  • Method of manufacturing spacers for pipe-in-pipe systems and spacer for a pipe-in-pipe structure
    Patent number: 11885457
    Abstract: A method manufacturing a spacer for a pipe-in-pipe system includes mixing aerogel particles with a polymer to form a mixture in which the particles are dispersed in the polymer. The resulting mixture is moulded and the polymer is solidified to form the spacer or a component of the spacer, in which the dispersed, particles are suspended in a matrix of the solidified polymer.
    Type: Grant

  • Additive Manufacturing for Producing Edible Compositions
    Publication number: 20160106142
    Abstract: A 3D food printing system, which can deposit macro- and micro-nutrients in an additive process to prepare a wide variety of different types of food. According to embodiments described herein, a 3D printed food system can be used to rapidly and efficiently prepare meals on demand, rather than in advance, while also allowing nutritional content, flavor, and taste to be customized for individual crew members. In some embodiments, the food can also be prepared in a largely or even completely automated fashion.
