Abstract: METHOD OF RECOVERING METALS OUT OF SOOT             ORIGINATING FROM THE COMBUSTION OF OIL                                Abstract Soot produced in the combustion of fuel oil contains valuable metals, such as vanadium and nickel.  The soot can be disposed of, and the valuable metals can be recovered, by leaching the soot with an aqueous solution of sulphuric acid, to extract part of the metal content from the soot, combusting the soot thus leached, and leaching the combustion residue with an aqueous solution of sulphuric acid, to extract an additional part of the metal content.  The solution produced in this second leaching process is preferably returned to the leaching of the soot.  Metals can be recovered in a way known per se from the solution produced in the leaching of the soot.

Mounted on the standard is a flexible wand including a flexible primary wand portion fixedly secured at its lower end to the standard and at its upper end to a plate and a secondary flexible wand portion secured at the upper end to said plate and slidably adjustable at its lower end upon the lower end of the primary wand so that slinding movement of the secondary wand portion upon the fixed primary wand portion causes the primary wand to assume a position from vertical to any arced position between vertical and substantially at 90° position depending-upon the wind currents and the speed of "jigging" desired.          Mounted on the standard is a reel having a supply of fish line, the line extended from the reel to the outer end of the wand on which is mounted stop members which grippingly and releasably engages the line.  As wind currents hit the plate the wand moves up and down and the line with a bait thereon moves up and down.  The line releases from the wand when a fish grabs the bait.  Movement of a live minnow on the line creates a greater movement of the wand action.

Abstract: ABSTRACT OF THE SPECIFICATION:     A presser member, into which the container is loaded, is manually depressable against the action of its return spring into pressure-contact engagement of the container with an electric heating plate containing a PTC heating resistor. The depression stroke produces closure of a switch to energize both the PTC resistor and an electromagnet keeping the presser member in its depressed condition. A timer circuit opens the switch at the elapse of a prealably experimentally determined heating time during which the liquid reaches its consumption temperature, whereby heating is terminated and the return spring lifts the pressure member with the container to unloading position. The heating process comprises a fast initial heating period until the PTC resistor temperature reaches a predetermined maximum value, and the consumption temperature of the liquid is reached by inter mittently energizing the PTC resistor at short intervals (fraction of a second) in. a high-temperature range directly adjacent said maximum value without exceeding the latter.
