Abstract: A system includes processing circuitry and a drone. The drone includes a dispenser subassembly that includes a housing comprising an aerosol dispensing system and configured to receive a syringe such that an applicator of the syringe is positioned distally from the housing; a trigger that is positioned in contact with a nozzle of the aerosol dispensing system; an actuator arm; and an actuator motor configured to move the actuator arm in a reciprocating motion. Control logic of the drone is configured to navigate, based on navigation instructions received from the processing circuitry, the drone to an area associated with an object of potential survey interest (OoPSI) such that the applicator of the syringe or the nozzle of the aerosol dispensing system is proximate to the area associated with the OoPSI.

Abstract: An engine friction monitor uses commanded torque and measured torque to provide a prognostic feature to identify failure modes of an engine that causes the engine from delivering the commanded torque.

Abstract: Photocatalysts and methods of making and using the same are disclosed. The photocatalyst includes a TIO2 ultra-nanoparticle having a single Fe, Co, Mn, Cr, or W atom positioned as an engineered defect within the particle and a single metal catalyst atom bound proximal to the single Fe, Co, Mn, Cr, or W atom. The method of making the photocatalyst includes generating a plurality of ultra-nano TIO2 particles, each having a single Fe, Co, Mn, Cr, or W atom positioned as an engineered defect within the particle. The method further includes photodepositing a single metal catalyst atom proximal to the single Fe, Co, Mn, Cr, or W atom for at least a portion of the ultra-nano TIO2 particles, thereby creating the disclosed photocatalyst. The single metal catalyst atom is in a positive oxidation state and can be Pt, Pd, Ir, Ru, Rh, Os, Re, Au, Ni, Zn, or Cu.

Abstract: Assets of broadcast network content are targeted to network users of interest based on location information regarding user equipment devices. Asset providers can specify location targeting criteria via a graphical user interface displaying mapping information. This location targeting criteria can then be compared to location information regarding user equipment devices so that assets are delivered to appropriate devices. The comparison of the location targeting criteria to the device location information can be performed at the user equipment devices or at another location. In the latter case, the assets can be addressed to appropriate user equipment devices or appropriate user equipment devices can be directed to select the asset, which is broadcast via the network. In this manner, assets can be targeted to individual network users on a basis independent of network topology.

Abstract: A manifold tube is formed from a straight length of thin wall tube initially having a uniform circular cross section. A first segment of the tube is left in its initial circular cross section configuration. The first segment includes an inlet end of the tube. A second segment of the tube is flattened to form opposed flat wall portions spaced apart by a distance smaller than the diameter of the circular portion and separated by side walls spaced apart by a distance greater than the diameter. An inlet fitting is attached to the inlet end of the tube. A bend is formed in the first segment of the tube between the inlet end and the second segment. Burner valves and on oven control valve are secured with metal-to-metal contact to the flat wall portions in the second segment of the tube.

Abstract: A method and apparatus for use in impregnating an absorbent fibrous layer or similar portion of a tubular liner with a curable resin material to prepare such a liner for installation into a pipe to repair the pipe. Several vacuum applicators such as hollow needles, all connected to a vacuum, are used simultaneously to evacuate air from the entire absorbent fibrous layer of the tubular liner, beginning at a time significantly before curable resin is first introduced to be absorbed. A timer is used to begin the evacuation automatically.

Abstract: A paraffin refill or package system or article wherein the paraffin mixture is provided in a large total volume which has preselected portions or sub-volumes which are defined by a divider structure. The sub-volumes or portions are preferably cube shaped. In use, a single carton containing the paraffin refill or system is opened. One or more portions or cubes of the system are added to the bath apparatus reservoir and heated. The user then observes the resultant liquefied mix to determine whether additional portions of the system are necessary. Any remaining portions of the system are saved in the carton.

Abstract: A valve adapted to be disposed in a conduit for a flowing substance which may be a liquid or gas comprises a lower valve housing for allowing fluid under pressure to enter the valve. As flow under pressure enters the valve body it forces a float ball to float inside the valve body. When a rupture in the conduit occurs and allows the flowing substance to exceed the normal amount of pressure, the float ball rises to and engages an upper valve housing ball seat where the float ball sits thereby sealing and shutting off the valve from escape of the flowing substance. When the problem has been rectified, the valve can be reactivated by removing a lock member and simply pressing a reset button.

Abstract: A speed control actuator includes a diaphragm forming a movable wall of a variable pressure chamber. An output member is fixed to the diaphragm to impart diaphragm movement to a throttle valve of the automotive vehicle. Three solenoid valves are mounted on a common bracket and are disposed in the variable pressure chamber for controlling vacuum and atmospheric pressure into the chamber. Two of the three solenoid valves are normally biased open to assure disengagement of the actuator.

Abstract: Disclosed is a fluid pressure and signal controller (60) that is adapted to regulate a fluid pressure regulator (16) by means of rotation of a cam (24) in response to rotation of a shaft. The controller is additionally provided with means for generating signals at one or more predetermined positions on the cam by movement of an output member (48) that is in contact with a profiled surface (40, 40') of a body member (38) which in turn is caused to move in response to movement of a cam follower (42) that is in contact relationship with the cam. Means are provided such as threads (51) are provided for adjusting the rotative position of the body member with respect to the position of the cam follower to account for any change in the initial position of the cam member and to enable more than one of the signal generation means to be positioned at different locations about the cam.

Abstract: A quick vent response valve (12) is fluidically series connected between a vacuum regulator valve (14) and an exhaust gas recirculation valve (16) which comprises a fluid pressure control system (10). The quick response valve operates to vent the system more quickly than if the system were vented through the vacuum regulator valve itself by employing the modulated control signal from the vacuum regulator valve as a pilot signal. The quick response valve improves response time of the vacuum system when venting from a high to a low vacuum level by momentarily displacing a valve element (56) disposed within a housing (18) to establish a nonrestricting flow path to atmosphere.

Abstract: A fluid pressure and electrical signal controller for providing a predetermined regulated vacuum signal from a variable source in response to changes in position of a rotatable input shaft when attached thereto and an electrical signal at a predetermined position of the input shaft. A pressure force balance type vacuum modulator valve is preloaded and biased by a spring connected to a cam follower which tracks a rotary cam turned by the input shaft. The modulator valve is slidably attached to the controller body for adjusting the preload length of the spring and a rotatable adjustment ring engages the valve and is threadedly received on the controller body for effecting sliding adjustment of the valve position on the controller body.
