  • Multi-purpose paint and varnish stripper
    Patent number: 5332526
    Abstract: This invention provides a paint stripping composition comprising N-methyl-2-pyrrolidone and lower alkyl ethers of propylene glycol and dipropylene glycol. The composition does not include any toluene, halogenated hydrocarbons, acids, caustics or waxes and is not harmful to a wide variety of substrates.
    Type: Grant
    Filed: March 15, 1993
    Date of Patent: July 26, 1994
    Inventor: Donald E. Stanley
  • Apparatus and method for spent solvent collection
    Patent number: 5330579
    Abstract: An apparatus and method are provided for use in removal of coatings from airplanes and the like wherein such removal requires the application of a solvent composition for dissolving the coating such as paint, the solvent having a sufficiently high vapor pressure to be present in both a liquid phase and a gaseous vapor phase at stripping temperatures with the solvent in the vapor phase being lighter than the liquid phase and heavier than air, and the apparatus including a portable carriage, positionable beneath the airplane, a receptacle having spaced side walls and carried by the carriage, the side walls extending vertically upwardly, the receptacle further defining a receptacle bottom portion, the receptacle receiving spent solvent in both the liquid and the vapor phases after application of the solvent to the airplane surfaces and dissolution of the paint therein, the side walls directing the received spent solvent in both phases to the receptacle bottom portion such that vapor phase is trapped above the he

  • Organ stop switching system
    Patent number: 4173167
    Abstract: An organ stop switching system includes a plurality of stop switches and a random access memory within which combinations of stop switch settings are stored. The stop switch settings are multiplexed into a memory loop having a capacity fractionally smaller than the random access memory. This loop is used for an input and an output circuit for the random access memory during time slots corresponding to numbered pistons selected for storing and recalling stop setting combinations. A serial-to-parallel converter receives information from the memory loop and provides outputs for operating stop control circuitry of the organ.
