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.

Abstract: High performance GaAs and AlGaAs-based devices and a process enabling the manufacture of new III-V compound technologies are disclosed.

Abstract: A sheet-like, integral plastic accessory for a notebook is disclosed featuring at least one paper clip sheet. Each paper clip sheet is formed with a frame as defined by a pair of parallel spaced rims and a pair of outer cross rims. A plurality of ribs extend between the parallel spaced rims in parallel spaced relation to one another. A plurality of paper clip configurations extend from the rims and the ribs. Each paper clip configuration is formed with inner and outer elongated bands joined at one end at a nexus. A pair of curved segments define the nexus at one side thereof, with a constricted portion defining the same at an opposed side. Preferably, a pair of shoulders straddle the constricted portion and a burr connects the constricted portion of the paper clip configuration to the rims and the ribs. Preferably, the nexus is wider and stronger adjacent the curved segments than at the constricted portion, allowing the inner band to bend thereat with respect to the outer band without fracture.

Abstract: A therapeutic cold pack is provided for temporary affixation to an area of the human body. The cold pack comprises a pair of hermetic barrier layers that are heat sealed together throughout a plurality of articulations defining a plurality of compartments. A refrigerant gel, such as ethylene glycol, is contained within the compartments and has a high specific heat such that after becoming cooled it absorbs a large quantity of heat while undergoing phase change on heating. The plurality of compartments is distributed throughout an extended area. Adjoining compartments are hinged to each other along intersecting axes. The compartments are adapted to be folded with respect to each other along the axes into a configuration that is snugly seated against an irregular three dimensional anatomical surface. A relatively large velcro-type micro-fastener area is located at the back of the cold pack.
Abstract: A paper punch for use in combination with either a notebook having a pair of covers and a spine therebetween or with a ruler. The paper punch essentially comprises a punching element of unitary construction and formed of a hard yet resilient plastic material, preferably by injection in a mold. The punching element is formed with a pair of parallel spaced arms resiliently connected to one another at one end and featuring male and female punching members respectively disposed on the arms in operative association with each other. A slit is formed in one of the arms in a plane normal to the punching members and bisecting the female punching member. In a normally inoperative position, the male punching member is partially disposed within its cooperative female member in close proximity to the slit, and in an operative position, the male punching member is fully disposed within its cooperative female member, traversing the slit.

Abstract: This invention is a filtration structure characterized by radial fluid flow through the wall of a cylindrical configuration that is established by a stack of serrated annular wafers which are constrained for slight axial movement with respect to each other, for the establishment of two conditions. In one condition, the wafers are axially compressed into snug contact under spring bias to establish a labyrinth of radial passages for fluid flow at a selected pressure. In the other condition, the axial compression of the disks is relieved and the disks are slightly separated by back flushing under an elevated pressure in such a way that cleansing is freely effected by reverse fluid flow.
