An embodiment using the foregoing queue may have a drawback in that an exclusive access policy may be enforced using an “expensive” locking mechanism in connection with the queue as a shared resource such that only one process may access and manipulate the queue at a time. Additionally, in connection with performing queue management operations, for example, such as adding elements, the complexity of the queue structure may make it difficult to allow more than one process to manipulate to the data structure at any time. One way to enforce this one-at-a-time access is to use a locking technique that allows a process exclusive access to the queue. However, when multiple processors may need to use the cache, then the exclusive access policy may become a bottleneck.
An embodiment having a complex cache management scheme may also have increased traffic within a system. Accordingly, the number of times that a cache lock operation is performed may also increase.
Thus, it may be desirous and advantageous to have a cache management scheme which is efficient and flexible minimizing the costs associated with accessing a cache. The present invention is directed to a carton tester and in particular to a centrifugal carton tester for testing carrier style paperboard cartons of the type used in the beverage industry.
Beverages such as soft drinks and beer are typically sold in bottles or cans which are packaged in carriers in lots of six, eight or twelve bottles or cans to a carrier. The collective weight of these bottles or cans in a carrier when combined with adverse conditions such as a wetting of the carrier and/or rough handling of the carrier can result in a failure of the carrier. Failure of a carrier in the handle region can result in the dropping of the entire carrier. Failure of other portions of a carrier can result in the release of one or more bottles or cans from the carrier. Accordingly, it is important to test such carriers to determine their failure points under various adverse conditions and to make sure the carriers are manufactured to certain standards.
The centrifugal force tester of the present invention has been developed to measure the force required to produce failure in a package designed to hold and support a relatively heavy product. It is primarily designed to test the carriers commonly used in the soft drink and beer beverage markets to carry multiple units of bottled or

 An shape using the waive queue may have a drawback in that an single entree policy may be enforced using an “ expensive ” locking mechanism in connection with the queue as a shared resource such that entirely one process may access and manipulate the queue at a fourth dimension. Additionally, in association with performing queue management operations, for example, such as adding elements, the complexity of the queue social organization may make it difficult to allow more than one summons to manipulate to the data social organization at any time. One means to enforce this one - at - a - time entree is to use a locking technique that allows a process single access to the queue. However, when multiple processors may need to use the cache, then the exclusive access policy may become a bottleneck. 
 An embodiment having a complex cache management scheme may also have increased traffic within a system. Accordingly, the act of times that a cache lock mathematical process is perform may also increase. 
 Thus, it may be desirous and advantageous to have a hoard management scheme which is effective and flexible minimizing the costs consociate with accessing a cache. The present invention is directed to a carton tester and in particular to a centrifugal carton tester for testing carrier style paperboard cartons of the type use in the beverage diligence. 
 beverage such as cushy drinks and beer are typically sold in bottles or toilet which are packaged in carriers in lots of six, eight or twelve bottles or cans to a carrier. The collective weight of these bottle or cans in a carrier when unite with adverse conditions such as a leak of the carrier and/or rough handling of the carrier can leave in a failure of the carrier. Failure of a mailman in the handle area can result in the dropping of the entire carrier. bankruptcy of other portions of a carrier can result in the liberation of one or more bottles or cans from the carrier. consequently, it is important to test such carriers to determine their failure points under various adverse condition and to make sure the carriers are manufactured to certain standards.
