Abstract: A mounting device for removably attaching a support apparatus to a work surface, the support apparatus having a first mounting bracket with a first attachment plate and a second mounting bracket with a second attachment plate. The mounting device comprises a first clamp slidably connected to the first mounting bracket and a second clamp slidably connected to the second mounting bracket. Each clamp has a first wall, a second wall, and a third wall. The first attachment plate is positioned between the first and third walls of the first clamp, and the second attachment plate is positioned between the first and third walls of the second clamp.

Abstract: A support integral with a housing for a paper shredder having a plurality of cutting cylinders with cutting shafts. The support has at least one rib extending outward from at least one wall of the housing toward the cutting shafts of the cutting cylinders.

Abstract: An integrated filter and sleeve assembly has an annular non-porous sleeve having opposing open ends and an outer circumferential wall with an inner surface. The integrated filter and sleeve assembly also has a filtration block disposed within the annular sleeve between the open ends. The filtration block includes a mixture of filtration media and a binder. A seal is formed between the inner surface and the filtration block by applying heat to the annular non-porous sleeve and the filtration block.

Abstract: A cutting cylinder for a paper shredder has a shaft with a first end and a second end. A plurality of spaced-apart cutter discs are arranged on the shaft between the first and second ends of the shaft. Each cutter disc has an inner surface defining an inner diameter. In addition, the shaft has a first outer surface lining the inner surface of at least one cutter disc, and a second outer surface adjacent to at least one cutter disc. The second outer surface has an outer diameter greater than the inner diameter of the adjacent cutter disc.
