Abstract: A costume safety mask housing chemiluminescent reagents. Upon activation, the reagents illuminate the mask or features thereon for purposes of novelty illumination and safety of the wearer. The mask may include liquid, viscous liquid, or solid chemiluminescent reagents that are held in cavities. Liquid components of the instant invention may be transported through passageways in the mask to provide a flowing appearance.

Abstract: The invention relates to a chemiluminescent light element having at least two chambers, filled with an oxalate solution and an activator solution, or variations of known chemiluminescent light materials including dyes. The oxalate solution is placed within a tight-sealed pouch made of thin aluminum foil lined on its interior side by a polymer, for instance a polyolefin, and so forms the first chamber. This latter is enclosed in a bigger tight-sealed pouch made of translucent polymer film forming the second chamber, which also contains the liquid activator. The outer pouch consists of two polymer films sealed together along their periphery and contain a ball able to pierce the inner pouch by manual action from the user.

The material includes a first layer of microspherical glass bead or prismatic light reflective plastic material having an underlying surface formed with a plurality of minute prism-like formations projecting therefrom at regular spaced intervals and an overlying substantially smooth light transmissive surface; a second layer containing a homogeneous blend of a resin containing effective amounts of a fire retardant, photoluminescent and, optionally luminescent additives; and a third layer which is a fire retardant fabric. The layers are joined at a first region such that the prism-like formations are substantially disabled or destroyed.

Abstract: This invention is directed toward a process for producing chemiluminescent light of varying coloration and to devices which utilize the process. The process incorporates multiple fluorescers, at variable concentrations, having varying degrees of stability in peroxide. At the onset of the reaction, chemiluminescent light is generated by both the peroxide stable and less stable , e.g. peroxide unstable fluorescers, resulting in a first visible color. As the peroxide attacks the unstable fluorescer, its predominant color fades, and a different color is perceived. Inclusion of this process in chemiluminescent light producing devices results in a device which changes colors during its useful life.

Abstract: The chemiluminescent light system of the present invention utilizes esters of sufficiently high purity, e.g. triethyl citrate or dimethyl phthalate as the activator solvent to provide enhancements over the prior art chemiluminescent systems. These enhancements are manifested in terms of the rate of light production, e.g. the "flatness" of the light output profile, and the total light output achieved during a device's useful life. In a preferred embodiment, the unreacted acid content of esterified solutions, useful as activators in chemiluminescent systems, should be no greater than 0.05 weight percent. The activator solutions of the instant invention also provide triethyl citrates of sufficient purity, in terms of the absence of carbon double-bond compounds, to provide enhanced light generation and increased total light output, as compared to prior art chemiluminescent systems.

Abstract: A chemiluminescent illuminated novelty device employing a a light-filtering thermoformed vessel having a form for holding chemiluminescent reagents, e.g. a round shaped chemical holding section. The lighting effects generated by reaction of the chemiluminescent reagents are enhanced by the presence of particles containing a secondary fluorescer. In one embodiment, these particles may have a particular geometrical shape, e.g. a star or heart shape, and further contain a secondary fluorescer capable of being excited by the primary chemiluminescent light source so as to emit a secondary source of light which creates a glitter effect.

Abstract: The instant invention is directed to an improved package for securing a chemiluminescent lighting device in a storage condition. In particular, the packaging consists of a heat-shrinkable opaque jacket which protects the chemiluminescent chemicals from degradation by light while simultaneously providing rigidity to the device by use of a PVC film or the like thermo-wrap-plastic capable of blocking light and adhering to the outer shape of the chemiluminescent lighting device. Due to the extremely tight fit of the material around the lighting device coupled with the presence of a score line included in the wrap material, a fracture zone is created such that any impact or flexing sufficient to cause admixture of the chemiluminescent components will, in turn, cause the wrapping material to break at the score line and be instantaneously shed.

Abstract: The instant invention is a light shield formed integral with chemiluminescent devices to effectively block ambient light thereby inhibiting photo degradation of chemical reagents when exposed to external light sources. The light shield displaces conventional foil or the like product packaging designed to protect against light yet permits instant and easy activation of chemiluminescent reagents without interfering with the chemiluminescent reaction. The integral light shields further simplify packaging and extend the product shelf life of the chemiluminescent reagents.

Abstract: An apparatus and method for indicating the onset of behavioral estrus in cattle. The apparatus is comprised of a base element with a plurality of chemical containing receptacles located on top of the base, with those receptacles being housed inside a cover which is attached to the base and enclosing the receptacles. The receptacles are pressure responsive and contain a chemiluminescent indicator. When the receptacles are discharged in response to the pressure, the chemicals are released from the receptacles and comingle and chemically react to emit light as a result of a peroxyoxalate chemiluminescent reaction. The detection patch is manufactured in a selection of colors in the management method of this invention, with each color designating a particular breeding management status for a cow. The detection apparatus is applied to the cow, which is then monitored for release of the indicator in the patch.

Abstract: This invention relates to a mounted emergency light fixture. The light fixture has a mount assembly and a front cover with a break plate which bends a light stick inserted into the fixture when the cover is pivoted from a closed position to an open position. The mount assembly has a restraining plate and a back side which maintain the light stick within the mount when the cover is pivoted to the open position. Hence, after the cover is opened the light sticks are illuminated and are held in the mount or may be removed to provide emergency lighting.

Abstract: A polygonal outer shell providing improved light transmission characteristics for chemiluminescent lighting devices. The corners created by incidence of the surfaces that comprise the shell create a fiber optic effect by concentrating the light in the corners, thus enhancing visibility of light emanating from the light stick and optimizing the amount and distribution of light radiated from the device. Furthermore, a hook-shaped tip by which the light may be suspended from means of horizontal support. In an alternate embodiment, the hook defines an opening and a quick release locking device which allows quick insertion of means of horizontal support into the eye and simultaneously prevents the support from disengaging therefrom unless the locking device is released.
