17,116. Schultze, P., and Gaehde, T., [trading as Schultze, G. A., [Firm of]], and Dosch, A. Aug. 14. Pressure gauges.-A gas-pressure gauge comprising a closed chamber a within which a certain pressure is permitted access to two pressure-indicating elements c, c<1>, exposed on their opposite surfaces to gas at a higher and lower pressure respectively than that in the casing. These two elements actuate pointers h, h<1>, which move in the same direction over the same scale to indicate the difference in pressure between the two supplies i, l and the steady pressure-source k. The bell-floats c, c' shown in Fig. 1 may be replaced by flexible chambers expansible under pressure.
