Patent number: 5503702Abstract: A labeling assembly for applying labels carried on a substrate to a sequential series of moving documents is provided. The assembly transports the document in a generally vertical end on end orientation down a conveying path and peels the label from the substrate to position the peeled label in a generally vertical orientation. The labeling assembly also includes a paddle having a front surface with vacuum ports for attaching and releasably retaining the peeled label on the front surface. An actuating mechanism pivots the paddle to force an end of the retained label into contact with the document. Upon contact, the downstream end of the retained label adheres to the document and the label is pulled off the paddle. As the label is pulled off the paddle the contact between the end of the paddle presses the label against the document.Type: GrantFiled: March 1, 1994Date of Patent: April 2, 1996Assignee: Bell & Howell CompanyInventors: David D.

Patent number: 5494276Abstract: Apparatus for shingling a plurality of documents disposed in stacked relation so that the stack extends successively from a first end to a second end, and has at least one boundary defined by substantially coplanar marginal edges of the documents. The stack of documents is conveyed along a predetermined path during which one or more rotatable shingling members engage the coplanar marginal edges of the documents and impart velocity components of progressively increasing magnitude to the marginal edges in a manner to effect movement of the documents into a shingled array. In the preferred embodiments, the rotatable shingling member has a conical shingling surface traversed by the documents in tangential relation so that the velocity components imparted to the marginal edges of the documents lie in the planes of the documents and move them laterally in shingled relation to each other.Type: GrantFiled: January 3, 1994Date of Patent: February 27, 1996Assignee: Bell & Howell CompanyInventors: Thomas Faber, Kenneth L.

Patent number: 5475550Abstract: A magnetoresistive transducer design for cross-talk supression and increased Neel temperature is disclosed. The transducer is formed by fabricating on a suitable substrate an antiferromagnetic material layer above and below the permalloy layer. The additional antiferromagnetic layer between the substrate and the permalloy increases the exchange coupling biasing of the magnetoresistive transducer thereby providing increased cross-talk supression and greater longitudinal bias. The location of the additional antiferromagnetic layer beneath the permalloy also increases the Neel temperature of the transducer. A permanent magnetic material can also be substituted for the antiferromagnetic material with the result that the longitudinal bias is increased by coupling to the upper and lower surfaces of the permalloy layer thereby doubling the effect.Type: GrantFiled: May 6, 1994Date of Patent: December 12, 1995Assignee: Seagate Technology, Inc.Inventor: Peter K.
