Definitions
- My invention relates to the manufacture of electrical rectifiers of the type disclosed and claimed in Letters Patent of the United States, No. 1640335, granted to L. O. Gron- 4? dahl on August 23, 1927.
- One object of my invention is the provision of novel and improved means for producing metallic copper on the outer surface of the copper oxide in rectifiers of the type referred
- the treated blank is then placed in a bath of molten metal to reduce the outer layer of the oxide to copper.
- This molten metal may, for example, be molten lead, in whichcase the bath should be at a temperature of 500 C. to 600 C.
- the purpose of producin the layer of copper on the outer surface 0 the copper oxide is, of course, to make it possible to readily make electrical contact with the cuprous oxide.
- ide rectifiers involves removing the treated blanks from the oxidizing furnace to a second furnace maintained at approximately 500 to 600 (3., and quenching the blanks in water after they have reached approximagaly ne reason for maintaining the reducing bath of my invention at 500 to 600 C. is to make this bath serve the purpose also of the second furnace, so that the blanks may be uenched in water directly from the reducin ath.
- the process 0 producing a rectifier unit which consists in heating a copper blank to approximately 1000 C. to form cuprous oxide thereon, placing the treated blank in a bath of molten metal maintained at approximately 500 to 600 C. to reduce the outer surface of the oxide to copper, and then quenching the blank.
