Title: Method of moulding
Inventor: ALAN ROGER HARPER
IPC: B29C70/54
Filed: 2017-05-31
Abstract: A method of composite moulding including placing reinforcement fibre 5 between a mould surface 6 and a flexible diaphragm 3 and causing upward movement of the diaphragm to produce a resin flow channel 14 along which resin is caused to flow. A reusable element (20, fig 2-4) , preferably in the form of disc with a chamfered edge, formed with a plurality of resin flow channels (27, fig 2-4) is positioned beneath the flexible diaphragm to direct resin under the membrane. The reusable disc 20 is preferably placed on top of fibre mats in alignment with the resin entry port. Preferably, in use a vacuum pressure is supplied to pipes 9 and 10; as a result, the pressure P2 provided by incoming resin in inlet pipe 11 results in an upward deflection of diaphragm 3 into a free space within chamber 2 resulting in the formation of flow channel 14.

Title: A power electronics module and a method of detecting a fault in a power electronics module
Inventor: CHANDANA JAYAMPATHI GAJANAYAKE
IPC: H03K17/08
Filed: 2017-07-21
Abstract: A power electronics module (e.g. inverter) includes at least one solid state switching device M1 (e.g. MOSFET, IGBT), a gate driver, a controller and a fault detector. The gate driver connects to, and provides a drive input to, a gate terminal of the switching device to activate the switching device. The controller provides a gate signal to the gate driver. The fault detector includes a capacitor (e.g. external Miller capacitor, CM) connected to a collector terminal of the switching device and a comparator connected to the capacitor. The comparator compares a voltage received from the capacitor against a threshold voltage. If the voltage exceeds the threshold, a control signal indicates a short circuit fault. The control signal may activate a fault protection circuit which reduces the current and/or voltage received by the switching device. The capacitor may be further connected to the controller via an isolation circuit. The controller may assess the severity of the fault, based on the signal received from the capacitor via the isolation circuit and, if the fault exceeds a shut-down threshold, the gate driver and, thus, the switching device is disabled.

Abstract: A casing annulus washing tool 10 comprises a housing with injection apertures 16 and an uphole pressure reduction apparatus 34. The injection apertures 16 can be in an injection region 39 defined by upper 18 and lower 20 seals. The pressure reduction apparatus 34 can have helical vanes (36, fig 3a) and fluid ports 32, to increase the speed and turbulence of the well fluid, locally decreasing pressure in the wellbore. In use, perforations 38 are made or may be present in the region to be cleaned. The tool 34 is positioned at lower perforations 38a and seals 18, 20 can form the injection region 39 so washing fluid flushes into the annulus 46. The pressure reduction apparatus 34 creates an area of lower pressure uphole of the injection zone to suck A the washing fluid back into the cased wellbore in the area of upper perforations 38b where it then returns to the surface B. The tool 34 can be moved downhole in incremental step-wise motion or moved continuously to wash the casing annulus further downhole. A pressure bypass apparatus is described (figs 7a-7c) to mitigate kicks when the tool is plugged in place.
