Abstract: 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.

Abstract: In an apparatus for determining the moisture content of a material by measuring the dielectric constant of the material by means of a measuring conductor which is disposed such that the material becomes a dielectric for the measuring conductor and wherein the time lapse between the application of an electrical signal to the measuring conductor and the return of the echo of the signal is employed as an indication of the dielectric constant and consequently the moisture content of the material, the electrical signal is a pulsed signal with a pulse duration which is greater than the time lapse between signal start and return of the echo of the signal start and an independent oscillator is provided whose cycles are counted during the opening state of a gate circuit which is open between the application of electrical signal to the measuring conductor and the return of the echo thereof, the counted cycles thereby providing an indication for the time lapsed from signal start to echo return in a simple manner with si

Abstract: A device for the fine adjustment of an instrument table supporting an optical instrument which is operated by a control lever which is pivotally mounted to swivel in any direction to effect adjustment of the table in the horizontal plane and which is rotatable to effect vertical adjustment of the table.
