The structure of the present invention comprises an index file in the form of a shiftable table longitudinally operable upon a support base. The table is shiftable upon antifriction means, and may be releasably locked in position. Means is provided for sectionalizing the index cards or data folders carried by the table to maximize accessibility and minimize operator fatigue.

A file handle for files of the type having teeth stroke out of a relatively thin metal plate with the plate having U-shaped reverted attaching flanges at the opposite ends thereof. The handle includes an elongate metal bar body having a downwardly sloped outer end for engaging in one of the flanges of the file. The bar has an upstanding portion extending at right angles to the body carrying a handle on its upper end extending at right angles to the upstanding portion so as to be generally parall...

A structure manufactured from a single flat sheet of material which may be folded together into a relatively small, compact packaged configuration for transportation and storage, and assembled together into a convertible box-tub configuration. In the box configuration the structure is generally rectangular. In the tub configuration the sides are splayed outwardly so as to permit easy access to the contents in the interior of the structure.

Clips for temporarily holding a memo or note on a surface. The clip comprises an elongated strip of semi-rigid resilient sheet material having a lip along one longitudinal edge and a longitudinal strip of adhesive parallel to and spaced from the lip. In the preferred form of the clip, the lip is upturned and the adhesive is applied to the opposite surface of the strip. The clips may be formed from plastic or paperboard sheet material. Where the clips are provided separately from the surface to w...

Disclosed is a device for holding a conventional file either in the vertical (on edge) or in a horizontally flat position. It is composed of two symmetrical body members having front and rear panels and an upper surface extending into a margin disposing a linear recess for approximately one half its length and a protruding linear finger along the balance of the margin. Each body member has a stepped recess in its front and rear panels. As such, when the two symmetrical body portions are placed i...

An adaptive method of file compression is based on the recognition that language can be thought of as a stream of alternating words and separators. Empty dictionaries are created for the words and separators. For each event in the data stream, a determination is made whether the word is in the dictionary for words compiled from the previously encountered words or whether the word is a new word. If the event is a separator, a similar determination is made using the dictionary for separators. If t...

A file device includes a plurality of vertically stacked drawers or shelves provided with a safety interlock system precluding the opening of more than one storage element at a time. The cabinet contains a plurality of vertically aligned lock bars supporting rotary cam members adapted to be arcuately displaced upon movement of one storage element whereby all remaining lock bars and cam members are immobilized against vertical and rotary displacement respectively, to block movement of any additio...

A card file having a rotor with radiating arms, each of which has a card-carrying tray detachably connected thereto. The rotor is mounted in a housing for rotation about a horizontal axis so that each tray can be brought to a detent-defined viewing position at which the tray is disposed in a substantially horizontal attitude affording ready access to the file cards carried thereby. Inwardly facing ribs on the lower portion of the housing have their edges concentric to the axis of the rotor to be...

An endless belt is mounted on, and extends between, a pair of elongated rollers rotatably mounted in a housing in spaced parallel relation parallel to, and in proximity with, the top and bottom of the housing. A plurality of shelf members are affixed to the belt and extend perpendicularly from the belt in spaced parallel relation for releasably storing files between next-adjacent shelf members. A motor coupled to one of the rollers rotates the rollers and the belt to move the shelf members cycli...

An endodontic file is provided for use in root canal procedures. The file has an elongated blade with cutting edges formed on the lower portion thereof and having a shank at its upper portion. A file head is provided having a passageway formed therein which receives the shank of the blade. The end of the shank is flared to prevent the shank from being drawn through the passageway in one direction. By anchoring the file blade in this manner, the use of a low profile handpiece is facilitated for e...
