Patent number: 4497275Abstract: A composite stamp pad for coating a stamping device with ink. The composite stamp pad is composed of a porous ink pad with a porous reservoir liner. The porous reservoir absorbs any ink which may leak from the pad due to heat or high humidity. Ink absorbed into the reservoir flows back into the pad automatically when temperature or humidity return to moderate levels. The reservoir and ink pad each have an open cell structure wherein the average pore diameter of reservoir is at least about 10 micrometers greater than the average pore diameter of the pad.Type: GrantFiled: September 26, 1983Date of Patent: February 5, 1985Assignee: Dennison Manufacturing CompanyInventors: Lewis H. Johnson, Lee A. Carlson, David M. Lunt

Patent number: 4484827Abstract: A disposable ink cartridge for use in automatic marking systems. The ink cartridge is composed of a housing which contains a collapsible elastomeric ink reservoir having an open end secured to a plurality of barrier disks. The barrier disks are apertured to permit passage of ink through and between them, from the reservoir. An ink absorbing member of fibrous or porous material is positioned at the other, outlet end of the cartridge housing. The ink cartridge provides a constant flow of ink when the ink absorbing member is contacted by a print head or the like until the supply of ink is depleted from the reservoir. The cartridge design permits depletion of essentially the entire reservoir under the above conditions.Type: GrantFiled: February 7, 1983Date of Patent: November 27, 1984Assignee: Dennison Manufacturing CompanyInventor: Lewis C. Price, Jr.

Patent number: 4458625Abstract: An apparatus for fixing a toner image by transporting a toner image bearing material as it is held between a fixing roll and a compression roll. In the apparatus, which is positioned above the fixing roll, a release agent having a viscosity of 50 to 100,000 cS is applied onto the surface of the fixing roll through a porous fluorocarbon resin membrane having a pore size of 0.01 to 10 .mu.m, a porosity of 35 to 85%, and a thickness of 50 .mu.m to 1 mm. The porous membrane may be located on the inner surface of the bottom of a tank containing the release agent above an opening in the tank bottom.Type: GrantFiled: April 28, 1981Date of Patent: July 10, 1984Assignee: Sumitomo Electric Industries, Ltd.Inventors: Isamu Sakane, Chiaki Kato

Patent number: 4394844Abstract: An apparatus for applying an epoxy glue, solder paste or a similar material to the surface of a planar circuit chip, such as a silicon integrated circuit chip. Positioned just above the liquid epoxy in the bath is a fine mesh, stainless steel screen clamped at its periphery and having supported thereover a leveling paddle with a micrometer adjustment rotatable relative to the bath itself for smoothing the material over the screen surface. After this smoothing or leveling operation, the chip, usually held by a vacuum chuck, is pressed against the screen into the epoxy with the screen functioning as a resilient means enabling the chip to be withdrawn therefrom with uniform deposition of material applied to the undersurface thereof. The apparatus may also have a spongy material such as polyurethane or a sponge neoprene rubber under the screen to enhance chip removal.Type: GrantFiled: January 7, 1982Date of Patent: July 26, 1983Inventors: Laurior A. Wood, Donald N. Humphries

Patent number: 4387002Abstract: An adhesive discharge device for use with adhesive which sets by the evaporation of a solvent. The device incorporates a valve-controlled discharge nozzle for intermittent discharge of adhesive on a cycle basis. Drying of adhesive around the nozzle opening when the valve is closed and the discharge of adhesive is interrupted is prevented by a movable closure cap containing a solvent vaporizer. The closure cap is movable into a position enclosing and sealing the nozzle opening, and the vaporization of solvent inside the closure cap around the nozzle opening prevents the drying and encrustation of adhesive.Type: GrantFiled: August 16, 1982Date of Patent: June 7, 1983Assignee: Maschinenfabrik Alfred Schmermund GmbH & Co.Inventor: Siegfried H. Knecht

Patent number: 4336767Abstract: An ink transfer device comprising an ink transfer surface layer which may be connected to a porous ink storage body, such as used in a printing device or apparatus, having a porous structure with continuous pores therein and 8 to 30% porosity, and a surface ruggedness of less than 20 microns and ink mobilizable and storable porous ink storage body. The structure of the ink transfer surface layer and the ink storage body are produced respectively and successively by heat compression in a mold, thermoplastic powder of less than 50 microns diameter and of a little larger than the former ones. The inventive ink transfer surface layer enables uniform and efficient transfer of ink from the device even after repeated impressions of the device.Type: GrantFiled: August 6, 1979Date of Patent: June 29, 1982Assignee: Bando Chemical Industries, Ltd.Inventor: Hiroshi Wada

Patent number: 4322172Abstract: In a printer, an arrangement for transferring ink from a container carrying ink through an exposed wick to an inked ribbon movable on a roller and housed in a replaceable cartridge. Engaging means are provided on the container, which when the container is inserted into a slot in the wall of the cartridge causes the engaging means to lock on to the cartridge wall by the pressure of a spring. The spring action locks the container to the cartridge as well as moving an exposed wick carried by the container against the ink ribbon for inking purposes.Type: GrantFiled: June 16, 1980Date of Patent: March 30, 1982Assignee: General Electric CompanyInventor: Edward D. Furrow

Patent number: 4302277Abstract: A device for labeling flat objects, such as compact cassettes, video cassettes or the like with a supply stacker for the transfer of label holder-arranged labels. The label holders are provided with vacuum impingeable suction bores for label transfers and with object recess-and label perforation-and border-matching beveled projections, plus a device for effective label adhesion. The device includes a radially-mobile arrangement of label holders on at least one step-by-step revolving rotary-run head. The holders move from the head to stationary functional stages, namely, a transfer stage, where the label is made to stick, and an applicator stage for applying labels to objects. A conveyor chain is provided for continually passing by the rotary-run head with object sliding cams. The applicator stage is equipped with a platform for lifting objects from the continuous-run conveyor chain above the level of the cams.Type: GrantFiled: June 12, 1979Date of Patent: November 24, 1981Inventor: Heino Ilsemann
