Abstract
Abstract An irradiated polyethylene tube is supported on a mandrel with adhesive material applied against its outside surface whereupon a first tubular layer is braided against the adhesive means followed by a tubular layer of neoprene rubber followed by braiding a second tubular layer against the neoprene rubber to define an assembly which is subjected to a controlled temperature environment to simultaneously vulcanize the rubber and bond the tube and tubular layers together defining the hose construction as a unitary structure.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
93 words
A hose construction comprising, an inner tube of irradiated-cured polyethylene, a layer of primer adjoining said tube with said primer layer having an affinity for cured polyethylene, a layer of adhesive on said layer of primer, at least one layer of tubular reinforcing material disposed against said layer of adhesive, said layers of primer and adhesive assuring a proper bond between said cured polyethylene tube and said braided layer, and a layer of vulcanized rubber adjoining said layer of tubular reinforcing material, said tube and said layers bonded together into a unitary structure.
Claim 2
Dependent Claim
93 words
A hose construction comprising, an inner tube of irradiated-cured polyethylene, a layer of primer adjoining said tube with said primer layer having an affinity for cured polyethylene, a layer of adhesive on said layer of primer, at least one layer of tubular reinforcing material disposed against said layer of adhesive, said layers of primer and adhesive assuring a proper bond between said cured polyethylene tube and said braided layer, and a layer of vulcanized rubber adjoining said layer of tubular reinforcing material, said tube and said layers bonded together into a unitary structure.
Claim 3
Dependent Claim
26 words
The hose construction of claim 1 in which said primer is a halogenated elastomeric based material and said adhesive is an ethylene propylene copolymer based material.
Claim 4
Dependent Claim
24 words
The hose construction of claim 1 and further comprising a second layer of tubular reinforcing material disposed around and against said layer of rubber.
Claim 5
Dependent Claim
17 words
The hose construction of claim 3 in which said tubular reinforcing material is formed of braided filaments.
Claim 6
Dependent Claim
14 words
The hose construction of claim 4 in which said filaments are formed of metal.
Claim 7
Dependent Claim
32 words
The hose construction of claim 4 in which the filaments of said first layer are formed of a material which is dissimilar to the material of the filaments of said second layer.
