Title: A piping and pumping arrangement for apparatuses employing two-phase heat transfer
Inventor: LAGANA ANTONINO
IPC: F28D15/02
Filed: 2009-09-15
Abstract: A two-phase thermosyphon is an apparatus that can be used in heat recovery applications. For example, it can be used to transfer heat from warm air to cold air. In order to transfer heat, a two-phase thermosyphon uses a fluid that evaporates in one of its components and condenses in another. The component in which the fluid condenses is called the "condenser" and the component in which the fluid evaporates is called the "evaporator". The condenser releases heat whereas the evaporator absorbs it.     In a two-phase thermosyphon, the condenser must be at an elevation that is higher than that of the evaporator. This is so because the fluid that condenses must flow into the evaporator under the effects of gravity alone. This constraint prevents the use of a two-phase thermosyphon in heat recovery applications where it is not possible to place the condenser above the evaporator.     The present invention allows the condenser to be placed at any elevation with respect to the elevation of the evaporator. It permits the condenser and evaporator to transfer heat the same way they would in a two-phase thermosyphon. The present invention consists of a pump, reservoir and a series of pipes arranged in a special way to achieve that purpose.

Abstract: Techniques for mitigating interference on control channels in a wireless communication network are described. In an aspect, high interference on radio resources used for a control channel may be mitigated by sending a request to reduce interference to one or more interfering stations. Each interfering station may reduce its transmit power on the radio resources, which may then allow the control channel to observe less interference. In one design, a user equipment (UE) may detect high interference on radio resources used for a control channel by a desired base station. The UE  may send a request to reduce interference on the radio resources to an interfering base station, which may reduce its transmit power on the radio resources. The UE may receive the control channel on the radio resources from the desired base station and may observe less interference from the interfering base station.
