Abstract: System for conveying and dispensing material may include a heated supply of the material, one or more heated hoses, a heated dispenser, and a pump having a heating device internal the pump. A pump for conveying liquid or liquefied material, for example chocolate, may include one or more heating devices disposed within the pump. A filter may also be provided with an optional internal heating device.

Abstract: A spray nozzle assembly includes a nozzle tip and a nozzle tip adapter. The nozzle tip adapter may include a visually perceptible indicia that corresponds uniquely to an offset angle value of the nozzle tip adapter. In one embodiment, the visually perceptible indicia may comprise a unique color for each offset angle among a selectable group of nozzle tip adapters. Another feature is a locator tool that includes an adjustable holder that is fixed in position relative to a spray nozzle tip or orifice during an alignment operation, and repositioned away from the nozzle tip during a spraying operation. The adjustable holder may include a measurement member to determine one or more distances between the nozzle tip or orifice and a location on a workpiece that will be coated or sprayed.

Abstract: An apparatus for generating ultraviolet light and irradiating a 450 mm diameter semi-conductor wafer. The apparatus includes a plenum and an array of nine RF irradiator units coupled with the plenum. Each irradiator unit includes a plasma lamp bulb and an RF generator operable to generate a radiation energy field to excite the plasma lamp bulb and emit the ultraviolet light. The nine irradiator units are arranged in three rows with three of the irradiator units in each row.

Abstract: An apparatus for generating ultraviolet light for irradiating a substrate. The apparatus includes a housing enclosing an interior space. The housing includes an inlet for receiving a cooling air flow, and a window configured to emit ultraviolet light and discharge the cooling air flow. A lamp bulb is mounted within the interior space between the inlet and the window. First and second microwave generators are mounted between the inlet and the lamp bulb. A plate is positioned between the inlet and the first and second microwave generators, the plate at least partially defining a plenum within the housing and including first and second openings generally aligned with the respective first and second microwave generators to direct first and second portions of the cooling air flow at the first and second microwave generators.

Abstract: A spray nozzle assembly includes a nozzle tip and a nozzle tip adapter. The nozzle tip adapter may include a visually perceptible indicia that corresponds uniquely to an off-set angle value of the nozzle tip adapter. In one embodiment, the visually perceptible indicia may comprise a unique color for each offset angle among a selectable group of nozzle tip adapters. Another feature is a locator tool that includes an adjustable holder that is fixed in position relative to a spray nozzle tip or orifice during an alignment operation, and repositioned away from the nozzle tip during a spraying operation.

Abstract: A nozzle assembly for a material application device includes an expansion chamber for slowing down the velocity of powder fed to the nozzle from a dense phase pump. The nozzle assembly includes a nozzle insert that forms the expansion chamber and provides air assist function. The nozzle includes an integral deflector, and further includes a passageway for a charging electrode so that the electrical path is routed away from the powder path, while permitting the electrode tip to be centered in the powder spray pattern from the nozzle. The nozzle also includes air wash for the electrode. The nozzle outlet orifice has a cross-sectional area that is equal to or greater than the inlet cross-sectional area so that a slow moving dense phase powder cloud is produced by the nozzle.

Abstract: Purge arrangement for powder coating system includes a gun manifold (40) that is selectively assembled for fluid communication with either a purge manifold (36) or a hopper manifold (34). This allows purging of multiple hoses and guns at the same time and simplified color change operations.
