Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
199 words
An assembly for effecting at least one electric connection through one pipe formed of a plurality of pipe elements secured to one another, each pipe element having a first end and a second end, adapted to mechanically cooperate with the complimentary ends of the next elements, characterized in that each pipe element comprises: a sheath placed inside said element and wherein is housed at least one conductor, a first connected secured to one end of said sheath which is maintained in the first end of said pipe element and which electrically cooperates with said conductor, a second connector secured to the other end of said sheath which is maintained in the second end of said pipe element and which electrically cooperates with said conductor, a double connector having a first end comprising at least one contact and a second end comprising at least one contact, said contacts being electrically connected to one another, the first end of said double connector electrically cooperating with the first connector of an adjacent pipe element, the second end of the double connector electrically cooperating with said second connector, and means for positioning and fastening said first and second connectors to said pipe element.
Claim 2
Dependent Claim
199 words
An assembly for effecting at least one electric connection through one pipe formed of a plurality of pipe elements secured to one another, each pipe element having a first end and a second end, adapted to mechanically cooperate with the complimentary ends of the next elements, characterized in that each pipe element comprises: a sheath placed inside said element and wherein is housed at least one conductor, a first connected secured to one end of said sheath which is maintained in the first end of said pipe element and which electrically cooperates with said conductor, a second connector secured to the other end of said sheath which is maintained in the second end of said pipe element and which electrically cooperates with said conductor, a double connector having a first end comprising at least one contact and a second end comprising at least one contact, said contacts being electrically connected to one another, the first end of said double connector electrically cooperating with the first connector of an adjacent pipe element, the second end of the double connector electrically cooperating with said second connector, and means for positioning and fastening said first and second connectors to said pipe element.
Claim 3
Dependent Claim
53 words
An assembly according to claim 1, wherein said second connector is placed and maintained in position in said pipe element by a pin having a certain length of conical shape and cooperating with a first conical bore provided in said second connector and with a second conical bore provided in said pipe element.
Claim 4
Dependent Claim
23 words
An assembly according to claim 2, wherein said pin is surmounted with a cylindrical part providing for the positioning of the double connector.
Claim 5
Dependent Claim
74 words
An assembly according to claim 1, wherein at least one of the second connector or the first connector is provided with at least one external groove connected to at least one hole, said hole extending through said at least one first or second connectors for achieving a pressure balance within the space defined by two complimentary ends of adjacent elements and by different parts allowing the electric connection with an interior of the pipe.
Claim 6
Dependent Claim
32 words
An assembly according to claim 4, wherein said at least one hole opens in a cavity having a shape adapted to reduce the wear of edges of said at least one hole.
Claim 7
Dependent Claim
42 words
An assembly according to claim 5, wherein a plurality of holes are provided along a same diameter, said plurality of holes opening into a cylindrical groove having a flat bottom and two sides at least one of which has a gentle slope.
Claim 8
Dependent Claim
37 words
An assembly according to claim 1, wherein the second connector is made of a rigid material to which is secured at least one conducting ring maintained in position by one of a thermal setting resin or elastomer.
Claim 9
Dependent Claim
35 words
An assembly according to claim 1, wherein the second connector at an upper part not secured to said other end of said sheath has a diameter larger than a smaller inner diameter of the pipe.
Claim 10
Dependent Claim

An assembly according to claim 1, wherein an external diameter of the first connector is at most equal to a smaller inner diameter of the pipe.
Claim 11
Dependent Claim
56 words
An assembly according to claim 1, wherein the means for positioning and fastening the first connector comprises at least one ball partially housed in a cavity provided inside the first end of the pipe element, at least one part maintaining said ball in said cavity, said part being maintained on the first connector by a bolt.
Claim 12
Dependent Claim
75 words
An assembly according to claim 10, wherein said part maintaining said ball comprises a bore throughout said part, said bore being threaded over at least a certain portion of a length thereof and being so positioned so as to face a solid rigid part of the first connector so that a force is applied which tends to disengage said part from the first connector when threadably inserting a bolt of sufficient length into said bore.
Claim 13
Dependent Claim
31 words
An assembly according to claim 1, wherein said double connector is maintained applied against said second connector through at least one screw screwing on the second end of the pipe element.
Claim 14
Dependent Claim

An assembly according to claim 1, wherein said double connector comprises housings receiving joints provided for the sealing of the electric contact between said double connector and the second connector.
Claim 15
Dependent Claim
22 words
An assembly according to claim 1, wherein the first end of the double connector is made of an elastomer comprising reinforcing elements.
Claim 16
Dependent Claim
32 words
An assembly according to claim 1, wherein the first end of the double connector comprises lips for drying and sealing of the electric contacts between the double connector and the first connector.
Claim 17
Dependent Claim
47 words
An assembly according to claim 15, wherein the first end of the double connector comprises free spaces in a vicinity of the lips, said free spaces being adapted to accommodate a volume of material displaced by a rearward movement of the lips when introducing the first connector.
Claim 18
Dependent Claim
26 words
An assembly according to claim 1, wherein the positioning of the second connector is effected by spacers interposed between the pipe element and said second connector.
Claim 19
Dependent Claim
33 words
An assembly according to claim 1, wherein the first connector comprises at least one housing adapted to receive a joint means for at least one of drying and sealing of the electric contact.
Claim 20
Dependent Claim
29 words
An assembly according to claim 1, wherein at least certain parts of at least one of said first, second, and double connectors exposed to are coated with antiwear material.
Claim 21
Dependent Claim
47 words
An assembly according to claim 1, wherein the means for positioning and fastening the first connector to the pipe element comprises at least one pin cooperating with a housing provided inside the pipe element and with a bore provided in the first connector and a retaining member.
