Patent number: 7000691Abstract: An apparatus includes heat-generating structure disposed in an environment having an ambient pressure, and a cooling system for removing heat from the heat-generating structure. The cooling system includes a fluid coolant, structure which reduces a pressure of the coolant to a subambient pressure at which the coolant has a boiling temperature less than a temperature of the heat-generating structure; and structure which directs a flow of the liquid coolant at the subambient pressure so that it is brought into thermal communication with the heat-generating structure, the coolant then absorbing heat and changing to a vapor. A method for cooling heat-generating structure disposed in an environment having an ambient pressure includes providing a fluid coolant and reducing a pressure of the coolant to a subambient pressure at which the coolant has a boiling temperature less than a temperature of the heat-generating structure.Type: GrantFiled: July 11, 2002Date of Patent: February 21, 2006Assignee: Raytheon CompanyInventor: Richard M.

Patent number: 6735086Abstract: A heat-conducting device for conducting heat between a circuit board and an airframe of a missile includes a thermal plane onto which the circuit board is mounted, and a pair of feet that partially protrude from the slots in the thermal plane. Slot-engaging portions of the feet freely float within the slots, allowing repositioning of the feet in two dimensions relative to the slots. Resilient devices such as springs urge outer portions of the feet into contact with the airframe. Locking mechanisms may prevent extension of the feet until after the heat-conducting device is installed in the missile. The feet self-align into contact with the airframe, automatically adjusting to compensate for misalignment and/or warping.Type: GrantFiled: May 13, 2003Date of Patent: May 11, 2004Assignee: Raytheon CompanyInventors: Richard M.

Patent number: 5852563Abstract: A coolant distribution system and method for a plurality of devices requiring cooling where the coolant source is of limited capacity. The system and method apportion coolant to each of the devices requiring cooling based upon instantaneous knowledge of the waste heat load of the devices. This is accomplished by providing a scheduler, which is preferably a computer having a data base, to concurrently determine the instantaneous amount of coolant apportioned for each of the devices. In response to this determination the flow of coolant from the coolant source to the devices is controlled in accordance with the apportioned flow of coolant for each device based upon a predetermined schedule. The coolant flow rate is controlled by providing a controllable valve coupled to the coolant source, determining the flow rate of coolant through the valve and a flow controller responsive to the scheduler and the determination of the flow rate of coolant through said controllable valve to control the controllable valve.Type: GrantFiled: March 14, 1997Date of Patent: December 22, 1998Assignee: Raytheon TI Systems, Inc.Inventors: Richard M. Weber, James F. Kviatkofsky

Patent number: 5507150Abstract: A thermal management system using an expendable liquid which undergoes phase change to a vapor as waste heat is absorbed and also possesses a high latent heat of vaporization. The vapor is expelled, carrying with it the waste heat. A vacuum source lowers the vapor pressure to lower the vaporization temperature. In first embodiments, regulated fluid flows into a heat exchanger wherein a vacuum system lowers the pressure. Waste heat transported to the heat exchanger by a coolant loop causes the liquid to boil at a desired temperature. A flow regulator controls the rate of fluid flow from the pressurized reservoir to the heat exchanger. The refrigeration effect is produced by the liquid being converted from the liquid to the vapor phase and absorbing heat from the coolant fluid during the phase change. The vacuum system provides a system pressure that results in a suitable temperature at which vaporization occurs. The fluid flow is controlled, based upon the demand from the heat load produced.Type: GrantFiled: February 4, 1994Date of Patent: April 16, 1996Assignee: Texas Instruments IncorporatedInventors: Richard M. Weber, Donald C. Price, Byron E. Short, Jr.

Patent number: 4855967Abstract: The disclosure relates to a seismic vibrator having an airbag isolator, a transducer for monitoring the instantaneous air pressure within the airbags, a summer to add the pressures within each air bag and a calibrated weighting network to convert the composite pressure for display as holdown weight on a meter and for comparing the measured holdown against a preset threshold that is used to enable or disable sweep generation or operation of an inducer. The system also includes structure for comparing the measured holdown against a preset threshold that is used as a feedback signal to the lift system and for providing a signal proportional to holdown weight to the sweep generator for use as a feedback signal to modify the amplitude of the force generated by the actuator.Type: GrantFiled: December 22, 1988Date of Patent: August 8, 1989Assignee: Halliburton Geophysical Services, Inc.Inventors: John J.

Patent number: 4682669Abstract: A transportable hydraulic seismic transducer has a seismic energy source connected to a pad for imparting elastic waves to the underlying ground. The energy source has a reaction mass with a single diameter cylinder formed therein, a double ended piston reciprocally mounted in the cylinder with a piston rod extending from opposite ends of the piston and a pair of bushings fitted within the cylinder at opposite ends to provide bearing surfaces for the opposite ends of the piston rod. A piston may be ringed and a liner fitted into place within the cylinder with the rings forming a seal with the liner. The piston may also be ringless and a liner made of a bushing material fitted within the cylinder so that between the piston and the liner, an adequate seal is provided. The use of the single diameter cylinder or bore permits the total machining of inserted parts such as the bushings and liners to be done before inserting in the reaction mass bore.Type: GrantFiled: February 18, 1986Date of Patent: July 28, 1987Assignee: Texas Instruments IncorporatedInventor: Richard M.

Patent number: 4450928Abstract: A dual mode vibrator (DMV), in its hydraulic cylinder, automatically provides a shorter stroke for higher frequencies and a longer stroke for lower frequencies. The cylinder contains a pair of sleeves, each sleeve having one diameter portion sufficient to slideably engage the piston and having a smaller diameter portion to slideably engage the piston rod. The sleeves themselves are moveable within the cylinder, such movement being effected by the application of high pressure on one end or the other. When the sleeves are moved together, the stroke is effectively shortened. When the sleeves are moved apart, the stroke is effectively lengthened.Type: GrantFiled: August 3, 1981Date of Patent: May 29, 1984Assignee: Texas Instruments IncorporatedInventors: Richard M. Weber, John W. Bedenbender
