The presently disclosed embodiments relate in general to electrophotographic imaging members, such as layered photoreceptor structures, and processes for making and using the same. More particularly, the embodiments pertain to an improved photoreceptor that exhibits little to no response to injected charges and demonstrates excellent ghosting properties.

Photoconductors and processes thereof

This method to make an original photoconductor or replacement element uses a two-slot coating process to substantially simultaneously deposit a new SMTL coating layer and a thinner overcoating on an already existing SMTL layer or on a substrate. The total thickness of the existing SMTL layer plus the new SMTL layer plus the overcoating thickness should not exceed the thickness of a belt area of a marking machine or corresponding components in the to be replaced photoconductor element or the tolerances set for said SMTL and overcoating layer when making a new belt.

A method and apparatus control a plurality of sonic sources to generate sound waves within at least one opening of an item. The 'item' can comprise almost anything that has a percolation path (a path where solid particles are to be separated from liquid particles), such as the ground, aggregates, porous structures, porous materials, and a semi-solid structure. By controlling the sonic sources, the method transmits the sound waves to the percolation path. Further, the method regulates the amplitude and frequency of the sound waves such that the liquid particles oscillate out of phase with the solid particles. The method also regulates the phases of the sound waves generated by the different sonic sources so as to control locations within the percolation path where the liquid particles oscillate out of phase with the solid particles.

A filtration system comprising a filter cassette having integrated ultrasonic transducers incorporated therein, and a method for using the same. The integrated system of filters and transducers can be hardened for use in hazardous environments, and is particularly suitable for the implementation of sonication in cross flow filtration processes further integrated with a manufacturing process. The system provides cost savings both in terms of less equipment and space for cleaning processes on the manufacturing floor.

Utilization of non-printing high-spatial-frequency auxiliary pixels are introduced into the bitmap of halftones utilized in an image to obtain local control of the image development by modification of local average voltage in the development nip. These auxiliary pixels embody frequencies or levels of charge that are past the threshold for printing on the Modulation Transfer Function (MTF) curve, and therefore by themselves result in no toner deposition on the resultant page. These auxiliary pixels will however, position the toner cloud by modulating it and compensate for cleaning field and toner supply effects. This will better position the toner cloud to ensure adequate toner supply to all parts of the image so that the desired printing pixels will print as intended and provide a more faithful rendering of grayscale information in the image.

A method and apparatus for dispersal of aggregates of red and white blood cells and platelets. The present invention employs a sonic or ultrasonic device to efficiently breakup aggregates of red and white blood cells and platelets by driving the ultrasonic signal over a small range of frequencies around the acoustic slow wave frequency of the agglomerate. At this frequency, the fluid vibrates out of phase with the solid and is forced out through the pore structure in the agglomerate.

Method for dispersing red and white blood cells

A printing machine for recording an image on a recording medium with marking particles, wherein process of making marking particles includes a method for dispersing pigment aggregates in a solution. The method employs an ultrasonic device to efficiently breakup particle agglomerates by driving the ultrasonic signal over a small range of frequencies around the acoustic slow wave frequency of the saturated agglomerate. At this frequency, the fluid vibrates out of phase with the solid and is forced out through the pore structure in the agglomerate. This relative fluid motion to exert high viscous stresses at the particle-particle contact points which leads to fracture of the agglomerate.
