59, for holdover solid coolant accumulating processes which hold-over is intended for use without removal.

60, for processes involving packaging.

62, for processes of cooling an article which is initially an identifiable fixed entity.

80+, for defrosting processes.

151+, for automatic control apparatus. 272+, for condensate handling.

340+, for shaped or modified congealed product producing apparatus.

532+, for fractionally solidifying and separating processes.

601+, for solidified gas producing processes and apparatus there provided for.
