Number: 494/36
Name: Imperforate bowl: centrifugal separators > With means for filtering
Description: Apparatus provided with means for removing an undesired or unintended constituent (e.g., particles of a solid) from material which is enroute to, or within, or enroute from, a separator, and wherein the means is a medium of a porous or perforate nature which is placed in the flow path of the material and prevents the constituent from continuing to accompany the remainder of the material.
