Test 264: Farmall F-20, Nebraska Tractor Test Laboratory Collected By Larsen Museum Jan 1936

Test 264: Farmall F-20, Nebraska Tractor Test Laboratory Collected By Larsen Museum

Nebraska Tractor Tests

EXPLANATION OF TEST REPORT: Farmall F-20

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.

Stresses In Moderately Thick Rectangular Plates , Archie Higdon Jan 1936

Stresses In Moderately Thick Rectangular Plates , Archie Higdon

Retrospective Theses and Dissertations

By the use of recurrence relations the displacements, which satisfy the equilibrium equations, are expressed in terms if U0, V0, U1, V1, W0 and W1;The partial differential equations defining these six functions are obtained for any normal load which can be represented as a polynomial in x,y continuous over the entire plate;These equations are solved for the particular load P1+axa+ byb subject to three different sets of edge conditions: pinned-pinned, pinned-free, pinned-clamped;The results show that the principal part of the vertical displacement of the middle surface is W00, the corresponding thin plate solution. With the ...

Efficiencies Of Petroleum Distillates As Cooling Media For Internal Combustion Engines , Richard Seymour Apple Jan 1936

Efficiencies Of Petroleum Distillates As Cooling Media For Internal Combustion Engines , Richard Seymour Apple

Retrospective Theses and Dissertations

When kerosene or other petroleum distillates are used as cooling media for internal combustion engines, the danger from freezing, fire or corrosion is nil;When used with a quality grade of radiator hose, only slight deterioration takes place, and hoses have shown satisfactory condition after one year's use;The increase in the operating temperature of the motor is only slight and should produce an advantage during the cold weather.

Means For Cooling Combustion Chambers, Robert Goddard Oct 1935

Means For Cooling Combustion Chambers, Robert Goddard

WPI Innovations

This invention relates to means and a method for cooling the walls of combustion chambers or of other highly heated cylinders or containers. The invention is designed to replace or supplement the usual means of cooling by water jackets or by other cooling applications externally of the cylinder, as such external applications have been found impractical under very high temperature conditions and particularly when used in continuous combustion apparatus. It is the object of my invention to provide means for cooling a combustion chamber or similar container by injecting a cooling fluid directly into the container and adjacent a wall ...

Heat-Absorbing Apparatus For Use With Solar Energy, Robert Goddard

WPI Innovations

This invention relates to means for absorbing solar energy and heating a fluid by the absorbed energy. One object of my invention is to provide apparatus by which a fluid thus heated may be discharged from the apparatus at a definite and predetermined temperature. Other objects of the invention are the provision of means for increasing the rate of circulation of a heat-conducting liquid in the apparatus, and means for automatically preventing the cooling of the apparatus by the passage of clouds over the face of the sun.
