A method and system for the spray application of epoxy materials is provided. The system includes a dual walled tank structure as a reservoir for containing and preheating the epoxy materials in preparation for mixing and spray application. Each component of the epoxy material is preheated before the components are mixed. After preheating, the components are then mixed together and spray applied. The method and system of the present invention provides a high quality spray applied epoxy coating while reducing equipment down time and cleaning.

A system for spraying objects in a field, wherein the system includes a treatment hoist connectable to a mobile platform main deck. The treatment hoist includes a treatment platform that is structured and operable to support and carry at least one treatment container, and at least one lift assembly. The lift assembly is structured and operable to lower the treatment platform to a loading position and raise the treatment platform to a dispensing position. In the loading position the treatment platform is lowered such that the treatment container(s) can be secured on the treatment platform in order to configure the system to dispense a desired solution, wherein the solution comprises at least one object treatment contained in treatment container(s). In the dispensing position the treatment platform is raised to a height above the objects in order for the system to dispense the solution onto the objects.

A mixing module includes two inlets, an integrator, and a valve member. The integrator has two chambers each having a near end and a far end, and the valve member is movable between two positions. One of the inlets is connected to the near end of one of the chambers and the other inlet is connected to the near end of the other chamber when the valve is in one position. When the valve is in the other position, one of the inlets is disconnected from the chambers and the near ends of the chambers are connected.

With the use of a low cost microphone mounted at each nozzle, a sound signature of the nozzles may be captured and stored to be used as a continuous indicator of any changes in the flow rate of the nozzles. By measuring changes in sound at each nozzle, it is possible to determine the change in flow before a change in pressure manifests into a problem in the system. The change in sound will oftentimes be significant for plugged nozzles, or nozzles that have excessive wear and flow at too high of a rate. The invention has the advantage of being relatively low cost with ceramic microphones, for example, and with little or no moving parts required. A closed loop control system may be included to compensate for nozzle degradation.

A coating device includes: a coating gun including a coating gun body provided with a jet and a cartridge detachably attached to the coating gun body and housing a first coating liquid; a transport body to which the coating gun is attached to move the coating gun to a predetermined coating position; and a relay tube provided to the transport body to connect a coating liquid supply source disposed in a position away from the coating gun and the coating gun. The cartridge includes a lead-out tube leading out the first coating liquid housed in the cartridge, and formed in the coating gun is a mixing space where the first coating liquid housed in the cartridge and the second coating liquid supplied from the coating liquid supply source are mixed is formed on a downstream side of the relay tube and the lead-out tube.

A sprayer equipment includes a support frame, a pump, a pressure regulator, a concentrate tank, an injector, a spray nozzle, and a controller. The support frame has a plurality of wheels. The pump is coupled to the support frame and includes a pump inlet configured to be fluidly coupled to a water source and a pump outlet providing water at an increased water pressure. The pressure regulator is configured to control the pressure of the water. The concentrate tank is supported by the support frame and configured to store a concentrate fluid. The injector is fluidly coupled to the concentrate tank and configured to inject the concentrate fluid into the water. The spray nozzle is fluidly coupled to the pump outlet and the injector. The controller is coupled to the injector and is configured to control operation of the injector.

A battery is provided with a battery cover having a first cover mold insert and a second cover mold insert which are interchangeable in the cover prior to molding depending at least in part on the battery's polarity configuration. The first cover mold insert has a bushing that is relatively different in dimension, size and/or shape than the bushing of the second cover mold insert, such that each bushing is adapted to receive a cast-on-strap post of a relatively different dimension, size and/or shape. The first cover mold insert may also have a terminal that is relatively different in dimension, size and/or shape than the terminal of the second cover mold insert, such that each terminal is adapted to engage a formation connector contact of a relatively different dimension, size and/or shape.
