Dr Cash $1,225,000
Dr Accumulated depreciation $200000
Cr Patent asset account $170000

Explanation:
The entries have been passed based on the sales of patent and equipment where the sum of $1225000 was realized in cash($850000+$375000).
The gain on the disposal of $595000, is arrived at by deducting book values of the asset from the proceeds on disposal($1225000-$170000-$460000).
The entry passed in accumulated depreciation is to write off the accumulated depreciation on the equipment sold.
