Abstract: A timed control valve is of the type that is installed in a fluid line upstream from a regular valve and capable of being physically oriented an any direction in the fluid line. The timed control valve is capable of sensing at least the normal flow of fluid when the regular valve is opened, stopping the normal flow at an end of a first predetermined period of time beginning with an initial sensing of the normal flow; and then allowing the normal flow at an end of a second predetermined period of time beginning with an initial stopping of the normal flow. Various embodiments of the timed control valve include different sensing and timing device for regulating the overall amount of the fluid that can be used and can even be configured to protect against a major loss of fluid if there is a rupture or failure of the fluid line down stream of the timed control valve. The invention also includes the method of doing the same.

Abstract: A capping apparatus and a magnetic coupling assembly therefor comprises a capping head for applying a cap, a drive mechanism for driving the capping head, and a separable magnetic coupling for selectively coupling the capping head to the drive mechanism. The separable coupling is operable to selectively drive the capping head at an initial rotational speed and for selectively de-coupling the capping head from the drive mechanism while the capping head is rotating. This allows the capping head to be moved toward a container to place the cap on the container while preventing the drive mechanism from continuing to drive the capping head as the cap is placed on the container.
