Patent number: 6740363Abstract: Provided is a method to produce high-temperature lubricious glassy films on silicon-based ceramics. The method comprises the steps of (a) oxidizing a silicon-based component, (b) coating the oxidized component with an alkali metal compound, and (c) heating the component to a high temperature in a sulfur-rich oxidizing environment. The steady state sliding friction coefficient values obtained with this system in 600° C. air are similar to those obtained with liquid lubricants operating under boundary lubrication conditions at much lower temperatures.Type: GrantFiled: April 17, 2003Date of Patent: May 25, 2004Assignee: The United States of America as represented by the Secretary of the Air ForceInventor: Lewis Rosado

Patent number: 6740048Abstract: A method is presented for determining diastolic intracranial pressure (ICP) in a patient. A first change in the length of a path across the skull of the patient caused by a known change in ICP is measured and used to determine an elasticity constant for the patient. Next, a second change in the length of the path across the patient's skull occurring between systolic and diastolic portions of the patient's heartbeat is measured. The patient's diastolic ICP is a function of the elasticity constant and the second change.Type: GrantFiled: September 25, 2002Date of Patent: May 25, 2004Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: William T.

Patent number: 6739548Abstract: The fin lock system overcomes the major problems associated with the current deployment and locking mechanism by adding a center boss to the fin between the rear and front bosses and a sliding lock that engages between the housing and the center boss. The sliding lock, having a very low mass, engages with the center boss, and thus with the fin, very quickly and reliably when the fin reaches its fully deployed position, thereby arresting the motion of the fin and preventing it from rebounding. This, in turn, allows the aft-housing lug to lock the fin in its deployed position with one opening motion of the fin. The additional boss provides greater resistance to inertial and aerodynamic loads while the sliding lock completely eliminates both over-rotation of the fin and inconsistent engagement of the fin lock.Type: GrantFiled: April 21, 2003Date of Patent: May 25, 2004Assignee: The United States of America as represented by the Secretary of the ArmyInventors: David A. Bittle, Russell S. Garner, Gary T. Jimmerson, Derek C. Jenkins

Patent number: 6740205Abstract: Incoming wastewater is preheated in a heat exchanger before delivery to a flash chamber through an orifice for flashing into water vapor rising into an upper section of the flash chamber which also has a bottom section into which liquid waste oil or other contaminants settles. Rise of such water vapor into the upper chamber section is induced by a vacuum established therein by a vacuum pump withdrawing the water vapor in a superheated and compressed condition for cooling within a condenser from which the incoming wastewater is delivered to a heat exchanger for preheating. The water vapor during rise into the upper section of the flash chamber is filtered to extract contaminates therefrom while liquefied water vapor thereafter formed therein is collected before the remaining water vapor is cooled into the condensate for collection within a distillate tank from which it is withdrawn for overboard discharge after being monitored for oil content.Type: GrantFiled: November 30, 2000Date of Patent: May 25, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventor: Henry J.

Patent number: 6740224Abstract: A process for manufacturing carbon nanotubes, including a step of inducing electrical current through a carbon anode and a carbon cathode under conditions effective to produce the carbon nanotubes, wherein the carbon cathode is larger than the carbon anode. Preferably, a welder is used to induce the electrical current via an arc welding process. Preferably, an exhaust hood is placed on the anode, and the process does not require a closed or pressurized chamber. The process provides high-quality, single-walled carbon nanotubes, while eliminating the need for a metal catalyst.Type: GrantFiled: June 11, 2002Date of Patent: May 25, 2004Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Jeanette M.

Patent number: 6738734Abstract: A computer implemented physical signal analysis method includes four basic steps and the associated presentation techniques of the results. The first step is a computer implemented Empirical Mode Decomposition that extracts a collection of Intrinsic Mode Functions (IMF) from nonlinear, nonstationary physical signals. The decomposition is based on the direct extraction of the energy associated with various intrinsic time scales in the physical signal. Expressed in the IMF's, they have well-behaved Hilbert Transforms from which instantaneous frequencies can be calculated. The second step is the Hilbert Transform which produces a Hilbert Spectrum. Thus, the invention can localize any event on the time as well as the frequency axis. The decomposition can also be viewed as an expansion of the data in terms of the IMF's. Then, these IMF's, based on and derived from the data, can serve as the basis of that expansion.Type: GrantFiled: December 10, 2001Date of Patent: May 18, 2004Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: Norden E.

Patent number: 6737099Abstract: Slurries of amylaceous flour from milled seed of cereals, beans, and legumes containing dispersed particles of starch-protein agglomerates are subjected to high pressure processing to obtain deagglomerated starch granules and protein. Further treatment of the deagglomerated product leads to the recovery of a novel protein-coated starch product or to the isolation of starch and protein of high purity and quality. The method greatly improves the recovery of starch during classification/separation from protein and is therefore economical. Starch reduced to individual granules, with low starch damage, low protein content, and with improved pasting characteristics, can be produced using this deagglomerization method. The protein obtained by the process has better solubility and is therefore suitable for beverage applications.Type: GrantFiled: March 29, 2001Date of Patent: May 18, 2004Assignee: The United States of America as represented by the Secretary of AgricultureInventor: Harmeet S.
