1,093,115. Making magnetic heads. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 28, 1965 [Dec. 31, 1964], No. 54937/65. Heading B3A. [Also in Division G5] A filling material 14, 15 (e.g. glass or enamel) is disposed in or adjacent to the gap between the two parts 9, 10 of a head and is heated to its melting point, and the two parts 9, 10 are then pressed together by means of dies 17, 18, with compressible wires 19 (e.g. of copper) disposed between a head part and the associated die with the object of obtaining a substantially uniform pressure over the surfaces defining the gap and hence a substantially uniform gapwidth. |
