Abstract: A thread cutting insert comprises a center portion and a plurality of cutting corners project outwardly from the center portion. Each cutting corner comprises a pair of outwardly converging cutting edges which are joined together by a curved tip. Each cutting corner includes a chipbreaking protrusion extending upwardly higher than the upper face of the center portion of the insert. The protrusion includes a front portion facing the tip, and a pair of upwardly converging sides. The front portion and sides are spacially confined to the cutting corner.

Abstract: An improved process of the type wherein a fuel is first pyrolyzed in a chamber (14) and the resulting volatiles and non-volatiles then transferred to a combustion region (18) for burning, the improvement comprising temporarily storing at least a portion of the volatiles in an enclosure (24) spaced from the chamber (14) and the combustion region (18) when volatiles production exceeds the volatiles incineration capability of the combustion region. Apparatus for carrying out the method of the invention is also disclosed.

Abstract: An electrolytic cell is provided suitable for chloralkali electrolysis comprising a housing; an anolyte chamber in the housing; an anode disposed within the anolyte chamber; at least one cathode spaced from the anode with at least one portion of the cathode being adjacent said anolyte chamber, the cathode including a cathode chamber, means to supply and remove oxygen and remove alkali hydroxide catholyte from the cathode chamber; and a multi-layer wall defining a boundary between the anolyte chamber and the interior of the cathode chamber comprising a permeable separator material adjacent the anolyte chamber, a foraminous electrically conductive supporting material adjacent the interior of the cathode chamber, and at least partially hydrophobic electrocatalytically active material suitable for the reduction of oxygen adjacent the separator material and the supporting material.

Abstract: A method whereby an alkali, such as an alkali metal hydroxide, is produced at the cathode by the electrolysis of aqueous alkali metal halide solutions and the process is operated to produce either chlorine or HCl at the anode.

Abstract: A grinding element having a grinding section comprising diamond particles individually embedded in a resin binding medium with improved performance characteristics is provided, along with a method of making same. The improved characteristics are obtained by utilizing a metal coating on the diamond particles in the grinding section, which metal coating has a thickness of between 0.5 and 25 microns, preferably 5 to 20 microns, to impart to the section superior grinding properties to those which can be obtained with a like section wherein the diamond particles are not so coated.
