Filed: 1967-02-07
Abstract: A moving metallic strip 10 e.g. of steel is continuously electro-plated on one side e.g. with Zn by guiding it under tension about a major portion of the periphery of a rotating member, e.g. a drum 12 mounted on a shaft 13, submerged in an electrolyte 16 contained in a tank 14, using a pair of guide rolls 15 arranged either side of a vertical plane through the axis of the rotating member, so that the strip is maintained in contact with the periphery during passage through the electrolyte spaced from and co-extensive with an arcuate anode 17, the electrolyte being supplied e.g. via inlet 18 to the bottom of the space S between the anode and the strip. A single or dual Ni contact ring (22, Fig. 2) is provided intermediate insulating sealing bands (23) on the periphery. For electro-plating both sides, two successive tanks with rotating members are employed, the strip being coated in the second stage 21 either with the same material e.g. Zn or with a different material e.g. Cr. The anode may be of Pb with 0À5% Ag or 7% Sb. The electrolyte may be recirculated through the tank (Figs. 8 and 9).

Title: Reactor-turbine control for low steam pressure operation in a pressurized water reactor
IPC: G21D3/00
Filed: 1974-11-27
Abstract: A control system for a pressurized water reactor power plant. The control system comprises temperature sensing means having flow interruption means connected thereto. The temperature sensing means monitors the temperature levels within the reactor element and sends a predetermined signal to the flow interruption means upon a predetermined change in reactor temperature. The flow interruption means is disposed within an associated steam turbine loop including a steam generator element which transforms secondary water into steam to act as motive fluid within the turbine loop. The flow interruption means initiate one or more flow interruption activities which either produce an increased temperature differential between the secondary water and the steam produced therefrom or increase the rate of flow of steam within the associated steam turbine loop. Utilization of the control system permits extensive operation of the reactor element past the end of the normal fuel cycle life. In addition, the control system provides improved reactor load follow capability.
