Date Jul. 3, 1986.A method of measuring the volume (V) of a gas in a container (20) comprises varying the container volume according to a sine wave between a minimum and a maximum value, the variation being made at a constant frequency but at varying amplitude, to obtain a predetermined pressure difference ( DELTA p), and the volume difference ( DELTA V) corresponding to said predetermined pressure difference ( DELTA p) being determined by detecting the points of time when at least two points on the sine wave are attained which correspond to two predetermined values of the container volume. By measuring the time between the two points on the sine wave, the sine wave peak values for the volume difference ( DELTA V) corresponding to said predetermined pressure difference ( DELTA p) may be calculated and, thus, the said volume difference ( DELTA V). By means of the formula V= DELTA Vxp0x eta / DELTA p, wherein p0=the static pressure and  eta =Cp/Cv wherein Cp an Cv are the specific heat capacity at, respectively, constant pressure and constant volume for the gas within the container, the gas volume (V) in the container may then be determined.

Abstract: A clamping device of a static umbrella (e.g. the frame of a garden or beach umbrella) has a segment which is flexibly connected to a bush which surrounds an umbrella stick. A handle rotatably mounted in a boss attached to the bush is able to overcome the natural springiness of the segment to move it towards the umbrella stick so that a clamping cheek of the segment holds the umbrella stick in position relative to a base tube. With this construction, the device need have no longitudinal split, which would expose the mechanism to the effects of the weather, and the mechanism is enclosed, thereby preventing the umbrella stick or users from being hurt on the sharp corners and edges of the mechanism.
