The device comprises at least one enclosure in which the electrochemical component of the battery is housed, at least one magnetocaloric heat pump associated with the enclosure, at least one heat transfer fluid circulating circuit coupled between the battery and the heat pump and at least one heat exchanging component that is open to the exterior environment and connected to the heat transfer fluid circulating circuit to exchange calories with the exterior environment.

Abstract: The present invention provides for an improved device for molding keyhole sipes larger in size, i.e. sipes having a wider passage, than currently being formed in treads that will avoid damaging the tread during formation and removal thereof from a mold. The device includes an elongated deformable body member having a blade extending in a direction away therefrom and substantially along the length thereof. The body member also includes a stiffening member securely fixed in position therein that extends substantially the length thereof. The stiffening member provides a desired rigidity to the deformable body member, thereby limiting flexion along its length under the stress of a rubber formulation when the mold is closed during the molding process. Also, the deformable body member provides low stress on the tread when a slit of the keyhole sipe is pulled around the body member during removal of the tread from a mold.

Abstract: A pneumatic tire with an improved balance between noise reduction and hydroplaning resistance as the tread wears. The tread of the pneumatic tire includes skewed tread blocks having walls that, as the tread wears, change the character of the lateral and circumferential channels in the tire footprint to better optimize noise reduction and hydroplaning resistance.

Abstract: A pool light mounting system includes a circular band formed of resilient material. The band has first and second adjusting brackets at either end. The brackets have substantially planar surfaces located orthogonally to the band. The planar surfaces have first and second apertures penetrating the surfaces. The apertures are sized to fit slidably over a threaded stud. First and second nuts are threaded to fit the threaded stud and located on the stud located within the first and second apertures. First and second mounting brackets are attached to the band having third and fourth planar surfaces spaced forwardly from and parallel to a front edge of the band. The third surface has a receiving notch for a mounting hook. The fourth surface is located opposite the first mounting bracket along the band and has a threaded hole sized and shaped to accept a threaded mounting screw for a lighting fixture.
