Abstract: Disclosed are embodiments of battery stacker machines, including z-fold stacker machines, configured to provide a rolling transfer of a battery layer so as to reduce scrubbing. In some embodiments, the layer is flexed onto an arcuate surface using a vacuum or other force. The arcuate surface is then rotated to release the layer at a desired transfer location. For instance, the desired transfer location may be on top of a stack or onto another arcuate gripper surface.

Abstract: An apparatus for cleaning containers which includes a tank for holding a cleaning fluid. A rack which includes clamps for clamping the containers to be cleaned is movable from a loading position in an upper portion of the tank by sliding engagement with a track to a cleaning position in a lower portion of the tank wherein the brushes are in cleaning engagement with the containers. The rack is pivotable whereby the containers may be loaded in an upright position in the rack and may thereafter be pivoted to a sliding position wherein the rack slides downwardly along the track to its cleaning position.

Abstract: A monitoring system for the notification of locations external to the area being monitored of a prolonged absence of motion within the area being monitored is disclosed consisting of a clock, an electronic counter designed to record the pulses emitted periodically by the clock and to signal an alarm trigger when a pre-programmed number of pulses are recorded, and reset means such that if activated the counter will return to zero thereby preventing activation of the alarm trigger. Also, this system uses circuit means incorporating a photoelectric cell to automatically increase the pre-programmed number of pulses necessary to cause activation of the alarm trigger during periods of darkness and to automatically return the counter to its original pre-programmed condition with the presence of light.
