258 (CCPA 1962).
The coating apparatus shown in Fujisawa and Appellants’
Fig. 1 show remarkable similarities. Each employs three
reservoirs (one for the coating composition and two for
additives), a sensing means which regulates the flow of
material from the reservoirs, a means for mixing the materials
from the reservoirs and a means for spraying the adjusted
coating composition. Fujisawa teaches the concept of
controlling the viscosity of a coating composition by
measuring the temperature in coating booth 13, using the
temperature measurement to control the flow rates of the
coating composition from the reservoir 1 and solvent from
reservoirs 2 and 3, mixing the coating composition and
additional solvent in mixer 18 to obtain an adjusted
formulation of the coating composition having the desired
viscosity, and then spraying the adjusted composition onto a
substrate in the spray area (abstract; col. 2, lines 35-42;
and col. 3, lines 15-68). The teaching of Fujisawa is not
limited to any particular coating material. Therefore, it
