Abstract: The object of the process is to obtain an intermediate short-circuiting ring in a squirrel cage rotor by filling. It makes use of the technique consisting in automatically cutting out and assembling rotor laminations by means of a follow-on machine in which the laminations are cut out from a strip, rotated through a determined angle and provided with half-cutouts for their assembly in a packet. The process consists in eliminating at least one tooth in every two from the laminations whose position in the packet corresponds to the situation of the intermediate short-circuiting ring, and turning these laminations through an angle such that when filling is effected a continuous annular zone of nonmagnetic material is obtained.

Abstract: Process for controlled dissolving of quartz and its application to the chemical machining of the thickness or of the shape of quartz laminae intended to form resonators. The dissolving solvents employed until now (hydrofluoric acid and ammonium bifluoride) are not satisfactory because they deteriorate the surface quality of the laminae. According to the invention it has been found that it is particularly advantageous to employ baths in which the main solvent is an alkali metal (lithium, potassium or sodium) fluoride or hydroxide or an ammonium hydroxide or a mixture of these compounds.
