The invention comprises a novel pet ball with an anchored squeaker which will not break or otherwise be inoperable by a firm bite of a pet. A malleable inner and outer shell construction makes the ball simple yet less prone to damage as it allows the squeaker insert to move to a degree in response to pressure of a bite. The squeaker cannot be dislodged from int's insert. The outer shell of a wooly fabric covers the exit portion of the squeaker yet allows sound and air to travel though the ball.

Dual-tone horn assemblies and methods of use are disclosed herein. An example dual scroll assembly includes a nozzle having a first portion of the nozzle has a first diameter and a second portion of the nozzle has a second diameter that has a size that is different from the first diameter, a first spiraled channel that receives air from the first portion of the nozzle. The air traveling through the first spiraled channel produces a first tone at a first frequency. A divider plate is disposed between the first spiraled channel and a second spiraled channel. The second spiraled channel receives the air from the second portion of the nozzle. The air traveling through the second spiraled channel produces a second tone at a second frequency. The first tone and the second tone when produced simultaneously create a dyad.

The present disclosure is directed to a game call that can be used to attract, mimic, or communicate with game animals. The game call comprises a plurality of components including an insulating component comprising heat insulating properties. The insulating component is disposed in a location on the game call that provides insulation, in particular, to critical components located in interior portions of the game call. The insulating part may provide insulation to interior parts of the game call including reeds and other critical interior parts of the game call.

The invention is a series of three plush squeaking toys that are obscured within a decorative pop top can so that the user cannot see which character is inside the can, and provides a surprise toy which encourages the consumer to collect the set.

A duck call device includes a tone board having a tone surface and a tone board port defined, relative to airflow, behind the tone surface. The tone board port is divided into multiple channels to form a multi-channel port. A reed is located on the tone surface and is configured to vibrate there against. The multi-channel port may be created by a longitudinal central rib dividing a portion of the tone board port, wherein the longitudinal central rib contacts the reed while air is passing through the duck call device. The tone surface may surround a portion of the tone board port with recessed edges, and the central rib may have recessed edges.

The present invention relates to a process for cooling a metal component, the process comprising the step of cooling said component in a confined space, said cooling involving cooling by means of a gas, the gas being cooled by heat exchange with a cooling surface of a heat sink inside said confined space, wherein a low frequency sound wave is provided into said confined space in order to improve heat exchange both between the gas and a cooling surface of the at least one heat sink, and between the gas and the metal component, characterised in that the cooling gas comprises at least one protective inert gas. The invention further relates to an apparatus for performing the process.

A pedestrian warning device, comprising a warning device body having a cavity and an open end portion, and a sound-generating device mounted inside the cavity, wherein the pedestrian warning device further comprises a grille cover arranged on the end portion of the warning device body; the grille cover comprises at least two grille layers spaced at intervals from the inside to the outside, each of the grille layers comprising a plurality of crossbeams, the crossbeams being arranged at intervals so as to form gaps to enable gas to flow between adjacent crossbeams, and wherein a width of the gaps is not greater than a width of the crossbeams, and the crossbeams of adjacent grille layers are interleaved with each other. The grille cover can protect internal component of the pedestrian warning device and will not affect the performance of the pedestrian warning device.
