Abstract: A process for producing sodium hypochlorite slurries admixes a hypochlorous acid solution having a concentration of 35 percent or greater by weight of HOCl with sodium hydroxide at a temperature below about 25.degree. C. The reaction produces a slurry of sodium hypochlorite pentahydrate in an aqueous solution of sodium hypochlorite where the sodium hypochlorite is present in a concentration of at least 35 percent by weight of NaOCl. The sodium hypochlorite slurries have improved stability and greatly reduced amounts of sodium chloride. The process for produces high strength sodium hypochlorite compositions of high purity having improved yields and reduced product decomposition.

Abstract: A multiple module EFP warhead comprises a tubular body having a central axis with a plurality of explosively formed penetrator modules arranged tandemly within the body along the axis. Each of the modules includes a curved, dish shaped support disk having a unique forwardly convex curvature. The support disk is focused on the axis at a point behind the module. Each module has a set of circumferentially spaced apertures therethrough, each having a central aperture axis intersecting the central axis. Each aperture supports a separate ductile metal disk therein and an explosive charge behind and against the metal disk. Each of the aperture axes forms an acute angle of inclination with the central axis which is uniquely offset from the axes of the other modules so that each EFP travels along a unique forward path.

Abstract: A particular side frame design for use in an electromechanical cell with a catholyte flow pattern is disclosed wherein the cell is angled from the horizontal and the catholyte is fed into a gap in the cathode compartment between the liquid metal cathode and the membrane on the lower first end and exits the gap on the opposing higher second outlet end. The side frame is obliquely angled on the interior of the cell to prevent the escape of the flowable liquid metal cathode and to prevent contact of the acidic catholyte with the cell bottom.

Also claimed is the elastomer produced by the above method utilizing a one-shot technique.

Abstract: In a backup mode of operation a process control program sends messages, via a local area network, to a process control program running in an active mode for the purpose of obtaining current values of process control data and configuration information. If the active process control program fails to respond to an interrogation by the backup process control program the backup program automatically activates itself to assume the active role. The activation procedure includes a sequence that transmits a control pulse of predetermined width on a line of an associated process control bus to a novel digital data switch. The receipt of a valid control pulse causes the digital data switch to allow access by the backup (now active) data processor to process control I/O unit(s) while simultaneously isolating the active (now backup) data processor from the I/O units.

Abstract: A particular side frame design for use in an electrochemical cell with a catholyte flow pattern is disclosed wherein the cell can be generally horizontal or angled slightly from the horizontal and the catholyte is fed through a transition area into a gap in the catholyte compartment between the liquid metal cathode and the membrane on a first end and exits the gap on an opposing second outlet end. The side frame has opposing sides that are obliquely and downwardly angled in the corners to support the membrane in a wrinkle free manner so that the membrane is obliquely positioned between the liquid metal cathode and the anode. The membrane is above the level of the catholyte where the catholyte enters and exits the catholyte compartment, but drops to a level below the entry and exit points.

Abstract: An apparatus for use in space environments to control the flow of a propellant to a thruster at a low mass flow rate comprises an insulated body having a cavity therein defining a vaporizing chamber, a porous medium having a low liquid permeability disposed in the chamber, a conduit means for feeding a propellant liquid into the chamber and exhausting a propellant vapor from the vaporizing chamber, and a heating means communicating with the medium within the chamber for controllable heating of the liquid propellant in the chamber creating a variable liquid/vapor transition zone within the medium. The transition zone is responsive to the heating means to control the mass flow rate of propellant through the vaporizing chamber. As the liquid/vapor transition zone is moved upstream by increasing the heater output, and thus increasing the volume of vapor within the porous medium, mass flow through the porous medium is decreased.
