Abstract: A subsea wellhead assembly for areas subject to iceberg scouring including an upper conductor 20 in a well bore 16 and a lower conductor 26 in the well bore with the upper end of the lower conductor being within the lower end of the upper conductor and connected thereto by a weak connection and the upper end of the lower conductor being below the maximum iceberg scour depth and means for connecting said conductors, said connecting means having sufficient strenght to withstand bending loads during drilling and being removable for installation of production equipment. Additionally production equipment in the well bore includes a block valve 40 supported within the second conductor and a production string 42 extending upward from the block valve 40 and having a weak point within the upper end of the second conductor whereby the well control is not lost by deep iceberg scouring since the production control equipment is within the second conductor which is not damaged by the scouring and the production equipment extending thereabove fails without damage to the lower control equipment of loss of the well.

Abstract: A pharmaceutical composition of a medicament, such as a 5-(pyridinyl)-2(IH) pyridone, in sustained release unit dosage form for oral administration. The composition is in the form of beads within a capsule of gelatin or the like. Each bead comprises an inert particulate core having adhered thereto a coating of particles of the medicament. This coating is in turn surrounded by a sustaining coating of three different polymers with different solubility profiles to allow a sustained release of the medicament both in the low pH environment of the stomach and at a higher pH values prevailing in the intestine.

IPC: H04M3/56

Abstract: This invention relates to a method to establish a conference connection between a plurality of conference nodes (2, 4, 8) arranged in a telecommunication network (1); and also to a node design (30; Fig 3) of such a conference node. The conference according to this invention is set up on a per call basis. Any of the conference nodes (2, 4, 8) shall, each time it activates, access a free information resource (11) among a plurality of resources (11, 12,...,n) and transmit it's message to this resource; while all the conference nodes during all the conference time, are listening to the messages present on all the activated or occupied resources. The maximum number of active (i.e. transmitting) conference nodes correspond to the total number of information resources. The maximum number of passive (i.e. listening) nodes are unlimited. A node is typically moving from a passive state to an active state and back again to the passive state leaving the resource unoccupied. Each resource may preferably be designed as a ring connection via which all the conference nodes are interconnected as the ring is looped through passive conference nodes, but where each activated ring connection is broken, only at one place, but in a dynamic manner, at the input of the active node associated with just this ring, which active node accesses this particular resource during the activated time period of just this node. The invention is well suited for digital crypto conferences, as speech decoding and decrypting is undertaken at each conference node input, while encryption and speech coding is done at each conference node output. In addition the invention is easily adapted to an Integrated Services Data Network (ISDN). Echo suppression, as well as addition and subtraction of conference signals, are totally avoided. The crypto keys to be used in such a crypto conference, may be distributed among the conference participating nodes before the conference starts; and/or they may be altered during the conference, in short lasting pauses in the conference, or on a free resource, or via the D-channel in the ISDN implementation. <IMAGE>

Granted: 1996-10-22
Abstract: An exchange route decision system and method which, when it is desired to realize tandem connection between outgoing and incoming communication terminals of various sorts and multiple rates requiring immediate data communication through a plurality of exchanges, take the residual capacities of relay lines between the outgoing and incoming terminals into consideration.  In the system and method,  the residual capacities of the relay lines between the outgoing and incoming terminals are divided into a plurality of classes based on predetermined line capacity units, data on routes providing minimum costs in association with the classes are controlled.   Boundary values of each of the classes are separately controlled at residual-line-capacity increasing and decreasing sides. Updating operation of the route data in association with the classes takes place only when a change in the residual line  capacity  exceeds  the  capacity  increasing  or decreasing boundary value of the class.

Granted: 1995-05-30
Abstract: A graphics display image is displayed on a display.  The graphics display image is formed by a plurality of graphics display image components, at least some of which have to be edited.  The graphics display image components may be generated from data obtained e.g. from the optical reading of a hard copy of a map, circuit diagram, or design drawing by a suitable optical reader.  The graphics display image components which are to be edited are displayed with a different visual appearance from any components which do not have to be edited, e.g. by highlighting the components to be edited.  As the editing of each of the components is completed, its visual appearance is changed, e.g. the highlighting is cancelled, so the operator has an immediate visual indication of the components which have not yet been edited.  In this way, complete editing can be ensured.          Different editing operations are possible including creating a cursor corresponding to the component to be edited, adjusting that cursor to correspond to the location, size and orientation of the component to be edited, and replacing the component with the cursor image.
