20090110803 | Control function and display for controlling spray gun - Control method and apparatus for a manual spray gun includes display that is disposed on the spray gun and that provides information to an operator about one or more coating operation parameters. An auxiliary trigger may be used that enables an operator to make selections or changes of one or more coating operation parameters. The display and auxiliary trigger together permit an operator to make selections or changes without having to divert attention or field of view away from the spray gun or the coating area, especially during a coating operation. The display may include numeric information, for example, data relating to a coating function being displayed. | 04-30-2009 |
20090110839 | Apparatus and methods for controlling material application device - Control method and apparatus for a manual spray gun may include a second manually actuated trigger disposed on the spray gun handle, with the second trigger being operational to select or change one or more coating operation parameters. | 04-30-2009 |
20100221125 | PUMP WITH SUCTION AND PRESSURE CONTROL FOR DRY PARTICULATE MATERIAL - A pump for particulate material includes a pump chamber wherein material flows into the pump chamber under negative pressure and flows out of the pump chamber under positive pressure. A plurality of pinch valves are provided to control flow of material into and out of the pump chamber. The pinch valves are operated independent of each other and of the pump cycle rate. A modular design of the pump is provided. A pump control feature is provided for air flow rate control during positive and negative pressure conditions. | 09-02-2010 |
20120009329 | CONTROL FUNCTION AND DISPLAY FOR CONTROLLING SPRAY GUN - Control method and apparatus for a manual spray gun includes display that is disposed on the spray gun and that provides information to an operator about one or more coating operation parameters. An auxiliary trigger may be used that enables an operator to makes selections of one or more coating operation parameters. The display and auxiliary trigger together permit an operator to make selections without having to divert attention or field of view away from the spray gun or the coating area, especially during a coating operation. | 01-12-2012 |

20140042238 | APPARATUS AND METHODS FOR CONTROLLING MATERIAL APPLICATION DEVICE - Control method and apparatus for a manual spray gun may include a second manually actuated trigger disposed on the spray gun handle, with the second trigger being operational to select one or more coating operation parameters. | 02-13-2014 |
20140245839 | POWDER FLOW DETECTION - Apparatus for detecting powder flow along a powder flow path includes a light source and a light detector for detecting light from the light source directed across the powder flow path as powder flows through said powder flow path. A circuit receives the output from the light detector and determines an average or RMS of the signal received by the light detector. The circuit may determine whether there is flow or no flow of powder or whether there is a change in flow rate of powder. Preferably, the apparatus is used in combination with a dense phase powder pump, which causes the powder to flow in pulses from the pump outlet into the powder flow path. More preferably, the light source and detector are enclosed in a housing that is connected between the pump outlet and a powder feed hose which supplies powder to a spray gun or hopper. | 09-04-2014 |
