Title: Boron neutron capture enhancement of fast neutron therapy
Inventor: GRIFFIN BRIAN R
IPC: A61N5/00
Filed: 1995-05-17
Abstract: Fast neutron therapy is significantly enhanced by irradiating target cells, either in vitro or in vivo with fast neutrons in the presence of a boron neutron capture agent having a plurality, and preferably at least nine, of 10B  atoms per molecule of the agent. In other aspects, tumor cells are treated in vivo by administering to a human or non-human animal a boron neutron capture agent having at least nine 10B atoms per molecule of the agent in an amount effective to associate the boron neutron capture agent with the tumor cells, and then irradiating the tumor cells with fast neutrons. Suitable boron neutron capture agents may be based on polyhedral borane anion derivatives, on derivatives that comprise two polyhedral borane anion cages linked together to form a structure comprising 20 boron atoms, on polyhedral carboranes such as compounds of the formulas closo-C2Bn-2Hn, closo-CBn-1Hn-, or nido-C2Bn-3Hn-, on oligomeric peptides constructed from boron-rich .alpha.-amino acids, or on boron enriched oligophosphates.
Patent CA-2195728-A1 (CA)
Inventor: LEWIS THOMAS E
IPC: B41C1/10
Filed: 1997-01-22
Abstract: Printing members resistant to handling damage include a porous compressible layer that deforms in response to applied forces, inhibiting overlying layers from tearing or scratching. One type of construction involves ablation-type printing members, wherein pulses from a heat source ablate one or more layers to expose (or facilitate exposure of by cleaning) an underlying layer. A second type of construction utilizes traditional photoexposure-type layers that harden or increase adhesion to adjacent layers in response to actinic radiation. The compressible layer is typically located below the radiation-responsive or imaging layer, but may also serve as that layer.

Title: Method and apparatus for automatically specifying a portion of text from a bitmap image of the text
Inventor: KNOWLTON KENNETH C
IPC: G06V30/10
Filed: 1995-06-07
Abstract: A document processing system (10) includes a user interface (22, 24, 25) and a memory (18) for storing bitmap data (18a) representing a document (14) that includes text. The user interface includes a display (22, 22a) for visualizing an image of the bitmap data and an input device, such as a mouse (25), for specifying locations within the displayed image corresponding to locations within the stored bitmap data. The document processing system further includes a bitmap data processor (20) that is responsive to a first specified location designating a start of an area of the image containing text to a second specified location designating a termination of the area of the image containing text, for processing bitmap data corresponding to the area. The bitmap processor operates to determine a lateral extent of lines of text within the area, to determine an amount of slope, if any, of the lines of text within the area, to determine a center-to-center spacing of the lines of text within the area, and to determine a location of a top line of the text. That is, the bitmap processor operates to refine the boundary of the area specified by the input device so as to provide a geometric specification of all text appearing within the bitmap data that corresponds to the originally specified area. The bitmap processor preferably operates to first laterally compress the bitmap data prior to operating on same.

Filed: 1996-06-24
Abstract: A furniture drawer (10) is constructed by providing a generally flat, elongate metal body member (12) and manually bending the member to form a rear wall (54) and a pair of side walls (56). Bending of the body member (12) to form corners (50, 52) at the juncture of the side walls (56) and rear wall (54) is facilitated by transverse coined indentations (48) in the body member (12) which create lines of weakness in the body (12) for accurately locating the corners (50, 52). The body member (12) is also formed with channels (18, 20, 26) for receiving drawer slides and for receiving a bottom panel. Flanges (30) formed at forward ends of the body member (12) provide for attachment of a suitable drawer front (14). The drawer assembly as thus designed is capable of being economically packaged flat and shipped for easy assembly by the consumer.

Patent CA-2200101-A1 (CA)
Inventor: SCAPPATURA DOMINIC E
IPC: B01D53/62
Filed: 1997-03-17
Abstract: This invention, when employed, will result in the elimination of specific contaminants, reduce heat and vapours from the emissions of an internal combustion engine. This system consists of a baffled heat exchanger which receives its cooling ability from the existing air conditioning unit of the automobile and drastically reduces the exhaust temperature so that vapours are condensed to a liquid and gases are cooled. The products of the cooling process can now be treated in the trap with a chemical which neutralizes the acids and removes exhaust residues. The liquid excess flows into a holding tank while the balance of the exhaust is then forced upwards through a chemical field extruding acid compounds prior to leaving the trap. An intake valve is installed before this phase to prevent any vacuum that may form by the acceleration or deceleration of the automobile. The bubbler components specifically reduce carbon dioxide and carbon monoxide from the remaining exhaust fumes resulting in a cool clean exhaust after leaving the bubblers, the exhaust then passes through another neutralizing unit followed by a blocker which closes when the system is not in use.          The components of the waste material can be recycled and sold.

Abstract: An end hook for a power return tape measure includes a shank having a longitudinal axis and a catch extending from the shank at an angle to the longitudinal axis. The shank being arcuately shaped about the longitudinal axis, and has a plurality of rivet mounting holes, the mounting holes positioned on each side of the longitudinal axis and spaced laterally from the longitudinal axis. The fastening holes of the shank have a greater longitudinal spacing than mounting holes in a measuring tape so that movement of the end hook longitudinally toward an end edge of the free end of the measuring tape during a collision in power return causes the holes in the end hook nearest the end edge to contact the fasteners before the holes furthest from the end edge.

Abstract: A cooking apparatus to facilitate straining requirements. The cooking apparatus includes a pot and lid that can be securely integrated to function as a strainer. The lid includes a circumferentially extending flange that is designed to slide into the pot and rest on the rim of the pot. The flange includes a pair of opposing perforation regions and a pair of opposing protrusion elements.
