Title: System and method for flow diversion
Inventor: DANIEL MANWILL
IPC: E21B34/06
Filed: 2015-02-25
Abstract: A flow diverter including a bypass element to divert at least a first portion of drilling fluid from a drill string to the borehole annulus. The first portion of fluid, or bypass flow, may be provided to the borehole annulus to clear cuttings generated by a drill bit of a BHA. The remaining fluid flow, or BHA flow, may be expelled through the bottom of the BHA. The fluid discharged through the BHA may enter the annulus and flow upward with the fluid flow diverted through the flow diverter to aid in clearing cuttings. The flow diverter also includes a choke housing disposed concentrically within a drill collar and containing a plurality of chokes to regulate bypass flow. An actuation system may be coupled to the flow diverter to control opening/closing of the chokes and to measure flow rate of the first portion of fluid and/or the remaining fluid.

Inventor: XUSHENG WEI
IPC: H04W56/00
Filed: 2016-11-08
Abstract: Cell search and synchronisation is performed by initially detecting at least one first frequency span which then detects a first signal. A second stage of detection is then undertaken on at least one second frequency span, the at least one second frequency span being deduced by the signal detected in the initial detection. The at least one second frequency span is different from or identical to the at least one first frequency span. A second signal is detected during the second stage of detection and this second signal provides at least one of: a frequency associated with a cell; system information of a cell; and information indicative of the location of system information of a cell.                The initial detection may monitor a set of frequency locations spaced across said first frequency span at a first channel raster value.                             Further aspects of the invention provide the use of channel raster values to provide frequency locations of signals or channels in a wireless communication system and the use of frequency division multiplexing, FDM, and time division multiplexing, TDM, with synchronisation signals.                                             The cell search and synchronisation may be used in a 5G/New Radio (NR) wireless communication system.

Title: Brake calipers
Inventor: Anthony M Blackwell
IPC: F16D55/227
Filed: 2017-03-24
Abstract: Disclosed is a brake caliper 100 having a fixed part for attachment to a vehicle and a floating part movably mounted to the fixed part. The floating part includes a pair of spaced apart limbs 30, 31 and a bracing abutment. One of the limbs has an actuation means to apply a brake force for clamping, between the limbs, a pair of brake members 62a, 62b against a rotating disc. On application of a brake force by actuation means (which may be a piston), rotation of the brake disc exerts a drag force on the brake members, which causes at least one of them to brace against the bracing abutment. Each brake member may have their own respective bracing abutment. The limbs may be connected by a pair of bridging portions 32. The fixed and floating parts may be slidably connected by a drag force transmission pin which is orthogonal to the limbs and slidable within a bore (which is within first guide portion 40 in figure 9). The slidable connection may also include a guide pin secured within a bore (within second guide portion 50 in figure 9). The force transmission pin may be larger than the guide pin.

Title: A load dump
Inventor: RAYMOND JOHN PETO
IPC: H02H7/09
Filed: 2017-07-25
Abstract: The invention relates to a load dump, for example for connection to a dynamic brake resistor, and is especially useful when several motor drives and motors are operating together, interconnected in one system. The load dump includes an energy sink and a controller. The controller actuates a switch to divert current to the energy sink when a threshold is exceeded so as to dissipate excess energy in the sink. The load dump, at switch on, is at a voltage that is intermediate a voltage source and the load. The controller modulates the switch in dependence upon the quantity of energy to be dumped. The controller modulates the frequency of a waveform applied to the load so as to vary an intermediate voltage applied to the load at switch on. An advantage of this is that energy is dissipated at a very rapid rate independent of mains supply voltage.

Title: Safety system
Inventor: BENJAMIN IRELAND
IPC: G21C15/18
Filed: 2017-12-01
Abstract: A passive coolant injection system comprising a make-up tank 17 is disclosed, said system for use in a nuclear power plant including a reactor pressure vessel (RPV) 1 in fluid communication with a pressuriser 11 via surge line 13. During normal operation of the system, the make-up tank is maintained at the same pressure as the primary coolant circuit via pressure balance line 23 connecting a tank inlet 19 to the surge line, while a tank outlet 21 is isolated from the RPV by valve 27. Upon detection of a fault condition when the coolant level in the pressuriser drops below a threshold level, e.g. where one or more heaters 15 in the pressurizer are exposed, the injection system switches to isolate the tank inlet from the RPV by closing surge line valve 29, and simultaneously opens outlet line valve 25 so as to allow boronated water to flow into the RPV from the make-up tank, said flow being driven by residual pressure in the pressuriser.

Title: Method for intelligently selecting accounting node of blockchain
Inventor: KAI DUAN
IPC: G06Q20/06
Filed: 2018-06-20
Abstract: The application relates to selecting nodes to act as an accounting node in a blockchain, such as a delegated proof of stake blockchain. For each node, a node capability value is calculated based of block data. Each node’s capability value is compared to a threshold value, which is used to select an accounting node. Other nodes are randomly selected to complete the selection. The node capability value may include the node’s previous transaction amount, its processing capability, and its total service charge. The transaction amount may be calculated as a weighted sum of all previous blocks mined by the node. The processing capability may be a weighted sum of available storage space, processor speed and network bandwidth of the node.
