Patent number: 5620514Abstract: A magnetizable layer can be applied to a flexible backing web by gravure coating at high speeds by independently driving the backing web at a speed that is substantially different from the surface speed of the gravure roll. Especially high coating speeds have been achieved when the gravure roll rotates oppositely to the direction in which the backing web is advancing. In one embodiment, a nip roll presses the backing web against the backup roll, there is a gap between the gravure roll and a backup roll, and an idler roll is positioned downstream of the gap to force the backing web into contact with the gravure roll over a short arc. When that backup roll has a hard surface such as metal, its surface can be machined with precision, and that precision can be maintained in spite of exposure to solvent vapors.Type: GrantFiled: September 1, 1995Date of Patent: April 15, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: John D.

Patent number: 5565033Abstract: A method of applying bonding agents, such as solder pastes and conductive adhesives, to pad sites in the manufacture of electronic circuits uses a paste injection head. A permanent mask with cavity openings is applied around conductive pads on a carrier. The conductive pads correspond to chip attachment sites. The injection head is brought into contact with a surface of the mask, and pressure is applied to a bonding agent in the injection head. The injection head is then moved over the surface of the mask, filling cavity openings with the bonding agent. The injection head is then removed from the surface of the mask. If a solder paste is used, infrared radiation is applied to filled cavity openings to evaporate a paste flux and reflow solder to form solder balls within the cavity openings projecting above the mask. If a conductive adhesive is used, a stencil is applied to the surface of the mask prior to contacting the mask with said injection head.Type: GrantFiled: May 24, 1995Date of Patent: October 15, 1996Assignee: International Business Machines CorporationInventors: Michael A.

Patent number: 4619842Abstract: An advancing optical fiber (22) is marked with a plurality of spaced indicia along its longitudinal axis. The indicia are applied by an applicator wheel (56) in the form of a disc which is mounted for rotation about an axis which is transverse to the path of travel of the optical fiber. The wheel has a plurality of marking teeth (70-70) arranged about its periphery with each tooth provided with a groove (72) for receiving increments of length of the optical fiber as it is moved rotatably. As the wheel is turned, each tooth in seriatim compresses a porous, resilient pad (80) which is disposed to one side of the wheel in a chamber through which the optical fiber is advanced to cause ink from the pad to be received in the groove of each tooth. Further rotation of the wheel causes ink to be transferred from each groove to the moving fiber. The pad is supplied with ink through a tube by a peristaltic pump (90).Type: GrantFiled: March 28, 1985Date of Patent: October 28, 1986Assignee: AT&T Technologies, Inc.Inventors: Parry A.

Patent number: 4574732Abstract: Disclosed is an overvarnish unit for applying varnish to a web of printed material as a protective overlay. The overvarnish unit includes a varnish fountain for receiving paste varnish, a form roller, and a plurality of rollers intermediate the fountain and form roller. The form roller engages an impression cylinder roller forming part of a printing assembly. The varnish is transferred from the fountain to the form roller by the intermediate rollers which also mill the varnish as it is being transferred to reduce its viscosity. The form roller is driven at a peripheral speed greater than the linear speed of the web over the impression cylinder roller. This form roller overspeed provides a smearing action in applying the varnish to the web rather than a one to one or line by line printing action thus achieving control over the thickness of the applied varnish and the appearance of the final product.Type: GrantFiled: May 29, 1984Date of Patent: March 11, 1986Assignee: Feco Engineered Systems, Inc.Inventors: William G. Verwey, John C. Hovekamp

Patent number: 4413587Abstract: An apparatus to apply uniform amounts of adhesive to containers at a high rate of speed. Containers are selected at a variable interval. The containers are positioned against dual spiral timing screws (one timing screw above the other). Turning the timing screws a constant (but adjustable) number of degrees with respect to each other while they rotate at the same speed will either advance a container in a level position or they may be advanced while tilted, forward or backward depending upon the relative position of the upper and lower timing screw. While the container is advancing, it is also being turned so that the upper surfaces of the container may be positioned against a rotating cylinder to which a layer of adhesive is continuously applied. In this manner adhesive may be applied around the entire circumference of a container on the top, inside edge, outside edge or both edges.Type: GrantFiled: September 14, 1981Date of Patent: November 8, 1983Assignee: Tools & Machinery Builders, Inc.Inventor: Ronald Cook
