Patent CA-2479389-A1 (CA)
Title: Pressure casting flow system
Inventor: MURRAY MORRIS TAYLOR
IPC: B22D17/20
Filed: 2003-02-14
Abstract: A metal flow system, for high pressure die casting of alloys using a machine having a pressurised source of molten alloy and a mould defining at least on e die cavity, defines a metal flow path by which alloy received from the pressurised source is able to flow into the die cavity. A first part of the length of the flow path includes a runner and a controlled expansion port (CEP) which increases in cross-sectional area, in the direction of alloy flo w, from an inlet end of the CEP at an outlet end of the runner to an outlet end of the CEP. A CEP exit module (CEM) forms a second part of the length of the flow path from the outlet end of the CEP. The increase in cross-sectional ar ea of the CEP is such that molten alloy, received at the CEP inlet end at a sufficient flow velocity, undergoes a reduction in flow velocity in its flow through the CEP whereby the alloy is caused to change from a molten state to a semi-solid state. The CEM has a form which controls the alloy flow whereby t he alloy flow velocity decreases progressively from the level at the outlet end of the CEP whereby, at the location at which the flow path communicates with the die cavity, the alloy flow velocity is at a level significantly below th e level at the outlet end of the CEP. The change in state generated in the CEP is able to be maintained substantially throughout filling of the die cavity and such that the alloy is able to undergo rapid solidification in the die cavity and back along the flow path towards the CEP.

Title: Method for improved safety in externally focused microwave thermotherapy for treating breast cancer
Inventor: MON JOHN
IPC: A61N5/02
Filed: 2003-07-15
Abstract: A method and apparatus that increases safety when employing externally focused adaptive phased array microwave thermotherapy (hyperthermia) for breast cancer treatment include microwave absorbing pads and metallic shielding to prevent undesired or stray surface tissue heating and to cushion the breast from mechanical pressure during breast compression. The microwave absorbing pads are attached on the top of the microwave waveguide thermotherapy applicators and on top of the breast compression paddles. A metallic-shielding strip mounted across the top portion of the microwave applicator aperture acts to block microwave radiation from illuminating the base of the breast and chest wall area. The patient treatment table utilizes a metallic shield to shield the body from stray microwave radiation. Combined E-field and temperature sensors within a single catheter are used to require only a single minimally invasive skin entry point for E-field focusing and measurement of the tumor temperature. Breast compression is maintained for a period of time following microwave-induced heating to accumulate additional equivalent thermal dose. Treatments incorporating the safety improvements include thermotherapy for early-stage breast carcinomas, locally advanced breast cancer, ductal carcinoma in-situ, and benign breast lesions.

Abstract: There is a need to embed images and lines in ice surfaces, such as the lines and team logos in hockey rinks and the circular targets in curling rinks. These images are often provided by painting the ice surface and flooding overtop, which is complex, expensive, time-consuming and labour-intensive, or by applying crepe paper to the ice surface, which is difficult to do without tearing the paper and in any event, lacks durability. Vinyl and plastic materials repel water and therefore do not adhere to the ice, tending to float away when flooding overtop is attempted. The system and method of the invention includes a matte-finish-coated polypropylene synthetic paper on which is printed the desired logos, images, geometric shapes, and/or lettering. This printed paper adheres to ice surface through the application of water, to be encased in the ice and visible above from the surface.

Title: Zipline braking and motion-arrest system
Inventor: STEELE CHARLES Z
IPC: B61H9/02
Filed: 2005-04-08
Abstract: Braking and motion-arrest apparatus for braking the arrival of a zipline cable rider at a landing platform and arresting the rider's motion to retain the rider at the platform. A frame is mounted on the cable to allow longitudinal rolling movement of the frame along the cable. A self-closing one-way latch is provided at the forward end of the frame. The latch includes a pair of capture plates which are normally inwardly biased toward one another, on opposite sides of the cable. The rider is tethered to a pulley block which rolls along the cable and collides with the latch. The collision force drives the plates laterally away from the cable, allowing the pulley block to roll through the latch. After the pulley block rolls past the latch, the plates' normal biasing closes the latch, preventing the pulley block from rolling back through the latch.
