A calibration system for a mechanical gas volume corrector which has a first shaft turned at a rate corresponding to the otherwise uncorrected volumetric flow rate through the meter, a second shaft, a variable ratio transmission coupled between the first and second shafts, and a mechanism for altering the ratio of the transmission in response to changes of a physical condition of the gas. The calibration system includes an arrangement for applying a representation of a reference state of the physical condition to the ratio altering mechanism, and indicator for indicating a fixed number of revolutions of one of the shafts, an arrangement for determining the number of revolutions of the other of the shafts corresponding to the fixed number of revolutions of the one shaft, and a calculator for determining and displaying the ratio of the other shaft revolution number to the fixed number. The calibration system also includes an adjustment mechanism for changing the zero setting and the span (or gain) of the ratio altering mechanism.

An adjustable tangent assembly for a positive displacement diaphragm gas meter is provided with a pair of concentric face gears coaxial with the axis of rotation of the crank shaft and accessible through a small plug hole in the meter cover. An adjusting tool inserted through the plug hole allows independent self locking adjustment of the timing and stroke with high resolution.

A gas meter is disclosed having a one-way index incorporated therein for causing the indicating means thereof to run only in a forward direction regardless of the actual direction of gas flow. A pivoting member is oscillated by a rotating cam coupled to the measuring means of the meter and includes pawls attached thereto for driving a ratchet wheel, coupled to the indicating means, in one direction only. By this arrangement, the oscillation of the member is independent of the direction of rotation of the cam, which rotation is indicative of the direction of gas flow.

One-way index for gas meters

Apparatus is disclosed for selectively dispensing heated water, cooled water, or water at ambient temperature. Water under pressure is supplied to a refrigerated reservoir by a water supply pipe having a solenoid operated valve therein. An ambient dispensing valve and a heated water tank having a dispensing valve are each in communication with said water supply pipe at a location between said valve and reservoir.
