Patent number: 8191584Abstract: On cold filling of pressure containers the filling gas is cooled before introduction into the pressure container to be filled. On completion of the filling process the pressure container is sealed in a pressure-tight manner. As the gas warms up the pressure in the pressure container rises rapidly. According to the invention, the pressure container is cooled before the introduction of the filling gas. The filling gas cools rapidly by means of heat transfer to the pressure container, whereby the filling capacity of the pressure container is considerably increased. Said method is particularly suitable for the filling of small tanks, in particular, for gas-driven vehicles and fuel-cell systems.Type: GrantFiled: February 18, 2002Date of Patent: June 5, 2012Assignee: L'Air Liquide Societe Anonyme pour l'Etude et l'Exploitation des Procedes Georges ClaudeInventors: Martin Kesten, Friedel Michel

Patent number: 4613321Abstract: A tandem arrangement of diecutting rolls severs scrap from a traveling web in two steps, each of which steps effects cutting entirely through the web, but at different peripheral locations. The partially cut scrap is carried with the remainder of the web from the first roll to the second, and any severed piece that lodges within the cutting element of the second roll is removed by the action of a mechanical scraper, which passes therethrough.Type: GrantFiled: September 6, 1985Date of Patent: September 23, 1986Assignee: Preston Engravers, Inc.Inventors: Martin Kesten, Leroy H. Carlson, Jr., Gary L. Kwader

Patent number: 4599926Abstract: A die-cutting roll is constructed to cut holes in traveling web materials, and for clearing and discharging the fragments, in a highly effective manner. A multiplicity of air vent ports communicate with the channel through which the scrap moves to an internal axial passage of the roll, and supplement the effect of vacuum applied to one end thereof. Desirably, a disuniting effect is produced upon compacted formations strands of the removed material, by creating turbulence within the passage and/or by mechanical impact thereupon.Type: GrantFiled: July 16, 1984Date of Patent: July 15, 1986Assignee: Preston Engravers, Inc.Inventors: Leroy H. Carlson, Jr., Martin Kesten

Patent number: 4542671Abstract: Die-cutting roll assemblies are provided which utilize a shaftless die roll. In certain embodiments, stability in the press is provided by an assist adaptor which has flanged bearings that cooperatively support the die roll laterally and transversely. In other embodiments, the roll is supported in a frame that has removable centers, which permit the use of rolls of various lengths in the assembly.Type: GrantFiled: May 21, 1984Date of Patent: September 24, 1985Assignee: Preston Engravers, Inc.Inventor: Martin Kesten

Patent number: 4507996Abstract: A device for transferring and monitoring the load applied to a die cutting roll in a press has a pressure indicator for registering applied force. By utilizing an elongated member having such a pressure indicator adjacent each of its opposite ends, or by utilizing two such devices with an assist roller mounted therebetween, the force applied to the opposite ends of the underlying die roll can readily be determined, and adjusted if necessary. The load-bearing members of the device preferably comprise a diaphragm mounted on the body in sealing relationship over a recess, to which the pressure indicator is operatively connected.Type: GrantFiled: November 15, 1982Date of Patent: April 2, 1985Assignee: Preston Engravers, Inc.Inventor: Martin Kesten

Patent number: 4455903Abstract: An anvil roll, for use with a rotary cutting or creasing die, has an expandable shell by which the clearance therebetween can readily be varied. The position of the shell surface is controlled by hydraulic pressure, the magnitude of which is determined by the location of an adjustable piston within a suitable cylindrical section of the internal hydraulic system.Type: GrantFiled: November 15, 1982Date of Patent: June 26, 1984Assignee: Preston Engravers, Inc.Inventor: Martin Kesten

Patent number: 4191077Abstract: A bearing-block body member in which a die-cutting roll is journaled includes an adjusting cap seated in it through which a bore extends axially of the roll. An axial chamber is provided in the roll, and a stationary air manifold extends into the chamber, permitting relative rotation between the roll and the manifold. An air tube having an axial portion and a transverse portion has its axial portion extending through the bore in the adjusting cap to couple with the manifold so as to hold it in rotational position but permit axial withdrawal. Fluid communication is provided between the air tube and the manifold, and corresponding ports in the manifold and apertures in the die register periodically to permit air to flow from the air tube through the manifold, the ports, and the apertures to the outer surface of the roll. As a result of this arrangement, air can be supplied transversely of the axis of the roll, but ready removal of the roll and the manifold is afforded.Type: GrantFiled: December 26, 1978Date of Patent: March 4, 1980Assignee: Preston Engravers, Inc.Inventors: Richard L. Edwards, Martin Kesten

Patent number: 4159655Abstract: An adjustable eccentric assembly is mounted on a rotatable shaft and includes a first or drive collar having an arbor extending along the shaft and a second or guide collar mounted at the end of the arbor spaced from the drive collar. The drive collars have respective guide surfaces extending parallel to the axis of rotation of the shaft and a guide track is formed in the guide collar guide surface extending perpendicularly of the axis of rotation. A hub member is supported between the guide and drive collars and engages the guide track. Adjusting means serve to shift the hub member radially relative to the rotatable shaft to adjust the eccentricity of its rotation about the shaft. A throw member having a projecting link may be rotatably mounted on the hub member so that the eccentric rotation of the hub member imparts a reciprocating motion to the throw link.Type: GrantFiled: December 29, 1977Date of Patent: July 3, 1979Assignee: Preston Engravers, Inc.Inventors: Arthur R. Johnson, deceased, by Paul A. Hudon, administrator, Martin Kesten

Patent number: 4143597Abstract: A plurality of circumferentially extending mounting recesses are formed in a cylinder assembly and arcuate saddle members having marking means, such as print type, on their outside surface are mounted in the recesses. Each saddle member has a locking recess formed in its inside surface with a pair of spaced apart, flexible locking wires extending therethrough. Mounting studs having a mounting head with a relatively narrow neck portion are affixed to the cylinder within the mounting recesses. The saddle members may be mounted within the mounting recesses by snap-on engagement of the mounting head with the locking wires, and readily removed by snap-off disengagement of the head with the wires. The saddle members may thus be readily replaced and interchanged by means of the snap-on, snap-off mounting and demounting.Type: GrantFiled: April 27, 1977Date of Patent: March 13, 1979Assignee: Preston Engravers, Inc.Inventors: Martin Kesten, Frank W.
