Patent number: 6792831Abstract: The tools (wrenches) of this invention provide a one color instant identification of color coded tools. Preferably, the tools have a portion of their outer surface colored. Typically, the color impregnates the metal or plating during the manufacturing process. Another embodiment is a colored applique, band or sleeve on the outer surface of the tools. The key of this coloring is to identify the tool quickly by coloring a large area of the tool. This provides for quick identification of the tool even if the numerical designations are illegible because of small sizing or dirt obliteration. In a preferred embodiment, virtually the entire tool is colored during manufacturing. In another preferred embodiment, large raised numbers combine with the overall color scheme to make the tools quickly identifiable. Dirting the large colored surface is very unlikely as is obliterating the large raised fractional numbers.Type: GrantFiled: February 21, 2002Date of Patent: September 21, 2004Inventor: Larry G. Crosser

Patent number: 6792857Abstract: An apparatus and method for storing rubber-covered cylinder sleeves for offset printing for rotary printing machines permits an identified rubber-covered cylinder sleeve to be found easily. The apparatus is equipped with an electronic memory device into which, for each rubber-covered cylinder sleeve, characteristic data can be entered and stored. As the rubber-covered cylinder sleeve is introduced into a storage, the characteristic data from the rubber-covered cylinder sleeve are read into the memory device, and the rubber-covered cylinder sleeve can be removed from the storage apparatus in accordance with predefined data.Type: GrantFiled: October 9, 2001Date of Patent: September 21, 2004Assignee: MAN Roland Druckmaschinen AGInventors: Christian Sameit, Georg Schmid

Patent number: 6792859Abstract: A rotating drum in which, when the rotating drum is rotated at high speed, there is no offset between divisional drum parts, there is little imbalance, and a moment of inertia for rotation is small. A drum main body is divided into four drum parts whose cross-sectional configurations orthogonal to an axis are fan-shaped. Female projecting portions and male projecting portions are formed at a pitch dimension having a predetermined fit-together tolerance. Thus, the drum parts can be assembled together with a certain amount of leeway at a time of assembly. After the four drum parts have been assembled together, wires are press-fit in from an end surface side of the drum main body so as to tightly fasten the drum parts. Because the assembled drum main body defines configurations of the drum parts to have point symmetry, imbalance can be made small.Type: GrantFiled: February 27, 2003Date of Patent: September 21, 2004Assignee: Fuji Photo Film Co., Ltd.Inventors: Takashi Fukui, Akihiro Hashiguchi, Mitsuhiro Kitano, Tugio Fukasawa

Patent number: 6792860Abstract: A packing is pressed against a surface of a cylinder by using at least one roller which is deployed and retracted with respect to the cylinder by an adjusting mechanism. A guard is provided for covering the roller. The guard is actuated by the roller adjusting mechanism. The guard covers the roller in the direction of the cylinder and is actuated with the roller.Type: GrantFiled: November 15, 2002Date of Patent: September 21, 2004Assignee: Koenig & Bauer AktiengesellschaftInventors: Norbert Edmund Schröder, Andreas Ewald Heinrich Bernard, Karl Robert Schäfer

Patent number: 6792861Abstract: An image recorder of an external drum type includes a feed/discharge unit located above a drum and having an upper tray and a lower tray. The upper tray is inclined so that an edge thereof on the front side of an image recorder body is downward or at a lower level. For placing a plate on the upper tray, the plate is fed over the lower edge of the tray onto the tray. The upper tray has a movable suction pad for raising the plate. The image recorder of the external drum type can easily feed a large-size image recording material or plate over an upper edge of the inclined tray onto the tray.Type: GrantFiled: March 17, 2003Date of Patent: September 21, 2004Assignee: Dainippon Screen Mfg. Co., Ltd.Inventors: Kazuma Kan, Ryuuzo Tokimasa

Patent number: 6792863Abstract: A printing apparatus has a manual control mode. The manual control mode has a proportion indication, a proportion adjustment key, a selected range adjustment key, and region selection keys. In the manual control mode, an operator selectively touches the region selection keys to select a region in which an ink key opening is to be changed. Next, the operator touches the selected range adjustment key to change the ink key opening of the selected region. The ink key opening is increased or decreased by the percentage indicated at the proportion indication the number of times the selected range adjustment key is touched. The settings made in the manual control mode are stored in a storage section, and are used to control the amount of ink supply during automatic control. Thus, the printing apparatus having the function of automatically controlling the printed density can make partial tone changes.Type: GrantFiled: October 9, 2002Date of Patent: September 21, 2004Assignee: Dainippon Screen Mfg Co., Ltd.Inventors: Takaharu Yamamoto, Nobuhito Kohara, Shigeo Murakami

Patent number: 6792864Abstract: The present invention provides a method for reproducing image data from a press output on another device. The present invention mimics color, resolution and frequency of dots used by varying the color saturation (amplitude) of the dots used to mimic the defining characteristics of the source output. By allowing adjustments in both frequency and amplitude to vary from the original output device, it becomes possible to match the resolution and color of the source device.Type: GrantFiled: January 3, 2003Date of Patent: September 21, 2004Assignee: Eastman Kodak CompanyInventors: Michael J.
