Abstract
Abstract The method of signal transfer by multi-point distributor heads using a multiplicity of individually insulated conductive members and applying an electrical signal to the conductive members selectively from one side of the head by means of stylii adapted to impress or receive a signal, the other side of the head being in contact with a web either adapted to receive a signal or containing a signal.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
124 words
The method of signal transfer by multi-point distributor heads comprising, forming a head of insulating material with a multiplicity of individually insulated conductive members extending therethrough, applying an electrical signal to the said conductive members selectively from one side of the head, receiving the signal on the said conductive members at the other side of the said head, one side of the said head being in contact with stylii to impress or receive a signal and the other side of the said head being in contact with a web either adapted to receive a signal or containing a signal and providing relative motion between said head and stylii to cause the head to be scanned by the stylii which successively contact said conductive members.
Claim 2
Independent Claim
124 words
The method of signal transfer by multi-point distributor heads comprising, forming a head of insulating material with a multiplicity of individually insulated conductive members extending therethrough, applying an electrical signal to the said conductive members selectively from one side of the head, receiving the signal on the said conductive members at the other side of the said head, one side of the said head being in contact with stylii to impress or receive a signal and the other side of the said head being in contact with a web either adapted to receive a signal or containing a signal and providing relative motion between said head and stylii to cause the head to be scanned by the stylii which successively contact said conductive members.
Claim 3
Dependent Claim
61 words
The method of claim 1 wherein the head is formed as a rotatable drum having the insulated conductive members projecting through its wall, the conductive members being contacted by stylii on a manifold within the drum, and rotating the drum while pressing the web against the outside of the drum to move the web and drum at the same linear speed.
Claim 4
Dependent Claim
36 words
The method of claim 2 wherein the web is an insulator or photoconductive member which receives electrical signals impressed by the stylii on the web, and developing said signals on said web to render same translatable.
Claim 5
Dependent Claim
22 words
The method of claim 2 wherein the web contains a conductive image which is transmitted to said stylii by said conductive members.
Claim 6
Dependent Claim
59 words
The method of claim 1 wherein the head is formed as a rotatable drum having the insulated conductive members projecting through its wall, the conductive members being contacted by stylii on a manifold within the drum, rotating the drum, contacting the periphery of the drum with a developer, and transferring the developed signal from the drum to a web.
Claim 7
Dependent Claim
58 words
The method of claim 1 wherein the head is formed as a rotatable drum having the insulated conductive members projecting through its wall, the conductive members being contacted on one side of the platen by stylii on a manifold, moving the manifold and stylii across the platen, and pressing the web against the other side of the platen.
Claim 8
Dependent Claim
25 words
The method of claim 6 wherein the web receives signals transmitted from the stylii, and developing said signals on said web to render same translatable.
Claim 9
Dependent Claim
22 words
The method of claim 6 wherein the web contains a conductive image which is transmitted to said stylii by said conductive members.
Claim 10
Independent Claim
77 words
A device for receiving or recording signals comprising, a head having a multiplicity of individually insulated conductive members extending therethrough, stylii positioned for contacting said head on one side thereof, means for providing relative movement between said head and said stylii and means to press a web against the other side of said head whereby signals are transmitted between said stylii and said web through said conductive members when relative movement exists between said head and stylii.
Claim 11
Independent Claim
77 words
A device for receiving or recording signals comprising, a head having a multiplicity of individually insulated conductive members extending therethrough, stylii positioned for contacting said head on one side thereof, means for providing relative movement between said head and said stylii and means to press a web against the other side of said head whereby signals are transmitted between said stylii and said web through said conductive members when relative movement exists between said head and stylii.
Claim 12
Dependent Claim
38 words
A device according to claim 9 wherein the head is a drum having the conductive members extending through its wall, said stylii contacting the inner surface of said drum, said web contacting the outer surface of said drum.
Claim 13
Dependent Claim
37 words
A device according to claim 9 wherein the head is a platen having the conductive members extending through it, the said stylii contacting the platten on one side, said web contacting the other side of said platten.
Claim 14
Dependent Claim
91 words
A device according to claim 9 wherein the head comprises a wall of insulating material, a multiplicity of said conductive members being set in said wall to extend substantially from one face of the wall to the other, said stylii being supported in a row extending across said head to effect signal exchange between said stylii and said conductive members, said means which effects relative movement between said stylii and said head being constructeD to produce such relative movement in a direction substantially at right angles to said row of stylii.
Claim 15
Dependent Claim
96 words
A device according to claim 9 wherein the head comprises a wall of insulating material, a plurality of said conductive members being set in said wall to extend from one face of said wall through said other face, said stylii being supported in a row extending across said head on the side thereof where the conductive members extend, whereby said stylii contact said conductive members, said means which effects relative movement between said stylii and said head being constructed to produce such relative movement in a direction substantially at right angles to said row of stylii.
Claim 16
Dependent Claim
110 words
A device according to claim 9 wherein the head comprises a wall of insulating material, a plurality of said conductive members being set in said wall to extend from one face to near said other face of said wall, said stylii being supported in a row and extending across said head, whereby said stylii transfer signals through said head but without continuous contact between said stylii and the means on the other side of said head to which said signal is applied. sections because it would be possible for instance to have a voltage which could be sufficient to produce a similar problem as transmission through thedrum is by the
