HENRY T. SAMPSON - Inventor of Gamma Electric Cell
Dr. Henry T. Sampson has been mistakenly noted as the inventor of the cellular phone. According to Dr. Sampson, the Gamma Electric Cell, patented July 6, 1971, Patent No. 3,591,860 produces stable high-voltage output and current to detect radiation in the ground.
Dr. Henry T. Sampson, Ph.D. nuclear engineer, graduated from Lanier High School in Jackson, Mississippi in 1951. He attended Morehouse College for two years, transferred to Purdue University and graduated with a B.S. Degree in Chemical Engineering. He worked as a research chemical engineer at the U.S. Naval Weapons Center, China Lake, California, in the area of high energy solid propellants and case bonding materials for solid rocket motors. He earned a M.S. Degree in engineering from UCLA in 1961 and pursued another MS Degree in nuclear engineering in 1967 earning a Ph.D. in the same field of study. Dr. Sampson co-invented and co-patented the gamma electric cell in 1968 which produced stable high voltage output and current. He also holds three patents concerning solid rocket motors and one on the direct conversion of nuclear energy into electricity. He has written over ten (10) technical papers in rocket propulsion, direct conversion of nuclear energy to electricity and computer simulation of electrical systems.

TYPE-WRITING MACHINE by Lee S. Burridge and Newman B. Marshman invented new and useful improvements in typewriters.
The object of this invention is to provide an inexpensive and yet compete typewriter with very few parts, not liable to get out of order, requiring for its operation as few movements as in the case of expensive machines now in use, and which will admit of printing a sheet of paper of any length without the necessity of coiling or folding the same length.
