Abstract: The current embodiments provide an assembly for cooling a printed circuit board with at least one electronic component disposed on a first surface of the printed circuit board. The assembly may have a housing with first and second elastic elements and a cooling element configured to cool the at least one electronic component. The printed circuit board may be held between the first and second elastic elements in the housing. The assembly may further have at least one cooling surface region protruding from the cooling element and facing toward a second surface facing opposite the first surface of the printed circuit board in a region opposite of the electronic component.

Abstract: The invention relates to use of surfactant mixtures in drilling fluids, the mixtures are produced by reacting an aqueous solution of at least one alkyl oligoglycoside and/or alkenyl oligoglycoside with an omega haloacid, or its salts or esters in the presence of an alkali. The mixtures are suitable for use as emulsifiers for invert drilling-fluid systems and improve the filtration characteristics of the systems.

Abstract: An external utilities manager is designed for post and beam furniture systems of the type having overhead beams supported on vertical posts. The posts include outwardly protruding flanges which extend along the length of the posts. The external utilities manager includes a vertical raceway having a hollow interior configured to route utilities therealong, and an enclosed exterior disposed between the flanges of an associated post, and extending therealong to an open upper end. A horizontal raceway is positioned adjacent to and extends along the side face of an associated beam, and includes an interior configured to route utilities therealong. One end of the horizontal raceway is positioned adjacent to and communicates with the upper end of the vertical raceway to route utilities throughout the furniture system.
