Abstract: The apparatus or “chiller” uses an upward stream of ambient air drawn through the upright housing to cool crumb rubber particles that are deposited into and fall through the housing. The chiller includes an upright chiller housing and an array of internal baffles disposed within the lower section of the housing. Crumb rubber deposited into the chiller housing falls through the upward air flow within the chiller housing and cascades around and through the baffle array before exiting the chiller. The baffle array inside the lower section of the chiller housing slows the fall of the crumb rubber, thereby increasing the dwell time through the chiller to provide enhanced cooling. The baffle array also creates a more turbulent air flow through which the crumb rubber falls. The rising turbulent air mass enhances the transfer of thermal energy from the falling crumb rubber.

Abstract: An assembly for a console of a vehicle including a main body, a first hook connected to the main body wherein the hook is positioned adjacent and spaced apart from a second hook. A duct member having an aperture connects to the first hook and the second hook. During installation of the duct portion the aperture is first angled and positioned over a first hook then rotated downwards over the second hook wherein the second hook includes a ramped portion. The duct portion is snapped into place and is secured tightly over both the first hook and the second hook. During installation and rotation of the duct portion over the first hook and the second hook, the first hook and the second hook resiliently bend towards each other in compression and are relaxed once the aperture is fully over the first hook and the second hook.

Abstract: An appropriately treated flow of air is supplied to a room in an automatically executed pulsed operation, in which the air flow is alternately switched on and switched off. The air flow is switched off independently of the room usage state if the regulated room comfort variables lie within a respectively assigned comfort band. If at least one of the regulated room comfort variables lies outside the comfort band assigned to it, the flow of air minimized in respect of its volume is supplied to the room. This means that ventilators used for the exchange of air will be operated at the lowest possible speed, optimized in respect of time and thereby with high energy efficiency.
