Abstract: A router bit kit includes a plurality of router bits, a plurality of router bit holders and a container. Each of the plurality of router bits has a cutting surface configured to produce a cut having a three dimensional kerf profile. Each of the plurality of bit holders corresponds to at least one of the plurality of f router bits. Each of the plurality of bit holders has a three dimensional kerf profile portion that matches the three dimensional kerf profile which the corresponding router bit is configured to produce. The container is configured to retain the plurality of router bits and the plurality of holders.

Abstract: An organic-inorganic hybrid is derived from combining at least one inorganic alkoxide and a hydrogenated sulfonated block copolymer containing a controlled distribution copolymer block of a conjugated diene and a mono alkenyl arene, where the controlled distribution copolymer block has terminal regions that are rich in conjugated diene units and a center region that is rich in mono alkenyl arene units. The inorganic alkoxide may be an alkoxysilane compound or composition.

Abstract: Fuel cells incorporating a novel ion-conducting membrane are disclosed. The membrane comprises a plurality of acid-stable polymer molecules each having at least one ion-conducting component covalently bonded to at least one flexible connecting component. The membrane has ion-conducting components of the polymer molecules ordered such that a plurality of continuous ion-conducting channels penetrate the membrane from a first face to a second face and such that the ion-conducting channels are situated in an elastic matrix formed by the flexible connecting components. A preferred membrane is obtained by (1) sulfonating SEBS with sulfur trioxide under conditions that result in greater than 25 mol % sulfonation and (2) heating the polymer.
