Patent CA-2103451-C (CA)
Inventor: BLANTON G KELLY
IPC: D06P1/54
Filed: 1992-05-20
Granted: 2002-07-23
Abstract: A flocked fabric has colors with long wearing capabilities and includes a textile substrate and raised disperse-dyeable fib-ers adhered to the substrate, an opaque particulate colorant adhering to the raised fibers and arrayed on the fabric in a printed pattern. A dye other than the opaque particulate colorant is also arrayed on the fabric in other portions of the printed pattern, such as in a blotch. A melamine-latex binder system causes the opaque particulate material to adhere to the fibers, and a resist causes the other dye not to dye the fibers in the area of the malamine-latex binder system. The opaque particulate colorant is ad-hered to the fibers strongly enough to show only very little wear after 15,000 cycles on a Wyzenbeek abrasion test.
Patent CA-2123752-C (CA)

Abstract: This invention relates to a photovoltaic system comprising a casing having mounted therein a plurality of solar cells. The casing has a front and opposite thereto, a rear. The front of the casing is provided with a light-transmitting panel for transmitting solar light to the solar cells. The rear is a double wall. A first wall is in contact with the back of the solar cells, and on its side away from the solar cells is of a dark-opaque colour, heat-absorbing surface.          The second wall is a light-transmitting enclosure of the dark-opaque colour side of the first wall, but spaced therefrom so as to produce a greenhouse effect. A method to remove snow, frost and ice over a photovoltaic system involves maintaining the light-transmitting panel at an angle with the horizontal, receiving reflected solar rays from the surroundings of the photovoltaic systems through the light-transmitting enclosure to the outer side being dark-opaque colour to be absorbed by the outer side and converted into heat to be transmitted to, and thereby to raise the temperature of the light-transmitting panel. Simultaneously the light-transmitting enclosure creates a greenhouse effect and thereby  an additional temperature increment to further raises the temperature of the light-transmitting panel to melt or sublimate snow, frost and ice present thereon.

Title: Method for reconstruction for mri signals
Inventor: SARTY GORDON E
IPC: G01R33/56
Filed: 1995-04-21
Granted: 2000-06-20
Abstract: A method and an apparatus are used in magnetic resonance imaging. In generating the resonance signals, the magnetic gradient fields are varied to represent a scan on a non-linear, continuously varying curve. One specific example given is a multi-leafed rose. New mathematical treatments of the resultant signal are presented, which are used to define a novel method for the reconstruction of an image from these signals based on k-plane coordinates naturally associated with the signal acquisition. The superior image quality that the new reconstruction method gives means that non-linear, continuously varying acquisition in k-space may be used so that magnetic field switching and high cost hardware is not required, while signal acquisition times are significantly reduced.

Abstract: This invention provides a cellular radiotelephone system which includes mobile stations which may be remotely programmed from a customer activation system to effect activation and other programming needs. Mobile stations are manufactured in a blank form that causes them to operate only in an inactive state. During activation, information describing the mobile station's electronic serial number (ESN) is collected along with area of use information. A mobile identification number (MIN) is assigned in response to the area of use information. A page message is directed to the mobile station operating in its inactive state, but the page message references the ESN of the mobile station.  While inactive, the mobile station detects pages directed to its ESN. A remote programming session is then performed wherein digital user-specific programming data, including the newly assigned MIN, are transferred to the mobile station over a voice channel using a control channel protocol. A novel cellular telephone which is configured for such remote activation, as well as the methods of remote activation are also provided.

Granted: 2000-11-07
Abstract: A method and system for supplying electrically conductive coating materials to an electrostatic dispenser with a parallel arrangement of subsystems selectably coupled to the dispenser by a four-port system voltage blocking valve, which electrically isolates the subsystems. The subsystems each include first and second piston cylinders that alternatingly receive a selected coating material from a corresponding manifold and supply the coating material to the dispenser by a subsystem voltageblocking valve, which isolates the dispenser from the manifold, when coupled to the dispenser. The first and second piston cylinders of each subsystem also alternatingly receive a solvent from the corresponding manifold and direct the solvent to a waste receptacle by a corresponding subsystem voltage blocking valve when the subsystem is not coupled to the dispenser. The solvent removes previously supplied coating material from the non-selected subsystem and readies the non-selected subsystem for supplying a next selected coating material to the dispenser.
