United States Patent: Antenna Strain Insulator, Robert Katz Jan 1948

United States Patent: Antenna Strain Insulator, Robert Katz

Robert Katz Publications

The invention to be hereinafter described relates to insulators and more particularly to strain insulators for wire antennas.

It has long been common practice to use with antenna wires on airplanes the well known porcelain or ceramic insulator, the wire ends being looped through or about the insulator, and brought back and twisted about the wire to tie, anchor or securely attach or fasten the insulator to the antenna. The produces small wire-end surfaces or other small wire surfaces, where the wires are would or twisted, which under certain atmospheric conditions are favorable to corona discharges. When the corona discharge …

Interim Report On The Florida Crawfish Investigation., Marine Laboratory Jan 1948

Interim Report On The Florida Crawfish Investigation., Marine Laboratory

RSMAS Technical Reports

During 1944-1945 the volume of lobsters landed in the spiny lobsters industry decreased to about one half of the 1943 volume and to little more than one third of the amound landed during 1941, which was the year of peak production. Since it was suggested that the cause of this might be overfishing, the University of Miami Marine Laboratory was invited to carry out an investigation in co-operation with the United States Fish and Wildlife Service and the Florida State Board of Conservation.

A New Sciurid Of Blancan Age From Kansas And Nebraska, Claude W. Hibbard Jan 1948

A New Sciurid Of Blancan Age From Kansas And Nebraska, Claude W. Hibbard

Bulletin of the University of Nebraska State Museum

The collecting of vetebrate fossils from deposits of Blancan age in Kansas, Nebraska, and Texas during the past twelve years has revealed many interesting forms. Some species have been found to have wide geographic distribution. A large sciurid related to the woodchucks has been recognized from both Kansas and Nebraska and is here described as a new genus and species.

Geology 63: Geological Report Of Senior Field Trip, Thomas L. Wilson

Bachelors Theses and Reports, 1928 - 1970

The field work was conducted in areas adjacent to White­hall, Montana, as has been the custom for the past several years. Instruction in the proper use of the telescopic and open sight alidades, and the Brunton compass for surveying geologic features was given. Advantages of pacing and speed­ometer mapping were pointed out and used.

Test 399: Allis-Chalmers "Wd", Nebraska Tractor Test Lab

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 …

Progress Report On The Ground-Water Hydrology Of The Republican And Frenchman River Valleys, With A Section On The Chemical Quality Of The Ground Water, Herbert A. Waite, Herbert A. Swenson Jan 1948

Progress Report On The Ground-Water Hydrology Of The Republican And Frenchman River Valleys, With A Section On The Chemical Quality Of The Ground Water, Herbert A. Waite, Herbert A. Swenson

United States Geological Survey: Water Reports and Publications

Abstract for first section

This report is based on current investigations of the groundwater resources of the Republican and Frenchman River Valleys in Nebraska and includes data gathered to December 31, 1947. These studies vere started late in 1945 as a part of a program of groundwater investigations now in progress in connection with the Missouri River basin development plan. Studies to date have consisted principally of periodic observations of water table fluctuations at selected observation wells, of collection of samples of groundwater for chemical analysis, and of collection of data concerning the municipal water supplies in the valley. In …


Geology Of The Berryman Area, Washington County, Missouri, Jack Alexander James Jan 1948

Geology Of The Berryman Area, Washington County, Missouri, Jack Alexander James

Masters Theses

"Purpose and scope - The are discussed in this thesis was selected because of recent exploration for lead within this region and because of the need for more detailed information of the structure and geologic history of the area. The work constitutes part of a program of geologic mapping by the Missouri Geological Survey and Water Resources to complete the mapping of a strip of quadrangles extending across the Ozark Uplift from Rolla eastward to the Mississippi River"--Introduction, page 1.


The Effect Of Metallic Fluorides On Oleic Acid At Elevated Temperatures, Lorraine W. Dupuis Jan 1948

The Effect Of Metallic Fluorides On Oleic Acid At Elevated Temperatures, Lorraine W. Dupuis

Bachelors’ Theses

The problem of finding the effect of metallic fluorine compounds on oleic acid at elevated temperatures was presented in connection with the thesis of J.J. Wocasek of Marquette University. Doctor Wocasek had used fluorine compounds as catalysts in a.n attempt to find a sub­stitute for tung oil. He used the fluorides as catalysts in the esterification of glycerol with unsaturated acids.


The Kerr Electro-Optic Effect In Plastic Materials Transmitting Infra-Red Radiation, James Edson Dueker Jan 1948

The Kerr Electro-Optic Effect In Plastic Materials Transmitting Infra-Red Radiation, James Edson Dueker

Masters Theses

"Much work has been done investigating the Kerr Electro-Optic effect and what physical properties of a substance lead to the occurrence of the phenomenon. Information now available indicates a relationship between molecular shape and orientation with the Kerr Effect, hence any added information increases the possibility for finding the exact relationship and the molecular structure of substances. The Kerr Effect, has been used in a number of applications other than for the study of molecular construction of matter. Many applications have been made to form Electro-Optic shutters. This field of work has been increased to include light flash production and …
