| titleOfInvention | Method and apparatus for the deacidification of library materials |
| abstract | A method and apparatus for deacidification of cellulosic materi- als such as the pages of books, mag- azines, newspapers, documents and the like are provided which ensure that substantially the entirety of each page is treated. The method in- cludes placing the materials within a carrier (64) such that the pages are free for exposure to the treating medium. The carrier (64) is sub- merged in a vat (12) preferably con- taining a dispersion of treating mate- rial including particles of an alkaline metal oxide, hydroxide or salt. The vat (12) includes a support frame (51) which supports the carrier (64) and is slidably mounted on the vat (12) such that the carrier (64) and materials it holds may reciprocate in a generally horizontal direction. The reciprocation of the support frame (51) causes the pages of a book (72), for example, to fan out, and the treating material in the medium thus comes into contact with each page of the book, magazine or other doc- ument. After reciprocating the support frame (51) at a preselected speed and stroke length for a preselected length of time such tha t each page of the book is treated, preferably in its entirety, the carrier (64) is removed from the bath and transferred to a dryer (140). The dryer (140) includes a flexible meshed webbing (142) which is loosely draped over a series of support rods (144) mounted on a frame. The cellulosic materials are placed on the meshed webbing (142) and preheated ai r is passed through the dryer (140) to evaporate any exc ess residual treating medium. |
