Patent number: 10393021Abstract: An air-inlet duct includes an outer wall, an inner wall, and a splitter. The splitter cooperates with the outer wall and the inner wall to establish a particle separator which separates particles entrained in an inlet flow moving through the air-inlet duct to provide a clean flow of air to a compressor section of a gas turbine engine.Type: GrantFiled: June 29, 2017Date of Patent: August 27, 2019Assignee: Rolls-Royce North American Technologies Inc.Inventors: Crawford F. Smith, III, Victor Oechsle, Philip Snyder

Publication number: 20120179904Abstract: A host computer cloud has a processor and supports a virtual machine. An agent under control of a user is in communication with the cloud over a network. A key management server is in communication with the cloud over a network. The cloud stores the virtual machine in the form of a virtual encrypted disk on a non-volatile storage medium. When commanded by the agent, the cloud requests a disk-wrapping key from the key management server and decrypts the encrypted disk using the disk-wrapping key.Type: ApplicationFiled: November 14, 2011Publication date: July 12, 2012Applicant: SafeNet, Inc.Inventors: Chris Dunn, Russell Dietz, Philip Snyder, Alan H. Frindell

Publication number: 20070186534Abstract: A particle separator for use in connection with a gas turbine engine is disclosed. The particle separator extends circumferentially less than 360 degrees between a first end and a second end. In one embodiment, an inner scavenge conduit is spaced radially inward from an outer scavenge conduit. An inlet can be located between the outer scavenge conduit and the inner scavenge conduit and adapted to receive airflow. A plurality of separated airflow paths can be located between the inner and outer scavenge conduits. The outer scavenge conduit and the inner scavenge conduit can be adapted to receive particles separated from the inlet airflow as the inlet airflow passes along the curved separating portion.Type: ApplicationFiled: December 4, 2006Publication date: August 16, 2007Inventor: Philip Snyder

Publication number: 20070157625Abstract: A constant volume combustor device includes detonative combustion. In one form the wave rotor of the constant volume combustor is supported by magnetic bearings.Type: ApplicationFiled: October 24, 2006Publication date: July 12, 2007Inventors: Philip Snyder, Calvin Emmerson

Publication number: 20070095033Abstract: A particle separator for separating particles and/or materials entrained in a flow of air is disclosed. The particle separator includes an annular inlet defined by an outer shroud and an inner shroud. An upper forward flow divider and a lower forward flow divider is disposed within the annular inlet. A first and second radially spaced annular flow divider is adapted for directing said flow of air into at least a first, second, third and fourth flow passageway. At least four curved flow splitters are utilized for separating particles and/or materials entrained in the flow of air as it passes through the first, second, third and fourth flow passageways.Type: ApplicationFiled: December 1, 2006Publication date: May 3, 2007Inventor: Philip Snyder

Patent number: 6666100Abstract: A manual sample injector includes a syringe holder, a plunger driver, and an interface. An interface-control lever attached to the interface can assume “extraction”, “injection”, and “safety” orientations. In its safety orientation, the interface-control lever maintains a syringe needle in a retracted position for safety. Mounting the sample injector on a sample vial forces the interface-control lever to its extraction orientation, which allows the syringe needle to extend into the sample vial for sample extraction. The extent of the needle into the sample vial can be adjusted for precise extraction of sample from non-uniform vial contents. Mounting the injector on an injection port forces the interface-control lever to its injection orientation so that the syringe needle can be extended to an appropriate depth for sample injection.Type: GrantFiled: December 16, 2002Date of Patent: December 23, 2003Assignee: Merlin Instrument CompanyInventor: Philip A. Snyder

Patent number: 6257076Abstract: A manual sample injector for a gas chromatograph comprises a syringe holder, a plunger driver including a volume-adjust assembly, an injection port interface, a release lever, and a force-calibration spring. The holder, driver, and interface collectively include guide rod and respective apertures so that the driver and interface can slide vertically relative to the holder. Pre-injection steps provide that the desired volume of sample is ready for injection. Injection steps include: mounting the injector on an injection port by sliding the port interface over a septum cap of the injection port, manually pushing the plunger driver, and thus the syringe holder, down against the resistance of the force-calibration spring until an actuator element of the port interface contacts the cocked release lever, increasing the downward force on the plunger driver so that the release lever is forced to a release position.Type: GrantFiled: January 26, 1999Date of Patent: July 10, 2001Assignee: Merlin Instrument CompanyInventors: Philip A. Snyder, James Steven Fullemann

Patent number: 5853591Abstract: An aquarium filter system having a rotatably mounted filter body. The filter body is structured such that when mounted with a portion of the filter body submerged in moving water, rotational movement is imparted to the filter body by the moving water. As a result of the rotational movement, at least a portion of the filter body is alternately exposed to the water and the atmosphere. This fosters the growth of aerobic bacteria on the surface of the filter body. The aerobic bacteria reduces the level of toxins within the aquarium water.Type: GrantFiled: October 3, 1994Date of Patent: December 29, 1998Assignee: Aquaria, Inc.Inventors: Wilfred Philip Snyder, Charles Otto Fuerst, Joseph Scott Bussing

Patent number: 4331262Abstract: A fluid dispenser pumps fluid in increments. The dispenser includes a computer which, on command, determines the volume of fluid dispensed per increment, the determined value constituting a calibration value which is stored in the memory of the computer. A controller which may include the computer as a component provides for dispensing a selected number of doses, each of a selected volume. The controller can also specify a time interval between the delivery of successive doses. The dispenser is particularly useful in combination with apparatus for charging petri dishes with agar.Type: GrantFiled: September 5, 1979Date of Patent: May 25, 1982Assignee: New Brunswick Scientific Co., Inc.Inventors: Philip Snyder, David Freedman

Patent number: 4170861Abstract: A method and apparatus for filling petri dishes include the features of situating a stack of empty petri dishes at a dish-drop station where the stack rests with the lowermost petri dish of the stack on a stationary support. A moving structure engages this lowermost petri dish and moves it beyond the stationary support to a filling station, and during this movement of this lowermost petri dish to the filling station a lower dish member of the petri dish drops down from an upper lid member thereof and remains spaced beneath the upper lid member while being supported by a movable support which carries the lower dish member to the filling station. At the filling station a nozzle of a pump becomes situated in the space between the upper lid member and the lower dish member of the petri dish and fills a given quantity of agar into the lower dish member, whereupon this latter member and the upper lid member spaced thereover are moved to an elevating station.Type: GrantFiled: April 7, 1978Date of Patent: October 16, 1979Assignee: New Brunswick Scientific Co., Inc.Inventors: Philip Snyder, David Freedman
