Abstract: Abstract of the Disclosure Chlorates such as alkali metal chlorates, are made by electrolyzing brine in a cell having a plurality of compartments or zones therein, preferably three, wherein anode and cathode compartments are separated by a buffer compartment formed by perm-selective membranes of hydrolyzed copolymer of tetrafluoroethylene and a fluorosulfonated perfluorovinyl ether, or a sulfostyrenated perfluorinated ethylene propylene polymer, or by such a perm-selective membrane on the cathode side plus a porous diaphragm on the anode side, while reacting chlorine gas with the buffer zone contents in the zone or removed form it to a separate reactor vessel, while being under such conditions as to produce hydrochlorite and/or chlorate and chloride therein, converting any hypochlorite to chlorate and chloride in a liquid medium into the buffer compartment and a portion to the anode compartment and electrolyzing the chloride thereof. By such a process, with continued recirculation of the product solution until the chlorate content is sufficiently high, a relatively concentrated chlorate solution can be produced con-taining proportionally less chloride, due to its conversion to chlorate, and obviating the need for additional processing to remove chloride before chlorate could be obtained low in chloride and at an acceptable concentration.

Abstract: GROUND FAULT DETECTOR            Abstract of the Disclosure Techniques are disclosed for detecting and responding to a ground fault on either side of a two wire filtered, or unfiltered, power supply.  A first voltage divider is bridged across the lines of the power supply and an intermediate point is grounded.  A second voltage divider is bridged across the lines and two intermediate junctions provided.  First and second voltage responsive means are coupled from ground to the first and second junctions of said second voltage divider, re-spectively, for comparing the potentials between the coupled points and providing an alarm in response to a variation in-dicative of a ground fault on either line below a predetermined threshold impedance.  Filtering may be used to reduce the sensi-tivity of the system to noise or extraneous signals on the line.          The sensitivity of the entire system and/or either line to ground may be adjusted by changing the relative values of the elements of the voltage dividers.  The elements of the voltage dividers may be compared with the arms of a variation of the Wheatstone bridge.

Abstract: Abstract of the Disclosure Mechanism is provided for grooving or planing wood products either lengthwise or crosswise.  Such grooving may be preparatory to the interdigital end to end interfitting of work pieces, commonly referred to as finger-jointing, or to simple planing which involves the continuous, uniform smoothing of a surface from end to end throughout its entire width, or to uniform longitudinal or transverse slotting.  In any of these operations the cutting blade edges become dull and require re-sharpening from time to time.  Conventionally the outer face of the blade which confronts the work is ground away for sharpening, and this has the unfortunate consequence of shorten-ing the blade and thereby reducing the depth of cut.  In accordance with the present invention this difficulty is overcome. The blade is formed with parallel, upwardly and forwardly sloping inner and outer faces, and the blade is sharpened by evenly grinding away the forward face of the blade.  By pro-viding adjustable means on a blade carrying wheel for wedging the blade forward on an outward slope as far as possible, a blade which has had its forward face evenly ground away can be caused to pick up where it left off--to-wit, to cut to exactly the same depth as before resharpening.
