Abstract: A conveyor belt for use in the food processing industry includes a stainless steel substrate and nickel-boron coating material. The nickel-boron coating is applied on at least a portion of the stainless steel substrate to increase wear resistance.

Abstract: An environmentally-controlled food container, such as a refrigerator, freezer or oven, includes a plurality of walls joined at their edges and joints between adjacent walls. The joints are covered by a seaming tape which includes a plastic film layer and a mesh layer. The mesh layer is formed from a material having a coefficient of thermal expansion within ±10% of a coefficient of thermal expansion of adjacent wall material. The seaming prevents moisture and bacteria from entering the joints, and does not fracture due to thermal expansion and contraction of the walls.

Abstract: An improved apparatus and method for braking the rotation of a centrifuge rotor is disclosed comprising magnet means operable in a first condition wherein substantially no eddy currents are induced in a rotating rotor made of electrically conductive material by the magnetic flux of the magnet means and a second condition wherein eddy currents are induced into the rotating rotor sufficiently to slow the rotor. In one embodiment, magnet means is movable from a first position wherein substantially no eddy currents are induced in an electrically conductive portion of the rotating rotor by the magnetic flux to a second position wherein eddy currents are induced into the rotating rotor in a quantity sufficient to slow the rotor.
