Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
121 words
A method for fixturing two or more workpieces in a desired positional relationship to one another for the heat effected joining of same comprising in the following order the steps of: a. depositing a quantity of moldable, heat resistance workpiece holding material on a work surface; b. inserting portions of each of the workpieces to be joined into said holding material with portions thereof to be heated left exposed; c. moving the inserted workpieces to the desired positional relationship with one another by adjusting the relative positions of the workpieces; and d. manipulating said holding material for conformance to the contours of the inserted portions of the workpieces whereby said workpieces can be joined by heat effected means such as welding.
Claim 2
Independent Claim
121 words
A method for fixturing two or more workpieces in a desired positional relationship to one another for the heat effected joining of same comprising in the following order the steps of: a. depositing a quantity of moldable, heat resistance workpiece holding material on a work surface; b. inserting portions of each of the workpieces to be joined into said holding material with portions thereof to be heated left exposed; c. moving the inserted workpieces to the desired positional relationship with one another by adjusting the relative positions of the workpieces; and d. manipulating said holding material for conformance to the contours of the inserted portions of the workpieces whereby said workpieces can be joined by heat effected means such as welding.
Claim 3
Dependent Claim
26 words
The method as recited in claim 1, wherein the step of fixing comprising simultaneously adjusting the position of the workpieces and manipulating the work holding material.
Claim 4
Dependent Claim
36 words
The method as recited in claim 1 or claim 2, further including the steps of removing the fixed workpieces from the holding material, hardening the holding material and reinserting the workpieces into the hardened holding material.
Claim 5
Dependent Claim
37 words
The method as recited in claim 3, wherein the step of hardening comprises heating the holding material to a temperature of approximately 120° C. and maintaining the holding material at said temperature for 1 to 3 hours.
Claim 6
Dependent Claim
25 words
The method as recited in claim 1, wherein the step of depositing comprises providing workpiece holding material capable of remaining dimensionally stable at elevated temperatures.
Claim 7
Dependent Claim
25 words
The method as recited in claim 5, wherein the workpiece holding material is provided by mixing a ceramic material, a binder and a thickening agent.
Claim 8
Dependent Claim
43 words
The method as recited in claim 6, wherein the step of mixing comprises providing alumina silica fibers having approximately 50% Al 2 O 3 and 50% SiO 2 , said fibers having a length of 5 to 7.5 cm. as the ceramic material.
Claim 9
Dependent Claim
24 words
The method as recited in claim 5 comprising providing a workpiece holding material mixture including a ceramic material, a binder and a thickening agent.
Claim 10
Dependent Claim
41 words
The method as recited in claim 8, wherein the mixture comprises providing alumina silica fibers having approximately 50% Al 2 O 3 and 50% SiO 2 , said fibers having a length of 5 to 7.5 cm. as the ceramic material.
Claim 11
Independent Claim
130 words
A method for fixturing two or more workpieces in a desired positional relationship to one another for the heat effected joining of some comprising in the following order the steps of: a. depositing a quantity of moldable, heat resistant workpiece holding material on a work surface by discharging the holding material from a syringelike device; b. inserting portions of each of the workpieces to be joined into the holding material with portions thereof to be heated left exposed c. moving the inserted workpieces to the desired positional relationship with one another by adjusting the relative positions of the workpieces; and d. manipulating the holding material for conformance to the contours of the inserted portions of the workpieces whereby said workpieces can be joined by heat effected means such as welding.
