Publication number: 20050109999Abstract: A fencing system includes a rail having at least two metal wires ensheathed in a plastic web, an end connector having a face plate with two slots and a middle portion separating the two slots, the end connector having a front side and a rear side. A free end of the rail is disposed in the slotted end connector so that the rail runs from the front side of the connector through a first slot, around the middle portion, and then back through a second slot. A fastener pivotally attaches the end connector to a fence post. Also, a joining connector of similar construction as the end connector is used to secure the free ends of two rails. Methods for securing a rail to a connector and for securing the free ends of two rails to a joining connector are also disclosed.Type: ApplicationFiled: November 21, 2003Publication date: May 26, 2005Inventor: John Wall

Publication number: 20050099451Abstract: An inkjet printhead includes a housing defining an interior compartment. The housing includes a front or print face which presents an array of nozzles that are adapted to project drops of ink on a substrate as the substrate passes in front of the array. The front face defines a front air passage that surrounds at least a portion of the nozzle array to allow air flow between the exterior of the housing and the interior compartment. The housing defines at least one additional air passage constructed to allow air flow between the exterior of the housing and the interior compartment. The air passages are constructed to create positive air flow through the front passage which reduces the accumulation of debris around the orifice array. The printhead may also include a protective structure that extends across a portion of the front air passage to protect the orifice array from being damaged by materials, such as mail, that move past the printhead at high speeds during the printing operation.Type: ApplicationFiled: November 2, 2004Publication date: May 12, 2005Inventors: Kevin Kuester, Jack Heller, John Wall

Publication number: 20040175027Abstract: A machine vision system has an illumination head (1) with seven rings of LEDs 2-8, each having a different elevational angle. Each ring is configured with a particular current level, thereby setting its intensity. Rings 3 and 4 are green and blue, the other rings being red. A controller controls illumination by varying one or a combination of elevation, azimuth quadrant (or 45° octant), intensity, and colour. For example an image may be captured with fully surrounding, North quadrant, South quadrant, East quadrant, and West quadrant illuminations. Alternatively, there may be both North-South illumination for one image and East-West for another.Type: ApplicationFiled: March 5, 2004Publication date: September 9, 2004Inventors: James Mahon, John Wall, James Tracey, Mark Dullaghan, Sean Doherty
