Patent GB-2239919-A (GB)
Title: Pipe swivel joints
Inventor: MCCANN JAMES PETER CAROL
IPC: F16L39/06
Filed: 1991-02-13
Abstract: The invention relates to pipe swivel joints of the kind suitable for use in the oil industry in situations where a sub-sea well is connected to a surface vessel by complex pipe lines, twisting of which must not occur when the vessel ''weather-vanes''. An example of a joint comprising inner (2, 4) and outer (1, 3) toroidal members with a fluid pasage (13) defined by confronting faces of the members, dynamic (17, 18) and silt (15, 16) seals being provided, wherein the confronting faces include complementarily contoured stepped annular regions which together define a gap therebetween, each step of each annular region comprising an annular land (L) disposed in a radial plane of the joint unit. The land (L) of adjacent steps are of differing diameters. In a particularly useful arrangement, the inner and outer members each comprise a first unit portion (1; 2) providing the surface defining the passage and two flanking portions (3; 4) providing the stepped regions.

Title: Location registration and paging procedure for mobile communication
Inventor: TAKETSUGO MASANORI
IPC: H04W68/00
Filed: 1991-02-20
Abstract: To reduce location registration traffic between mobiles 1 and base stations BS1 ... BS23 ... in respective zones Z1 ... Z23..., overlapping location areas PA5, PA8... are defined each including a plurality of zones. When a mobile effects location registration with a base, it stores a location information signal sent by the base and including codes of zones in the location area whose reference is that base zone, (Figs 4 to 10). When the mobile moves into another zone, it effects a new location registration only if the ID code of that base zone is not included in the location area currently stored by the mobile. Alternatively, the mobile stores the ID code of the last zone at which it effected location registration, each base continuously transmits ID codes of zones in the corresponding location area, and on moving into a new zone a mobile effects a new location registration only if the zone ID it has stored is not in the ID list transmitted by the new zone's base, (Figs 11 to 14). Each mobile has a route memory storing ID's of zones it has been in since the last location registration. At the next registration, the route information is transmitted to the base and from that information the base stores cumulative numbers for each zone, the zones in the associated location area at any time being determined by the set having greater cumulative numbers. The number of zones in a location area may be increased as registration traffic to the corresponding reference base increases, and/or decreased as ringing traffic from a control centre 4 to the base increases, (Figs 18 to 21). The control centre 4 may store ID's of the zones at which all mobiles last registered. On receiving a call to a particular mobile, centre 4 sends the corresponding registration zone ID to all bases, and each base which includes that zone in its current location area transmits a paging signal to the mobile (Figs 15 to 17). <IMAGE>

Title: Valve assembly to be used in a subsea structure, particularly a mudmat
Inventor: PEDERSEN HAKON
IPC: E02B17/00
Filed: 1993-07-12
Abstract: A valve assembly to be used in a subsea structure 8, particularly a mudmat, has a valve closing disc (2) hung, with limited free play, from a support member (2). The support member is provided with pivotable connecting hooks (16) engaging with a flange (7) on the subsea structure, thereby securing the support member and valve closing disc to the subsea structure 8. By means of a central tightening screw (17) the valve closing disc may, when the hooks are in gripping engagement with to the flange, be pressed down so as to bear against a valve seat formed by the free annular surface (6) of the flange. In the open position of the valve assembly, the valve closing means are held in a position above the flange (7) by means of a rod (12) which extends downward from the valve closing means and penetrates a hub sleeve (11) in the aperture, and which may be locked in an open position there. When the through aperture 10 in the subsea structure is to be be closed, the holding engagement between the rod (12) and the hub sleeve (11) is released and the support member (2) and valve closing disc will then sink down toward the flange, whereby the connecting hooks (16) achieve underlying gripping engagement with the flange. <IMAGE>

Title: Satellite navigation
Inventor: KYRTSOS CHRISTOS T
IPC: G01S1/00
Filed: 1993-10-20
Abstract: The position of a satellite 102 in a satellite based navigation system 200 is determined without reliance on satellite ephemeris data. Orbital parameters are computed for each satellite 102. The orbital parameters can then be used to predict the position of each satellite 102 at any time. Subsequent ephemeris data may be compared to a predicted satellite position to determine whether the ephemeris data is corrupt The orbital parameters may be determined by: computing a pseudorange and a velocity for a selected satellite 102 for a plurality of times, computing at least three estimated positions of the satellite 102 from the pseudoranges and velocities, and computing orbital parameters for the satellite from the three estimated positions. In another embodiment, the orbital parameters are determined by: determining the position of a receiver 212 for at least three times using a constellation of satellites 102, using the three receiver positions to triangulate on an average position for the selected satellite 102 in the constellation, repeating these steps until at least three mean satellite positions have been computed, computing the orbital parameters from the three mean positions of the selected satellite 102. <IMAGE>
