Title: Rotary machine with means for separating impurites from a gas flow
Inventor: BENNETT IAN
IPC: F04D29/52
Filed: 2002-07-19
Abstract: A rotary machine, such as a compressor or a turbine, comprises blade rows which impart a high swirl component in a gas flow 10. The swirl component causes dense impurities in the gas flow 10 to be deflected radially outwardly on to an inner wall of a stator 16. The inner wall of the stator 16 includes a surface which guides the separated impurities from a gas intake side of the machine towards a gas outlet side. The guide surface includes radial steps 30 to prevent the reverse flow of impurities back towards the gas intake side of the machine. The radial steps 30 may only extend around part of the circumference of the stator 16. The rotary machine may be a down hole compressor which is used to extract gas from a well, and the impurities my be liquid droplets or solid particles.

Title: Synchronising database entries in distributed bridging fabric units and ageing inactive entries
Inventor: WEYMAN RAPHAEL J
IPC: H04L49/111
Filed: 2004-05-27
Abstract: A network unit for use in a distributed bridging fabric has a multiplicity of user ports for the transmission of data frames to and from an external network and at least one fabric port for the transmission of frames between the network unit and another unit in the fabric. The network unit has a forwarding database for containing entries each including a media access control address, and a lookup engine organized for the insertion of an entry into the forwarding database when the network unit receives a data packet at a user port. The unit broadcasts via each fabric port of an "address added" message identifying a respective media access control address (MAC). The lookup engine also responds to such an "address added" message received from another unit to make a corresponding entry in the database and to annotate an entry to indicate activity of an address in response to an address which is already in the database. The network unit has an aging engine organized for the polling of entries in the database. The aging engine refreshes an entry for which the respective media access control address is annotated as active and is organized for the selective removal of inactive entries from the database. Keywords- switching fabric, bridging fabric, ageing.

Title: Processor with delayed branch resolution
Inventor: KADAMBI SUDARSHAN
IPC: G06F9/38
Filed: 2003-02-04
Abstract: A processor (402) avoids or eliminates repetitive replay conditions and frequent instruction resteering through various techniques including resteering the fetch after the branch instruction retires, and delaying branch resolution. A processor (402) resolves conditional branches and avoids repetitive resteering by delaying branch resolution. The processor (402) has an instruction pipeline (916) with inserted delay in branch condition and replay control pathways. For example, an instruction sequence that includes a load instruction, followed by a subtract instruction then a conditional branch, delays branch resolution to allow time for analysis to determine whether the condition branch has resolved correctly. Eliminating incorrect branch resolutions prevents flushing of correctly predicted branches.

Title: System and method for frequency management in a communications device having a positioning feature
Inventor: GOLDBERG MARK A
IPC: H04W64/00
Filed: 2003-09-30
Abstract: A frequency management scheme for a hybrid cellular/GPS or other device generates a local clock signal for the communications portion of the device, using a crystal oscillator or other part. The oscillator output may be corrected by way of an automatic frequency control (AFC) circuit or software, to drive the frequency of that clock signal to a higher accuracy. Besides being delivered to the cellular or other communications portion of the hybrid device, the compensated clock signal may also be delivered to a comparator to measure the offset between the cellular oscillator and the GPS oscillator. The error in the cellular oscillator may be measured from the AFC operation in the cellular portion of the device. An undershoot or overshoot in the delta between the two oscillators may thus be deduced to be due to bias in the GPS oscillator, whose value may then be determined. That value may then be used to adjust Doppler search, bandwidth or other GPS receiver characteristics to achieve better time to first fix or other performance characteristics.
