Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
85 words
An ultraviolet light processor comprising: a. a sequence of members for emitting ultraviolet light when connected to a source of electrical power; b. means for automatically and sequentially connecting members of said sequence to a source of electrical power to thereby cause said members to emit ultraviolet light; and c. timing means including only a single timing relay, said timing means cooperating with said connecting means for interposing a time interval between connections of adjacent members of said sequence to said source of electrical power.
Claim 2
Dependent Claim
85 words
An ultraviolet light processor comprising: a. a sequence of members for emitting ultraviolet light when connected to a source of electrical power; b. means for automatically and sequentially connecting members of said sequence to a source of electrical power to thereby cause said members to emit ultraviolet light; and c. timing means including only a single timing relay, said timing means cooperating with said connecting means for interposing a time interval between connections of adjacent members of said sequence to said source of electrical power.
Claim 3
Dependent Claim
21 words
The ultraviolet light processor of claim 1 including means for initiating the operation of said connecting means and said timing means.
