Abstract: A method of conserving a facility delivered to a machine during the machine's idle mode is herein described. In one embodiment, the method is directed to a method for conserving coolant water delivery to a semiconductor wafer grinding machine. The system monitors the status of the grinder to determine whether the grinder is active or idle. After the system determines the grinder has entered idle mode, the system reduces the flow of water to the machine. In one embodiment, the flow is simply reduced while, in another embodiment, the flow is terminated. A delay circuit in the system may delay the reduction of the flow rate until some point after entering idle mode. Periodically throughout the idle mode, the system increases the flow of coolant water to the grinder to ensure the temperature of all grinder components remains consistent. The duty cycle of the coolant flow may be adjusted to optimize water conservation and machine readiness.

Abstract: A system and method for controlling the flow of water through a water supply line into a building. The system has a valve that connects to the water supply line of the building. The system also includes a flow meter that connects to the water supply line, wherein the flow meter produces a water flow signal indicative of the volume of water flowing through the water supply line. A systems controller is provided that is connected to both the valve and the flow meter. The systems controller is configurable between a first operations mode and a second operations mode. The systems controller reads the water flow signal from the flow meter and closes the valve at a first flow rate when it is in its first operations mode. Similarly, the systems controller closes the valve at a second flow rate when it is in its second operations mode. When the flow meter detects an excessive volume flow, the systems controller only closes the valve if the excessive flow persists beyond a predetermined period of time.

Abstract: This invention pertains to an air compressor having a cylinder head with an air supply passage communicating with a discharge hole. First and second exhaust passages are arranged in parallel between the air supply passage and an exhaust port. A pilot-operated switching valve is located at an intermediate position in the first exhaust passage. A solenoid-operated exhaust valve is located at an intermediate position in the second exhaust passage. The solenoid-operated exhaust valve is selectively opened or closed by an externally supplied electric current, thereby controlling a pilot pressure applied to a valving element of the pilot-operated switching valve. The valving element is rested on or separated from a valve seat by the pilot pressure. The compressed air discharge speed can be increased without increasing the size of the cylinder head, and vehicle height adjustment, for example, can be made in a reduced period of time.

Abstract: An automatic fluid shut-off device for interrupting fluid flow through a fluid supply path in a fluid delivery system. The automatic fluid shut-off device includes: a fluid flow sensor structured and disposed for monitoring fluid flow in a fluid supply path; a control panel housing, a central processing unit, and including a visual display panel, programming buttons, and indicator lights; and either a solenoid actuated fluid shut-off valve or relay that interrupts power to a fluid pump. The fluid flow sensor monitors fluid flow in the fluid supply path and outputs the fluid flow data to the central processing unit. The central processing unit compares the measured fluid flow value with the value preprogrammed for the particular operating conditions or for the particular active zone in a multi-zone fluid delivery system.

Abstract: A water recirculation system is disclosed for moving water from a hot water tap to a cold water tap. The recirculation system includes a water manifold that houses a pump, solenoid, check valve and temperature switch. Water is moved between these components within the water manifold so that external piping is unnecessary.

Abstract: There is described a programmable electronic timer for the control of a solenoid valve, particularly for watering systems. The timer comprises a start button, a stop button and a programmable processing unit. The latter is preset to determine, as a consequence to the operation on said start button, the opening of the controlled solenoid valve and the starting of a time count and, as a consequence to the operation on said stop button, the closing of the solenoid valve and the end of said time count with memorisation of the counted time for the subsequent automatic control of the opening and closing of the solenoid valve in the next days at the same time and for the same watering length of time.
