Thanks Eric
I think I got it . . . ,
Make it Circuit-1 (old 555 circuit) and Circuit-2 (new 555 circuit)
Build circuit-2 similar to the one posted (circuit-1), omitting Q1, D1, RL1.
Adjust RV1, R3 and C1 for desired time needed in ms.
Connect J1(reset terminals) of Circuit-1 to (omitted RL1) of Circuit-2.
Use same trigger from the IR-beams to trigger both circuits same time,
Circuit-2 will keep the reset pin of Circuit-1 to ground for X-time ms,
See I do need a memory replacement does take time some times to snap into place.
Will try it this way.
Thanks

Thats good!, two heads are always better than one.
See how you go, come back if need be.
