Abstract: FIBERGLASS SUCKER ROD CONSTRUCTION        ABSTRACT OF THE DISCLOSURE         A fiberglass sucker rod construction is disclosed comprising a cylindrical fiberglass rod having a steel connector member adhesively bonded to each end thereof.  The steel connector members are basically identical in their manner of being affixed to each end of the fiberglass rod, each connector member having an internal receptacle defining a series of tapered annular spaces for receiving an epoxy adhesive material which bonds the fiberglass rod in the metal connector member, thereby forming a unitary sucker rod having a male thread connector at one end and a mating female connector at the other end thereof.  The epoxy adhesive cures, forming a sleeve having a series of annular tapering surfaces defining annular wedges that are oriented such that tension applied to the rod causes the wedges to be compressed between the rod and connector member, resulting in a radially inwardly directed force to retain the rod in position against such tension.

Abstract: PHM. 40 443               14 ABSTRACT:             A circuit is described for maintaining an input signal to a limiter used to limit amplitude excur-sions of a signal to be angle demodulated.  Means are pro-vided for detecting a temporary loss in signal to said limiter resulting from the loss of signal due to large negative amplitude modulation or other factors.  When the amplitude of the angle modulated wave falls below a pre-determined minimum, a substitute intermediate frequency signal is generated to maintain the limiter in a limiting condition during the temporary loss in broadcast signal. The substitute intermediate frequency signal has a fre-quency substantially equivalent to the intermediate fre-quency signal developed from the broadcast signal during periods when the amplitude of the broadcast signal is adequate.  The substitute signal prevents the occurrence of noise generated from an angle demodulator due to a temporary loss in signal.

Abstract: ABSTRACT      A method and apparatus for providing coincident orthogonally-polarized laser beams having twice the frequency of a fundamental frequency emitted by a laser source is dis-closed.  A second harmonic generator within a laser resonator cavity causes frequency-doubled laser beams to travel in opposite directions along an axis thereon.  One of the beams undergoes a polarization change of substantially 90° and is returned for travel along the laser axis in the same direction as a second frequency-doubled beam which has not undergone a polarization change.  The orthogonally-polarized beams are then emitted through an output mirror designed for transmitting beams of twice the frequency of the fundamental beam.
