Patent number: 4155372Abstract: An apparatus for removing concentrations of liquid from a natural gas pipeline comprising a tap valve mounted on the pipeline at the upper portion thereof so as to be in communication with the interior of the pipeline. A siphon apparatus is removably mounted on the tap valve and includes a siphon pipe which is vertically movably mounted with respect to the tap valve. The siphon pipe is vertically movable from an upper position wherein the lower end of the siphon pipe is positioned above the tap valve to a lower position wherein the siphon pipe extends through the tap valve so that the lower end of the siphon pipe is positioned at the bottom interior of the pipeline. A discharge pipe extends from the siphon pipe and is in communication with a liquid holding tank. A siphon valve is imposed in the discharge pipe to permit the selective removal of the liquid from the pipeline.Type: GrantFiled: September 12, 1977Date of Patent: May 22, 1979Assignee: Northern Natural Gas CompanyInventors: Walter C. Mills, James W. Patterson

Patent number: 4123196Abstract: A turbomachine such as a compressor having one or more rows of blades designed to operate at a supersonic inlet relative Mach number is provided with a manifold surrounding the blade tips for extracting air from the passages between adjacent blades by an amount generally inversely related to the inlet relative Mach number, thereby restructuring the shock pattern. Extraction rate is modulated by a valve operatively connected to the turbomachine fuel control system.Type: GrantFiled: November 1, 1976Date of Patent: October 31, 1978Assignee: General Electric CompanyInventors: David C. Prince, Jr., Carl C. Koch

Patent number: 4073305Abstract: An elongated tube is bent to have a central portion, a short leg and a long leg. The long leg is closed by a cap which is counterbalanced into the closed position. An elongated inner tube having an outer upper end passes through the sidewall of the long leg and terminates a substantial distance down in the long leg of the outer tube. The outer end of the inner tube is covered by a conventional bulb air pump. Squeezing the air pump pushes a pulse of air out the lower end and creates a vacuum when the cap is closed to begin siphoning through the short leg.Type: GrantFiled: May 20, 1976Date of Patent: February 14, 1978Assignee: Belshaw Brothers, Inc.Inventors: Amos J. Brown, Thomas E. Belshaw, Kenneth L. Knull, Wilbur D. Wilke

Patent number: 4050243Abstract: A combination injector/port cover for a solid fuel ramjet (SFRJ) having a be-in-hole injector which uses two seals to lock the tube into the air inlet and injector port during the boost phase, and which moves the tube into the combustion chamber during transition to the sustain phase.Type: GrantFiled: May 17, 1976Date of Patent: September 27, 1977Assignee: The United States of America as represented by the Secretary of the NavyInventors: Allen L. Holzman, William J. Corcoran

Patent number: 4025008Abstract: An air intake control for an air utilizing jet aircraft engine. The control is provided with fixed and movable air intake control ramps and the positioning of such movable ramps for air control purposes is determined by the static pressure above one thereof modified by the static pressure of the external air flow, the total pressure and the angle of attack of the aircraft. One control parameter is produced by a device responsive to the relationship between the static pressure above the one movable ramp and the total pressure of the external air flow. Particularly, this pressure relationship is calculated as a function of the operating cylinder feedback signal indicating the actual position of the center ramp, and is applied as a modifying value to a summing junction provided in the control circuit to produce a variable demand signal.Type: GrantFiled: May 11, 1976Date of Patent: May 24, 1977Assignee: Messerschmitt-Bolkow-Blohm GmbHInventor: Juergen Peikert

Patent number: 3974648Abstract: A variable-geometry ramjet engine, capable of operation over the Mach 3 to 12 speed range, is provided by disposing a movable cowl around a centerbody. The engine is axisymmetric and features a translatable cowl which slides relative to the centerbody on circumferentially spaced radially extending support struts. Forward translation of the cowl provides a variable inlet area resulting in higher compression at the high Mach numbers than is possible with a fixed-geometry configuration. Rearward cowl translation increases the combustor length and combustor area ratio at the low flight Mach numbers to improve low-speed combustion characteristics. Cowl translation changes the nozzle area ratio to provide a large expansion ratio at high flight speeds and a low expansion ratio at the low flight speeds.Type: GrantFiled: August 19, 1968Date of Patent: August 17, 1976Assignee: United Technologies CorporationInventor: Charles Edward Kepler

Patent number: 3948283Abstract: The invention contemplates an improved rotary-syphon construction whereby condensate may be syphoned from the inner wall of a rotating drum, for example, a steam-heated dryer. The improvement resides in the particular construction whereby syphon parts are axially removably insertable through a journal bearing at one end of the drum, and whereby internally projecting parts of the syphon derive direct and firm radial-positioning support, thereby relieving syphon-tube parts from any need to sustain the stress fluctuation which would otherwise result from reliance upon cantilevered support of the syphon-tube parts solely at the journal-bearing region.Type: GrantFiled: June 26, 1973Date of Patent: April 6, 1976Inventors: Abraham C. Miselem Asfura, Abraham A. Miselem Alfonsa

Patent number: 3941335Abstract: An ejector wing, for an aircraft, having inlet and diffuser doors which move from an open take-off configuration to a closed forward flight configuration and having hypermixing nozzles and root nozzles for supplying primary air into a plurality of channels in the wing structure. Apparatus is provided for controlling the air flow from the root nozzles in the boundary layer in the channels. A plurality of sensing ports are provided in the channels upstream of the root nozzles. The differential pressures at the sensing ports are used to divide the flow to the root nozzles on opposite sides of the channels.Type: GrantFiled: June 19, 1975Date of Patent: March 2, 1976Assignee: The United States of America as represented by the Secretary of the Air ForceInventor: Hermann Viets
