Patent CA-2055405-A1 (CA)
Inventor: MAYZES EDWARD W
IPC: G01V1/137
Filed: 1991-11-13
Abstract: A monoport airgun for seismic exploration has a single discharge  port  extending  continuously  for  360°  around  its longitudinal axis.  This airgun has a first housing providing a firing chamber containing pressurized gaseous fluid (gas) and a second housing providing an operating chamber.  The first and second  housings  are  positioned  in  alignment  along  the longitudinal axis.  They are spaced apart along this axis for defining the discharge port between them extending continuously around the axis.  The two housings of the monoport airgun are interconnected solely by a guide member concentric with the axis.          A shuttle encircling the guide member is movable therealong between closed and open positions.   In closed position,  the shuttle closes the firing chamber for retaining pressurized gas therein.  In open position, the shuttle opens the firing chamber to the discharge port for allowing pressurized gas to blast from the firing chamber through the discharge port.  The discharge port which extends continuously around the axis flares outwardly in generally exponential horn-like configuration for enhancing effectiveness of the discharge port in generating seismic energy waves.  A passageway in the guide member supplies pressurized gas from the operating chamber to the firing chamber when the shuttle is in closed position.  This passageway is blocked by the shuttle in open position.

Title: Stent delivery system
Inventor: HARTIGAN WILLIAM M
IPC: A61F2/06
Filed: 1992-01-27
Abstract: ABSTRACT OF THE DISCLOSURE   The invention is directed to a stent delivery method and system which generally includes an elongated delivery sheath and a catheter disposed within an inner lumen of the sheath having an expandable member on its distal extremity. An expandable stent is mounted on the expandable member of the catheter. A manipulating device is provided on the proximal end of the delivery system to effect relative axial movement between the sheath and the catheter so as to expose the stent mounted on the expandable member on the catheter within a body lumen such as a coronary artery and allow the expansion of the stent by the expansion of the expandable member. The delivery sheath has a first port in its distal end and a second port in the sheath wall proximally disposed from the distal end of the sheath. The catheter likewise has a first port in its distal end and a second port proximally disposed from the distal end of the catheter. An inner lumen extends within the distal portion of the catheter between the first and second ports and slidably receives a guiding member such as a guidewire. This system allows the stent to be delivered over a guidewire previously advanced to the desired location within a body lumen.

Patent CA-2064961-A1 (CA)
Inventor: YOSHII YUJI
IPC: F04C29/04
Filed: 1992-04-02
Abstract: The present invention is directed to a scroll type compressor having an injection mechanism in which a part of the refrigerant flowing from the condenser is combined with the refrigerant in the intermediately located fluid pockets of the scroll elements in order to increase the amount of heat radiation from the refrigerant in the condenser without increasing the capacity of the compressor and in order to prevent operation of the compressor at a thermally severe condition. The injection mechanism includes a horseshoe-shaped groove formed between a circular end plate of a fixed scroll and an end portion of a casing adjacent to the circular end plate, a pair of axial conduits formed through the end plate of the fixed scroll and an axial hole formed through the end portion of the casing. The refrigerant is conducted to the intermediately located fluid pockets of the scroll elements via the axial hole, the groove and the axial conduits which are connected in series for fluid communication. In accordance with the present invention, the injection mechanism is easily assembled, and the thermal influence of the high temperature discharged refrigerant gas in the discharge chamber of the injection mechanism is negligible so that the operation of the compressor at a thermally severe condition is effectively prevented.

Patent CA-2070711-A1 (CA)
Inventor: CULP GORDON W
IPC: H01L41/09
Filed: 1992-06-08
Abstract: ABSTRACT OF THE DISCLOSURE   This  invention  is  for an object moving  actuator composed  of  a stack of independently controllable layers which convert thermal exobaric pulses into mechanical motion. Each layer can be a lifter for moving the stack normal to the object to be moved or a tangenter for moving the stack tangentially to the object. Each layer has a plurality of chambers having a heat source and a thermal expansive material contained therein. The heat source  is  controlled  by a  controller to  generate  a  heat pulse which expands the thermal expansive material thereby moving a rolling barrier to make the  layer move  normally  or tangentially.  Preferably  two  pair of actuator stacks work together to alternately engage and move the object.          The first pair makes contact with the object by lifter motion and moves the object by tangenter motion while the second pair is lifted off the object and  retraces  to get  into position to contact and translate the object. When the actuator engages the object at the same speed the object is moving so that no frictional rubbing occurs, smooth walking motion is acheived.

The increasing pattern is divided into two steps consisting of a first step and a subsequent second step.  The first step has a pattern in which the heating temperature is increased under a reduced pressure atmosphere and a gas comprising at least an inert gas is supplied to the vacuum furnace under the reduced pressure atmosphere.  The second step has a pattern in which the heating temperature is increased under a reduced pressure atmosphere in which a gas comprising a smaller amount of an inert gas than in the first step is supplied to the furnace or under a vacuum pressure atmosphere in which no gas is supplied to the furnace.
