Abstract: An apparatus for compacting a powder includes a feed section (20), a compaction section (21), a discharge section (22), and a conveyor belt (103) extending through the feed, compaction, and discharge sections to convey powder through those sections. The feed section receives an incoming powder onto the conveyor belt. The compaction section compresses the incoming powder on the conveyor belt between two plates (8, 9) to provide a compacted powder. The top plate (8) may be pressed downward toward the bottom plate (9), the bottom plate may be pressed upward toward the top plate, or both. The discharge section receives the compacted powder from the compaction section on the conveyor belt. End plates (16) and side plates (11) confine the incoming powder during compaction.

Abstract: Fluffy powders, such as calcined kaolin clays or air floated clays, can be compacted using a process which comprises applying increasing amounts of pressure to a powder moving through a confinement area. The compacted product has an improved bulk density and improved wet out and slurry incorporation times as compared to the non-compacted starting material feed.

Abstract: Calcined kaolin clay having a high bulk density, improved wet out and slurry incorporation times is produced by using pressure to compact the clay. Other properties of the compacted clay are improved or equivalent to the non-compacted starting calcined clay material.

Abstract: A fireplace has an imperforate dished fire-pan, the sloping sides of which support the fire, which radiates through an opening in the wall of a conical enclosure superposed on the fire-pan. An outer frustoconical casing in most cases surrounds the enclosure, with an opening in register with the opening in the disclosure, and defines an air circulation space through which air circulates upwardly from beneath the fire-pan up into the room. A duct from the exterior of the room to be heated may extend into the space beneath the fire-pan, which space may also contain a water pan to humidify the circulating air. A fire control member is rotatable between the enclosure and the casing so as optionally to obturate the openings therein with either a mesh fire screen or a plate closing off the openings. The fireplace aims to provide complete and controllable combustion of wood fuel, and efficient space heating and, optionally, ventilation of a room in which it is situated.
