Title: Impulse autocorrelation function communications system
Inventor: GUTLEBER FRANK S
IPC: H04B7/10

Granted: 1986-02-18
Abstract: Abstract of the Disclosure A pulse code modulation communications system employing orthogonally separated noise code mate pairs having autocorrelation functions which upon detection in a matched filter and addition compress to a lobeless impulse.  A mate pair of bi-polar digital noise codes are impressed on respec-tive RF carriers generated by the same frequency source with one code mate being transmitted separately as a vertically polarized wave while the other code mate is transmitted separately as a horizontally polarized wave.  The polarized RF carrier signals containing the code mates are respectively received by hori-zontally and vertically polarized antennas coupled to radio receiver apparatus which provides respective received signals containing the code mates.  The code mates are then detected by matched filters which operate to compress the code mates.          The compressed code mates are then linearly added to provide an output signal comprising a lobeless impulse signal.

Abstract: 51,191 ABSTRACT OF THE DISCLOSURE         A three phase core form transformer for use in a three phase dual dynamic stabilizer system that provides reactive power compensation.  The transformer has a three legged  magnetic  core,  a plurality of primary windings corresponding  to  the  phases,  two  auxiliary  secondary windings per phase that are wound to provide first and second common bifilar portions, and a plurality of prin-cipal secondary windings corresponding to the number of primary windings.  The first common bifilar portion,  the principal  secondary winding,  the  second  common bifilar portion and the primary winding are placed coaxially and radially adjacent,  in  the recited order,  starting from each leg of the magnetic core.          The primary windings  are  connected  in  delta. The principal secondary windings and auxiliary secondary windings are connected in a forked wye wherein one auxili-ary secondary winding of each of the other two phases is electrically connected to the free end of each of the wye connected principal  secondary windings.  This results in all three phases  being present  in each combination  of principal  secondary  windings  and  auxiliary  secondary windings.  With this arrangement of windings the leakage reactance  of  the  principal  secondary  winding  and  the common leakage reactance of the auxiliary secondary wind-ings attached thereto for each phase are positive in value with the  leakage  reactance  of  the  principal  secondary winding being made to be about twice that of the common leakage reactance of the auxiliary windings.   51,191 The primary windings can be  continuous  wound windings with the principal  secondary windings and the auxiliary secondary windings being helitran wound windings.
