  • Patent number: 5289921
    Abstract: Granule cleaner and method comprises a hollow elutriation column into which dust- and debris-adulterated pellets are blasted on a high velocity air stream through an upwardly inclined injection tube to form a floating suspension in said column. Suction withdraws the lighter suspended material from the top while the heavier particles fall to the bottom. A.C. electrostatic dischargers diametrically disposed opposite conductive portions of the injection tube which may be ground-isolated (and also opposite ground-isolated conductive portions of the column below the injection level of the granules therein) to neutralize both the entering contaminated granules and the falling cleansed pellets, the conductive ground-isolated portions defining reference electrodes for balancing ion emission.

  • Patent number: 5245503
    Abstract: Apparatus for conveying a stream of air in a fanned out distribution pattern over a work surface without use of diverting vanes comprises a duct having an inlet end coupled to the discharge of a tangential blower and an open outlet end for delivering a predetermined volume of air therethrough. The shape of the duct gently flares outwardly from the inlet to the outlet to provide a wider but flattened configuration in the direction of the air path although the cross-sectional areas of the inlet and outlet ends of the duct are substantially equal, whereby air exiting from the duct covers a broader yet extended range. Incorporating an A.C. static eliminator in the duct adjacent the outlet yields a uniform field of air ionization.

  • Patent number: 5017876
    Abstract: Apparatus for measuring corona current in high voltage A.C. ionizers uses an electrical sensor adjacently spaced from at least one of the discharge electrodes and coupled to electronic circuitry for separating capacitive current from the corona current. In one mode, the capacitive current component is measured directly by a first sensor adjacently spaced from one discharge electrode whose corona current flow to such electrode is either obstructed or squelched entirely while a second sensor monitors total current. The signals from the two sensors are electrically subtracted when applied to opposing inputs of a differential amplifier to provide an output signal proportional to just corona current. In a second mode, a measure of corona current is again provided by electrically subtracting from a total current signal input to a differential amplifier a signal equal to the capacitive current component.

  • Patent number: 4846172
    Abstract: Transocular and periocular laser delivery system for treatment of eye diseases wherein a fiberoptic element is passed through a perforation made either by paracentesis of eyeball encapsulating tissue (i.e.-cornea, sclera) or by the fiberoptic element itself so that the fiber actually penetrates into a chamber therein. The penetrating fiber end is then juxtaposed to the tissue to be treated while the external fiberoptic end is coupled either to an excimer laser emitting ultraviolet radiation (in the range of 193 to 351 nanometers) or to certain lasers emitting infrared radiation, the radiated pulses therefrom being directed through the transocularly-positioned fiber to be absorbed by chromophores in the target tissue (cataractous lens, trabecular meshwork, vitreous membranes, tear duct occlusion) where removal by photoablation is effected.

  • Patent number: 4749196
    Abstract: An alignment element for a golf club formed of a transparent material having first and second references marks. The reference marks are oriented upon the element so that when the element is affixed to a golf club, preferably a putter, the second reference mark is magnified when the first reference mark is oriented between the viewer and the second reference mark. Preferably the second reference mark is a contrasting color, lighter than the first reference to give the appearance, when viewed from above, of a darker line superimposed on a lighter magnified line. When affixed to a golf club, the alignment of the first reference mark with the magnified second reference mark is used to assist in positioning when addressing the ball.

  • Patent number: 4665462
    Abstract: Ionizing gas gun for ultra-clean static neutralization comprises a plastic nozzle enclosing positive and negative ion discharge electrodes and means for blowing a gas, such as air or nitrogen therethrough. A trigger actuates both the release of gas and application of positive and negative high voltage to the respective discharge electrodes, including delay circuitry for suspending discontinuance of the positive high voltage to its electrode for a momentary period subsequent to discontinuance of the negative high voltage when the gas is cut off in compensation of a slight preponderance of negative ion emission otherwise effected at cut-off. Venturi ports at the nozzle tip draw air over the discharge electrodes for admixing with higher mobility nitrogen ions when nitrogen rather than air is employed as the blowing medium. A changeable filter insures cleanliness, including monitoring means to indicate clogged or ruptured filter conditions or improper installation.

  • Patent number: 4558309
    Abstract: A monitor for sensing any break in electrical continuity between a body and earth when the body is coupled to earth by way of a grounding tether used to prevent build-up of static charges on such body. The monitor includes an oscillator circuit for generating A.C. output voltages which are adapted to actuate an alarm. Body capacitance and resistance are coupled by way of the tether across an impedance network either in the tuned circuit determining oscillator frequency or in the output load thereof whereby the resistance or inductance of the impedance network provides the path to ground for the body through its tether. With body capacitance and resistance components of the total impedance, variable elements in the impedance network are adjusted to diminish the circuit output voltage below the threshold voltage required to actuate the alarm when continuity exists while developing an output voltage level sufficient to actuate the alarm when a break in continuity occurs.
