Narrative:

Light transport came to me from bay approach climbing to 15000'. I had traffic at 14000' northbound so I stopped light transport at 13000' and coordinated with bay approach. Light transport came within 3 mi of medium large transport same altitude. Although sector 12 has control of data block, I (35) happened to be talking to him. I climbed light transport to FL250 and gave him 250 degree heading. I turned medium large transport to 180 degree heading. He said that he was already on 180 degree heading. I turned him to 160 degree heading and switched him to sector 12 frequency when light transport was out of 14000'.

Title: RADAR SEPARATION WAS LOST BETWEEN 2 DEPARTING ACFT.

Narrative: LTT CAME TO ME FROM BAY APCH CLBING TO 15000'. I HAD TFC AT 14000' NBND SO I STOPPED LTT AT 13000' AND COORDINATED WITH BAY APCH. LTT CAME WITHIN 3 MI OF MLG SAME ALT. ALTHOUGH SECTOR 12 HAS CTL OF DATA BLOCK, I (35) HAPPENED TO BE TALKING TO HIM. I CLBED LTT TO FL250 AND GAVE HIM 250 DEG HDG. I TURNED MLG TO 180 DEG HDG. HE SAID THAT HE WAS ALREADY ON 180 DEG HDG. I TURNED HIM TO 160 DEG HDG AND SWITCHED HIM TO SECTOR 12 FREQ WHEN LTT WAS OUT OF 14000'.
