Abstract: A method for generating a hydride gas of metal M1 in an electrochemical cell comprising a cathode comprising metal M1, a sacrificial anode comprising metal M2, an initial concentration of aqueous electrolyte solution comprising a metal hydroxide, M3OH, wherein the sacrificial metal anode electrochemically oxidizes in the presence of the aqueous electrolyte solution comprising M3OH to form a metal salt, and the hydride gas of metal M1 is formed by reducing the metal M1 of the cathode. The method comprises the steps of determining solubility profile curves of the metal salt as the M3OH is consumed and the metal oxide is formed by the oxidation reaction at various concentrations of M3OH; determining a maximum concentration of M3OH that, as it is consumed, does not yield a concentration of metal salt that precipitates out of the electrolyte solution; and choosing a concentration of M3OH that is in the range of at and within 5% less than the maximum concentration of M3OH to be the initial concentration of M3OH.

Abstract: A locking plate fast fastening ceiling fan blades includes a clamp plate. A chute is formed on the clamp plate, where a pushing board is contained. The clamp plate in the chute is provided with a first wedge unit and a thru hole. Thus, when a set of blades is installed on a blade rack of a ceiling fan, only the blade is set around several pillars on the blade rack, the clamp plate of fixing plate is set to locate on the pillar, and a pillar is made to pass through the thru hole. The pushing board of fixing plate is shifted toward the pillar, making the front end of pushing board stay close to the side of pillar and the first wedge unit of clamp plate stay close to the terminal of pushing board for fast and exact completion of fixing of the blade onto the blade rack.

Abstract: Systems and methods are disclosed for measuring sulfur trioxide/sulfuric acid content of flue gas. A probe is provided that extracts two separate lines of gas samples simultaneously from the flue gas. One of the two lines is dynamically spiked with a known quantity of sulfur trioxide, preferably generated in the probe. A comparison of sulfur trioxide/sulfuric acid content measurements from the spiked and unspiked lines helps identify and adjust for inherent biases in the measuring system. Also disclosed are catalyst structures and methods for use thereof for generating sulfur trioxide at known concentration.

Abstract: A pneumatic rotary tool comprises a housing, a square drive output member supported by the housing for rotational movement, and a pneumatic motor disposed in the housing for driving rotation of the square drive. A valve is disposed in the housing for rotary movement between a first position in which pressurized air powers the motor in a forward direction and a second position in which pressurized air powers the motor in a reverse direction. An actuator supported on the housing for translational movement is connected to the valve by a lost motion connection system. The lost motion connection system comprises first and second connector elements that are engaged for generally conjoint movement in a first direction and for relative sliding movement in a second direction generally perpendicular to the first direction.

Abstract: A hydrogen dispensing station and method of operating a hydrogen dispensing station for dispensing to multiple receiving vessels. The station and method limit receiving vessel gas temperature during dispensing. Various components used to limit receiving vessel gas temperature during dispensing are mutual to multiple hydrogen service ports. Receiving vessel gas temperature during dispensing may be affected by pressure ramp rate control, cooling of hydrogen in a heat exchanger, and/or use of a lower temperature hydrogen source stream.

Abstract: A method of combustion and a reformer. The method includes combusting a fuel in combustion region of an up-fired or down-fired reformer and forming non-uniform injection properties with a wall-bound burner. The combusting is performed in a combustion region by burners, wherein at least one of the burners is the wall-bound burner forming the non-uniform injection properties. The non-uniform injection properties generate a heat profile providing a first heat density proximal to a wall and a second heat density distal from the wall, the second heat density being greater than the first heat density. The non-uniform injection properties are formed by injection properties selected from an angle of one or more injectors, a flow rate of one or more injectors, an amount and/or location of oxidant injectors, an amount and/or location of fuel injectors, and combinations thereof.

Abstract: A solid fuel rocket burn rate control employing electrical energy preheating of the fuel grain at a plurality of locations dispersed over the grain burn face cross-section as a thrust control arrangement. The electrical energy of the preheating is generated by electrical battery cells which are dispersed across the grain cross-section and are triggered from an inert state into energy generation by burn face heat. The preheating situs moves continually in response to movement of the grain burn face; this is achieved through the use of high temperature electrical battery cell materials responding to the approach of the grain burn face by increased chemical activity and decreased electrical resistance. Preferably, the preheating is directly accomplished by the heat from electrical and other losses in the battery cells.

Abstract: A fermentation process uses substantially pure oxygen. The oxygen is the only reactive gas which is injected into a fermentation vessel. The oxygen is moved through the vessel solely by its own pressure. The process can be used with both mechanically-agitated and air-lifted fermenters. The mechanically-agitated fermenter includes an analyzer for measuring oxygen concentration in the exhaust line, and adjusting the flow of fresh oxygen into the vessel accordingly. In the air-lifted fermenter, an analyzer measures the oxygen concentration in the head space of the vessel, and operates valves which either recycle the gas from the head space, or vent that gas to the outside, according to the measured concentration. A stream of nitrogen is periodically injected into the vessel to drive out carbon dioxide and other gases, to control the pH of the fermentation medium. The present invention substantially improves the efficiency of a commercial fermentation process.
