  • Method of forming conoid surfaces
    Patent number: 4217124
    Abstract: Conoid surfaces can be generated by rotation of a material at different angles and under differing constraints. An axis of 45.degree. can produce hyperboloids; with perpendicular axes, concentric spheres can be produced; magnetic fields can be used to shape the lenses; and multielement lenses can be produced with special chambers.
    Type: Grant
    Filed: December 6, 1976
    Date of Patent: August 12, 1980
    Inventor: Stephen Wyden
  • Hood with a cooling device and a precipitator
    Patent number: 4214455
    Abstract: A hood is disclosed which can be mounted over a work area or in a cooling tower. The hood can contain a cooling device and an electrostatic precipitator can be attached to the cooling device. A compressor and expansion chamber can be attached to the cooling device.
