Title: Method and device for stripping ammonia from liquids
Inventor: BONDE TORBEN A
IPC: C02F1/58
Filed: 2003-08-01
Abstract: The present invention in a first aspect provides a method and a system for stripping volatile compounds such as ammonia from e.g. fermentation liquids.  Part of the ammonia is stripped form the liquid in a stripper system comprising a shunt through which liquid such as e.g. fermentation medium comprising a biomass can be diverted in the form of a side stream in liquid contact with a main fermentor(s). The stripper system is connected to an evaporator. In the evaporator aqueous liquid is heated at a pressure below atmospheric pressure whereby vapour is developed at a temperature below 100~C.  The vapour from the evaporator is directed to the liquid medium comprising ammonia and this results in ammonia being stripped from the liquid and transferred to the vapour phase. The vapour phase is condensed in first condenser at a low pressure, e.g. a pressure well below 1 bar, and the liquid thus obtained is further treated in a stripper unit at a higher pressure, such as e.g. a pressure at or above 1 bar, to obtain a more concentrated solution of ammonia. When stripped for at least part of the ammonia the liquid initially obtained from the biogas reactor and diverted to the shunt can be returned to the reactor.

IPC: G06F12/02
Filed: 2004-08-31
Abstract: Sector writing operations in the alternative memory block (AB) follow sequentially. The position of the respective sector in the alternative memory block, is stored in a sector table. Conversion of altered addresses is effected using a data record with a real block address (RBA) and sector table in the internal flag memory of a memory controller. The sector table is formed as an index table (IT). In this, the real sector address (RSA) serves as the index. Valid sector position is indicated in the alternative block (AB) at the respective table position. The maximum value in the index table (IT) points to a sector address (RSA) where the associated sector remains unaltered in the original memory block (SB). The sector table is constructed as a search table (ST). In each table entry the real sector address (RSA) is indicated by the respective valid sector position in the alternative block (AB). The search table (ST) is ordered in accordance with real sector addresses (RSA). The position of the sector in the alternative block is also stored in the control area of the sector. During restarting of the memory system, the sector table of a block is re-formed from the sector positions stored in the control area. During restarting, the position of the sector with the highest position number in the sector table is converted. A memory block contains 256 sectors and the associated index table is 256 bytes long. The corresponding search table is 32 bytes long. Further variants of the method are described in accordance with the foregoing principles. Salient points include the use of file allocation tables (FAT) and sector masking strategy.

Title: Fuel vapor systems for internal combustion engines
Inventor: DALE THOMAS D
IPC: F02G5/00
Filed: 2004-12-17
Abstract: Pressurized fuel vaporizers for engines. Fuel is vaporized under substantial super-atmospheric pressure. Surfaces (S) are heated by the engine~s electrical system. Vapor heated by a wall (60) bounding a vaporization space turbulently mixes with incoming liquid spray, helping to produce new vapor. Useful for cold start, liquid spray reaching a rapidly heated impact plate (70) is vaporized. Multiple heat-transfer surfaces are exposed to the same vapor volume, one, a surface of revolution surrounding the spray, another, a transverse surface across the spray. The spray is in pulses. Glow plugs (G;  G1; 702) are arranged perpendicular to heat-distributing members (62, 70, 704). A volume-surrounding wall receives heat from an annular medium, e.g. an annular conductive plate (62) or an annulus of phase change material (404), such as low melting point metal, e.g. sodium. Air is shown excluded from the pressure chamber. A fuel vaporizer (700) dedicated to a single combustion region has a cup-shaped vaporization chamber heated by a central heater (702) in opposition to liquid spray. Bottom (704) and side (706) surfaces of the cup are constructed to promote mixing circulation. Liquid fuel injection is synchronized with timing of the engine. In such a system also having a vapor injection valve (736B) synchronized with engine timing, the internal between operation of the valves is controlled to enable heat-transfer to vaporize the fuel and build up pressure. The heating coil of a glow plug is electrically insulated form, but thermally conductively related to, its exterior tube predominantly by fine powdered glass (804) and the exposed seal of the glow plug is pressure-sealed by high temperature seal glass (808).
