Patent number: 5792322Abstract: A Y-shaped flow splitter passes papermaking fluid with some fibers with reduced clogging and has a flat surface opposite the leg of the Y where the flow divides into the two arms of the Y. A generally flat rectangular surface is positioned opposite the leg of the Y of the flow splitter which divides the flow evenly without providing a place for fibers to collect and thus clog the flow through the splitter. The splitter allows the flow to a pair of dilution tubes to be controlled by a single valve with a single flow passage reducing clogging and valve cost. The flow splitter is constructed of stainless steel by a by casting process. A process known commercially as the Extrudehone process is used to produce smooth flow passages.Type: GrantFiled: December 3, 1996Date of Patent: August 11, 1998Assignee: Beloit Technologies, Inc.Inventors: Richard E.

Patent number: 5783045Abstract: In a twin wire former a headbox injects stock onto a forming wire with which a second forming wire is brought into gradual engagement. A forming shoe directs the two wires along a path of increasing curvature, above which water is drained by adjustable auto slices. The two wires with the web therebetween then follow an oscillating S-shaped path between seven S-rolls and are directed upwardly through three individually loaded press rolls with increasing pressure to about four hundred and fifty pounds per linear inch at the last wet press. Drainage pans collect water from the upper surface of the twin wires and water thrown off the upper press rolls. The press rolls are individually pneumatically pivotable to increase nip pressure, and collectively pivotable to open all the nips. Next a high pressure dry nip can increase the fiber content of the web to thirty-five percent fiber.Type: GrantFiled: May 6, 1996Date of Patent: July 21, 1998Assignee: Beloit Technologies, Inc.Inventors: Gilmar M.

Patent number: 5762759Abstract: A papermaking machine uses a low pressure water jet mounted on a pneumatic actuator for movement at least as fast in the cross machine direction as the paper web moves in the machine direction for a distance of 2 to 12 inches. The jet rapidly cuts a tail with a blunt edge of 2 to 12 inches wide from the web. The actuator is mounted on a screw or belt driven carriage to traverse the web and expand the tail after it has been threaded through the dryer section until the tail encompass the entire web and thus completes the threading process. A controller coordinates an air jet positioned beneath a doctor blade and a vacuum suction roll which engages the last press roll. The air jet and vacuum suction roll are actuated when the blunt end of the tail engages the doctor blade. In this way a tail with little or no streamer is formed and blown onto a dryer fabric supported on a vacuum suction roll which leads the tail into a single tier dryer section.Type: GrantFiled: January 27, 1997Date of Patent: June 9, 1998Assignee: Beloit Technologies, Inc.Inventor: Gregory L.

Patent number: 5741062Abstract: A flashlight outer sleeve is formed of rubber which has an integral camouflage pattern. Because the multicolored elements of the sleeve are fused together, a scratch or abrasion will not appreciably alter its appearance. The rubber sleeve is formed in a compression molding process. Multilayer rubber sheet assemblies are prepared for the compression molding process by first die-cutting camouflage pattern shapes from thin sheets of rubber of two or more colors. The die cut shapes are placed on rectangular base sheets and pressed into temporary engagement to create multilayer sheet assemblies. The sheet assemblies are disposed in conventional rubber compressing molding molds and are heated. As the base sheet and the pattern shapes are comprised of identical rubber material, except for color, the heated rubber flows such that the multilayer assemblies take on the shape of the molded parts.Type: GrantFiled: August 16, 1996Date of Patent: April 21, 1998Assignee: Rayovac CorporationInventor: Stephen Shiu-Fai Man

Patent number: 5738007Abstract: A calender employs an open-stack like arrangement with a single vertical beam or support column on each end of the calender. In combination with the support beam, a special swing link is used to support tension loads on the open side of the calender. The nip is thus straddled by structural members between the support column and the link. This combination has the ability to support high linear nip loads, as high as 3,000 PLI or higher. The link has pin connections at both ends so that when one pin is removed, the link can be swung open for roll removal or accessibility. Thus, the strength of the closed-stack calender is combined with the visibility and ease of access of the open-stack calender by the employment of tension links which replace one of the support columns utilized in a closed-stack calender.Type: GrantFiled: March 12, 1996Date of Patent: April 14, 1998Assignee: Beloit Technologies, Inc.Inventors: Arnold J.
