Abstract: An apparatus comprises an enclosure having exterior walls defining an interior space; a top (10) having an interior surface (12) and a plurality of coupling clips (30) extending from the interior surface; and a base (5) having an inner surface (14). The base has a plurality of clip receiving members extending from the inner surface and reversibly engaging the coupling clips to secure the top to the base. The base further includes at least one aperture (7) adapted to permit a release fixture (50) having a plurality of decoupling members (40) extending from a plate (51) to simultaneously disengage the clip receiving members.

Abstract: The disclosed embodiments relate to a display device with a speaker grill. More specifically, there is provided a display device (10) comprising a display screen (16), a frame (14) disposed around the display screen (16), and a speaker grill (18) coupled to the frame (14) and the display screen (16), wherein the display screen (16) is lodged between a support bracket (22) of the speaker grill (18) and an edge portion (23) of the speaker grill (18).

Abstract: A heating plant has a fuel container with an evaporation space or chamber from which evaporated fuel is passed to a combustion chamber. Combustion gases pass from the combustion chamber through a heating tube, for discharge, while part of said gases is fed back to the evaporation chamber. The feedback path has variable insulation or flow control to control the feedback gas temperature thus to maintain constant the amount of heat fed back, irrespective of the combustion chamber heat output. The connections of evaporation chamber to combustion chamber and evaporation chamber to heating tube, by way of the gas feedback tube, are rendered more secure by mechanical support means such as bracing struts, to resist operating and transportation stresses.
