The present invention relates to a system and methodology to facilitate development, debug, and deployment of a notification platform application. The machine comprises a refrigerated mixer, a plurality of hoses connecting the refrigerated mixer to a filling head, a bath having a housing and a tank for liquid nitrogen, a bath belt rotatably engaged to the housing, a cluster cylinder rotatably engaged to the housing, and a delivery belt. In accordance with the present invention, a length of the cords forming the reinforcing layer in the tire circumferential direction can be made short, whereby a size of tread pieces formed at a time when the tire is damaged can be made small and damage caused to an airplane can be reduced. Further, the symbol combining device can be easily adaptable to change of the number of channels for various services. Methods for forming thermally treated expanded perlite as well as methods for forming thermally treated perlite coated or impregnated with an active material are also disclosed. The apparatus accomplishes redirecting, splitting and transforming a Gaussian profile input optical signal into a desired plurality of homogenized, top-hat profile output signals in a compact configuration that is highly optically efficient.
