IPC: B01J49/00
Filed: 1997-02-18
Abstract: A water softening system (10) is provided in which a determination is made whether the slow rinse cycle of a regeneration has been completed or is abnormal. A  reference cell (Rr) and a spaced sensing cell (Rs) are provided in a water tank (12).  Reference cell (Rr) and spaced sensing cell (Rs) carried by probe (27) are connected via lines (30, 31 and 32) to pins (1, 2 and 3) of plug (34). The impedance difference of the solution between the reference cell (Rr) and the sensor cell (Rs) is sensed. If the impedance difference is a first state, then after a predetermined period of time a determination is made if the impedance difference is a second state. If the impedance difference is a second state, then after a predetermined period of time a determination is made if the impedance difference is a third state, this indicates that the sodium ion concentration is uniformly reduced in the zone between the reference cell (Rr) and the sensing cell (Rs) and that the slow rinse cycle has been completed.

Patent CA-2225737-A1 (CA)
Inventor: CARPENTER JAMES B
IPC: G02B6/38
Filed: 1996-06-05
Abstract: A device for interconnecting the bare ends of two or more optical fibers (18, 20) uses a common receptacle (12) having a fiber clamping element (66) therein and camming surfaces (70, 72) for actuating the element (66), and at least one plug having a camming finger (74, 76) for engaging one of the camming surfaces (70, 72). The camming surfaces (70, 72) are located such that, when only one of the camming surfaces (70, 72) is actuated, the clamping element (66) rocks to a side of the pocket opposite the one camming surface (70, 72) and remains in the open state, but when both of the camming surfaces (70, 72) are actuated, the clamping element (66) is forced to the closed state. The plug includes a fiber protector (23) free to slide within the plug housing (14, 16), substantially enclosing the bare end of the fiber (18, 20) when the plug housing (14, 16) is removed from the receptacle (12), but retracting when the plug housing (14, 16) is inserted into the receptacle (12) to direct the bare end of the fiber (18, 20) toward said guide tube (64). A fiber collet (26) biases the terminal end of the fiber (18, 20) toward the forward end of the plug to place a preload condition on the bare end of the fiber (18, 20). The connector (10) is particularly suited for cleave-and-bevel installations. The receptacle (12) preferably uses a novel clamping element (90) having two plate members (92, 94) with fiber-contacting surfaces, at least one of said fibercontacting surfaces having a fiber-receiving groove (108). Edges (96, 98) of the plates (92, 94) are aligned and held together with a split tube spring (112). At least one of the plate members (92, 94) is provided with a wirereceiving groove (100, 102) and a wire (114) therein which acts as a fulcrum to allow the plates (92, 94) to pivot along an axis defined by the wire (114). The split tube (112) spring provides a precisely controlled load along the edges (96, 98) of the plates (92, 94), allowing the opposite ends to be clamped together (within the guide tube (64)) by a force sufficient to overcome the controlled load of the split tube spring (112).
