Abstract: A web making machine is monitored to identify at least one cross-machine direction (CD) actuator that is developing local mapping problems. The identified CD actuator and a segment of surrounding actuators are probed to determine a performance curve for the actuator. The center of an insensitivity region of the performance curve is selected as an optimal mapping alignment setting for the identified actuator with the setting for the actuator being updated. Global smoothing may also be accomplished by probing a global smoothness factor to generate a corresponding performance curve that is then similarly used to select an optimal value for the smoothness factor.

Abstract: Fast cross direction caliper control recovery time in a sheet making machine during startup of the machine after a sheet break is achieved provided that a preselected time duration measured from the occurrence of the sheet break to the clearing of sheet break has elapsed. One or more of three operations, namely, open loop calender stack conditioning, a conditioning of a measurement from a sensor for measuring caliper of the sheet and a closed loop change in a set of control tuning parameters of a PI controller for providing feedback caliper control of actuators associated with the calender stack can be selectably performed. The operations have an order of precedence. The first and second can be performed concurrently if the selected time duration for both are identical, the first is performed before the third if both are selected and the second is performed before the third if both are selected.

Abstract: A golf ball constructed of a molded outer cover defining an outer diameter of the golf ball of about 1.8 to 2.5 inches, and preferably between 1.8 and 2.2 inches. One or more inner materials within the golf ball is of a sufficient density to allow the golf ball to float in water. The golf ball may comprise an inner core of a light weight material of sufficient density to allow the golf ball to float. The golf ball will have the characteristics and feel of a conventional golf ball while being able to float. The increased size of the golf ball will give the beginning golfer an easier target to strike with the club face thereby improving his or her confidence in ball striking ability. The increased size will also increase the wind resistance and thereby overemphasizing balls hit with improper spin, resulting in quicker learning time. Better golfers can use this feature to practice and perfect cut and draw shots. The golf ball may used during actual rounds of golf or in training on the driving range.

One or more inner materials within the golf ball is of a sufficient density to allow the golf ball to float in water. The golf ball may comprise an inner core of a light weight material of sufficient density to allow the golf ball to float. The inner core may include a cork material. An elastic material such as elastic windings may be wrapped around the inner core. The golf ball will have the characteristics and feel of a conventional golf ball while being able to float. The increased size of the golf ball will give the beginning golfer an easier target to strike with the club face thereby improving his or her confidence in ball striking ability.
