  • Publication number: 20230069163
    Abstract: A multi-component fluid delivery system includes a heater system. The heater system includes an improved fluid preheating system based on a high conductivity fluid heat exchange manifold that is coupled to external heater elements (e.g., powered via electricity). These techniques can provide more surface area for heating fluid and is external to the fluid passages, making service or replacement much easier. These techniques can utilize etched foil or wire wound heater elements that operate at a lower internal temperature than cartridge heaters, and thus can be inherently more reliable.

  • Patent number: 11376618
    Abstract: A fluid delivery system includes a status indicator and control system comprising a processor. The processor is configured to receive a first signal indicative of a first status of operations of a spray application system. The processor is further configured to provide to an operator of a spray gun, via a display system, a visualization representative of the first status of operations, and techniques to control the fluid delivery system, wherein the spray application system is configured to deliver at least one fluid to the spray gun during operations.

  • Patent number: 11047378
    Abstract: A system includes a fluid pump and a first pressure sensor disposed on or near an inlet of the fluid pump. The system further includes a second pressure sensor disposed on or near an outlet of the fluid pump and a control system. The control system includes a processor configured to receive a first signal from the first pressure sensor. The processor is further configured to receive a second signal from the second pressure sensor, and to derive a pump slip measure based on the first signal and the second signal.

  • Patent number: 11027304
    Abstract: A multi-component fluid delivery system includes a first fluid pump and a second fluid pump. The first and the second fluid pumps are not mechanically coupled to each other. The multi-component fluid delivery system further includes a control system comprising a processor configured to derive a slip ratio for the first fluid pump and the second fluid pump. The processor is additionally configured to apply a master-slave motor control to deliver a specified fluid ratio via the first and the second fluid pumps based on the slip ratio.

  • Patent number: 11022987
    Abstract: A fluid delivery system includes a first pressure sensor disposed on or near a spray gun and configured to monitor a first fluid, and a second pressure sensor disposed on or near the spray gun and configured to monitor a second fluid. The fluid delivery system further includes control system comprising a processor configured to receive a first signal from the first pressure sensor and to receive a second signal from the second pressure sensor. The processor is further configured to derive a pressure difference between the first and the second pressure sensor representative of a fluid pressure difference between the first fluid and the second fluid and to control one or more pumps to obtain a desired pressure difference.

  • Patent number: 5879003
    Abstract: A sheet feed apparatus for an imaging device. The apparatus includes a drive roller, plurality of sheets of photosensitive material, a photographically inert liner having upper and lower surfaces and a container for storing the sheets of photosensitive material. Proper feeding of the sheets of material and a stable location of the liner are ensured by appropriate coefficients of friction between the respective components. The top surface (19b) of the liner (19) to the bottom surface (18B) of the sheets (18) has a first coefficient of friction and the bottom of one sheet (18) to the top of another sheet (18) has a second coefficient of friction, the second coefficient friction being less than the first coefficient of friction, whereby multiple feeds of the sheets are reduced.
