Claim 1
Independent Claim
155 words
THE METHOD OF MANUFACTURE OF HOLLOW WAVEGUIDE COMPONENTS, COMPRISING PREPARING A MANDREL WITH AN EXTERIOR SHAPE CORRESPONDING TO THE INTERNAL CONFIGURATION DESIRED OF THE WAVEGUIDE COMPOENT, WINDING A TIGHTLY FITTING SPIRAL OF METAL WIRE UPON SAID MANDREL, ASSEMBLING FLANGED FITTINGS TO THE TERMINAL ENDS OF SAID SPIRAL, SECURING SAID SPIRAL AND FITTINGS TO SAID MANDREL BY MEANS OF REMOVABLE CLAMPS, PLACING FILLER METAL UPON THE OUTER SURFACE OF SAID SPIRAL AND ADJACENT SAID FITTINGS, IMMERSING SAID MANDREL WITH SAID SPIRAL AND FITTINGS CLAMPED THERETO IN A BATH OF FLUX AT A TEMPERATURE SUFFICIENTLY ELEVATED TO LIQUEFY SAID FILLER METAL BUT BELOW THE MELTING POINT OF SAID METAL WIRE, REMOVING SAID MANDREL, SPIRAL, FITTINGS AND ADHERENT FILLER METAL FROM SAID BATH, COOLING SAID MANDREL, SPIRAL AND FITTINGS TO CAUSE THE ADHERENT FILLER METAL TO SOLIDIFY AND THEREBY SECURE SAID SPIRAL AND SAID FITTINGS IN RIGID FORM, AND REMOVING SAID CLAMPS AND MANDREL FROM SAID RIGID SPIRAL.
