Patent GB-2522777-A (GB)
Title: Novel purification processes
Inventor: KERR JOHN
IPC: C13B20/02
Filed: 2014-12-19
Abstract: A process for the removal of contaminants, such as colour bodies, from a liquor comprises a combination of two or more of carbonatation, phosphatation and sulphitation of the liquor to form a precipitate comprising at least some of the contaminants from the liquor. The process also comprises separation of the precipitate from the liquor. The process may be utilised in a sugar refining process or as a water decontamination process. Preferably, the process involves the introduction of phosphoric acid or sulphur-based acid into the liquor; and the introduction of carbon dioxide into the liquor. The carbon dioxide gas can be introduced into the liquor by bubbling or, alternatively, the carbon dioxide may be generated by adding a metal carbonate to the liquor which will react with phosphoric acid in the liquor. If the carbon dioxide is introduced into the liquor by bubbling, then the carbon dioxide can be recycled and reintroduced into the liquor. A foam or froth flotation step can be utilised to separate the precipitate from the liquor. Suitably, a surfactant is introduced into the liquor. The amount of precipitate can be moderated by the addition of a calcium salt.

Title: Wafer bow reduction
Inventor: PETER WARD
IPC: H01L21/20
Filed: 2015-01-14
Abstract: Reducing the bow in a composite wafer comprising a silicon wafer and a silicon carbide layer grown on the silicon wafer, by applying nitrogen atoms during the growth process of the silicon carbide layer to generate a compressive stress within the composite wafer. The compressive stress reduces the natural tensile stress in the system and thus reduces the bowing of the wafer. The nitrogen atoms may be applied substantially across the entire wafer. The nitrogen atoms may not form part of the doping concentration of the silicon carbide layer. The nitrogen atoms may be applied during the silicon carbide growth phase. The silicon carbide layer may be a 3-step cubic silicon carbide (3C-SiC). The layers may be used to make a semiconductor device such as diode, or a transistor.

Title: Wellhead annulus seal having a wickered surface
Inventor: GETTE NICHOLAS PETER
IPC: E21B33/04
Filed: 2014-02-21
Abstract: An annular seal (22, 22A) for use in a wellhead assembly (10) has inner (28) and outer (30) legs that each extend in a direction that is generally parallel with an axis of the seal to define an annular space therebetween. Wickers (34, 38) are provided on an outer surface of the seal, so that when the seal is energized and the legs are urged radially apart from one another, the wickers engage with a mating surface of a downhole tubular (16). Embedding the wickers into the tubular creates a flow barrier across the interface between the seal and the tubular. The wickers deform the surface of the tubular, which creates a lock down force that opposes relative axial movement of the tubular.

IPC: H01Q13/10
Filed: 2016-06-22
Abstract: An aperture coupled patch antenna has a patch radiator 19 and a feed line 21, operating as a transmission line, located on opposite sides of a ground plate 25. The ground plate has an aperture 3 which allows signals to be coupled from the transmission line on one side of a ground plate to the patch radiator on the other side. The aperture has the form of a slot, the thickness, t, of the ground plate at the slot being larger than the width of the slot, w. A thick ground plate provides mechanical strength and allows the ground plate to be manufactured economically using, for example, casting which is not suited to producing thin sheets as would be required with a conventional thin ground plate. The aperture slot may also be I-, H- or dog-bone- shaped (see fig 2A). The patch radiator may be carried on a non-conductive film 2. The transmission line may be carried on a thin non-conductive film 5. A conductive cover plate 8, electrically connected to the ground plate, may further be provided on the opposite side of the transmission line to shield radiation from the transmission line.

Title: Boiler inhibiting
Inventor: ALISDAIR CUMMING
IPC: F24H9/20
Filed: 2016-07-27
Abstract: A domestic boiler 10 for heating water has a maximum thermal output during normal operation and a designated service interval between successive maintenance checks. The boiler 10 comprises a controller 22 which has a resettable service interval timer 30 for monitoring a time since a preceding maintenance check. On expiry of the designated service interval since the preceding maintenance check, the controller 22 maintains continued operation of the boiler 10 at a reduced maximum thermal output. On resetting of the timer 30 the boiler 10 is returned to normal operation. The maximum thermal output of the boiler 10 may be reduced by reducing a maximum power output, limiting a flow of fuel or reducing the temperature of water supplied from the boiler 10. The timer 30 may be reset by a secure key comprising a code which may be input by a keypad or digital card reader, or by a switch on a PCB in the boiler. A boiler comprising a device to disable an external control and a method of commissioning a boiler is also claimed.

Title: Method and system for differentiating macro-bend losses from splice and connector losses in fiber-optic links
Inventor: MADHAN THOLLABANDI
IPC: H04B10/071
Filed: 2017-03-27
Abstract: The method includes generation of modulated optical pulses and scrambling the state of polarization of the modulated optical pulses to random states of polarization. The modulated optical pulses are injected in at least one test fiber and Rayleigh backscattered optical pulses are received and split by a polarization beam splitter into two orthogonal optical components. The power of each optical component is measured and discrete values of polarization dependent loss as a function of distance along the fibre are calculated. Macro-bends and stresses are identified by analysing peaks in plots of traces of the values of polarization dependent loss. The macro-bend loss events are differentiated from the splice and connector loss events. Electrical signals corresponding to backscatter may be synchronously resampled and filter to improve the signal-to-noise ratio. Sensitivity may be increased by shifting the optical carrier wavelength from O-band to U-band. Each discrete value of the polarization dependent loss may be calculated from a logarithm of a ratio of the two measured powers.
