Document issued by the Office of the Attorney General of Texas in Austin, Texas, providing an interpretation of Texas law. It provides the opinion of the Texas Attorney General, Will Wilson, regarding a legal question submitted for clarification: Whether or not the Civil Defense and Disaster Relief, Vocational Schools, Civil Air Patrol and Texas Turnpike Authority are exempt from the registration fees of vehicles owned and used by them.

This report details a meeting held for the purpose of acquainting all interested parties with the present problems being encountered in the canning process. A short discussion of previous canning methods and their problems was presented as background information. The search for a bonding agent to bond the aluminum can to the uranium core covered such materials as AlSi, lead, tin, aluminum, and copper. Mach of this early work was guided by the University of Chicago. The Grasselli (du Pont) Laboratory developed the triple-dip process where the uranium was first heated in a copper-tin bath, rinsed in a tin bath, then canned in an AlSi bath with AlSi as the bonding agent. It appeared at this time that the best AlSi composition to use was a little toward the aluminum side of the eutectic composition of 12.5 percent silicon. A current problem and the one with which this meeting was primarily concerned is that of bond failure where the bond between the can and core is broken. Variables found in this most recent study to have an effect on the strength or quality of the bonding layer are discussed.

Report presenting an investigation to determine the aerodynamic characteristics in pitch at a Mach number of 6.8 of hypersonic missile configurations with cruciform trailing-edge flaps and all-movable control surfaces. Testing indicated that all-movable controls on the flared-afterbody model should be capable of producing much larger values of trim lift and of normal acceleration than the trailing-edge-flap configuration. Some of the configurations tested include body alone, body with 5 degree fins and trailing-edge flaps, and body with 10 degree flare and all-movable controls.

"The static aeroelastic divergence characteristics of a delta-plan-form model of the canard control surface of a proposed air-to-ground missile have been studied both analytically and experimentally in the Mach number range from 0.6 to 3.0. The experiments indicated that divergence occurred at a nearly constant value of dynamic pressure at Mach numbers up to 1.2. At higher Mach numbers somewhat higher values of dynamic pressure were required to produce divergence" (p. 1).

Particle detection instruments may be divided into two classes; devices which see the actual path of the particle, and counting devices which indicate the passage of a particle. Examples of each class are given, the characteristics of each example are tabulated, and the uses for each device are discussed. (D.E.B.)

Report discussing an investigation to determine the aerodynamic characteristics of hypersonic missile configurations with cruciform trailing-edge flaps with all-movable control surfaces. The all-movable controls were found to produce much larger values of trim lift and normal acceleration than the trailing-edge-flap configuration.

Report presenting a flight investigation to determine the low-speed flight characteristics of a 45 degree swept-wing fighter-type airplane with boundary-layer control on the trailing-edge flaps. The effectiveness of the flap with and without boundary-layer control was determined in conjunction with several slat modifications. The study also included low-speed flying qualities and a pilot evaluation of the operational use of the boundary-layer control system in landing approaches.

From Introduction: "The results obtained in the wind-tunnel tests at Mach numbers 2.36 and 2.87 for several configurations utilizing this wing, including results on the wing alone are presented."
