Abstract: A coating apparatus with a powder supply system for use in a device for electrostatically spraying powder material onto the surface of an article or substrate to be coated. The system includes a powder reclaiming and recycling system which pneumatically retrieves the unused powder from the spray booths and filters the powder from the air. The filter system includes plural modules, each capable of accommodating a given number of spray guns. An automatic filter shaking system releases the powder from the filters upon command by sequentially shutting down the filter modules, one at a time, while the system is in operation. An additional filter module is provided so that adequate filtering capability is maintained while the filter shaking operation proceeds. The powder released from the filters is blown from the filters to a feeder section through a sieve which mixes new powder with the reclaimed powder under automatic control which replenishes the powder supply to the feeder. The feeder employs a fluidizing bed from which (a plurality of) plural module feeders are fed. The feeders are positioned beneath the bed and draw powder through elongated standpipes for improved powder flow control. This configuration shows complete drainage of the bed and prevents ''''puffing'''' associated with conventional fluidized bed feeders. The feeders are quickly and easily detachable from the system and can be quickly and easily replaced or disassembled for cleaning when material or color change is desired.

Abstract: An electrostatic spray apparatus and method for spraying electrically conductive coating materials on a continuous basis from an electrically grounded bulk coating supply. Included is a spray gun from which electrostatically charged coating material is emitted toward an electrically grounded object to be coated; a high voltage source for electrostatically charging the coating material emitted from the gun; an electrically grounded bulk coating storage tank; and an intermediate tank assembly including (a) an inner tank for continuously supplying coating to the gun via a hose, which inner tank is automatically and periodically replenished with coating material from the grounded bulk supply tank without establishing an electrically conductive path between the electrically grounded bulk storage tank and the inner tank which contains coating material electrostatically charged via the column of conductive coating material in the gun hose, (b) an electrically grounded outer housing or container completely enclosing the inner tank, and (c) an insulative support electrically isolating the inner tank from the outer grounded container, which support is subjected to a gaseous stream to prevent build-up thereon of a conductive film of coating material which, if permitted to occur, would shortcircuit the grounded outer container to the electrostatically charged coating material stored in the inner tank and thereby destroy the electrical isolation between the inner tank and the grounded outer container.

Abstract: An improved combination filter, check valve, relief valve cartridge for use in a hot melt applicator system of the type which includes a reservoir in which the hot melt material is heated and from which it is pumped through a manifold block to an applicator gun. The cartridge is so constructed that it may be installed or removed from the block as a unit and the filter may be separately removed for cleaning or replacement.
