Abstract: A device and system for measuring a temperature of a liquid food product includes a housing (3) having an inlet (5) and an outlet (6) for allowing passage of liquid food product through the housing (3), a temperature probe (2) located within the housing (3) for providing a signal representative of a temperature of liquid food product passing through the housing (3), and a scraping sleeve (7) that is concentrically arranged over the temperature probe (2) and axially moveable along the temperature probe (2) to scrape and remove deposits from the temperature probe (2) that have been formed by accumulation of liquid food product on an outer surface (8) of the temperature probe (2).

Abstract: A kitchen hood assembly includes a combination hood cleaning and fire suppression system. The hood assembly includes a hood structure and a riser connected thereto. An exhaust blower forces an exhaust stream of air into the hood and through the riser. A combination hood cleaning and fire suppression system is incorporated into the hood structure. The combination hood cleaning and fire suppression system includes an elongated spray bar that is connected to a water source and includes a surfactant injector that injects a surfactant into the water being directed to the spray bar. In one mode of operation, the spray bar is effective to clean the hood assembly. In another mode of operation, when a fire is sensed in or in the vicinity of the hood, the same spray bar is utilized to inject an aqueous liquid into the hood to suppress the fire.

Abstract: Acoustically absorptive carpeting includes a primary layer of fibrous material with yarn tufts extending outwardly therefrom and a secondary layer of thermoplastic material that forms a carpet backing. The carpet backing is rendered porous. A substrate of porous material is attached to the carpet backing. The substrate includes a layer of fine fibrous material attached to a layer of coarse fibrous material. The layers of fine and coarse fibrous material each have respective different acoustic impedances. The layer of coarse fibrous material has fibers in an open, loose configuration. The carpet backing is bonded to the layer of coarse fibrous material with a thermoplastic adhesive material such that the thermoplastic adhesive material encapsulates individual fibers of the layer of coarse fibrous material without extending therebetween.

Abstract: Apparatus and methods are provided forming a sound attenuating laminate that has a decoupler fiber layer and a mass layer in opposing relationship with each other. The decoupler fiber layer and mass layer of the laminate are heated to the selected temperature in substantially the same amount of time via a hot air source and a heated platen, respectively. The heated laminate is conveyed to a mold and formed into a predetermined three-dimensional configuration via the mold.

Abstract: Sound attenuating laminates, and methods of making the same, are provided. Heat is applied to a surface of a non-woven, fibrous layer of material to form a stratum of melted fibers having a density greater than that of the remainder of the fibrous layer. The density of the melted fibers is effective in attenuating noise traversing the fibrous layer of material. Upholstery material, such as carpeting, is attached to the surface of the heated fibrous layer. The fibrous layer and upholstery material are then subjected to compressive molding pressure to obtain a desired shape. The compressive molding pressure may further tune the sound attenuating properties of the fibrous layer by selectively changing the densities of portions of the fibrous layer.
