Patent EP-4283809-A1 (EP)
Inventor: HART PHILIP JOSEPH
IPC: H02J3/00
Filed: 2023-05-09
Abstract: A method for controlling a network of inverter-based resources connected to a power grid during a disturbance includes employing a distributed transient virtual impedance algorithm among the network of inverter-based resources (IBRs) after a start of or in anticipation of the disturbance. The distributed transient virtual impedance algorithm includes determining, via at least one of one or more power flow equations, one or more energy function equations, and one or more estimated power capabilities, a virtual impedance control parameter and a modified power reference for one or more of the IBRs. Further, the method includes activating the virtual impedance control parameter and the modified power reference for one or more of the IBRs to ride through the disturbance in a manner that also optimizes use of the one or more estimated power capabilities for one or more of the IBRs and that preserves synchronism between at least two of the inverter-based resources and/or between at least one of the inverter-based resources and the power grid. Thus, the virtual impedance control parameter temporarily reduces voltage proportionally with output current for one or more of the IBRs, thereby resulting in a reduction of local power output of one or more of the IBRs.

Abstract: A method of correcting angles of a welding torch positioned by a user while training a robot of a robotic welding system is provided. Weldment depth data of a weldment and a corresponding weld seam is acquired and 3D point cloud data is generated. 3D plane and intersection data is generated from the 3D point cloud data, representing the weldment and weld seam. User-placed 3D torch position and orientation data for a recorded weld point along the weld seam is imported. A torch push angle and a torch work angle are calculated for the recorded weld point, with respect to the weldment and weld seam, based on the user-placed torch position and orientation data and the 3D plane and intersection data. The torch push angle and the torch work angle are corrected for the recorded weld point based on pre-stored ideal angles for the weld seam. The method also comprises displaying augmented reality symbols overlaid onto an image of the weldment indicating the location of the weld point and at least one torch angle.

Abstract: Formerly, the ends of the light guides were provided with plug-in circular mounts. The fitting of the circular mounts is possible only in a special workshop. The object of the invention is to provide a plug-in connection which can be mounted at the place of application as well, without special auxiliary means. According to the invention, this object is achieved in that the end pieces (5, 6) exhibit a U-shaped profile in cross-section, the light guides (1, 2) are secured by means of grooved pressure pieces (11, 12) on the base of the profile so that their ends are free, and the free ends of the mutually impacting light guides (1, 2) are centred after the joining of two end pieces (5, 6) by means of a grooved centring piece (14). <IMAGE>

Abstract: This invention relates to a combination coal liquefaction-gasification process wherein hydrocarbonaceous mineral residue-containing slurry (58) from the liquefaction zone (22, 26) is recycled to the liquefaction zone and all non-recycled hydrocarbonaceous mineral residue-containing slurry (74) is passed to a gasification zone (76) for conversion to synthesis gas to supply hydrogen (92) for the liquefaction zone (22,26). It has now been discovered that in this process a surprisingly high reaction selectivity in favor of the desired distillate oil product is achieved by combining low liquefaction zone residence times and relatively high rates of recycle of mineral residue-containing slurry compared to feed coal rate. Under these conditions the yield of the desired distillate oil product can be increased to an unexpectedly high level while the yields of both higher and lower boiling products arc each being decreased and while hydrogen consumption is being reduced.

Abstract: Apparatus for manipulating a quantity of radioactive material between a stored position and a use position is provided with a coupling apparatus for separably connecting cable controls to a storage unit at the storage position, having a coupler componentfixed to the storage unit and a separable component (40,42) fitted to the control cable. The latter fits into an aperture in the fixed component (20,22,32,34,38), where it can be locked against removal. The fixed component (20,22,32,34,38) locks the radioactive material leader for safe storage when the control cable is disconnected. Connection of the control cable permits the operator to release the lock on the leader. The act of releasing that lock establishes an interlock which prevents removal of the separable component (40,42) from the fixed component (20,22,32,34,38).

Abstract: A printhead for a dot matrix impact printer comprises a stack of thin printing blades each including a flat spiral coil mounted in a rim which is in turn connected by flexible mounting arms to a mounting portion. Each blade has an arcuate printing arm extending from one side of the rim thereof and carrying a stylus, with the printing arms of adjacent blades being curved in opposite directions so as to provide therebetween a large separation area to prevent wicking ofinkfrom the styli to the coils of the blades. Each print arm carries a stabilizing member extending from the concave side thereof, with the stabilizing members of adjacent blades overlapping for cooperation to divide the separation area between said blades into inner and outer regions, the outer region serving to block particulate debris and isolate it from the inner regions thereby to prevent interference with the anti-wicking function of the inner regions.

Abstract: An oil burner which is intended to be used for the unpressurized feeding of even high-viscosity oils with a minimum throughput of not more than 1 kilogram per hour is provided with a burner head having an oil feed bore (7) which is surrounded by a guide jacket (1) for feeding air for combustion. At the nozzle-less outlet opening (6) of the oil feed bore (7) a swirler consisting of guide vanes (4) is inserted into the guide jacket (1) and causes the air for combustion to make so intensive a swirling movement that a negative pressure zone is formed downstream of the outlet opening (6) of the oil feed bore (7). A central mixing chamber (13) is formed in a guide member (10) disposed downstream of the outlet opening (6) of the oil feed bore (7). The oil discharged without pressurization by the outlet opening (6) of the oil feed bore (7) is broken up into individual drops by the air for combustion, and these drops are thereupon converted in the mixing chamber (13) into an oil mist by the action of the negative pressure zone. <IMAGE>

Abstract: A low phase noise signal source is disclosed which incorporates a voltage-controlled oscillator (VCO) (12) and a feedback network (16; 18) that, in effect, demodulates the VCO output signal and supplies negative feedback representative of the VCO signal noise to the VCO frequency control terminal (20). The feedback network (16; 18) includes a frequency discriminator (16) of the type wherein a time delay network (30) is connected to one input port of a phase detector (28), with the VCO output signal being supplied to the time delay network (30) and the second input port of the phase detector (28). A variable phase shifter (32), responsive to the signal supplied by the phase detector (28), is included in one of the phase detector input paths to cause a zero crossover of the frequency discriminator transfer characteristic to occur at the frequency to which the VCO is tuned. By establishing predetermined relationships between the transmission poles and zeroes of the feedback network, normal VCO tuning characteristics are preserved while simultaneously decreasing VCO phase noise. Various arrangements for operating the signal source over a wide band of output frequencies are disclosed, including a low-noise phase-locked loop frequency synthesizer.
