Abstract: A vessel for containing an electro-conductive fluid, the vessel having a laminated wall structure and including an outer structural shell, an inner corrosion-resistant lining  made  of  electrically  non-conductive  material, constituting a barrier between the structural shell and electro-conductive fluid in the vessel.   An electrically resistive medium is mounted between the structural shell and the corrosion-resistant lining, the resistive medium carrying an array of electrodes mounted in spaced apart relationship  at  fixed  and  known  locations.    A  main electrode  is mounted in the vessel extending into the electro-conductive  fluid  which forms  an  electric path between the main electrode and the resistive medium in occurence of a fault in the corrosion-resistant liner, such that electro-conductive fluid is allowed to contact the resistive medium.  An electronic controller impresses a voltage difference across electrodes of the array for causing  electric  current  to  circulate  through  the resistive medium.   The controller obtains voltage drop measurements   across   the   resistive   medium   between electrodes of the array and the  contact point of the electro-conductive  fluid  on  the  resistive  medium,  to determine the location of the fault, each of the voltage drop measurements being between a respective electrode of the array and the main electrode.

Abstract: A novel lightweight gas-metal composite is produced having isolated particle-stabilized pores.  A composite of a metal matrix, e.g. aluminum, and finely divided solid stabilizer particles, e.g. silicon carbide, is heated above the liquidus temperature of the metal matrix and this is mixed such that a vortex is formed.  The molten composite is blanketed with a gas and during the vortex mixing.  This gas is drawn into the melt to produce an expanded, viscous molten composite material containing pores which are very small, spherical-shaped and quite evenly distributed.  The viscous molten composite material can be directly formed into a solid shaped product and is also capable of being remelted and formed by forming processes without destroying the integrity of the pores.  The result is a lightweight expanded metal product capable of being formed into shapes to close dimensional tolerances.
