Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
59 words
A hydraulic brake hose comprising an elastomeric core tube, a reinforcing braid of twisted glass fiber yarn wound around said tube braided at an angle of about 52° to 56° to the axis of the tube, an elastomeric cushion layer covering said glass braid, reinforcing braid of untwisted nylon fibers over said cushion layer, and an elastomeric cover layer.
Claim 2
Dependent Claim
59 words
A hydraulic brake hose comprising an elastomeric core tube, a reinforcing braid of twisted glass fiber yarn wound around said tube braided at an angle of about 52° to 56° to the axis of the tube, an elastomeric cushion layer covering said glass braid, reinforcing braid of untwisted nylon fibers over said cushion layer, and an elastomeric cover layer.
Claim 3
Dependent Claim
67 words
A hydraulic brake hose comprising an elastomeric core tube, a reinforcing braid of glass fibers twisted at a rate of one-half to five twists per inch and braided at an angle of about 52° to 56° to the axis of the tube, an elastomeric cushion layer covering said glass braid, a reinforcing braid of untwisted, nonheat-set nylon fibers over said cushion layer, and an elastomeric cover layer.
Claim 4
Dependent Claim
67 words
A hydraulic brake hose comprising an elastomeric core tube, a reinforcing braid of glass fibers twisted at a rate of one-half to five twists per inch and braided at an angle of about 52° to 56° to the axis of the tube, an elastomeric cushion layer covering said glass braid, a reinforcing braid of untwisted, nonheat-set nylon fibers over said cushion layer, and an elastomeric cover layer.
Claim 5
Dependent Claim
75 words
A hydraulic brake hose comprising a polychloroprene core tube, a reinforcing braid of twisted, resorcinol-formaldehyde, latex coated glass fibers around said tube braided at an angle of about 52° to 56° to the axis of the tube, an elastomeric cushion layer over said glass braid, a reinforcing, untwisted braid of nylon fibers over said cushion layer braided at an angle of 40° to 60° to the axis of the tube, and a polychloroprene cover layer.
Claim 6
Dependent Claim
75 words
A hydraulic brake hose comprising a polychloroprene core tube, a reinforcing braid of twisted, resorcinol-formaldehyde, latex coated glass fibers around said tube braided at an angle of about 52° to 56° to the axis of the tube, an elastomeric cushion layer over said glass braid, a reinforcing, untwisted braid of nylon fibers over said cushion layer braided at an angle of 40° to 60° to the axis of the tube, and a polychloroprene cover layer.
