Abstract: An apparatus is arranged to successively make plastic bags. The apparatus comprises a trapezoidal plate including a short edge having opposite ends from which opposite oblique edges extend divergently. The trapezoidal plate comprises a double walled structure in which clearance means is formed between walls. The apparatus further comprises drive means by which the trapezoidal plate is moved in a direction of height of trapezoi d so that the short edge can be engaged with the bottom gusset material. In addition, the apparatus comprises a pair of folding plates arranged to be engaged with the bottom gusset material and then inserted into the clearance means at positions corresponding to the oblique edges in accordance with the movement of the trapezoidal plate so that the bottom gusset material can be inserted into the clearance means by the folding plates to be folded into halves along the short edge and folded into the clearance means along the oblique edges. The bottom gusset material is then inserted between the pair of panel portions.

Patent CA-2428838-C (CA)
Inventor: HATFIELD PETER DOUGLAS
IPC: A01K97/02
Filed: 2003-05-15
Granted: 2005-08-02
Abstract: A bait container having one or more sections for the slow release of bait, which are separated by layers of water soluble material. In use, the bait container is lowered into the water, having at least one section for the bait accessible to the catch. The water soluble material then degrades over a period of time, permitting at least another section of bait to become accessible to the catch. In this manner, the water soluble material between the bait acts as a timed release, allowing the bait to fish longer. The unit can be placed in the water for long term fishing, or a peel back tab can be removed from the bait container so as to provide for the immediate release of the bait. The invention therefore provides a means to prolong the useful life of the bait, particularly bait for crustaceans such as lobsters and crabs.

Title: Hydraulic turbine with interblade vortex suppressor
Inventor: DEMERS ERIC
IPC: F03B3/12
Filed: 2003-08-07
Granted: 2011-05-10
Abstract: An improved Francis-type turbine runner. To extend operating range to partial load, inter blade fins partially extend into the flow paths between the runner blades. The inter blade fins correspond in shape and pattern with the shape and pattern of that portion of the runner blades with which the fins coextend along the flow paths between blades. The fins are recessed rearwardly of the flow dividing edges of the runner blades in the flow paths between the runner blades and reduce occurrence of inter blade vortices during partial or low load operating conditions. The shape of the interblade fins is further improved by tilting or sloping the tip of the interblade fin towards the suction surface of the adjacent blade. This creates a small convergence in the flow path between the fin and the suction surface of the blade.

Abstract: The interior window with integrated blind is a window adapted for use in a hospital setting to provide a patient with privacy in his or her hospital room while at the same time allowing a doctor or nurse to easily view the patient. The window includes: a substantially airtight encasement formed from two panes of glass that are secured to opposite sides of a spacer frame, a blind assembly encased within the airtight encasement, and a separate blind control extending from each of the two sides of the airtight encasement to allow for adjustment of the blind from either side of the wall in which the window is installed. The window is specifically dimensioned to fit in the glazing pocket of a window frame for a commercial building. An alternative embodiment, configured for areas of a hospital where control of the blind is appropriate from only one side of the window, includes only one blind control. This embodiment is identical to the first embodiment with the exception that one of the blind controls is missing.

Title: Color selection scheme for digital video watermarking
Inventor: ZARRABIZADEH MOHAMMAD HOSSEIN
IPC: H04N1/32
Filed: 2004-08-16
Granted: 2009-10-20
Abstract: Determining a chrominance portion to be watermarked employs a perception-based table that indicates for various pixel values which of the chrominance portions, if any, should be selected for watermarking. Only the Y, U, and V values of a pixel are needed to access the table and determine which chrominance portion should be selected. However, the table may be represented such that it may be accessed using only R, G, and B values. The table may be modified so that it may indicate which of U or V should be selected, or that neither should be selected, indicating that this pixel should not be watermarked at all. Advantageously, the table may be simplified by employing some processing, because a large section of the table may be replaced by a simple test on the pixel values, e.g., U<128, to determine the selected chrominance portion.

Title: Compositions, methods and kits for detection of an antigen on a cell and in a biological mixture
Inventor: SIEGEL DONALD L
IPC: C12N15/86
Filed: 2003-09-18
Granted: 2012-07-17
Abstract: The present invention relates to novel methods for detecting a member of a known binding pair in a sample, including a cell, where one member of the pair (termed the "receptor") is expressed by a bacteriophage, which phage is then used to detect the presence of the other member of the pair (termed the "ligand" or "target"). Rather than detecting the binding of the phage using antibody-based technology, the present invention relates to detecting the nucleic acid associated with the phage. In one aspect, the invention relates to identifying an antigen-bearing moiety (e.g., a red blood cell antigen) of interest present on a cell, e.g., a red blood cell, using antibody-displaying bacteriophage, as well as detecting anti-red blood cell auto- or alloantibodies and/or complement in a sample, using antiglobulin reagent-displaying bacteriophage and detecting a nucleic acid associated with the phage.
