Abstract: Batteries are moved along a first roller type conveyor to a leak testing station, above which is located an assembly having a plurality of nozzles matable over battery cell inlets. A first set of alternate cells is supplied with air at a given pressure, and metering means notes pressure change. Thereupon, the remaining alternate cells receive the same treatment. If the cells do not leak, the battery advances from the testing station along the roller conveyor. If a leak is detected, a push bar connected to a cable system below the rollers ejects the battery transversely from the testing station along to a second conveyor, thereby isolating leaky batteries either for removal or further testing to locate more precisely the leak.

Abstract: Burners are provided above a battery for burning together high profile bushings inserted in the battery cover and lead posts extending generally upward from the battery. The high profile bushings surround the battery posts. In order to insure a complete weld throughout the entire lead bushing and post, the burners are supported in such a way as to orbit between the bushing and post. The burners orbit within this support in close proximity to the heat of the burner flame. To provide heat insulation from the tips of the burner, a heat shield is provided intermediate the battery post and bushings and the rotation mechanism of the burners themselves. Means for automatic ignition of the burners are provided as well as molds for the battery posts and bushings. The molds are provided with a water cooling capability and a separating means which surrounds the molds and holds the battery motionless as the molds are retracted after the burning has taken place.

Abstract: An integral and homogeneous connection between a terminal and a battery lug is accomplished without the requirement of specially shaped projections on either of the surfaces of the terminal or lug. Insulation is disposed between the lug and terminal and a portion of the overlapping area of the lug is pressed through an opening in the insulation means to make contact over a relatively small area with the terminal. Welding jaws are used to press the lug and terminal together and a current is provided by the welding jaws to heat up the area of contact so that the lead begins to melt in the opening. Since the lug and terminal are continuously squeezed together by the welding jaws, more cold lead is introduced into the opening until the entire opening is filled with molten lead from the lug and terminal.

Abstract: Containers, such as batteries, battery cases and the like, are moved along a first conveyor to a leak testing station, above which is located an assembly having means matable over the openings in the top of the container. The container is supplied with air at a given pressure, and metering means notes pressure change. If the container does not leak, the container advances from the testing station along the conveyor. If a leak is detected, a reject means ejects the container transversely from the testing station along a second conveyor, thereby isolating leaky containers for further processing.

This coupling means is designed to quickly and positively engage the cooking grill when inserted from a direction approximately perpendicular to the cooking surface.

Abstract: A novel method of producing storage battery lead alloy parts is provided comprising the steps of (a) providing a grid mold having a mold substrate consisting essentially of aluminum, (b) hard surface anodizing at least a portion of said mold substrate to produce molding surface thereon, (c) introducing molten lead alloy into such mold against said molding surface and (d) allowing said lead alloy to cool to form said storage battery grid. Other steps which may be included as a novel method of the present invention including texturing the mold substrate prior to the hard surface anodizing step to form a discontinuous surface thereon, which texturing step may be accomplished by peening said substrate with shot, blasting said substrate with glass beads, or blasting said substrate with sand.

Abstract: A vented battery cap is provided which is adapted to engage at least one of a plurality of fill holes in an automotive storage battery or similar lead acid battery and which has pressure release means for venting the combustible gases produced within that storage battery under conditions such as overcharge conditions into the atmosphere, said pressure release means comprising a plurality of extremely narrow slits having widths in the order of 0.003 to 0.005 of an inch. The remainder of the battery cap is tightly sealed to prevent any extraneous leaks of battery gases received from the automotive battery from leaking into the atmosphere. The slits are so constructed to facilitate the safe expulsion of any volume of gas normally produced by an automotive storage battery, while virtually eliminating the likelihood that ignition of gases within the atmosphere will result in explosive consequences either within the battery cap or within the battery itself.

Abstract: Material is fed into a revolving drum which has an interior configuration, preferably in the form of a helical blade, to convey the material at a controlled rate through the drum. A low temperature gas, such as nitrogen, is introduced into the drum downstream when viewed in the direction of travel of the material, in a liquid state at a controlled rate through a spray nozzle system, thereby continuously exposing the material to the cooling effect of the gas. A portion of the gas is recirculated from the upstream end to the downstream end of the drum. The material is pre-cooled in the upstream portion of the drum. After exiting from the drum, the material may be crushed or impacted and separated.
