Patent number: 6004253Abstract: A machine and method for converting a web having an indefinite length which includes a plurality of converting stations circumferentially spaced about an process drum. At least one of the converting stations includes a helical follower gear operatively meshing with a helical drive gear attached to the process drum. Movement of the follower gear along its axial direction provides for the relative rotational registration of a tool on the registrable converting station relative to the web.Type: GrantFiled: October 14, 1997Date of Patent: December 21, 1999Assignee: 3M Innovative Properties CompanyInventors: John E. Riedel, Clarence A. Niven, Jr.

Patent number: 5133355Abstract: A biomedical electrode is disclosed which generally comprises an insulator construction and a conductor member. The conductor member is preferably a thin flat, flexible member having a pad portion and a tab portion. The insulator construction is arranged such that the conductor member pad portion is positioned on one side of the insulator construction and the tab portion is generally positioned on an opposite side. Three general embodiments are disclosed which achieve this: a first comprising two overlapping sections of insulator material, with the tab portion of the conductor member extending outwardly from therebetween; a second in which two sections of insulator construction material are oriented in a substantially coplanar relationship to define a seam therebetween, through which a portion of the conductor member extends; and, a third in which the insulator construction includes a single sheet of material having a slot therein, through which a portion of the conductor member extends.Type: GrantFiled: November 5, 1991Date of Patent: July 28, 1992Assignee: Minnesota Mining and Manufacturing CompanyInventors: Jerome E. Strand, Lawrence W. Craighead, Clarence A. Niven

Patent number: 4798642Abstract: A biomedical electrode comprised of an electrical terminal member, an ionically conductive layer, a retainer sheet, a medical tape, first and second release liners, and a protective sheet is provided. The base of the electrical terminal member is disposed between the retainer sheet and the ionically conductive layer so that the retainer sheet prevents dislodging of the terminal upon connection and disconnection of a lead-wire. Also disclosed is an economical high speed method of manufacturing electrodes.Type: GrantFiled: November 17, 1987Date of Patent: January 17, 1989Assignee: Minnesota Mining and Manufacturing CompanyInventors: Lawrence W. Craighead, Clarence A. Niven
