Title: Metallization of substrate(s) by a liquid/vapor deposition process
Inventor: NEWBERG SAMUEL S
IPC: C23C16/04
Filed: 2004-09-16
Abstract: A process for depositing a substantially pure, conformal metal layer on one or more substrates through the decomposition of a metal-containing precursor.  During this deposition process, the substrate(s) is maintained at a temperature greater than the decomposition temperature of the precursor while the surrounding atmosphere is maintained at a temperature lower than the decomposition temperature of the precursor. The precursor is dispersed within a transport medium, e.g., a vapor phase. The concentration of the metal-containing precursor(s) in the vapor phase, which also contains liquid therein, can be at a level to provide conditions at or near saturation for the metal precursor(s). In ensuring the aforementioned temperature control between the transport media and substrate, and in maintaining saturation conditions for the transport media, the quality of the deposited metal thin film is markedly improved and the production of by-product metal dust is greatly reduced or substantially eliminated.

Patent CA-2547218-A1 (CA)
Title: A high speed motion picture film processor
Inventor: MICHELSON MANFRED G
IPC: G03D3/13
Filed: 2006-05-17
Abstract: A high speed motion picture film processor has a developer tank having a positive pressure relative to an ambient air pressure outside of the tank. A  gas make-up system adds nitrogen inside of the developer tank while a system of seals minimizes leakage. Two seals are used along a periphery of the developer tank; one is below a sprocket level while the other is above the sprocket level. These two barriers can utilize a liquid reservoir that is filled by operation of the processor with excess liquid returning to the developer tank and they are constructed so as to allow movement. A film entrance sealing device and a film exit sealing device, each with its own housing, are also used with the developer tank; these units use a pair of rollers and a pair of flexible barriers to separate a tank gas chamber from an air chamber which is at a lower pressure and which contains a partial pressure of nitrogen fed into the entrance sealing device.  The level of developer fluid is maintained at approximately the centerline of a first roller shaft but below that of a second roller shaft. The sprocket shaft has two smaller shafts mounted in metal bearings and a center tube on which the sprockets are mounted. Oxygen sensors with throttling exhaust devices outside the developer tank sound an alarm when oxygen level is too high in the developer tank.      Reservoir fluid seals may also be used on secondary tanks.

Patent CA-2553380-A1 (CA)
Inventor: BEATON TIMOTHY P
IPC: E21B10/46
Filed: 2000-06-23
Abstract: A bi-center drill bit includes pilot and reaming blades affixed to a body at azimuthally spaced locations. The blades have PDC cutters attached at selected positions.  In one aspect, the pilot blades form a section having length along the bit axis less than about 80 percent of a diameter of the section. In another aspect, selected pilot blades and corresponding reaming blades are formed into single spiral structures. In another aspect, shapes and positions of the blades and inserts are selected so that lateral forces exerted by the reaming and the pilot sections are balanced as a single structure. Lateral forces are preferably balanced to within 10 percent of the total axial force on the bit. In another aspect, the center of mass of the bit is located less than about 2.5 percent of the diameter of the bit from the axis of rotation. In another aspect, jets are disposed in the reaming section oriented so that their axes are within about 30 degrees of normal to the axis of the bit. In another aspect, the reaming blades are shaped to conform to the radially least extensive, from the longitudinal axis, of a pass-through circle or a drill circle, so the cutters on the reaming blades drill at the drill diameter, without contact to the cutters on the reaming blades when the bit passes through an opening having about the pass-through diameter.

Abstract: A mechanism for the deployment of a filamentous endovascular device includes a flexible deployment tube having an open proximal end, and a coupling element attached to the proximal end of the endovascular device. The deployment tube includes a distal section terminating in an open distal end, with a lumen defined between the proximal and distal ends. A retention sleeve is fixed around the distal section and includes a distal extension extending a short distance past the distal end of the deployment tube. The endovascular device is attached to the distal end of the deployment tube by fixing the retention sleeve around the coupling element, so that the coupling element is releasably held within the distal extension of the deployment tube. In use, the deployment tube, with the implant attached to its distal end, is passed intravascularly through a microcatheter to a target vascular site until the endovascular device is located within the site. To detach the endovascular device from the deployment tube, a liquid is injected through the lumen of the deployment tube so as to apply pressure to the upstream side of the coupling element, which is thus pushed out of the retention sleeve by the fluid pressure. The coupling element may include an internal or peripheral purge passage that allows air to be purged from the microcatheter prior to the intravascular passage of the endovascular device.
