  • Patent number: 8969237
    Abstract: Disclosed are, inter alia, methods of forming coated substrates for use in catalytic converters, as well as washcoat compositions and methods suitable for using in preparation of the coated substrates, and the coated substrates formed thereby. The catalytic material is prepared by a plasma-based method, yielding catalytic material with a lower tendency to migrate on support at high temperatures, and thus less prone to catalyst aging after prolonged use. Also disclosed are catalytic converters using the coated substrates, which have favorable properties as compared to catalytic converters using catalysts deposited on substrates using solution chemistry. Also disclosed are exhaust treatment systems, and vehicles, such as diesel vehicles, particularly light-duty diesel vehicles, using catalytic converters and exhaust treatment systems using the coated substrates.

  • Patent number: 8968760
    Abstract: A method for attaching an implant to tissue is disclosed. In embodiments, a method includes applying a sprayable material to tissue, the sprayable material possessing functional groups capable of binding to tissue. The sprayable material also possesses functional groups capable of binding to an implant. In embodiments, the functional groups capable of binding to an implant include nucleotides. In such a case, the implant possesses complementary nucleotides capable of binding to the nucleotides on the sprayable material, thereby permitting hydrogen binding between the two. The implant may thus be affixed to tissue, and repositioned as necessary, prior to more permanent attachment utilizing means such as sutures, tacks, etc.

  • Patent number: 8961867
    Abstract: Refractory metal powders are dehydrided in a device which includes a preheat chamber for retaining the metal powder fully heated in a hot zone to allow diffusion of hydrogen out of the powder. The powder is cooled in a cooling chamber for a residence time sufficiently short to prevent re-absorption of the hydrogen by the powder. The powder is consolidated by impact on a substrate at the exit of the cooling chamber to build a deposit in solid dense form on the substrate.

    Abstract: In a method for producing a vehicle heater (10), a main body (12) of the vehicle heater (10) is equipped with a non-intrinsically safe heat conductor layer (14), and a sensor device (16, 18, 20) for detecting exceedances of a temperature threshold value. To form the sensor device (16, 18, 20) a sensor layer (16) is sprayed on without the main body (12) being exposed to temperatures normal for baking processes. A vehicle heater (10) is equipped with a main body (12) carrying a non-intrinsically safe heat conductor layer (14), and with a sensor device (16, 18, 20) allocated to the heat conductor layer (14) and provided to detect the exceedance of a temperature threshold value. The sensor device (16, 18, 20) comprises a sprayed-on sensor layer (16) produced without the main body (12) assuming temperatures that are normal for baking processes.

    Abstract: [Problem] To provide a means for forming a thin-film in a desired part of an object to be treated. [Solution] The thin-film formation means according to the present invention is part of a thin-film formation method which supplies electricity to a raw-material gas in a reduced pressure container, converting the raw-material gas to plasma, and irradiates the plasma, thus forming a thin-film on the surface of an object to be treated. Therein, the effect of a magnetic field generated by a magnetic field generating means is used to form the thin-film in a desired part. The effect of the magnetic field focuses the flux of the plasma in a desired part of the surface of the object to be treated, thus enabling the thin-film to be formed in the desired part.
