摘要:
Techniques, systems and material are disclosed for transport of energy and/or materials. In one aspect a method includes generating gaseous fuel (e.g., from biomass dissociation) at a first location of a low elevation. The gaseous fuel can be self transported in a pipeline to a second location at a higher elevation than the first location by traveling from the first location to the second location without adding energy of pressure. A liquid fuel can be generated at the second location of higher elevation by reacting the gaseous fuel with at least one of a carbon donor, a nitrogen donor, and an oxygen donor harvested from industrial waste. The liquid fuel can be delivered to a third location of a lower elevation than the second location while providing pressure or kinetic energy

In one aspect of the present invention, it is contemplated that a valve includes a passage. A first sealing element is biased to restrict flow of a fluid in a first direction through the passage when an upstream volumetric flow rate of the fluid in the first direction is less than a first predetermined threshold. A second sealing element is biased to unrestrict flow of the fluid to a baseline unrestricted flow rate in a second direction through the passage when an upstream volumetric flow rate of the fluid in the second direction is less than a second predetermined threshold.

Disclosed is a device for sensing the opening degree of a valve, which can easily determine the upper and lower limits without using upper and lower limit switches so that, besides simplifying the mechanical structure, the device can be easily installed, maintained, and repaired. The device can avoid basic errors and improve the opening degree sensing performance without using upper and lower limit switches, cams, and a spline so that, by simplifying the mechanical structure, the device can be manufactured, installed, maintained, and repaired at a low cost, and its long-term durability is improved. The device has a main gear adapted to disengage from the meter gear when the main gear is rotated excessively so that any damage to the meter gear and potentiometer, which may occur during installation or use, is prevented.

A fuel system for a mobile platform is provided. The system includes a crossfeed fuel transmission assembly having a single crossfeed valve that controls fuel consumption from a first fuel tank and a second fuel tank. The system additionally includes a balancing fuel transfer assembly fluidly connected to the crossfeed fuel transmission assembly. The balancing fuel transfer assembly includes a plurality of fuel balancing valves for controlling a transfer of fuel to the first and second fuel tanks. The fuel system further includes a fuel balancing controller for automatically controlling the fuel balancing valves to automatically control the transfer of fuel to the first and second fuel tanks.

A poppet valve assembly is provided for use on a fuel tanker truck which enables the truck's driver to determine whether fuel is flowing through the valve assembly and whether fuel is present in the valve assembly. The valve assembly has a two part housing, one of the parts having a sight glass secured therein. The sight glass is visible through cutouts in the housing. When the poppet valve is opened, fluid flows through a flow channel in the valve assembly. The fluid, being different colors, may be easily seen through the sight glass from a distance.

A fire protection system comprises a supply pipe having a first fluid pressurized to a first pressure and a network of pipes having a plurality of sprinklers. The network of pipes have a second fluid being pressurized to a second pressure at approximately 5.5 times the first pressure. The system further comprises a dry pipe valve including a body defining a passage extending along a longitudinal axis between an inlet coupled to the supply pipe and an outlet coupled to the network of pipes. The inlet has an inlet diameter of approximately WD inches and a seat disposed in the body has a seating surface with a diameter AD approximately less than two times WD inches. The dry pipe valve further includes a clapper pivotable about an axis orthogonal to the longitudinal axis between a first position occluding the passage when the ratio of the second pressure to the first pressure is at least 5.5 and a second position permitting fluid flow through the passage when the ratio is less than 5.5.
摘要:
A lamp for creating a decorative visual effect from the movement of fluids contained therein. In one form, the lamp features a tank having opposing front and rear surfaces that are substantially parallel to one another, at least one light source, a plurality of immiscible fluids of varying densities contained within the tank and a housing unit for aesthetically and functionally supporting the tank. The light source illuminates the liquids within the tank and can provide sufficient radiant heat to cause the temperature of the fluids within the tank to increase such that they become less dense. As the fluids within the tank become warmer and less dense, they begin to rise in the tank at varying rates and can create a dynamic visual display. In addition to the light source, alternative heat sources can be employed to provide added heat to the immiscible fluids within the tank.

Each of lines A, B is provided on each of opposite sides thereof with a tape heater 11, and a space for positioning a tape heater holding clip 13 therein is provided in each of locations between adjacent fluid control devices. The tape heaters 11 are held from opposite sides thereof to the line by the clip 13. The lines A, B provided with the heaters are each mounted on a line support member 10 removably attached to a base member 1. The line support member 10 has a heater insertion bore 14 formed therein and extending longitudinally thereof. A sheath heater 12 is inserted into the bore 14.

A seismic safety valve has a housing with a fluid inlet, a fluid outlet and a fluid passageway interconnecting the inlet and outlet. A recess is formed inside the housing along the fluid passageway, with a valve seat located adjacent to and below the recess. A valve member, made of a magnetic material, is in the fluid passageway and movable between a first position in the recess and a second position on the valve seat. The valve member closes the fluid passageway in the second position and opens the fluid passageway in the first position. The recess supports the valve member so that the valve member is movable from the recess upon the housing being subjected to a predetermined amount of seismic activity under forces generated by the predetermined amount of seismic activity and gravity. At least one electromagnet is on the housing outside of the fluid passageway. The electromagnet can be used to automatically activate the valve by moving the valve member, or may be used to reset the valve after the valve has been activated.
