Abstract

521,273. Pressure gauges. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MOSS, E. B. Nov. 10, 1938, No. 32743. [Class 106 (ii)] [Also in Group XXII] A capsule of the kind comprising two flexible corrugated diaphragms joined together at their peripheries have the corrugations so mated together that there is practically no space between them when the capsule is in the compressed condition. The capsule is produced from two blanks 10, 11 of identical dish-shape soldered at their peripheries 12, 13. a hole 14 being provided for communication to the interior. The assembly is then submitted to the action of press tools to form corrugations 15 which may be circular and V-shaped in section rounded top and bottom. The diaphragm may be joined together after corrugating and sealed by means other than soldering. A plurality of interconnected capsules may be employed in a stack and in this case the corrugations may be formed while they are superimposed in a single pressing operation.
