Abstract: A cutter hub for use in an underwater pelletizer such as disclosed in U.S. Pat. No. 4,123,207, issued Oct. 31, 1978, which includes a replaceable, double or single edged blade attached to each arm of the hub with a major portion of the length of the blade being attached to and supported by the arm on the hub thereby resulting in less axial deflection with increased cutting pressure, since the rigid hub arm carries the rotational stress without deflection of the critical blade cutting surface. This arrangement produces higher quality pellets, fewer knife adjustments, reduces the radial wear pattern on the pellet die plate, permits the use of thinner, less costly blades and permits the use of single edged or double-edged blade with a useable second side.

Abstract: A pair of flyweights are mounted on a rotatable shaft and actuate a sleeve which is coaxially disposed on the shaft through a pair of radially extending control arms which are pivotally attached to the sleeve. The flyweights are biased inwardly by a pair of springs mounted on the control arms. On the opposite end of the sleeve is a bearing which provides a physical connection between the rotating sleeve and a non-rotating plate carrying a pair of movable contacts which cooperate with stationary contacts mounted on a stationary housing. The flyweights move outwardly upon rotation of the shaft against the action of the springs and move the sleeve axially along the shaft. The inward bias force of the springs decreases rapidly as the pivot connection of the control arms approaches the pivot connection of the flyweights causing an over center-type of action which results in an abrupt electrical connection between the stationary and the movable contacts.
