Title: Wireless communication systems
Inventor: ZHOU YUEFENG
IPC: H04B7/155
Filed: 2006-10-13
Abstract: In a wireless communication system, subscriber or mobile stations (MS) communicate with a base station (BS), which can perform simultaneous communications with a number of connected subscriber stations by allocating an available capacity among them. The subscriber stations are required to issue capacity requests in order to obtain and/or maintain a connection with the base station, and communications between the subscriber stations and the base station are performed partly or wholly through at least one relay station (RS1#, RS2#). The method involves, in the relay station, detecting capacity requests issued from a plurality of the subscriber stations and/or other relay stations, using the detected requests to form at least one combined capacity request, and transmitting the combined capacity request to the base station. The base station responds to the combined capacity request by reserving capacity for said plurality of subscriber stations, and the relay station or the base station allocates the reserved capacity among the plurality of subscriber stations.

Title: Address translation using an intermediate node and a database of fixed and temporary addresses
Inventor: MACHIN SAM
IPC: H04L29/12
Filed: 2007-02-23
Abstract: Two devices, e.g. a mobile device and a home computer, connected in a network, have temporary IP addresses assigned from a pool of addresses and which may alter with each successive connection. The devices register (steps 2.1-2.3) details of their fixed identifiers (e.g. MSISDN, CLI) in a database which generates a mapping between the two identifiers. On creation of a new connection, IP addresses assigned to each device are communicated to the database and stored in an entry corresponding to the fixed identifiers. Messages between the two devices are sent via an intermediate fixed network node. Applications in each device are configured to send messages having the assigned IP address as the source address, and the intermediate node address as the destination address. The intermediate node receives the message, queries the database for the correct destination IP address of the recipient, and forwards the message with the recipient IP address as the destination address and the intermediate node address as the source address. The intermediate node may also carry out load balancing by using a plurality of address translation servers.

Title: Method of riser deployment on a subsea wellhead
Inventor: PALMER LARRY T
IPC: E21B17/01
Filed: 2007-05-25
Abstract: The riser assembly (14) is plugged adjacent its bottom (20) end either as it is made up or after full makeup or anywhere in between. A heavy fluid (26) is either added to the riser string as it is made up or delivered into the string after makeup to displace seawater or other fluids that may have been in the riser as it is assembled. The floating rig (10) can be secured over the subsea well head (12) and the riser now full of heavy fluid is less prone to be displaced by wave action and preferably simply dangles straight down so that the connection to the subsea wellhead can be simply accomplished. The effect of wave action is minimized or eliminated when deciding placement of the floating rig with respect to the wellhead. Repositioning of the rig takes less effort and is needed less frequently.

Title: A silencing arrangement
Inventor: LIDDELL SARAH HELEN
IPC: A47L9/00
Filed: 2009-02-27
Abstract: In an appliance, such as a cyclonic vacuum cleaner 1, a motor is arranged to drive an impeller fan located in a motor and fan unit 3. The rotation of the impeller may cause nuisance tones to be generated. A silencing arrangement is provided to control such noise and comprises a plurality of discrete passive silencers in the form of tube silencers 23 arranged in a first set 18 and a second set 24. The tube silencers 23 have open end portions arranged to face the fan and the silencers of the first set 18 are spaced from the silencers of the second set 24 in both axial and radial directions. This combination gives the same effect as an array of closely spaced tube silencers, however, by spacing the silencers in two directions, fluid is allowed to flow freely.

Title: Clutch control device for a circular knitting machine
IPC: D04B15/94
Filed: 1976-03-15
Abstract: 1525055 Controlling clutch-brake combinations ELITEX 15 March 1976 [3 April 1975] 10223/76 Heading F2L [Also in Division D1] A control for a clutch-brake combination in the drive to the needle cylinder of a circular knitting machine comprises an electromagnetically operated valve 13<SP>1</SP> which selectively supplies pressure air to the air chamber of a hydropneumatic clutch actuating cylinder 10 or to the air chamber of a hydro-pneumatic converter 12, the liquid chamber of which is connected to the liquid chamber of the cylinder 10 through a throttle valve 11 and parallel one-way valve 13. With the valve 13<SP>1</SP> in the position shown, air is supplied to the converter 12 and the liquid displaced therefrom flows through the throttle valve 11 to the cylinder 10 and acts through a piston 9 and linkage 6, 7, 8 to move an axially slidable clutch-brake plate 2 into engagement with a driving clutch disc 1. The rate of clutch engagement is determined by the throttle valve 11. When the valve 13<SP>1</SP> is changed over, pressure air is supplied to the cylinder 10 and the liquid displaced therefrom flows rapidly through the one-way valve 13 to the converter 12. The plate 2 is thus rapidly disengaged from the disc 1 and engaged with a brake disc 3. The valve 13<SP>1</SP> is acutated in response to machine failure as manual control. The linkage is connected to the plate 2 by rollers carried by the yoke 6 engaging a groove in the periphery of the plate 2.
