Induction heating for adhesive bonding
First Claim
1. Apparatus bonding together an assembly of a first and second member, each member having a face surface adjacent the other member and an adhesive which can be thermally set interposed between said face surfaces, said apparatus comprising:
- (a) a plurality of small discreet spherical metal particles of predetermined diameter interposed between said face surfaces and interspaced within said adhesive;
(b) means for moving said face surface of said first member towards said face surface of second member until a substantially single layer of said particles are firmly grasped between said face surfaces to control the spacing between said face surface to a distance equal to said predetermined diameter; and
(c) means for inductively heating said particles whereby said adhesive is thermally set.

Abstract
A method and apparatus is disclosed for obtaining an improved bond between two structural members. Spherical particles, preferably graded steel shot, are interspersed within the adhesive and move in sliding and rolling contact relative to one another to establish an accurate space between opposing face surfaces of the structural members as the structural members are brought into pressured contact with one another. An induction coil may then be used to accurately heat the spherical particles and thus establish a heat source to thermally set the adhesive from within the spaced gap between the structural members established by the spherical particles.

10. A method of bonding together an assembly of a first and second member having opposed face surfaces to be secured to one another, said method comprising the steps of:
-
(a) providing a thermal setting adhesive to a portion of at least one of the member'"'"'s face surfaces; (b) mixing a plurality of shot having magnetic characteristics with said adhesive; (c) bringing said opposing face surfaces of said members together to dispense said shot within said adhesive into a general layer of single shot thus establishing a spacing equal to the diameter of the shot between said opposing face surfaces; (d) heating said shot by induction heating whereby said shot conveys sufficient heat to thermally set said adhesive and bond said members to one another. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method of bonding together of a first and second member in an accurate relationship comprising the steps of:
-
(a) providing an adhesive to a portion of one of the member'"'"'s face surfaces; (b) mixing a plurality of small, generally spherical particles within said adhesives; (c) pressing said face surfaces together to cause said particles to roll relative to one another into generally a single layer of said particles between said face surfaces to establish a desired space relationship; and (d) maintaining said surfaces in said spaced relationship until said adhesive has set. - View Dependent Claims (22)
