Title: Catalyst
Inventor: SHANWEN TAO
IPC: B01J23/755
Filed: 2018-04-24
Abstract: The invention relates to anion vacant lattices as a co-catalyst for augmenting the activity of existing Haber-Bosch process catalysts. The Haber-Bosch catalyst may be Fe, Co, Ni, Ru or combinations thereof. The anion vacant lattice may be doped to promote anion vacancies, and the anion vacancy may be an oxygen or nitrogen vacant lattice. The oxygen lattice can be CeO2, BaZrO3 or combinations thereof. The oxygen vacant lattice may be CeaMbO2-δ, where M has a valence less than 4, and “a” and “b” are independently in the range of 0.05 to 0.95, and together sum to 1, such as Ce0.8Sm0.2O2-δ. Alternatively, the oxygen lattice can have the formula BaZrxCeyYzO3-δ, such as BaZr0.1Ce0.7Y0.2O3-δ. Where the anion vacant lattice is nitrogen vacant, the lattice may be a zirconium nitride with the composition ZrN0.7. The anion vacant lattice may be present in the composition in the range of 5 to 20 wt% of the total composition. Further aspects relate to a catalyst cartridge for a Haber-process, use of the composition for production of ammonia, and a Haber-Bosch process for producing ammonia comprising exposing the composition to a mixture of nitrogen and hydrogen gas.

Title: Improvements in or relating to well abandonment and slot recovery
Inventor: MICHAEL WARDLEY
IPC: E21B29/00
Filed: 2018-05-02
Abstract: A single trip casing cutting and pulling assembly which selectively retrieves the seal assembly. This allows an integrity test to be performed on the same trip. The assembly includes a casing cutter 12, a casing spear 14, and a device 16 for retrieving a wear bushing and seal assembly, including a wear bushing 18 on a running tool 20. The running tool includes latching mechanisms to selectively latch the seal assembly to the modified wear bushing and running tool. When the modified wear bushing is landed in the wellhead housing, the running tool can pass through the modified wear bushing to allow cutting and pulling at any depth within the well, with the seal assembly remaining in the wellhead housing. The assembly can be used to remove the wear bushing and seal assembly, or alternatively can be tripped from the well without retrieving the bushing and seal assembly in the event of a failed integrity test.

Title: Reader with a balanced SAF free layer structure experiencing magnetic field gradient from a pair of adjacent perpendicular magnetic bits
Inventor: SUGUO HUO
IPC: G11B5/39
Filed: 2019-01-18
Abstract: A tunnelling magnetoresistive (TMR) read sensor 200 has a balanced synthetic antiferromagnetic (SAF) free layer structure 206 with RKKY second (or above) antiferromagnetic coupling peak through an Ru layer. A balanced SAF magnetic bias structure 204 is pinned by an anti-ferromagnetic (AFM) layer 202 to magnetically bias the SAF free layer structure. The sensor also has bottom ferromagnetic shield 113, top ferromagnetic shield 102, conductive cap 104, a thin non-magnetic layer 118 between the bias and free layer structures, a tunnel barrier 108, a pinned SAF structure 110 and a pinning AFM 112. The SAF free layer structure can be used to read out one bit stored information, but driven by a localized field gradient from a pair of adjacent perpendicular magnetic bits simultaneously that can reduce the reader free layer structure demagnetizing field for increasing the read signal amplitude and reduce the bit width to increase the magnetic recording storage aerial density due to experience of two magnetic bits while reading. The bias structure can give a dynamic bias with the rotation of free layer magnetisation to further increase reader signal.

Title: Method of reducing spatial extent of gradient coil current feeding connectors
Inventor: Geron Andre Bindseil
IPC: H01F5/04
Filed: 2019-05-18
Abstract: A magnetic resonance (MR) imaging system includes a gradient coil assembly comprising windings of coils arranged in a radial layer 206 and a set of electrical connectors 202, 204 at least partially embedded in the radial layer to reduce a radial extent or layer space occupied by the gradient coil assembly.

Similarly, cooling structures (428, 429, figures 4A to 4C) may also be embedded within the coil structure to reduce its radial size. The gradient coil assembly therefore allows a larger bore and/or a smaller overall radius of the MRI apparatus compared to a conventional gradient coil having connectors on the surface of the radial layer (figure 2B).

IPC: H05B47/195
Filed: 2020-03-16
Abstract: One aspect of this application (claim 17) relates to a light fixture 108b which modulates light to communicate status data 106 relating to the light fixture. The modulation of a visible light signal in this way is referred to as visible light communication (VLC) in the prior art. Another aspect (claim 11) relates to a wearable device 104 for receiving and decoding such a VLC signal. However, the first aspect (claim 1) relates to a monitoring device 104 for monitoring equipment in general 108a-108e. The equipment need not be a light fixture, but it must have an associated light source 102 such as an indicator LED. The light source is modulated to transmit status data relating to the equipment. The status data is used to determine a diagnosis for the equipment and provide a diagnostic action to a user through a user interface of the monitoring device such as a display. The monitoring device performs the preliminary step (530, Fig 1A) of monitoring a plurality of light sources (presumably associated with respective pieces of equipment) to determine which provides an “availability status indication”.
