Title: Method of lithographic imaging with reduced debris-generated performance degradation and related constructions
Inventor: LEWIS THOMAS E
IPC: B41C1/10
Filed: 1999-03-11
Abstract: The performance-limiting effects of thermal breakdown on ablation-type lithographic printing plates are overcome by rendering the ink-accepting surface largely impervious to the effects of debris originating with the surface layer of the printing member, or by discouraging the formation of harmful debris altogether. In one approach, the ink-accepting surface is a highly crosslinked polymer. The resulting cured matrix exhibits a sufficient degree of three-dimensional bonding to resist melting, softening, or chemical degradation as a result of the imaging process. Alternatively, an intervening layer, disposed between the imaging layer and the surface layer, prevents the surface layer from undergoing significant thermal degradation in response to imaging radiation or ablation of the underlying imaging layer, and is also formulated to produce little debris or debris having an affinity for ink and/or fountain solution similar to the affinity of the substrate --e.g., which does not reduce the oleophilicity of the underlying ink-accepting surface. Following imaging, the remnants of the insulating layer are removed along with the surface layer where the plate received imaging radiation.
Patent CA-2265433-A1 (CA)
Inventor: NEWMAN DAVID E
IPC: B29C67/20
Filed: 1999-03-16
Abstract: The present invention relates to microporous and ultrafine polytetrafluoroethylene (PTFE) membranes of high permeability, excellent mechanical strength, and good chemical inertness, and to methods for their preparation. According to the method of the present invention, a porous PTFE substrate having a first pore rating is compressed to provide a porous membrane having a second pore rating, wherein the second pore rating is smaller than the first pore rating. The PTFE substrate can be contacted with one or more fibrous sheets during the compression step, which is preferably performed by passing the substrate, and fibrous sheets, if appropriate, between two calender rolls. The resulting porous PTFE membrane then can optionally be stretched and/or sintered, and preferably has a water permeability of at least about 0.5 1/hr/m2/kPa.

Title: Hydrophilic finish for textiles
Inventor: RODRIGUES KLEIN A
IPC: D06M15/27
Filed: 1999-03-19
Abstract: An improved textile material having a hydrophilic finish which is made by a method comprising applying to a fibrous web an aqueous solution comprising an anhydride based graft copolymer, and drying the fibrous web at a temperature sufficient to cure the anhydride based graft copolymer in the fibrous web. The anhydride based graft copolymer is the reaction product of an ethylenically unsaturated monomer, an anhydride monomer selected from malefic anhydride and itaconic anhydride, either a monofunctional polyglycol having a hydroxyl or amine terminal group on a polyfunctional polyglycol having a weight average molecular weight of greater than 5,000 and at least one terminal hydroxyl group, and a free radical initiator. The hydrophilic finish eliminates the shortcomings inherent in certain textile materials such as their high affinity for oils, staining during washing, static cling problems, and wearer discomfort.

Patent CA-2268221-A1 (CA)
Inventor: O'CONNELL JAMES M
IPC: B44F7/00
Filed: 1999-04-01
Abstract: An imaging system and method for creating a three-dimensional illusion. The imaging system includes a lighting source and a recessed surface formation.   The recessed surface formation is a three-dimensional object having recessed sections and raised sections The placement of the lighting source and recessed surface formation is designed so that a viewer looking at the recessed surface formation from a specific, predetermined vantage point within a range of viewing angles will perceive an inversion of the recessed sections and raised sections with respect to one another. As the viewing angle becomes more acute, the recessed surface formation will appear to tilt towards the viewer. The method includes the steps required so as to produce the three-dimensional illusion. A reflective coating on the recessed surface formation, specifically the sidewalls thereof, is used to enhance perception of the illusion. Raised sections for casting shadows are equally important in defining form for the illusion.

Title: Methods for the processing of underutilized hard-shelled crustaceans
Inventor: GALLANT CYRIL G
IPC: A22C29/02
Filed: 1999-09-24
Abstract: Methods are provided for separating the intact shell of hard-shelled crustaceans from the raw edible meat contained therein which is very strongly attached to the shells. The methods each include the first step of initiating the detachment of the raw edible meat from the intact shell by the step of subjecting the intact shell to at least one freeze-thaw cycle, where the thawing is carried out in cold water or cold brine to minimize deterioration of the flavour of the crustacean meat. Then the intact shell is separated from the raw edible meat by several different alternative steps. One alternative step includes subjecting the so-treated intact shell to vacuum aspiration to separate the intact shell from the raw edible crustacean meat, so as to recover the raw edible crustacean meat. Another alternative step includes manually separating the intact shell from the raw intact edible crustacean meat, so as to recover the raw intact edible crustacean meat from the intact shell. These methods are applicable to the recovery of raw edible crustacean meat from underutilized portions of hard-shelled crustaceans. These methods may also be used for the recovery of raw edible intact crustacean meat from hard-to-process hard-shelled crustaceans, e.g., Spiny lobster, Northern Stone crab (Lithodes maja), Porcupine crab (Neolithodes grimaldii), Irish crab (Cancer pagurus) and Jonah crab (Cancer borealis).
Patent CA-2283700-A1 (CA)
Inventor: HERBERT PETER
IPC: B27B5/34
Filed: 1998-03-16
Abstract: The invention relates to a cutting device for wood or other materials, comprising a saw blade clamping device for fixing circular saw blades radially and/or axially, said circular saw blades being mounted on a drive shaft in such a way that they can be moved axially. According to the invention, axially moveable individual carrying bodies are provided on said drive shaft (1) for at least one circular saw blade, e.g. (2a). Said circular saw blades, e.g. (2a) are moved axially by means of conveying spindles, e.g. (7) which run parallel to the drive shaft axle and penetrate said carrying bodies, e.g. (3). At least one clamping element (21) is positioned in the drive shaft (20). The campling element (21) is arranged so that it is radially movable. In the first stage, the circular saw blades, e.g. (2a) positioned on the carrying bodies (3) are moved by means of the clamping element (21). In the second stage, the circular saw blades, e.g. (2a) or carrying bodies e.g. (3) are connected to the motor shaft in such a way that they have a positive and/or nonpositive fit. The inventive device enables the width of the saw cut to be adjusted without the saw blades having to be disassembled, such disassembly being time and labour consuming. The carrying bodies for the circular saw blades are narrower than conventional moving heads for multiple-blade circular saws, with the result that a larger number of circular saw blades can be mounted on one axle.
