Method and apparatus are disclosed for the pasting of foraminous battery plate substrates with viscous, thixotropic pastes using an extrusion type bifurcated nozzle.

Battery plate pasting method and apparatus

Circuitry is provided for automatically selectively switching a load from a primary power source to a secondary power source, and back again, including switch means connected between the primary and secondary power sources, and control circuit means which controls opening and closing of the switch according to the sensed voltage level of the primary source. Once the secondary power source has been switched on, at such time as its voltage level drops below a predetermined level the switch can be adapted to automatically disconnect the secondary power source (e.g., battery) from the load.

Multiple power source automatic switching circuitry

A through-the-partition connector particularly for lead-acid cells or batteries is disclosed in which a stud insert of relatively low electrical resistivity is embedded within a deformable lead shroud post which is tightly seated within the partition. In one aspect, the lead shroud and the partition seat are configured with inclined ramp portions, e.g., frustroconical in shape, and an interference fit is formed therebetween for an improved seal. In another aspect, the stud has a lower leg or other extension projecting therefrom, and which is fully encased by the lead shroud, particularly for increasing the current carrying capability of the connector.
