  • Publication number: 20150083238
    Abstract: An automatic protection device for an inlet valve or drain valve includes an inlet, an outlet, an on-off component, a control circuit, a control component, a water level inductor of the water tank and a water level inductor of the toilet. The water level inductor of the water tank and the water level inductor of the toilet are respectively connected to the control circuit, the control circuit drives the control component, the control component is connected to the on-off component to control the on-off component to open or close, thus connecting or disconnecting the inlet and the outlet. The automatic protection device will sound an alarm and automatically cut off the water supply when the drain valve fails to discharge, or when the toilet is plugged up and is unable to drain water.

  • Patent number: 8792386
    Abstract: An attribute propagation method and a switch system based on a fiber channel network are disclosed. According to the present invention, after an attribute is registered on one of its ports, each switch can automatically use its port on the other side to propagate this attribute, and a next adjacent switch can register this attribute on its port on the same side, so that ports on one side of all switches can have this attribute registered automatically. Hereafter, after the attribute is registered its port on the other side, each switch can automatically use its port on said one side that has been registered to propagate this attribute reversely and a next adjacent can register this attribute on its port on the other side, so that ports on the other side of all switches can automatically have this attribute registered. In this way, there is no need to manually configure each port.

  • Patent number: 6974291
    Abstract: A quick coupling nut includes a body having a bore therethrough and adjacent side holes. A pair of threaded members are disposed in the bore and moveable in a radial direction of the bore and a cap having a bore therethrough, coaxial with the body bore, includes depending guides which are received by the guide holes for enabling axial movement between the cap and the body. Actuators depending from the cap engage the threaded members in order to urge the threaded members radially inward to engage a threaded bolt shank, extending through the cap and body bores, as the cap is moved axially toward the body. This threaded engagements enables tightening of the quick coupling cap by rotation about the threaded bolt shank.
