Abstract: A composite battery container for housing one or more cell elements comprising positive and negative plates alternately interleaved with separator material includes a battery housing defining one or more cell compartments. The cell compartments have resilient, flexible spacer and plate-rest ribs integrally formed in the sides and bottom of the cell compartments, but having different material properties than the battery housing. The battery housing is made of a rigid, low cost plastic material, while the ribs are a flexible thermoplastic elastomer. The flexible ribs elastically deform when a cell element is disposed within the cell compartment and return to a substantially non-deformed, originally molded position when the cell element is removed. The ribs are formed in any suitable orientation and at any suitable acute or obtuse angle from the cell compartment walls.

Abstract: A cast-on strap for use in connecting current collecting lugs in battery systems is disclosed. In the most preferred embodiment, the invention includes a caston strap formed of electrically conductive material, such as lead, having a first elongate portion in electrical contact with a line of spaced apart battery plate lugs. The connector strap includes a second portion lying in a plane which is perpendicular to that of the elongate portion so that the latter is laterally displaced. The preferred cast-on strap also includes an angularly extending portion between the elongate portion and the second portion. Increased current transfer efficiency is achieved using the strap of the present invention.

Abstract: A single service container having a closure cap with a recessed portion extending generally interiorly of said container. A tab is defined by a score line which, upon deflection of a an actuating member on the cap, substantially separates from the remainder of the recessed portion forming an opening in the cap. Once the tab has been separated, it is deflected through the opening and prevented from obstructing the opening by the actuating member being positioned in an interference relationship between the interior of the container, adjacent the opening, and the tab.

Abstract: A plastic container having a reinforcing ring in its base to strengthen the base. The ring reinforces the base to prevent deformation of the base which would result in an unstable container and also reduces the potential for stress cracking found in one-piece containers having reinforcing ribs in the base structure. The reinforcing ring has a weight that is less than the weight of a typical base cup used to provide a supporting surface for a two-piece composite bottle. The ring is attached to the base portion of the container by one of three methods: molding the reinforcing ring into the base; providing a ring and a base which snap fit together, or adhesively bonding the ring to the base of the container. When the contianer is filled with a carbonated beverage, the pressure within the container acts to maintain the ring in an assembly relation with the container base in which the ring reinforces the base and acts to maintain the structural integrity of the base by resisting eversion of the base.

Abstract: A plastic container is provided which includes a stabilizing ring attached to the base structure of a blow molded bottle for improving the vertical stability to the container when supported upon a horizontal surface. The container includes a plastic bottle having a tubular sidewall and a base structure closing the bottle at an end of the sidewall. The base structure includes an outer wall having a radially inner lower edge portion, an inner wall within the outer wall which has an axial recessed portion extending upward into the container. The lower edge portions of the inner and outer walls are merged together. The stabilizing ring is attached to the base structure and extends radially outwardly and downwardly forming an annular supporting surface at the lower edge of the ring upon which the container is supported.

Abstract: The metal fouling which is deposited in the bores and other interior parts of firearms as a result of firing is selectively removed by an electrochemical process which is innocuous to the ferrous base metal of the firearm. A low voltage d-c potential is applied between the ferrous base metal of the firearm to be cleaned, which is maintained as the positive electrode with respect to an auxiliary electrode which is, for example, inserted into the bore and electrically insulated therefrom. An electrolyte occupying the space between the interior of the bore and the auxiliary electrode is selected to be non-oxidizing to the ferrous base metal and capable of solubilizing the electrochemically oxidized metal fouling to be removed. Metal fouling or deposits are completely removed without affecting the ferrous base metal of the bore.
