Abstract: An apparatus for stacking corrugated boards and permitting stacks of corrugated boards to be alternatively arranged together with one above another in a zigzag order. A carrier is mounted for collecting corrugated boards from the output end of the finished product conveyer of an automatic corrugated board fabrication system, a shifting mechanism is controlled to shift the carrier horizontally, a counter is controlled to count the number of pieces of the corrugated boards being stacked, and a suspension mechanism is controlled to lift or lower the carrier.

Abstract: A storage battery has a battery housing which includes a rectangular casing with an open top end and a plurality of cell compartments, and a cover device sealed to the open top end of the casing. The cover device includes a main cover part and a sub-cover part. The main cover part has a plate body with a top face that is formed with a plurality of adjacent rectangular chambers. Each of the chambers is aligned with a respective one of the cell compartments and is confined by first and second longitudinal walls and first and second transverse walls. Each of the chambers has a bottom formed with a vent hole, a return hole, and an upwardly projecting partition unit that confines a condensate groove in the chamber. The sub-cover part is sealed to the main cover part at top edges of the longitudinal and transverse walls and the partition unit of each of the chambers to seal a top end of the condensate groove in each of the chambers.
