Abstract: A method and apparatus for making a tire with a built in sealant is provided. The method includes the steps of mounting an inner liner onto a tire building drum, extruding a sealant composition into strips having tapered sidewalls, cutting the strip to a desired length, mounting the sealant over the inner liner, and layering one or more tire components over the sealant.

Abstract: Loudspeaker equipment embodying a speaker, an enclosure for the speaker which is substantially closed except for the speaker opening and which is formed of walls which are thin and therefore capable of excitation and consequent sound generating vibrations under the influence of the speaker, the speaker equipment further including a reflector surrounding the speaker enclosure and having an open front through which the speaker is exposed, the walls of the reflector being spaced from the walls of the speaker enclosure to provide a passage through which sound generated by the walls of the speaker enclosure is reflected forwardly. The side walls of the reflector include a plurality of wall elements with adjacent edges spaced from each other and having a thickness dimension sufficiently small to provide for excitation and sound generation under the influence of the speaker enclosure within the reflector.

Abstract: Loudspeaker equipment is disclosed of a type comprising a speaker and a speaker enclosure, the enclosure having intercommunicating front and rear compartments, the front compartment being of larger volume than the rear compartment, and the compartments being defined by walls formed of sheet material and being substantially imperforate, except for a speaker opening in one wall thereof.
