Patent for turn signal improvements with an aim to improve visibility of signal and ease of replacement with the goal of communicating vehicular movement and reducing accidents.

Patent for improving cereal food processing by grinding corn and other grains into meal to convert starch into dextrin, and through drying grains to remove moisture and prevent fermentation (lines 17-23). Additionally, the processing will make the cereal appetizing and easily digestible.

Explains the fundamental principles of drying crude vegetable drugs. Provides drawings and instructions for constructing two types of driers.

Report presenting a discussion of the creation of a suitable aviation school and some of the characteristics that should be considered in terms of hiring personnel, creating a curriculum, and obtaining equipment.

Report presenting information regarding the usage of commercial and passenger service air routes and the fees and penalties involved in operating an air line.

This report contains a list of the courses relating to aeronautics announced in Germany, both in the technical high schools and in the universities.

A definition of "stalled fight" is presented as well as a detailed discussion on the how and why it occurs. Some suggestions are made to prevent its occurrence such as carrying an air speed instrument in the airplane.

The first part of this report details the efficiency and economy of airship travel, while the second part presents methods of economic efficiency with regards to construction, cost of upkeep and operation, and the establishment of airship lines.

The general idea was to record the air pressure on the spot, that is, without intervening tubes, by some simple automatic registering device. This was therefore made in such small dimensions that it could be inserted into the wing between the ribs and stand in direct connection with the pressure openings. The results of different experiments are presented along with the best locations for locating the instruments for recording the pressure.

This investigation was carried out by request of the United States Air Service in the wind tunnel of the Massachusetts Institute of Technology. The results are here published by the National Advisory Committee for Aeronautics as it is thought that they may be of general interest. Wings of the R.A.F. 6 section are tested with various angles of rake, and it is found that although rake has very little effect, a positive or negative rake of 30 degrees is the best.

Note presenting an investigation of various aspects of slotted wings, including some theoretical and experimental results and characteristics of certain slotted wings currently in production.

"The subject of the choice of an airfoil section is by no means a closed one, and despite the impossibility of making a single rule serve, it is quite practicable to deduce in a strictly rational manner a series of rules and formulas which are capable of being of the greatest use if we but confine ourselves to the consideration of one element of performance at a time. There are seven such elements of performance which are here taken up in turn. The seven are of different relative importance in different types of airplanes. The seven elements are: maximum speed regardless of minimum; maximum speed for given minimum; maximum speed range ratio; maximum rate of climb; maximum absolute ceiling; maximum distance non-stop; and maximum duration non-stop" (p. 1-2).

Patent for aeroplane construction to include improvements to air motor protection to minimize resistance and the use of air cups to direct the full force of air to the motor shaft, including illustrations.

Here, conceptions concerning vortices are illustrated by the simplest possible examples. Mathematical formulas and similar means of presentation, which, for the most part, do not help the understanding of persons not versed therein, have been avoided as much as possible. Instead, the author has endeavored to demonstrate the phenomena by means of simple geometrical and mechanical illustrations. For the sake of clarity, the author chiefly considers currents in one plane only, a situation that can be readily represented by diagrams. Some of the peculiarities of vortices in three dimensional flow are briefly discussed.

Patent for a new and improved condensed fertilizer formula that can be easily transported and is stable enough to be stored without appreciable deterioration, resulting in cost savings.

Patent for a burglar alarm, designed to be simply constructed and installed.

Patent for improving railway car frog replacement and holding. The improvements include greater strength and durability and low cost manufacture.

Patent for an apparatus to more easily and more economically remove well-casings from the ground when an oil well is no longer in use.

Patent for use by chiropractors in their manipulations of the human body, and has for its object the provision of a table or attachment to a table including simultaneously movable head and abdomen supports. The invention has been designed which embodies a head rest, chest support, and abdomen support all mounted upon a single hinged member which will automatically adjust itself to the patient laying upon the table, spring means being provided for opposing the movement.

Patent for a new and useful method of dealing the walls of deep wells in which the means for lining oil wells by the use of the customary metal casing is avoided, the cost is very materially reduced, and numerous expenses and failures are avoided.

Patent for an attachment for gun slings that can be used on army rifles or other guns and provides the means for the sling to be held tight against the arm for steady aim.

Patent for a cycle car that can be steered and propelled by hands only and can be used with ordinary bicycles.

Patent for a blow-out boot (as it pertains to tire repair). The defining feature of this invention is that the edges are flexible and overlapping, containing slots and loops that correspond to each other to facilitate the joining of the edges.

Patent for a coin wrapper (primarily used in banks) that uses a strip of carbon paper to create an imprint of the coins contained inside, which will remain after the coins are removed. The purpose of this is to create a record of the original number of coins to facilitate their counting and verification.
