Abstract: A method of geochemical prospecting where samples of soil, sediment and rock in a geological area are collected and each sample is contacted with a leach solution of water, glucose and glucose oxidase. The oxidase acts upon the glucose to produce gluconic acid and hydrogen peroxide. The leach solution reacts with manganese dioxide carrying trace metal elements and compounds in the samples to produce a leach reaction solution.      The leach reaction solution and the residue of the said sample are separated, and the leach reaction solution is analyzed to determine the trace metal content present. From the analysis, the mineral content of the geological area is predicted. The leach solution may also contain ascorbic acid, catalase, galactose oxidase and a salt such as water soluble metal cyanides and water soluble metal halides.

Abstract: A continuous pressure driven adsorption process for separating a multi-component gaseous mixture. In accordance with the method, the multi-component gaseous mixture is passed through a first portion of the adsorbent to adsorb one or more preferentially adsorbed components while a second portion of the adsorbent is regenerated.  The multi-component mixture is passed through the first portion of the adsorbent in sections and the second portion of the adsorbent is regenerated in sections. The sections forming the first portion of the adsorbent become successively less saturated and the sections forming the second portion of the adsorbent become successively more concentrated in the more preferentially adsorbed component. A product stream is expelled from the less saturated section of the first portion of the adsorbent. The product stream is enriched in the less preferentially component(s). Masses of adsorbent are continually being shifted between the first and second portions of the adsorbent so that the mass of adsorbent forming the regenerated section is shifted to the first portion of the adsorbent and used to form the least saturated section. The mass of adsorbent forming the most saturated of the sections is shifted to the second portion of the adsorbent and used to form the non-regenerated section. The masses are shifted at a sufficiently high frequency to maintain the sections forming the first and second portions of the adsorbent in their successively less saturated and successively more concentrated states.

Abstract: An induction logging tool is disclosed for utilization in conjunction with surface electronic equipment for measuring a characteristic of subsurface formations. A transmit signal which is comprised of a repetitive sequential series of at least three transmit frequencies is generated by coupling an oscillator to a transmitter coil and a plurality of selectable tuning capacitors. A signal characteristic of the response of the formation to this transmit signal is detected at a receiver coil array and two phase sensitive detectors are then utilized to generate output signals indicative of the magnitude of the X and R components of the formation signal which is in phase with a reference phase signal. The output signal of each phase sensitive detector is then utilized to accurately determine the X and R component of the receiver coil signal for each frequency by nulling the output of the phase sensitive detector utilizing a closed loop conversion circuit which eliminates errors due to phase and gain variations. The X and R signals from two or more frequencies are then utilized to correct for skin effect in both magnitude and spatial response.

Abstract: An improved log siding system capable of providing an improved water-shed between the individual log siding members as attached to a building. A moisture seal junction and a flex gap are formed between each adjacently disposed log siding member. Each moisture seal junction extends from the lower longitudinal edge of the exterior surface of each log siding member upward (vertically or angled inward) toward the respective flex gap, which extends therefrom toward the interior surface of the log siding members. The interspacing of each flex gap, in conjunction with a release cut formed in the interior surface of each log siding member, varies in response to structural deformations experienced by the log siding members due to variations in moisture content and/or temperature so as to maintain flush seal of each moisture seal junction. This effectively thwarts the ingress of moisture behind the log siding members so as to reduce the likelihood of swelling, rotting, and cracking over time.
