Patent GB-2512642-A (GB)
Title: A combustion chamber
Inventor: SPOONER MICHAEL PAUL
IPC: F23R3/06
Filed: 2013-04-05
Abstract: A combustion chamber 15 has an annular wall 40 with two rows of dilution apertures 58, 60 spaced apart axially. In each row, dilution apertures are circumferentially spaced, and each aperture has a polygonal cross-sectional shape, e.g. a triangle. Apertures in adjacent rows are staggered circumferentially, and a corner 62A of each dilution aperture in one row is axially upstream of a corner 64A of each dilution aperture in the adjacent row. The axial distance taken up by the two rows of dilution apertures in the annular wall is reduced compared to the use of two rows of circular dilution apertures and enables a greater mass flow of dilution air through a shorter axial distance giving better quenching of the rich burn combustion process and a reduction in nitrous oxide emissions.

Title: Method of estimating the injection pressure of an internal combustion engine
Inventor: PELIZZONI IVAN
IPC: F02M63/02
Filed: 2013-08-13
Abstract: The invention provides a method of estimating an injection pressure (or common rail pressure) for an internal combustion engine of an automotive system. The engine comprising a fuel injection system (165, fig.1), provided with a digital pressure sensor (400, fig.1), which periodically acquires injection pressure signals, the method calculating 560 an updated injection pressure value, RPcmp, starting from an injection pressure signal 500 and compensating it with a pressure correcting parameter, based on an elapsed time from the injection pressure signal acquisition, an actual engine speed 530 and an actual fuel injection quantity 540. Where digital sensors are used to measure the common rail fuel pressure they can cause a problem with respect to the ECU using a time based task to control the pressure measurements but using an angular based task (such as the crankshaft angle) for the fuel injection control, the invention provides a pressure correction parameter 550 to resolve the issue of the time interval between the pressure signal and other ECU angular based tasks.

Title: Address allocation for slave nodes connected in series
Inventor: HART SIMON DAVID
IPC: H04L12/403
Filed: 2013-08-16
Abstract: A computer network architecture comprises at least one master node 201 and at least one slave node 202, 203 serially connected downstream of the master node. Each slave node includes a switch 202b, 203b for connecting an upstream transmit line with a downstream transmit line at the slave node. Any slave nodes not yet allocated a unique slave address share a default slave address and have open switches. To allocate a unique slave address, the master node sends a message on the default slave address and the furthest upstream slave node having the default slave address is allocated a unique slave address. This slave node then closes its switch to connect the master node and any upstream slave nodes to any downstream slave nodes. The slave node allocated the unique address sends an acknowledgement to the master node. The process is repeated until all of the slave nodes have unique addresses.

Title: Door exit device, replacement for tubular latch with magnetic reed switch to exit a secure electrically locked door by using the existing or new lever handle
Inventor: HILL DAVID WILLIAM
IPC: E05B47/00
Filed: 2014-04-30
Abstract: A tubular / tube door latch has a cylindrical body containing a magnet.

Title: Subsea valve, flow system and method of use
Inventor: Stephen Barron
IPC: F16L55/38
Filed: 2014-10-30
Abstract: A flow system 200 (fig 4), a subsea valve 100, and a method of use in subsea pipeline filling, flooding or pigging operation. The flow system comprises a subsea valve comprising a main housing 101, with first 102 and second 103 ends, inlet 104 and outlet 105 configured to be coupled to subsea pipeline 13 (fig 4). The subsea valve comprises a movable valve member 133 and biasing mechanism 135, by which the valve member is urged by a biasing force towards a closed position that prevents flow of fluid through the valve and into the subsea pipeline. The valve member is operable to be moved to an open position on activation of the pump to provide pressure increase at the valve inlet sufficient to overcome the biasing force. In use, opposing sides of the valve member are exposed to ambient subsea pressure such that the subsea valve is pressure balanced. The valve may be used in a flow system with pump 112 (fig 4), comprising a pump inlet connected to a fluid source and a pump outlet connected to the valve inlet, operable to pump fluid from the fluid source and into the subsea pipeline via the valve.

Title: Synchronising devices
Inventor: Ravichandra Giriyappa
IPC: G06F1/12
Filed: 2015-09-09
Abstract: This invention aims to overcome the problem of keeping multiple devices synchronised on a network. It does this by having a controller 109b that modifies the clock signal from a first clock 108b. The controller has a time comparison unit 203 that estimates the time difference between a first signal that is associated with the first clock and a reference signal that is associated with a reference clock. If the time difference is greater than one clock period then the first, or integral, signal modifier 204 will modify the signal by an integer number of clock periods. If the time difference is less than one clock period then the second, or fractional, signal modifier 205 will modify the signal by a fraction of a clock period. The first signal modifier may do so by removing a number of pulses from the clock signal. It may also do so by delaying the clock signal by an integer number of clock periods.

Title: Controller and method
Inventor: JEREMY GREENWOOD
IPC: B60L15/20
Filed: 2016-03-22
Abstract: A controller 7 is used to control an electric machine 6 to drive a wheel 4 of a vehicle 1 (e.g. EV, HEV, PHEV, BEV). The controller includes a processor 15 that: determines an effective torque T at the wheel; receives a wheel speed signal 10 indicative of the wheel speed S; and outputs a speed demand signal 27 for controlling the wheel speed. The processor detects changes in the effective torque as the wheel speed changes and modifies the speed demand signal in dependence on the detected changes in effective torque. The processor may determine a derivative dT/dS of the effective torque with respect to the wheel speed. An inverter 5 controls the electric machine to force commutation at a constant speed. The current induced in the armature windings may be used to estimate the effective torque at the wheels. The inverter and/or the electric machine provide a feedback signal, comprising a commutation current signal and the phase angle of the electric machine, to a torque estimator which uses the commutation current and phase angle to estimate the effective torque at the wheel.
