Title: Nuclear shielding materials
Inventor: BASELEY ALAN
IPC: G21F1/12
Filed: 1995-04-11
Abstract: A neutron absorbing fabricated plate comprises a hermetically sealed casing containing a neutron absorbing layer 4 made from a mixture of at least two materials, one being a matrix powder material, e.g., a corrosion resistant material such as stainless steel, and one being a neutron absorbing powder material such as boron nitride. The manufacturing process involves compacting the powder mixture into blocks (4), assembling them into the casing (1,2,3,5), and hot-rolling the assembly after it has been sealed and evacuated. This enables the neutron absorbing layer to retain some ductility after manufacture, so facilitating post-forming of the plates. Compacts formed of only a corrosion resistant powder material can also be assembled into the casing so that compacts (4) containing the radiation absorbing material can be excluded from contact with regions of the casing where potentially disruptive joining processes between panels, such as fusion welds, will later occur.

Patent GB-2324436-A (GB)
Title: A connectionless communications network accommodating various grades of quality of service
Inventor: MAUGER ROY HAROLD
IPC: H04L12/801
Filed: 1997-08-01
Abstract: A connectionless network capable of accommodating various grades of quality of service (QOS) is operated and controlled by a virtual model of the network. Congestion and admission of calls with different QOS requirements is controlled by the virtual network. In a satellite network a virtual model is provided comprising a mesh of connected virtual nodes. As the satellites move, each virtual node becomes embodied by a different satellites. Calls are routed through the nodes with modelled virtual paths corresponding to virtual circuits in the real network. QOS class 1 and class 2 calls have reserved bandwidth. Call admission control (CAC) determines if there is available bandwidth to admit a new call at call set-up. No alternative path routing is allowed during a call. For class 3 calls a maximum or mean bandwidth is reserved end to end and may be renegotiated according to demand. QOS class 4 calls have the lowest priority, operate on a best effort principle using TDMA and have no effective bandwidth reservation. The percentage bandwidth capacity for each QOS class can be renegotiated to achieve a different grade of service (GOS) for each QOS.

Title: Interference cancellation system for global positioning satellite receivers
Inventor: CASABONA MARIO M
IPC: H04B7/185
Filed: 1997-02-13
Abstract: An adaptive polarization cancellation arrangement which nulls out all types of concurrent interference signals received by a Global Positioning System (GPS) receiver from antenna mainlobe and sidelobe situated sources. The orthogonally polarized components of the composite received signal are separated by the receive antenna (5) arrangement and adjusted in the polarization feed adapter network (7, 9, 15, 17) between the antenna and GPS receiver to optimally cancel components. The antenna and installation arrangement creates a polarization filter relative to interference sources which changes their apparent polarization orientation and supports adaptive discrimination based on dissimilar polarization characteristics relative to the desired signals. The orthogonal received signal components from the GPS satellite constellation and from interference sources are combined to adaptively create cross-polarization nulls that adequately attenuate interference sources while slightly modifying the GPS received signals. The present network can also improve GPS signal levels and signal to noise ratio by polarization optimization or matching in non-interference environments.
