Inventor: KANG YOUSHU
IPC: B01F27/74
Filed: 2005-12-13
Abstract: An apparatus for processing materials, which is used to process the materials introduced thereinto, comprises a operating assembly and a driving assembly, wherein the operating assembly comprises a first cylindrical member and a second cylindrical member arranged in the first member, thereby forming a receiving chamber between the first member and the second member to receive the materials to be treated, the second member is driven by the driving assembly and rotates relatively to the first member, and the surface of the second member facing the receiving chamber is arranged with disturbing parts which can provide axial force paralleling with the columella line of the first member. Since the second member is arranged with disturbing parts, the apparatus for processing materials of the invention can treat the materials to be treated adequately, control the retain time of the materials to be treated holding in the receiving chamber, and prevent the materials to be treated from entering into the mixing blind zone, thus all of the materials in the receiving chamber can be treated adequately.

Patent CA-2593154-A1 (CA)
Inventor: DENNIS WILLIAM D
IPC: E04D13/08
Filed: 2006-01-10
Abstract: An apparatus eliminates ice/snow formation at roof edging and in this regard comprises a mesh casing and salt-based fill material. The apparatus may be placed into a typical gutter assembly adjacent a roof edge. The casing is flexible and degradable and comprises a salt-retaining surface, a matter-engaging surface, and a plurality of mesh apertures. The mesh apertures each comprise a maximal aperture dimension. The fill material comprises a plurality of salt pellets, each pellet comprising a minimal pellet dimension. The minimal pellet dimension is greater in magnitude than the maximal aperture dimension and thus the fill material is retained by the salt-retaining surface. A portion of the fill material dissolves in water when water contacts the fill material thus forming a flowable solution. The solution inherently has a depressed freezing point for preventing ice formation. Thus, the water-based solution flowing from the apparatus functions to eliminate ice at roof edging.
