摘要:
A method of remediating a media asset comprising a magnetic tape includes preliminarily cleaning the media asset, treating the media asset, and finally cleaning the media asset. Treating the media asset includes baking the media asset, determining whether adjacent layers of the tape are stuck to each other, and re-baking the media asset. If adjacent layers of the tape are stuck to each other, the method includes submerging the magnetic tape in a cleaning bath for a predetermined period of time, unwinding the magnetic tape from a supply reel to a take-up reel at an unwind speed while drying the magnetic tape, and rewinding the magnetic tape onto the supply reel at a rewind speed before re-baking the media asset.

The present invention relates to a method for applying an image to a fabric, which comprises the steps of (i) hand ironing an imaged copier or printer transfer material having a support sheet and a transfer coating to a receptor element having valleys on the surface of the receptor element, (ii) peeling away the support sheet to obtain an imaged receptor element, (ii) placing a tack-free overlay sheet over the imaged receptor element, and (iv) pressing the overlay sheet by hand ironing to drive the coating into the valleys of the receptor element.

The present invention relates to a photographic processing apparatus including a construction for cleaning a magnetic recording portion of a photographic film having such magnetic recording portion. The apparatus includes a transporting mechanism for transporting the film along a film transport passage, a magnetic head for recording magnetic information recorded in the magnetic recording portion, and a stationary head disposed upstream in the film transport passage for cleaning the magnetic recording portion of the film.

The present invention is an imaging element which includes a support, an image forming layer and a backing layer. The backing layer includes a film forming polymeric binder, hard filler particles in an amount of from 10 to 80 volume percent of the backing layer, and crosslinked elastomeric matte beads having a glass transition temperature of 10.degree. C. or less.

This invention relates to a solvent system and process for cleaning cellulose triacetate polymer camera film. The solvent system comprises n-propyl bromide and an alkyl bromide in which the alkyl group contains 4 to 7 carbon atoms.
摘要:
A stabilizing bath that provides image stability and uniform drainage of excess fluid to prevent drying spots and that reduces or eliminates the formation of residue on the base side of color negative films is comprised of hexamethylenetetramine, a nonionic polyethoxylated surfactant, and an anionic sulfate or sulfonate surfactant. The stabilizing bath is used as the final processing bath prior to drying. The nonionic surfactant provides uniform drainage of excess fluid and the anionic sulfate or sulfonate surfactant functions to reduce or eliminate the formation of residue on the base side of color negative films.
摘要:
The self-aligning characteristics of surface-active molecules are used to provide a multiply-coupled thin film surface coating on a substrate, comprising an outermost layer of normally fluid, flexible backbone chain polymer units of at least about 30 atoms in length, the ends of which are attached by chemical bonds to a relatively highly polar second layer of atoms serving to anchor the relatively fluid outer surface layer polymer chains to the surface of the substrate.

CERTAIN MIXTURES OF TETRACHLORODIFLUOROETHANE AND ACETONITRILE ARE USEFUL AS SOLVENTS TO REMOVE ROSIN FLUXES FROM PRINTED CIRCUIT BOARDS. THESE MIXTURES ARE USEFUL BECAUSE OF THEIR UNUSUALLY HIGH SOLVENCY CHARACTERISTICS. A NARROWER CLASS OF SUCH MIXTURES IS PARTICULARLY VALUABLE BECAUSE, IN ADDITION TO HIGH SOLVENCY CHARACTERISTICS, THE MIXTURES EXHIBIT AZEOTROPIC CONSTANT BOILING CHARACTERISTICS, THEREBY FACILITATING HANDLING AND PURIFICATION OF THE SOLVENT MIXTURES WITHOUT SIGNIFICANTLY ALTERING THEIR COMPOSITIONS.
