (44). These three feature sets are encoded, resulting in three values, such as 64-bit integers (50). These three integers are used as search keys to query a relational database which contains the integer sets for known characters (53).
