Title: Production of filtration-active fibres
Inventor: LEIBNITZ RUEDIGER
IPC: D01F6/60
Filed: 2000-12-08
Abstract: A process and a device for producing filtration-active fibers are described. An aqueous suspension is produced from a homopolymer of polyacrylonitrile, polyamide or cellulose acetate and the suspension is heated in a tank to a temperature T which is at least 60{ above the boiling point of the water and at least 30{C below the softening temperature of the polymer. The at least plasticized polymer mass obtained is discharged through at least one nozzle means at least using the autogenous pressure of superheated water. The suspension is prepared in a storage tank 2, and the aqueous polymer suspension is heated under pressure in a mixing tank connected to the storage tank 2. Nozzle means 16 for discharging the plasticized polymer mass is located at the output of the mixing tank 10.

Title: Location specific group calls in a telecommunications system
Inventor: VALENTINE STEPHEN
IPC: H04W4/06
Filed: 2002-01-17
Abstract: A mobile telecommunications system allows the set up of flexible groups within defined locations e.g. an area covered by a cell having a base station. When a mobile station MS enters the location and attempts registration, it is assigned a location specific group identification code 308, which is transmitted and received 310 by the MS. The mobile station stores the code in its scan list and thereafter monitors the appropriate signalling channel for the presence of the code as part of a paging address. On receipt of the code 314 the MS is enabled to join the location specific group call 318. The invention allows the setting up of groups within specified areas, without the use of area defining fields in the communications protocol, these not being standardised amongst different providers. Further the setting up of the groups does not require expensive reprogramming of the mobile stations on changing groups. The invention can be applied to TETRA, UMTS or other third generation communication systems. The mobile units may be any kind of radio device, e.g. mobile phone, PDA or wireless connected computers.

Title: Method for determining parameters of earth formations surrounding a well bore
Inventor: GAO LI
IPC: G09B29/00
Filed: 2003-04-04
Abstract: A method for determining a formation conductivity profile surrounding a well bore includes receiving (30) field log data for the formation and generating a Jacobian matrix (40) responsive to the log data. A new formation conductivity profile is generated (50) using the Jacobian matrix and this profile is compared (55, 60) for convergence with the log data. A quasi-Newton update (70) is used to update the Jacobian matrix if the log response does not converge with the log data and this step is repeated until the generated formation conductivity profile converges with the log data. The method is less intense computationally than previous methods.

Title: Establishing a communication link in a digital communication system
Inventor: FRANDSEN SVEND HENRY
IPC: H04B7/185
Filed: 2003-11-21
Abstract: Where a difference exists between delay times of links in a communication system, problems may be encountered at call setup. For example a first mobile unit (not shown) may be associated with a base station 102 linked to the network infrastructure 104-106 via a satellite link, whereas a second mobile (also not shown) is associated with a base station 108 connected by a landline. In this case simultaneous issue of channel grant messages will mean that the shorter link mobile is enabled to transmit before the longer link mobile is ready to receive, resulting in loss of initial speech, or no synchronisation data being received e.g. when encrypted speech is being sent, which prevents decryption. Also, where large link delays are encountered, special conversation rules should be used, but if the users are unaware of the use of a long delay link, these rules cannot be introduced until the conversation is well underway and problems have arisen. The invention avoids this by delaying transmission in the shorter delay link. This can be done by delaying channel grant signals 112 to the shorter link until the longer link has acknowledged after a delay 302. Alternatively the transmission can be buffered at any point in the chain. The delay would normally be twice the difference in delay link times and can be communicated by the network to the terminals. The delay can be pre-known or measured when needed.
