Abstract: A composite storage tank comprises a composite wall enclosing a gas storage volume and defining a cylindrical portion (406) of the tank. The composite wall incorporates first) and second sets of metallic fibres each of which is susceptible to embrittlement by hydrogen and has ends extending through the exterior surface of the composite wall. By measuring the electrical resistances of the metallic fibres, a measure of the amount of hydrogen that has leaked through the composite wall over a period of time, and the present physical condition of the tank, may be determined. The approximate axial and azimuthal coordinates of a particular leakage point may also be determined.

Abstract: A method of magnetising or demagnetising an annular component for a rotary machine, a flux arrangement for performing a magnetising or demagnetising method, and a flux assembly for such a flux arrangement; wherein, the annular component includes an alternating arrangement of radial elements and angular elements for forming a Halbach array. A magnetizer is caused to induce magnetic flux in a primary set of elements of the annular component including a primary radial element and an adjacent primary angular element. A shield element shields a secondary angular element of the annular component from magnetic flux from the magnetizer.

Abstract: A procedure for repairing a polymer matrix composite component is provided. The procedure includes the steps of: providing a polymer matrix composite component having a site prepared for repair by removal of damaged or defective material; locating an uncured, polymer matrix composite repair patch at the site to re-build the component thereat; and curing the polymer matrix of the repair patch by heating the patch using eddy currents induced by one or more alternating current coils. The repair patch is without metallic additives, such that the repaired polymer matrix composite after the curing step is also without metallic additives in the vicinity of the repair patch.

Abstract: A method of manufacturing an induction motor rotor assembly, the method includes the steps of: providing a rotor; machining a plurality of re-entrant slots axially along an outer surface of the rotor; positioning a sleeve concentrically over the outer surface of the rotor; applying a friction stir welding process to the sleeve along each re-entrant slot axially along the outer surface of the rotor to cause the sleeve material to plasticise and flow into the axial re-entrant slot to form an axial re-entrant slot bar; and providing an electrical connection at each of the opposing axial ends of the rotor between respective ones of opposing ends of each of the axial re-entrant slot bars to thereby form the induction motor rotor.

Abstract: A method of manufacturing a magnetically graded material, including depositing a steel filler material to a substrate, and applying a directed energy source to first and second regions of the filler material to thereby join the filler material to form a joined material. The energy source is directed to the first region while the first region is provided with an inert shield gas such that the material of the first regions includes a magnetic phase, and the energy source is directed to the second region while the second region is provided with a nitrogen containing shield gas to thereby impart an non-magnetic phase to the joined material.

Abstract: A marine cathodic protection system configured to protect a metal structure exposed to seawater from corrosion. The system includes a first anode provided on or adjacent the protected metal structure at a first position. The first anode is exposed to seawater, is electrically insulated from the protected metal structure, and is formed of a metal having a greater negative potential than the protected metal. The system further includes a second anode provided on or adjacent the protected metal structure at a second position. The second anode is electrically connected to the first anode. The first position is preferably substantially submerged in said seawater such that the protected metal and the first anode cooperate to define a seawater battery configured to apply an electrical current to the second anode, the second anode thus being an impressed current anode.
Abstract translation: 一种船用阴极保护系统，用于保护暴露于海水中的金属结构免受腐蚀。 该系统包括在第一位置处设置在或邻近被保护金属结构的第一阳极。 第一阳极暴露于海水，与受保护的金属结构电绝缘，并由具有比受保护金属更大的负电位的金属形成。 该系统还包括在第二位置处设置在或邻近被保护金属结构的第二阳极。 第二阳极电连接到第一阳极。 优选地，第一位置基本上浸没在所述海水中，使得受保护金属和第一阳极配合以限定配置成向第二阳极施加电流的海水电池，因此第二阳极为外加电流阳极。

Abstract: An aircraft comprises a hydrogen-fuelled propulsion system, a plurality of like generally cylindrical hydrogen storage tanks and a conveying system arranged to convey hydrogen from the hydrogen storage tanks to the hydrogen-fuelled propulsion system. The aircraft further comprises a fuselage having a cargo bay (502) including one or more (510A-G) of the plurality of hydrogen storage tanks, the longitudinal axes (511A-G) of the one or more hydrogen storage tanks within the cargo bay extending parallel to the longitudinal axis (501) of the fuselage and lying in one or more planes (595, 597) extending across the width dimension of the cargo bay. The hydrogen storage tanks within the cargo bay have a common aspect ratio R in the range 4.2≤R≤25.7, allowing the volume of space with the cargo bay occupied by stored hydrogen to be maximised or approximately maximised.
