With the onset of World War II, Hammett took a leave of absence from Columbia to become first associate director and later director of the National Defense Research Committee s Explosives Research Laboratory in Bruceton, Pennsylvania, just outside Pittsburgh. During his tenure, the laboratory made a number of important inventions that contributed to the success of the war effort. After the war, Hammett returned to Columbia, where he remained until his retirement in 1961. He spent the last 25 years of his life in the Quaker retirement community of Medford Leas, New Jersey, where he died on February 9,1987. 

B) Drop Weight Impact Test used at LASL is a modified version of machine developed by E.H. Eyster R.F. Davis at the Explosives Research Laboratory, Bruceton, Pa and described in OSRD 5744(1945). The apparatus is known as "ERL Machine . 

About 1943, a simplified method for ealen of deton velocities of solid organic expls was developed at the Explosives Research.Laboratory (ERL), Bruceton, Pennsylvania. As there was no report issued at that time but just an unpublished letter of E.M. Boggs F.J. Martin addressed to Brinkley, a brief description of the method was given by him in Ref 39, p 87 In the ERL method, the general equation of state (See our eq 23), with a single covolume constant per unit mass of gaseous expln product, was used and the decompn scheme which leads to quantitative formation of water,... 

Brief mention of impact machines is made under Physical Tests in Vol 1, p XVII. Because there are many literature references to the following impact machines, and not because they are inherently better than any others, we will now describe the following Explosives Research Laboratory (ERL), Rotter, Bureau of Mines (BOM) Picatinny Arsenal (PicnArsn)... 

Explosive Streamers. The design of continuous TNT charges for Mark 29 streamers, carried out at the Explosives Research Laboratory, Bniceton, Pennsylvania, has led to the development of the Flexed TNT Charges.

ERL Polar PE. An American plastic explosive developed by the Explosives Research Laboratory, Bruceton, Pa. It consisted of RDX (50-70% thru 30 retained on 200 US Std Sieve and 30-50% thru a 200 US Std Sieve) 88% and Gulf Crown Oil E or Gulf 300 Process Oil [(95%) + Lecithin (5%)1 12%. Its properties resembled the British PE No 2, but possessed improved low temperature behavior...

This accident caused a re-investigation of the explosive properties of ammonium nitrate mixed with fuel oil. A considerable amount of work was done by several authors particularly in the Explosives Research Laboratories, U.S. Bureau of Mines. 

The possibility of using cal. 50 bullets for some expls which cannot be detonated or are difficult to detonate with cal. 30 bullets was investigated during WWII at the Explosive Research Laboratory, Bruceton, Pa. Results of this investigation were reported in Ref 4,pp 14-16...
