  • Publication number: 20240003133
    Abstract: The present invention relates to a lightweight composite architectural panel assembly, comprising: a) at least a first and a second end joist spaced parallelly along a perimeter of the assembly, each having a length; b) at least one web plate spaced parallelly between the end joists; an upper surface arranged in parallel to a lower surface; and attached to the at least first and a second end joist and the web plate, forming one or more channels disposed vertically between the upper and lower surfaces and longitudinally extending along the upper and lower surfaces, thereby forming an open-ended boxlike body; and c) a structural vertically load-bearing sheathing layer enveloping and adherent to the outer surface of the open-ended boxlike body, wherein the sheathing layer comprises a composite skin comprising a fibre mesh and a crosslinked polymeric resin system.

  • Patent number: 6501223
    Abstract: The present invention relates to a color display device comprising a color display tube (1) with a front portion having a truncated cone (3), an element (5) for generating a plurality of electron beams, a shielding (9) of ferromagnetic material extending substantially parallel to the truncated cone (3), and a demagnetizing device having at least two demagnetizing coils (11,12) extending along the outer circumference of the cone (3). The demagnetizing device is arranged to energize the coils (11,12) simultaneously and with a phase difference, resulting in the generation of a rotating magnetic field. As the magnetic field rotates, it can be arranged to substantially coincide with the shape of the shielding (9), resulting in a magnetic field that is parallel to the shielding (9) over a larger part of the shielding surface. This improves the demagnetizing procedure, leading to a better landing performance of the electron beams.
