Abstract
For supplying frit slurry to the sealing surface of a funnel portion of a cathode ray tube, air under pressure, preferably saturated with a solvent for the frit slurry, is supplied to a vessel containing the frit slurry, and the latter is transported by the air under pressure out of an outlet of the vessel and through a hose or hoses for deposit on the sealing surface. The flow of frit slurry is regulated by a valve between the vessel outlet and the hoses. The frit slurry contained in the vessel is stirred continuously to maintain a substantially constant slurry viscosity as the slurry leaves the vessel outlet.
Claims15
An apparatus for applying viscous material to a surface of an article comprising:
- supply means for providing a gas under pressure;
- saturating means for saturating said gas with a vaporized solvent for said viscous material to deter drying of the latter when exposed to the saturated gas under pressure;
- and
- containment means for containing said viscous material and to which said saturated gas under pressure is supplied, said containment means having an outlet through which said viscous material is forced by said saturated gas under pressure for application to said surface.
A method of applying a viscous material to a surface of an article which comprises the steps of:
- pressurizing a gas;
- saturating said gas with a solvent for said viscous material;
- and
- applying said saturated gas under pressure to a vessel containing said viscous material and having an outlet through which said viscous material is forced by said saturated gas under pressure for application to said sealing surface.
