A screen decanter for decanting liquid from a reservoir, comprising at least one rack comprising screens and baffles forming the sides of a cavity; a frame attached to the screens and baffles and providing a barrier so that liquid cannot pass from outside into the cavity without passing through the screens; a patterned perforated drain pipe inside the cavity and leading to an opening through which liquids may drain out from the cavity. The pattern of the openings counteracts the hydrostatic head within the rack such that flow through the screens is uniform at all depths of immersion in the liquid reservoir. Preferably, the screens have a porosity of about 50 micrometers.

Method for maximizing uniform effluent flow through a waste water treatment system

A foldable drain pipe for draining effluent from a decanter in a settling tank in a water treatment system, comprising a plurality of pipe sections sealingly connected together end to end by pivotable elbow coupling pairs to form an articulated drain foldable in a vertical direction. The drain pipe is attachable at an upper end to the decanter and at a lower end to a tank outlet in the tank wall. The drain pipe can support its own weight and cannot come into contact undesirably with any other portion of the tank wall. The pipe unfolds upward as needed when the decanter and effluent level are high, and folds compactly between the decanter and the tank outlet when the decanter and effluent level are low. Multiple hobble apparatus options may be selected as defined herein to prevent rotational hyperextension of any of the elbow coupling pairs to assure that the pipe folds correctly.

Screen decanter for screening solids from waste water

A screen decanter for screening solids from waste water in a waste water treatment system comprising a drain manifold and a plurality of cylindrical cartridges mounted to the drain manifold, each of the cylindrical cartridges having an outer screen defining a cavity. Each of the cartridges includes a drain standpipe disposed within the cavity in communication with the drain manifold. Each drain standpipe includes a plurality of patterned openings arranged in at least one row along the length and partial circumference thereof and preferably comprises three rows of patterned openings, each row being disposed at a 120&#xb0; rotational angle from the adjacent row of patterned openings. Each drain standpipe is disposed at a 30&#xb0; rotational angle from its neighbor drain standpipe such that no row of patterned openings in any of said drain standpipes faces directly at any other row of patterned openings in any other drain standpipe.

A digital multimedia presentation appliance is provided having a display for displaying at least one digitized image. The digital multimedia presentation appliance further includes a processor configured to communicate and receive commands, including a digital multimedia presentation appliance print job command, from an external processor capable of executing a software application program for displaying a printing utility. The processor executes a program having instructions for processing the print job command and displaying the at least one digitized image by the display of the digital multimedia presentation appliance. The print job command is transmitted after selection of a digital multimedia presentation appliance printing icon corresponding to the digital multimedia presentation appliance following selection of the printing utility to print the at least one digitized image.

A controls system architecture for an image output terminal (IOT) has a hierarchical structure which isolates subsystem controls for purposes of efficient algorithm design, analysis and implementation. The architecture is preferably divided into three levels and has a controls supervisor which provides subsystem isolation functions and reliability assurance functions. The architecture improves image quality of IOT outputs by controlling the operation of the IOT to ensure that a toner reproduction curve of an output image matches a tone reproduction curve of an input image, despite several uncontrollable variables which change the tone reproduction curve of the output image.

An electrophotographic apparatus having a densitometer, which measures material density located on a substrate by detecting and analyzing only a single diffuse electromagnetic energy signal reflected off of the density of material located on the substrate. Specifically, the apparatus must first be compensated for environmental and individual machine differences using a high density of the material. Moreover, once compensated, the apparatus is calibrated to determine the relationship between diffuse signals and material density. This relationship is calculated by sampling a clean substrate and low densities of the material. Once the relationship is determined, densities of material can be calculated given a corresponding diffuse signal. The calibrated and compensated density calculations enable accurate monitoring and adjustment of the electrophotographic apparatus color toner development systems.

Electrophotographic machine having a method and apparatus for measuring

The present invention relates generally to an electrographic apparatus and more specifically to an improved structural arrangement in electrographic apparatus of the type having a densitometer, which arrangement achieves improved measuring of marking particle density on a photoreceptor or the like. Wherein, use of a charge-coupled device (CCD) allows for a pixel-by-pixel recordation of the photo intensity reflected off of the photoreceptor and toner test patch. Therefore, as a result of the increased sensitivity of the toner measuring, it is possible to measure denser patches of toner, both black as well as color. Thus allowing for accurate monitoring of the amount of toner capable of being placed onto a photoreceptor.

Densitometer and circuitry with improved measuring capabilities of

An electrographic apparatus having a densitometer, which achieves improved measuring of marking particle density on a photoreceptor or the like. The measuring method detects both specular and diffuse light reflected off of the photoreceptor containing marking particles. A compensation ratio is generated from a high density marking particle patch, and is used to compensate the marking particle density to both changing environmental conditions and differences between individual machines. Thus, a more accurate specular signal is calculated which is an accurate indicator of toner density of mass per unit of area concentration. These concentration measures enable accurate adjustments of the electrographic apparatus color toner development systems.

A non-black colored toner DMA sensor arrangement includes a light emitting device for illuminating a toner/surface substrate with light of a wavelength to which colored toners are non-absorbing, and to which the imaging surface is either partially absorbing or transmissive. Light is reflected from the toner predominantly by either scattering or multiple reflections to produce a significant component of diffusely reflected light. A sensor is arranged for detection of the diffusely reflected light, at an angle that does not detect the specularly reflected component of reflected light. An increasing level of diffusely reflected light indicates an increased density of toner coverage per unit area.
