Abstract: A modular manifold system for connection to a header pipe. The modular manifold system includes a central hub which has a header pipe connection, a conduit connection arrangement arranged on the central hub, and a module connection arrangement arranged on the central hub. The header pipe connection defines a flow port which permits a fluid communication between the header pipe and the central hub. The conduit connection arrangement has a conduit connected thereto and defines a flow port which permits a fluid communication between the central hub and the conduit connected to conduit connection arrangement. The module connection arrangement defines a flow port which permits a fluid communication between the central hub and a connected module.

Abstract: A method of monitoring a condition of a connection between two bodies which are connected using a connector. The connector has a sensor assembly which provides an output representing a degree of movement of one or both of the two bodies. The method includes installing the connector and the two bodies in a use position in which the connector joins the two bodies, and using the output from the sensor assembly and a numerical model to determine a force on one or both of the two bodies or of the condition of the connector. The numerical model is a record of test forces applied to a test element secured to the connector or of a test connector having a same configuration as the connector and a corresponding output from the sensor assembly of the connector or of the test connector during and/or after the application of each test force.

Abstract: The invention provides a cutting valve comprising a valve block, a gate, which is slidably within a cavity in the valve block from an open position to a closing and cutting position, an upper seat arranged in an upper part of the valve between the valve block and the gate, and a lower seat arranged in a lower part of the valve between the valve block and the gate, The valve further comprises an upper resilient member arranged between the upper seat and a lower resilient member arranged between the valve block and the lower seat. The cutting valve being distinctive in that the combination of height of upper seat, and lower seat, resilient member and any spacers on the lower side of the gate is selected so that an allowed travelling distance for the upper seat towards the valve block and an allowed travelling distance for the lower seat towards the valve block, are substantially equal.
