摘要： A maintenance-free battery having improved float current (i.e.-current draw) characteristics is provided by adding elemental zinc, or a zinc affording compound such as zinc sulfate to the battery in amounts sufficient to decrease the float current that would otherwise occur during voltage regulated overcharge. Rather than utilizing zinc alone, a mixture of zinc and cadmium may likewise be employed.

摘要： A mold for forming objects such as battery grids includes a cavity having a titanium layer with an adherent titanium oxide layer integrally formed thereon. The oxide layer is formed by heating the titanium layer under controlled oxidizing conditions to provide an oxide layer of a specified thickness which is tenaciously adherent to the unoxidized titanium.

摘要： A coating for the internal cavity of a mold for forming objects such as battery grids and the like including a perfluorocarbon film (e.g., - tetrafluoroethylene) having dispersed therein heatinsulating particles (e.g., - talc). The thickness of the film and the size and amount of the heat-insulating particles are maintained within defined limits to allow formation of complete grids with easy release from the mold.

摘要： 1474802 Lead-acid battery GOULD Inc 8 July 1974 [9 July 1973 (2)] 30217/74 Heading H1B Crystal growth between the formed negative and positive plates of a dry-charged lead-acid battery which may occur before activation of the battery by the addition of electolyte thereto, is prevented by treating the plates with a metal sulphate soluble in sulphuric acid or water. The preferred sulphate is of sodium, other suitable sulphates being of K, Li, Mg, Ca, Zn, and Al; additionally, the sulphates of Be, Ce, In, La, Sn, Tl, Zr and Rb, may be used. In one method of making the battery the metal sulphate is added to the formation electrolyte, viz. H 2 SO 4 solution of S.G. in the range 1À020- 1À100, the metal sulphate being present in an amount of about 2 per cent by wt. The electrolyte is subsequently removed by inverting the battery. In a preferred method, the formation electrolyte does not contain the metal sulphate and after removal of this electrolyte the battery is filled with a H 2 SO 4 rinse solution of S.G. in the range 1À200-1À400, this solution containing 0À05-5 per cent by wt. of the metal sulphate. The plates and separation are soaked for about 10 minutes in the rinse solution which may be stirred and the solution is then removed by inverting the battery. In another method the metal sulphate is dissolved in water in an amount 0À05-5 per cent by wt. and the battery is filled with this solution either after draining the formation electrolyte or after draining the rinse solution, the water being subsequently drained from the battery. Whatever method is used for adding the metal sulphate the battery is subsequently sealed in a manner such that gas-pressure build-up within the battery may be vented and slight ingress of air into the battery is permitted. The very small amount of oxygen permitted to enter the battery during its shelflife tends to equalize the self-discharge of the positive and negative plates and reduces the tendency for the initial battery performance to be positive plate limited. The vent aperture may be circular in shape and have a diameter of 0À0005-0À006 inch. A venting arrangment, Figs. 4, 5, comprises two groups 35 of three vent caps each having a main body 36 formed with normal labyrinth passages (not shown) for breathing of the battery after it has been made operational. During the battery shelf-life the cell apertures 34 in the battery lid 33 are sealed by plugs 38 each having a small vent aperture 40 (referred to above) and the caps 35 are retained by flanges 42 cooperating with upstanding portions 43 on the seal plugs 38. The battery is brought into operation by removing the plugs 38 by tabs 41, filling with electrolyte, and engaging the cap flanges 42 in the apertures 34. In a modified venting arrangement (Figs. 7-9, not shown) the small vent aperture is replaced by a small groove formed in the outer surface of the side wall of the seal plug.

摘要： 1439888 Lead base alloy GOULD Inc 18 Sept 1974 [3 Oct 1973] 40610/74 Heading C7A [Also in Division H1] A cast lead-base alloy containing 0À06-0À1% Ca 0À1 -0À4% Sn Balance Pb and impurities is suitable for the manufacture of grids for lead-acid batteries or storage cells or sealed, maintenance-free cells. The presence of a maximum of 0À4% Su lowers the dross formation at temperatures up to 800‹F and improves the active material retention characteristics of the cast grid by resisting corrosive degradation.
