Abstract: A cutter assembly for a dry shaver, comprising an elongate carrier member (221); and a cutter element (1210) having a plurality of turns forming a helix, each having an arcuate cutting portion (1211) and an arcuate mounting portion following sequentially along the helix; said carrier member being disposed substantially parallel to the axis (D-D) of said cutter element; and said carrier member contacting and supporting the mounting portions of the turns and leaving the cutting portions as free-span arches.

Abstract: An anode composition for zinc/air cells comprises a metal binder added to particulate zinc. The metal binder in contact with the particulate zinc is heated to above its melting point. Upon cooling the metal binder solidifies and adheres to the zinc particle surfaces to form agglomerates wherein individual zinc particles are held bound to each other by the metal binder. Gelling agent and electrolyte can then be added to form an anode mixture. The metal binder has a melting point desirably above about 35° C. and below the melting point of zinc. A preferred metal binder for the particulate zinc is an alloy of indium and bismuth (In/Bi). Other desirable metal binders, for example, can be an alloy of indium, bismuth and tin (In/Bi/Sn) or alloy of indium and tin (In/Sn) as well as indium metal. Use of the metal binder in the anode mixture improves conductivity of the zinc particles and replaces the need to add mercury to the anode composition.

Abstract: A cartridge-connecting subassembly for a shaving razor handle including a cartridge connecting structure, a handle connecting structure, and a movable component within the cartridge connecting structure that interacts with a replaceable cartridge when it is connected. The cartridge connecting structure and handle connecting structure have outer side surfaces that mate with inwardly directed surfaces of the cartridge and handle so that the subassembly is substantially covered when it is mounted in the handle and a cartridge is connected. The subassembly has an assembly opening for receiving the movable component during assembly, a cartridge interaction opening through which the component is movable for interaction with the cartridge, and blocking structure that retains the movable component in the subassembly. The movable component is an ejector structure that is separate from the cartridge connecting structure. The subassembly is connected to the handle by staking.

Abstract: The present invention provides human corneal epithelial cell lines with extended lifespan. The cell lines are useful as an in vitro model of the human ocular surface. Methods for making and using the cell lines are also provided.
