Abstract: Hermetic sealing of battery containers is accomplished in such containers comprising metal bodies provided with flanges by first mating the bodies so the flanges are coextensive, planar resistance welding the bodies together through the flanges and subsequently peripherally laser welding the edges of the flanges together to effect a redundant weld and an hermetic seal.

Abstract: Electrochemical cells containing highly reactive anodes are filled with a volatile electrolyte under controlled pressure conditions in a controllable pressure chamber. The cells are placed in the chamber with the fill port down and the chamber evacuated to a high vacuum for a given period of time. Thereafter, the pressure is increased to above the boiling point of the electrolyte being employed. A measured amount of electrolyte is then introduced to the chamber and the chamber is returned to atmospheric pressure and then raised to a pressure above atmospheric to force the electrolyte into the evacuated cell. The pressure is maintained at this level for a time sufficient to allow absorption of the electrolyte by the porous electrodes in the cell and then the excess electrolyte is blown from the chamber under pressure. Upon removal of the electrolyte the chamber is vented to the atmosphere and the cells removed and positioned with the fill ports up. The cells are now ready for final hermetic sealing.

Abstract: A system and method for assembling all components of a page to be printed, such as a full newspaper page consisting of both text and illustrations. The end product can be a positive or negative image on paper or film, or a final printing plate. The uniqueness of the invention resides in the combination of text matter directly from a computer memory with illustrations physically stored on part of a device. A photoelectric transducer scans the illustrative copy to generate electronic signals in real-time. These electronic signals are combined with the electronic signals generated by the computer text through a logic circuit so that each item is transmitted through a recording means such as a recording (writing) laser to provide the proper image, in the proper page location on the recorder surface.
