Title: An aircraft propulsion system and a method of controlling the same
Filed: 2011-08-22
Abstract: An aircraft propulsion system (100) has a propulsive rotor assembly (20, 80) rotatable about an axis of rotation (24) and comprising a plurality of blades (22, 82) and a rotationally fixed vane assembly (60) located adjacent to the propulsive rotor assembly and arranged circumferentially around the axis of rotation. As airflow enters the propulsive rotor assembly, a portion of the airflow passes over the vane assembly which is configured to direct the airflow away from the rotor blades so as to reduce the relative velocity of the redirected airflow over the rotor blades. This results in a reduced tendency of the airflow through the propulsive rotor assembly to become choked.

Title: Graphene foam based solar heat exchanger
IPC: F24S10/40
Filed: 2012-05-01
Abstract: A solar heat exchanger comprises a fused quartz glass tube containing a graphene foam 5 and water 4, where the water, which is to be heated by solar energy, is in direct contact with the graphene foam. In operation, the graphene foam is designed to absorb energy from incident sunlight, heat up, and transfer the heat into the surrounding water. Preferably, the glass tube comprises an inner tube 2 and an outer tube 1, with a vacuum 3 maintained in the space between the inner and outer tubes so as to minimise heat losses and maximise heat absorption. A further graphene coating 6 may be included on the inside surface of the inner tube. Water may be pumped through the inner tube of the heat exchanger and around the graphene foam. The graphene foam may include a metal substrate, which can either be melted out to leave the graphene foam as the only structure or left in place to make the foam a darker colour for improved solar heat absorption. Preferably, the graphene foam comprises a rolled up sheet or stacked layers of graphene. A Fresnel lens (7, fig.2) may be used to concentrate solar energy onto the heat exchanger.

Title: Application recovery in file system
Filed: 2012-01-13
Abstract: Embodiments of the invention relate to block layout and block allocation in a file system to support transparency of application processing. At least one copy of an application is replicated in a write affinity region of a secondary server, and at least one copy of the application is replicated in a wide striping region across a cluster file system. When the application is subject to failure, application processing is transferred from the failure location to the write affinity copy. At the same time, the failed application is rebuilt using the wide striping replication of the application. Once the application is rebuilt, processing may return to the failed location employing the rebuilt application.

Patent DE-3273359-D1 (DE)
Title: Sintered metal body and method of making same
Inventor: GONZALEZ RICARDO
IPC: B22F3/26
Filed: 1982-09-14
Granted: 1986-10-23
Abstract: A sintered metal body, having an annular form suitable for use as a valve seat or seal, is impregnated (13) with an uncured polymeric material such as PTFE which is then cured to partially fill the interparticulate spaces in the sintered metal body. The impregnated body is then subjected to applied pressure (16) which preserves the annular shape of the body while collapsing substantially all voids throughout the body to cause the cured polymeric material within the sintered metal body to completely fill the collapsed interparticulate spaces thereby to render the body nonporous throughout. In as much as the interparticulate spaces are completely filled with cured polymeric material, any increases in temperature of the body which result in an expansion of the polymeric material cause a migration of portions of that material from the inferior of the body to the exterior surfaces of the body to lubricate the exterior surfaces. The body may, in addition, be completely covered by another layer of cured polymeric material to give the seat additional initial lubricity (17).

Patent DE-3483890-D1 (DE)
Inventor: SOUSSAN DAVID BEN
IPC: G08B19/00
Filed: 1984-01-06
Granted: 1991-02-14
Abstract: An electronic temperature controller having a great stability and an improved sensitivity to temperature. The controller is designed to operate at preset temperatures depending on the occupancy and/or the presence of light in each of the rooms of a household. A microcomputer supplies control signals to a heating device until the ambient temperature in the room reaches the appropriate preset temperature. To do so, use is made of an electronic regulator of the proportional-integral-differential type. The control signals of course control the amount of energy (i.e. heat) given off by the heating device in the room. This electronic controller permits to regulate temperature automatically and thus save heating energy when the rooms of the house are either unoccupied or not lit. This electronic controller may also incorporate an electronic thermometer, an alarm system and/or a fire alarm. It may also control any appliance in a room depending on a change in occupancy and/or lighting in the room.
