The improved density information obtained for both embodiments is unaffected by temperature changes and is used to validate the flow calibration factor. The flow calibration factor compensation for pressure changes and changes in material composition is obtained in a similar manner.

Abstract: A jack assembly, for use in a materials testing system, utilizes both a cam and a resilient push block. The cam, having an progressive eccentric, is situated between the push block and a jaw housing and located partially within a corresponding shallow channel in each such that both channels effectively straddle the cam. The channels accommodate axial rotation of the cam. The push block is formed of a material with an appropriate modulus of elasticity such that bending moments, particularly at ends of the push block and resulting from axial rotation of the eccentric to its top dead-center position, cause the channel in the push block to elastically deform and increasingly and sufficiently deflect against and around the eccentric, thus increasingly pinching the eccentric and securely locking the cam, push block and specimen grip in their proper positions.

Abstract: In order to extract a part of a three-phase flow from a pipe line, a pair of communication pipes, which are connected to upstream and downstream sides of an orifice provided in the pipe line, and a gas-liquid extraction tank are used. Flowing of a slag flow or the like into the pipe line causes a periodical change in a pressure difference between input and output sides of the orifice. This causes extraction of gas-liquid and discharge mainly of gas to be simultaneously effected in the pair of communication pipes and the gas-liquid extraction tank. Within the gas-liquid extraction tank, the gas-liquid is forcibly shaken horizontally, vertically, etc. for agitating, whereby gas-liquid of high liquid-phase rate remains. Then, the gas is removed from this gas-liquid of high liquid-phase rate to thereby extract mixture liquid, which is accumulated in a liquid storage tank. The mixture liquid flows from the liquid storage tank in an amount required at a Coriolis meter.
