Test 240: Caterpiller Model 50 (Diesel), Tractor Museum

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 ...

Apparatus For Absorbing Solar Energy, Robert Goddard Aug 1934

Apparatus For Absorbing Solar Energy, Robert Goddard

WPI Innovations

This invention relates to apparatus by which solar energy may be effectively utilized in the heating of water, the production of steam of the raising of any fluid to a higher temperature. It is the general object of my invention to provide apparatus for such purposes so designed that a relatively large heating action may be attained by use of a relatively small apparatus. A further object of my invention is to provide apparatus which is simple in construction, reliable and efficient in operation and which involves the use of no moving parts. My improved apparatus produces rapid and complete ...


Method Of Welding Thin Metal Structures, Robert Goddard Aug 1934

Method Of Welding Thin Metal Structures, Robert Goddard

WPI Innovations

This invention relates to the fabrication of metal structures from sheets or other sections of relatively thin metal by welding together the edges of such sheets or sections. While capable of somewhat general application, the invention relates particularly to the production of structures from relatively thin heat-treated metal, more commonly in the form of sheets or plates. Light weight tanks and cylinder are types of such structures.


Focusing Mirror And Directing Mechanism Therefor, Robert Goddard Mar 1934

Focusing Mirror And Directing Mechanism Therefor, Robert Goddard

WPI Innovations

This invention relates to a focusing mirror adapted for use in solar heating apparatus, and to mechanism for directing the mirror toward the sun. It is one object of my invention to provide an improved mirror for such purposes so designed that a mirror of large size may be easily and economically constructed and that the curvature and focal length of the mirror may be readily adjusted to suit operating conditions. Another object of my invention is to provide improved mechanism for directing the mirror toward the sun and for automatically maintain the mirror in such adjustment. To the accomplishment ...


Heat-Absorbing Apparatus For Use With Solar Energy, Robert Goddard Mar 1934

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.

A Study Of Five Commercial Electric Stoves, A. E. Baragar, Edna B. Snyder Oct 1933

A Study Of Five Commercial Electric Stoves, A. E. Baragar, Edna B. Snyder

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Five commercial electric stoves having major variations in types of surface units, in the construction, lining, and insulation of the oven, and in the retail price were studied to determine (1) the efficiency and time of heating of the various surface units, and (2) the merits of differently constructed ovens.
