Blood urea nitrogen (BUN) test. Overview. A common blood test, the blood urea nitrogen (BUN) test reveals important information about how well your kidneys and liver are working. A BUN test measures the amount of urea nitrogen that's in your blood. 1  Your liver produces ammonia â which contains nitrogen â after it breaks down proteins used by your body's cells.  The nitrogen combines with other elements, such as carbon, hydrogen and oxygen, to form urea, which is a chemical waste product.
Shortly after the Turner Turnpike was built in 1953, the Oklahoma Turnpike Authority proposed other toll roads including one to be built from Oklahoma City north to the Kansas border near Braman to tie in with the southern terminus of the Kansas Turnpike at the state line.
In 1967 Charles B. Turner, whose family was involved with Palo Pinto Telephone Company in Mineral Wells, Texas, saw the future potential of such an aerial device and approached Howard and Blewett with a partnership offer. Howard accepted and Blewett sold his interest to Turner to stay in the telephone business. Howard and Turner moved to Waco, Texas and officially formed TIME Manufacturing Company in 1968. TIME Manufacturing introduced its first insulated unit, a 28-foot unit, in approximately 1972.
