Abstract

430,943. Pressure gauges. DODDS, E. M., 12, Swiss Avenue, Watford, Hertfordshire. July 13, 1934, No. 20600. [Class 106 (ii)] [See also Group XXXVIII] A diaphragm device and resistance combined in the form of a sparking plug are arranged in circuit with a cathode ray oscillograph so that deflections of the ray in one direction is responsive to the pressure in the cylinder. An outer stainless steel shell 60 is formed with a diaphragm 61. Centrally arranged is a stainless steel member 65 formed with a recess 62 enclosing a pile of carbon discs 63 insulated from the members by a sleeve 64 of mica &c. The member 65 is held by a screwed bush 66 insulated from the outer shell. A locking ring 71 secures the device after adjustment. Passages 711 may be provided for circulation of cooling water. In a modification substituted for the carbon discs are others made from a resistance powder containing powdered mica to prevent " packing." Specification 430,974 is referred to.
