Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 89 words
A Christmas tree lighting control including in combination a solid-state voltage supply source having a plurality of differing duty cycle outputs, a plurality of electrical outlets respectively connected to one or more of said duty cycle outputs for connecting thereto one or more strings of Christmas tree lights, driving means, a circuit control electrically interposed between said duty cycle outputs and said outlets and operative when driven by said driving means to to intermittently route, and in a predetermined order, voltage from said outputs to differing said electrical outlets.
Claim 2
Dependent Claim 89 words
A Christmas tree lighting control including in combination a solid-state voltage supply source having a plurality of differing duty cycle outputs, a plurality of electrical outlets respectively connected to one or more of said duty cycle outputs for connecting thereto one or more strings of Christmas tree lights, driving means, a circuit control electrically interposed between said duty cycle outputs and said outlets and operative when driven by said driving means to to intermittently route, and in a predetermined order, voltage from said outputs to differing said electrical outlets.
Claim 3
Dependent Claim 25 words
A Christmas tree lighting control as claimed in claim 1 wherein the duty cycle of each output of said voltage supply may be selectively varied.
Claim 4
Dependent Claim 27 words
A Christmas tree lighting control as claimed in claim 1 wherein the duty cycle of at least two oF said voltage source outputs may be selectively varied.
Claim 5
Dependent Claim 78 words
A Christmas tree lighting control as claimed in claim 1 including a plurality of contact segments one or more of which are connected respectively to each of the output of said voltage supply, insulating means respectively separating said contact segments, contact means respectively connected to said electrical outlets and operative as the control is driven by said driving means to span the insulation separating said contact segments to respectively engage simultaneously at least two of said contact segments.
Claim 6
Dependent Claim 142 words
A Christmas tree lighting control including in combination a solid-state voltage supply having a plurality of differing duty cycle outputs, a plurality of electrical outlets continuously in circuit with said outputs for connecting thereto one or more strings of Christmas tree lights, driving means, a circuit control interposed between said outputs and said electrical outlets and operative when driven by said driving means to intermittently route, and in a predetermined order, voltage from said outputs to differing said electrical outlets, said control including a plurality of contact segments, means electrically connecting said contact segments with said voltage outputs, contact means respectively connected to said electrical outlets and electrically engaging one or more of said contact segments, said contact being operative upon relative movement between said contact means and said contact segments to pass voltage from said contact segments to said electrical outlets.
Claim 7
Dependent Claim 142 words
A Christmas tree lighting control including in combination a solid-state voltage supply having a plurality of differing duty cycle outputs, a plurality of electrical outlets continuously in circuit with said outputs for connecting thereto one or more strings of Christmas tree lights, driving means, a circuit control interposed between said outputs and said electrical outlets and operative when driven by said driving means to intermittently route, and in a predetermined order, voltage from said outputs to differing said electrical outlets, said control including a plurality of contact segments, means electrically connecting said contact segments with said voltage outputs, contact means respectively connected to said electrical outlets and electrically engaging one or more of said contact segments, said contact being operative upon relative movement between said contact means and said contact segments to pass voltage from said contact segments to said electrical outlets.
Claim 8
Dependent Claim 151 words
A Christmas tree lighting control including in combination a solid-state voltage supply source having a plurality of differing duty cycle outputs, a plurality of electrical outlets continuously in circuit with said voltage supply outputs for electrically connecting thereto one or more strings of Christmas tree lights, driving means, a circuit control interposed between said voltage supply and said electrical outlets and operative when driven by said driving means to intermittently route and in predetermined order voltage from said differing duty cycle outputs to differing said electrical outlets, said control including a plurality of contact segments electrically connected to said voltage supply source, pairs of contact members electrically engaging one or more of said contact segments and connected as pairs respectively to said electrical outlets for passing voltage from said contact segments to said outlets when relative movement between said contact segments and said contact pairs is effected by said driving means.
Claim 9
Dependent Claim 151 words
A Christmas tree lighting control including in combination a solid-state voltage supply source having a plurality of differing duty cycle outputs, a plurality of electrical outlets continuously in circuit with said voltage supply outputs for electrically connecting thereto one or more strings of Christmas tree lights, driving means, a circuit control interposed between said voltage supply and said electrical outlets and operative when driven by said driving means to intermittently route and in predetermined order voltage from said differing duty cycle outputs to differing said electrical outlets, said control including a plurality of contact segments electrically connected to said voltage supply source, pairs of contact members electrically engaging one or more of said contact segments and connected as pairs respectively to said electrical outlets for passing voltage from said contact segments to said outlets when relative movement between said contact segments and said contact pairs is effected by said driving means.
