Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
57 words
An electrically heated blanket comprising two layers of textile fabric interconnected throughout major portions thereof along a series of spaced parallel lines by discontinuous adhesive material to form a series of dividers with adjacent dividers defining parallel channels therebetween, with opposite ends of the channels being unobstructed and open-ended, and electric heating wire positioned in said channels.
Claim 2
Dependent Claim
57 words
An electrically heated blanket comprising two layers of textile fabric interconnected throughout major portions thereof along a series of spaced parallel lines by discontinuous adhesive material to form a series of dividers with adjacent dividers defining parallel channels therebetween, with opposite ends of the channels being unobstructed and open-ended, and electric heating wire positioned in said channels.
Claim 3
Dependent Claim
62 words
An electrically heated blanket comprising two layers of textile fabric interconnected throughout major portions thereof along a series of spaced parallel lines by rows of small discrete dots of adhesive material to form a series of dividers with adjacent dividers defining parallel channels therebetween, with opposite ends of the channels being unobstructed and open-ended, and electric heating wire positioned in said channels.
Claim 4
Dependent Claim
62 words
