RESEARCHES CARRIED ON BY THE ENGINEERING
EXPERIMENT STATION AND THE ENGINEERING
SCHOOLS AND DEPARTMENTS
July 1, 1941, to June 30, 1942
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, 1941, to June 30, 1942, except certain confidential projects carried on for the War Department. 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. 1. Compressive strength tests of glass blocks have been made to study the relationship between strength and (a) shape and kind of bedding mortars, and (b) weight or wall thickness.
2. Modulus of rupture tests have been made on two-block specimens with a mortar joint between in order to study the effectiveness of variously-fluted bearing surfaces and newer types of adhesive coatings.
3. Expansion "joint materials made of glass fibers and substitute materials have been tested for resistance to compressive loads before and after being subjected to immersion in water and freezing and thawing for twenty cycles.
4. Several panels 10 feet long with heights of 4, 6, 7, and 8 feet have been tested for resistance against wind pressures when the panels contained no horizontal wall reinforcement.
