Abstract

433,355. Condensers. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. Oct. 5, 1934, No. 28568. Convention date, Dec. 12, 1933. Drawings to Specification. [Class 38 (ii)] [See also Groups XL and XXXVI] A screening device for high-frequency apparatus or parts thereof is constructed of ceramic material which is insensitive to temperature change and is coated with metal for example by metallizing with copper or silver. The material " Ardostan " having a coefficient of linear expansion of 1.10<-6> may be used.
