A storage battery cell having a dry element includes a reservoir containing an electrolyte precursor therewith. To activate the cell, it is filled with water after which the reservoir is punctured by the use of a specialized tool. The tool is forced through an opening in the battery cover puncturing first the top wall and then the bottom wall of the reservoir. In this position, the tool is locked in place against subsequent removal.

An alloy feedstock for semi-solid metal injection molding. The alloy feedstock is an alloy material in particulate form and has a heterogeneous structure, a temperature range at 20% of the height of the peak of the main melting reaction greater than 40.degree. C., and having a ratio of the height of the peak of the eutectic reaction to the height of the main melting reaction of less than 0.5.

An active carbon material includes a gas permeable surface coating of particulate hydrophobic material which renders the active carbon waterproof while still permitting it to adsorb undesirable components. Preferably the hydrophobic material is polytetrafluoroethylene having a mean particle size of substantially a tenth of a micron. Active carbon is waterproofed by immersing it in an aqueous suspension of the hydrophobic material and then drying the active carbon to remove the water to leave the...

Activated cathode for use in aqueous solution electrolysis comprises (a) a base plate made of a metal selected from the group consisting of titanium, tantalum, zirconium, niobium or an alloy essentially consisting of combination of those metals and (b) a metal oxide layer formed on the surface of the base plate, said metal oxide essentially consisting of an oxide of one or more metal elements selected from the group consisting of ruthenium, rhodium, palladium, osmium, iridium and platinum in the...

A process for the manufacture of thin activated electrodes including a base metal, which can be iron, cobalt or nickel, with a good adhering active surface layer. Both the base metal and the surface layer are galvanically sequentially deposited as separate layers on a removable electrically-conductive carrier. The surface layer is deposited as an activatable alloy including the base metal and a leachable metal, particularly zinc. The galvanizing deposited layers are subsequently separated as a u...

The present invention is directed to an activated carbon made from macadamia nuts. The macadamia nuts each comprise an outer husk, a shell and a kernel. The shell is used as a material of the activated carbon. The shell is separated from the husk and the kernel and subjected to carbonization and activation processes to obtain the activated carbon.

Ion exchange activated cellulose in the form of porous bodies, caps, tubes, beads, granules or powders is prepared by reacting unregenerated cellulose with a compound having ionizable chemical groups which impart ion exchange properties to the cellulose reaction product and then regenerating said product.

Activated immunoglobulin which is useful as an eosinophilia-suppressing agent, immunomodulating agent, therapeutic agent for autoimmune diseases, anfiinflammatory agent and antiallergic agent is obtained by admixing immunoglobulin with a histamine component and then substantially or completely removing the histamine component. The histamine component may be removed or separated by dialysis, gel filtration, adsorption chromatography, ion exchange chromatography, or affinity chromatography. The me...

A structure includes a foundation member and multiple piezoelectric actuator/sensor elements disposed transversely about the structure. The elements are bound to the face of the foundation member to permit force transmission between the elements and the foundation member. The elements include restriction plies orientated oppositely for alternating transverse elements. The elements have a preferred direction of motion and when two adjacent elements are oppositely poled, this relates to a torsiona...
