Abstract

524,436. Casting electric components. PHILIPS LAMPS, Ltd. Sept. 7, 1939. No. 25271. Convention date. Sept. 6. 1938. [Class 83 (i)] [Also in Groups V, XXXVI and XL] Casting composite articles. - Radio - receiving or other electric apparatus having its conductor system die-cast as in Specification 515,354, wherein at least one of the connections 3, 4 to resistance material 2 is an integral part of the cast system. If the resistance material and the conductor system are carried by plates 12, 17, Fig. 4, a lead 10, forming part of the cast system 15, may pass through aligned holes in the plates and engage the resistance material 2. The connection to the other end of the material 2 may be made similarly or, when the material is arranged along a spiral as shown, it may surround a part or the whole of the plate 12 as shown at 16.
