670,048. Batteries. BABCOCK & WILCOX CO. Aug. 12, 1949 [March 31, 1949], No. 21031/49. Class 53. [Also in Group XIII] A storage battery is provided with a device for condensing the electrolyte carried over in the gases avolved from the battery during charging and returning the condensed electrolyte to the battery. Figs. 2 and 3 show the device in part sectional elevation and plan. A chamber 18 fits into the vent opening 14 of the battery 10 and is provided with an internal compartment comprising side walls 24, 26, a perforated wall 28 and a base 22 formed with a flange 29 which abuts against the side wall of the chamber 18. A tube 36 leads from the base of the compartment and terminates below the level of the electrolyte in the battery. The side of the compartment opposite the side 28 is open. Gas from the battery passes through the open side into the compartment and out through an equalizing chamber 35 and an opening 40 which is connected to a fan for drawing the gases from the battery. An air inlet is provided in the top of the battery. Within the compartment are rows of airfoil separator elements 30 arranged at an angle to the fluid flow as shown in Fig. 3. Liquid separated from the gases collects on the elements 30 and runs down them into the space 34 from which it drains back into the battery through the tube 36. The elements 30 depend from a plate 48 above which is a cover 50 secured to the chamber 18. Specification 635,241, [Group XIII] is referred to. |
