Patent CA-2057274-C (CA)
Title: Article comprising a metal body with a layer of superconductor material thereon, and method of making the article
Inventor: JIN SUNGHO
IPC: H01B13/00
Filed: 1991-12-09
Granted: 1996-04-02
Abstract: A method of making a ribbon-like or sheet-like superconducting composite body is disclosed.  The method is well suited for making long lengths (e.g., >100m) of ribbon or large areas (e.g., >100cm2) of sheet-like composite.  The method comprises forming a Bi-Sr-Ca-Cu-oxide-containing layer on a metal (exemplarily Ag) substrate, and mechanically deforming (typically by rolling) the thus formed composite such that the oxide is densified to more than 80% of the theoretical density.  Subsequently the oxide layer is at least partially melted and allowed to re-solidify such that a large portion of the oxide crystals has c-axis alignment.  After appropriate heat treatment in an O2-containing atmosphere, thus produced superconductor ribbons or sheets can have high Jc ( 104, frequently > 105 A/cm2) for temperatures less than about 20K and in magnetic fields less than about 5T.

Title: Adjustable drilling mechanism
Inventor: LEE PAUL
IPC: E21B17/07
Filed: 1992-01-23
Granted: 2001-10-30
Abstract: A down hole drilling tool activating mechanism is provided which will adjustably activate tool elements such as stabilizer pads by means of a mandrel which will move vertically against a bias spring and has inclined surfaces to bear on the inside of the adjustable pads creating variable diameters. The mandrel has a series of flexible fingers which engage the main body of the tool. A male spline element is provided which moves vertically within the body of the tool so that a portion thereof moves between a position in which it engages the fingers and forces them into engagement thereby locking the mandrel against vertical movement and a second unlocked position in which the portion is removed from the fingers allowing them to flex and allowing them to disengage the body so that the mandrel may move vertically changing the adjustment of the tool. An improved version may be provided with means to equalize pump pressure between the inner bore and outer surface of the male spline element to prevent unwanted relative movement due to increased pump pressure.

Title: Polyolefin coupler for joining polyolefin pipe
Inventor: STAFFORD TREVOR GEORGE
IPC: B29C65/14
Filed: 1992-04-23
Granted: 1997-05-06
Abstract: A coupler 10 consists of a length of cross-linked polyethylene pipe having a spiral groove 16 cut in its outer surface and another spiral groove cut in its inner surface.  A heating element 18 is wound in the groove.  The coupler is expanded mechanically so as to have an easy fit over the ends of polyethylene pipes 12, 14.  The heater element 18 is energised and the coupler shrinks and forms fusion welded joints between itself and the pipes.  No preparation of the pipe ends is necessary because the serrated inner surface cuts through the oxidised skin and bonds to material beneath the skin.  The coupler is especially advantageous in large sizes of 500 mm or above.  Instead of an electric heater, radiant energy, eg infra red or light is used to heat the coupler.  For example, an array of reflector lamps can be used circumferentially located around the coupler.

Filed: 1992-08-04
Granted: 2000-10-24
Abstract: A microphone mask to be worn in front of the mouth of an underwater diver has a microphone assembly and a teethpiece assembly mounted in a rubber waterproof enclosure. The enclosure has an air passage extending from an inlet opening to a rear outlet opening. The teethpiece assembly includes a plastic insert with a vertical plate mounted in the enclosure. The vertical plate has openings for the air passage as well as to allow sound to travel from the diver's mouth to the microphone assembly. A teeth member extends rearwardly out of the outlet opening into the diver's mouth where it is held between the diver's teeth. The teeth member is connected to the insert by resilient spring members which draw the enclosure rearwardly against the diver's face. There is a sealing surface around the outlet opening, and this seals it around the outside of the diver's mouth. This eliminates the need for a headband and facilitates the use of the microphone mask for the combination of breathing and speaking.

Title: Descrete phase shift mask writing
Inventor: MURAY ANDREW J
IPC: G03F1/28
Filed: 1992-09-10
Granted: 2001-02-13
Abstract: A method and apparatus for photolithographically fabricating features on a very large scale integrated circuit wafer by use of a phase shift mask defining discrete regions. This overcomes the problems of intensity nulls at the junction of regions formed by portions of the mask having opposite phase. The mask includes a transition region defining three phases which are assigned to pixels in the transition region, such that the phase assignment of the pixels is synthesized from an algorithm taking into account optical resolution and depth of focus. Each pixel is assigned one of three discrete phases, which thereby creates a transition region simulating a ramp between the two regions of opposite phases, such that intensity variation of the optical image corresponding to the transition region is minimized.

Title: Implantable cardioverter defibrillator having a smaller displacement volume
Inventor: KROLL MARK W
IPC: H01M16/00
Filed: 1993-04-07
Granted: 2001-07-24
Abstract: A capacitor-discharge implantable cardioverter defibrillator (ICD) has a relatively smaller displacement volume of less than about 90cc. The smaller volume of the ICD is achieved by selecting and arranging the internal components of the ICD to deliver a maximum defibrillation countershock optimized in terms of a minimum physiologically effective current (I pe), rather than a minimum defibrillation threshold energy (DFT). As a result of the optimization in terms of a minimum effective cur-rent I pe, there is a significant decrease in the maximum electrical charge energy (E c) that must be stored by the capacitor of the ICD to less than about 30 Joules, even though a higher safety margin is provided for by the device. Due to this decrease in the maximum E c, as well as corollary decreases in the effective capacitance value required for the capacitor and the net energy storage required of the battery, the overall displacement volume of the ICD is reduced to the point where subcutane-ous implantation of the device in the pectoral region of human patients is practical. The size of the capacitor is reduced be-cause the effective capacitance required can be less than about 125 µF. By optimizing both the charging time and the counter-shock duration for the smaller maximum E c, the size of the battery is reduced because the total energy storage capacity can be less than about 1.0 Amp-hours. In the preferred embodiment, the charging time for each defibrillation countershock is re-duced to less than about 10 seconds and the pulse duration of the countershock is reduced to less than about 6 milliseconds.

Filed: 1994-10-21
Granted: 1998-06-09
Abstract: A  sector  servo,  zone  bit  recording  disk  drive includes a sector architecture in which the recording head locates and identifies data sectors without using data ID fields,  but instead  using  information obtained from electronic storage and from servo sectors which need not be adjacent to the datasectors.  The tracks contain servo information and data, but not data sector ID information.   The  tracks  in  each  zone  are  circumferentially divided into segments.  Included in each segment is a number of data regions separated from one another by servo sectors.  The data regions may contain partial data sectorsand complete data sectors.   The  format  information  provided  to identify andlocate data sectors, including ones whose region locations are not adjacent to servo sectors, includes an entry for each region in the section.  Each entry includes the lengths of the first and last data sections in the region, whether the sectors represented by those sections are split between two regions, the total number of data sectors in the region, and the sector number of the first data sector in the region.   The information provided in the servo sectors consists of a servo sector number or other indicia which enables the disk drive to determine the position of the recording head and begin reading or writing immediately upon settling on-track and without incurring a latency penalty.
