Abstract: A structured fluid composition comprising: (a) a low refractive index liquid; (b) particles including light absorbing charged particles such as pigments, non-light absorbing uncharged particles such as teflon, silica, alumina and combinations thereof; and (c) at least one additive selected from the group consisting of a dispersant, a charging agent, a surfactant, a flocculating agent, a polymer, and combination thereof; for use in a TIR electronic display. The inventive composition improves the long-term stability, response time and visible appearance of image displays which electrophoretically frustrate total internal reflection (TIR).

Abstract: A process for separating a hydrophobic hydrocarbon chemical from an aqueous emulsion and recycling the majority of the water, co-solvents, salts, and the emulsifier is set forth. A preferred emulsifier is a salt of a carboxylic acid, phosphoric acid or sulfonic acid having an amine in the hydrophobic portion of the emulsifier, said amine being capable of being protonated to change (increase) the water solubility of the entire emulsifier molecule. The process is useful for soil remediation by extraction in that it facilitates the recycling of the water and emulsifier dramatically reducing the amount of water and emulsifier used in remediating a site. A method for remediating contaminated soil using the process is also set forth.

Abstract: Soil, which is contaminated by one or more hydrophobic organic chemicals, can be cleaned or remediated using an aqueous composition with a surfactant prepared by reacting an alkenylsuccinic anhydride or acid with an amine acid or salt of an amine acid. The surfactant allows at least a portion of the hydrophobic organic chemical to be removed from the soil by becoming associated with the aqueous composition, which is then separated from the soil.

Abstract: An ink for ink jet printing includes a liquid vehicle comprising water and toner particles with a colorant dispersed in or associated with the toner particles. The ink composition combines the print quality advantages of xerographic printing with the economic advantages of ink jet printing, thereby providing waterfast, archival quality prints.

Abstract: A portable, lightweight, dual-lighted clamp having two jaws for gripping a variety of objects and a pair of battery-operated flashlights assemblies integrally built into the handles, with the light bulbs and transparent illuminating areas located at each of the jaws. The spring clamp may be conveniently attached to many hard-to-reach places. The flashlights each have a switch actuator for allowing the user to easily operate each flashlight.

Abstract: An electrophotographic imaging member comprising a substrate, a ground plane layer comprising a titanium metal layer contiguous to the substrate, a charge blocking layer contiguous to the titanium layer, a charge generating binder layer and a charge transport layer. This photoreceptor may be prepared by providing a substrate in a vacuum zone, sputtering a layer of titanium metal on the substrate in the absence of oxygen to deposit a titanium metal layer, applying a charge blocking layer, applying a charge generating binder layer and applying a charge charge transport layer. If desired, an adhesive layer may be interposed between the charge blocking layer and the photoconductive insulating layer.

The device comprises:(a) an electrically conductive substrate;(b) a layer of material capable of injecting holes into a layer on its surface;(c) a hole transport layer in operative contact with the layer of hole injecting material which transport layer comprises a combination of a highly insulating organic resin having dispersed therein small molecules of an electrically active material, the combination of which is substantially non-absorbing to visible light but allows injection of photogenerated holes fom a charge generator layer in contact with said hole transport layer and electrically induced holes from the layer of injecting material;(d) a layer of a charge generating photoconductive material on and in operative contact with the charge transport layer; and(e) a layer of an insulating organic resin overlaying the layer of charge generating material.

Abstract: This apparatus comprises a supporting frame for two upstanding chutes though which flowable, particulate materials may be applied. These materials flow down the chutes though an opening in the top skirt plate supported by the frame and into a processing area such as the rotor of a centrifugal impact milling machine. A motor is mounted for horizontal pivotal movement relative to the chutes and drives a vertical spindle located between the chutes that is connected to the rotary processing member below the skirt such as the rotor of a centrifugal impact machine. A hopper is provided to swing pivotally downward below the rotor in a damped fashion, the pivoting mechanism being fixed to the top skirt and enabling one man removability of the hopper to allow access to the rotor or the inside of the hopper for cleaning, maintenance, etc.

Abstract: A photoreceptor used in xerographic imaging process and normally including a photoconductive layer comprising a mixture of photoconductive particles dispersed throughout the layer with resinous binder material is joined by bonding to a conductive base layer through an intermediate layer which provides a charge carrier injecting interface between the photoconductive particles and the base layer. The charge carrier interface is obtained by forming the intermediate layer from high mass conductive particles dispersed within an insulating resinous material, and causing photoconductive particles in the photoconductor layer to contact conductive particles in the intermediate layer along the bond interface. The conductive particles are selected so as to have available charge carriers at suitable energy levels whereby the photoconductor to conductor particle contact points form individual charge carrier injection contacts which permit certain xerographic imaging processes to be used.

Abstract: A biased roller electrostatographic image transfer system in which the image transfer fields are generated by a biased conductive member inside the roller and tailored by a partially surrounding stationary conductive shield which is also inside the roller. The shield extends over the pre-nip area to suppress undesired pre-nip transfer fields, but is apertured in the nip area to allow a high transfer field to be applied therethrough the shield.
