  • Patent number: 9724719
    Abstract: Systems and methods for producing consistent spray patterns and for diminishing clogging experienced when applying spray adhesive from a spray gun are provided. One system includes an automatic non-atomizing spray valve operably coupled to a first and second flow valve. The spray and flow valves are electronically controlled using logic running on a processing unit. The logic is programmed to carry out a spray cycle that involves dispensing a first liquid from the spray valve (first phase) and then dispensing a second liquid through the same spray valve (second phase). Because the first liquid (e.g., water-based adhesive) has the potential to clog a nozzle of the spray valve, a short burst of the second liquid (e.g., cleaning fluid) is introduced to prevent the nozzle from clogging. The spray valve is configured as a pulse width modulated spray gun to further reduce clogging and to generate an evenly distributed spray pattern.

  • Patent number: 9644838
    Abstract: A combustion system for operational connection to an energy conversion system and a method of providing thermal energy to the energy conversion system. The system comprises a combustor to be oxy-fired at above atmospheric pressure, using solid, liquid or gaseous fuels, with a supply of oxygen and supercritical carbon dioxide. The combustion gases from the combustor are delivered to a heat exchanger which interfaces with the energy conversion system. Temperatures in the combustor, and the delivery temperature to the heat exchanger, are controlled by selective recirculation of at least part of the combustion gases to the combustor, and by modulating the supply of oxygen and fuel to the combustor. Any combustion gases which are not recirculated are processed to separate carbon dioxide for use or sequestration. The system and method substantially eliminate emissions of carbon dioxide, while providing a highly efficient supply of thermal energy to the energy conversion system.

  • Patent number: 9468164
    Abstract: An automated irrigation purge system utilizes a pressure purge method of discharging compressed air from a reservoir through selected irrigation zones with feedback from pressure switches to determine when to open and close each zone valve. No programming or user interaction is required beyond starting the system. The system can operate with a wide variety of irrigation systems, with varying number of zones, pipe lengths, pipe diameters, number and variety of sprinkler heads or outlets, and terrain slope. The system tracks the pressure transition time from high pressure to low pressure for each zone as it is blown out. When the current transition time is within a specified range from the previous transition time, the system knows the water has been sufficiently purged from that zone. The purge system can protect the irrigation system from high-pressure conditions, handle multiple error conditions, and maintain water valve settings during power loss.

  • Publication number: 20140326803
    Abstract: A water gun clearing apparatus, particularly for application in self-serve car wash units, for use in clearing standing water from hoses, pipes and the water gun as well as preventing residual water moisture from building-up within the water gun. The water gun clearing apparatus comprises an air regulation system connectable to a source of pressurized air, and a timer. The air regulation system comprises a first air line branch configured to provide a continuous supply of pressurized air at a first flow rate, and a second air line branch configured to provide a supply of pressurized air at a second flow rate. Following use of the water gun by a user, the timer activates and provides pressurized air to the water gun at the second flow rate for a pre-determined time period in order to clear residual water from the water line and water gun.

  • Patent number: 8851397
    Abstract: Rotary bell cup atomizing apparatus is provided having a rotatable bell cup driven by a motor shaft dimensioned so as to provide an annular gap between the outer, rear surface of the cup and the shaft extending an effective distance axially adjacent the shaft. Solvent channels extend within the assembly circumventing the gap and discharge into the gap. During cleaning of the atomizer, solvent passes partially through the paint nozzle and partially through the solvent channels impinging directly upon the shaft, then migrating over the outer surface of the cup. The inner and outer surfaces of the bell cup and the motor shaft are simultaneously cleaned. A replaceable sleeve placed inside the cup adjacent the front surface thereof absorbs the force of paint impinging thereon. The cup may have at least one balancing indentation immediately adjacent the sleeve.

  • Publication number: 20140252121
    Abstract: A system, in certain embodiments, includes a spray device including a first liquid passage configured to flow a first liquid in a generally downstream direction toward a spray tip. The spray device also includes a second liquid passage configured to flow a second liquid in a generally upstream direction such that the second liquid impinges upon the first liquid at an outlet to the second liquid passage. The upstream direction is substantially opposite from the downstream direction.

  • Publication number: 20140239090
    Abstract: In the present invention, a cylinder chamber is provided in a main injector body having a nozzle that injects fuel. In the cylinder chamber, a command piston for driving a needle that opens and closes the nozzle is reciprocably received. A cleaning liquid supply pathway for supplying cleaning liquid and a cleaning liquid discharge pathway for discharging cleaning liquid are connected to the cylinder chamber. As a result, adhesive accretions in the cylinder chamber of the main injector body are discharged out of the cylinder chamber together with the cleaning liquid, and therefore it is possible to prevent a negative effect resulting from the adhesive accretions without using an additive or the like.
