Abstract: A refractory vessel that can be used as a gasifier for black liquor includes a generally cylindrical metal shell having a dome. A refractory shell has a cylindrical portion spaced inwardly from the metal shell and a dome portion that is spaced inwardly from the metal dome. The refractory shell is sized to provide an expansion gap between the liner and the metal shell. A selectively crushable liner is positioned in the gap. The liner has a predetermined yield stress that will provide controlled resistance to expansion of the refractory shell.

Abstract: This invention relates to the measurement of various haemostatis, clotting, and the like properties of blood.

Abstract: This invention relates to the measurement of various haemostatis, clotting, and the like properties of blood.

Abstract: An apparatus for measuring physical properties of blood is disclosed. Two reservoirs are provided connected to a receptacle means by at least two elongated tubes. A punching station located along the two tubes permits the simultaneous punching of holes to simulate bleeding in the tubes. The bleeding of the tubes is monitored to indicate the haemostasis properties of blood flowing through the elongated tubes. Monitoring is effected by measuring the downstream pressure of a punched tube. Alternate embodiments include the addition of third channel having a collagen material within the channel. Platelet aggregation on the collagen material is observed as a measure of haemostasis properties of the blood.

Abstract: Apparatus and method for modeling of thrombogenesis using haemostasis measuring devices. A sleeve member is provided on a blood-carrying tube to simulate an environment of a human artery. When punctured with a small needle, bleeding is simulated, permitting blood to be trapped between the sleeve and blood-carrying tube. The trapped blood communicates with the blood flowing in the tube, resulting in thrombus formation.
