Patent CA-2246658-A1 (CA)
Inventor: FRENCH CLIVE JOHN
IPC: E21B43/116
Filed: 1997-02-21
Abstract: Apparatus for perforating a section of liner intersecting a hydrocarbonbearing formation comprises a length of tubing, the wall of the tubing defining a plurality of apertures, and perforating charges being located in the apertures. The tubing is adapted for mounting on the lower end of a length of production or test tubing such that the formation fluid may flow into the tubing and then directly into the production or test tubing. The charges disintegrate on detonation to leave the apertures unobstructed and to form light or small parts which may be swept out of the well by the formation fluid. Following detonation of the charges, the flow area of the tubing corresponds to the tubing internal diameter.

Title: Injection device with electronic presentation of set doses
Inventor: KLITMOSE LARS PETER
IPC: A61M/
Filed: 1997-03-03
Abstract: An injection device has signal generators (11, 12, 13, 14) which are connected to operative elements (8, 3, 5, 4) of the device and which give off signals which represents the operative condition of the device. The signals are sent to an electronic circuit which controls a presentation of the operational condition of the device and presents operational conditions, which are defined as not allowed, as error indications by switching off the display presenting the operational condition of the device. The number of signals from each generator is counted and a number of operations exceeding a pre-set number for the signal generator in question is interpreted as representing a not allowed operational condition.

Title: A system for ocular ultramicrosurgery
Inventor: CRINGLE STEPHEN JOHN
IPC: A61B34/00
Filed: 1997-04-17
Abstract: A system (10) for ocular ultramicrosurgery includes a ring (12) for immobilising eye (14) of a patient. The incision point (P) on the eye (14) for surgical tools is marked by a marker (16) that is generated by intersecting the beams of lasers (104 and 106). The intersection point of the laser beams is fixed in space. In order to move the patient's eye (14) so that point (P) coincides with that fixed point in space, the patient's head (52) is fixed to a head positioner (24). The head positioner is operated by a surgeon (26) through joystick (34) and computer (32) to ensure registration of point (P) and the point designated by the intersecting laser beams. All surgical tools used in the system (10) are supported, positioned and operated or worked by a tool support and positioning system (18). The system (18) comprises a stereotactic manipulator (20) and a tool translation table (22) which is supported on the manipulator (20). The manipulator (20) is used to position a surgical tool (50) on table (22) so that tip (51) of the tool (50) can be aligned with point (P). Thereafter, the manipulator (20) and/or table (22) can separately or in combination be used to pivot the tool (50) about point (P) so that the tip (51) of the tool is positioned at any desired location within the eye and subsequently worked or operated to perform ultramicrosurgery. Surgeon (26) is able to control the manipulator (20) and table (22) via computer (32) and input devices such as joysticks (34, 35) and keyboard (36). In this way, the surgeon's hands are isolated from the movement of the tool (50).

Title: Method and apparatus for surface finishing fabric with coated wires
Inventor: REDMAN CHARLES F
IPC: D06C13/08
Filed: 1999-01-20
Abstract: A method and apparatus for providing a soft finish on a fabric such as a suede tone, raised loops, broken loops or fleeced and for providing a faded effect such as a washed or faded denim. A fillet having a plurality of wires extending therefrom is wound on a cylinder of a finishing machine. The outer ends of the wires extending from the fillet are angled at approximately 80° from vertical. The wires are covered with an abrasive coating which is applied by an arc spray system. The coating extends around the perimeter of the wire from at least just below the bend of the wires and extending to the outer tip of the wires. The fabric is driven over a nip roll that is adjusted to bring the fabric in closer contact with the wires on the cylinder which is rotating.      An alternative embodiment of accomplishing the same type of soft finish such as suede or washed or faded denim finish is accomplished with multi rolls (or kiss rolls) finish machinery using the coated wire fillet on each roll. The wires of fillets for napping machines are similarly covered with the abrasive coating for achieving a more efficient operation on a napper finishing machine.

Title: Noded cuffs for transcutaneous or intrabody prosthetic devices
Inventor: SEARE WILLIAM J JR
IPC: A61M25/04
Filed: 1997-10-08
Abstract: This invention relates to methods and apparatus for making and using node cuffs (14) on transcutaneous or intra-body prosthetic devices (20) such as catheters, to effect improved stability of the prosthesis/tissue opening site interface. In particular, the node cuff apparatus of the present invention provides for positioning of the tissue opening site in a manner which facilitates more rapid establishment of a stably bio-integrated and well healed prosthesis/tissue opening site interface. In addition, in accord with the methods of the present invention, non bio-integrated portions of the node cuff can be simply and easily removed from the underlying prosthetic device to facilitate maintenance of the stably bio-integrated interface. Preferably, this removal takes place after a period of time during which the interface has become stably established. In accord with the methods and apparatus of the present invention, thus infections or healing difficulties at the prosthesis/tissue opening site interface are greatly reduced, and a more comfortable and stable interface is more rapidly established and more easily maintained.

Title: Method and apparatus for inspecting spark plug while spark plug is installed in engine
Inventor: SUZUKI NOBUAKI
IPC: H01T13/58
Filed: 1997-11-18
Abstract: Method and apparatus for inspecting a spark plug as installed in an engine, for an abnormal size of a discharge gap and cracking of porcelain, based on a shape parameter value Sn ( - Vn/Tn) calculated from a voltage parameter value Vn which is an average of primary voltage V 1 during a period of substantially inductive discharge, and a time parameter value Tn indicative of the period of the substantially inductive discharge. The inspection for the abnormal discharge gap size is effected with the engine held at rest, while the inspection for the porcelain cracking is effected with the engine controlled by a motor so as to increase air pressure within the cylinder bore, contrary to conventional system wherein the inspection is effected during operation of the engine by combustion of an air-fuel mixture.
