Title: Fluid pressure indicator with leakage path that reduces Helmholtz resonance
Inventor: ANGUS DOUGLAS JOHN
IPC: G01L19/06
Filed: 2011-08-03
Abstract: Pressure indicator 40 comprises a first reservoir 42 defining a first enclosed volume (i.e. pressure tapping) 44; first inlet pipe 46 connecting the volume to a first source of pressurised fluid 50; and passage 64 that provides a flow path for the fluid. It may comprise a second reservoir 52 defining a second enclosed volume 54 and a second inlet pipe 56 connecting it to a second pressure source 60. A pressure transducer 62 may be in communication with the first or both enclosed volumes. The passage may connect the two enclosed volumes (Fig.2); the two inlet pipes (Fig.3); or the first volume and either a further source of pressurised fluid (84, Fig.4) or a point downstream of the inlet pipe (Fig.5); such that the flow induced in the first inlet pipe is no more than 10% or 1% of the flow rate of the fluid source. The leakage path provided by the passage damps any pressure oscillations in the pressure tappings and alters their natural frequencies.

Title: Display apparatus for an article and an associated electronic image
Inventor: TERRY PAUL
IPC: G09F27/00
Filed: 2011-08-05
Abstract: A display apparatus 10 comprising a picture frame 12 containing a space 24 for an article to be displayed, an electronic image display unit, and at least one of (a) a control unit 32 for controlling the image display unit 28, and (b) a battery unit 38 for powering the image display unit.

By decoupling the image display unit from its control unit(s) and/or battery unit(s), each unit can be of a smaller size so that there is a greater choice as to the location of each unit. Furthermore, the image display unit, for example, can be positioned off-centre in the frame, and other unit(s) can be positioned so that the centre of gravity of the whole apparatus lies on the vertical centre-line of the frame, so that the frame can be suspended from a single central point and will hang straight.

Title: Extended drx time periods for machine-type communications using an absolute timing reference
Inventor: JOKIMIES MATTI KULLERVO
IPC: H04W24/10
Filed: 2011-08-16
Abstract: In one aspect, a wireless device (10) sends a synchronization group identifier to a network control apparatus (40,70,80) identifying a synchronization group of wireless devices. If the wireless device (10) is notified that no other devices of the synchronization group are connected to the control apparatus (40,70,80), the wireless device (10) transmits a timing reference to and agrees an extended discontinuous reception (DRX) time period with the control apparatus (40,70,80). Otherwise, the wireless device (10) receives a timing reference and an extended discontinuous reception time period from the control apparatus (40,70,80). The wireless device (10) periodically enters an idle state and powers up for reception in accordance with at least the timing reference and the extended discontinuous reception time period. In another aspect, plural base stations (40) each use a common timing reference and a common extended discontinuous reception time period in controlling the operation of extended discontinuous reception by a synchronization group of wireless devices (10). In particular the invention lies in using DRX time periods for machine-type communications (MTC).

Title: A classifier and a method of modifying a classifier for use with a pulveriser
Inventor: GOOSEN PIERRE
IPC: B02C23/12
Filed: 2013-12-03
Abstract: A classifier 10 or cyclone separator 10 which normally takes in a feed of particles from a pulveriser, features a larger particle rejection gate 35 formed of two or more closure members 37 moveable between a closed position (fig.2) and an open position (fig.4). Larger reject particles, such as for recirculation into the pulveriser, accumulate in the rejection gate 35, weighing on the closure members 37, causing them to open and allow passage of the larger particles. The closure members 37 may be fitted with weights 40 which bias the closure members 37 into a closed position, and are relatively long and slim so as to be aerodynamic. In this manner the closure members 37 may return to closed positions, after material has passed between them. The particles may be of coal to be fed to a power generating furnace.

Title: Detection method and apparatus
Inventor: JOHNSTON JAMES THOMPSON LAWSON THORNTON
IPC: G01S3/801
Filed: 2013-12-16
Abstract: A method of detecting and identifying acoustic events, for passive submarine sonar. Simultaneous collection of acoustic data from a plurality of acoustic sensors is combined to form a plurality of beams. The beam data for each respective beam is processed using DEMON processing to produce a signature for each beam. Either the beam or the signature is tagged by different colours or symbols with the associated bearing data. The tagged beams or beam signatures from a particular time interval are combined to provide a waterfall spectrogram showing the combined outputs from consecutive time intervals to indicate any acoustic event(s). This provides an operator with a combined view across a substantial part of the acoustic array.

Title: Frequency error
Inventor: BAGNALL PETER
IPC: H03L1/02
Filed: 2013-12-20
Abstract: An input receives a frequency having first and second frequency components, described as a target frequency and a frequency error. A filter block has filter coefficients describing a relationship between the second frequency component and an environmental characteristic, e.g. temperature. The filter predicts the first frequency component based on the environmental characteristic and updates the coefficients based on an offset between the predicted first frequency component and a received frequency corresponding thereto. In an embodiment, a GNSS receiver includes an acquisition / tracking block 101, an oscillator 103, a temperature sensor 104 and a frequency compensator 102. The compensator 102 incorporates a Kalman filter that includes a model of the oscillator 103. Based on this model, the compensator provides a predicted oscillator frequency 109, and also updates the accuracy of the model using an indication of temperature 107 from the sensor 104 and an offset value 108 which may indicate a difference between a predicted frequency and a target frequency, e.g. a GNSS frequency. The model may predict a compensation (not shown) that should be applied to the frequency generated by the oscillator 103.
