The procedure and quality of the predicted transmission using this improved technique is demonstrated experimentally for an electrical motor unit with an integrated radial fan that was mounted resiliently in a vacuum cleaner casing.
Many types of plastic can be recycled and converted into new products — vacuum cleaner casings, for example.
Its selling point is that it is 70 percent "post-consumer recycled plastic," but no doubt sensing that it would be up against such scene-stealers as the dancing robo-vacs, Electrolux created a display of three vacuum cleaners with casings made from ocean debris.
But bidders stalled when four vacuum cleaners in a transparent casing appeared.
Dyson wants to use graphene in the plastic casing for its vacuum cleaners, because of its strength, and because its ability to conduct electricity reduces static, which in turn helps the machine suck in more dust.
Casting, cutting, forming, welding and mechanising are conventional production techniques for major fusion components, i.e. coil casings, coil frames, vacuum vessels and blankets.
For the cell phone, an off-the-shelf food vacuum sealer created a water-tight casing that works but also seals in the power outlet.
It included vacuum devices that attached to a centrifuge casing and sucked out virtually all the air, reducing friction around the spinning rotors.
Furthermore, the copper casing subjected to thermal treatment in the vacuum was used to isolate the rock samples and confining pressure, which can effectively transfer confining pressure and reliably resist high temperature and pressure, so as to work continuously.
The ITER magnetic diagnostics include a wide variety of sensors located on the inner and outer surfaces of the vacuum vessel, in the divertor cassettes and in the casing of the toroidal field coils.
