Abstract: The present invention relates to a method of producing a sodium iron(II)-hexacyanoferrate(II) (Na2-xFe[Fe(CN)6].mH2O), where x is <0.4) material commonly referred to as Prussian White. The method comprises the steps of acid decomposition of Na4Fe(CN)6.10H2O to a powder of Na2-xFe[Fe(CN)6].mH2O, drying and enriching the sodium content in the Na2-xFe[Fe(CN)6].mH2O powder by mixing the powder with a saturated or supersaturated solution of a reducing agent containing sodium in dry solvent under an inert gas. The steps of acid decomposition and enriching the sodium content are performed under non-hydrothermal conditions.

Abstract: A method and system for modular digital watermarking of electronic files is disclosed. The method involves receiving a request for an electronic file, creating a digital watermark, duplicating the file, dividing the duplicate up to produce a plurality of substantially equal sections, and inserting a watermark into each section. The document may be provided to a user. A method for historical analysis of such documents involves scanning a received document to find watermarks, and analyzing the document or watermarks for information concerning the history of the file.

Abstract: An interposer (port selector) and associated systems and methods coupling an SATA storage device to multiple, concurrently operable, storage controllers (multiple initiators). The interposer allows automatic selection of one of a plurality of a storage controllers for active coupling to the corresponding storage device. Features of the interposer and its operation detect automatically which storage controller presently requires coupling to the device and, transparently with respect to both the storage controllers and a storage device, effectuate the desired coupling.

Abstract: A post-fusing apparatus is provided in an electrostatographic reproduction machine for adding a controlled amount of moisture to a side of a fused toner image carrying copy sheet to control curl. The sheet conditioning apparatus includes a moisturizing agent supply and splitting assembly, including a supply source containing moisturizing agent and a plurality of rotatable metering rollers forming at least first and second moisture splitting nips, for splitting a layer of supplied moisturizing agent, and forming a thin film of moisture. The sheet conditioning apparatus also includes a rotatable moisture applying roller forming a moisture splitting and receiving nip with the moisture agent supply and splitting assembly, for receiving the thin film of moisture therefrom.

Abstract: A paper conditioner to control image dependent curl which uses one or more counter-rotating transfer rollers which are initially spaced from their respective back-up rollers in the intercopy gap, and which come together as the lead edge enters the nip area, and separates when the trail edge is about to pass. This permits the rollers to have a less demanding runout tolerance by bringing the rollers together when the sheet is in the nip, and then articulating the rollers apart in the intercopy gap.

Abstract: A vacuum corrugation feeder employs a vacuum feedhead working in conjunction with an air knife to feed sheets from the top or bottom of a stack. A retractable corrugator is included in the vacuum feedhead which prevents smearing of coated sheets due to relative motion between sheet surfaces and the corrugator.

Abstract: A top vacuum corrugation feeder includes articulating suction fingers to assist in raising the top sheet of a stack of sheets to the feedhead of the vacuum corrugation feeder. The suction fingers are rotated down from their interleaved position between feed belts to contact the top sheet in the sheet stack and raises the top sheet to the feed belts. As a result, the feeder can handle heavy sheets, curled sheets, and sheets which are edge welded.

Abstract: A sheet stacking and registration system particularly suited for high speed sequentially stacking of the flimsy printed sheets output of a high speed reproduction apparatus in a sheet stacking area, with a stacking registration position; with a vacuum belt sheet transport system acquiring only a limited lead edge area of the sheets and transporting them over the stacking area with non-slip sheet feeding towards the registration position; and an integral system peeling the lead edges of the sheets off of the vacuum transport and guiding them downwardly and towards the lead edge registration position while reducing but partially maintaining the sheet's vacuum acquisition, and applying a normal force, preferably with a roller pressing down the lead edges of the peeled off sheet against the previously stacked sheets adjacent the registration position, to frictionally slow the sheet as it approaches the registration position, and also holding down the sheet after it reaches the stacking position.

Abstract: A photoreceptor apparatus constructed of a photoreceptor belt releasably attached to the surface of a cylindrical mandrel. The photoreceptor belt is preferably attached to the mandrel by means of a movable segment of the mandrel that is retracted into the mandrel to allow installation of the belt by reducing the effective circumference of the mandrel.

Abstract: An apparatus which adhesively binds a set of sheets by applying a strip having an adhesive to one surface thereof to the spine of the set. The apparatus includes a compiling station which holds at least one set of sheets. A transport advances the set of copy sheets from the compiling station to the bind and to a receiving station. The transport is movable from a non-operative position, coupling the compiling station to the receiving station, to an operative position coupling the compiling station to the binder. In addition, there is a manual insertion station located at the operative position enabling a set of sheets to be inserted into the transport when the transport is positioned in the operative position. The transport is then adapted to advance the manually inserted set of sheets to the binder which then binds the manually inserted set of sheets to one another.

Abstract: A mechanism for shuttering of vacuum ports of a vacuum platen transport (VPT) plenum in correspondence with the size of the documents being transported from the document tray of a recirculating document handler. The shuttering mechanism is coupled to a movable side guide of the document tray and includes a flexible coiled tape mounted with respect to the vacuum plenum of the VPT and movable side guide of the document tray such that movement of the side causes the tape to seal off vacuum slots within the plenum that are not located beneath documents.
