摘要:
The invention provides liquid electrographic toner compositions comprising a liquid carrier having toner particles and at least one soluble polymer dispersed in the liquid carrier. The liquid carrier has a Kauri-Butanol number less than about 30 mL. The toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The soluble polymer is present in an amount of from about 1% to about 10% by weight based on toner particle weight. The absolute difference in Hildebrand solubility parameters between the soluble polymer and the liquid carrier is less than about 3.0 MPa1/2. In one aspect of the invention, the soluble polymer that is incorporated in the toner composition has no more than about 30% weight ratio chemical constitution variance from the chemical constitution of the S material portion of the amphipathic copolymer. In another aspect of the invention, the soluble polymer that is incorporated in the toner composition has no acidic functionality having a pKa greater than 8, and has no basic functionality having a pKa of its conjugate acid that is greater than 8. Methods of making these compositions are also provided.

A low temperature fusing dry electrographic toner composition has a plurality of dry toner particles, wherein the toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The dry electrographic toner composition comprises a volatile plasticizer in an amount effective to reduce the First Heat Exposure Tg by at least about 10° C. as compared to a like electrographic toner composition that does not comprise volatile plasticizer. The plasticizer is sufficiently volatile that the Second Heat Exposure Tg will increase by at least about 5° C. above the First Heat Exposure Tg. Methods of making and of using these compositions are also provided.

The present invention extends to methods, systems, and computer program products for e-mail envelope journaling. A server determines that an entity's (e.g., a recipient revealed form an expanded distribution list) home mailbox store has envelope journaling enabled and specifies a journaling mailbox address. The server sets a journaling property in an e-mail message identifying that the e-mail message is to be journaled. The server adds the journaling mailbox address specified by the entity's home mailbox store to the journaling property. The server sends envelope journaling information through an envelope protocol extension to the journaling mailbox addresses specified in the journaling property. The server sends the e-mail message to one or more recipients specified in the e-mail message and journaling mailbox addresses specified in the journaling property. Journaling servers receiving envelope journaling information, place journaling information in archive messages, and attach portions e-mail messages to archive messages.
摘要:
A process for adhering a coating material to a host particle wherein a blend comprising a coating material and host particles is provided in a coating vessel. The coating vessel comprising the blend is exposed to vibrational force in an amount sufficient to cause the coating material and the host particles to collide with sufficient force to cause the coating material to adhere to the surface of the host particle.

An infusion array ablation apparatus includes an elongated delivery device having a lumen and an infusion array positionable in the lumen. The infusion array includes an RF electrode and at least a first and a second infusion member. Each infusion member has a tissue piercing distal portion and an infusion lumen. At least one of the first or second infusion members is positionable in the elongated delivery device in a compacted state and deployable from the elongated delivery device with curvature in a deployed state. Also, at least one of the first or second infusion members exhibits a changing direction of travel when advanced from the elongated delivery device to a selected tissue site. At least one infusion port is coupled to one of the elongated delivery device, the infusion array, the first infusion member or the second infusion member.

A method of producing a composite image on a final image receptor from image data in a single pass electrophotographic system is provided. The method includes steps for applying liquid transfer assist material comprising charged particles of transfer assist material to at least a portion of an element of the electrophotographic system, along with charged toner particles, in order to provide a composite image layer on a final image receptor in a single pass of a photoreceptive element through transfer of the composite image layer from another element in the system.
摘要:
The invention provides liquid toner compositions in which the polymeric binder is chemically grown in the form of copolymeric binder particles dispersed in a liquid carrier. The polymeric binder includes one amphipathic copolymer comprising one or more S material portions and one or more D material portions, wherein the components of the composition comprise sufficient proton donor and proton acceptor functionality to provide a three dimensional gel of controlled rigidity which can be reversibly reduced to a fluid state by application of energy. The toners as described herein surprisingly provide compositions that are particularly suitable for electrophotographic processes wherein the transfer of the image from the surface of a photoconductor to an intermediate transfer material or directly to a print medium is carried out without film formation on the photoconductor.

A condenser (10) with a return header tank (14) has a receiver tank (22) physically attached along side a return header tank (14). The bottom of receiver tank (22) is closed by an end cap (42) that is attached during the single, high temperature braze process that forms the entire condenser. The desiccant cartridge assembly (24) of the invention has components of a material and design that allow it to be installed within tank (22) before the end cap (42) is attached during the braze process, with no subsequent steps.

Each blow-off valve includes a valve body with a first movable wall defining a portion of the liquid fluid passage therein and a second movable wall defining a portion of the suction fluid passage therein. An actuator interconnects the movable walls for simultaneously moving the walls and opening the fluid passages in response to the electrical leakage-warning signal. In the species of FIGS. 2 and 3, the movable walls are integrally united with the valve body and include frangible sections that are fractured by an explosive squib to separate the movable walls from the body to simultaneously open the liquid and suction fluid passages. In the species of FIG. 5, the movable walls are separate valve elements disposed in a circular bore that opens the passages to the ambient surroundings. The actuator includes a spring, for biasing each of the valve elements out of its respective bore, and a holding device that weakens in response to the electrical leakage-warning signal.
