Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 64 words
A process for producing a rapidly-soluble, structurally-strong, storage-stable tablet of sodium dichloroisocyanurate dihydrate which comprises placing a particulate material consisting essentially of sodium dichloroisocyanurate dihydrate into a structure forming apparatus, compressing the sodium dichloroisocyanurate dihydrate with a compression pressure of about 2,000 to about 10,000 p.s.i., and recovering a rapidly-soluble, structurally-strong, storage-stable tablet which is resistant to deterioration and dimensional change due to moisture.
Claim 2
Dependent Claim 64 words
A process for producing a rapidly-soluble, structurally-strong, storage-stable tablet of sodium dichloroisocyanurate dihydrate which comprises placing a particulate material consisting essentially of sodium dichloroisocyanurate dihydrate into a structure forming apparatus, compressing the sodium dichloroisocyanurate dihydrate with a compression pressure of about 2,000 to about 10,000 p.s.i., and recovering a rapidly-soluble, structurally-strong, storage-stable tablet which is resistant to deterioration and dimensional change due to moisture.
Claim 3
Dependent Claim 18 words
The process of claim 1 wherein a pressure of 5,000 p.s.i. is used to compress the sodium dichloroisocyanurate.
