Techniques for coating pipes
10160147 · 2018-12-25 · ·

A method and apparatus are for coating a field joint of a pipeline. The method includes positioning a mold tool around the field joint to define a mold cavity, positioning an insert to lie within the mold cavity, and injecting plastics material into the mold cavity to embed the insert in the plastics material. The apparatus has a mold tool positionable around the field joint to define a mold cavity, and an insert positionable within the mold cavity to be embedded in plastics material injected into the mold cavity. Use of an insert in this way reduces the volume of the molten thermoplastics material required to coat the field joint, thereby increasing the interface area of the melt relative to its volume, to the benefit of cooling time.

Pole-piece bonding

We describe a method of manufacturing a housing for the stator of an axial flux permanent magnet machine, in particular a Yokeless and Segmented Armature motor, the machine having a stator comprising a set of coils wound on respective stator bars and disposed circumferentially at intervals about an axis of the machine, and a rotor bearing a set of permanent magnets and mounted for rotation about said axis, and wherein said rotor and stator are spaced apart along said axis to define a gap therebetween in which magnetic flux in the machine is generally in an axial direction. The method comprises: fabricating a radial wall for said stator housing to be located in said gap between said rotor and said stator by: providing a membrane of fibre-reinforced polymer material; pressing a set of said stator bars into said membrane of fibre-reinforced polymer whilst said polymer is mouldable, wherein said reinforcement inhibits said stator bars from pushing through said membrane; solidifying said polymer to hold said set of stator bars in their respective positions; and manufacturing said housing using said radial wall.

Method and device for preheating a mold for injection molding
09862132 · 2018-01-09 · ·

A method and device for pre-heating a first molding surface of a mold with an open position and a closed position defining a closed cavity between the first pre-heated molding surface and a second molding surface. A core is inductively heated outside the mold by placing the core inside a coil having an AC current passing there through. The core is inserted between the molding surfaces of the mold in the open position. The first molding surface is preheated by transferring the heat between the core and the first molding surface. The core is then removed and the mold is closed.
