A cooling system is provided includes a target material and a plenum or header structure. A plurality of nozzle structures is coupled to the plenum or header structure that provides a uniform flow stream from each nozzle structure. The nozzle structure are angled away from the center of the target material as well as being angled in the direction of travel of the target material so as to improve cooling uniformity by providing independent fluid paths from each of the nozzle structures to the edge of the target material reducing the interaction of fluid streams from adjacent nozzle structures.

In one aspect, the present disclosure relates to a bowling lane conditioning machine. The bowling lane conditioning machine has a drive mechanism for moving the conditioning machine along a bowling lane, a fluid storage tank that stores a conditioning fluid; a dispensing assembly for dispensing the conditioning fluid about the bowling lane; and a pump for moving the conditioning fluid along a flow path between the at least one fluid storage tank and the dispensing assembly. The conditioning machine further includes contaminant sensing assembly positioned along the flow path of the conditioning fluid for detection of one or more contaminants in the conditioning fluid. Other aspects also are described.

Systems and methods for applying a liquid coating to a substrate are disclosed herein. One exemplary method includes calibrating flow rate of a material through a coating system. A target flow rate for the material through a spray nozzle is received, a first operating pressure of the coating system based upon the target flow rate is calculated, and the material is ejected onto a least part of a surface with the material flowing through the spray nozzle at the first operating pressure of the coating system. If it is determined that a difference between an operating flow rate and the target flow rate is outside of a predetermined control range, the operating pressure is adjusted to a second operating pressure and at least part of the substrate is sprayed with the material flowing through the spray nozzle at the second operating pressure of the coating system.

An electric solenoid valve, methods for operating and/or actuating the solenoid valve, valve system diagnostics, and applications for use are described. The valve may be designed to actuate in a manner so as to control liquid flow into and/or through a device, such as a spray nozzle. By altering the characteristics of the electrical signal transmitted to the solenoid valve, the instantaneous pressure across the valve and duration of fluid flow through the valve can be controlled with a single actuator. Controlled cyclic durations of flow may be implemented to regulate the exact timing of flow through the valve. Alternatively, cyclic durations may occur with a pulse-width modulation technique in which the duty cycle regulates average flow rate through the valve.

A control method for a two-component spray system having first and second pumps for separate fluid components includes registering a target spray pressure, registering a material-specific pressure factor margin, sensing an output pressure of the second pump, and identifying a failure condition in the event that the sensed output pressure remains further than the pressure factor margin from the target spray pressure for at least a threshold time.

A handheld shower head includes a shower head body, a water inlet assembly and a water outlet assembly mounted on the shower head body. The water inlet assembly includes a water inlet body and a flow control device. The flow control device includes a gasket, a return spring, a control valve shaft, and a control button. The control valve shaft passes through the flow control chamber of the water inlet body. A lower portion of the control valve shaft is connected with the gasket. The control button is connected with an upper portion of the control valve shaft. The handheld shower head can control the flow rate of water discharge and is user-friendly.

A shower head, illustratively for a sanitary shower, including a shower head housing, a fluid inlet into the shower head housing, a shower jet outlet out of the shower head housing, a fluid duct within the shower head housing from the fluid inlet to the shower jet outlet, and an overpressure valve pressure-coupled to the fluid duct, including a movable valve body which, in case of an overpressure in the fluid duct, moves from a normal position to an overpressure position. The valve body is illustratively configured to be self-retaining in the overpressure position and returnable to the normal position by user operation, and/or the valve body acts position-dependent on a passage cross-section of the fluid duct, wherein the valve body reduces the passage cross-section in the overpressure position relative to the normal position.

Techniques herein include systems and methods for dispensing liquids on a substrate with real-time coverage control and removal control. Techniques also encompass quality control of dispense systems. Systems and methods enable visual examination of liquids progressing on a surface of a substrate. This includes capturing and/or examining stroboscopic images of movement of a given liquid on a working surface of a substrate, and then generating feedback data for modifying a corresponding dispense. Dispenses can be modified by increasing/decreasing a dispense rate and increasing/decreasing a rotational velocity of a substrate. Feedback can be generated by automated and/or manual analysis of real time progression as well as post-process analysis of collections of images.
