Apparatus for spraying glass bottle mold bodies, such as blanks and rings in a molding machine, includes nozzles and spray guns mounted on a plate such that the nozzles are positioned to spray the mold bodies with a material such as a lubricant during normal operation of the machine and without shutting the machine down. The apparatus can be installed on an existing machine without changing the molding machine. Rings may be sprayed while in motion during normal machine operation. A nozzle is provided along with check valves to produce a tight conical spray pattern.

Material application apparatus and methods

A method and apparatus is provided for combining two components to form a coating material formulation in which one of the components is a 'high volume' component comprising a resin including supercritical fluid as a diluent, and the other of the components is a 'low volume' component, such as a catalyst. The relative ratio of resin to catalyst is controlled by adjusting the catalyst pressure as a function of the pressure at which the resin is supplied to ,one or more coating dispensers and by adjusting the duty cycle of a catalyst valve within the catalyst flow path.

Apparatus for proportioning two components to form a mixture

A method and apparatus for combining multiple components to form a coating material formulation in which one of the components is a resin, another component is a supercritical fluid employed as a fluid diluent, and, preferably, the third component is a catalyst. Two of the components are transmitted through separate flow paths to a first mixer within which they are combined to form a mixture, and then the third component is added to the mixture in a second mixer to form the coating material formulation for discharge by one or more coating dispensers or spray guns onto a substrate.

Method and apparatus for forming and dispensing coating material

A gear pump for dispersing a gas into a liquid is provided with mixing means for improving the uniformity of the dispersion. In preferred form, the mixing means comprises a series of fixed, shallow, blind cavities that open to the pumping cavity between the liquid inlet and the outlet, and which are positioned to be 'wiped' by the gear teeth as the gears rotate. The alternate connection and disconnection of the intertooth spaces to these cavities as the gears rotate establishes motion or turbulence of the gas/liquid mixture within the intertooth spaces, and surprisingly improves uniformity of the dispersion.
