TL;DR: In this article, a flow rate and droplet size control system for a spray system including a spray liquid source, a pump, a spray line and a nozzle assembly is presented.
Abstract: A flow rate and droplet size control system for a spray system including a spray liquid source, a pump, a spray liquid line and a nozzle assembly. The control system includes a setpoint conversion subroutine for independently controlling the flow rate and volume median droplet size setpoints. The control system also includes performance envelopes for various nozzle tips. An independent flow rate and droplet size control method is provided for use with the control system. A position-responsive control system receives information pertaining to the boundaries of spray zones and spray conditions, such as application rates and volume median droplet diameters associated with the spray zones. The position-responsive control system monitors the position of a spray vehicle, which can comprise a ground vehicle or an aircraft. The position-based control system changes the spray system operating conditions in response to the sprayer vehicle position. A position-based method of controlling the spray system utilizes the position-based control system.

TL;DR: In this paper, a holder device may be attached to a water outlet tube which is extended from a wall, without drilling holes in the wall, and includes a housing having an inlet attached to the water outlet, and two or more outlet ports for coupling to a shower head and a sprayer nozzle, a base having a spring-biased latch for clamping the pipe to the base, a seat slidably attached onto the pipe for adjustably and removeably supporting the sprayer.
Abstract: A holder device may be attached to a water outlet tube which is extended from a wall, without drilling holes in the wall, and includes a housing having an inlet attached to the water outlet tube, and two or more outlet ports for coupling to a shower head and a sprayer nozzle, a base having a spring-biased latch for clamping the pipe to the base, a seat slidably attached onto the pipe for adjustably and removeably supporting the sprayer nozzle. The housing includes a casing having a chamber for receiving a valve stem, and a spring-biased valve member received in the valve stem to control the water to flow out through the outlet ports of the housing, and a knob secured to the valve stem to rotate the valve stem relative to the casing and the housing.
