Abstract: A fluidized bed coffee roaster controls air flow and/or temperature to maintain a desired time-temperature roast profile. The roaster may also provide a two stage quenching cycle for rapidly cooling roasted coffee beans to ambient temperature. In a first stage of the quenching cycle unheated air is passed through the roasted beans while they are still in the roasting chamber of the fluidized bed roaster. In a second stage of the quenching cycle which is carried out outside of the roasting chamber, in a fluidized bed quenching station, unheated air is flowed through, and fluidizes, the roasted coffee beans cooling them to ambient temperature.

Abstract: A self-cleaning system for delivering sanitized water to a workstation has a boiler which produces heat-sanitized water and steam. A diverter valve permits a fluid delivery line of the system to convey either sanitized water or steam to a workstation. The steam serves to sanitize the delivery line and workstation and removes biofilms therefrom.

Abstract: A body has a through bore with first and second ends and an intermediate disposed transverse bore extending through a side wall in fluid flow communication with the through bore. A flow control member with a first transverse bore is movably mounted on the body. The flow control member is movable from a first position in which the first transverse bore is aligned with the transverse bore in the body to form a fluid flow path therethrough to a container attached to one end of the body, and a second position in which the first transverse bore is offset from the transverse bore in the body to block fluid flow through the body. A septum, mounted in the second end of the through bore of the body, is piercable by a syringe to withdraw or inject quantities of gas from or into the container attached to the body.

Abstract: A gas emission sample container includes first and second flexible sheets sealed at their peripheral edges to form a closed interior cavity. A plurality of spaced, discrete projections are formed in at least one of the sheets and extend inward to the interior cavity toward the opposed sheet. Gas flow paths are formed between adjacent projections on the one sheet within the interior cavity for complete inflation and evacuation of the container. A fitting is mounted in the interior cavity in the container and includes a body with top and bottom surfaces curving smoothly to a peripheral edge. A first bore extends centrally through the top surface into the body of the fitting. A plurality of second bores are formed in the body and extend tangentially from the first bore to the peripheral edge of the body to dispose of the first bore in fluid communication with the interior of the container.

Abstract: A two-part hanger includes a hook portion having first and second legs engageable by a second lower portion formed of first and second inclined shoulder rails integrally joined by a horizontal rail. A friction producing surface is applied to at least portions of the first and second shoulder rails and the horizontal rail. The method of manufacturing the two-part hanger includes the steps of injection molding a hook portion having first and second diverging legs and extruding a hollow tubular member. The hollow tubular member is bent at opposed ends to form first and second inclined shoulder rails joined by an integral horizontal rail. Flocking particles are sprayed over or, alternately, a plurality of strands are wound into an interknit braid over an adhesive coating applied to the elongated tubular member prior to the bending of the ends of the tubular member to form the frist and second inclined shoulder rails.

Abstract: A separable, multipart hanger includes a hook portion having first and second legs. First and second shoulder rails are releasably mounted in the ends of the first and second legs and inclined outwardly from the hook portion. First and second shoulder caps are releasably joined to the opposite ends of the first and second shoulder rails. A horizontal rail is releasably attached to the opposite ends of the first and second shoulder caps. The exterior surface of the shoulder caps are smoothly curved. A friction producing surface is adhesively attached to the exposed portions of at least certain of the first and second shoulder rails and the horizontal rail.
