Narrative:
Widebody transport was direct hoxie intersection at FL370. Air carrier X was on a 035 degree heading at FL370. I next received handoffs on air carrier Y and XXXX from hudson at FL370. With the last 2 handoffs I decided the heading on air carrier X was no good. I received control to climb widebody transport to FL390 and did so. I cleared air carrier X to jhw VOR, but the LORAN controller hadn't turned him over. I finally talked to air carrier X and cleared him to jhw VOR. I was then relieved from position. I briefed him and explained the traffic situation. He said he had the position. I asked if he wanted me to stay until the situation was resolved. He then unplugged me. I stayed behind the radar controller to watch until the situation was resolved. We both thought widebody transport and air carrier X still weren't looking good, so the radar controller issued a 30 degree left turn to air carrier X. I said air carrier X was in a right turn and maybe a right turn would be better. The controller issued another 30 degree left turn. At that time, it sounded like the pilot was not responding promptly. When air carrier X and widebody transport were clear, air carrier X was cleared to alb VORTAC, then turned to a heading of 100 degrees because of air carrier Y. Air carrier X again seemed not to be responding promptly (I was not plugged in). Air carrier Y was issued a 30 degree left turn and descent to FL350. Air carrier Y and air carrier X minimum sep was 4.5 mi 900'. The left turns issued air carrier X to miss widebody transport put him in conflict with air carrier Y. A right for air carrier Y and left turn for widebody transport might have resolved the whole thing.

Title: LOSS OF SEPARATION OCCURRED BETWEEN ACR X AND ACR Y WHILE ON RADAR VECTORS.
Narrative: WDB WAS DIRECT HOXIE INTXN AT FL370. ACR X WAS ON A 035 DEG HDG AT FL370. I NEXT RECEIVED HDOFS ON ACR Y AND XXXX FROM HUDSON AT FL370. WITH THE LAST 2 HDOFS I DECIDED THE HDG ON ACR X WAS NO GOOD. I RECEIVED CTL TO CLB WDB TO FL390 AND DID SO. I CLRED ACR X TO JHW VOR, BUT THE LORAN CTLR HADN'T TURNED HIM OVER. I FINALLY TALKED TO ACR X AND CLRED HIM TO JHW VOR. I WAS THEN RELIEVED FROM POS. I BRIEFED HIM AND EXPLAINED THE TFC SITUATION. HE SAID HE HAD THE POS. I ASKED IF HE WANTED ME TO STAY UNTIL THE SITUATION WAS RESOLVED. HE THEN UNPLUGGED ME. I STAYED BEHIND THE RADAR CTLR TO WATCH UNTIL THE SITUATION WAS RESOLVED. WE BOTH THOUGHT WDB AND ACR X STILL WEREN'T LOOKING GOOD, SO THE RADAR CTLR ISSUED A 30 DEG LEFT TURN TO ACR X. I SAID ACR X WAS IN A RIGHT TURN AND MAYBE A RIGHT TURN WOULD BE BETTER. THE CTLR ISSUED ANOTHER 30 DEG LEFT TURN. AT THAT TIME, IT SOUNDED LIKE THE PLT WAS NOT RESPONDING PROMPTLY. WHEN ACR X AND WDB WERE CLR, ACR X WAS CLRED TO ALB VORTAC, THEN TURNED TO A HDG OF 100 DEGS BECAUSE OF ACR Y. ACR X AGAIN SEEMED NOT TO BE RESPONDING PROMPTLY (I WAS NOT PLUGGED IN). ACR Y WAS ISSUED A 30 DEG LEFT TURN AND DSCNT TO FL350. ACR Y AND ACR X MINIMUM SEP WAS 4.5 MI 900'. THE LEFT TURNS ISSUED ACR X TO MISS WDB PUT HIM IN CONFLICT WITH ACR Y. A RIGHT FOR ACR Y AND LEFT TURN FOR WDB MIGHT HAVE RESOLVED THE WHOLE THING.
