Patent GB-2561564-A (GB)
Title: Method
Inventor: ANDREAS CHRYSANTHOU
IPC: C22F1/08
Filed: 2017-04-18
Abstract: A method of forming sub-surface micro-plastic deformations in a metallic material such as steel, aluminium or brass by application of dry sliding friction. The dry sliding friction can be applied to a sheet of metal as it is shaped (for example bent, flanged, stretched) in areas where stress forms during the shaping, thus reducing the amount of energy needed to perform the shaping process, reducing springback of the sheet and reducing its bending radius. Figure 5d shows a tool 516 which is slid along the bend line of a sheet of metal 518 with the opposite side of the bend being located on a support 530. Dry sliding friction can also be applied to relieve tensile stress present in a workpiece, for example by locating tools 316 on opposite sides of a cold drawn tube 318 and rotating the tube or sliding a tool along a weld (Fig. 16a). It can also be applied to a workpiece under tensile stress. After the stress is removed compressive stress exist in the workpiece (Fig. 18).

Title: Vehicle roundabout management
Inventor: PERRY ROBINSON MACNEILLE
IPC: G08G1/16
Filed: 2017-10-19
Abstract: A first phantom or ghost vehicle 12AP is projected into one of a branch and a circle lane of a roundabout 98 in association with a first autonomous vehicle. The first autonomous vehicle 12A is caused to enter the circle lane 100 upon predicting no collision with oncoming vehicles. The first autonomous vehicle is caused to exit from the roundabout. The method may further involve merging or melding (Fig.7, 12E, 12EP) the autonomous vehicle into the phantom vehicle, once the vehicle enters the roundabout. The method may also select a particular branch lane 104 for the autonomous vehicle to enter and exit the roundabout. A platoon of phantom vehicles may be created to form a queue of vehicles 12H-K entering the roundabout or in a circle lane. This may allow vehicles to flow regularly through the roundabout by controlling the platoon to move through the roundabout when a vehicle has been waiting in the queue for a certain amount of time or to maintain a certain distance between vehicles.

Title: Rotating control line cutting sub
Inventor: ALASDAIR R TAIT
IPC: E21B29/04
Filed: 2016-05-04
Abstract: A control line cutting tool is mounted for rotation in response to lifting the cut segment. The blade is oriented to cut as the cutter is forced to rotate to follow a spiral groove in the portion of the body below the cut. When the follower pin in the cutter reaches the end of the spiral slot all the control lines have been cut with minimal stress on the control lines to accomplish the cut. The pin then enters a longitudinal slot to allow separation of the body above the cut from the remaining portion in the borehole supported by a packer.

Title: Reconfiguration of inertia, damping, and fault ride-through for a virtual synchronous machine
Inventor: QINGCHANG ZHONG
IPC: H02M7/521
Filed: 2018-01-14
Abstract: A controller for reconfiguring the inertia, damping and fault ride-through capability of power converter operating as a virtual synchronous machine (VSM). Virtual inertia Hv(s) is reconfigured by adding a low-pass filter to a torque (power) channel and virtual damping is reconfigured by adding a virtual damper between the VSM voltage e and the output voltage ePWM sent to PWM conversion. The fault ride-through capability is reconfigured to achieve a desired fault-current level by reconfiguring the damping and the inertia. The controller comprises a torque/active power channel that takes a negative torque/active power feedback signal to generate a frequency signal, and a reactive power-voltage channel that takes a negative reactive power feedback signal to generate a field excitation signal. A calculation block generates a VSM voltage, a torque/active power signal and a reactive power signal. A virtual inertia block takes the torque/active power signal from the calculation block and generates the negative torque feedback signal for the torque/active power channel. The virtual damper takes the VSM voltage, a feedback voltage and/or the converter-side inductor current from the power part of the converter and generates an output voltage to drive the power switches of the converter after PWM conversion

Title: Catalytic wall-flow filter having a membrane
Inventor: GUY RICHARD CHANDLER
IPC: F01N3/28
Filed: 2016-06-20
Abstract: A catalytic wall-flow monolith 1 for an emission treatment system comprises a porous substrate with first 15 and second 25 faces defining a longitudinal direction therebetween and first and second pluralities of channels each open at a respective face and closed at the other and providing respective inner surfaces. A catalytic material is distributed within the whole or between 85 to 95 % of the length of the porous substrate and a microporous membrane 36 is provided on the channel surfaces. The membrane has pores smaller than soot i.e. 0.1-5 micron and allows a surface soot layer but prevents build-up within the larger substrate pores and thus prevents back-pressure build-up. This allows soot induced backpressure to build within uncoated or thickened coating regions and limits soot collection to manage exothermic effects on regeneration. The layer extends from the first face along the length of the first plurality of channels and may decrease or increase in thickness with distance from the first face.
