Abstract: The invention relates to a novel respiratory mask comprising a manifold provided with a manifold for a breathable gas supply line and a pair of nares elements connected with the manifold and a substantially hermetic seal over the nostrils of a patient and the nares elements formed by in situ spray coating of a quick-setting elastomeric material around the manifold.

Abstract: A flexible spacer for positioning a cell element in a cell compartment of a container of a storage battery includes a sheet member folded over on itself to a U-shaped configuration with the space between opposing surfaces of the sheet member defining a compartment for receiving the cell element, enabling the cell element and the spacer to be inserted as a unit into the cell compartment, the opposing surfaces of the sheet member each including a ribbed section that flexes upon insertion of the spacer and element into the cell, automatically adjusting for differences in cell element thickness.
