  • Patent number: 4790230
    Abstract: A portable modular music recording device which simply and unobtrusively attaches to a keyboard instrument for purposes of recording live musical performances; and an efficient music microcomputing system in which the captured musical data is digitized and further analyzed to determine note and note expression information when a key has been played. In the modular keyboard device, key and key expression data is captured by means of reflective couplers mounted in the keyboard device, and the information is transmitted to the processing unit. Microcomputer instructions refine the data to a format suitable for serial transmission via a computer-compatible link for ultimate scoring and recording.

  • Patent number: 4758304
    Abstract: The disclosure relates to a method and apparatus using ion etching and ion assisted deposition to reform a surface of an object, such as a large lens, from its existing topography to a predetermined topography. The method comprises comparing the existing topography of the surface of the object to the predetermined topography. In one embodiment, the comparison can be used to distinguish objects having surfaces which are readily or economically reformable to the predetermined topography from those which are not suitable for such reforming. The method novelly utilizes an algorithm comprising image restoration. The ion etching structure of the apparatus comprises an ion source grid which can be used to provide an ion beam of a preselected spatial distribution. The grid is constructed of a nonconducting, vacuum compatible material, such as a ceramic sheet coated with a conductive layer on each side. Apertures are drilled through the grid in a selected pattern.

  • Patent number: 4690341
    Abstract: The disclosure relates to an improved rotating impeller table for a secondary impact crusher comprising a side discharge port containing housing incorporating dove tailed abrasion resistant wear elements disposed on the external cylindrical wall thereof. The dovetailed wear elements overlap and are supported by removable lower edge wear liners which also protect the outer edge area of the lower part of the housing. A removable top liner retains the dove tailed elements in position and protects the upper part of the housing from abrasion. A removable and repositionable wear ring fits within an annular opening in the top of the housing and may be repositioned at least three times to essentially triple its wear life. Upper and lower centrufugally locking flat and ramped liners are disposed within the housing on its upper and lower ends.

  • Patent number: 4510556
    Abstract: An electronic lighting device for simulating a flame, particularly a candle flame. In the preferred embodiment a set of three vertically spaced lamps are enclosed in a translucent bulb and are controlled by a signal generator circuit which independently turns three lamps on and off in a manner which simulates both the illumination distribution and the gas turbulence in a natural flame. The circuit includes a multistage static shift register which is used in a feedback mode to produce three mutually delayed pseudo-random pulse trains. One pulse train is used directly to control the uppermost lamp. The other pulse trains are combined with assymetric long-duty-cycle and short-duty-cycle clock signals. The resulting combined signals are used to drive the lower and middle lamps, respectively.

  • Patent number: 4441024
    Abstract: A wide range radioactive gas concentration detector and monitor which is capable of measuring radioactive gas concentrations over a range of eight orders of magnitude. The device of the present invention is designed to have an ionization chamber which is sufficiently small to give a fast response time for measuring radioactive gases but sufficiently large to provide accurate readings at low concentration levels. Closely spaced parallel plate grids provide a uniform electric field in the active region to improve the accuracy of measurements and reduce ion migration time so as to virtually eliminate errors due to ion recombination. The parallel plate grids are fabricated with a minimal surface area to reduce the effects of contamination resulting from absorption of contaminating materials on the surface of the grids. Additionally, the ionization chamber wall is spaced a sufficient distance from the active region of the ionization chamber to minimize contamination effects.

  • Patent number: 4413447
    Abstract: A groove refinishing tool which utilizes a finishing wheel which is controlled by an air grinder motor. The air grinder motor is mounted on a main body section which is pivotally attached to a shoe element. The shoe element contains guide pins which guide the shoe element on the groove to be refinished. Application of pressure on the main body element compresses a weight counterbalance spring to extend the finishing wheel through the shoe element to refinish the groove surface. A window is provided for viewing the refinishing operation. Milling operations can also be performed by replacing the finishing wheel with a milling wheel.

  • Patent number: 4408463
    Abstract: The disclosure is directed to a wheel-type magnetic refrigerator capable of cooling over a large temperature range. Ferromagnetic or paramagnetic porous materials are layered circumferentially according to their Curie temperature. The innermost layer has the lowest Curie temperature and the outermost layer has the highest Curie temperature. The wheel is rotated through a magnetic field perpendicular to the axis of the wheel and parallel to its direction of rotation. A fluid is pumped through portions of the layers using inner and outer manifolds to achieve refrigeration of a thermal load.

  • Patent number: 4367657
    Abstract: The disclosure relates to a sludge sampler comprising an elongated generally cylindrical housing containing a baffle containing an aperture. Connected to the aperture is a flexible tubing having a valve for maintaining and releasing pressure in the lower end of the housing and exiting the upper end of the housing. The lower end of the housing contains a ball check valve maintained in closed position by pressure. When the lower end of the device contacts the sludge bed, the pressure valve is opened, enabling sludge to enter the lower end of the housing. After the sample is collected the valve is closed. An upsetting pin opens the valve to empty a sludge sample after the sample is removed from the fluid.
