Abstract

436,078. Discharge apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. March 1, 1934, No. 6610. Convention date, March 3, 1933. Drawings to Specification. [Class 39 (i)] [See also Group XI] The Specification as open to inspection under Sect. 91 describes the arrangement and interconnection of internal parts such as pole wires, incandescent bodies, screens, &c. of rectifying tubes and glow discharge tubes, in such a manner that the natural frequency of vibration of the interconnected parts has a value sufficiently high to prevent the vibrations of the surroundings in which the device is used from exerting any unfavourable effect. This subjectmatter does not appear in the Specification as accepted.
