Patent CA-2288580-A1 (CA)
Title: Pipe end burnishing tool
Inventor: CARTER SAM W
IPC: B24B23/02
Filed: 1999-11-05
Abstract: The burnishing tool has a shank that is mountable in a hand drill chuck. An end of the shank is received in a bore in an inside member with a conical inside burnishing surface. A transverse shaft passes through a slot through the inside member and a bore through the spindle to connect the inside member to the shank and to permit limited axial movement between the inside member and the shank. A cup member with an outside conical burnishing surface has a hub that receives a post on the inside member. The transverse shaft that connects the inside member to the shank also passes through a bore through the hub to secure the cup member to the shank. The connections between the shank, the inside member and the cup member permit movement of these members relative to each other to align the conical burnishing surfaces with pipe surfaces. The burnishing tool for two pipe diameters has a shank with a first conical burnishing surface on a shank. Second and third conical burnishing surfaces are on an inside cup member that receives the shank and is axially movable relative to the shank. A fourth conical burnishing surface is on an outside cup member that receives the shank and is substantially axially fixed relative to the shank.

IPC: G06F3/0484
Filed: 2000-01-28
Abstract: A color contrast adjuster is disclosed that automatically selects and applies a new color combination for text and background based on the current color combination for the text and background, if the current color combination is a problem color combination.  The text can be any text object (such as a hypertext link, bold text, underline text, groups of text, etc.) and the background can be any background object whose color can be determined (such as a solid color, a button, a global interchange format file, etc.). Additionally, the color contrast adjuster can store multiple problem and preferred color combinations for each user. The color contrast adjuster can replace a problem color combination with a preferred color combination.  Furthermore, the color contrast adjuster can provide example color combinations to a user, allow the user to select a better color combination, and add this preferred and problem combination to a user preferences. This allows the color contrast adjuster to adapt to additional problem color combinations. The color contrast adjuster can also provide the user with an indication of previous colors for objects whose color has been changed. This option is useful if the user is to select an object based on the color of the object.

Abstract: An improved breath coordinated inhaler (10) is provided for administering medication to a patient in aerosol form for respiratory inhalation therapy. The improved inhaler (10) comprises a compact housing (18) adapted to receive and support a medication canister (12), including a valve assembly (14) actuated to deliver a dosage of the medication in aerosol form. The housing (18) includes a plunger mounted at a first end thereof for displacing the canister against a spray nozzle (24) located at a second end of the housing to actuate the valve assembly (14), and deliver the medication through a mouthpiece (26) to the patient. The plunger (36) is associated with a seal arrangement for venting the housing (18) when the plunger is depressed to allow the patient to draw in air in timed relation to the medication delivery, and to substantially reseal the housing (18) against ingress of contaminants when the plunger (36) is released.

Abstract: A tire air valve (core) mounting and dismounting tool 20 includes a tool head portion 21, a shank portion 22 and a grip portion 23. The tool head portion 21 has a slot 32 for seizing and holding a valve core head portion 16, an axial bore 33 for accepting a valve core shaft portion 14 and its enlarged end 14a. The tool head portion 21 also has annular groove 34 formed along a cylindrical peripheral surface thereof. Balls 36 are retained in second bores 35 which are open to the annular groove 34 and also communicate with the axial bore 33 through openings 37 of a reduced diameter to allow the balls 36 to partially protrude into the axial bore 33. A coil spring 38 is anchored and fastened in the annular groove 34 to act to normally bias the ball 36 radially inwards and leave the balls 36 protruding into the axial bore 33. When the balls 36 are hit and pushed down by the valve core shaft's enlarged end 14a, the elasticity of the coil spring 38 allows the balls 36 to move radially outwards, permitting the valve core shaft end 14a to move deeper beyond the balls 36 and then permitting the balls 36 to restore their biased state, thereby holding the valve core shaft end 14a against moving back. Thus, the valve core is caught by the tool.

IPC: E06B3/62
Filed: 1998-09-16
Abstract: A method of forming a joint (32) between two plastics extrusions (10) is disclosed which comprises mitring the extrusions (10) so that they form the desired angle to one another, removing part of the rear face of each extrusion (10), placing the mitred extrusions in a mould and injecting a resin material whereby to bond the extrusions (10) to one another and produce the desired joint (32) configuration. Because the front surface (24) of the joint in accordance with the invention is entirely made up from the orginal extrusion, there are no problems with raised sight-lines, colour differentials, surface differences, or colour matching. Moreover, the method of the invention allows a corner to be produced which has a clean right angled rather than radiused inner portion.

Title: Method and apparatus for three-dimensional color scanning
Inventor: MIRAMONTI JOHN L
IPC: H04N13/221
Filed: 1997-10-24
Abstract: The invention provides a three-dimensional digital scanner which includes a multiple view detector which is responsive to a broad spectrum of visible light. The multiple view detector is operative to develop a plurality of images of a three-dimensional object which is being scanned. The plurality of images are taken from a plurality of relative angles with respect to the object, and the plurality of images depict a plurality of surface portions of the object. A digital processor including a computational unit is coupled to the detector and is responsive to the plurality of images so that it develops 3-D coordinate positions and related image information for the plurality of surface portions of the object. A three-dimensional image of the object to be scanned is thus developed by the digital processor. The data developed includes both shape and surface image color information.

Abstract: Devices and methods are described that permit simple correction of a fiber optic polarity reversal problem. An adapter is described having receptacles to receive a connector on a first end, or user end, and on a second end, or contractor end. Both the receptacles provide keying arrangements so that the connectors can be received only when correctly oriented with respect to the adapter. The keying arrangement on the contractor end, however, is reversable so that the connector may be inserted in one of two predetermined orientations, at the behest of the contractor or installer. Adapters are also described that receive connectors only in a physically reversed orientation to counteract a reverse polarity condition. In addition, a jumper is described that can be interposed between a connector and adapter to correct a reverse polarity condition.

Title: Architecture for increasing density of channel bank in digital carrier system
Inventor: CORP DAVID O
IPC: H04M3/00
Filed: 2000-08-09
Abstract: A double density channel bank architecture compatible with an existing D4 backplane and D4 channel units transmits or receive PCM data on the PAM bus, while simultaneously transmitting or receiving PCM data on the PCM bus. A double density channel unit (CU) provides data for two transmit and two receive T-1 timeslots to increase the capacity of a D4 channel bank from 48 channels to 96 channels.  Channel bank timing of PCM data on the PAM bus provides isolation of PCM data and PAM signals on PAM bus. Double density transmit and receive units each support an additional DS1. The receive unit transmits a signal on both CU channels to indicate T-1 failure and to commence trunk processing.
