Abstract: An improved method for detecting very low concentrations of luminescent reactive molecules from microbial cells in samples of fluids and degraded solids is disclosed. A sample containing microbial cells is treated to eliminate substantially all nonmicrobial material. The microbial cells are then caused to rupture and form a thin film positioned in the vicinity of a photodetector. An appropriate reagent contacts the thin film and the resulting photon emission is observed by the photodetector through an optical filter means which selectively restricts the wavelength of photons which are permitted to pass from the sample to the detector. The strength of the luminescence within the permitted wavelength is measured and recorded as an indication of the concentration of microbial cells in the sample.

Abstract: The present invention relates to a method of extracting gold from placer gravel. Whereas conventional techniques are relatively effective in the processing of coarse gold particles, i.e. plus ten mesh tyler, the present invention finds application in recovery of gold particles of all sizes from submicroscopic through coarse nuggets larger than ten mesh tyler. A rotating sluice box uses centrifugal force to enhance the sluicing process, and a centrifugal amalgamator then extracts gold from the concentrate thus produced, under centrifugal force. Gold is removed from the mercury by conventional techniques.

Abstract: A method of delaying a signal N period lengths of a timing signal is disclosed using two shift registers which have capacities y and z, each less than N, but which have a total capacity greater than N. The signal to be delayed is fed to a first shift register until that shift register is full. The signal is later fed to the second shift register. When N bits of information have been recorded by the shift registers, the first shift register is again inputted causing an output which corresponds to the first data bits of the signal. Thus, there is stored in both registers y+z-N bits of common data during each cycle. This cycle is repeated for each N periods of the timing signal, thereby resulting in the storage of N data bits by a plurality of shift registers which each have a capacity less than N which have a total capacity greater than N.
