Abstract
Abstract A multi-wire conduit dam consisting of a molded strip of closed cell sponge rubber or equivalent that is shaped like a timing belt having recesses on at least one side with the recessed surface coated with adhesive or double sided adhesive tape after wires are placed in the recesses. The strip is then rolled together to form a cylindrical dam which may then be installed in an appropriate conduit.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
A multi-wire conduit dam comprising: a. a molded strip of compressible material rolled into a cylinder and having a plurality of recesses on at least one side of said strip, b. at least one electrical conductor positioned in a respective one of said recesses prior to the formation of said cylinder, c. an adhesive placed over said recesses and said at least one conductor to cause said strip to hold its shape when said strip is rolled into said cylinder, and d. a smooth surface tape applied to the outside of said rolled cylinder for allowing easy insertion of said cylinder with said at least one conductor into a conduit to form a conduit dam.
Claim 2
Dependent Claim
115 words
A multi-wire conduit dam comprising: a. a molded strip of compressible material rolled into a cylinder and having a plurality of recesses on at least one side of said strip, b. at least one electrical conductor positioned in a respective one of said recesses prior to the formation of said cylinder, c. an adhesive placed over said recesses and said at least one conductor to cause said strip to hold its shape when said strip is rolled into said cylinder, and d. a smooth surface tape applied to the outside of said rolled cylinder for allowing easy insertion of said cylinder with said at least one conductor into a conduit to form a conduit dam.
Claim 3
Dependent Claim
25 words
A multi-wire conduit dam as in claim 1 wherein said plurality of recesses are equally spaced along said at least one side of said strip.
Claim 4
Dependent Claim
17 words
A multi-wire conduit dam as in claim 2 wherein said adhesive is a double sided adhesive tape.
Claim 5
Independent Claim
115 words
A method of forming a multi-wire conduit dam comprising the steps of: a. rolling a molded strip of compressible material into a cylinder, said strip having a plurality of recesses on at least one side of said strip, b. positioning at least one electrical conductor in a respective one of said recesses, c. placing an adhesive over said recesses and said at least one conductor to cause said strip to hold its shape when said strip is rolled into said cylinder, and d. applying a smooth surface tape to the outside of said rolled cylinder for allowing easy insertion of said cylinder with at least one conductor into a conduit to form a conduit dam.
Claim 6
Independent Claim
115 words
A method of forming a multi-wire conduit dam comprising the steps of: a. rolling a molded strip of compressible material into a cylinder, said strip having a plurality of recesses on at least one side of said strip, b. positioning at least one electrical conductor in a respective one of said recesses, c. placing an adhesive over said recesses and said at least one conductor to cause said strip to hold its shape when said strip is rolled into said cylinder, and d. applying a smooth surface tape to the outside of said rolled cylinder for allowing easy insertion of said cylinder with at least one conductor into a conduit to form a conduit dam.
Claim 7
Dependent Claim
26 words
A method as in claim 4 further comprising the step of equally spacing said plurality of recesses on said at least one side of said strip.
Claim 8
Dependent Claim
20 words
A method as in claim 5 further comprising the step of using a double sided adhesive tape as said adhesive.
Claim 9
Independent Claim
120 words
A method of forming a multi-wire conduit dam comprising the steps of: a. forming a molded strip of compressible material having a plurality of recesses on at least one side of said strip, b. placing at least one electrical conductor in a respective one of said recesses, c. covering said strip and said at least one conductor with double sided adhesive tape, d. rolling said strip with said conductor in said recess into a cylinder which is held in shape by said double sided adhesive tape, and e. wrapping a smooth surface tape around the outside of said cylinder for allowing easy insertion of said cylinder with said at least one conductor into a conduit to form a conduit dam.
Claim 10
Independent Claim
120 words
A method of forming a multi-wire conduit dam comprising the steps of: a. forming a molded strip of compressible material having a plurality of recesses on at least one side of said strip, b. placing at least one electrical conductor in a respective one of said recesses, c. covering said strip and said at least one conductor with double sided adhesive tape, d. rolling said strip with said conductor in said recess into a cylinder which is held in shape by said double sided adhesive tape, and e. wrapping a smooth surface tape around the outside of said cylinder for allowing easy insertion of said cylinder with said at least one conductor into a conduit to form a conduit dam.
