A decoration means () for retainers of collapsible tubes and bags. A user of a toothpaste or similar tube will normally progressively coil, lap or fold the bottom end of the tube as the contents of the tube is used. The user of a plastic or other collapsible bag will normally progressive coil, lap or fold the open end of the bag as the contents is used. The retainer device is attached to the coils, laps or folds of the tube or bag, holding them firmly in place, thereby preventing any uncoiling, un-lapping, or unfolding. The current invention provides a means () to add decoration () to the retaining device and, in some cases, change the decoration () and ().

A method of and apparatus for encoding computer program instructions and data greatly reduces the total storage requirements. Upon compiling each computer program segment, statistics are generated regarding the frequency of use of each unique program operator and each unique program operand. The operators and operands are encoded using the information theoretic encoding technique. A conversion table is also prepared which enables the object computer to translate the encoded operands and operators during that time when the computer program segment is being executed. Apparatus within the object computer decodes the encoded operands and operators using the conversion tables enabling execution of the computer program segment.

Conceptual structures which can be used to represent any knowledge that can be represented by frames/units. Its realization, in a software program called Unit Interface, provides a method of storing frame/unit data in conceptual structures and algorithms for accessing that data when stored in conceptual structures as if it were a frame/unit or collection of them.

A memory for storing a directed acyclic graph (DAG) for access by an application being executed by one or more processors of a computing device is described. The DAG includes a plurality of nodes, wherein each node represents a data point within the DAG. The DAG further includes a plurality of directional edges. Each directional edge connects a pair of the nodes and represents a covering-covered relationship between two nodes. Each node comprises a subgraph consisting of the respective node and all other nodes reachable via a covering path that comprises a sequence of covering and covered nodes. Each node comprises a set of node parameters including at least an identifier and an address range. Each node and the legal address specify a cover path. Utilizing DAG Path Addressing with bindings the memory can be organized to store a generalization hierarchy of logical propositions.
