Abstract: The invention relates to a display (20) comprising a package pusher (44) operated by a coiled spring (56, 103) and slidable within a slot (64) to push packages (36) forward to the front of a shelf (22), the pusher being laterally movable to accommodate various sized packages at various lateral positions along the shelf. The pusher is a part of a feed structure having ends engaging vertical grooves (26, 30) in upstanding walls (24, 28) fore and aft of the shelf and forming a part of a dispensing tray. The tray may be formed of laterally connected modules. Lateral displacement of the package pusher to accommodate various sized packages and positioning thereof may be accommodated by the provision of laterally spaced slots (101) within a shelf (22) having a forward wall to catch the forward-most package.

Abstract: A battery of series-connected storage cells is checked by:Measuring the transient elementary open-circuit voltage at the terminals of each storage cell;Comparing the said elementary voltages with the average transient voltage of the said storage cells (i.e. with the total transient open-circuit voltage divided by the number of storage cells). The battery is rejected if the difference between the said average transient voltage and one of the said elementary transient voltage becomes greater than a predetermined threshold.BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to a method and a device for checking a storage battery, more particularly a lead acid storage battery, charged and filled with electrolyte, this checking being effected in principle when the battery comes off the production line.2.

Abstract: A method of checking a storage battery with series-connected cells comprises the steps of:Passing a charging current pulse through the battery,Measuring an elementary transient voltage at the terminals of each storage cell; andComparing elementary transient voltages with the average transient voltage of the said storage cells (total transient voltage divided by the number of storage cells).The battery is rejected if the absolute value of the difference between the said average transient voltage and one of the elementary transient voltages, when the difference maintains a constant sign, becomes higher than a predetermined threshold and, when the difference changes signs, if the sum of the maximum absolute values of the differences in constant sign becomes higher than a predetermined threshold. Application: checking lead-acid storage batteries when they come off the production line.
