    摘要: The invention relates to piping comprising a portion wherein the centreline of the portion follows a substantially helical path, wherein the amplitude of the helix is less than or equal to one half of the internal diameter of the piping. When fluid flows in such piping, it is made to swirl. This provides a number of advantages, such as improved in-plane mixing of the fluid, enhanced uniformity of residence time, and so on. The invention also extends to various methods of making such piping.

    摘要: A process for separating suspended material from a fluid comprising flowing the fluid through a porous matrix. The porous matrix is elastically deformable and restrained at its outlet end. The flow rate is sufficiently large so as to produce non uniform deformation of the porous matrix and thereby a gradient of porosity in the direction of fluid flow. At least a part of the suspended material is separated by retention within the porous matrix. The porous matrix/fluid system has a self cleaning capability.

    摘要: A method of determining the instantaneous arterial blood pressure of a subject which is a living being without utilizing entry of a needle or the like along an artery is capable of a high degree of accuracy and comprises the steps of applying a pressurizable device in the region of an artery and controllably pressurizing that device with fluid to an extent sufficient to eliminate arterial wall movement without collapse of the artery, the fluid pressure in the pressurizable device being monitored and providing a measure of the instantaneous arterial blood pressure of the subject. A preferred form of pressurizable device is an annular ring or cuff comprising a rigid body of annular shape over the inner surface of which is stretched a latex membrane which is pressurizable with distilled water.
