Abstract: The present disclosure provides a system for regulating a temperature of a portion of an article of furniture, and methods of use thereof. The system may comprise at least one sensor configured to detect a biological signal of a user of the article of furniture. The system may comprise a temperature control device configured to change the temperature of the portion of the article of furniture. The system may comprise a processor configured to (i) designate, while the user is asleep on the article of furniture, a time for the article of furniture to wake up the user based on the biological signal of the user that is detected by the at least one sensor while the user is using the article of furniture, and (ii) change the temperature of the portion of the article of furniture by the temperature control device prior to the time.

Abstract: Disclosed herein is a method for recycling synthetic turf that includes agglomerating a plurality of synthetic turf fragments and extruding the agglomerated material. The method produces a recycled material suitable for use as infill in a synthetic turf. Accordingly, an infill for synthetic turf and a synthetic turf including that infill are also disclosed herein.

Abstract: A process for repairing a compressor rear frame of a gas turbine engine. The process entails removing a seal flange from the inner casing wall of the frame to define an annular face on the casing wall, and fabricating a replacement flange to have an annular face with a radial width greater than the radial width of the annular face of the casing wall. The faces of the flange and wall are mated to form a joint, a penetration-enhancing flux is deposited adjacent the joint, and a single-pass gas tungsten arc welding operation is performed to form a root weldment that extends completely through the joint. The flux is then removed and a gas tungsten arc welding operation is performed to deposit a filler on the root weldment and form a second weldment that completely overlays but does not penetrate through the root weldment.

Abstract: A heat treatment process that will restore the mechanical properties of an aircraft engine article that includes a cast nickel-based superalloy portion welded to a wrought portion. The heat treatment process includes placing an article that includes the nickel-based superalloy cast portion into a heat treatment chamber, evacuating the chamber to a suitable atmosphere, heating the chamber in a manner that minimizes distortion of the cast portion to a temperature in the range of 1950° F. to 2050° F., holding the temperature in that range for a period of time sufficient to solution all the delta phase precipitates, and then cooling the article to room temperature in a manner that minimizes distortion of the article. After solution heat treatment, the wrought portion of the engine part can be removed and replaced and the engine article can be reprocessed.
