Electronic Three-Phase Wave Generator, Don Cronin Jan 1959

Electronic Three-Phase Wave Generator, Don Cronin

Mechanical and Aerospace Engineering Faculty Research & Creative Works

The present invention relates to electric signal generators, and more particularly to an electronic three-phase Wave generator.


Generator Control System Employing Semiconductor Apparatus, Don Cronin Jan 1959

Generator Control System Employing Semiconductor Apparatus, Don Cronin

Mechanical and Aerospace Engineering Faculty Research & Creative Works

This invention relates generally to new and improved transistor control apparatus for controlling the excitation of rotary generators. In the field of transistor control of generators, especially where it is desired to control relatively large field excitation currents, the problem arises of obtaining suitable transistors having a sufficiently large current carrying capacity to properly control the current flowing in the generator exciting field. It has been found that the answer does not lie in paralleling two or more transistors directly, since only by extremely carefully matching of transistors or by utilizing auxiliary electronic components in the circuit can it be ...


Unsteady State Heat Transfer From A Hot Body To A Liquid, Larry Clinton Atha Jan 1959

Unsteady State Heat Transfer From A Hot Body To A Liquid, Larry Clinton Atha

Masters Theses

"The problem investigated in this thesis is that of unsteady state heat transfer from a hot body to a liquid, a quenching problem. Unsteady state or transient heat transfer is heat transfer in which the temperature distribution changes with time.

If a hot body was suddenly quenched in a large mass of liquid, a film of vapor would form between the hot body and the liquid. For example, if a hot body was quenched in water a film of steam would form between the hot body and the water. It is the purpose of this thesis to determine the heat ...


Stability Of Rectangular Plates By Arbitrary Deflection Method, James Arthur Jones Jan 1959

Stability Of Rectangular Plates By Arbitrary Deflection Method, James Arthur Jones

Masters Theses

"Many engineering structures use thin rectangular plates as members. These plates may be loaded and supported in numerous ways. The edges may be freely supported, rigidly supported, or supported by elastic members. The load may be applied normal to the plane of the plate, in which case the problem becomes essentially one of bending. If the load is applied in the plane of the plate, placing it in compression, the problem becomes one of stability.

This investigation is concerned with the stability of plates rigidly supported on all edges and having a compressive load applied to two opposite edges of ...


Bonded Joint Strength Versus Loading Rate, Charless William Fowlkes Jan 1959

Bonded Joint Strength Versus Loading Rate, Charless William Fowlkes

Masters Theses

"The purpose of this investigation was to determine the influence of the rate of loading variable on the apparent shear strengths of joints bonded with some of the currently available metal-to-metal adhesives. The effects of this variable are sometimes neglected by testing laboratories. The results of an experimental evaluation of the mechanical behavior of a group on modern metal-to-metal adhesives as a function of the rate of load application are used to more accurately establish the importance of rate of load considerations in adhesive joint testing. An attempt is made to explain observations of other investigators engaged in adhesive joint ...


Steady State Temperature Distribution In A Rotating Disk, George Henry Morgan Jan 1959

Steady State Temperature Distribution In A Rotating Disk, George Henry Morgan

Masters Theses

"The purpose of this investigation was to obtain an expression for the steady state temperature distribution of a disk of uniform thickness rotating at a constant speed in ambient air while absorbing heat through the periphery at a constant rate. Engineers encounter such problems in connection with brakes of several varieties. The general solution obtained here could be extended to similar physical problems such as grinding wheels, disk clutches, and so on.

A differential equation was obtained for the temperature in the disk by the application of Fourier's conduction law and Newton’s convection law. A solution of this ...
