Patent number: 6651507Abstract: Various embodiments are disclosed of dampening apparatus for a pressure gauge in which a short length of sleeve, ferrule, hub or thimble encircles a pointer shaft in a close but loose fit relation defining a clearances packed with a high viscosity dampening agent such that it serves to decelerate and cushion any sudden shock or pulsation force that would otherwise be transmitted from the pointer shaft to a pointer registering values of pressure of fluid pressure being monitored.Type: GrantFiled: June 7, 2000Date of Patent: November 25, 2003Assignee: Dresser, Inc.Inventors: John C. Hamma, Walter J. Ferguson, Jeffrey T. Blake, Michael J. Maloney, Louis A. Rosen

Patent number: 5675959Abstract: Apparatus for opening an envelope having a front panel, a back panel and a closing flap. The apparatus includes: a device for supporting the envelope in a substantially horizontal plane wherein the back panel is situated above the front panel; a device for holding the closing flap below the back panel; an opening horn for separating the back panel from the front panel, the opening horn being pivotable in a vertical plane; and a device for causing the horn to initially contact the closing flap and to pivot the horn into the envelope between the front and back panels, and to raise the horn inside the envelope, whereby the front and back panels are separated.Type: GrantFiled: January 18, 1996Date of Patent: October 14, 1997Assignee: Pitney Bowes Inc.Inventors: John C. Hamma, Martyn R. House, David W. Hubbard, John R. Nobile

Patent number: 5507380Abstract: By providing a package processing system with pulsed or intermittently applied package retardation or separation forces, a highly effective package handling system is attained which is able to process all packages without tearing, ripping, or damaging any surfaces or surface coverings. In its preferred construction, the packages are advanced in one direction and contact one or more rollers rotationally driven to the opposed direction in order to retard and separate stacked packages into a single level array. In addition, each roller is continuously raised and lowered out of and into engagement with the packages passing therebelow. By providing this pulsed or intermittent force, the packages are separated as desired, while also preventing damage to any package surface.Type: GrantFiled: September 20, 1994Date of Patent: April 16, 1996Inventor: John C. Hamma

Patent number: 5508818Abstract: A system for transporting mixed documents having a loading conveyor for transporting documents to a document prefeeder. The document prefeeder transports documents from the loading conveyor on an angled conveyor to a stack feeder that accumulates a shallow stack of documents. A single document feed removes single documents from a shallow stack on the stack feeder and transports the single documents to a main conveyor. A camera on the main conveyor reads each document such as mail, and prints information concerning the document, such as a bar code, on each document. The documents are moved by the main conveyor to an output conveyor for sorting and accumulation.Type: GrantFiled: September 23, 1994Date of Patent: April 16, 1996Assignee: Scan-Code, Inc.Inventor: John C. Hamma

Patent number: 5457636Abstract: A postal finishing kiosk in which a user is provided with a mail piece, such as a postcard. The user supplies the name and address to which the mail piece is to be sent and the kiosk dispenses a finished mail piece to the user with the address printer thereon. A feature of the kiosk is that it stores the mail piece forms on a roll, but delivers a linear mail piece to the user. In an alternative to the invention, the kiosk dispenses a ticket to the user that can be used in activities of the environment in which the kiosk is found.Type: GrantFiled: July 29, 1993Date of Patent: October 10, 1995Assignee: Pitney Bowes Inc.Inventors: Ronald P. Sansone, Michael D. O'Hare, Steven M. Kaye, John C. Hamma, John T. Balga, Jr., Fran E. Blackman, David W. Hubbard, Kevin D. Hunter, Wendy F. Jai, Scott Korowotny, Jeffrey D. Pierce

Patent number: 4466608Abstract: An apparatus is disclosed for receiving sheets from the discharge portion of an electrostatic copy machine, which apparatus receives, stacks and collates the sheets as desired. The apparatus can be electrically independent of the copier and is attached thereto by simple hanger and bracket arrangements. The apparatus includes a plurality of trays which are moved past the discharge opening of the copier, and which are controlled and arranged, selectively to receive (1) a plurality of sheets in each tray; (2) a single copy of each sheet in each of several trays; or (3) a number of identical sheets in one tray and a differing number of other sheets in successive trays. The apparatus can collect, collate, and sort the sheets while the trays are moving in one direction past the copier discharge opening, as well as when the trays are moving past it in the other direction.Type: GrantFiled: February 1, 1982Date of Patent: August 21, 1984Assignee: Gradco Systems, Inc.Inventors: R. Clark DuBois, John C. Hamma

Patent number: 4397461Abstract: A sorting machine has bins which are shifted sequentially past a sheet entry location between positions at opposite sides of the sheet entry location, to provide a relatively wide sheet receiving space between adjacent bins at the entry location. The bins have their outer ends pivotally mounted in a frame structure spaced from the sheet entry location, so that the bins slope forwardly. Shifting of the bins is accomplished by a reversible motor driven rotor located at one side of the bins and having recesses to receive trunnions at one side of the bins on each one-half revolution to shift a bin in one direction or the other. The other side of the bin group is unobstructed.Type: GrantFiled: October 21, 1981Date of Patent: August 9, 1983Assignee: Gradco/Dendoki, Inc.Inventors: R. Clark DuBois, John C. Hamma

Patent number: 4332377Abstract: A sorting machine is provided for attachment to a copying machine to receive successive sheets from an outlet from the copying machine. The sorting machine has plural trays mounted to move progressively past the sheet outlet in opposite directions, the trays being relatively close together when positioned at either side of the outlet, but adjacent trays being widely spaced to accommodate the incoming sheets from the outlet. The trays are fed past and spaced at the outlet by driven members at opposite sides of the tray which engage and shift stacked trays in succession. The driver members are notched discs functioning as a linear Geneva movement. The remote ends of the trays are freely supported one on the other for relative longitudinal and pivotal movement. In certain forms, the remote tray ends are mounted one on the other by end pieces which have wedge surfaces causing the remote ends to be spaced apart responsive to longitudinal movement of the trays.Type: GrantFiled: January 27, 1981Date of Patent: June 1, 1982Assignee: Gradco/Dendoki, Inc.Inventors: R. Clark DuBois, John C. Hamma

Patent number: 4186837Abstract: A conveyor moves a series of cartridges containing undeveloped film and sender-identified mailers in correlated side-by-side relation from a loading station past a cartridge sensing station, a dual labeling station, and a plurality of discharge stations. Information sensed from each cartridge is stored in a memory and later controls the off-loading of the correlated cartridges and mailers at an appropriate one of the discharge stations from which the cartridges go their separate ways for film processing. Prior to off-loading, the side-by-side cartridge and mailer receive separate labels preprinted with correlating indicia enabling the developed film and the mailer to be correctly reunited for return to the sender.Type: GrantFiled: December 27, 1978Date of Patent: February 5, 1980Assignee: Mystic Color Lab, Inc.Inventors: Stanley Popiel, R. Clark DuBois, Jay L. Carley, John C. Hamma
