Abstract: ABSTRACT OF THE DISCLOSURE         A helicopter including a driven rotor assembly provided with a hub having oscillatable rotor blades extending outwardly therefrom and axially spaced portions of the hub having outer peripheral portions of a pair of annular flexible and elastic supporting diaphragms anchored relative thereto. Inner peripheral portions of the diaphragms are deflected and stretched toward each other and anchored to a supporting flange carried by a central rotary drive shaft of the rotor assembly.  A sleeve is longitudinally-shiftably mounted on the shaft below the rotor assembly and supports, through the utilization of a flexible and resilient diaphragm, a larger sleeve structure therefrom for universal angular displacement of the sleeve structure relative to the sleeve.  The sleeve structure includes control arms operatively con nected to the rotor blades for oscillation of the latter in response to axial shifting of the sleeve structure relative to the sleeve.  First control structure is provided for axially shifting the sleeve on the drive shaft and second control structure is provided for universally angularly displacing the sleeve structure relative to the sleeve.  The helicopter further includes a third diaphragm supported control structure whose diaphragm is flexed in opposition to the flexed diaphragm of the second control structure and is manually universally shiftable and operatively connected to the second control structure for similar universal displacement thereof.

Abstract: ABSTRACT OF THE DISCLOSURE A package is provided of wound strand of filaments coiled in layers, into a tubular configuration, with a sheet material covering of ionic polymer that has a surface attraction to the strand, for keeping the strand against the sheet material or film during unwinding of the strand from the package, completely through to the end of strand removal from the package.  Electrostatic charge is induced on the strand and sheet material, to create electrostatic attraction at their common interface, for holding the strand to the sheet material and preventing the last portion of a strand package that is being unwound, from becoming tangled.  Accordingly, this electrostatic attraction cuuses the film to support the outer strand coils in the package as the strand is withdrawn from the package, thereby preventing coils from slumping or falling together and becoming tangled.

Abstract: ABSTRACT OF THE DISCLOSURE    The present invention discloses a method and means for pulling a sucker rod string from the tubing of a well bore.  A separable connector is provided between thc sucker rod string and a downhole pump.  The separable connector is designed to separate when a predetermined tension load greater than the operating load upon the sucker rod string is applied to it.  If the downhole pump is already stuck upon its seat or becomes stuck within the tubing while being withdrawn, tension on the sucker rod string is increased until the separable connector separates, and the sucker rod string may be withdrawn, leaving the pump within the tubing.

Abstract: ABSTRACT OF THE DISCLOSURE          A radio communication system of the type where two or more transmit stations transmit a common signal using substantially identical frequency carrier waves is described.  Where the zones of the two stations overlap interference between the two waves occurs if the frequencies or phases of the two carriers are not the same.  The invention minimizes the effect of this interference by conveying the common signal directly from a signal generator to the first station but providing a delayed common signal to the second station.  Preferably the phase difference between the undelayed and the delayed signals is between 20° and 40° .  The substantially identical carrier waves which are generated in the two stations are modulated, in the case of the first station, by the undelayed common signal and, in the case of the second station, by the delayed common signal.  The type of modulation used is frequency or phase modulation.  It is provable mathematically and practically that the code error rate in the overlapping zone is reduced using this technique.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for applying stretchable plastic film to loads for containment of the loads using two frictionally connected rollers which are held together and driven by the film web at different speeds to elongate the plastic film beyond its yield point. After the elongated film has been stretched, it is wrapped around a rotating load.          The rollers are cammed apart during the beginning of the wrap so that relatively untensioned film is wrapped around the load at the beginning of the wrap.  The cam force is then released and the rollers are pulled together in frictional engagement by the film web being pulled off of the film roll to stretch the film web.
