摘要:
A fuel for splitting water into hydrogen and an oxide component comprises a substantially solid pellet formed from a solid-like mixture of a solid-state source material capable of oxidizing in water to form hydrogen and a passivation surface layer of the oxide component, and a passivation preventing agent that is substantially inert to water in an effective amount to prevent passivation of the solid-state material during oxidation. The pellets may be introduced into water or other suitable oxidizer in a controlled rate to control the rate of reaction of the source material with the oxidizer, and thereby control the rate of formation of hydrogen. Methods are described for producing the solid-like mixture in varying weight percent of source material to passivation preventing agent.
摘要:
The present invention relates to refrigerants generally, and more specifically to nonflammable, nonozone depleting, mixtures of refrigerants that may be substituted for HCFC-22, R-407C, R-417A, R-502, R-500, CFC-12, R-404A, HFC-134a, and others, and is usable in mineral oil systems. Among the most preferred embodiments of the present invention are mixtures that are substitutes for these refrigerants, comprising about 1 to 85 weight percent R-1 25, and about 1 to 80 weight percent R-134a, and about 0 to 12 weight percent of R-1270, R-290 or a mixture thereof, and about 1 to 15 weight percent R-E170 and about 0 to 20 weight percent R-227ea, with the weight percentages of the components being weight percentages of the overall mixture.
摘要:
A pile installation recording system for driven piles and auger cast piles. The recording system records a variety of parameter data received from sensing devices. The parameter data is stored, analyzed, and displayed to provide the operator with accurate and timely information regarding the pile installation. In addition, the parameter data may be stored on removable media, and further manipulated to generate a variety of reports regarding the pile installation.
