Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
26 words
The method as set forth in claim 1 in which said solder is a zinc base alloy comprising up to about 10 percent aluminum by weight.
Claim 2
Dependent Claim
40 words
The method as set forth in claim 1 in which said solder is a zinc base alloy comprising about 2 percent to 5 percent aluminum, up to about 5 percent copper, and up to about 1 percent magnesium by weight.
Claim 3
Dependent Claim
21 words
The method as set forth in claim 1 in which said steps of heating and relatively moving are accomplished substantially simultaneously.
Claim 4
Dependent Claim
53 words
The method as set forth in claim 1 in which said components have interior passageways of substantially the same cross-sectional size and shape, including the step of enlarging an end portion of one component to provide an inner surface adapted to receive said outer surface of the other component with their passageways aligned.
Claim 5
Dependent Claim
24 words
The method as set forth in claim 5 including enlarging said end portion to provide a substantially cylindrical inner surface extending axially inwardly thereof.
Claim 6
Dependent Claim
19 words
The method of claim 5 including enlarging said end portion to provide an inner surface having a frustoconical configuration.
Claim 7
Dependent Claim
49 words
A method of joining at least one of the substantially parallel legs of a tubular return bend component to a corresponding tubular element as set forth in claim 1, without rotating said component, wherein said moving comprises axially relatively moving said element and component while maintaining said firm contact.
Claim 8
Dependent Claim
53 words
A method of concurrently joining each of the substantially parallel legs of a tubular return bend component to an end of corresponding tubular hairpin components as shown in FIG. 2, by the method of claim 1, wherein said moving comprises relatively moving said components lengthwise of said legs while maintaining said firm contact.
Claim 9
Dependent Claim
53 words
The method of claim 1 wherein the providing of said tubular components includes providing one component having a bell end and the other having a spigot end, said components being adapted for assembly in telescoping relationship by forcing an outer surface of said spigot end into an inner surface of said bell end.
Claim 10
Dependent Claim
53 words
The method as set forth in claim 10 in which, both of said components are made of aluminum or aluminum alloy, and, said step of providing a solid coating of solder comprises providing a solid coating on both the inside surface of said bell end and the outside surface of said spigot end.
Claim 11
Dependent Claim
17 words
The method as set forth in claim 11 in which said solder comprises a zinc base alloy.
Claim 12
Dependent Claim
44 words
The method as set forth in claim 10 in which the inside surface of said bell end and the outside surface of said spigot end are dimensioned so as to provide an interference fit prior to the application of said solid coating of solder.
Claim 13
Dependent Claim
55 words
The method as set forth in claim 13 in which said inside surface of said bell end has a substantially cylindrical configuration having a given diameter and said outside surface of said spigot end has a cooperating substantially cylindrical configuration and a diameter which is larger than said given diameter to provide said interference fit.
Claim 14
Dependent Claim
34 words
The method as set forth in claim 13 in which said bell end has an outwardly flaring inlet portion which enables an associated spigot end To be installed in position in an easier manner.
Claim 15
Dependent Claim
26 words
The method as set forth in claim 13 in which said step of relatively moving comprises relatively axially moving said spigot end within said bell end.
Claim 16
Dependent Claim
25 words
The method as set forth in claim 13 in which said step of relatively moving comprises relatively rotating said spigot end within said bell end.
Claim 17
Dependent Claim
27 words
The method as set forth in claim 13 in which said step of relatively moving comprises imparting relative radial movement between said spigot end and bell end.
Claim 18
Dependent Claim
59 words
The method as set forth in claim 13 in which said solder is a zinc base alloy comprising about 2 to 5 percent aluminum, up to about 5 percent copper, and up to about 1 percent magnesium by weight, said solid coating of solder having a thickness generally of the order of a few ten thousandths of an inch.
Claim 19
Independent Claim
157 words
The method of joining pretinned tubular components having interior passageways of substantially the same cross-sectional size and shape, at least one of said components being made of aluminum or aluminum alloy, comprising the steps of: enlarging an end portion of one component to form a substantially cylindrical inner surface extending axially inwardly thereof, adapted to receive an outer peripheral surface of the other component with their passageways aligned, and having a smaller diameter than said outer surface; providing said components with a solid coating of solder on each of said surfaces, said coatings affording all of the solder needed for said joining; heating said components to melt the solder; relatively moving said components in telescoping relationship; progressively increasing the axial overlap of said surfaces; maintaining both components in firm contact with the melted solder in a region of said increasing overlap at the desired location for bonding; and cooling the melted solder to bond said components together.
