Abstract: A self-cleaning system for a plate press (100) or cylinder press (110) for filtering a fluid product and for eliminating waste material accumulated on filter membranes (13) in a waste accumulation area (102) of the plate press (100) or cylinder press (110), said system comprising a drain port (DP) adjacent to the waste accumulation area (102), said system comprising an area (103) creating a circulation of water and/or forced air jets within the waste accumulation area (102) to expel the waste to the drain port (DP), whereby the waste accumulation area (102) is cleaned from the waste material without having to disassemble the plate press or cylinder press.

Abstract: A method of presenting to a user a subset of digital goods that may be executed by a computing device is disclosed, where the subset of applications is selected from a plurality of digital goods available in an online marketplace for such digital goods. The method includes ranking the digital goods based on at least one signal, statistically sampling the ranked digital goods based on their rankings, where higher-ranked digital goods are favored over lower-ranked digital goods in the statistical sampling, and presenting the statistically sampled digital goods in the online marketplace to the user in an order based on the statistical sampling, where at least one lower-ranked digital good is presented before a higher-ranked digital good.
