Abstract: A block of bags for a product filling process includes a plurality of bags stacked in overlying relationship. Each bag of the block has a top edge, a bag mouth and opposite first and second side edges. First and second weakened segments extend from adjacent edge points on respective opposite lateral edges of the bag. A central line of perforations extends between inner ends of the first and second weakened segments. A tear-off region is defined between the central line of perforations and the top edge. During automatic filling of the bag, the weakened segments are torn to form an open bag mouth, and the central line of perforations is torn after filling to separate the bag from the block. The weakened segments can be cuts and are spaced from the lateral edges of the bag to define frangible bridges at the lateral edges, wherein the frangible bridges are broken during opening of each bag.

Abstract: A conveyor apparatus for stacked articles, such as stacked plastic or paper bags, includes a frame, and a plurality of sprocket assemblies about which one or more conveyor chains extend. The apparatus includes a plurality of wicket wire holding assemblies mounted on the chains at spaced apart intervals for intermittent, incremental movement along a conveyor path defined by the conveyor chains. Each of the holding assemblies includes a pair of support arms, and an adjustment mechanism for adjusting the spacing between the arms. The apparatus includes an arrangement for simultaneously adjusting the spacing between the support arms of all of the holding assemblies, including an adjustment drive chain trained about the sprocket assemblies, and a mechanism for moving the adjustment drive chain relative to the conveyor chains of the apparatus.

Abstract: An electric energy storing device constructed from uniquely designed components. Each component includes a first nonconductive frame, having an opening and a predetermined perimeter. Mounted, by its peripheral edge, on the first nonconductive frame, is a plastic sheet, having a centrally positioned opening. The plastic sheet may be made from conductive carbon plastic or from nonconductive, ion-permeable plastic. Mounted to the centrally positioned opening of the plastic sheet is a second nonconductive frame. Each of the frames has a weld bead thereon and a plurality of components are welded together to form an operational device. The provision of a second, centrally located weld prevents deformation or defection at the center of the welded components.

Abstract: A module for liquid electrolyte, electric energy storing devices. The module includes a double-walled container having an innerwall and an outerwall and a rim. The container includes a first well for holding liquid electrolyte electric energy storing devices and which is defined by the inner wall. The container also includes a first electrolyte reservoir having a shelf and a lid for covering the first reservoir. The innerwall and outerwall define a second electrolyte reservoir which surrounds the first electrolyte reservoir so that the first and second reservoirs are in nested relationship. The reservoirs are designed so that a physical puncture of the module will cause the electrolyte from the first reservoir to mix with the electrolyte from the second before it leaks from the module.
