Abstract: A method for correcting birefringence in a fiber optic coupler comprising measuring the intrinsic birefringent retardation, fast axis orientation and rotation of separate paths through the coupler and adding lumped birefringent elements to the ports of the coupler in a fashion to compensate for the intrinsic birefringence.

Abstract: A flushing device controllable for discharging a desired amount of water after use of a toilet is provided with a cylinder supported within the tank, a piston slidable in the cylinder and divides the inner space thereof into an upper chamber and a lower chamber with variable volumes, on the piston there are provided with through holes for communicating these two chambers, and a flexible baffle member is attached to the bottom surface of the piston and capable of admitting the water to flow from the upper chamber into the lower chamber. A piston rod is connected to the piston and terminates in a stopper positioned in alignment with the flushing pipe, by means of a compression spring mounted with respect to the piston rod between the cylinder and the stopper, the stopper is normally biassed against the flushing pipe until a pull of the piston which forces the stopper moved away from the discharging pipe against the biassing of the spring and so that initiates the flushing, a lower chamber filled with water having a volume corresponding to the piston displacement is caused in the movement of the piston, the piston and the stopper is therefore prevented from lowering until the compression predominates over the buoyance of water received in the lower chamber.

Abstract translation: 在使用马桶之后可控制排出所需量的水的冲洗装置设置有支撑在罐内的缸体，可在缸体中滑动的活塞，并将其内部空间分成具有可变体积的上室和下室， 在活塞上设置有用于连通这两个室的通孔，并且柔性挡板构件附接到活塞的底表面并且能够允许水从上室流入下室。 活塞杆连接到活塞并终止于与冲洗管对准的止动件中，通过相对于活塞杆安装在气缸和止动件之间的压缩弹簧，止动件通常偏压在冲洗管 直到活塞的拉力迫使止动件从排放管移开而不受弹簧的偏压影响，从而启动冲洗，在充满水的下部腔体中具有与活塞位移相对应的体积， 因此，活塞和止动器因此被防止下降，直到压缩超过在下腔室中接收的水的浮力。
