Inventor: RAZ RYAN S
IPC: G06T7/40
Filed: 1996-07-18
Abstract: A window texture extraction process for quantifying texture features in greylevel images and combining the quantified texture features with previously derived classification results. The previously determined classification results require that all of the training data and all the target data be assigned, or be capable of being assigned to one of two classes. The result is a set of new features that can be quickly analyzed to determine such properties as class membership for identification purposes. In order to foldin the classification results, the class membership is established in previous experiments on images which have been characterized. The previous experiments are executed through the application of a window texture extraction kernel according to the invention.

Abstract: A structured packing is disclosed.  The structured packing has a plurality of packing elements stacked together as "building blocks" to provide the packing for an exchange column. Each packing element comprises a polyhedron (e.g., a cube) having a plurality of edges formed by elongated rods. At least one transfer sheet is disposed within the polyhedron (e.g., a cube), wherein the first end of each transfer sheet connects to a different edge of the polyhedron and the second end of each transfer sheet connects to another edge of the polyhedron. In one embodiment, the intersection of the transfer sheets forms two pyramids within the cube-shaped packing element, the bases of the pyramids being opposite sides of the cube and the spices of the pyramids intersecting substantially at the center of the cube. In the preferred embodiment, at least one side of each pyramid is open and the other sides of the pyramids formed by the intersecting transfer sheets provide flow surfaces within the packing elements.  The elements allow great flexibility in the manner and relative orientations in which the elements can be packed together, allowing great design freedom to manufacturers and users of exchange columns.

Title: Arc fault detector with limiting of sensed signal to shape response characteristic and circuit breaker incorporating same
Inventor: MACKENZIE RAYMOND WARREN
IPC: H02H1/00
Filed: 1998-09-28
Abstract: An arc fault detector having a pulse generator generating a pulse each time an arc is struck includes a limiting amplifier which limits the amplitude of the pulses to discriminate against false trips from sizable singular events such as tungsten bulb burnout and turn-on of a cold tungsten lamp controlled by a phased back dimmer. When a time attenuated accumulation of the pulses reaches a predetermined level an arc fault signal which can be used to trip the circuit breaker is generated. The pulse generator of the arc fault detector includes multiple stages of high pass filtering which produces overshoot and therefore additional pulses each time an arc is struck. As only the additional pulses associated with large amplitude arcs exceed a threshold value for inclusion in the time attenuated accumulation, compensation for the reduction in sensitivity to large amplitude arcs imposed by the limiting amplitude is provided.

Inventor: JONES JOHN WILLIAM
IPC: B41N1/24
Filed: 1998-09-23
Abstract: A screen printing stencil  is produced chemically by application of a chemical agent 5 to a screen mesh 3 having a  stencil-forming layer.  The chemical agent 5 is applied dropwise using computer-controlled apparatus.  The chemical agent reacts with the stencil-forming agent to harden the stencil in areas which remain upon subsequent wash-out.  The stencil so produced can be used for screen printing in the usual way.  The method avoids the use of safe lights and actinic radiation.  The apparatus used can be a commercially-available apparatus designed for direct application of liquids dropwise to screens  mounted in their frames.  The stencil-forming layer can be provided using a commercially-available emulsion-coated film or a commercially-available emulsion applied directly to the screen mesh.

Title: Amplified pressure air driven diaphragm pump and pressure relief valve therefor
Inventor: PASCUAL WILFRED DAVID
IPC: F04B43/073
Filed: 1997-05-01
Abstract: An air driven diaphragm pump having two opposed pumping cavities (26). A  center section assembly (104) between the pumping cavities includes a cylinder (108) and a power amplifier piston (124). The power amplifier piston as well as the diaphragms (88) are coupled with a common control shaft (116). A valve assembly (138, 144) is arranged with a manifold (162) to receive pressurized air and distribute that air in alternating fashion to the sides of the power amplifier piston as well as to each of the diaphragms. By directing pressure to a side of the power amplifier piston facing the same direction as the diaphragm receiving pressure, an amplified pressure on a pump chamber is experienced. With the power amplifier piston being approximately twice as large as the diaphragm assembly an amplification of three times the pressure on the pump chamber is experienced. Both pump chambers are able to operate to pump material.

Title: A method and a system for deicing of airfoil wings of composite material
Inventor: GRABAU PETER
IPC: F03D80/40
Filed: 1997-07-03
Abstract: For avoiding icing of windmill wings of composite materials, use is made of microwave energy for heating of the composite material itself, this energy preferably being supplied from interior, fixedly mounted microwave generators in response to detection of potential climatic conditions for icing to occur. The wing surface can be coated with a layer reflecting the microwaves, whereby these may propagate by reflections through and between the shell parts of which the wing will normally consist. It is possible to arrange for selective heating by the use of more generators, which may then, each, be of the type that is already in production with modest size and at low costs for use in ordinary microwave ovens.
