Surface Impregnation Of Wood : Ii. Gaseous Impregnation Of Wood : Iii. Investigations On Submarine Decking : Iv. Investigation Of Marine Adhesives., Otto J. Mileti
Electronic Theses and Dissertations
This thesis presents results on methods used to produce a hard surfaced wood product. The methods involve the parting of the wood fibers on the surface by a special serrating tool, followed by surface impregnation and final curing. The serrations on the wood surface produce an artificial grain upon curing. A preliminary investigation was made to improve the rot-resistance of wood by gaseous treatment. Results of such treatments show some limited success with formaldehyde on yellow poplar and warrant further study. An investigation was made to find a substitute for teak wood used on submarine decking. A number of combinations …
Heat Transfer To Fuel Oil In Viscous Flow-Characteristics Of A Fin-Type Heat Exchanger., Boyd R. Abbott Jr.
Heat Transfer To Fuel Oil In Viscous Flow-Characteristics Of A Fin-Type Heat Exchanger., Boyd R. Abbott Jr.
Electronic Theses and Dissertations
A unit was constructed for the study of film heat transfer coefficients of a heavy fuel oil in viscous or streamline flow. The heat exchanger was of the shell and tube type, having extended longitudinal steel fins welded to the tube. Auxiliary equipment consisted of an oil pump, oil storage reservoirs, piping, and means for measurement of temperatures and oil flow rates. The unit was operated both as a fin type heat exchanger with the oil in contact with the finned surfaces, and as a straight tube and shell exchanger with the oil on the tube side. Oil flow rates …
The Reaction Of Ethylcellulose With Fatty Acid And Its Application To The Varnish Industry : Ii. Ethylcellulose In Pencil Lacquers., Albert L. Kimmel
The Reaction Of Ethylcellulose With Fatty Acid And Its Application To The Varnish Industry : Ii. Ethylcellulose In Pencil Lacquers., Albert L. Kimmel
Electronic Theses and Dissertations
Ethylcellulose was refluxed with Stearic, Oleic, Linseed Fatty acids, and a neutral Mineral Oil in the presence of a solvent. The products recovered were analyzed to determine if any possible reaction had taken place. Conditions for the reaction were carried out so that the temperatures obtained could be in the near range of varnish cooking, that is between 375 and 500°C. The I solvents used were diethylbenzene, boiling point 180oC and tetralin, boiling point 208oC. In each case approximate stoichiometric proportions of the fatty acids and ethylcellulose were used. These were refluxed to a sensible minimum viscosity of solution. The …
