Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
110 words
A method for making a fluid control device having a tubular fluid passageway therein comprising: a. providing a plate member, b. coining into the surface of the plate member a length of hard drawn wire having an appropriate form, c. removing the length of wire so as to leave a channel therein generally conforming to the form of the wire, d. applying to the plate member a cover member of sufficient dimension to cover the channel, e. thereby forming a tubular fluid passageway in the fluid control device, and including the step of f. providing means in said device for providing fluid access to said passageway from an external source.
Claim 2
Independent Claim
110 words
A method for making a fluid control device having a tubular fluid passageway therein comprising: a. providing a plate member, b. coining into the surface of the plate member a length of hard drawn wire having an appropriate form, c. removing the length of wire so as to leave a channel therein generally conforming to the form of the wire, d. applying to the plate member a cover member of sufficient dimension to cover the channel, e. thereby forming a tubular fluid passageway in the fluid control device, and including the step of f. providing means in said device for providing fluid access to said passageway from an external source.
Claim 3
Independent Claim
130 words
A method for making a fluid control device having a tubular fluid passageway therein comprising: a. providing a plate member, b. bending a length of hard drawn wire in the form of the passageway, c. positioning said length of hard drawn wire on the surface of the plate member in coincidence with the place where the passageway is to be formed, d. coining said length of hard drawn wire into said surface, e. removing said length of hard drawn wire, f. applying to the plate member a cover member of sufficient dimension to cover the passageway, g. thereby forming a tubular fluid passageway in the fluid control device, and including the stEp of h. providing means in the device for providing fluid access to said passageway from an external source.
Claim 4
Independent Claim
130 words
A method for making a fluid control device having a tubular fluid passageway therein comprising: a. providing a plate member, b. bending a length of hard drawn wire in the form of the passageway, c. positioning said length of hard drawn wire on the surface of the plate member in coincidence with the place where the passageway is to be formed, d. coining said length of hard drawn wire into said surface, e. removing said length of hard drawn wire, f. applying to the plate member a cover member of sufficient dimension to cover the passageway, g. thereby forming a tubular fluid passageway in the fluid control device, and including the stEp of h. providing means in the device for providing fluid access to said passageway from an external source.
Claim 5
Independent Claim
155 words
A method for making a fluid control device having a tubular fluid passageway therein comprising: a. providing a plate member, b. providing a press matrix, c. coining a length of hard drawn wire having an appropriate form partially into the surface of the press matrix so as to provide a projection on the surface of the press matrix in the form of the passageway, d. pressing together the surface of the press matrix and the surface of the plate member, e. removing the press matrix and the wire so as to leave a channel in the surface of the plate member generally conforming to the form of the wire, f. applying to the plate member a cover member of sufficient dimension to cover the channel, g. thereby forming a tubular fluid passageway in the fluid control device, and h. providing means in the device for providing fluid access to the passageway from an external source.
Claim 6
Independent Claim
155 words
A method for making a fluid control device having a tubular fluid passageway therein comprising: a. providing a plate member, b. providing a press matrix, c. coining a length of hard drawn wire having an appropriate form partially into the surface of the press matrix so as to provide a projection on the surface of the press matrix in the form of the passageway, d. pressing together the surface of the press matrix and the surface of the plate member, e. removing the press matrix and the wire so as to leave a channel in the surface of the plate member generally conforming to the form of the wire, f. applying to the plate member a cover member of sufficient dimension to cover the channel, g. thereby forming a tubular fluid passageway in the fluid control device, and h. providing means in the device for providing fluid access to the passageway from an external source.
Claim 7
Independent Claim
133 words
A method for making a fluid control device having a tubular fluid passageway therein comprising: a. providing a pair of plate members, b. positioning a length of hard drawn wire of an appropriate form between the two plate members, c. pressing the pair of plate members together in a registering position so as to coin the wire into the surface of at least one of the members, d. separating the plate members, e. removing the wire so as to leave a channel in the surface of at least one of the plate members, f. replacing the plate members together in the registering position, g. thereby forming a tubular fluid passageway in the fluid control device, and h. providing means in the device for providing fluid access to the passageway from an external source.
Claim 8
Independent Claim
133 words
A method for making a fluid control device having a tubular fluid passageway therein comprising: a. providing a pair of plate members, b. positioning a length of hard drawn wire of an appropriate form between the two plate members, c. pressing the pair of plate members together in a registering position so as to coin the wire into the surface of at least one of the members, d. separating the plate members, e. removing the wire so as to leave a channel in the surface of at least one of the plate members, f. replacing the plate members together in the registering position, g. thereby forming a tubular fluid passageway in the fluid control device, and h. providing means in the device for providing fluid access to the passageway from an external source.
Claim 9
Dependent Claim
24 words
A method as in claim 1 and wherein: a. the plate member is aluminum, and b. the hard drawn wire is a steel wire.
Claim 10
Dependent Claim
24 words
