Abstract
A vibratory screening machine as described separating solid particles from liquid in which a fine mesh screen (30) includes an inclined region extending upwardly to a discharge edge (34) over which solid material (36) separated by filtration can pass. Vibration of the screen (30) causes the solid particulate material to move towards the discharge edge (34). The screen (30) forms the base of a reservoir having sides (10) and a weir or dam (46) at the opposite end to the discharged edge (34). A suspension of liquid and solid particulate material is supplied to the machine along a pipeline (28) and is discharged onto the rear end of the screen (30) from a discharge head (24). One or more intermediate screens of a similar design are located above the main vibrating screen and above one another and the suspension of liquid and solid material discharged onto the first screen overflows onto the rear end of the screen immediately therebelow. Trays (68) and (70) are provided to catch liquid draining through.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
