Abstract: The present disclosure provides a method for reducing the aldehyde content in an amine catalyst by treating the amine catalyst with a treating agent selected from a cyclic urea substituted with at least one isocyanate reactive group, a free radical scavenger and a mixture thereof. The treated amine catalyst may then be used in the production of polyurethane materials which exhibit reduced aldehyde emissions.

Abstract: The present disclosure in an embodiment provides a portable exercise apparatus. The portable exercise apparatus comprises a bar having a first end and a second end along a longitudinal axis. Further, the portable exercise apparatus comprises two frame members. Each frame member comprises a groove on top, coupled to the bar such that the bar rests on the two frame members along the longitudinal axis of the bar and on the grooves of the two frame members. The two frame members are opposite to each other at each end of the bar. Further, each frame member is coupled to a pair of wheels at a bottom portion of each frame member. Further, the bar has a grip portion, between the first end and the second end, to support stresses perpendicular to the longitudinal axis of the bar.

Abstract: A method and apparatus for the removal of foam produced in the primary fermentation step of home brewmaking comprises primarily a kraeusen trap including a platform of a diameter slightly less than the inside diameter of a primary fermenter and one or more chimneys to permit the flow of foam from below the platform to the top surface of the platform. The device may also include means for maintaining a space between the perimeter of the platform and the inside surface of the primary fermenter. This space permits foam to flow around the platform to the top surface of the platform, and for beer brought with the foam to settle back into the batch. Each of the one or more chimneys may also include one or more drain holes for the flow of beer into the batch. The space between the platform and the inside diameter of the primary fermented is preferably maintained by a plurality of spacers, which preferably clip onto the perimeter of the platform.
