Abstract: A folder with a clamping device for receiving material in sheet form includes a jacket made of a flat, flexible material. By means of a first indentation configuration, this is divided up into a rear leaf and a backbone part and by means of a second indentation configuration into the backbone part and front leaf. The clamping device is provided in a corner region of the rear leaf, adjacent to the backbone part, so that the material in sheet form, insertable into the folder, is held clamped in the respective corner region by the clamping device. The corner region of the rear leaf wherein the clamping device is provided is delimited with respect to the rear leaf by a first crease and the corner region of the front leaf is delimited with respect to the front leaf by a second crease.

Abstract: A letter file for use in managing papers on a desktop is disclosed. I have many features, which can be made available alone or in combination. The combination structure has a foot element, a staircase base located atop said foot, a detachable paper file trays extending generally vertically from at least some of stairs, a storage element extending from the lowest of said stairs and in front of said file trays, the storage element having a plurality of elongated compartments sized to receive writing instruments or the like, the lower section including a recess and upper and lower rails, slideable storage unit sized to be and a document ledge extending from the lower of rails for holding a document upright in front of the letter file.

Abstract: A re-enterable environmentally sealed enclosure for housing circuitry and/or cable components of a communication network employs a removable cover attached to an enclosure base by a pivoting cam-tracking system. The tracking configuration positions the cover in a manner that, as it approaches the enclosure base when being closed, a seal located in the cover is evenly compressed along its entire perimeter against a corresponding mating surface on the base, thereby distributing the compressive force equally across the entire seal, with any shear forces substantially eliminated. A single tensioning system is provided adjacent the cam-tracking system, so that the tracking system does not operate as a counter-lever to the tensioning system, and visa versa, thereby improving the distribution of force across the seal.

Abstract: An intregal cable retention and sealing apparatus has reusable clamping mechanisms for the entry and exit of a wide variety of cable types and sizes to a sealed enclosure. The device is formed by "mirror-image" body halves having, when assembled, at least one axial passageway formed therethrough to accomodate one or more respective cables. One end of the apparatus includes a chamber for housing a sealing medium, whereas the other end includes a cable retention mechanism.
