  • Patent number: 5691516
    Abstract: A vibration absorbing device for a speaker enclosure is tuned upon installation to the speaker enclosure to achieve maximum attenuation of vibrations in a selected frequency range. The vibration absorber, which includes a series of vibration damping plates separated by spacers, is positioned at varying degrees of overhang on a mounting plate on a panel of the enclosure until attenuation of the desired frequency band is maximized. Then the absorber is secured to the speaker enclosure with an appropriately sized permanent mounting plate.

  • Patent number: 5629503
    Abstract: A vibration attenuating device for loudspeaker enclosures and other mechanical vibrating bodies includes one or more damping plates of viscoelastic material positioned to receive vibration energy transferred from the vibrating body. The vibration energy is transferred away from the speaker enclosure or other body and is dissipated as heat due to the internal molecular structure of the viscoelastic material, suppressing noise normally produced by the vibrating body. In various different embodiments, the vibration damping device includes damping plates shaped or mounted in such a way as to provide for attenuation of a wide band of frequencies of vibration. The damping plates themselves may each have a configuration providing for continuously varying frequency response along the length or circumference of the plate, and there may be included a plurality of different-sized plates, each responding essentially to a different frequency band.

  • Patent number: 5151084
    Abstract: A baffle with holes formed therein is mounted in a sleeve which surrounds the needle of an ultrasonic handpiece so as to reduce bubbles in the irrigation fluid supplied to the handpiece and thus improve the visibility at the operating site. As irrigation fluid is supplied to the handpiece, it contacts the ultrasonic motor which tends to cause bubbles and by providing the baffle with openings, the bubbles are restricted from passing the baffle and obstructing the vision of the surgeon using the ultrasonic handpiece.

  • Patent number: 5005773
    Abstract: A sonic generator comprises a resonant bar, a housing and magnetic excitation units connected between the resonant bar and the housing. The magnetic excitation units are connected to the bar at highly stressed points using a mounting connection which is a sleeve having an inside diameter slightly greater than the outside diameter of the bar. A resilient elastomer such as urethane is mounted between the sleeve and the resonant member. The sonic generator may be used for grinding purposes and, in particular, may be used to grind material exceptionally fine with reduced power consumption. The bar is substantially unrestrained so as to allow substantially free vibration.

  • Patent number: 4904168
    Abstract: A cassette and a cassette receptacle assembly are provided for use in an ocular surgical system. The cassette includes a housing which defines an arcuate race. A flexible tube extends across the race and conveys a fluid when compressed by the rollers of a roller pump. A slot is defined by the housing at the point where the tube forms a bend prior to entering the race. The slot has a height which is preferably smaller than the diameter of the tube and therefore prevents the tube from flattening as the rollers urge it away from the slot. The cassette mounting assembly includes a pair of cams which urge the cassette into a locked position with respect to the roller pump.

  • Patent number: 4660573
    Abstract: An improved ultrasonic lithotriptor probe for performing fragmentation and removal of calculi deposits in the kidney and upper ureter wherein high frequency sound waves are utilized to disintegrate the calculi or stones based on placing the probe against the stones and causing them to disintegrate due to the ultrasonic energy. The probe is coupled to a transducer which drives it and the probe is hollow and aspiration is utilized to remove the particles of the stone through the probe. The probe extends into the transducer which prevents the probe from clogging. Also, the end of the probe which engages the stone is provided with a slit so as to prevent it from being clogged by the stone so as to cause the aspiration to be interrupted when the end of the probe extends into the confines of the stone in that the split will allow liquid to pass through the probe and continue to cool it and to remove fragments through the probe.

  • Patent number: 4187170
    Abstract: A process for magnetically separating non-magnetic material from a mixture by combining the mixture with a magnetizing solution containing the salt of a magnetic element. The magnetic atoms attach to available sites on the molecules of the non-magnetic material so as to develop in that material a positive susceptibility. Thus the material is responsive to the influence of a magnetic field to move the material to a region where it can be analyzed or recovered. Materials with low positive or negative susceptibilities are separated by suspending them in a magnetic salt solution which when subjected to the attraction of a magnetic field develops a differential buoyancy force, pushing the diamagnetic or weak paramagnetic material strongly away from the magnet. Disclosed are solutions of ferric chloride, manganese chloride, erbium chloride, dysprosium chloride, terbium chloride, and holmium chloride.

  • Patent number: 4186387
    Abstract: A method of and system for sonifying a portion of a given area to rid the area of unwanted pests comprising providing at least one ultrasonic point source each producing a set of pulsed signals having a randomly varying frequency in the range of about 18-30 KHz and having an intensity of at least 90 dB at the periphery of a cone shaped area extending outwardly therefrom and having a predetermined maximum length and a predetermined maximum width. The point sources are spaced in the given area to maintain the minimum sound intensity level at any point in the sonified portion at not less than 90 dB by disposing point sources opposite one another when the distance therebetween is greater the maximum length, disposing point sources adjacent one another to effect a longitudinal overlapping of adjacent cones when the room width is greater than the maximum width and disposing point sources perpendicular to the adjacent point sources to sonify any dead space therebetween.

  • Patent number: 4081706
    Abstract: An improved oscillatory circuit in which the output of a radio frequency transformer is coupled from a half bridge squarewave amplifier to piezoelectric ultrasonic transducers through a serially connected feedback network. The feedback network employs a resistance connected in parallel with the serially connected combination of a capacitance, a feedback inductance and a feedback transformer. The improved feedback network provides a variable phase shift in feedback current to the half bridge squarewave amplifier tending to hold the frequency generated therein at a target frequency above anti-resonance.
