Combustion of Liquid Fuels in Diesel Engine

Description: Hitherto, definite specifications have always been made for fuel oils and they have been classified as more or less good or non-utilizable. The present aim, however, is to build Diesel engines capable of using even the poorest liquid fuels and especially the waste products of the oil industry, without special chemical or physical preparation.

Underground Conditions in Oil Fields

Description: From Introduction: "This paper aims to show the general method of procedure in studying underground conditions in producing oil fields and how such study may not only correct but even prevent great unnecessary losses. Throughout the paper reference is made to oil wells and oil fields, but to a certain degree many of the suggestions relating to oil wells are applicable in the care and protection of gas wells and in solving gas problems."

A Résumé of the Advances in Theoretical Aeronautics Made by Max M. Munk

Description: "In order to apply profitably the mathematical methods of hydrodynamics to aeronautical problems, it is necessary to make simplifications in the physical conditions of the latter. In a valuable paper presented by Dr. Max M. Munk, of the National Advisory Committee for Aeronautics, Washington, to the Delft Conference in April, 1924, these necessary simplifying assumptions are discussed in detail. It is the purpose of the present paper to present in as simple a manner as possible some of the inte… more

The Stresses in Columns Under Combined Axial and Side Loads

Description: The problem before us is to determine the total stresses in an axially loaded column of any degree of restraint which is also subject to transverse bending both from a uniformly distributed load and from concentrated loads. The solution of this problem is of special importance in the design of aircraft which consist of slender columns" (p. 1).

Some Principles Governing the Establishment of Meteorological Stations Along Air Routes

Description: The organization of a meteorological service for an air route involves the solution of two distinct problems: distribution and grouping of meteorological stations and communications. Experience gained in the establishment of two lines, Paris-Warsaw and Constantinople-Bucharest enables us to establish certain principles, which may be of interest to note here.

Production and Briquetting of Carbonized Lignite

Description: From Introduction: "The Bureau of Mines since its establishment has always taken an active interest in the utilization of lignite and in the development of the lignite deposits of the United States. Extensive lignite fields occur in the west central States, notably in North Dakota, Montana, Wyoming, Colorado, and Texas; there are smaller areas in several other Sates, some of which are widely separated."

Stored-Grain Pests

Description: "Most of the damage done by insects to grain in storage and shipments is due to four species. These are the granary weevil, the rice or black weevil, the lesser grain borer or Australian weevil, and the Angoumois grain moth. Others of the 40 species or groups of species described in this bulletin can cause great damage to grain if storage conditions are unusually favorable for their increase.... These four pests live throughout their larval life entirely within the kernel, where they feed unsee… more
