Patent CA-2177353-C (CA)
Inventor: HARTMAN DAVID
IPC: B29C44/56
Filed: 1994-12-01
Granted: 1999-02-16
Abstract: A method for applying a closing tape to an extruded foam article is  disclosed.  The tape (40) is applied immediately after the article is extruded and while the article is still subject to shrinkage, which is common with extruded foamed products.  The tape is prestressed and is of a material to alleviate the problems associated with shrinkage. This method is particularly appropriate for applying  a  closing tape to an extruded polyethylene pipe insulation (2) product which has been longitudinally slit to allow the pipe to be located interior to the insulation.  The tape has one side attached to one side of the slit (9) with the other portion of the tape being positioned for closing the slit by engaging the opposite side of the slit.  A pressure sensitive adhesive is provied on the tape and a release liner protects the adhesive on the other portion of the tape.

Title: Zeolite-based lightweight concrete products
Inventor: FU YAN
IPC: C04B28/06
Filed: 1996-06-25
Granted: 2003-12-02
Abstract: Lightweight concrete products, useful for example in blocks, wall panels, floor and roof slabs, in which zeolite is a major component, its content in the cementing material of the products exceeding 50 wt.%.        Depending on application, zeolite may be non-treated or calcined at a temperature enabling the surface activation of the zeolite and resulting high surface energy.   Zeolite thus treated will work as both pozzolanic material and bubble-generating agent.    Strengthening agents are used to improve compressive strength of the products. Also, a binding material, useful for hazardous waste stabilization, comprising zeolite as a major component, is proposed.

Title: Photocleavable agents and conjugates for the detection and isolation of biomolecules
Inventor: ROTHSCHILD KENNETH J
IPC: G01N33/532
Filed: 1995-05-11
Granted: 2009-12-29
Abstract: This invention relates to agents and conjugates that can be used to detect and isolate target components from complex mixtures such as nucleic acids from biological samples, cells from bodily fluids, and nascent proteins from translation reactions. Agents comprise a detectable moiety bound to a photoreactive moiety. Conjugates comprise agents coupled to substrates by covalent bounds which can be selectively cleaved with the administration of electromagnetic  radiation. Targets substances labelled with detectable molecules can be easily identified and separated from a heterologous mixture of substances. Exposure of the conjugate to radiation releases the target in a functional form and completely unaltered. Using photocleavable molecular precursors as the conjugates, label can be incorporated into macromolecules, the nascent macromolecules isolated and the label completely removed. The invention also relates to targets isolated with these conjugates which may be useful as pharmaceutical agents or compositions that can be administered to humans and other mammals. Useful compositions include biological agents such as nucleic acids, proteins, lipids and cytokines. Conjugates can also be used to monitor the pathway and half-life of pharmaceutical compositions in vivo and in diagnostic, therapeutic and prophylactic purposes. The invention also relates to kits comprised of agents and conjugates that can be used for the detection of diseases, disorders and nearly any individual substance in a complex background of substances.

Abstract: An apparatus and method for programming a controller to vary the concentrati on set-point of an additive as a function of time. The present invention insures that the additive is injected to the machine at proper times to allow for optimum efficiency and lowest cost. To vary the set-point according to the input parameters, the invention combines the features of a data entry device, a microprocessor, a clock, a controller, and sensors into one unit. The user may enter a time setting a nd set-point into the controller, along with control parameters which allow the machine to control the additive injection based on different user-defined scenarios. The microprocessor then reads the settings and outputs an appropriate set-point value from the microprocessor to the controller. Thus, the user can manually or automatically change the response function if and when conditions change.

Abstract: A computerized two-dimensional illustration system composes an image of a scene with layered synthetic graphics filters or lenses. The scene is defined by an ordered list of shapes. Some of the shapes in the ordered list of shapes are lenses. Each lens is a shape that has a fill color which is an operator rather than a constant. The operator of a selected lens performs a filtering function on the shapes ordered below it in the list of shapes. To compose a selected lens inthe scene, the system computes an under-list of shapes for the selected lens. The under-list of shapes identifies shapes in the ordered list of shapes to which the filtering function of the selected lens may apply. After computing the under-list for a selected lens, the system freezes the shapes in the under-list and applies the filtering function of the selected lens to the shapes in the under-list. When a lens is frozen, it is replaced with a list of shapes that are formed independently of other shapes in the list of shapes. The scope of operation of the selected lens can be reduced by grouping the selected lens with other shapes in the scene as either a lens-in cluster or a lens-out cluster. A lens-incluster limits the scope of operation of the selected lens by operating on only those shapes in the cluster, while a lens-out cluster limits the scope of operation of the lens by operating on only those shapes outside the cluster. As a result of limiting the scope of operation, grouping lenses with other objects in a scene enables the creation of different visual effects. In addition, depending on whether a lens is grouped as a lens-in or a lens-out cluster, the computed under-list ofthe selected lens may have a reduced number of shapes, thereby reducing the computational complexity of composing an image of the scene.

Title: Atm service scheduler using reverse-binary scattering and time-space mapping
Inventor: BESHAI MAGED E
IPC: H04L12/56
Filed: 1998-12-02
Granted: 2005-04-19
Abstract: A method for scheduling low delay-jitter cell transmissions for multiple streams of Asynchronous Transfer Mode (ATM) traffic from a node is disclosed. Cells belonging to multiple streams of virtual circuits (VCs) and virtual paths (VPs) are stored in the node's memory. A link controller scans a time-space map to determine when a given stream will be sampled and its cells transmitted from the memory out over a link. The time-space map is comprised of time-slots whose spatial positions within the map correspond to times at which cells can be transmitted. A scattering technique, based on reverse-binary or other mapping schemes, ensures that each given stream occupies time-slots that are well-spaced within the time-space map. This ensures that cells belonging to a given stream are transmitted at well-spaced intervals of time.      The scheduler can provide each stream with a guaranteed real number of time-slots per time-space map, which allows for high resolution service rates to be supported without having to resort to using very large maps.

Abstract: The technique is based on comparing the spectral response of the "suspect" signal with that of a reference signal. The "suspect" signal is a signal detected in the weld heat-affected zone by a high-frequency (10 MHz), angle-beam (typically 45 degree) shear wave transducer operated in the pulse-echo mode. The reference signal is taken from the base metal next to the weld or heat-affected zone with two matched transducers of the same kind as the pulse-echo transducer but operated in the pitch-catch mode. The two signals are gated and Fast Fourier Transformed to the frequency domain for comparison. Relative to the reference spectrum, the high temperature hydrogen attack spectrum has an amplitude which increases with an increase of frequency, while welding defects and inclusions have the same frequency dependence as the reference spectrum. Therefore, localized high temperature hydrogen attack can be easily differentiated from other defects due to its unique spectral response.
