Abstract: The apparatus for producing a desired quantity of ozone uses a flow of air in which a corona discharge utilizes high voltage to produce sparks. This apparatus includes a source of high voltage and the spark is produced when metal or conducting edge portions of the blades are moved in way of spaced conductors carried in a tubular confine. The blades are carried as an assembly which may be rotated by a flow of air. The flow of air and the turning of the assembly maintains the blades in a cooled condition so that unwanted burning of the edges of the blades does not occur. The corona discharged ozone may be used in swimming pools, or as an air purifier or dust eliminator. The ozone, when used in a closed building, will utilize a timer so an excess of ozone is not produced. The rotating of the bladed member is preferably by the flow of air, said volume of air flow regulates the speed of rotation.

Abstract: Disclosed is an all amine borane gas generating system which consists of razine bis-borane or its deuterated derivative in the form of a compacted solid propellant pellet which serves as the thermal stimulus for the decomposition of itself. An all amine borane gas generating system which additionally consists of diborane diammoniate or its deuterated derivative provides a higher yield of hydrogen or deuterium with a higher purity from a self-sustaining reaction after the self-sustaining reaction is initiated by a heat source (e.g., an electrically heated nichrome wire) sufficient to initiate the reaction. This all amine borane gas generating system which consists of N.sub.2 H.sub.4.2BH.sub.3 and H.sub.2 B(NH.sub.3).sub.2 BH.sub.4 is in the form of a compacted solid propellant pellet. The pellets are formed to the desired configuration employing pressures from about 500 to about 10,000 pounds total load. The solid propellant pellets are useful as a H.sub.2 or D.sub.2 generation sources for fuels for lasers.

Abstract: Bags of explosive are loaded rapidly into deep wellbores by suspending a rigid positioning tube partway into the wellbore, and loading the bags into the tube, the bags being prevented from dropping through the open bottom end of the tube by a cord attached to the lowermost bag and secured at the upper end of the tube when the tube-suspending cable is in tension by a cord-securing/releasing means, e.g., a pivotable bar having a hook on one end. When the bag-laden tube is lowered to the bottom of the wellbore, or to a column of bags previously placed therein, the tension on the cable is relaxed and the cord is released, allowing the positioning tube thereafter to be raised to the surface for re-use, leaving the cord and bags in the wellbore. Freedom of the bag-supporting cord to move with respect to the positioning tube when the latter is raised to the surface is assured by threading the cord through plastic tubing mounted to the wall of the positioning tube and releasable therefrom for re-use.
