Abstract: ABSTRACT        An apparatus for bracing items of freight on the loading platform of a freight carrying vehicle has a rod or cable tie-down having one end connected to an anchor on the loading platform. The opposite end of the tie-down is positioned through an aperture in a frame member of the item of freight. First and second locking means are positioned over the opposite end of the tie-down with an expansion means therebetween. The locking means slide over the cable in one direction but lock to the cable in the opposite direction.          When the expansion means expands, one locking means grabs the cable While the other is slid along the cable into tight abutment with the frame member to create a tension in the cable.

Abstract: ABSTRACT OF THE DISCLOSURE           The inventive system requires that normal approach indicated airspeed and a predetermined approach groundspeed be used as the approach criteria, whichever is the least, compared to its own predetermined index value.  These two values are the commanding functions fed to a fast/slow indicator and to any auto-throttle device on the approach, along with a "caution tailwind" warning device to warn the pilot whenever the groundspeed exceeds true airspeed by 5 knots or more, for example.  If this warning activates, he should consider cancelling the approach and choose an approach from a different direction, determined by surface wind and his drift at the time of cancellation.  This condition is caused by a tailwind component at altitude, the value of which the pilot can determine from his airspeed and groundspeed indications.

Abstract: BEHIND CASING WATER FLOW DETECTION USING PULSED NEUTRON OXYGEN ACTIVATION             (D#74,199-2F) ABSTRACT OF THE DISCLOSURE        Measurement of the linear flow velocity and volume flow rate of undesired behind casing water flow is provided.  A well tool having a 14 MEV pulsed neutron source is used to irradiate the earth formations behind well casing with bursts of high energy neutrons.  This irradiation activates elemental oxygen nuclei comprising the molecular structure of the undesired flow.  Dual spaced gamma ray detectors located above or below the neutron source detect the decay of unstable isotope nitrogen 16 produced by the oxygen activation in the time intervals between the neutron bursts.  Background radiation due to prompt N-7 radiation is thus largely avoided.  From the detected nitrogen 16 characteristic gamma rays the linear flow velocity of the undesired flow is determined.  By combining this with an estimation of the distance R to the undesired flow region from the detectors, the volume flow rate V may be deduced.                             I

Abstract: ABSTRACT OF THE DISCLOSURE     Opposed pivotally mounted tamper arms are oscillated by respective single-acting hydraulic piston assemblies controlled by separate hydraulic duplex rotary distributing valves.  Fluid supply and return lines for each piston assembly are connected to a source of pressurized hydraulic fluid via the respective rotary valve.  Each valve has a stationary ported shell which receives a rotary cylindrical spool having a pair of axially displaced supply and return throughports which alternately register with supply and return line ports in the shell to open and close the connec-tions between the respective piston assembly and the supply and return lines.  While the rotary valves are preferably driven by a common drive unit, the relative phase of the oscillations of the arms can be determined by rotationally offsetting one of the spools with respect to the other by the desired phase angle.
