Patent CA-2353791-A1 (CA)
Inventor: MAHLAB URI
IPC: H04Q11/00
Filed: 2001-07-25
Abstract: An optical switching apparatus in an optical communication network selectively combines and separates series of optical signal samples using OTDM and/or WDM. In upstream communication, the optical switching apparatus optically converts n series of upstream optical signal samples having the upstream optical signal samples carried over channel wavelengths .lambda.1,...,.lambda.n at data rates DR1,...,DR n respectively into a combined series of upstream optical signal samples having the upstream optical signal samples carried over a channel wavelength .lambda.D at a combined data rate DR c which is greater than any one of the data rates DR1,...,DR n.  The combined series of upstream optical signal samples is then routed to a destination route. In downstream communication, the optical switching apparatus optically converts a series of downstream optical signal samples carried over a channel wavelength .lambda.T at a data rate DR T into nn series of downstream optical signal samples having the downstream optical signal samples carried over channel wavelengths .lambda.1,...,.lambda.nn-1, .lambda.T at data rates DRT1,...,DRT nn. The nn series of downstream optical signal samples are then routed to nn routes respectively. Related apparatus and methods are also described.

Abstract: The present invention is directed generally to client-server, client-host, o r server-server communications in a distributed computer network and, more particularly, to enhancing of resource adapters adapted to facilitate such communications. The present invention is directed to enhancing resource adapters that work with screens. Aspects of the invention , which may be incorporated into or communicate with existing resource adapters, provide a standard screen record for manipulating data on a screen image. The standard screen record provides support for instances where prior knowledge of the screen format or layout is known and for those instances where there is no knowledge of the screen format. Additionally, the standard  screen record provides detailed data describing all attributes of a field and of the scree n image itself. Additionally, the invention also provides easy access to the field attribute  data. In some embodiments, aspects of the invention may include interfaces which enable tooling to be developed which can then be used to develop applications which utilize the functionality of the other aspects of the invention. This interface could provide a common way fo r tooling to support resource adapters that implemented the interface.

Title: Inclined emulsion treater
Inventor: KOMISTEK STEPHEN M
IPC: C09K23/04
Filed: 2000-02-07
Abstract: An emulsion treater has an elongate vessel for receiving oil in which water is emulsified and gas is entrained, and for separating these impurities from the oil. The vessel is supported so that the axis is oblique through the horizontal, thus defining an upper and a lower end, each of which is closed by a head which may be hemispherical in shape. An elongate sleeve extends coaxially through the vessel and has an upper sleeve end projecting through the upper vessel head, and is itself closed by an upper sleeve head. At the lower end, the sleeve is open, with the open end being located at an intermediate position in the vessel. An elongate firetube extends coaxially through the vessel and the sleeve, and projects through the upper sleeve head and through the lower vessel head, thus defining a chamber with the sleeve which surrounds the firetube. A burner is provided for injecting hot combustion gases into the firetube at the upper end. An oil inlet admits oil to the elongate sleeve, while a gas separator removes gas from the oil in the elongate sleeve. An oil outlet adjacent the upper vessel head removes oil from the vessel, and a water outlet adjacent the lower vessel head removes water from the vessel.

Abstract: A modular building system (100) including preformed extrusion-molded polymeric material (116). Parts include integral connector elements (160, 162) which can be slidably and snappingly reversibly interconnected to form the basic frame (102) and panel structures (108) of an overall building. The interconnected region permits limited ranges of angular as well as translational relative motion between adjacent, connected elements. Parts are assembled simply and quickly in the field, without requiring skilled labor or specialized tools, to form a functionally solid and stable building which responds to loads and temperature changes with yieldable, accommodating deformations that minimize the likelihood of building structural damage, and effectively transmit necessary loads to the ground via load-transfer paths through the building.

Abstract: Protein molecules (4a-4c, 10, 10a-10c) of interest are isolated and modified  into linearized protein molecules (10, 10a-10c). Individual protein molecule s are isolated for observation with hydrodynamic focusing apparatus (130), atomic force microscope (150), a separation plate (170), or the combination of isoelectric focusing gel (180), and electrophoresis gel (184). In the linearized protein molecule (10, 10a-10c) a first type of amino acid residue  (K) is labelled with a first tag (12), and a second type of amino acid resid ue (C) is labelled with a second tag (14). Tags (12, 14) impart a detectable se t of distinguishing characteristic ancillary properties (24, 34, 38, 44, 48, 5 2, 64, 68, 72, 120, 122, 206, 208, 210, 244, 246, 248) to the linearized protei n molecule (10, 10a-10c) that define the fingerprint thereof. Protein fingerprints are recovered as images (206, 208, 210, 244, 246, 248) by camer a (204) or fluorescence microscope (230), or as spectral analyses (24, 34, 38,  44, 48, 52, 64, 68, 72, 120, 122) by optical detector (15). Compilations of fingerprints for known protein molecules comprise fingerprint libraries to which the fingerprint of a protein molecule of interest is compared.

Inventor: STEPHENSON DALE D
IPC: A01K83/02

Abstract: A fishing lure comprising of two stationary barb-less wire hooks facing upwards and one movable barb-less hook facing downward which changes positions when tension is exerted on the fishing line by the fish caught on the hook ends. When a fish is insisting on going in the opposite direction this causes the barb-less wire hook to swivel on its connected axis, thereby expanding the stationary hooks and the swivel hook to spread wide apart. This makes it very difficult for the fish to open its mouth wide enough to escape the hold of the three barb-less hooks since they are now spreading open the fish mouth to its maximum. The barb-less, weed-less hooks make it very acceptable for releasing the fish if found not to be acceptable in size or species. By simply pressing on the back of the central barb-less hook, the sharp hook ends retract from their original holes without tearing or damaging the fish so as to be able to be released for future growth. Therefore this lure would be more humane in catch and release, which is becoming very popular and the law in many locations, and gives the fisherman a better chance of catching a fish and releasing it without serious damage with this device than with ordinary lures with barbs.
