Patent number: 10053779Abstract: A coating process for applying a bifurcated coating to an article is disclosed including applying an aluminizing slurry to a first portion of the article, applying a chromizing slurry to a second portion of the article, and simultaneously heat treating the article, the aluminizing slurry, and the chromizing slurry. Heat treating the aluminizing slurry forms an aluminide coating on the first portion of the article and an aluminide diffusion zone between the article and the aluminide coating. Heat treating the chromizing slurry forms a chromide coating on the second portion of the article and a chromide diffusion zone between the article and the chromide coating. The first portion and the second portion are both maintained in an unmasked state while applying the aluminizing slurry and the chromizing slurry and during the heat treating.Type: GrantFiled: June 22, 2016Date of Patent: August 21, 2018Assignee: General Electric CompanyInventors: Liming Zhang, Christopher Edward Thompson, Limin Wang

Publication number: 20170321402Abstract: A drain cleanout features a flexible drain auger, a mounting section supported solely on a drain pipe, a drum section carried by the mounting section and storing the auger, a rotational connection coupling the mounting section and the drum section, and a rotational drive unit carried by the mounting section and operable to drive rotation of the drum section. A feed mechanism for the flexible auger features a helical slot in the auger cable and a thin disc received in the slot and supported at a fixed longitudinal position in a travel direction along which the drain auger exits and re-enters the drum. Rotation of the auger cable with the drum cause longitudinal displacement of the auger cable in the travel direction.

Publication number: 20170295796Abstract: The present invention relates to an antimicrobial composition comprising an isothiazolinone, such as 1,2-benzisothiazolin-3-one, and a zinc compound selected from zinc salts, zinc oxides, zinc hydroxides or combinations thereof. Useful zinc salts include for example, oxides, sulfates, chlorides, and combinations thereof. In use, the zinc from the zinc compound enhances the antimicrobial activity to the isothiazolin-containing composition. This enhancement permits achieving the desired antimicrobial activity at a lower usage rate than is achieved using the isothiazolinone in the absence of the zinc compound. The antimicrobial composition can also contain co-biocides, such as pyrithiones, including zinc pyrithione or copper pyrithione.Type: ApplicationFiled: June 29, 2017Publication date: October 19, 2017Inventors: Nicholas Edward Thompson, Malcolm Greenhalgh, Fitzgerald Clarke
