Title: Device for filtering fluids containing impurities
Inventor: WENDELIN GEORG
IPC: B29C48/03
Filed: 1997-12-03
Abstract: The invention relates to a device for filtering fluids, notably plastified, thermoplastic materials, containing impurities, particularly in the form of solids. Said device comprises a case (1) containing at least one fixed, substantially level filter (5). The fluid to be filtered is fed to the filter (5) in the area around its periphery by means of at least one inlet channel (3). The filtered fluid is led out of the case (1) via at least one outlet channel (7). At least one scraping element (17) is pressed with its scraping edge (31) against the inlet-facing surface (11) of the filter (5), and is movably fixed to a support (12) which can be rotated by a drive element (15) around an axis (14) substantially perpendicular to the inlet-facing surface (11) of the filter (5). The scraping element (17) scrapes off the impurities adhering to this surface (11) and moves them to the centre of the filter (5). from where then are evacuated by means of at least one endless screw (38) via at least one evacuation channel (39) starting at the centre of the filter (5) and leading out of the case (1). At least one scraping element (17) is fixed on a support (12) in such a way that it pivots around an axis (18) and sticks out from said axis in the direction of the rotation of the support (12) and at an oblique angle to the filter (5). The scraper edge (31) of the scraping element (17) is pressed against the filter (5) when the support (12) rotates as a result of the counter-pressure generated by the fluid to be filtered. This effectively prevents blockages of the scraping elements (17).

Title: Radio network access mechanism
Inventor: VIRTANEN KARI
IPC: H04W8/08
Filed: 1999-01-28
Abstract: A method of registration in a telecommunications system by a mobile station, which system comprises a home location register (HLR) for maintaining subscriber data and supports a first network, such as GSM, and a second network, such as GPRS. The home location register (HLR) maintains the mobile subscriber data and a message (2-6a, 4-3) is sent to the home location register (HLR) for requesting the mobile subscriber data. According to the invention, the home location register (HLR) maintains an access parameter (PARAM) which indicates whether the mobile subscriber is entitled to use the first network, the second network or both networks. In response to said message for requesting the subscriber data, the home location register sends the mobile subscriber data and also said access parameter. The network element that requested the mobile subscriber data uses said access parameter for restricting the access of the mobile subscriber only to a circuit-switched network and/or to a packet-switched network.

Patent CA-2300895-A1 (CA)
Inventor: PORTER JOHN DAVID
IPC: H04W88/08
Filed: 1998-08-24
Abstract: Data transmissions take place in a radio communication system between at least one base station and at least one remote station. The base station is able to transmit signals to and receive signals from the remote station whilst the remote station is in a predetermined area. A priority is assigned to each type of data to be transmitted and the type and priority of each forthcoming transmission is determined and stored. Data types of the highest priority are then transmitted prior to data types with lower priorities. Where there is more than one base station there will be a plurality of overlapping communication cells. The base stations broadcast signals in a first time period and remote stations transmit signals in a second time period. The base stations are coupled to a central controller which synchronises the first and second time periods used by the base stations in adjacent cells. The number of transmissions in each cell is monitored and the durations of each of the first and second time periods adjusted to improve the use of available transmission bandwidth. Transmissions from remote stations to base stations may be transmitted after a predetermined delay which is varied in dependance on the distance of the remote station from the base station.
