Title: Method and apparatus for the measurement of colour properties of wet paint
Inventor: COLCLOUGH MICHAEL LEONARD
IPC: G01J3/46
Filed: 1988-07-22
Abstract: Measurement of a colour property of wet paint, such as lightness, by colorimetry or photospectrometry, is carried out on a sample volume contained in a vessel (1) and while or shortly after the sample volume is subjected to shearing forces and advantageously also turbulence. The shearing and turbulence are created by a rotating disc (5) having a spiral rib configuration (7) on one surface which faces a window (4) through which the measurements are made by a spectrophotometer (8). Shearing may alternatively be achieved by passing the wet paint through a tube containing an axially extending stationary shearing member, the tube having a window through which the measurements are made. <IMAGE>
