Patent CA-2287547-A1 (CA)
Inventor: WILEY THOMAS WILLIAM
IPC: E01C23/14
Filed: 1999-10-27
Abstract: A method and apparatus for heating an asphalt-paved road surface by forcing gases heated by a heater against that road surface and then returning those gases to the heater for reheating and recirculation, wherein the temperature of the returning gases is measured by a temperature sensor, and the heater is automatically adjusted so that the temperature of the gases being directed against the road surface is automatically decreased as the temperature of the returning gases increases. This prevents damage to the asphalt and premature rupturing of the road surface.

Title: Magnetic stirrer adapted for use with microwave ovens
Inventor: GOMES FRANCIS
IPC: H05B6/80
Filed: 2000-02-01
Abstract: A stirring device is adaptable for use in microwave ovens with turntables. The stirring device includes a gear train assembly that increases the normal rate of revolution of a microwave turntable by several fold. A driving head coupler is connected to a driving end of the gear train assembly and engages a turntable driving head, so that rotation of the driving head during use of the microwave oven causes rotation of the driving head coupler. A magnetic stirring actuator is connected to a driven end of the gear train assembly for rotation therewith. A magnetic stirring device is positioned in a container along with the contents to be heated and stirred. During use of the microwave oven, the turntable driving head rotates at a first rate of revolution and thereby causes a corresponding rotation of the actuator at a second rate of revolution greater than the first rate to thereby simultaneously heat and stir the contents situated in the container at the second rate of revolution. The driving head coupler is adaptable for use with microwave ovens having different sizes of driving heads.

Title: Method of cutting a workpiece along an arcuate path with a plasma arc torch
Inventor: TURNER BARRY GASKINS
IPC: B23K10/00
Filed: 2000-03-29
Abstract: A method of cutting a workpiece along a cutting path that is arcuate or that has one or more arcuate portions includes the step of determining a control parameter that is proportional to the angular velocity of the torch. The arc current supplied to the torch is regulated based on the control parameter and the linear advance rate of the torch, which in turn is a function of the material type and thickness of the workpiece. In one embodiment of the invention suitable for the cutting of holes, the control parameter is the diameter of the hole to be cut, which for a specified linear advance rate is inversely proportional to the angular velocity of the torch. The current is increased above a nominal current when the hole diameter is less than or equal to a predetermined limiting diameter, and otherwise is set at the nominal current. In other embodiments of the invention suitable for cutting holes or other shapes, the control parameter is the radius of curvature of the cutting path. Alternatively, the angular velocity can be used as the control parameter. Increasing the current at higher angular velocities and/or when cutting holes of small diameter tends to reduce the problem of the arc not following the desired cutting path and creating cut surfaces that do not conform to the desired cut surfaces.

Inventor: HUGHES RICHARD P
IPC: G02B6/42
Filed: 2000-12-11
Abstract: To mount two semiconductor optical devices together such that a coupling face of one is aligned with and close to the coupling face of the other the devices are mounted on two different carriers. A first one of the carriers is flat and has a vertical edge and carries the optical device such that its coupling face is flush with the vertical edge. A second one of the carriers may be flat or wedge-shaped and has a vertical edge and carries the other optical device such that its coupling face is flush with that vertical edge. A flat baseplate supports the flat carrier. The second carrier is supported on an inclined plane which may be formed on a separate wedge supported on the baseplate or which may be formed as an inclined surface portion on the baseplate. By sliding the flat carrier on the baseplate relative to the second carrier and sliding the second carrier up or down the inclined plane the coupling faces may be aligned.      The application of liquid adhesive facilitates the sliding action and permits easy securing after alignment by curing the adhesive.
