Report discussing a new instrument is described which is capable of simultaneously recording the position of the three controls of an airplane. The records are taken photographically on a standard N.A.C.A. film drum and the instrument can be quickly installed in any airplane.

The aerial convention delegates are listed as well as the set of rules that were developed during the session.

This report presents a recounting of the steps taken by France to establish national and international regulation over air traffic.

This article considers some of the causes which hinder the development of aircraft insurance. Different risks are discussed as well as the causes of aircraft accidents. Pilot error, poor airdromes, weather conditions, poorly adapted airplanes, and engine failures are all examined and some conclusions are made.

Monthly literary journal of A. & M. College of Texas containing original short stories, essays, poetry, and other creative works written by students.

Describes the characteristics of the boll weevil, the damage that it causes to crops, and methods for its control.

Patent for a brake (as it pertains to vehicles), that is operated by hand and that employs the use of brake bands and a drum to alter the momentum of a vehicle.

The author lists rules for the development and planning of air routes. He uses as examples India and Texas, as well as discussing the need for more landing fields.

Patent for a foldable steering wheel with the capability of swinging downwardly to an out of the way position to enable the driver to easily occupy or leave his seat.

Patent for hair clippers that simplifies construction, reduces vibration, and improves efficiency.

Patent for improving structure of clipper forming co-pending application Serial No. 469,842. Simplifying manufacturing and adding other features.

Patent for improvements to hoisting drums for use in drilling oil, gas, and water wells, with the object being "to employ a plurality of hoisting drums upon the same shaft so that the cable may be wound partly on one drum and partly on another" (lines 73-76) such that the danger of cable cutting is decreased and the speed of operation is increased, including illustrations.

Patent for a device to reliably and effectively secure the radiator cap in position on the filling neck of a radiator in order to avoid displacement. Device is of simple and durable construction and inexpensive to manufacture.

Patent for a lubricating oil dispenser designed specifically to dispense lubricants and similar liquids. Dispenser is formed with a transparent container tubes to show the customer the character of the liquid being dispensed.

Patent for improvements to the measuring device used to ascertain the depth of a well.

This report examines the great utility and safety of using instruments when flying. Instruments can be especially useful in conditions when the pilot has trouble spatially orienting himself.

Dr. Warner examines the utility and economy of flying at night when flying passengers. Some of the points discussed include lighted landing fields, the possibility of using airships, and the cost of landing fields.

The choice of the numbers of revolutions and of the diameter, the distribution of thrust, and the values of the constants in the aerodynamical equations of the propeller are discussed.

The air flow and the air force created by all elements of the propeller blades lying in a ring located between two concentric circles around the propeller axis are independent of what happens in other rings.

"No rational column formula has yet been developed which gives results which are sufficiently precise for the design of airplane members, and consequently it is necessary to fall back upon experimental testing. In order to derive the maximum benefit from experiments, however, it is necessary that the experiments be guided by theory. It is the object here to modify existing formulae that may be obtained with a minimum number of tests" (p. 1).

Patent for a burner that can use both oil and gas as fuel.

Patent for a power transmission with improvements to mechanisms related to frame adjustment, lubrication, motion transmission, and speed gearing, among others.

Patent for a method for drawing a higher quality and grade of oil from a well through the combination with gas trapped in the well.

This report presents a brief history of France's attempts to promulgate an internal air traffic law and then provides a draft of proposed national air traffic laws.
