Title: Variable Rate Pacemaker Having Upper Rate Limit Governor Based on Hemodynamic Performance
Inventor: WARREN JAY A
IPC: A61N1/365
Filed: 1992-01-07
Abstract: A rate adaptive pacemaker of the type having a variable rate cardiac stimulating pulse generator and a sensor for monitoring some physiologic parameter whereby the pulse generator stimulating rate can be adjusted to meet physiologic demand is further provided with a hemodynamic sensor which is operative to provide an output signal  representing  the  pumping  performance  of  the  heart  in response  to  the  pacing  stimulation.    The  signal  from  the hemodynamic sensor is processed and then used in an algorithm to determine whether further rate increase should be permitted based upon whether the rate increase would be accompanied by a further increase in cardiac output, a plateau or a decrease in cardiac output.   Hence, the adaptive rate pacemaker is provided with a real-time,  hemodynamic maximum pacing rate  instead of a pre-programmed, fixed, maximum rate.

Patent CA-2067527-A1 (CA)
Inventor: LADOUCEUR HAROLD A
IPC: F16B37/04
Filed: 1992-04-29
Abstract: A die member for joining a fastener to a panel includes a generally rectangular opening defined by two spaced apart opposed end walls, which receive the end walls of a pilot portion of a fastener. The end walls of the opening terminate into arcuate corners and are adapted to sheer and deform the pilot end walls of the fastener thereby forming bearing panel support abutments capable of providing a liquid tight seal between the panel and the fastener. The die member also includes clinching lips on opposed sides of the die opening. The clinching lips preferably include a top portion and tapered wall which deform the panel edges into grooved openings in the fastener thereby providing a liquid tight seal. The die opening is surrounded by a generally planar surface having an outer generally rectangular perimeter having generally arcuate corners. The generally arcuate corners form arcuate depressions within the panel when the die member operates on the fastener to attach it to the panel. The arcuate depressions resist stress fracturing of the panel when the panel and fastener assembly is subjected to high vibrational environments.

Title: Intake valve for internal combustion engine
Inventor: WALTERS CRAIG E
IPC: F02F1/42
Filed: 1991-08-14
Abstract: A valve (10) for an internal combustion engine (12 and 14) has a stem (28) and head (30) with differing diameters for the stems (28) and the upper portion of the head (30). A radially irregular blend region (32) placed between the stem (28) and upper head (38) is aligned to have a slight runout, that is, the axis of the blend region (32) is not coaxial with the axes of the stem (28) and the head (30). The blend region (32) is positioned on the valve (10) to be below the valve guide (20) when the valve (10) is closed and in the flowpath of the fuel mixture when the value (10) is open. The radially irregular blend region (32) creates additional turbulence which focuses the fuel mixture into the opening (40) between the open valve head (30) and cylinder head (14), thereby increasing the velocity of the fuel through the opening (20). In addition, a post (42) in the fuel passageway (18) deflects the fuel around the wider portion (36) of the valve head (30).

Filed: 1992-07-09
Abstract: SYNTHESIS GAS PRODUCTION         Synthesis gas production comprising primary catalytic steam reforming a first stream of desulphurised hydrocarbon feedstock, optionally followed by secondary reforming using an oxygen-containing gas, and then cooling; adiabatically low temperature steam reforming a second stream of the feedstock, preferably adding a hydrogen-containing gas, and then subjecting the product to partial oxidation with an oxygen-containing gas, and then cooling; and mixing the cooled products.          For methanol production, the partial oxidation step pressure may be greater than the primary reforming pressure, and the hydrogen-containing gas is taken from the methanol synthesis loop: if the partial oxidation step is non-catalytic and in the absence of steam, the pre-reforming stage can be omitted. Methanol can be synthesised from the reformed first and/or second streams in an auxiliary synthesis stage at an intermediate pressure before the relevant stream is added to the synthesis loop.

Title: A method of accessing a mobile radio land system from one of a number of mobile stations
Inventor: RAITH KRISTER
IPC: H04W56/00
Filed: 1992-07-31
Abstract: In a cellular mobile radiotelephone system, two different digital burst access methods are defined using to the greatest extent possible previously defined burst structures. The type of access method to be used in a particular cell is indicated on that cell's control channel. In very large cells, a two-burst access method is used including a shortened pre-access burst and a regular access burst. The shortened pre-access burst avoids collision with other bursts and provides time-alignment information to the cell's base station. In response to a time-alignment order, the mobile station then transmits a regular access burst. In smaller cells, a regular single-burst access procedure is used. The access methods use existing burst structures except that the fields CDVCC and SACCH are used for different purposes that may include improved synchronization, control channel identification and reservation of time slots for multi-burst access. Beyond a simple two-burst access method, according to a multi-burst access method, accesses may include essentially an arbitrary number of bursts limited only by system time-out limits.

Filed: 1992-08-10
Abstract: Two clamp members are formed to be fitted around the outer wall of a flexible sleeve when the ends of two pipes are located in the opening of the sleeve with adjacent edges of the two clamp members engaging each other in a clamped position for clamping the sleeve to the ends of the two pipes.  Each of the clamp members has two spaced apart clamping ridges extending radially inward from its inner wall continuously between its two edges.  The two clamping ridges of the two clamp members are located such that when the two clamp members are located around the outer wall of the sleeve and adjacent edges of the two clamp members engage each other, the two clamping ridges of the two clamp members form two spaced apart clamping ridges extending 360 degrees around the inside walls of the two clamp members for engaging the outside wall of the sleeve forming a seal between the sleeve and the ends of the two pipes when located in the opening of the sleeve.  One of the clamp members has arcuate extensions extending from its two edges located and having widths such that the extensions will fit between the two clamping ridges of the other of the clamp members when the two clamp members are located in the clamped position.  The clamp members are particularly useful with an industry approved gasket sleeve.

Patent CA-2079005-A1 (CA)
Inventor: BEGG GEOFFREY S
IPC: B01J19/00
Filed: 1991-04-11
Abstract: A first reactant is immobilized i.e. in a porous matrix (50), adjacent a sample electrode (46) within a reaction chamber.  Energizing of the electrode (46) electrophoretically attracts a mobile second reactant and/or electrolytically induces appropriate reaction conditions to enhance reaction of the first and second reactants. Polarity reversals between the sample electrode (46) and remote electrodes (38, 42, 44) cause unreacted second reactant and/or by-products to migrate away from the immobilized first reactant.  The techniques are useful for sequential chemical reactions such as sequencing or construction of proteins, polysaccharides and nucleic acids where cyclical additions and removals of reactants are required. The techniques are amenable to automated micro and nano scale construction and operation and allow direct electrophoretic (38) interfacing with chromatographic, HPCE and mass spectrophotometric equipment.
