Title: Portable radio receivers
Inventor: CHAMBERS JOHN PHILIP
IPC: H04H20/88
Filed: 1989-12-18
Abstract: A portable radio receiver (10) has a single loudspeaker means (12) and means for receiving a stereo radio signal (14). Switching means (16) are provided for transmitting selectively to the loudspecker means (12) either a monophonic component of the stereo radio signal or one of the "right" and "left" channel signals derived from the stereo radio signal for stereo reproduction. The radio receiver may, thus, be used either to reproduce a monophonic sound or, if used as one of a pair of appropriately-switched receivers, to provide stereo reproduction. When used as a pair, the receivers can be positioned to give the best possible stereo effects if there is no physical connection between them.

Title: Method and tool for remote replacement of a pipe module
Inventor: HOEGLUND KJELL
IPC: F16L1/26
Filed: 1990-02-12
Abstract: A tool used for diverless replacement of a pipe module (2) forming part of a pipeline system (5, 6) disposed on a bottom plate (1) located on the seabed comprises a supporting plate (29) and a telescopic frame (Figure 3) connectible thereto. The tool is lowered down and placed over the pipe module (2) which is to be replaced by means of a tool carrier. A coupling (33) on the tool engages a gripping head (28) on the pipe module. With the aid of screwdrivers on the tool, clamp couplings (11), connecting the pipe module to pipe ends of the pipeline system leading to said pipe module, are disconnected. The telescopic frame comprises two end plates (52, 53) which, by means of telescopic arms located therebetween, are capable of changing their intermediate distances with the aid of screw jacks. The end plates have internal slots which surround the push lugs on the pipe ends. After the clamp couplings have been disconnected, the pipe ends can be pushed apart by means of the end plates, the pipe module thus being disengaged from the pipeline system and, after the supporting plate and the telescopic frame have been disconnected, is capable of being raised to the surface with the tool carrier and the supporting plate for replacement. When a new pipe module is to be installed, the procedure is reversed. <IMAGE>

Patent GB-2246269-A (GB)
Title: Telecommunication network
Inventor: MCCOMBE MICHAEL JOHN
IPC: H04W8/04
Filed: 1990-07-20
Abstract: In a cellular telephone system, subscribers each have a token (such as a smartcard) by means of which they may respectively identify themselves to the network. Each subscriber logs into the network by using his smartcard which inputs a unique secure identification number (IMSI) into the network. The relationship between each IMSI and the corresponding subscriber's telephone number (MSISDN) is random and known only to the network operator, this arrangement facilitating simple and secure issue of initial and replacement smartcards. A home location register (HLR) in the network stores each subscriber's MSISDN and the associated IMSI. The network also includes an analysis table linking each IMSI with the identity of the corresponding HLR storage location. This analysis table is split into parts which are held at different entities, such as different mobile services switching centres (MSC), in the network. In response to an input IMSI, the relevant MSC controlling the cell receiving that IMSI derives from the IMSI a Global Title which it uses to locate the relevant part of the analysis table. It can now access the correct storage location in the HLR, extract the MSISDN (and other subscriber data) and store this temporarily in its associated visitor location register.

Title: A metallization process using amorphous titanium nitride layer
Inventor: LEE SANGIN
IPC: H01L23/532
Filed: 1990-10-01
Abstract: The metallization process is characterized in that an amorphous titanium nitride layer (10) is formed between a titanium layer (7) and an aluminium layer (5) either by carrying out a reactive-sputtering from a titanium target containing another larger sized metal atoms, or by carrying out a cosputtering from both a titanium target and another metal target. According to the present invention, the formation of metal spikes can be inhibited, and therefore, the occurrence of current leakage and the destruction of the junction can be prevented. <IMAGE>
Patent GB-2256314-A (GB)
Title: Charge density wave semiconductor device
Inventor: WILLIAMS DAVID A
IPC: H01L31/00
Filed: 1991-01-25
Abstract: The device consists of a silicon substrate (10), a thermal oxide layer (11), lower gate electrodes (12a, 12b) with a spacing (W) that defines a channel region (C) and an oxide layer (13) on which an upper gate (14) is formed. In use, bias potential is supplied to the lower gate (12) and the upper gate (14) so as to establish an inversion region in the lower oxide layer (11) which is confined to a longitudinal channel (C) by the bias potential applied to lower gate (12b). A quasi one- dimensional electron gas is confined within the channel by a potential across its width in which a charge density wave can be established. The configuration of the lower gate electrodes (12a, 12b) is such that there is a longitudinal spatial modulation of the confining potential applied to the charge density wave. When the charge distribution wave has a wavelength which corresponds to the spatial distribution, the channel (C) will exhibit a relatively high conductance but otherwise conductance between the contacts (15a, 15b) is lower. The device is suitable for use as a photodetector. <IMAGE>

Title: Pressure sleeve for reduction of digital swelling
Inventor: RASBURN NEIL WILLIAM
IPC: A61F5/34
Filed: 1991-04-04
Abstract: Accidental or surgical trauma to the body, generally gives rise to swelling. Because finger joints are surrounded by tendon and ligament only and, therefore, lack the hydromechanical action of muscle to reduce the swelling of the joint, such joints are particularly prone to prolonged swelling which prevents correct flexion of the finger. By rolling a device comprising a hollow fluid-filled sleeve having a continuous and endless elastomeric wall (12) formed as two tubes (12A, 12B) one inside the other and connected together at respective ends, back and forth along the finger from tip to base, accumulated intracellular fluid is urged towards the lymphatics hence reducing the swelling. The device may be inflated using an inflation tube (18) with a self-sealing valve (20). <IMAGE>
Patent GB-2246933-A (GB)
Title: Production of multi-layered video composite
Inventor: SEYMOUR MICHAEL
IPC: G06T13/00
Filed: 1991-04-17
Abstract: A multi-layer video composite is formed on a frame-by-frame basis by loading a background frame into a background frame store (14), loading a frame of the next layer into a foreground frame store (12) and supplying the outputs to a compositor (18). The composited layers are looped back to the background frame store and a frame of the next layer is loaded into the foreground framestore (12). The layers may be buffered in a RAM (22) to increase processing speed. Once the final layer in the foreground frame store has been composited with the previous layers in the background frame store the composite is output. The foreground frame store includes a digital video effects generator to enable interactive editing of each layer. The source of each frame and the edit and composite sequence is stored so that after composition any layer can be edited interactively by separating that layer from the composite and editing it in the DVE. <IMAGE>
