Abstract: A fan-equipped apparatus comprising an elongated fan plenum for a cooling chair is disclosed. In some embodiments, an elongated fan plenum can be configured to direct airflow through a chair back and concentrate on a user's back. In some embodiments, a chair with a fan-equipped cooling apparatus and a porous chair back is provided. In some embodiments, a fan-equipped apparatus can be attached to a chair selected by the user. Thermal imaging demonstrates cooling of a user by operation of the apparatus.

Abstract: Methods for removing a melt of silicon from a crucible used in a silicon ingot growth process and associated wick assemblies are disclosed. The wick is made of porous carbon that ignites upon reaching an ignition temperature causing relatively rapid and relatively large volume take-up of silicon from the crucible.

Abstract: A chair assembly comprising a backrest, a fan assembly, and an airflow guide associated with the backrest in a manner such that airflow emitted from the fan assembly exits the chair assembly through the backrest. The assembly in various embodiments is, for example, a collapsible lawn chair, a quad chair, a bleacher chair, or an accessory for a wheelchair.

Abstract: Fan-equipped chair assemblies having a seat and a backrest. A fan assembly may be associated with a bottom of the backrest and oriented substantially upward toward a top of the backrest. An airflow guide may angle toward the top and away from the bottom of the backrest. A fan assembly may be associated with a rear of the seat and oriented substantially forward toward a front of the seat. An airflow guide may angle toward the front and away from the rear of the seat. An airflow guide may be associated with a bottom side of the seat, and a fan assembly may be attached to the airflow guide such that the airflow guide is located between the bottom side of the seat and the fan assembly. The air flow guide may at least generally taper from near the bottom side of the seat toward the fan assembly.
