Vibratory signal sweep seismic prospecting method and apparatus

Abstract: Disclosed are a method and apparatus for vibratory seismic prospecting in which a vibratory signal sweep is produced by a vibrating apparatus in accordance with a power spectrum function S(f), which is proportional to a noise component function n(f) and a subsurface signal amplitude attenuation function B(f) for an area to be surveyed, to thereby produce reflection signals having an improved signal-to-noise ratio.

Integrated end stops for zipper slider

Abstract: A leakproof plastic zipper (11) with integrated end stops (23) for a zipper slider (10) particularly suited for thermoplastic bags (B). An increased flange height above the interlocking elements (16, 17) of the zipper (11) and an increased plow depth on the separator (9) of the slider (10) extending down between the flanges (18, 19) provide a means of stopping the travel of the slider (10) past the ends of the zipper (11). The separator structure (9) depending from the slider (10) has a configuration in vertical cross-section corresponding to an inverted T, the horizontal portion (9b) of the T having the ends thereof adapted to be received in window structure (18a, 19a) in the flanges (18, 19) above the interlocking elements (16, 17) and adjacent one of the integrated end stops (23).

Preliminary Experiments on a Microbial Fuel Cell

Abstract: Experiments were initiated to determine whether microbes using a hydrocarbon as food could generate electrical energy. Experiments with ethane were unsuccessful, but when microbes or glucose oxidase were added to a solution of glucose, electrical output was observed, confirming in part previous observations. As far as we know, no one had previously tested hydrocarbons in this manner, although the several effects of microbial activity on redox potential are well known. Failure of the microbes employed to dehydrogenate ethane in the absence of molecular oxygen is discussed in the light of recently published experimental evidence.
