Patent number: 10658156Abstract: A system and method for generating a plurality of scan profiles based on a desired implant pattern and the uniformity of the spot beam is disclosed. The system scans the spot beam and records the number of ions as a function of position. This is referred to as the linear uniformity array. The desired implant pattern and the linear uniformity array are then combined to generate a composite pattern array. This array contemplates the non-uniformity of the scanned beam and allows the system to create scan profiles that compensate for this. The software may be executed on the controller disposed in the implantation system, or may be executed on a different computing device.Type: GrantFiled: February 1, 2019Date of Patent: May 19, 2020Assignee: Applied Materials, Inc.Inventors: Stanislav S. Todorov, Jeffrey Morse, John Sawyer

Patent number: 8668831Abstract: The present invention provides for a permeable reactive barrier and an effective method of removing contaminants from water using adsorbent powders, such as zero valent iron particles, adhered throughout a reticulated foam structure. This structure provides improved mass transfer, higher reaction rates and reduced residence times. The barrier includes a reticulated foam substrate with high permeability, an adherent coating and a reactive adsorbent arranged in a reticulated foam structure. The substrate can be selected from various materials including polyurethane and polyester. The adherent may be selected from a wide range of materials including polyurethanes, acrylics, silicones, siliconized acrylics, latex emulsions, and other inherently tacky materials that cure to a water resistant coating. The reactive adsorbent can be selected from various adsorbents including a powdered zero-valent iron (ZVI).Type: GrantFiled: April 19, 2010Date of Patent: March 11, 2014Assignee: Liberty Hydro, Inc.Inventors: John Sawyer, Geoffrey Papelier, Marty L. Weirick

Publication number: 20120018384Abstract: The present invention provides a method of removing mercury from water. The method includes depositing selenium or a reactive selenium compound on a support structure, such as reticulated foam. The support structure is then placed in contact with mercury laden water whereby allowing the selenium and the mercury in the water to react. The selenium deposited support structure retains the mercury thereby removing the mercury from the mercury laden water.Type: ApplicationFiled: January 31, 2011Publication date: January 26, 2012Inventor: John Sawyer

Patent number: 7153112Abstract: A compressor and a method for compressing fluid according to which a liner is disposed on the inner wall of a housing defining a bore. At least one slot and at least one discharge port are provided in the liner. A rotor is rotated in the housing with its outer surface in a closely spaced relation to the inner wall of the liner, and an additional rotor extends through the slot in the liner and intermeshes with the first rotor to compress fluid introduced between the rotors before it is discharged through the port.Type: GrantFiled: December 9, 2003Date of Patent: December 26, 2006Assignee: Dresser-Rand CompanyInventors: Philip A. Zarnoch, Michael A. Cary, John A. Sawyer

Publication number: 20060206922Abstract: The present invention is directed to a system and a method to facilitate remote secure access from a remote client to a non-public web server having a web browser. The process includes the steps of establishing a list of all authorized remote client users for a non-public host web server. The remote client web servers are in communication with the non-public web server. Authorized remote client user access is validated and data traffic is permitted between the remote client user and the non-public web server. Software permits remote configuration and utilization of application software which is in communication with the non-public web server.Type: ApplicationFiled: March 8, 2005Publication date: September 14, 2006Applicant: SECUREDATAINNOVATIONS AGInventors: R. Johnson, John Sawyer

Patent number: 5435704Abstract: Volume ratio and capacity are controlled by slides which are rail guided. The slides are pressure-balanced, axillay and radially. The volume ratio slide has a piston balancing arrangement. The capacity slide has suction pressure acting equally on all sides thereof, consequently it requires no piston balancing.Type: GrantFiled: October 3, 1994Date of Patent: July 25, 1995Assignee: Dresser-Rand CompanyInventor: John A. Sawyer

Patent number: 5078580Abstract: The compressor, of the reciprocating-piston type is actuated by a camshaft confined in a small, compact frame. Cams translate cross-heads which are slidably guided within the frame, and which are threadedly coupled to depending stubs of the pistons. A bolted-on head plate confines valving components atop cylinders set within the frame, and the head plate has passageways formed internally to conduct the gas to and from successive stages of compression.Type: GrantFiled: March 29, 1991Date of Patent: January 7, 1992Assignee: Dresser-Rand CompanyInventors: Bernard F. Miller, John A. Sawyer

Patent number: 4964332Abstract: The pin assembly comprises a piston or crosshead connecting pin which has a throughgoing, axial hole formed therein which is tapped at one end to receive a headed fastener. Radial bores are formed in the connecting pin which bores open onto the axial hole and also onto the outer surface of the connecting pin. Locking pins are slidably disposed in the radial bores so that, as a headed fastener is threaded into the tapped end of the axial hole, the head of the fastener forces the locking pins to protrude from the radial bores and engage an annular groove, provided therefor, in the piston or crosshead.Type: GrantFiled: September 15, 1989Date of Patent: October 23, 1990Assignee: Dresser-Rand CompanyInventor: John A. Sawyer

Patent number: 4957416Abstract: The Compressor comprises three stages of compression, having three cylinders, each of the latter having a piston reciprocable therein. Two of the pistons are in-line along a common axis, and the cylinders therefor are in confronting relationship. The third cylinder lies along an axis which traverses the two-piston axis. All three pistons are reciprocated by two connecting rods, in that the in-line pistons are joined by tie rods. Both connecting rods are coupled to the single crank of a crankshaft which is journalled in a crankcase, and all three cylinders are removably bolted to the crankcase.Type: GrantFiled: September 11, 1989Date of Patent: September 18, 1990Assignee: Dresser-Rand CompanyInventors: Bernard F. Miller, John A. Sawyer

Patent number: 4890542Abstract: The seal, for use especially in non-lubricated, high-pressure, as compressors, in a one-piece, continuous sleeve which envelopes a reciprocable piston for sealing against the piston, or against the cylinder in which the piston translates. One end of the sleeve effects the sealing engagement, and the other end is spring-loaded to maintain the engagement. During operation of the compressor, or the like, it is the high-pressure gas which urges the seal into sealing engagement.Type: GrantFiled: September 6, 1988Date of Patent: January 2, 1990Assignee: Ingersoll-Rand CompanyInventors: Bernard F. Miller, John A. Sawyer, Wayne F. Wehber
