Patent CA-2102726-A1 (CA)
Inventor: HARRIS GERALD R
IPC: B23D55/04
Filed: 1993-11-09
Abstract: A method and apparatus for cutting at least one elongated workpiece (13b) with a saw head assembly (10b) having a cutting blade (11b). The saw assembly (10b) further includes a guide mechanism for providing relative guided movement between the cutting blade (11b) and the workpiece (13b) along a cutting line (14b). The method comprises the steps of placing the workpiece (13b) across the cutting line (14b).      Further, moving at least one of the cutting blade (11b) and the workpiece (13b) along the cutting line (14b) from a starting position (28b) on one side (27b') of said workpiece (13b) to a parked position (37b) on an opposite side (27b) of the workpiece (13b). In the parked position, the entire cutting stretch is positioned beyond the workpiece (13b). Next, the cut part or portion (32b) is displaced away from the cutting line (14b) using the workpiece (13b), while the cutting blade (11b) is in the parked position (37b).      Thereafter, the workpiece (13b) is returned to the opposite side of the cutting line (14b), and the cutting blade (11b) is returned from the parked position (37b) to the starting position (28b).      Accordingly, the cut parts (32b) and the workpiece (13b) are repositioned away from the cutting kerf (15b), which prevents their contact with the cutting blade (11b) during return of the cutting blade (11b) to the starting position (28b).

Abstract: FLUIDIZED BED REACTOR AND SYSTEM AND METHOD UTILIZING SAME                 Abstract of the Invention A fluidized bed reactor and system and method utilizing same for the combustion of waste fuels in which the reactor vessel is divided into three vessels.  Waste fuel is introduced into the fluidized bed within one vessel where it is mixed with bed make-up material that is controlled to provide an ideal environment for the generation of pyrolytic gases.  The fluidized bed material is pneumatically and gravitationally conveyed downwardly, and injected into a fluidized bed within the second vessel where the involatile organic material undergoes combustion in an oxidizing atmosphere.  The bed material in the second vessel is pneumatically conveyed upwardly and divided into two portions, one of which is recycled back to the first vessel.  The other portion of the bed material in the second vessel is circulated to a fluidized bed within the third vessel where heat is recovered.  The bed material in the heat recovery vessel is gravitationally conveyed back to the second vessel to regulate the temperature in the latter vessel.

Inventor: CLARK JAY V
IPC: G09B7/02
Filed: 1993-09-30
Abstract: A method and system for increasing the speed at which test answers are processed. The system receives electronic representations of test answers and organizes the test answers into separate groupings. The system next displays a particular grouping of test answers to a test resolver so that the resolver can score the test answers. In displaying the answers, the system uses a matrix of cells and displays one test answer in each of the cells. The test resolver can thus simultaneously view multiple test answers, which facilitates efficient scoring of the answers.

Title: Apparatus and method for generating an anti-aliased display image halo
Inventor: JOHNSON MICHAEL J
IPC: G09G5/36
Filed: 1992-08-21
Abstract: Apparatus and method are disclosed for providing a halo (background region) around selected image data in an anti-aliased image processing system. The anti-aliased image processing system applies a distribution function (601) to an image (impulse) point so that the impulse point contributes to the display (101, 500) for a plurality of pixels. In order to provide a halo. a second or halo distribution function (602), extending beyond the anti-aliasing distribution function (601), is assigned to selected impulse points. For the current pixel, the pixel for which the display attributes are being determined, the contribution to the current pixel from neighboring pixels for both the anti-aliasing distribution function (601) and the halo distribution function (602) are determined separately. Then the contributions from each source are combined to determine the display characteristics of the currently activated pixel. The invention provides a technique for combining or prioritizing contributions from display regions including overlapping sets impulse points.

Title: Contact touchscreen with an improved insulated spacer arrangement
IPC: G06F3/045
Filed: 1992-11-17
Abstract: A contact sensor comprises a first sheet of flexible material and second sheet. The first sheet is capable of being energized to establish an electrical potential thereon. The second sheet can be energized to establish an electrical potential in juxtaposition with the first sheet. The two sheets are formed of materials that tend to stick together. To keep the sheets apart, a plurality of substantially uniform discrete insulating islands are used. By the use of a non-square insulating island spacing pattern with the island spacing satisfying rigorous criteria, the two sheets can be prevented from sticking together without unduly increasing the amount of force required to activate the device. The sensor is particularly useful as a transparent touchscreen.

Title: Transcoding device with information signal transmission
Inventor: KOPPELMANS JOHANNES F A
IPC: H04N7/50
Filed: 1994-07-26
Abstract: Known transcoders for compressed video signals comprise a decoder and a coder coupled thereto, between which a data signal is transmitted. Because compressed video signals comprise so-called difference pictures and normal pictures, both the decoder and the coder should have a feedback loop which is utilized in decoding and coding a difference picture and is not utilized in decoding and coding a normal picture. For example, for the purpose of prediction means (motion compensation and motion estimation) present in the feedback loop of the coder, much computation has to be carried out in the coder. The computation required is considerably reduced by con-comitantly transmitting one or more information signals in addition to the data signal in a transcoder according to the invention, and complete decoding and complete coding no longer takes place.

Abstract: An internetworking node for providing internetworking services for mobile wireless nodes is disclosed. Each mobile wireless node is associated with at the most one internetworking node. Each mobile wireless node selects which internetworking node it will associate with. The internetworking node will then act for all wireless nodes associated to it in relaying messages between wireless nodes or between a wired lan and the wireless nodes. A tracking mechanism for such a system which maintains a table of all the internetworking nodes the wireless node has recently heard and deleting all such internetworking nodes which have not been heard recently is disclosed. A switching mechanism for such a system for determining when the wireless mobile node should switch its association from one internetworking node to another is also disclosed. The switching mechanism determines whether a particular internetworking node overheard by the mobile wireless node has been heard recently, and if not will associate with such an internetworking node. Otherwise the wireless node maintains its current association, with a particular internetworking node until a failure to communicate occurs or the said tracking mechanism deletes its reference to the said internetworking node.
