Abstract: An apparatus and method of analyzing phases of a multi-phase mixture allows an analysis of a mixture that has great turbidity or is opaque. An emission device emits electromagnetic radiation in a direction of a measurement cell. The electromagnetic radiation is back scattered by the mixture and is detected by a primary detection device. A secondary detection device may detect electromagnetic radiation that is transmitted but is not back scattered by the mixture. A moving device displaces the primary detection device in order to carry out a plurality of detections at a predetermined step over the length of the measurement cell. The scanning of the cell allows one to obtain a cycle of measurements that produces a phase profile of the mixture.

Abstract: A front panel for circuit boards e.g. in a telecommunications exchange which plug into connectors attached to a bin, the boards sliding in guides in said bin. Such circuit boards can be difficult to remove from the bin because of multiple contacts in the connectors. The panel is intended to facilitate extraction of its board and comprises a bar of insulative material acting as a stiffener for the board, fitting over the front edge thereof, and an extractor lever articulated to the base of the stiffener bar.
