A device that determines conditions under which a web break is more likely to occur in a printing system stores data pertaining to ink temperature or ink temperature gain. The device then implements a correlation analysis, such as a decision-tree induction analysis, using the stored data to determine if there is a correlation between the one or more attributes and the occurrence of a web break. The device has a multiplicity of ink fountains and includes a first temperature sensor that measures a first ink temperature and a second temperature that measures a second ink temperature. A controller compares the first ink temperature to the second ink temperature to determine an ink temperature gain, compares the ink temperature gain to a desired ink temperature gain range and generates an output signal based on the comparison.

A device and method that determine conditions under which a break in a web of a printing system is more likely to occur store data pertaining to one or more attributes associated with the manufacture of each web used in a plurality of printing runs. The device and method then implement a correlation analysis, such as a decision-tree induction analysis, using the stored data to determine if there is a correlation between the one or more web manufacturing attributes and the occurrence of a web break. The device and method may store web manufacturing data indicating one or more of a mill site, a web manufacturing machine, a date, a reel number, a reel set, a log position, any auxiliary web manufacturing equipment, a web tensile strength, a web moisture content and/or a coefficient of friction associated with the manufacture of the webs used in the plurality of printing runs.
摘要:
A device and a method use a decision-tree induction analysis to determine a web tension ratio range for which web breaks are less likely to occur within a printing system based on web tension data collected from a plurality of previous runs of the printing system. The device and method also measure two are more web tensions during operation of the printing system, calculate a web tension ratio and compare that calculated web tension ratio with the determined web tension ratio range. When the calculated web tension ratio falls outside of the determined web tension ratio range, the device and method alert a user to the fact that a condition leading to a web break is present and/or control the measured web tensions to drive the calculated web tension ratio to be within the determined web tension ratio range.

A golf cart towing device adaptable to the waist of a user that includes a belt, an adjusting ring, a buckle female portion, a buckle male portion, a tube, and an elastic strip. The belt has an outer surface, an inner surface, and first and second distal ends. The adjusting ring has an inner post and an outer post that defines a slot therebetween throughwhich the belt passes. The buckle female portion contains a slot through which the belt first distal end passes. The buckle male portion has a male portion body that contains an inner slot, an outer slot, and a partition. The belt second distal end passes through the buckle male portion inner slot, around the buckle male portion partition, through the buckle male portion outer slot, around the adjusting ring outer post and is secured therearound. The tube is horizontally positioned at the belt outer surface intermediate the belt first distal end and the belt second distal end and is movable therefrom. The tube removably receives the handle of a golf cart. And, the elastic strip has a first distal end and a second distal end. The elastic strip passes freely through the robe with the elastic strip first distal end and the elastic strip second distal end attached to the belt outer surface so that the tube which removably receives the handle of a golf cart prevents a force encountered by the golf cart from being transmitted to the user.

A follicular unit extraction device comprises a handpiece for holding a follicle punch at its distal end which extends from the handpiece and terminates distally in a cutting edge. The punch is releasably coupled to a motor-driven drive shaft within the handpiece for rotation therewith. A portion of the driveshaft is tubular, and houses a piston that can move towards and away from the punch. An ejector pin is also supported within the tubular portion of the driveshaft distally of the ejector piston and is positioned to move towards the cutting edge of the punch when pushed by the piston. The handpiece and driveshaft have respective fluid inlet ports. The clearance between the piston and driveshaft interior, and the clearance between the ejector pin and punch interior, define a fluid path for conducting fluid entering the handpiece and drive shaft via inlet ports so that the fluid exits the punch at its cutting edge. The clearances limit the quantity of fluid exiting the punch to the small amount needed to protect the follicle to be extracted. Means are provided for selectively increasing the flow rate of the fluid entering the handpiece beyond the limit imposed by said clearances to thereby increase the fluid pressure within the driveshaft, moving the piston distally and, consequently, moving the pin towards the cutting edge of the punch to eject impacted graft or debris. Bias means returns the piston proximally when the flow rate is reduced below the level required to overcome the bias means.

A golf putter comprised of a shaft having an axis, a hosel attached to the shaft and a head attached to the hosel. The head of the putter has a face, a top and a sole. The face of the putter is comprised of multiple facets with a degree of static loft measured from the plane of the facet to the axis of the shaft. It is preferable that there are at least four facets on the face of the putter. The first facet is proximate to the sole of the face and has a first static loft angle. The second facet is above and abuts the first facet and has a second static loft angle which is greater than the first static loft angle. The third facet abutting and above the second facet has a third static loft angle which is greater than the second static loft angle. The fourth facet abuts and is above the third facet and has a fourth static loft angle which is greater than the third static loft angle. It is preferable that the static loft angles of said at least four facets differ by only 1 degree between abutting facets.
