Issues Involved:
1. Entitlement to exemption under Notification No. 7/65-C.E.
2. Validity of show cause notice period.
3. Applicability of Trade Notice No. 220/81 and Tariff Advice No. 83/81.

Issue-wise Detailed Analysis:

1. Entitlement to exemption under Notification No. 7/65-C.E.:
The appellant, a small-scale industry manufacturing liquid Carbon Dioxide (CO2), was initially granted an L 6 license under Notification No. 7/65, which exempted carbon dioxide used for any "industrial purpose" from excise duty. The Assistant Collector later revoked this benefit, asserting that the appellant did not use the CO2 for any industrial purpose other than self-sale. The Appellate Collector of Central Excise overturned this decision, referencing Trade Notice No. 220/81, which indicated that impure CO2 not meeting ISI specifications should be classified under Item 68, not 14H, thus qualifying for the exemption. However, the Appellate Tribunal reversed this, arguing that the Trade Notice was issued three years after the relevant period.

2. Validity of show cause notice period:
The show cause notice dated 20-11-1978 covered the period from March 1977 to September 1978, but the duty demand extended up to February 1982. The Supreme Court found this to be a violation of natural justice, as the appellant was not given proper notice for the extended period. This discrepancy rendered the proceedings unfair and vitiated the demand for the extended period.

3. Applicability of Trade Notice No. 220/81 and Tariff Advice No. 83/81:
The Appellate Collector relied on Trade Notice No. 220/81, which stated that CO2 not conforming to ISI specifications should be classified under Item 68, making it eligible for the exemption. The Appellate Tribunal dismissed this, citing a later Tariff Advice No. 6/85, which purportedly classified such CO2 under Item 14H. The Supreme Court criticized the Tribunal for basing its decision on assumptions and not adequately considering the earlier Trade Notice and Tariff Advice. The Court emphasized that the earlier advice was binding and had not been rescinded, thus the appellant should benefit from the doubt.

Conclusion:
The Supreme Court set aside the Appellate Tribunal's order, reinstating the Appellate Collector's decision that granted the exemption to the appellant. The Court underscored the importance of adhering to procedural fairness and the binding nature of the earlier Trade Notice and Tariff Advice. The appeal was allowed, restoring the order of the Appellate Collector dated 18-6-1982, with no order as to costs.
