Abstract

480,666. Piezo - electric crystals. STANDARD TELEPHONES. & CABLES, Ltd. Jan. 8, 1937, No. 32720. Convention date, Jan. 30, 1936. Divided out of 615 /37. Drawings to Specification. [Class 40 (v)] An elongated piezo-electric crystal is supported inside a glass casing by resiliently mounted points located near the centres of opposite faces of the crystal. It is packed with frayed natural silk or the like as a precaution against displacement during transport. The subject-matter is described. in Specification 615/37, as open to inspection under Sect. 91, with reference to Figs. 5 to 9 (Cancelled) thereof.
