Abstract: A molding lens with indentations for measuring eccentricity and a method for measuring eccentricity thereof are disclosed. At least one indentation concentric with an optical surface is respectively disposed on a front plane and a rear plane of the molding lens on area outside the optical surface while the indentation is observed by means of a measuring microscope. Moreover, the eccentricity of the molding lens is detected by eccentricity test function of the measuring microscope and the eccentric direction is defined so as to modify the lens mould and replace conventional eccentricity test that uses a transmission eccentric scale indicator in combination with a jig. Thus the cost of test equipment is reduced, test procedure is simplified and efficiency of mould modification is improved. Therefore, it's more convenient to manage manufacturing of the lens.

Abstract: A redox flow battery 1 has a stack of individual cells, shown diagrammatically as a single cell, with anolyte and catholyte compartments divided from each other by an ionically selective and conductive separator and having respective electrodes. The battery has anolyte and catholyte tanks, with respective pumps and a pipework. In use, the pumps circulate the electrolytes to and from the tanks, to the compartments and back to the tanks. Electricity flows to a load. The electrolyte lines are provided with tappings via which fresh electrolyte can be added and further tappings via which spent electrolyte can be withdrawn, the respective tappings being for anolyte and catholyte. On recharging, typically via a coupling for lines to all the tappings, a remote pump pumps fresh anolyte and fresh catholyte from remote storages and draws spent electrolyte to other remote storages.

Sublengths of inner conductor are exposed along the line, with adjacent sublengths being separated by shielded sublengths. In one embodiment the apparatus is excited by a signal and inserted into the materials to a predetermined depth. Signal attenuation is measured. The interface between strata is identified based upon signal attenuation. In another embodiment the apparatus is excited by a signal and progressively inserted into the materials. Apparatus position is tracked and t-he attenuation of the signal is monitored as a function of insertion distance to detect ranges having a substantial rate of change of attenuation and ranges having substantially no change of attenuation. The interface is identified based upon differences in the rate of change in attenuation.
