Abstract: An electro-magnetic coil assembly mounted to a clutch assembly, the electromagnetic coil assembly including a coil mounted within an annular coil housing and a flexible armature plate. The coil assembly adapted to generate an electromagnetic field between the coil and the armature plate for attracting the armature plate to the coil assembly. The flexible armature plate includes an annular plate with an outer edge and an inner edge, the outer edge defining an outer periphery, the inner edge defining an inner periphery. Tangs spaced about the inner periphery extending radially inward from the inner edge. Inner notches spaced about the inner periphery of the annular plate and extending radially outward to a point at least halfway in the radial direction between the inner edge and the outer edge. Outer notches spaced about the outer periphery between and extending radially inward.

Abstract: A lift device includes a wheel assembly coupled to a frame. The wheel assembly includes a rim having an inner barrel, an outer barrel, and a lip defining a first surface and a second surface. The lift device also includes an adapter plate and an axle having a first end coupled to the frame and a second end including a hub. The adapter plate includes a barrel portion defining a first face and a second face, a hub portion directly coupled to the hub, and a transition portion extending between the barrel portion and the hub portion. The second surface of the lip engages the first face of the barrel portion when the wheel assembly is in a first configuration and the second face of the barrel portion when the wheel assembly is in a second configuration thereby reducing a track width of the lift device.

Abstract: A process for controlling the water balance and the concentration of impurities in an electrolytic zinc plant circuit with which is operated at least one selective zinc precipitation (SZP) process plant which comprises one or more of the steps(a) a two-stage SZP process plant in which a compound containing calcium carbonate is used in the first-stage to precipitate portion of the zinc in incoming solution, and a compound R containing zinc oxide, preferably calcined zinc sulphide concentrate, is used to precipitate most of the remaining zinc;(b) displacement of the zinc depleted solution associated with solids leaving the SZP process plant by solution drawn from the electrolytic zinc plant circuit, and(c) use of a compound R with a particular average particle size.
