Abstract

1436139 Soldering PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 Sept 1973 [13 Sept 1972] 42469/73 Heading B3R [Also in Division H2] Each hollow pin 1 of a lamp cap has a constriction 3 near the free end which just allows the current conductor 5 to protrude into the cavity 2, but stops the back-flow of molten solder towards the lamp cap. Solder 6 in the form of a helix or split ring rests in the cavity 2 and can be melted by a high frequency coil 7 while in a reducing atmosphere present in a hood 19, Fig. 3 (not shown), or, alternatively, by a flame.
