A spray coating apparatus that applies a coating material onto outer surfaces of glass objects includes a coating material source that includes a coating material. A spray nozzle assembly includes a spray nozzle fluidly connected to the coating material source. The spray nozzle is arranged and configured to direct the coating material in a first direction toward the glass object and provide an overspray amount of the coating material by the glass object such that the overspray amount bypasses a non-line of sight area of the glass object. A turn nozzle assembly includes a turn nozzle fluidly connected to a pressurized gas source. The turn nozzle is arranged and configured to direct pressurized gas in a second direction different than the first direction toward the non-line of sight area of the glass package to redirect the coating material onto the non-line of sight area.

Disclosed herein are methods and systems for automatically spraying a glaze solution onto a dental prosthesis. The automated spray glazing system includes: a first spray gun; a controller, and a gripper configured to hold the dental prosthesis and to rotate the dental prosthesis about an axis. The controller is configured to rotate the gripper and spray a glaze solution from the first spray gun using a glazing profile based at least in part on a type of the dental prosthesis. The glazing profile is selected such that a cross-sectional thickness of a resulting-glazed material of the dental prosthesis has an average thickness range between 15 to 63 μm and a standard deviation of less than 6 μm when measured at locations in an upper half of the dental prosthesis.

A sprayer for spraying fluid includes a pump, a motor that drives the pump, a drive cycle indicator, a wireless module configured to send and receive information, and control circuitry. The drive cycle indicator outputs an indication of cycle status of the pump. The control circuitry is configured to receive the plurality of cycle status indications of the pump, determine a plurality of output values representing paint spray fluid output volume over a plurality of time windows based on the plurality of cycle status indications of the pump, store the plurality of output values in memory, and cause the wireless module to transmit one or more of the stored plurality of output values externally from the sprayer.

A high-pressure valve for a spray nozzle. The high-pressure valve includes a valve inlet, a valve outlet to which the spray nozzle is attachable, a fluid connection which connects the valve inlet to the valve outlet, a movable piston, a tappet which is arranged in the fluid connection, and a flushing apparatus which flushes the high-pressure valve and/or the spray nozzle with a flushing liquid. The tappet moves between a closed position and an open position via the movable piston. A spray liquid reaches the valve outlet and/or the spray nozzle from the valve inlet via the fluid connection when the tappet is in the open position.

Handheld gas spray systems for mixing and dispensing multi-component compositions.

A device for cleaning and drying a spraying unit, the device containing: a top end and a bottom end; the top and bottom end connected to each other by a housing; the housing having an opening proximate the top end, for receiving at least a portion of a spraying unit; a first liner within the housing; a second liner within the first liner; the first liner fitting within the housing forming a space between an outside wall of the first liner and an inside wall of the housing; the second liner fitting within the first liner forming a space between an outside wall of the second liner and an inside wall of the first liner; the opening further containing an open cap, proximate the top end; the device having at least one vacuum air supply influent port, at least one drying air supply influent port and at least one solvent supply influent port.

Exemplary illustrations of a fluid valve, e.g., a return valve for returning residual paint, rinsing agent, and compressed air from a paint line when changing color in a painting system, are disclosed. An exemplary fluid valve may be adjusted between an open position, in which the fluid valve is at least partially open, e.g., for rinsing a paint line with a rinsing agent and for pressurizing the paint line with a new color for the color change, and a closed position, in which the fluid valve is closed, e.g., for applying the new color after the color change. An exemplary fluid valve may switch to the closed position, upon actuation by the medium thereof, e.g., medium flowing through or present in the valve. In another example, a fluid valve may close depending on the fluid present at the input side.
