摘要： An explosion suppression system and triggering apparatus therefor are provided for quenching gas and dust explosions. An electrically actuated suppression mechanism which dispenses an extinguishing agent into the path ahead of the propagating flame is actuated by a triggering device which is light powered. This triggering device is located upstream of the propagating flame and converts light from the flame to an electrical actuation signal. A pressure arming device electrically connects the triggering device to the suppression device only when the explosion is sensed by a further characteristic thereof beside the flame such as the pioneer pressure wave. The light powered triggering device includes a solar panel which is disposed in the path of the explosion and oriented between horizontally downward and vertical. Testing mechanisms are also preferably provided to test the operation of the solar panel and detonator as well as the pressure arming mechanism.

摘要： A seismic signal receiving system is provided for use in boreholes to receive seismic waves in carrying out geophysical investigations. The system includes three pairs of opposed plates, each of the pairs of plates including oppositely facing outer surfaces for engagement with opposite sides of a borehole. A seismic receiver is mounted on the inner surface of each of the plates for receiving seismic signals. A double-acting, fluid-operated actuator selectively causes relative movement of the plates of the pairs of plates away from each other to provide expansion thereof so as to enable the plates to engage the walls of a borehole and selectively causes relative movement of the plates of the pairs of plates toward each other to provide retraction thereof so as to enable the system to be removed from a borehole. The pairs of plates each comprise a relatively long plate and a relatively short plate. An expandable linkage interconnects the long plates at the distal ends thereof. The plates are mechanically biassed into the retracted state so that the plates return to this state in the event of a system failure.

摘要： A method and apparatus for removing selenate from waste water through the use of selenate respiring microorganisms under substantially anoxic conditions is described. The method includes a first zone for removing nitrate by assimilation into biomass. The first zone is maintained under aerobic conditions and is separated from a second zone where selenate is respired to elemental selenium by selenate respiring microorganisms under anoxic conditions. Biomass produced in the first zone may be processed to provide nutrients and electron acceptors for the maintenance of selenate respiring microorganisms when selenate becomes growth limiting. An optional sulfate reduction zone is provided in the method and apparatus where hydrogen sulfide is produced. The hydrogen sulfide so produced is circulated to the second zone and may be used to reduce residual selenite to elemental selenium.

摘要： A method of producing magnetite is disclosed which comprises culturing a microorganism designated GS-15 in the presence of organic matter and a ferric iron compound. Unlike prior art production of magnetite using magnetotactic bacteria, GS-15 is able to produce large amounts of ultrafine-grained magnetite extracellularly under anaerobic conditions, allowing for easy separation and recovery of the magnetite without the need for rigorous control over oxygen tensions in the culture medium. As a result, the method of the present invention can be used to mass produce magnetite efficiently using inexpensive means and materials.

摘要： A method for recovering sulfur from a solid sulfur-containing catalyst is disclosed which comprises contacting the catalyst with liquid anhydrous ammonia in order to leach the sulfur out of the catalyst, and form an ammonia-sulfur solution. The sulfur is recovered by separating the ammonia from the solution, preferably by evaporation. The catalyst used in this method is also rendered suitable for reuse. The principal utility of the invention is in the ultimate conversion of phosphogypsum, produced primarily in the fertilizer industry, into sulfur so that it can be recycled back into the industry.
