Abstract: Membrane electrode assemblies are described that include an ion conductive membrane a catalyst adjacent to the major surfaces of the ion conductive membrane and a porous particle filled polymer membrane adjacent to the ion conductive membrane. The catalyst can be disposed on the major surfaces of the ion conductive membrane. Preferably, the catalyst is disposed in nanostructures. The polymer film serving as the electrode backing layer preferably is processed by heating the particle loaded porous film to a temperature within about 20 degrees of the melting point of the polymer to decrease the Gurley value and the electrical resistivity. The MEAs can be produced in a continuous roll process. The MEAs can be used to produce fuel cells, electrolyzers and electrochemical reactors.

Abstract: A portable device for coupling hearing aids to a telephone, whereby the hearing aid/telephone user simultaneously receives a signal transmitted from the device to the user's hearing aid(s) while receiving an audio signal via the telephone handset. The device may inductively couple the telephone to the user's hearing aid(s), or the device may use some other method of wireless communication to couple the telephone to the user's hearing aid(s).

Abstract: Approaches are described for producing porous, polymer electrodes with good characteristics for incorporation into polymer batteries. Two preferred processes are presented. The polymer electrodes can be subjected to additional processing to increase their porosity and electrical conductivity. The polymer electrodes preferably are incorporated into a polymer battery where the components are laminated together.

Abstract: A low profile heat-sealable adsorbent filter for ostomy appliances is provided. The filter comprises a heat-sealable microporous film layer, a filter layer of melt-blown microfibers loaded with adsorbent particles and a cover layer. The microporous film layer provides for rapid release of flatus or other gas in having a Gurley value of less than about 100 seconds/50 cc. The melt-blown microfiber filter web has an estimated service life of about 3 days or more with a web basis weight of about 700 grams/m.sup.2 or less. The low profile filter can be sealed to the outside face of an ostomy appliance with a perimeter seal to provide a filter with no liquid or gas by-pass and no liquid by-pass through the filter.

Abstract: A low adhesion perfluoropolyether composition is provided. The composition comprises a copolymer prepared from a mixture of at least one monofunctional perfluoropolyether monomer and at least one difunctional perfluoropolyether monomer, each of said monofunctional and difunctional monomers having a molecular weight in the range of about 1500 to 2500.

Abstract: A crane with an anti-skewing device comprising a platform suspended under a bridge deck by two end truck assemblies supported by runways on a bridge. Each end truck assembly includes two sets of trolleys and an upper load bar interconnects the two sets of trolleys. A lower load bar is suspended from the upper load bar by a kingpin for rotation about a vertical axis. Hinge tubes support the platform on the suspension assembly for pivotal movement in a direction lengthwise of the platform. Each end truck assembly is driven by a variable speed motor. As skewing occurs a mechanical sensing mechanism senses relative movement between lower load bar and the upper load bar and provides a signal to an electronic circuit causing one or both of the motors associated with the end truck assembly on which the sensing mechanism is mounted to increase or decrease the speed of the motor and thereby correct the skew.

Abstract: Composite low surface energy liner provided by an inner layer of insoluble polymer made from a polymerizable, film-forming monomer and an outer layer of insoluble polymer made from a polymerizable perfluoropolyether monomer copolymerizable with said film-forming monomer, which layers are in-situ polymerized. The compposite low surface energy liner is especially useful as a low-adhesion backsize coating in a pressure-sensitive adhesive tape.
