Patent CA-2204746-A1 (CA)
Inventor: STODDARD ROBERT B
IPC: A61B17/32
Filed: 1995-09-11
Abstract: A connection of first and second members (11 and 12) wherein each has a body and a connecting end with an inner surface (17) so the second connecting end (19) has an outer surface (20) shaped for telescoping into the inner surface (17) of the first connecting end (16). A shoulder (21) is located on the second member (12) and a groove (22) is in the outer surface (20) of the second connecting end (19). A raised nub (23) on the inner surface (17) of the first connecting end (16) is radially inward to engage the groove (22). An elastomeric gasket (13) is positioned to bear against the shoulder (21) and be compressed between the first and second bodies. An engaging trough (24) in the groove (22) holds the first connecting end (16) against the shoulder (21) with the nub against the groove (22) by the compression force of the gasket (13).  An indexing trough (25) in the groove (22) positioned along the groove (22) beyond the engaging trough (24) allows the nub to follow therethrough and slightly compress the gasket (13) thus giving the user a tactile indication that it has been rotated beyond the engaging trough (24). A method for fluid tight attachment of members (11 and 12) of a medical device has steps including the connection of the first and second members (11 and 12) with ends by telescoping the ends. Locating a groove (22) for operating the groove (22) as a cam (14) and locating a raised nub (23) of material on the inner surface (17) of the first connecting end (16) for positioning the raised nub (23) to engage the groove (22) for operating the raised nub (23) as a follower of the cam (14) are steps. Compressing a gasket (13) seal between the first connecting end (16) and the shoulder (21) while making the gasket (13) seal from an elastomeric material is a step. Positioning an engaging trough (24) in the groove (22) to hold the first and second connecting ends (19) against each other is a step. Positioning an indexing trough (25) in the groove (22) so when the nub is rotatably forced past the engaging trough (24) it will further compress the first end against the gasket (13) is a step.

Title: Fastening apparatus for and method of setting fastening elements
Inventor: GSCHWEND HANS
IPC: F16B19/00
Filed: 1997-05-09
Abstract: Fastening apparatus is formed of a drilling tool  for drilling an axially extending borehole in a receiving material.  The drilling tool  has a cutting member at its leading end and its trailing end  is arranged to be inserted into a chuck in a hand held drilling device capable of rotating the drilling tool and providing axially directed hammer-like blows.  A tubular fastening element has a bore extending between its leading and trailing ends and is arranged to be anchored in the borehole formed by the drilling tool.  The diameter of the bore in the fastening element is greater than the outside diameter of a cutting circle formed by the cutting member of the drilling tool. The drilling tool extends axially through the bore in the fastening element so that its cutting member projects from one end of the fastening element and its trailing end extends outwardly from the trailing end of the fastening element.  The drilling tool is rotated by the drilling device, however, the fastening element is not rotated.  While the borehole is being drilled by the drilling tool, the trailing end of the fastening element is contacted by the drilling device, directing hammer-like blow against the trailing end of the fastening element so that simultaneously the fastening element is driven into the borehole being formed by the drilling tool.  Due to its configuration, the fastening element is anchored in the borehole.  The fastening apparatus carries out a method of directly mounting the fastening element in a borehole, as the borehole is formed by the fastening apparatus.

Title: Automated, classified expenditure data card recording system
Inventor: YU MASON K
IPC: G06Q40/00
Filed: 1997-08-25
Abstract: This is an expenditure data recording system using a uniquely designed classification binary code (or its equivalent) stored within the point of sales terminal system consisting of a cash register, a credit/debit card reader, and a telecommunications line. In a sales transaction, a credit/debit card passes through this reconfigured point of sales terminal not only to furnish relevant information (date/time, vendor identification, cardholder's name and account number, and transaction amount), but also to classify the expenditure by category via instant telecommunications link upon approval by the credit/debit card issuer (financial institution). Whenever there is a needed classification change at the point of sales terminal, one utilizes a unique set of color, binary-encoded cards to redefine a new expenditure category. Whereupon the credit/debit card issuer can process this classified expenditure sales transaction information to produce a periodic financial report, and remit it to the credit/debit account holder at any time. This entire operational system is virtually transparent to the cardholder and sales personnel.
Patent CA-2212883-A1 (CA)
Inventor: COLIZZA VINCENT
IPC: G06F9/44
Filed: 1997-08-26
Abstract: A date value reduction system resolves the "Year 2000" problem in data processing. The input and output problems are resolved with the use of a "date translation object" (DTO) which translates an input date into a processing date (a reduced date value for processing purposes). This DTO similarly translates the processing date into an output date which is the actual date. The DTO may be embodied as a short sub-routine that can handle all possible date translation requests, whether adding the date value or subtracting it. A call to the DTO  is made at any time the processing software receives an input or outputs date related data. This call is inserted at the input and output command statements of the processing software. The command statements are readily located using a conventional hunting program. The insertion of the DTO is a simple process of locating the date references and scanning the processing instructions for input and output command statements used by the processing software language. This significantly minimizes the reprogramming of system programs and automatically ensures that the output data supplied to other systems or to users of the system needs no subsequent translation.

Title: Prioritized rule based method and apparatus for diagnosis and treatment of arrhythmias
Inventor: KAEMMERER WILLIAM F
IPC: A61N1/362
Filed: 1996-03-26
Abstract: An implantable antiarrhythmia device which detects and classifies arrhythmias of the human heart, and delivers appropriate therapy. The device employs a method of arrhythmia classification based on a set of prioritized rules, each of the rules defining a plurality of criteria based upon characteristics of sensed depolarizations of heart tissue, each rule being met when the criteria associated with the rule are met. Some rules, when met, trigger delivery of antiarrhythmia therapy. Other rules, when met, inhibit delivery of antiarrhythmia therapy. The rules may be met simultaneously, and if so, the highest priority rule governs the behavior of the device.
Patent CA-2216196-A1 (CA)
Inventor: KHADEM FEREIDOUN FEDOR
IPC: B65G39/00
Filed: 1997-11-14
Abstract: The idlers presently used on heavy-duty conveyors are subject to wear and therefore they have to be changed on a regular basis. The plant has to be shut down and the conveyor stopped to exchange the worn out idlers with the new ones. The exchange of the idlers takes place manually, which is time consuming and dangerous. This lengthy interruption of operations translates into expensive shutdown time. In major industrial and mining installations the number of idlers exchanged can be as high as 6,000 per year. To avoid long interruptions of the operation and in order to safely exchange the idlers, the "Idler Exchanger System" was invented, eliminating the manual handling of idler exchanges. The idler exchanger system is based on two separate operations, namely the lifting of the conveyor belt with the belt lifter and exchange of the idlers with the exchanger equipment. The belt lifter is clamped to the top of the conveyor frame and is equipped with two side rollers and one horizontal roller similar to the conveyor idlers. The belt lifter rollers are smaller in diameter than the conveyor idlers. The outside ends of the side rollers are moveable and can be raised by hydraulic rams and matched to the angle of the conveyor side idler. After the belt lifter is placed and clamped to the conveyor frame, the ends of the side rollers are raised and the angle is matched to the conveyor idler. Then the three rollers, the horizontal and the two side rollers, which are mounted on a secondary frame, called the roller system, are pushed upwards hydraulically and contact the conveyor belt. Pushing the roller system upwards, the three rollers of the belt lifter then lift the conveyor belt and gradually take over the load, and the worn out idler is accessible. After sufficient clearance is created between the idler and conveyor belt, the idler is then changed. The exchanger equipment is mounted on a separate frame, which will be placed on the other side of the exchangeable conveyor idler and is then clamped to the conveyor frame. The moveable arm of the exchanger equipment can be moved hydraulically to adjust its claws to the idler position. The claws are then closed hydraulically to hold the idler. The claws are moved upwards and the idler is then lifted from its place and removed. The new idler is picked up by the exchanger claws and the arm moves back to place the new idler to its position. The exchanger arm is then returned back and the exchanger equipment is removed from the conveyor frame. The roller system of the belt lifter is then returned slowly downwards and the conveyor idlers gradually take over the load. The hydraulic clamps are opened and the belt lifter equipment can be then removed from the conveyor frame as well.

Patent CA-2224994-A1 (CA)
Inventor: SODICKSON LESTER
IPC: G01N21/27
Filed: 1996-06-27
Abstract: The present invention provides apparatus and methods for determining the concentration of sample components of a sample by an analytical technique that yields a spectrum that can be written as Y(.omega.) = P(.omega.) . C. The apparatus and methods of the invention account for experimental errors that give rise to distortions in the observed spectrum and that consequently result in inaccurate determinations of sample component concentrations. The invention accounts for such errors by modeling the total experimental error as the sum of one or more types of errors that can be written as . K. The spectrum is then modeled as Y = P . C + . K. Using the observed spectrum, known values for P, and a mathematical model for , this equation can be solved for the best fit value of the sample component concentrations, C, and the magnitudes of the errors, K. The method can be used for any error that can be modeled in the foregoing manner, such as a shift in the spectrum. Particular types of shift include constant shift as well as linear shift across the entire spectrum. The apparatus and methods are advantageously used in absorbance spectroscopy and chromatography.
