Publication number: 20030047297Abstract: A pre-treatment device for wood chips for pulping comprises a tube through which the wood chips fall into a digester. Steam is injected into the tube through rings of nozzles, which are angled circumferentially to impart a rotary and turbulent motion to the falling chips. Some nozzles are angled downwardly to encourage the chips to flow freely through the tube, some are horizontal to encourage a longer dwell time near the nozzles. Digesting liquor is also sprayed onto the chips from spray nozzles after the first ring of steam nozzles. The heat and steam expel air and other non-condensable gases and volatiles from the chips, allowing them to absorb the liquor. At the bottom of the tube, the chips are propelled down and outwards by jets of higher-pressure steam, spreading and packing them into the digester.Type: ApplicationFiled: August 23, 2002Publication date: March 13, 2003Applicant: Jack T.

The arms rotate about their respective medial connections, thereby forcing the ends that rotatably connect to the driver tool to move in a vertically opposite direction than the weight.Type: ApplicationFiled: July 26, 2002Publication date: March 13, 2003Inventor: Jake Merrick

Publication number: 20030047333Abstract: A hand-held pneumatic rotary drive tool having an adjustable exhaust. The tool has an elongate housing containing a pneumatic motor. The housing has an inlet passage for pressurized air at the rearward end of the housing and air delivery passaging for flow of pressurized air to the motor. A rotary connector on the housing at the inlet passage permits connection to an air hose. The housing also has an air exhaust passage for exhausting air from the motor. An air deflector for exhausting air exiting the exhaust passage is rotatable around the connector for deflecting exhaust air laterally outward in a selected direction away from a user holding the tool.Type: ApplicationFiled: October 18, 2002Publication date: March 13, 2003Inventor: Osuma Izumisawa

Publication number: 20030047335Abstract: A soft-touch pneumatic drive unit for welding is provided. The drive unit includes a first section, a second section, and a third section. A piston rod extends substantially throughout these sections and contains a drive piston in the second section and a second drive piston in the third section. Pressurized fluid is supplied through the first section and into the second section to provide a driving force on these pistons. Cushioning fluid is supplied through the first section to the second section to cushion and slow the piston rod as an electrode carried thereby is moved toward a workpiece. A floating piston in the second section then blocks the flow of cushioning fluid from the first section with fluid pressure in the second section then decreasing to atmospheric pressure to enable full welding force to be applied through the drive pistons and the piston rod to the electrode. The cushioning fluid also aids in returning the piston components to the retracted position upon the completion of a weld.Type: ApplicationFiled: December 8, 2000Publication date: March 13, 2003Applicant: Doben LimitedInventors: Tam C.

Publication number: 20030047339Abstract: A semiconductor device (e.g., a chip scale package or CSP) is described including multiple input/output (I/O) pads arranged on a surface of a semiconductor substrate, a compliant dielectric layer, an outer dielectric layer, and multiple electrically conductive, compliant interconnect bumps (i.e., compliant bumps). The compliant bumps may form electrical terminals of the semiconductor device. The compliant dielectric layer is positioned between the outer dielectric layer and the surface of the semiconductor substrate. The outer dielectric layer and the compliant dielectric both have multiple openings (i.e., holes) extending therethrough. Each of the compliant bumps is formed upon a different one of the I/O pads, and extends through a different one of the openings in the first compliant dielectric layer and the outer dielectric layer. Each of the compliant bumps includes an electrically conductive, compliant body, and an electrically conductive, solderable conductor element.Type: ApplicationFiled: September 12, 2001Publication date: March 13, 2003Inventor: Michael A.
