The 8 pin package you have with sn72741p is an Operational Amplifier (OpAmp) made by Texas Instruments. The Ancom 741, I believe might be a custom chip that was made by (or for) Ancom Electronics, which was an electronic equipment manufacturer based out of California in the '70s

Assuming the packages are still functional, AND that the pinouts match the common 741 series OpAmps, they could be used in any circuit which requires a 741 OpAmp.

The OpAmp is useful in circuits which call for a "741" OpAmp, as it is one of the same family. The Ancom chip is more difficult to say without being able to find any specifics on the chip. I would suggest building a simple circuit that calls for an LM741 opamp on a breadboard (Google helps here), take note of the output of the circuit so you ave a reference, then swap the chips one at a time and note the output of the circuits with those. If your outputs are nearly the same, then you could use the chips in such a circuit. That Ancom chip might also be a 741 class OpAmp as well.
