Alternating-Current Resistance And Inductance Of Single Layer Coils, Clarence N. Hickman

Historical Dissertations & Theses

An integral equation method is used to develop formulas for the alternating-current resistance and inductance of a system of parallel "go and return" circuits. It is shown how these formulas may be applied to single-layer coils. The formulas are applied to several coils in which the "skin effect" is quite pronounced. These coils are measured at several frequencies and the results compared with the computed values. The methods of measurements are explained and a discussion is given pertaining to the distribution of the effective resistance in a coil. The eddy current losses due to dead ends are measured and discussed. …

Bulletin 115 - The Value Of Windmills For Pumping Water In Western Australia, A. H. Scott

Bulletins 1 - 2999

It is surprising to note the dearth of up-to-date reliable information dealing with actual results of modern windmills, under working conditions, though literature on thousands of other subjects less important can usually be obtained.

In this bulletin there is presented a complete and accurate record of the amount of water pumped daily by a windmill, under actual working conditions, for a period of 14 months.

Nebraska Tractor Tests

All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary.

All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University.

Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …

EXPLANATION OF TEST REPORT: Case 40-72

TEST A: The manufacturer's representative operates the tractor for a minimum of 12 hours using light to heavy drawbar loads in each gear.

This serves as a period for limber up, general observation and adjustments. Adjustments that are permissible include valve tappet clearance, breaker ,point gap, spark plug gaps, clutch and others of a similar nature. No new parts or accessories can be installed without having mention made of it in the report. No data' are recorded during this preliminary run except the time that the engine is operated.

The Disintegration Of Refractory Brick By Carbon Monoxide, Wilbur J. Darby

Masters Theses

"In experimental work carried on at East St. Louis, Illinois in 1916 and 1917, with a furnace of commercial size for the electrothermic dry distillation of zinc ores, a difficulty that developed was the destruction of the firebrick lining in certain parts of the large condenser. The condenser was satisfactory in other ways, yielding a large proportion of the zinc as liquid metal, with no blue powder; but in order to obtain a proper length of service from the condenser it became necessary to find and overcome the cause of the disintegration of the lining ... it will be evident …

The Water Supply Of The City Of Milwaukee With Experimental Data, William K. Stumpf

Bachelors’ Theses

All mankind, whether the wandering savage, the isolated pioneer, or the dweller in the congested city, requires a constant supply of water for his needs. This fact is attested to in all the civilizations of the past, and if we go back to biblical times, or to the days of ancient Greece and Rome, we read of the famous wells and aqueducts, from which the inhabitants derived their supplies.

The Middle Ordovician Section In East Central Missouri, Morris James Ingerson, Josiah Bridge

Masters Theses

"One of the most serious difficulties confronting anyone working on stratigraphic problems in the Ozark area is the lack of detailed faunal lists of the various formations. A great deal of general work has been done, but very few detailed faunal studies have ever been published, and correlation of the Missouri section with sections in adjoining states is often difficult.

In a recent paper, Dake has discussed the origin and correlation of the St. Peter sandstone. In this study he found considerable difficulty in correlating the various formations above the St. Peter, and at his suggestion, the present study was …

The Action Of Tan Bark In The Manufacture Of White Lead By The Old Dutch Process, Elmer List

Masters Theses

"This investigation was undertaken because there is very little definite information in print, regarding the micro-organisms which play such an important part in the Old Dutch Process for manufacturing white lead. The statements concerning this process are very general in character. For instance, one book states, "The first action which goes on is to convert blue lead into basic acetate of lead. This is brought about by the heat of the fermenting tan, causing the evolution of acetic acid from the liquid of the pots." Albert H. Hooker in a little treatise on white lead says: "As it stands now, …
