Abstract: A paper punch for punching one or more holes into one or more sheets is disclosed. The paper punch includes a pair of top and bottom plates, formed of a polymer and hingelike mounted to one another along respective straight edges about an off-center pivot point located below the surface of the bottom plate. The off-center hingelike mounting assures an equal tolerance in entry as the punch head enters its punch hole. The hingelike mounting further includes integral mounting members designed to secure the paper punch about rings of a loose-leaf binder. The hingelike mounting includes male members formed on one of the pair of plates designed to cooperate with female members formed on the other plate. One of the pair of plates is formed with a reentrant segment to facilitate the angular separation of said pair of plates from one another preparatory to insertion of a sheet therebetween. The pivot is off-centered by a distance equal to the height of a male punching member.

Abstract: Data storage space and data access time are significantly decreased by utilizing a tree structure to store data in memory. Only one copy of each data element common to different data units is stored. Each data element is stored in a node that has a next pointer and an alternate pointer. The next pointer points to a list of alternatives for the next sequential element of the data unit. The alternate pointer defines that list of alternatives. Thus, a progression of next pointers and alternate pointers corresponds to a unique data unit. Associated with each data unit is one or more identifiers, which tie the data unit to data units in another trees or to external objects. The last alternate pointer in an alternative list points back to the preceding element of the data unit in order to reconstruct a data unit from the identifier. Nodes in memory that are not currently being used in the tree are linked together to form a list of free nodes.
