Patent CA-2146022-A1 (CA)
Inventor: SHAN XUEKANG
IPC: H01S3/067
Filed: 1994-02-23
Abstract: A method is described of stabilising the output of a mode-locked fibre ring laser (1). The fibre constituting the laser (1) includes a dopant in its core. The method comprises the steps of ajusting the length of the ring laser (1) to minimise variations in its cavity length, and hence lock the phase of the laser output pulses with that of its drive source (2), and subjecting a portion (1a) of the fibre of the ring laser (1) to vibrations at a predetermined frequency whose period is less than the dopant ion upper state lifetime.

Patent CA-2151555-A1 (CA)
Title: Sternal closure device
Inventor: PASQUE MICHAEL K
IPC: A61B17/82
Filed: 1995-06-12
Abstract: A surgical device and method are disclosed for closing the sternum following a median sternotomy. Instead of using stainless steel wire or a flat steel band, a strand of flexible suture material is used which is compressible in its radial dimension, but which resists compression and seeks to return to its full diameter in an elastic manner when radially compressed. Despite its radial compressibility, the strand must also be strong and relatively inelastic in its longitudinal dimension. This combination of traits can be provided by a hollow tubular shape, a foam-type or other compressible outer layer surrounding an inelastic core, or other suitable design. When not compressed, the sternal closure strand has a diameter slightly larger than the diameter of the needle used to emplace the strand in position around the sternal halves, between the ribs. After insertion, the expandable suture material will provide gentle pressure against the surrounding tissue, to minimize bleeding in the needle track. The soft suture material will also help cushion, distribute, and minimize the stresses and damage inflicted on the sternum or ribs during postoperative ambulation; this can provide major benefits, especially among elderly and infirmpatients who require open-chest surgery. An optional fastener device which provides additional advantages is also disclosed.
Patent CA-2154246-A1 (CA)
Title: Production of particle-stabilized metal foams
Inventor: THOMAS MARTIN
IPC: C22C1/08
Filed: 1994-01-21
Abstract: The invention relates to a process for producing a particle-stabilized metal foam from a composite capable of acting as a precursor composite for the metal foam. The precursor composite is formed by heating a matrix metal, e.g. aluminum or an aluminum alloy, above its liquidus temperature to form a liquid matrix metal, adding to the liquid matrix metal stabilizer particles capable of remaining dispersed within the matrix metal, e.g. MgO particles preferably in the form of agglomerates of particles and some fine particles, and mixing the liquid matrix metal and stabilizer particles under a covering gas, e.g. air, in such a way that bubbles of the gas, as well as the stabilizing particles, ace dispersed throughout the matrix metal. The precursor composite can then be foamed by the introduction of a gas by a known technique to form a particle-stabilized metal foam. The entrainment of gas bubbles means that a microporosity may be introduced into see of the cell walls of the composite, which is retained when the composite is transformed into a metal foam.     The foam product has improved crush and machining properties.

Patent CA-2163257-A1 (CA)
Inventor: HAYES DONALD J
IPC: B41J2/16
Filed: 1994-05-13
Abstract: A high density ink jet printhead is fabricated by first  forming a  body  subassembly  comprising  a piezoelectric  main  block  having  metallic  layers disposed on opposite first and second sides thereof, and piezoelectric sheets secured to front portions of the metallic layers.  Using a precision dicing saw, a first spaced series of parallel grooves, longitudinally extending between the front and rear ends of the subassembly,  are  cut  into  the  first  side  of  the subassembly.  The subassembly is then placed, groove side down, in a support fixture having mirrors secured thereto and positioned adjacent the opposite ends of the grooves.  Reflections of opposite groove ends in the mirrors are then used as line-of-sight guides to position the saw which is then used to form a second series of grooves in the second subassembly side which are in precise lateral alignment with the first series of grooves.  Covering blocks are then secured to the opposite piezoelectric sheets over the open outer sides of  the  grooves  and  form  therewith  interior  ink receiving channels bounded along their  lengths by piezoelectrically deflectable side wall segments of the printhead body.   The rear ends of the channels are sealed off, ink supply conduits are communicated with rear end portions of the channels, and a plate member having first and second spaced series of ink discharge orifices respectively communicated with the front ends of the first and second series of interior channels is secured over the front end of the printhead body.

Patent CA-2195299-A1 (CA)
Title: Tire studded pipe pig
Inventor: WATTS ROBERT
IPC: B08B9/055
Filed: 1995-06-19
Abstract: Pipe pigs are used to clean buildup from within pipes. They are forced through the pipe with a motivating fluid. This invention contemplates a novel shape of pig better able to accommodate bends or even sharp turns within a pipe. A snow tire stud is used on the exterior of a rubber, preferably urethane pig which has a diameter generally that is equal to the pipe size. In one aspect of the invention the pig is ovoid shaped. In a design for sharp turns a spherical pig is used. Finally, an improved method of using the pig is specified. The method contemplates monitoring motivating fluid pressure as a function of pig travel within the pipe. After a pressure drop, pig travel direction is reversed, thereby concentrating cleaning effort on those few areas with reduced internal diameter which most need cleaning.

Abstract: Sur les billets de loterie instantanée à zone de grattage, on sait qu'on utilise une encre grattable qui recouvre une information (un lot, gagnant ou non). La présente invention est un procédé qui empêche qu'on reconstitue la zone de grattage originale (par décalque, transfert ou autrement) et revende (ou autrement ré-utilise) le ticket. Ce procédé consiste à appliquer sur la zone de grattage telle qu'elle existe actuellement, une zone d'impression sécuritaire faite d'une couche d'encre ou de vemis qui déborde la zone de grattage. L'ioriginalité d'une grille de sécurité (sous forme de dessin ou autre graphisme) dans cette couche, confirmable à la lecture à l'ultra-violet (u.v.), et l'epaisseur de cette couche en rendent la reconstitution impossible.
