Title: Sinter for use in iron-making and/or steel-making
Inventor: Daran Graves
IPC: C22B7/02
Filed: 2018-07-27
Abstract: A method of making particles which can then be sintered and used to make iron or steel by collecting dust particles discharged from iron-making and/or steel making and washing them in water which comprises 2.5-25 % by weight of the particles, whereby the chloride content of the particles is reduced from 0.06-0.5 % by weight to 0.0005-0.06 % by weight. Figure 2 shows apparatus for this method where particles P are fed onto a screen 230 in a rinsing tank 270. Oversize particles F1 (size greater than 5mm) are screened out and pumped as a suspension to a hydro-cyclone 310 which rejects undersized particles (size less than 0.032 mm), with the rest of the particles being fed onto a vibrating dewatering screen 320 where they are dried. The dried particles Pout can then be used to make sinter.

IPC: H03K17/66
Filed: 2020-02-05
Abstract: A switch control circuit for controlling one bidirectional switch (Fig.9) is configured, upon receiving an OFF signal, to turn off a positive direction of the switch after a time t+OFF and turn off a negative direction of the switch after a time t-OFF; it is further configured, upon receiving an ON signal, to turn on the positive direction of the switch after a time t+ON and turn on a negative direction of the switch after a time t-ON. The positive and negative direction switch ON/OFF times may be dependent on the direction of current flow (Fig.10) and allow for safe 4-step commutation between two switches. A multi-switch control circuit comprises a plurality of switch control circuits, each controlling a respective single bidirectional switch, and a master control unit. When power is to be commutated from a first switch with input voltage V1 to a second switch with input voltage V2 the master control unit sends an OFF signal to the first switch control circuit and an ON signal to the second switch control unit; the respective switch control units may control the positive and negative direction turn ON/OFF times based on the input voltage difference V2-V1 with respect to zero. The switch control circuits are modular and may be used in applications such as AC-AC conversion.

Title: Improvements in and relating to localisation in a telecommunication network
Inventor: MYTHRI HUNUKUMBURE
IPC: H04W64/00
Filed: 2021-02-17
Abstract: A method of performing localisation of a User Equipment, UE, or a device in a telecommunication network, comprising a step wherein a client sends a composite location service, LCS, request to the telecommunication network, the composite location service request comprising a Quality of Service, QoS, class for location services comprising multiple sets of QoS requirements. The class with multiple QoS requirements is a location QoS class and relates to: a plurality of zones, with a QoS requirement associated with each of the plurality of zones; and/or a plurality of QoS requirements wherein if a location estimate obtained does not fulfil a most stringent QoS requirement, then the localisation estimate is repeated with a less stringent QoS requirement. A Gateway Mobile Location Centre, GMLC, obtains context information relating the UE and selects an Access and Mobility Management Function, AMF, to execute composite location service request with the multiple QoS class. Multiple QoS class defines a new third QoS class, to operate alongside known localization QoS classes, Assured QoS class and Best effort QoS class. Embodiments of the invention reduce the latencies involved with localization service messages, reducing overall end-to-end latencies required for Industry IoT, IIOT, applications having strict end-to-end latency requirements.

Filed: 2021-06-18
Abstract: The processing of audio signals, e.g. in an audio equaliser, is disclosed. A first adjustable gain amplifier 202 is configured to receive a feed-forward signal from an input 131. A second adjustable gain amplifier 203 is configured to receive a feedback signal from an output 135. A gain controller 204 supplies gain control signals to the adjustable gain amplifiers 202 and 203. The gain 1/G applied by the second adjustable gain amplifier 203 may be the reciprocal of the gain G applied by the first amplifier 202. A first combiner 205 combines the outputs of the first and the second adjustable gain amplifiers 202 and 203. A plurality of filters 211, 212, 21N are connected in parallel, each filter receiving the output of the first combiner 205. The filters have mutually different filtering characteristics. A second combiner 221 combines outputs of the filters with the original input signal. The arrangement allows volume levels to be maintained while rearranging the frequency distribution of the original signal. The arrangement also provides a filter characteristic with plateaux separated as widely as possible with extended transition shape over a wider frequency range.

The stop carrier 43A has a first longitudinal axis CX1A and the mounting section 47A has a second longitudinal axis MX1A inclined at an angle α1 relative to each other, allowing pivoting about an intersection 59 to bias the stop 37A towards a stop position. Methods of installation/removal of the handle mounting assembly include applying a force to the stop locating member, pivoting the pivot link in a first direction, and pivoting the pivot link in a second direction. A release tool (81, figs 8A-C) has an offset head and recess so stop carrier 43A can be held in a depressed position and the pivot link 27A pivoted so that a stop engaging member 29A prevents the stop 37A returning to the stop position.
