Abstract: A method and apparatus for applying an impervious protective coating over the inside seam of a cylindrical metal can body either before or after the seam is welded, soldered or cemented and prior to spray coating the complete interior of the body. The apparatus is operable to practice the method of intermittently applying an airless spray to the interior seams of the cans as they continuously move past an airless spray gun secured to the end of a stubhorn of a can forming line. The nozzle orifice size and the nozzle orifice pressure are so selected and the nozzle so positioned and controlled that a thin smooth impervious layer of atomized spray is applied over the seam with a minimum of excess material being sprayed onto the seam surface and a minimum of waste material being sprayed past the seam surface.

Abstract: A high voltage electrostatic spray coating power supply which turns-off automatically when an overvoltage and/or overcurrent is detected, thereby reducing electrical shock and ignition hazards when spraying in an explosive atmosphere. Included is an unregulated DC supply, a DC voltage regulator, an inverter, and a multiplier of the capacitor/diode type which applies high DC voltage to an electrostatic spray gun. Ground return current from the multiplier output to a common internal ground lead is monitored and if it exceeds a predetermined selectable maximum is effective, via a turn-off circuit, to a) turn-off the DC regulator and b) short-circuit the regulator output and inverter input to the common ground. This prevents power transfer between the unregulated DC source and the voltage multiplier, as well as discharges electrical energy stored in the regulator smoothing capacitors and in the multiplier transformer. An overvoltage circuit is also included to independently turn-off the power supply when the regulator output voltage exceeds a predetermined maximum.

Abstract: A method and apparatus for spraying paint and similar coatings. In one form the paint is sprayed at low pressure from a flat fan nozzle. A flat fan of air impinges upon the fan of paint at an angle of from 30*-70*. The air atomizes the paint to form a soft spray with low forward velocity. In another form of the method, two fans of paint are projected toward one another at an angle and an air fan is directed along the bisector toward the zone of intersection. The air fan atomizes both streams of paint. An electrode can be placed in the air stream to ionize the air stream which in turn charges the paint particles. The width of the paint spray pattern is varied by varying the included angle of the air fan. A spray gun is disclosed having two tubular paint nozzles for projecting two fan-shaped fans of paint. An air nozzle is mounted between the paint nozzles for projecting a fan of air against the paint fans to atomize the paint. The air nozzle is adjustable to provide air fans of different angles for varying the width of the paint spray pattern. An electrode is disposed in the air nozzle for ionizing the air stream. This electrode is energized through a resistor and flexible cable. The cable is spring-urged toward the resistor so that when the resistor is removed, the cable shifts causing a safety switch to open deenergizing the gun. When a nozzle mounting member is removed, the cable and surrounding tube are shifted forwardly to automatically close a valve to seal off the air and electrical conduits. Removable caps are provided on the ends of the tubular paint nozzles for facilitating cleaning of the nozzles.

Abstract: A fluid operated system of modular guns for extruding or spraying liquids such as molten adhesives. The system includes multiple guns in the form of readily removable cylindrical modules that mount in apertures of a fixed service block or manifold which receives the supply lines for the liquid and the gun operating pressurized fluid. The service block and guns have passages which register when the system is assembled whereby the guns may be easily removed from the fixed service block and replaced without disconnecting any fluid lines or other service equipment.

Abstract: A control system for turning on and off an apparatus which discharges a coating liquid onto objects at a coating station. A sensor positioned adjacent the path of the objects upstream of the coating station initiates an interval timer as an object passes. After a predetermined time delay, the timer turns on a discharge gun positioned at the coating station, to begin to deposit the liquid upon the object. The timer maintains the discharge gun in an actuated condition for a predetermined time duration, and then turns the gun off. The control provides rapid and reliable turn on and turn off of the coating apparatus without false triggering, and provides precise time intervals which are continuously settable over an exceptionally wide range. The control utilizes a rapid reset hold and lock out circuit, SCR switches, unijunction relaxation oscillators having constant current charging circuits, an over voltage output circuit with short circuit protection, and means for programming the operation of plural discharge devices over different time periods.

Abstract: A hydraulic pump and double acting air motor therefor including means for controlling the inlet and exhaust of air to and from the opposite sides of the piston in the air cylinder. A pilot valve operated by the air piston controls one operating valve for the cylinder and a pilot relay valve. The pilot relay valve controls another operating valve which is in reverse phase with respect to the first operating valve. A muffler which inhibits ice formation is operatively associated with the operating valves for muffling the noise of the air being exhausted from the air cylinder through the operating valves with minimal accumulation of ice.
