Patent CA-2220949-A1 (CA)
Inventor: FRIEDMAN WILLIAM A
IPC: G01R33/28
Filed: 1995-05-24
Abstract: Repeat fixation for medical procedures is accomplished using a non-invasive locator, specifically a bite plate (26). The bite plate (26) has at least three fiducial markers (38) on it. The fiducial markers (38) may be LEDs, radiopaque markers for angiography or computerized tomography (CT) imaging or magnetic resonance markers for magnetic resonance (MR) imaging. By detecting the position of the markers (38), the position of features within the patient (14) (such as a brain tumor or other intracranial target to which radiation is to be applied) can be determined with great precision. Since the bite plate (26) has been molded to uniquely fit to the patient's teeth, it may be removed after an initial imaging of the patient (14). The bite plate (26) may then be re-attached one or more times to the teeth and the location of the features will be in a known position relative to the sensed markers.

Title: Method and apparatus for reducing tin defects in float glass
Inventor: FALLERONI CHARLENE A
IPC: C03B18/18
Filed: 1998-05-11
Abstract: The present invention provides a method of reducing tin defects in flat glass made by the float process. In the float process, molten glass is delivered onto a pool of molten tin within an enclosed chamber and formed into a glass ribbon. Oxygen gas dissolved in the molten tin combines with the tin to form tin oxide which vaporizes and collects within the chamber, resultingin defects in the glass. In the present invention, hydrogen gas is introduced directly into the molten tin to react with the oxygen gas and tin oxide within the molten tin to form water and elemental tin, resulting in a reduction in the amount of tin oxide within the molten tin. In one particular embodiment of the invention, the hydrogen gas is introduced into the molten tin through an elongated, porous graphite member submerged in the molten tin within the forming chamber such that it extends along and is located outboard of selected portions of the edge of the glass ribbon.

Title: Improved system for making absorbent paper products
Inventor: HERMAN JEFFREY B
IPC: D21F11/00
Filed: 1996-12-20
Abstract: An improved absorbent consumer paper product such as toilet tissue and a method and system for making such a product involves an improved drying fabric that forms an aesthetically pleasing and functionally superior pattern on the paper web before creping. The drying fabric is characterized by a plurality of shute threads extending substantially parallel to each other in a cross-direction of the drying fabric; and a plurality of warp threads extending substantially parallel to each other in a machine direction of the drying fabric. The shute and warp threads are woven together to define a number of relatively long warp knuckles. The long warp knuckles are positioned in a shed pattern. This pattern improves crepeability of the web and forms a bulky, absorbent, soft tissue product characterized by parallel, continuous low density ridges of substantially uncompressed fibers.
Patent CA-2240781-A1 (CA)
Title: Multi-stage check valve
Inventor: HARDING CURTIS F
IPC: F02C7/232
Filed: 1998-06-15
Abstract: A check valve includes an outer valve body and an inner poppet valve moveable relative to the valve body and spring-biased into a closed position. The inner poppet valve has first and second stage openings. The first stage preferably has a single, relatively small through-hole into the chamber of the poppet valve, while the second stage preferably has multiple openings of a larger diameter. The first and second stage openings are spaced axially along the poppet valve, with the first stage opening being located closer to the valve head of the poppet valve than the second stage openings. In the closed position, fluid flow is blocked through both the first and second stage openings. When the cracking force of the valve is exceeded and the valve head moves away from the valve seat, full flow occurs through the first stage opening and is restricted through the second stage openings. The restricted fluid flow causes the pressure drop across the check valve to be satisfactory at low flow rates to cause the poppet valve to stroke long enough such that particles will pass easily between the valve head and the valve seat. The flow increases through the second stage openings as the poppet valve moves toward its open position. The pressure drop is minimized at high flow rates to maximize theefficiency of the check valve. The check valve also has relatively few parts, and can be easily assembled and installed within the housing of a fuel nozzle.
Patent CA-2241363-A1 (CA)
Title: A method for accessing a microcell using analog control channels
Inventor: CHRISTIE EARL
IPC: H04W72/04
Filed: 1997-10-24
Abstract: The process of the present invention monitors a macrocell's control channel using a microcell having a control channel tuned to the same frequency and digital color code. Both the microcell and the macrocell have the same controller that waits for an access message. Once the access message is received, the controller waits for a duplicate access message within a predetermined time. If the duplicate access message is received from the microcell, the microcell's control channel RSSI of the radiotelephone is measured (RSSIm) to determine if it is greater than or equal to the threshold required for adequate communication with the microcell. If the RSSIm is greater than or equal to the threshold, the radiotelephone is assigned to the microcell. Otherwise, the radiotelephone is assigned to the macrocell.
