Item Montana State College, 1893-1919 : a preliminary sketch(Montana State College, 1943) Burlingame, MerrillThis brief sketch was prepared in 1943 at the time the Montana State College observed its 50th Anniversary. At that time each Department and organization was asked to prepare statement of its historical development, and this outline was prepared to provide information on major events in the early years.Item Physico-chemical studies on the epicuticle of the two-striped grasshopper, Melanoplus bivittatus Say(Montana State University - Bozeman, College of Agriculture, 1949) Chefurka, WilliamItem A study of the consistency of starch gels prepared at a higher altitude(Montana State University - Bozeman, College of Education, Health & Human Development, 1942) Chase, Jean T.Item Effect of iodine on the biochemical and immunochemical properties of the toxic lecithinase of clostridium hemolyticum(Montana State University - Bozeman, College of Letters & Science, 1949) Parmelee, Edwin T.Item The effect of various soil amendments and preceding crops on seedling disease of sugar beets caused by Aphanomyces cochlioides Drechs(Montana State University - Bozeman, College of Agriculture, 1949) Bellingham, Roscoe C.Item The incidence of Diplococcus pneumonia Weichselbaum in a group of individuals at Montana State College(Montana State University - Bozeman, College of Agriculture, 1941) Carter, Elizabeth M.Item Catalytic polyforming of shale oil(Montana State University - Bozeman, College of Engineering, 1949) Crecelius, R.

FrithItem Zero-sequence impedance in single-phase induction motor(Montana State University - Bozeman, College of Engineering, 1948) Chopra, H. C.; Chairperson, Graduate Committee: Nelson, J. A.The purpose of this project was to bring to light more facts regarding the zero-sequence impedance in single-phase induction motors. It had been observed in the laboratory that while a three-phase induction motor (wye-connected and neutral available) is running at certain speed, if we change the connections such that power is applied between one line terminal and the neutral, as shown in Fig. 1, the motor continues to run at one-third the previous speed. This is the customary method of measuring the zero-sequence quantities and forms the basis of this project. In the following pages it has been shown that the zero- sequence impedance definitely exists in the stator circuit, as well as in the rotor circuit of a single phase induction motor. The value of the winding pitch is found to affect to certain extent the actual value of the zero-sequence impedance.
