The Accuracy Of Pressure Gauges Used On Household Steam Pressure Cookers, Arnold E. Baragar

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

In the pressure cooker, high temperature is obtained by using steam under pressure. Since the pressure gauge is used as the indicator of temperature it is essential that the gauge register the correct pressure. Hence, this paper deals mainly with a study of the accuracy of both new and old pressure gauges used on steam pressure cookers. At the same time, four other phases were investigated: (1) the proper functioning of safety valves, (2) the various methods of sealing the lid to the cooker, (3) the proper evacuation of air from the cooker, and (4) the use of a thermometer …

A Critical Analysis Of Methods Of Securing Basic Irrigation Data Used In Water Right Determinations, A. Alvin Bishop

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Agriculture in the Western United States is almost entirely dependent upon irrigation. Irrigation has transformed the desert lands into fertile, producing valleys. It has made possible communities and settlement areas which would otherwise be impossible. Although the achievements of irrigation have been great, there still remains millions of acres of fertile land that will never be reclaimed because there is not available water.

An Approach To County Planning - Miller County, Frederick William Hurd

Professional Degree Theses

"The purpose of this report is to present and discuss a proposed eight year state and county highway program as applicable to Miller County. Local needs for transportation service may be most readily and efficiently administered to on the county basis. The highway requirements of the state are now largely for local service roads and it is evident that a fair and just method of allocating this service must provide for the physical characteristics, economical status and local peculiarities of the area involved. We may therefore justly assume that the counties, the smallest political subdivisions in the state having direct …

How South-West Wisconsin Tailing Piles Can Be Worked At A Profit, Gerald Henry Pett

Professional Degree Theses

"It was not until the Flotation Process was introduced in this S.W. Wisconsin zinc district that the writer was convinced that some of the tailing piles here could be worked at a profit. In 1928, the Badger Zinc Company built a 120 ton Flotation Plant about two miles north-east of Linden. It was after the second visit to the plant that the writer learned the above company was making a profit of a 5% zinc ore with very little lead and with a low market price for the finished product, namely $30.00 per ton for a 60% zinc concentrate...the body …

Design Considerations In Food Irrigation, Hans G. Jepson

Electronic Theses and Dissertations

Flood-irrigation is primarily a system of irrigation which utilizes a part or all of the surface run-off is diverted from contributing watersheds and distributed over the fields by dikes or ditches. Diversion is accomplished through the use of a dam or of dikes if the volume of water diverted is not too great. There are thousands upon thousands of fertile acres throughout the arid and semi-arid regions of the Great Plains which could be materially benefited if bolstered by a little additional rainfall. It is not possible to increase the normal precipitation over the area , but it is possible, …

Conveyor Mining In The Thin Vein Coal Fields At Excelsior, Arkansas, Bernard Degen Boyd

Professional Degree Theses

"From the results obtained after a year and a half of operation using the long face system of conveyor mining in our thin seam of coal, four decided advantages over the old system of room and pillar work with wide rooms have been proven: 1. Operations are concentrated in small sections, thereby permitting larger tonnages to be loaded. 2. One hundred per cent extraction of the vein is obtained (with the exception of main slope pillars) which prolongs the life of the mine. 3. The ventilation of this gaseous vein is simplified. 4. Production costs are reduced"--page 15.

Sinking And Equipping Inclined Shafts Of More Than 60 Degree Dip, Wilford Stillman Wright

Professional Degree Theses

"The advisability of putting down an inclined shaft in preference to the vertical type should be carefully considered before a definite choice is made. One, of course, presupposes the existence of a dipping ore body that is to be prospected or developed for subsequent mining. Unless a vein has been previously developed there is no certainty that it maintains the same degree of pitch for any great distance below surfaces. If straight, the proposed inclined shaft may depart considerably from the downward course of the vein with the result, that, at least some of the anticipated advantages of the shaft …

Professional Degree Theses

"This paper deals primarily with the use of small-scale models in the study of plans for improving the channel for navigation in several reaches of the Middle Mississippi River. However, it was considered expedient to include a discussion of hydraulic model experimentation in general before dealing with specific cases, in order that the reader might obtain the greatest possible satisfaction from the discussion.

The first part of this paper includes: a discussion of the theory of models, wherein the value and utility of models are demonstrated; the application of models to hydraulic problems, including the requirements for a model to …

Hydrography Of The Larger Springs Of The Ozark Region Of Missouri, Warwick Lewis Doll

Professional Degree Theses

"This thesis is based upon a study of the larger springs of the Ozark Region of Missouri and is designed to answer many requests for information about the large springs.

Special studies were made to determine the probable location and approximate area of the drainage areas of the large springs (previous writers have referred to the drainage areas as being “very large" or "enormous", apparently, without any very definite idea as to the extent or the drainage areas). The average run-off per square mile from the assumed drainage area, herein called the "spring factor", was determined for the largest springs. …

The Latouche Mining Method As Used At The Alaska Juneau Gold Mine, Willard Alexander Gallemore

Professional Degree Theses

"The Latouche Mining Method has been used at the Alaska Juneau Gold Mining Company only since 1933, and is used in that part of the mine below the main tramming level. It consists of a series of radiating "long holes" (21 feet) drilled from stope raises, over the back of the stope. These holes break the rock into the stopes, from where it goes through bulldoze chambers to oreways leading to chutes on the No. 10 level. On this level, the ore is drawn into Granby Cars, trammed to the Main Shaft, and hoisted to No. 4 level. On this …

A Comparison Of Methods For The Determination Of Iron In Clays And Related Ceramic Materials, Hoyt Gillum Thompson

Masters Theses

"Iron is always present in clay and ceramic products. This element has a definite effect upon the properties of substances containing it, hence it is important for the ceramist to know the exact amount of this element present in a ceramic material. Many methods have been devised for the precise determination of iron, both in large and small amounts. Of the many methods used, the American Society for Testing Materials has listed only two for the examination of clays, refractories, and similar material...However the amounts of iron for which these methods are most suitable are not given. Nor does the …
