Class Information
Number: 494/56
Name: Imperforate bowl: centrifugal separators > Rotatable bowl > Including discharge-related structure in nature of (a) outlet having device for controlling quantity of flow, (b) element associated with pickup of material and adjustable for varying quality of flow, or (c) static scraper or the like for engaging material in moving bowl
Description: Apparatus which includes structure that is involved in either the preparation for departure, of the departure, or both, of material from the member and which structure takes the form of (a) an exit passage which includes a valve or like device for varying the amount of material moving through the passage, or (b) an element which is related to the gathering of material that is to be conducted out of the member and which element is repositionable or otherwise adjustable for changing the ratio of the lighter component or components to the heavier component or components in the material gathered, or (c) a blade or similar abutment which, except for purposes of repositioning, is stationary relative to a member which is turning about its axis and serves to dislodge (e.g., peel off) material being moved against it by the member.
