Patent CA-2119949-A1 (CA)
Title: Steel beam cutter
Inventor: TOZER GARY
IPC: B23K15/00
Filed: 1994-03-25
Abstract: On a bridge construction site, or on other submerged foundation work, the H-beam piles are cut at a specific height above the ground.  The piles are normally cut by divers using an electrical arc gouging process.      This invention provides a means for cutting these beams with plasma arc electrodes, which are remotely controlled  from  a  floating  barge,  or  from  similar structure above the water level.      The cutting torches are mounted on a trolley.  The trolley is lowered with a winch along the H-beam pile, to the desired depth.  Then, each torch is energized and activated to cut both flanges and the web of the beam at the same plane.      The new machine provides a method for cutting steel piles  which  is  safer  and  more  efficient  than  the conventional diving operation.

Patent CA-2133133-A1 (CA)
Title: Two-piece header
Inventor: BERTVA JOHN T
IPC: F28F9/02
Filed: 1994-09-28
Abstract: A parallel  flow  condenser  having  a  plurality  of substantially flat,  parallel  flow tubes are positioned between  oppositely  disposed  headers.    The  flow  tubes provide fluid communication between the headers for cooling fluid which flows through the condenser.   Each of the headers is formed from an inner member having an inner wall and a pair of longitudinally extending, parallel sidewalls which protrude outward from the inner wall.  The parallel sidewalls terminate in outer edges.   An outer member is provided having an outer wall and a pair of longitudinally extending attachment flanges which project inward from the outer wall.  The attachment flanges are positioned between the  parallel  sidewalls  of  the  inner  member with  the attachment  flanges overlapping and  joining one of the parallel sidewalls so that the inner and outer members are effectively joined together to form a fluid passage.  The inner edges are spaced apart from each other a distance less than the width of each of the flow tubes so that the ends of the flow tubes contact the inner edges of the attachment flanges, which act as stops, to prevent the tubes from being inserted too far into the openings of the inner wall of the header.

Inventor: DURMAN BERNARD J
IPC: A61M39/06
Filed: 1994-11-10
Abstract: A self sealing flexible elastomeric valve is disclosed. The valve can be used to seal a trocar device from loss of gas pressure during a laparoscopic surgical procedure when a surgical instrument is inserted therethrough as well as when no instrument is inserted. The preferred one piece valve includes a flange having an aperture, and a cylindrical wall section which extends to a pair of mutually opposed sealing wall sections defining a generally S-shaped slit. This slit configuration at the end of these wall sections define the sealing surfaces. The flange preferably includes a concentrically dome shaped region with the aperture centrally displayed. The valve also is preferably composed of a silicone rubber.      The valve has the advantages of simplicity of manufacture and assembly and the ability to provide an adequate seal against the surface of any surgical instrument inserted through it. Also, the improved valve will require a small amount of force to insert instruments and will resist eversion of the valve walls when instruments are withdrawn.      A trocar assembly incorporating the sealing valve as described above is also disclosed.

Patent CA-2150490-A1 (CA)
Title: Backplane bus for differential signals
Inventor: MORANO DAVID A
IPC: H03K19/018
Filed: 1995-05-30
Abstract: A differential voltage bus system is disclosed wherein the two leads of the bus are biased by the termination networks with a predetermined voltage difference representing a digital signal of one binary type.  The bus driver in each bus master connects a current source to one of the two bus leads and a current sink to the other of the two bus leads in response to an input digital signal of the other binary type thereby changing the voltage difference on the bus to represent the other binary type.   In response to an input digital signal of the first-mentioned binary type, the bus driver isolates the current source and sink from the bus and connects them together in order to decrease the detrimental effect of transients. The selective switching in the bus driver is performed by MOSFET switches which are driven by buffer driver circuits each of which uses a combination of MOSFETs and an NPN transistor to drive its respective MOSFET switch with a high peak current thereby enabling rapid switching.  The current source and sink in the bus driver also uses a combination of MOSFETs and NPN transistors in order to permit operation of the bus a low voltage levels.
