Title: Bonding of aluminium-based material using gallium
Inventor: GHOSHUNI AMIR ABBAS SHIRZAKI
IPC: B23K35/26
Filed: 2001-11-29
Abstract: This invention provides a new method for flux-free brazing of aluminium using gallium. This method requires non-abrasive smearing of liquid gallium 1 onto a faying surface of a piece of aluminium-based material 2. Preferably, the aluminium pieces 2, 3 are then quenched, eg in liquid nitrogen, to stop further diffusion of the liquid gallium into the aluminium pieces. Then bonding is carried out in air by pressing the pieces of aluminium together with fast heating, (  /  200{C/minute) and maintaining them at a temperature between 200 - 600{C for a few seconds under a controlled pressure.

Title: Calibration of a transmitter or receiver in a transceiver wherein transmitter signals may be detected via the receiver or a separate detection arrangement
Inventor: NEWTON ANTHONY DAVID
IPC: H04B17/00
Filed: 2002-07-05
Abstract: The invention relates to gain calibration in a transceiver unit (100) having a transmitter unit and a receiver unit and a feed back coupling (165) between these. A signal level measurement unit (163) measures signal levels of a feedback signal through either the receiver unit or through a signal level detector (167). A reference signal level of the feedback signal is set by adjusting the transmitter until the signal level measurement unit (163) measures a predefined value when connected through the signal level detector (167). An absolute value of the transmitter gain is then calibrated. The signal level measurement unit (163) is connected through the receiver unit and the absolute gain of the receiver is calibrated. A gain is changed either in the receiver or the transmitter unit. The relative signal level change of the feedback signal is measured and used to calibrate the gain step.

Title: Relay
Inventor: FONG ARTHUR
IPC: H01H29/02
Filed: 2002-10-25
Abstract: A piezoelectrically actuated relay 100 that switches and latches by means of a liquid metal 170 operates by means of a longitudinal displacement of a piezoelectric element 150 in extension mode displacing a liquid metal drop 170 and causing it to wet between at least one contact pad 160 on the piezoelectric element or substrate and at least one other fixed pad to close the switch contact. This motion of the piezoelectric element 150 is rapid and causes the imparted momentum of the liquid metal drop 170 to overcome the surface tension forces that would hold the bulk of the liquid metal drop 170 in contact with the contact pad or pads 160 near the actuating piezoelectric element 150. The switch 100 latches by means of surface tension and the liquid metal 170 wetting to the contact pads 160. A magnetostrictive element may be employed.

Title: Generating multiple bandgaps using multiple epitaxial layers
Inventor: YANSON DAN ANDREYEVITCH
IPC: H01S5/026
Filed: 2003-12-24
Abstract: A quantum well intermixing (QWI) technique for modifying an energy bandgap during the formation of optical semiconductor devices enables spatial control of the QWI process so as to achieve differing bandgap shifts across a wafer, device or substrate surface. The method includes: forming a substrate comprising one or more core layers defining at least one quantum well; depositing a succession of intermixing barrier layers 20 - 24 over the quantum well, each successive intermixing barrier layer being formed of a semiconductor material and having a different etch characteristic than an immediately preceding barrier layer; etching away different numbers of the successive barrier layers in different regions of the substrate so as to provide different total thicknesses of barrier layer in different regions of the substrate; and applying an intermixing agent 40 to the surface of the substrate such that the degree of intermixing in the quantum well region varies as a function of the total thickness of barrier layer, thereby forming different bandgaps BG0 - BG3 in the quantum well in each of the respective regions.

Title: Making anti-microbial lyocell fibres containing silver and phosphate
Inventor: VEGAD HIRAN
IPC: D01F2/00
Filed: 2004-03-19
Abstract: Anti-microbial lyocell fibres are made by a process in which a particulate anti-microbial agent of silver ions held in a matrix of a phosphate glass is mixed into an ingredient or precursor of the spinning solution. This gives improved distribution of the agent and allows the addition of the agent in dry powder form, so helping to limit premature loss of the soluble agent from the system. In a preferred system, the spinning solution is made by forming a pasty pre-mix of cellulose pulp and amine oxide solvent and the agent is mixed into the pre-mix or into an ingredient of the pre-mix.

Title: Decoding a concatenated convolutional-encoded and block encoded signal
Inventor: HUGGETT ANTHONY RICHARD
IPC: H03M13/29
Filed: 2004-05-26
Abstract: Encoded symbols of a concatenated convolutional-encoded and block encoded signal 21 are presented to a conventional first stage 20 of a concatenated decoder 300, comprising in sequence a soft metric generator 22, a Viterbi decoder 23, a first de-interleaver 25 and a first block decoder such as a Reed-Solomon decoder 26. The encoded symbols 21 are also presented to a delay chain to produce progressively delayed encoded symbols. Where an output block of the conventional decoder 20 is indicated as being a valid codeword by the first block decoder 26, the bytes in this block are marked as being correct. These bytes that are known to be correct are then used after interleaving and serialisation as known bits input to a second stage 30' of the decoder process operating on the delayed encoded symbols 21' and incorporating a modified soft metric generator constrained by the known bits. This process can be extended to further iterations as required. A modified Viterbi decoder, which is also constrained by the known bits, may also be used in the second and subsequent iterative stages.

Title: Collection of Automatic Meter Readings dependent upon spare capacity of exisiting networks
Inventor: SHELLEY CHRISTOPHER
IPC: G01R/
Filed: 2004-07-01
Abstract: The remote collection of data for the account of an entity (2) uses a data communications network (26) operated by a third party (28) with respect to the entity. It is characterised in that the access to said data communication network (26) by the entity for remote data collection is governed dynamically by said third party (28) as a function of the spare data-carrying capacity of the communications network. The third party (28) may thus grant the entity (2) access to the communications network (26) when the level of the third party's own data traffic on said network is below a determined threshold value, corresponding to an occupation below peak capacity. The approach finds applications notably in the field of automatic meter reading (AMR), where the network operator, e.g. a cellular telephone operator, is a third party with respect to the utilities company (2), and the collected data is meter reading data from remote meters (14a-14g) sent via GPRS interfaces (16a-16d).
