摘要： An apparatus including a read head and at least two tape guides. The read head detects a magnetic field representative of information recorded on magnetic tape media, and the at least two tape guides guide the magnetic tape media on a path adjacent a read surface of the read head. The at least two tape guides are positioned to contact a substrate of the magnetic tape media and to maintain a non-zero distance between the path and the read surface.

摘要： An improved method of deacidifying books, imaged paper and other imaged materials having a cellulose base wherein, for a sufficient time to raise the pH of the materials, the materials are treated with alkaline particles of a basic metal oxide, hydroxide or salt dispersed in a hydrofluorether carrier, alone, or in combination with a perfluorinated carrier. A surfactant is added.

摘要： A method and apparatus are provided for deacidifying cellulose based materials, especially books, magazines, and other bound or folded cellulose materials having a spine. The method includes contacting the materials with a treating medium and producing relative movement at a predetermined velocity between the materials and the treating medium in a direction generally parallel to the spine of the materials and, preferably simultaneously, directing the treating medium by means of a spray toward the materials in a direction generally perpendicular to the spine of the material for a period of time effective for the treating medium to contact substantially all of the material. Following treatment, any excess treating medium is removed from the material and directing any such removed treating medium to a holding tank for reuse later. The movement in a parallel direction is achieved by reciprocating the materials through a tank filled with treating medium. In addition, the materials may be rotated about a central axis of the treatment tank. The preferred embodiment of the present invention includes an apparatus consisting of a treating tank for containing the treating medium, a plurality of material holders disposed in the tank on a reciprocatable and rotatable shaft, and spray nozzles for producing the perpendicular movement of the treating medium relative to the spine of the material.

摘要： A method for temporarily revealing the presence of a watermark on cellulose-based materials. The method comprises applying one of a perfluorocarbon ard hydrofluorocarbon to at least a portion of the cellulose-based material. The method also provides applying a solution containing both perfluorocarbon and hydrofluorocarbon to the cellulose-based material to vary the rate of evaporation of the solution.
