Patent GB-2615305-A (GB)
Title: Crevice detection
Inventor: TANIS ADRIANO MAR HERNANDEZ
IPC: G06T7/00
Filed: 2022-01-28
Abstract: A method of detecting concave features, such as crevices, in the surface of an object to be cleaned comprising receiving point cloud data of the object, and identifying points having a local curvature below a predetermined curvature threshold. The local curvature may be determined to be concave when the average distance between the tangent plane defined by the normal to the point and k-nearest neighbours is positive. The curvature threshold may be determined based on one of: the geometry of the tool, the nature of the task to be completed, or the nature of the surface. A toolpath may be created based on the identified concave features by generating a representation of the surface. The surface representation may be based on a CAD representation of the object or a point cloud. An input generation tool may transmit the representation to a computer.

Patent GB-2607170-A (GB)
Title: Locking device
Inventor: JOHN MCLOUGHLIN
IPC: E05C9/02
Filed: 2020-09-04
Abstract: The locking device 1 has a deadbolt 104 within a casing 102. The deadbolt is movable between an advanced position wherein it protrudes from a front face of the casing and a retreated position. The locking device comprises: a link plate 130 which moves the deadbolt 104 to the advanced position. A deadbolt blocking member 110 which is moveable between a blocking position blocking the deadbolt in the advanced position and an unblocking position to allow the deadbolt 104 to move to the retreated position. An electrically driven actuator unit 120 moves the deadbolt blocking member. A control circuit controls the electrically driven actuator unit so that once the deadbolt 104 is moved to the advanced position, the deadbolt blocking member is moved to the blocking position by actuation of the electrically driven actuator unit. The blocker may be controlled as a result of a sensor which detects the position of the blocker. A detector is configured to detect whether the deadbolt blocking member is in the blocking position and the control cirtcuit stops actuation after moving the blocking member from the blocking to unblocking position.
Patent GB-2609079-A (GB)
Title: Building aperture
Inventor: PAUL EVANS
IPC: E06B7/26
Filed: 2022-05-20
Abstract: A building aperture frame 101 for fitting to a building aperture, and receiving a fitment e.g. a window, comprising a deflector 119 projecting outwardly such that in the event of a fire the deflector directs smoke and heated air escaping the building through the aperture away from the building such that the smoke and air is inhibited from rising an outer wall of the building. Preferably the deflector is angled upwardly and comprises a downward lip (123, fig 1) that induces an updraft in the smoke and heated gases. The frame may have a lower deflector 121 to deflect smoke away from the sill. The frame may comprise a two-part thermal barrier lining to inhibit smoke entering a wall cavity of the building and may be secured by an intumescent sealant. The deflector inhibits smoke re-entering an upper floor in a multi-storey building in the event of a fire.
Patent GB-2619769-A (GB)
Title: An optical device
Inventor: TAOFIQ PARAISO
IPC: H04B10/70
Filed: 2022-06-17
Abstract: This application is concerned with encoding information in the phase difference between a pair of coherent pulses. A coherent pair of pulses (220A, 220B), comprising an early pulse and a late pulse, is input to an optical device. A light routing element 206 of the device, such as a switch, selectively outputs either the early pulse or the late pulse to a first optical path 208A, and outputs the other pulse of the pair to the second optical path, 208B. A combiner 212 couples the first and second paths into a single output path. A phase controlling element 216, provided in the first optical path, imposes a pre-determined fixed phase difference between a light pulse routed through the first optical path and a light pulse routed through the second optical path. A first encoded state is obtained when the early pulse is passed through the first path and the late pulse is passed through the second path. A second encoded state is obtained when the allocation of pulses to paths is reversed. The first and second encoded states share the same basis. A third encoded state of another basis can be obtained by passing both pulses through the same path.
Patent GB-2620786-A (GB)
Title: Work coil for induction heated abatement apparatus
Inventor: ANDREW JAMES SEELEY
IPC: F23G7/06
Filed: 2022-07-22
Abstract: Abatement apparatus (100, Fig. 2) for treating an effluent stream from a semiconductor processing tool comprises a work coil 10 which inductively heats a porous susceptor 40 defining an abatement chamber. The coil is hollow and defines a conduit which is coupled with a source of reaction reagents. A surface 13 of the work coil has apertures 11 which convey reaction reagents from the conduit to supply the porous susceptor. The coil may surround the susceptor and may comprise turns 12 located along an axial length of the coil. The coil may be a helix or an axial stack of turns, and the distribution and direction of apertures may differ between different turns to provide a diffuse supply of reagent to the susceptor and to keep the apertures away from regions of high current. The coil may have a curved or polygonal cross section and the surface may be curved or planar and face the susceptor. A baffle (50, Fig. 3) may direct the flow of reagents in opposing circumferential directions. The work coil may also surround a porous insulator (30, Fig. 2) and may be enclosed in a housing (20, Fig. 2).

Patent GB-2611202-A (GB)
Title: Molar transfer device
Inventor: PETER M WILLIS
IPC: G01N31/12
Filed: 2021-06-03
Abstract: A device is provided for use in analytical instrumentation that provides continuous transfer of a known molar quantity of gas from a source having an unknown gas mixture and varying pressure. In addition to the upstream and downstream paths of typical flow control devices, the device has a midstream path to introduce a carrier gas at a known elevated pressure. The device has at least three equal-volume ballast vessels and a valve arrangement to cycle the ballasts through at least three states: fill, equilibrate, and empty. The ballasts fill with the upstream gas, pressurize and equilibrate at the midstream pressure, and empty to the downstream path. The cycle of each ballast is timed in phased relationship to the other ballasts to keep the flow relatively uninterrupted; as one fills, another equilibrates, and another empties.

Title: Natural language processing using an ontology-based concept embedding model
Inventor: BRENDAN BULL
IPC: G06F40/20
Filed: 2020-08-13
Abstract: A method 300, system, or program for a computer system to perform natural language processing (NLP) by generating a vector space model based on an ontology of concepts 310: training examples are extracted for concepts of a hierarchical ontology (200, fig.2A), wherein the training examples are based on neighbouring concepts 330; a plurality of vectors, each including one or more features, are initialized 340 and each vector corresponds to a concept, then a vector space model is generated by iteratively modifying the concept vectors to optimize a loss function 350; finally, natural language processing 360 is performed using the vector space model. Concepts can be assessed using cosine similarity between a concept vector and a mean vector of at least one of each of a parent concept and child concept. The vector space model may be a continuous bag of words model. The iterative optimisation can use both positive and negative training examples in order to optimise the loss function. The adjustment of vectors may also use a gradient descent algorithm.

Abstract: New anisotropic compounds with a cross-polarizing substituent have the formula (1)    <IMAGE>  (1)  The increase in  epsilon  ORTHOGONAL is achieved by the polarizing group X, preferably the cyano group or a halogen atom, which is not laterally on the ring, as with the known compounds, but is on the bridge, that is to say is part of the main bridge bonding rings A and B to one another. Ring A has the formula (1a) or (1b) given herein and is always cycloaliphatic, while ring B can be identical to ring A or is an aromatic ring of the formula (1c) or (1d) herein. R1 and R2 are identical or different end groups of the formula (1e) herein. The radical X on the bridge causes less widening of the molecule than a radical X on a ring, which provides comparatively higher clear points and moreover enables aromatic rings to be omitted from the anisotropic compounds.
