Abstract
Abstract A sheet metal waveguide includes a pair of sheet metal channels with each channel having a double bend or fold along each of two substantially parallel leg sections. The channels are arranged relative to each other such that a portion of a leg suction of one channel overlaps a portion of a leg section of the other channel in a manner to form a waveguide having recesses on opposite broad walls thereof suitable for receiving and holding a dielectric body therebetween. The ends of the leg sections of one channel are clipped and thereby held within a bend or fold in the leg sections of the other channel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
131 words
A waveguide comprising: a pair of sheet metal channel members each having a pair of substantially parallel leg sections spaced by a substantially perpendicular center section, each of said leg sections having a recessed inner surface portion formed by a portion of each leg section being bent so as to fold twice on itself, a dielectric body, said channel members being arranged such that said recessed inner surface portions overlap each other to form a section of waveguide having recesses on each of the opposite broad walls of the waveguide adapted to receive said body with said channel members being interlocked to each other by the ends of the leg sections of one channel member being fitted individually into the respective folds in the leg sections of the other channel member.
Claim 2
Dependent Claim
131 words
A waveguide comprising: a pair of sheet metal channel members each having a pair of substantially parallel leg sections spaced by a substantially perpendicular center section, each of said leg sections having a recessed inner surface portion formed by a portion of each leg section being bent so as to fold twice on itself, a dielectric body, said channel members being arranged such that said recessed inner surface portions overlap each other to form a section of waveguide having recesses on each of the opposite broad walls of the waveguide adapted to receive said body with said channel members being interlocked to each other by the ends of the leg sections of one channel member being fitted individually into the respective folds in the leg sections of the other channel member.
Claim 3
Dependent Claim
43 words
A waveguide as claimed in claim 1 wherein said body is a toroid of magnetic material, a wire running through the center of said toroid to which a direct current potential can be applied for establishing a desired magnetic field in said toroid.
Claim 4
Dependent Claim
129 words
A waveguide comprising: first and second sheet metal channel members each having a pair of substantially parallel leg sections separated by a center section, each leg section including a stepped portion formed by first bending the leg section at a point along its length back towards the center section and then bending the leg section at said point back to the original direction of said leg section thereby forming a double bend, the inside fold of the second bend so formed facing away from said center section, said channel members being interlocked by overlapping the stepped portions of the leg sections with the ends of the leg sections of one channel member being fitted individually into the respective second bends in the leg sections of the other channel member.
Claim 5
Dependent Claim
129 words
A waveguide comprising: first and second sheet metal channel members each having a pair of substantially parallel leg sections separated by a center section, each leg section including a stepped portion formed by first bending the leg section at a point along its length back towards the center section and then bending the leg section at said point back to the original direction of said leg section thereby forming a double bend, the inside fold of the second bend so formed facing away from said center section, said channel members being interlocked by overlapping the stepped portions of the leg sections with the ends of the leg sections of one channel member being fitted individually into the respective second bends in the leg sections of the other channel member.
Claim 6
Independent Claim
164 words
The method of making a waveguide including a dielectric body comprising the steps of: forming a pair of channel shaped members each having a pair of substantially parallel leg sections and an intermediate orthogonal center section, bending a portion of each leg section such that each leg section is twice bent on itself in a manner to form a recess along a portion of each leg section and so that the inner surface of the second bend faces away from said center section, overlapping the recessed portions of the leg sections of one channel member with the recessed portions of the leg sections of the other channel member to form a section of waveguide with recesses on each of opposite walls of the waveguide adapted to receive opposite ends of said body, and interlocking said channel members by fitting the ends of the leg sections of one channel member individually into the respective second bends in the leg sections of the other channel member.
