Patent number: 4792426Abstract: A process for precisely controlling the thickness of a heat-softenable sheet material (52) comprising heating the material to bring it to a softened condition, compressing the material while in the softened condition to the desired thickness or somewhat less and then cooling the material to a temperature below its softening point so that it sets while precisely maintained at the desired thickness. The material is cooled by passing it between substantially parallel cooling plate (32,34) rigidly spaced with a separation equal to the desired thickness of the material.Type: GrantFiled: November 6, 1987Date of Patent: December 20, 1988Assignee: USM CorporationInventors: Anthony T.

Patent number: 4775280Abstract: An apparatus for automatically supplying electrical components from a series of tubular holders held in a cassette to the magazine of an electrical component assembly machine. The apparatus is carried on a channel base movable from a position with the cassette over the workstation to a position with the cassette remote from the workstation. The components are released from the cassette down a chute to the workstation, the chute having a stop member releasable when the channel base is moved to prevent the release of components from the chute. A component presence reader is located in the chute and is disposed at an acute angle to the chute vertical axis to obtain an accurate reading of the presence or absence of a component in the chute.Type: GrantFiled: July 23, 1986Date of Patent: October 4, 1988Assignee: USM CorporationInventor: John S. Kelley

Patent number: 4756073Abstract: It is convenient to supply electrical or electronic components for placement on tapes; however it has proved difficult to satisfactorily handle tapes for carrying large components. Use of wide tapes to feed larger components is facilitated by using a drive belt (48) to rotate at a sprocket wheel (44) to feed the tape (38,40), a drive wheel (52) to move the belt, and drive means conveniently a ratchet wheel to cause the drive wheel (52) to rotate through a predetermined angle to feed the tape a distance equal to the spacing between the components on the tape. Wide tape can conveniently be disposed of after unloading by using means (88,90) for severing the tape (38) immediately downstream of an unloading position, and means for collecting the severed tape preferably comprising a duct (84) through which a current of air flows to carry the severed tape to a remote receptacle (85).Type: GrantFiled: May 22, 1986Date of Patent: July 12, 1988Assignee: USM CorporationInventor: Victor T. Hawkswell

Patent number: 4747294Abstract: A device for automatically presenting mandrel rivets to the nosepiece of a rivet installation tool, which receives rivets from a supply in a slidably mounted transfer arm while the arm is in a retracted position, and axially and radially moves the arm relative to the tool axis to a position of alignment with receiving jaws within the tool. The rivet is then propelled into the tool's nosepiece from the transfer arm by an air blast. The presentation device may be separately mounted within a rivet installation machine, or may be mounted to the tool body in a hand-held configuration. A first version provides successive, separately actuated axial and angular movements of the transfer arm, while a second version provides simultaneous axial and angular movement of the arm. The rivet is held within the transfer arm by a vacuum, which vacuum may be rapidly changed to a positive pressure on command to propel the rivet from the arm into the tool.Type: GrantFiled: March 19, 1987Date of Patent: May 31, 1988Assignee: USM CorporationInventors: Sidney D. Schwartz, Thomas P. Shamaly, Donald Viscio, Raymond H. Varian
