Sometimes these displays are enhanced by the use of directed visible laser light. Fireworks are not suitable for indoors use, because of the danger of fire, or of poisoning from toxic smokes.

It may be possible to provide elongated particles in a coiled-up of otherwise compressed form prior to use.
  • Another way to maintain particles in the air comprises use of air jets, light gases, or even hot 330 air. Static electricity might be usable.

(Of course use of an inflammable fill is inconsistent with the title of the specification). A sufficiently loud bang may follow any bursting of the envelope.
  • Preferred release means include (1) a weak envelope that bursts at a certain altitude by distension of its fill, (2) a container that bursts as a result of contact with a part of a slow- burning fuse, or (3) a container or an envelope that is burst by external actuation; perhaps a wire applied against the balloon is heated and causes the envelope to rupture - and the external actuation may be in response to a signal from a timer, an altimeter, or a remotely controlled device perhaps controlled from the ground by someone who is orchestrating the display.

Abstract

La présente invention concerne des déploiements non incendiaires comprenant principalement l'utilisation de particules relativement très lumineuses émises en averse ou en nuage à partir de moyens d'émission ou de canon qui peuvent mettre en jeu des effets acoustiques. Contrairement aux feux d'artifices, la lumière est produite sans procédé de combustion. Le matériau lumineux préféré est de l'aluminate de strontium dont on recouvre des particules de type confetti ou d'autres formes de particules conçues pour rester suspendues en l'air pendant un certain temps et qui peuvent, après excitation, continuer à briller quelques heures après être tombées sur une surface. Il est possible d'obtenir des couleurs par l'utilisation supplémentaire de colorants fluorescents ou de surfaces réfléchissantes. Des rayons lasers, des projecteurs, ou d'autres éclairages de même type peuvent permettre d'améliorer l'apparence du déploiement qui, comme les feux d'artifices, est mieux perçu dans l'obscurité. L'invention comprend les particules elles-mêmes en vrac ou sous forme de paquets, des moyens d'émission, et de systèmes de déploiement.
