Abstract: An electric storage battery and method of manufacture thereof characterized by a feedthrough pin which is internally directly physically and electrically connected to an inner end of a positiv electrode substrate. A C-shaped mandrel extends around the pin and substrate end enabling the pin/mandrel to be used during the manufacturing process as an arbor to facilitate winding layers of a spiral jellyroll electrode assembly. The pin additionally extends from the battery case and in the final product constitutes one of the battery terminals with the battery case comprising the other terminal. Active material is removed from both sides of the outer end of the negative electrode in the jellyroll to allow room for adhesive tape to secure the jellyroll. The electrolyte is injected through the open end of the case after the endcap is welded to the negative electrode but before sealing the endcap to the case. The electrolyte is preferably injected through the C-shaped mandrel to facilitate and speed filling.

Abstract: A soaking apparatus utilizing a soaking basin and a disposable liner configured to fit within the basin cavity. The basin is comprised of a material layer formed to define an integral floor and a peripheral wall projecting upwardly therefrom. The basin floor and peripheral wall together define the boundary of a basin cavity. An elongate protrusion protrudes from the floor into the basin cavity between left and right foot areas. The liner is comprised of a thin (e.g., 3-12 mils) material layer formed to define an integral floor and peripheral wall projecting upwardly therefrom. The liner floor and peripheral wall are dimensioned to closely nest within the basin cavity. The liner floor also defines left and right foot areas spaced by a protrusion projecting into the liner cavity. The underside of the liner protrusion forms a concave recess for accommodating the basin floor protrusion.

Abstract: A sanitary liner for a manicure or pedicure soaking basin. The sanitary liner is formed from a plastic or rubber which is light and inexpensive so that it can hold soaking solution when necessary and dump out the solution when necessary. It is disposable so that customers of beauty salons can each have soaking solution held in a different liner and thereby avoid the possibility of soaking in a basin that is contaminated with pathogens from a prior customer. It fits smoothly inside the reservoir of a common commercial salon soaking basin. It may be rigid or it may be pliable so that fluid pressure causes it to conform to the inside of the reservoir.
