Abstract: A process and an installation for the production of a variable flow rate of at least,one principal constituent of air under pressure, wherein a constituent is withdrawn in liquid phase from an air distillation apparatus (12), this liquid is brought to a vaporization pressure, and the liquid is vaporized under this vaporization pressure by heat exchange (in 9) with a calorific fluid under high pressure. The flow rate of the constituent is adjusted by modifying the flow rate of the liquid to be vaporized and the vaporization pressure. The vaporization pressure is intermediate the withdrawal pressure and the production pressure. The gas resulting from the vaporization is compressed in a compressor (20) to the production pressure.

Abstract: Temperature of the gas stream entering the end user's internal piping system has been found to be fairly stable (at about 50 degree F.) but still variable while the temperature of the end user's internal piping system (irrespective of total length) has been found to vary as a function of the ambient temperature exterior of the end user's internal piping system. Each of such temperatures can be used in association with a differential pressure leakage detection system that uses a piezoresistive pressure sensor which measures differential pressures between the natural gas and ambient air both entering the sensor to provide a pair of output signals with the difference between these signals being related to the occurrence of small leakage of natural gas within the internal piping network of the end-user, such flow being normalized so that any such flow is due only to leakage.

Abstract: A magnetostrictive force sensor in which magnetically conductive support members are interposed between magnetically conductive end plates. The support members have magnetic properties which vary in accordance with the compressive or tensile load applied to them. The support members and end plates magnetically cooperate to create a magnetic circuit in which magnetic flux is induced by applying an alternating-current signal to a coil wound around one of the support members or by placing a permanent magnet into the magnetic circuit. When a load is applied to the magnetically conductive end plates, the magnetic properties of the support members vary to cause a change in the flux established in the magnetic circuit. The flux is detected by a second coil wound around the second support member, and the output signal detected by the detection coil is decoded to determine the load applied to the force sensor.
