Abstract
Abstract An improved technique for providing electrical power to a fuel dispensing nozzle is disclosed. A plurality of conductive bands are installed around a cylindrical member, and conductive plungers and the fuel dispensing nozzle make contact with the conductive bands. As the fuel dispensing hose is twisted with respect to the nozzle, the conductive bands rotate but nonetheless remain in contact with the conductive plungers, thereby providing uninterrupted power to any desired electronics installed within the fuel dispensing nozzle.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
68 words
A fuel dispensing apparatus comprising: a nozzle, said nozzle including; a valve housing a valve coupling portion for connecting to a fuel dispensing hose; one conductive plunger disposed on the valve coupling portion and resiliently tending to expand away from said valve coupling portion such that it remains in contact with a conductive band placed against said conductive plunger despite variations in the surface of said conductive band.
Claim 2
Dependent Claim
68 words
A fuel dispensing apparatus comprising: a nozzle, said nozzle including; a valve housing a valve coupling portion for connecting to a fuel dispensing hose; one conductive plunger disposed on the valve coupling portion and resiliently tending to expand away from said valve coupling portion such that it remains in contact with a conductive band placed against said conductive plunger despite variations in the surface of said conductive band.
Claim 3
Dependent Claim
80 words
A fuel dispensing apparatus comprising a nozzle according to claim 1, said apparatus further comprising: a fuel dispensing hose, said fuel dispensing hose comprising: a member for mating with said valve coupling portion; at least one conductive band, each of said conductive bands being affixed to the outer perimeter of said member; and a connecting collar attaching the fuel dispensing hose to the valve coupling portion, thereby placing said conductive bands in contact with said at least one conductive plunger.
Claim 4
Dependent Claim
19 words
The fuel dispensing apparatus of claim 2, wherein said conductive bands span the entire outer perimeter of said member.
Claim 5
Dependent Claim
12 words
The fuel dispensing apparatus of claim 3, wherein said member is cylindrical.
Claim 6
Dependent Claim
26 words
The fuel dispensing nozzle of claim 5 wherein said electrical connector comprises a plurality of stubs thereon for connecting to conductors within the fuel dispensing nozzle.
Claim 7
Dependent Claim
50 words
The fuel dispensing apparatus of claim 4 further comprising an electrical connector for mounting said conductive plungers, said electrical connector further comprising a separate conductor connected to each of said conductive plungers and routing an electrical signal from said conductive plunger, through said connector and into said fuel dispensing nozzle.
Claim 8
Dependent Claim
20 words
The fuel dispensing apparatus of claim 4 wherein said fuel dispensing hose comprises an inner channel and an outer channel.
Claim 9
Dependent Claim
19 words
The fuel dispensing apparatus of claim 4 wherein said fuel dispensing nozzle comprises: an electronic display for displaying data.
Claim 10
Dependent Claim
27 words
The fuel dispensing arrangement according to claim 7 further comprising data input means attached to said fuel dispensing nozzle for allowing a user to enter digital data.
Claim 11
Dependent Claim

Claim 12
Dependent Claim
69 words
A fuel dispensing apparatus comprising: a cylindrical dispensing hose, said hose including a plurality of conductive bands therearound; a dispensing nozzle, said nozzle including a valve connecting portion for coupling to said dispensing hose; a plurality of conductive plungers inside said valve connecting portion and disposed such that when said dispensing hose is fully connected to said dispensing nozzle, said conductive plungers are in contact with said conductive bands.
Claim 13
Dependent Claim
69 words
A fuel dispensing apparatus comprising: a cylindrical dispensing hose, said hose including a plurality of conductive bands therearound; a dispensing nozzle, said nozzle including a valve connecting portion for coupling to said dispensing hose; a plurality of conductive plungers inside said valve connecting portion and disposed such that when said dispensing hose is fully connected to said dispensing nozzle, said conductive plungers are in contact with said conductive bands.
Claim 14
Dependent Claim
37 words
The fuel dispensing apparatus of claim 11 wherein said fuel dispensing hose includes a connecting collar, said connecting collar including a plurality of threads thereon and being freely rotatable about the longitudinal axis of said dispensing hose.
Claim 15
Dependent Claim
19 words
Apparatus of claim 12 wherein said fuel dispensing hose and said nozzle each comprise an inner and outer channel.
