Abstract

1,056,038. Dry shavers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Nov. 3, 1964 [Nov. 6, 1963], No. 44745/64. Heading B4B. [Also in Divisions B6 and G2] Shear plates for electric dry shavers are produced by coating a flat stainless steel plate with a photo-resist, exposing through a mask with the desired apertures, removing the unhardened parts of the resist to bare the steel, bending the plate to the desired shape and etching through the steel and removing the hardened parts by burning off to obtain the shear plates. Preferably, the shear plate is hardened by heating to 1,020‹ C., cooled rapidly, immersed in liquid air and tempered at 200‹ C.
