Patent number: 8658248Abstract: A method for atomizing a liquid including providing an atomizer having a liquid supply conduit having an outlet at one end, a gas supply conduit opening into a port in the liquid supply conduit upstream of the outlet, and a means for imparting vibrational energy to the atomizer. In an embodiment, the liquid supply conduit and gas supply conduit are coaxially displaced relative to one another. The method further includes flowing liquid through the liquid supply conduit to the outlet while simultaneously flowing gas through the gas supply conduit, and imparting vibrational energy to the atomizer to atomize the liquid exiting from the outlet. The introduction of gas at the port results in a spray of droplets with improved dimensional properties.Type: GrantFiled: December 28, 2006Date of Patent: February 25, 2014Assignee: 3M Innovative Properties CompanyInventors: Edward J. Anderson, Jesus R. Ramos

Patent number: 8652578Abstract: A method of forming a cured coating composition on an automobile component is provided. The method utilizes a coating compound including a radical polymerizable compound and an organoborane initiator and includes the step of applying the coating composition to the automobile component. The organoborane initiator is complexed with a bi-functional noncyclic blocking agent that has a carbon backbone and two organoborane complexing moieties. The two moieties are different from each other and are selected from the group of an amine moiety, a thiol moiety, and a phosphine moiety. In addition, the two moieties are separated from each other by two to four carbon atoms to increase the nucleophilicity of the blocking agent towards the organoborane initiator. The organoborane initiator is decomplexed from the blocking agent thereby forming a radical that is used to polymerize the radical polymerizable compound and cure the coating composition on the automobile component.Type: GrantFiled: June 24, 2010Date of Patent: February 18, 2014Assignee: BASF SEInventors: David Cranfill, Keith E.

Patent number: 8650753Abstract: A seal (48) between a compressor rotor blade (26) and compressor casing (28) comprises an abradable structure (59) on the compressor casing (28). The abradable structure (59) comprises a metallic foam (60) having pores (66, 68). The metallic foam (60) has a first a region (62) and a second region (64). The first region (62) of the metallic foam (60) is arranged adjacent to the compressor casing (28) and the second region (64) of the metallic foam (60) is spaced from the compressor casing (28) by the first region (62) of the metallic foam (60). The pores (68) of the second region (64) of the metallic foam (60) contain an abradable material (70) and the pores (66) of the first region (62) of the metallic foam (60) do not contain an abradable material.Type: GrantFiled: October 8, 2009Date of Patent: February 18, 2014Assignee: Rolls-Royce, PLCInventors: Christopher Sellars, Glen Pattinson, John T Gent
