Abstract

550,694. Pressure gauges. B. & R. PATENTS, Ltd., and BIRCH, G. C. R. July 16, 1941, No. 9002. [Class 106 (ii)] [Also in Group XX] A hydraulic remote-indicating apparatus for a thermometer bulb A or other device connected by capillary tubing B to an indicator-controlling bellows H is compensated for temperature expansion or contraction of the liquid in the tubing and bellows by a second bellows E arranged at the side of the bellows H and by a second tube C adjacent the tube B, the lower ends of the two bellows being interconnected (for example, by toothed levers F, G) so that the position of the indicator-operating connection 11 remains unaffected by ambient temperature changes and moves only in response to changes in the thermometer bulb or other device. The lengths of the levers F, G are adjustable to meet any dissimilarity in the two bellows. The end covers E2, H2 of the bellows may be re-entrant to reduce the quantity of liquid contained therein.
