Patent number: 6103013Abstract: This disclosure relates to a method and apparatus for reliably inserting a tab or other marker into a bobbin of material which is undergoing a converting or other processing step. A spindle having a retention device such as a vacuum or magnetic zone which holds the tab or marker with an adhesive side facing outwardly is described. In operation, the spindle is moved into engagement with the surface of the web and the tab or marker is applied precisely and with considerable force. Reduction in unplaced tabs, paper jams, and tearing may be accomplished by the reduction of user error.Type: GrantFiled: April 9, 1998Date of Patent: August 15, 2000Assignee: Philip Morris IncorporatedInventors: William H.

Patent number: 5944278Abstract: A method and apparatus for reducing, capturing and disposing of the waste start up web of paper in high-speed manufacturing procedures which involve a converting step, e.g. laser perforation or the like. Specifically, the converting apparatus and the web speed are carefully and precisely controlled by a programmable logic controller to result in a rapid production of converted web with a minimum of waste. The apparatus and method are tuned by sampling the waste and web for conversion quality, and using that information to adjust the converting apparatus and bias that adjustment for maximum reduction in waste.Type: GrantFiled: October 16, 1997Date of Patent: August 31, 1999Assignee: Philip Morris IncorporatedInventors: William H.

Patent number: 5750964Abstract: A smoking system is provided in which a replaceable cigarette containing tobacco flavor material is electrically heated by a set of electrical heater elements contained within a lighter to evolve tobacco flavors or other components in vapor or aerosol form for delivery to a smoker. The cigarette and lighter are adapted to provide air flow patterns through the smoking system such that air flows transversely into the cigarette. Such patterns improve aerosol and flavor delivery to the smoker and reduce the condensation of residual heater-region vapor/aerosol in the smoking system.Type: GrantFiled: January 29, 1997Date of Patent: May 12, 1998Assignee: Philip Morris IncorporatedInventors: Mary E.

Patent number: 5688161Abstract: A sharpening and cleaning apparatus for sharpening scalloped-edged blades in a carton slitting machine includes at least two rotating cylindrical hones mounted on a pneumatically controlled actuator, and a pair of blade cleaning brushes mounted on a separate actuator. A sharpening operation is initiated by a machine operator as needed to maintain blade sharpness, and is performed automatically by the apparatus controls. The hone actuator positions the rotating hones in contact with opposing sides of a cutting edge of the slitting blade as the blade moves past the hones at reduced speed. A first hone is rotated in a direction opposite to the direction of the blade and a second hone is rotated in the same direction of the blade. During sharpening, the hones execute several reciprocating axial movements to stroke the blade. Prior to the operation of the hones the actuator positions the brushes in contact with the blade and causes the brushes to rotate to remove debris from the blade.Type: GrantFiled: July 24, 1995Date of Patent: November 18, 1997Assignee: Philip Morris IncorporatedInventors: J.

Patent number: 5600478Abstract: The disclosure relates to a laser marking system, using a displaceable mirror to cause the path of the laser beam to scan in one direction. The mirror is conveniently controlled by at least one flexure hinge driven by a piezo electric device, an electro-strictive device or a magneto-strictive device. In one disclosed embodiment two mirrors (15,16,) are provided, each mirror (15 or 16,) having a flexure hinge device (18,19) individual thereto, and the displacements applied to the flexure hinge devices (18,19,), via respective driving devices (20,21,), cause the mirrors (15,16,) to scan the path of the laser beam (13) in a series of steps in one direction of scan. A computer (11), arranged to drive the flexure hinge driving devices (20,21,), also controls the firing of the laser (12) in accordance with a predetermined program.Type: GrantFiled: July 1, 1994Date of Patent: February 4, 1997Assignee: Imaje SAInventor: William H.

Patent number: 5530324Abstract: The invention relates to a resonance reducing arrangement for a device displaceable between two positions.In one described embodiment the device (14) is displaced against the resilience of a spring (11) by causing an electrical device (15) to accelerate the device (14) towards its second position, terminating the force accelerating the device (14) to allow the device to continue to displace towards the second position and then reactivating the electrical device (15) to cause the electrical device (15) to expand to that position at which it holds the device (14) in its second position.Type: GrantFiled: May 27, 1994Date of Patent: June 25, 1996Assignee: Technology Systems LimitedInventors: Edwin D. Gaskell, William H. Stevens

Patent number: 4025560Abstract: A process for the exchange of hydrogen isotopes between streams of gaseous hydrogen and liquid water, wherein the streams are brought into contact with one another and a catalyst assembly at a temperature in the range 0.degree.-300.degree. C. The catalyst is an inherently hydrophobic material such as polytetrafluoroethylene, polyethylene, polystyrene, polymethacrylate, polypropylene or carbon black carrying a catalytically active metal, for example, platinum, rhodium and nickel. The inherently hydrophobic support allows the catalytically active metal to catalyze the hydrogen isotope exchange reaction between hydrogen gas and water vapor in the presence of liquid water while retarding loss of activity of the catalytically active metal by contact of the metal catalyst with liquid water.Type: GrantFiled: December 12, 1973Date of Patent: May 24, 1977Assignee: Atomic Energy of Canada LimitedInventors: John H. Rolston, William H. Stevens, James Denhartog, John P. Butler
