Title: Extracting transistor
IPC: H01L21/338
Filed: 2000-05-19
Abstract: An extracting transistor (10)-an FET-includes a conducting channel extending via a p-type InSb quantum well (22) between p-type InAlSb layers (20, 24) of wider band-gap. One of the InAlSb layers (24) incorporates an ultra-thin n-type delta-doping layer (28) of Si, which provides a dominant source of charge carriers for the quantum well (22). It bears n<+> source and drain electrodes (30a, 30b) and an insulated gate (30c). The other InAlSb layer (20) adjoins a barrier layer (19) of still wider band-gap upon a substrate layer (14) and substrate (16) with electrode (18). Biasing one or both of the source and drain electrodes (30a, 30b) positive relative to the substrate electrode (18) produces minority carrier extraction in the quantum well (22) reducing its intrinsic contribution to conductivity, taking it into an extrinsic saturated regime and reducing leakage current.

Title: Sealing method and apparatus
IPC: E21B33/134
Filed: 2002-03-28
Abstract: A method and apparatus for forming a plug in a passageway. The apparatus comprises a carrier which in use is lowered into the passageway, the carrier comprising an elongate body of a material resistant to creep which supports at least two spaced apart portions that are a sliding fit in the well such that a gap is formed between each of the portions and the passageway. A body of material the melting point of which is higher than the temperature within the passageway and which expands as it solidifies is supported on the carrier. A heating device is provided for melting the body of material such that the melted material fills a space defined between the first and second portions. The carrier is cooled preferentially to ensure that the molten material solidifies rapidly adjacent the two spaced apart portions, thereby resisting flow of the material as it solidifies past the spaced apart portions. Means are provided to obstruct the gaps formed between the portions and the passageway, the obstructing means being displaced into the gaps as a result of melting of the body of material or as a result of any creep of material after it has been melted and solidified.

Title: Electrochemical treatment of ammonia in waste-water
IPC: C02F1/461
Filed: 2003-09-15
Abstract: In a sewage treatment plant, dissolved ammonium is extracted from the waste-water stream, and is transferred to a body of secondary water. The secondary water is passed through an electrolysis station, where the ammonium is transformed to nitrogen gas. The capture and transfer can be done by ion-exchange, the electrolysis then being done on the regenerant water. Or the capture and transfer can be done by first transforming the dissolved ammonium to ammonia gas by raising the pH of the waste-water, then passing the ammonia gas through acidic secondary-water, in which the ammonia dissolves, the electrolysis then being done on the acid-water. The electrolysed, ammonium-diminished, secondary-water can be re-used in further capture/transfer episodes. The secondary-water does not mix with the waste-water stream. <IMAGE>

Title: A method of friction welding
Filed: 2006-08-08
Abstract: A method of friction welding comprises providing a first workpiece having a first weld surface and a second workpiece having a second weld surface. The first workpiece is arranged such that it tapers away from the first weld surface, the first workpiece converges in a direction away from the first weld surface. The first and second workpieces are arranged such that the first weld surface abuts the second weld surface. The first and second workpieces are oscillated relative to each other such that at least one of the weld surfaces of at least one of the workpieces moves relative to the other weld surface of the other workpiece such that the temperature increases at the weld surfaces to create a weld interface. The oscillation is stopped and the first and second weld surfaces are allowed to cool to weld the first and second workpieces together. The tapering of the first workpiece reduces the flow rate of weld flash material during the oscillation of the first and second workpieces relative to each other to reduce the formation of strain-induced porosity at the edges of the weld.

Title: Gripper-jacquard axminster carpet loom
IPC: D03D39/08
Filed: 1989-01-19
Abstract: A carpet loom of the gripper-jacquard Axminster type includes a shogging mechanism (21) to shog the grippers (3) and/or the yarn carriers (1) transversely between successive picks of pile yarn. By shogging the grippers (1) transversely between successive picks of pile yarn a different gripper is used in each course for successive picks. Equally, when the yarn carriers (1) are shogged the pile yarns that form each course are not taken from the same yarn carrier (1). Thus, any fault on the grippers (1) or in the yarn in one carrier (1) will not result in a fault on a single course throughout the entire carpet but will, instead, be dispersed between a number of different courses.

Title: Communications systems
IPC: H04B1/707
Filed: 1989-07-13
Abstract: In a communications system employing HF radio transmission a message to be transmitted is subjected to time spreading modulation prior to transmission. The time spreading modulation results in processing gain at the receiver with either resultant transmission range increase, which is particularly beneficial in the case of inefficient antennae, or limited transmitter power, or permitting lower power to be used for a predetermined transmission range. A message 5 at a first bit rate is multiplied at 6 by a pseudo random spreading sequence 7 at a higher bit rate, and the resultant data stream is modulated at DPSK modulator 4 prior to transmission. <IMAGE>

Title: Radio communication system
IPC: H04W4/12
Filed: 1989-10-30
Abstract: A radio communications system, particularly a cellular system, has base stations BS for providing a bi-directional radio communication link with a mobile station MS. A messaging centre SCM is connected to the base stations for storing an incoming message for forwarding to a mobile station using the system. Each mobile station MS has a timer, and during a low power consumption "off" state of the mobile, the timer periodically switches the mobile to an on state to effect a location registration update communication procedure with the base station network. In response to this communication, the messaging centre SCM is caused to send any stored messages to the mobile via the base station network. <IMAGE>

Title: Method and apparatus for the formation of particles
IPC: B01J2/04
Filed: 1994-06-30
Abstract: The invention provides a method for forming particles of a substance, by co-introducing into a particle formation vessel, in which the temperature and pressure are controlled, of a supercritical fluid; a solution or suspension of the substance in a first vehicle; and a second vehicle which is both substantially miscible with the first vehicle and substantially soluble in the supercritical fluid, in such a way that dispersion of the solution or suspension and the second vehicle, and extraction of the vehicles, occur substantially simultaneously and substantially immediately on introduction of the fluids into the vessel, by the action of the supercritical fluid. Preferably the solution/suspension of the substance is introduced separately from the second vehicle, in such a way that contact between the solution/suspension and the second vehicle occurs either substantially simultaneously with, or immediately before, their dispersion by the supercritical fluid and extraction of the vehicles by the supercritical fluid. The method allows a high degree of control over the size, shape, crystalline form and other physico-chemical properties of the particulate product. The invention also provides apparatus for carrying out such a method, using a coaxial nozzle to introduce the fluids into the particle formation vessel, and a particulate product made using the method or the apparatus.
