Method and apparatus for reactive gas remediation
Patent No. 9,227,156
Disclosed are methods, materials, apparatus and systems for removing or suppressing ambient levels of reactive gas contaminants, particularly acidic gases, using particles of zeolite, sepiolite or other suitable carrier material impregnated with at least one treatment compound selected to react with the acidic gas(es). The methods involve contacting a contaminated gas stream with the impregnated carrier materials whereby at least a portion of the reactive gases contacts the treatment compound and reacts, thereby consuming the reactive gas molecules.

Amphiphile-modified sorbents in smoking articles and filters
Patent No. 9,232,821
Smoking articles which involve the use of amphiphile-modified sorbents are disclosed. The amphiphile-modified sorbent has at least one amphiphilic compound bound to an inorganic molecular sieve substrate. The amphiphile-modified sorbent selectively removes certain constituents from cigarette smoke, while maintaining other constituents, such as those that contribute to flavor. Methods for making cigarette filters and smoking articles using amphiphile-modified sorbents, as well as methods for smoking a cigarette containing an amphiphile-modified sorbent, are also provided.

High speed object inserter and related methods
Patent No. 9,232,820
An apparatus for inserting one or more objects into a filter component of a tobacco rod includes a storage apparatus that stores a plurality of the objects, each object having a predetermined volume; an inserter wheel that receives the objects stored in the storage apparatus, and inserts the objects into a band of filter material, the inserter wheel having an outer periphery with a plurality of pockets defined in the outer periphery and distributed about the outer periphery. Each pocket has a shape configured to support one of the objects with between about one quarter and about one half of the volume of the object received in the pocket. The remainder of the volume of the object protrudes from the pocket above the outer periphery of the inserter wheel. A method of inserting one or more objects into a filter component of a tobacco rod is also described.

Stave hone assembly for use with rotating shafts
Patent No. 9,233,447
A hone insert is adapted for use in a rotating shaft system that has a segmented stave bearing housing. The stave bearing housing includes multiple stave bearing inserts that retain the rotating shaft. The hone insert is supported by a mounting bar section and a support pad that bears a hone layer against the face of the rotating shaft. Accordingly, as the shaft rotates against the hone layer, the surface of the shaft is made more smooth.
