Patent CA-2042658-A1 (CA)
Inventor: PETTUS RONALD G
IPC: E21B34/02
Filed: 1991-05-15
Abstract: Abstract of the Disclosure A  fail-close  hydraulically  actuated  control  choke includes  a  choke  with  inlet  and  outlet  flow  passages intersecting in a cylindrical flow chamber.  A reverse acting trim configuration which utilizes downstream pressure to assist in closing includes a flow cage with a wear sleeve of tungsten carbide shrink fitted therein is reciprocable within the flow chamber to control flow between the inlet and outlet flow passages.  The flow cage is closed at one end with a stem extending therefrom which is reciprocated by a fail-close hydraulic actuator.  The hydraulic actuator includes a pressure responsive piston in combination with a torque operated  driving  mechanism.    The  driving mechanism  is positioned within the piston and includes a traveling nut assembly to allow manual positioning of the stem and flow cage independently of the position of the piston.   The pressure responsive piston is double acting with a boost pressure supplied to the closing side of the piston and a signal pressure supplied to the opening side of the piston. A loss of signal pressure causes the boost pressure to shift the piston, stem and cage to a closed position.  Restoration of the signal pressure moves the cage to its original flow controlling position without requiring a resetting of the flow cage position.   Additionally,  should the hydraulic circuits or pressure responsive piston become inoperable, the torque operated driving mechanism can still reposition the cage as needed.

Title: Quarter lid
Inventor: POISSON ROLLAND M J
IPC: B65D43/02
Filed: 1992-04-06
Abstract: "ABSTRACT"     The Quarter Lid This invention is designed specifically for use with round containers such as  paint cans which contents  are  applied to specific  surfaces using a paint brush as the applicator.   The quater lid fits into existing groves on the container, and provides a straight flat edge that allows the user of the brush by pressing the wide flat sides of the brush to remove excess liquid from the brush,  more efficiently that with a rounded edge.   By reducing  or  eliminating liquid from collecting in re-sealing groves on the container it is  assumed that a savings will be realized from a more proper re-sealing of 1iquid in the container.  The more efficient removal of excess liquid from the brush will help to eliminate the messy dripping and excess build-up of liquid on the brush and so provide easier clean-up of brush.

Title: Analyzing heart wall motion using spatial modulation of magnetization
Inventor: AXEL LEON
IPC: G01R33/48
Filed: 1991-08-19
Abstract: A technique for generating "optimal" radio frequency pulses for use in creating SPAMM imaging stripes and for quantitatively de-termining the displacements of the imaging stripes during a pre-imag-ing interval. The imaging operator selects the desired stripe parame-ters (304) so that the resulting SPAMM imaging stripe will have the desired narrowness, sharpness, flatness and the like. These parame-ters are then used by an optimal pulse generating system (212) to gen-erate the input radio frequency pulse sequence which will produce the desired stripes. Tagging of the heart wall or some other soft tissue structure with a grid of planes of altered magnetization is then used to provide finite element analysis to quantify regional heart wall motion and the like. The intersections of the tagging stripes are used as a set of fiducial marks within the heart wall, and the motion of these inter-sections through the heart cycle is used to track the motion of the un-derlying tissue.
