1 conditions. The ability to easily vary test conditions and the flexibility of
2 presenting test results makes it a valuable research tool for screening a wide
3 variety of lubricant products. Gatto, para. [0065].
4 5. Perez
5 According to Perez, known lubricants subjected to a high temperature
6 environment suffer from severe and rapid thermal and oxidative
7 deterioration. Oxidation of a lubricant produces reaction products which
8 eventually form deposits that are detrimental to oil consumption and engine
9 emissions. Perez, col. 1, ll. 30-35.
10 Antioxidants typically are added to lubricants to combat oxidation.
11 Perez, col. 1, ll. 36-37.
12 The invention disclosed in Perez relates to a liquid composition which
13 can be utilized as a base stock blend for high temperature lubricants and a
14 solid antioxidant additive solubilized for high temperature lubricants. Perez,
15 col. 1, ll. 8-11.
16 Two differential scanning calorimetry methods were used to study
17 oxidation stability. The first was an isothermal method. The second was a
18 programmed temperature method. Perez, col. 9, ll. 1-12.

20 The invention disclosed in McFarland generally relates to methods
21 and apparatus for rapidly screening an array of diverse materials, and in
22 particular, to the combinatorial synthesis and characterization of libraries of
23 diverse materials using IR imaging and spectroscopy techniques.

25 In one embodiment of the invention, the system generally includes a
26 Fourier transform infrared spectrometer. McFarland, col. 15, ll. 65-66.
