Abstract: Annular magnets, primarily for motor stators, are centrifugally cast from particulate materials and synthetic plastic materials. Iron particles and ferrite particles stratified during the spin casting procedures so that the former provide an outer stratum that serves as a yoke in the permanently magnetized structure. The anisotropic ferrite particles are magnetically oriented during casting by a rotating center magnet with the aid of bucking magnets that also rotate and serve to confine the field of the center magnet to the cavity area. Apparatus for carrying out the process is disclosed and includes means for introducing the plastic and particulate materials to the mold cavity while the mold is rotating as well as mold arrangements that facilitate material introduction by the creation of reduced pressure conditions in the cavity during the rotation of the mold.

Abstract: A system and method of moving near-surface water to a deep water aquifer at a high rate of transfer and with no external energy sources, and which additionally generates excess energy available for other uses. The system comprises at least one deep well into the deep aquifer and one or more shallow wells into a near-surface water table aquifer having siphon pipes from the shallow wells to the deep well. Siphon action is initiated resulting in a continuing flow of water from the shallow wells to the deep well. A water-driven turbine is disposed in the deep well above its tail water level and below the lower end of the siphon tubes. The water flow operates the turbine and the turbine shaft drives an external vacuum pump. Each shallow well has a closed top plate, and suction from the vacuum pump is applied through the top plate, holding the water level above its normal point increasing the draw down.

Abstract: The system of the present invention includes a sensor head which is coupled to an exteriorized artery. The sensor head includes electromechanical transducers at first and second locations which convert each periodic arterial pulse pressure wave passing the first and second locations into first and second periodic electrical waveforms.

Abstract: Apparatus for producing useful work from wave motion in a body of water. The apparatus translates wave motions of varying periods to continuous rotational kinetic energy which is then available to perform useful work. A float assembly is anchored off shore and communicates with the shore via a steel cable. The float rises and falls with the waves and is arranged to cause a reciprocating translational motion of the cable. A cable drum assembly is anchored to the ground on the shore and adapted to reel and unreel the cable by means of a rewind spring. As the cable unreels, the drum drives a transfer gear via a first ratchet which is therefore operative only in one direction. The transfer gear winds a heavy spiral energy storage spring via a second ratchet. The spring is attached to an anchor plate which drives a shaft. The shaft is coupled via a step-up gear train to an energy storage flywheel.

Abstract: An electroacoustic transducer having high acoustic-to-electric energy conversion per unit volume. The transducer is in the form of a body having a cylindrical central section and hemispherical end sections, the central section and the end sections formed from active piezoelectric material and electrically interconnected with respect to a pair of output terminals wherein the polarizations of the central section and the end sections are arranged to convert acoustic pressure on the entire external surface area of said body to be effective in producing electrical energy. The physical parameters of each section are matched to produce essentially equal electrical characteristics of each section to form an inherently symmetrical transducer. The transducer has high sensitivity for a small size and is especially adapted for use in thin line towed arrays. The symmetrical form, polarities and balanced connections of the transducer provide cancellation of forces due to acceleration.
