RESEARCHES CARRIED ON BY THE ENGINEERING
EXPERIMENT STATION AND THE ENGINEERING
SCHOOLS AND DEPARTMENTS
July 1, 1940, to June 30, 1941
Engineering researches of value to industry are carried on by the Engineering Experiment Station, by the several schools and departments, and by engineering undergraduate and graduate students.
A. Researches of the Engineering Experiment Station include:
(a) Station researches
(b) Co-operative researches — direct with the industry
(c) Co-operative researches — through the Purdue Research Foundation.
B. Researches of the schools and departments include:
(a) Staff researches
(b) Graduate researches
(c) Undergraduate researches.
The report that follows includes brief reports on all active research investigations carried on by the Engineering Experiment Station and by the several engineering schools and departments of Purdue University for the period of July 1, 1940, to June 30, 1941. The reports are grouped under the several divisions of the Engineering Experiment Station, which correspond to the teaching divisions of the schools and departments of engineering.

Researches of the Engineering Experiment Station
Hollow Glass Block Research (Project C-29). Co-operative research for the Owens-Illinois Glass Company, started in July, 1935. Investigators, R. B. Crepps and R. E. Mills.
Purpose. To study the physical and mechanical properties of hollow glass blocks as individual units and also when used for masonry walls.
Progress Report. Modulus of rupture determinations were made on two-block specimens in which different variables are controlled as follows:
1. (a) Glass seal vs. aluminum alloy seal
(b) Different designs of mortar-bearing adhesives
(c) Different weather specimens.
2. Study of different sill coatings. Different series tested as follows: room temperature, freezing temperature, and outside exposure for one year. These tests were to determine the slippage of glass block panels on sills.
3. Expansion-joint materials. Ends and top of glass block panels were studied with respect to amount of compressive movements against applied loads.
4. A 10 x 10 ft. square panel of glass blocks was tested for wind resistance.
5. Reduction of light transmission by exposure to ultra-violet light was studied.
