Abstract: ABSTRACT:         "HALF-PITCH CAPACITOR INDUCTION MOTOR"      A balanced, half-pitch capacitor induction motor having a stator core member with equally spaced teeth equal in number to twice the number of motor poles and with the inner ends of the teeth having equal angular extent, and a squirrel cage rotor member.  The main field winding comprises serially connected coils equal in number to the number of motor poles respectively embracing alternate, consecutive ones of the teeth and being adapted to be connected across a single phase source of alter-nating current.  An auxiliary field winding comprises serially connected coils embracing consecutive teeth intermediate the teeth having the main winding coils thereon, the auxiliary winding coils being serially connected with a phase-displacing capacitor across the serially connected main winding coils.  The main and auxiliary windings have equal ampere turns and equal pitch thereby providing a balanced, half-pitch, two phase motor winding.  The rotor member has its squirrel cage bars spiraled by one-tenth of a full turn, i.e., two pole pitches of the 5th harmonic or 36° to eliminate the fifth harmonic in the speed torque curve.

Abstract: ABSTRACT      The invention relates to a spiral separator supported with its axis substantially vertically which is adapted to receive at an upper end thereof a pulp of water and minerals to be separated.  The spiral separator includes a plurality of helical turns wherein each turn has in vertical cross section a profile which includes a floor and an outer wall.  The outer wall is inclined upwardly relative to the floor.          The invention is characterized in that the floor alters in profile as the spiral descends and includes a radially inner part which extends to a substantially uniform radial distance from the axis and a radially outer part inclined upwardly at a steeper angle to horizontal than the inner part throughout part of the length of the spiral separator.  This feature provides a generally non-turbulent or laminar flow of pulp along the said part of the said spiral separator and thereby inhibits sand barring.

Abstract: METHOD OF RECONDITIONING WELDED JOINTS                 Abstract of the Disclosure This invention relates to a combined method of welding and annealing an aluminum-zinc alloy coated ferrous wire, and restoring the corrosion resistant properties to the annealed areas of said wire.   More particularly this invention is directed to reconditioning weld joints in aluminum-zinc alloy coated ferrous wire, where the coating consists of an aluminum-zinc alloy overlay and an intermetallic alloy layer, said intermetallic alloy layer being between said alloy overlay and the ferrous wire.  The preferred method includes the steps of (1) upset welding two aligned aluminum-zinc alloy coated steel wires, (2) annealing the weld joint, such as by electric resistant heating, at a temperature of between about 1200° and about 1450°F (649° and 788°C), whereby during such annealing the weld joint is subjected to brushing to remove said alloy overlay and to prevent the formation of oxides on said intermetallic alloy layer, (3) removing the burr formed during such welding, and (4) cooling.          During said cooling, or alternatively by reheating to a maximum temperature where the aluminum-zinc alloy coating on the wire begins to melt, i.e. about 900°F (482°C), a lead-free, Zn-containing solder stick or wire is repeatedly moved along the weld joint to further disrupt and remove any oxide remaining thereon while depositing a new corrosion resistant coating comprised of said lead-free, Zn-containing solder.          The resulting wire, having a corrosion resistant metallic coating along the weld area, may be bent tightly around a mandrel without the coating flaking off the wire.

Abstract: ABSTRACT           A method and apparatus for estimating shear wave velocities where such velocities are difficult or impossible to measure because the shear energy transmission is attenuated or its velocity is equal to or less than direct mud velocity or because the shear wave may not propagate at all under certain conditions.  The method and apparatus relate to an indirect technique for determining shear modulus by measuring the phase velocity of the Stoneley wave excitation and using it to estimate the shear modulus and the shear velocity.  Using at least two receivers, a window is placed over the Stoneley arrival of the wave detected at each receiver and the Fourier transform of each wave is taken.  The difference in phase of the Stoneley wave arrivals is determined.  The relative shear modulus involving the Lame constants is estimated by a procedure which includes matching two points on Stoneley wave dispersion curves.  From the relative shear modulus, the ratio of formation density to the density of mud, and the compressional velocity of the borehole mud is estimated the shear velocity.
