Abstract: The present invention relates to a dry composition of materials to be used n a battery system. The dry composition comprises a mixture consisting of sodium hydroxide and sodium oxide. In a first reservoir in the battery system, the mixture is present in an amount sufficient to form with water a heated sodium hydroxide electrolyte solution having a 15% by weight concentration of sodium hydroxide. In a second reservoir in the battery system, the mixture is present in an amount sufficient to form with water a heated sodium hydroxide electrolyte solution having to up to about 75% by weight concentration of sodium hydroxide. The present invention also relates to a battery system and a method for generating electrical power which utilize the aforementioned dry composition of materials.

Abstract: A water-activated sonobuoy system is provided to release a plurality of sle, water-activated sound sources into a water environment. In the preferred embodiment, a plurality of water-impenetrable tubes are attached and sealed at one end to a float and are open on their other end. A plurality of water-activated sound sources are stored within each tube. Water-degradable barriers are used to isolate each of the sound sources within the tubes. Water-degradable endcaps are used to seal the open end of each tube. Upon being placed in the water, the endcaps dissolve to release the first sound source in each tube. This in turn exposes the first barrier in the tube to water. Each exposed barrier subsequently dissolves in the water to release the next water-activated sound source in each tube. This process continues until all sound sources have been released into the water. Appropriate venting is provided in both the barriers and the float to permit controlled water entry from the bottom of the tubes.

Abstract: A surgically implantable infusion port includes a housing portion, a penetrable elastomeric septum portion which cooperates with the housing portion for defining an interior cavity and a catheter element which extends outwardly from the interior cavity for dispensing medication therefrom at a predetermined location in the body of a patient. The elastomeric septum portion is penetrable by a hypodermic needle for dispensing medication in the interior cavity, and it is laterally compressed to enhance the ability of the septum portion to reseal itself after being repeatedly penetrated. A septum assembly including a similar laterally compressed septum element can also be utilized as a penetrable barrier between various liquids and gases.

Abstract: An electrical access port assembly includes an access port unit which is surgically implantable in the body of a patient and a pair of conductive needles which are operative for supplying electrical energy to the access port unit. The access port unit includes a body portion having a pair of access openings therein, a pair of penetrable elastomeric septa in the access openings, and an interior partition which divides the interior of the body portion into a pair of enclosed interior cavities, each of which is accessible through one of the penetrable septa. The access port unit further icludes an electrical contact in each of the cavities and a conductor wire attached to each of the contacts. The septa of the access port unit are self-sealingly penetrable by the conductive needles to electrically connect the needles to the contacts in the cavities in order to supply electrical energy to a predetermined location in the body of the patient through the conductor wires.

Abstract: An implantable infusion port for dispensing medication in the body of a patient comprises a septum which is preferably integrally molded from a nontoxic, rubberized material and has an interior cavity formed therein for receiving medication in the septum, and a catheter element which extends from the cavity to the exterior of the septum for dispensing medication in the body of a patient. The septum has a rounded dome-shaped configuration, and the infusion port is surgically implantable in the body of a patient so that it is positioned beneath the skin and subcutaneous tissue of the patient. After the infusion port has been implanted in the patient, medication can be introduced into the cavity by inserting a hypodermic needle through the skin of the patient and through the side wall of the septum.

Abstract: This invention provides a means to increase the energy density of two eleochemical systems by using the by-product of each system as one of the necessary ingredients of the reactants of the other system. For example:(a) 2Li+H.sub.2 O.sub.2 .fwdarw.2LiOH(b) 2LiOH+3H.sub.2 O.sub.2 +2Al.fwdarw.2LiAlO.sub.2 .dwnarw.+4H.sub.2 Owhere the LiOH from (a) is used in (b) and the H.sub.2 O from (b) is used to fulfill the dilution requirements of (a).

Abstract: A tin and mercury free aluminum alloy of specific composition for use as an node in fuel cells and electrochemical couples and particularly in a silver oxide-aluminum battery comprising high purity aluminum alloyed with gallium and magnesium in specified quantities. The aluminum in combination with the gallium provide desired unique electrochemical properties. The magnesium, when the anode material is suitably heat treated, increases the tensile modulus of the alloy.
