Abstract: A faceplate of a cathode ray tube is shown wherein a cathodoluminescent phosphor material 1 is deposited on glass faceplate 2. A metal nitride metal absorbing inhomogeneous film 3, where the metal is aluminum or silicon, is deposited on the back side of the phosphor material 1. To avoid unwanted reflections at the interface between the glass 2 and the phosphor 1, a homogeneous film 4 is optionally deposited on glass plate 2 prior to deposition of the phosphor film 1. Additionally, an anti-reflection coating 5 may also be optionally applied to the exterior of the glass plate 2 to eliminate reflection that would otherwise occur at the air-glass interface.

Abstract: An electrically rechargeable battery comprising an inert cathode, a zinc anode and an aqueous alkaline electrolyte, for example, NaOH, in which said anode and cathode are immersed. The alkaline electrolyte in the vicinity of the cathode contains an alkali metal ferricyanide salt, such as K.sub.3 Fe(CN).sub.6 or Na.sub.3 Fe(CN).sub.6. Optionally, a mechanical separator is utilized between the anode and cathode to prevent gross mixing of the saturated electrolyte at the cathode with the electrolyte in the vicinity of the anode. Preferably, the separator is of the ion exchange type. During electrical discharge, at the anode and cathode, the battery produces soluble reaction products which are transported in the electrolyte to respective external storage tanks which increase battery capacity. During the charge cycle, the reverse conditions occur.
