Appeal No. 2007-0495
Application No. 10/699,510
The metering apparatus 201, 203, and 205 are each automatically controlled by
control system 250 which preferably includes a microprocessor (specification, p. 19, lines
8-11).
The appellants define “program control” as meaning that the equipment used to
provide the plurality of lubricating oil compositions is automated and controlled by a
microprocessor or other computer control device (specification, p. 5, lines 4-7).
Kolosov discloses systems and methods for screening a library of material
samples for a rheological property such as viscosity (abstract).
Kolosov discloses that the invention may be used to screen or test flowable
materials such as lubricants (p. 4, para. 42).
The invention disclosed in Kolosov has particular utility in connection with the
screening of a number of different material forms including oils (p. 4, para. 43).
The Kolosov invention can be used to analyze the resulting properties of a
particular flowable sample material or the relative or comparative effects that an additive
has upon a particular flowable sample material, e.g., the effective of a detergent, a flow
modifier, or the like (p. 4, para. 43).
An additive is defined as any substance incorporated into a base material, usually
in low concentrations, to perform a specific function, e.g., antioxidants, stabilizers,
preservatives, dispersing agents, viscosity-index improvers, etc. The Condensed
Chemical Dictionary, 20 (10th ed. 1981).
According to the invention of Kolosov, a plurality of samples may be employed.
For example, four samples may be employed, one control sample and three varied
