Abstract: A thermoforming method of fabricating a seamless, three-dimensional fixture capable of holding a liquid from a single sheet of “solid surface” material is described. The sheet is cut to desired dimensions, then heated to a desired temperature to make it malleable. The malleable material is then placed over a female or male mold, and formed to the shape of the fixture, utilizing a vacuum. The heated material is then allowed to conform to the mold shape until the desired deformity is achieved. The manufactured fixture is then allowed to cool in its restrained position, until rigid.

Abstract: A magnetic heating device comprising three electrical coils, each coil being wound around a respective magnetic yoke having a gap therein, the three yokes being arranged such that the gaps are adjacent to each other or coincident, an article to be heated being located, in use, in the gaps in the three yokes, so as to direct the magnrtic field generated in each yoke by its respective coil through the articles, each coil being connected to a respective different phase of a three phase low frequency alternating electrical supply, and one of the coils being wound in the opposite direction to the other two coil.
