Abstract: Systems, methods, devices, and non-transitory computer-readable media for depth-based image tag generation are described. The disclosed technology may access images stored in an image repository. The images may comprise a first image. Using image processing techniques, a first object and a second object in the first image may be detected. Using machine-learning models, a first tag associated with the first object and a second tag associated with the second object may be identified. Using the machine-learning models, a first depth value associated with the first object and a second depth value associated with the second object may be determined. Based on the first depth value and the second depth value, a spatial relationship between the first object and the second object may be determined. Metadata associated with the first image may be generated. The metadata may indicate the spatial relationship between the first object and the second object.

Abstract: An apparatus for placement of seam tape to a roof or roof membrane. The apparatus comprises first and second sides spaced a distance apart, wherein each side includes a material axle opening and a pressure applicator orifice. The apparatus also comprises a removable pressure applicator having a first end and second end positioned in the pressure applicator orifices of the first and second sides. A support element may be operatively attached to the first and second sides, span the distance between the first and second sides, and positioned opposite the pressure applicator to support the apparatus. Additionally, a material axle may be positioned such that its ends are removably positioned in the material axle openings of the first and second sides. A closed front side may connect the first and second side, while an open stern may allow direct access to the pressure applicator, the support element, and the material axle.

Abstract: A process for the preparation of a desired chemical compound in a continuous reactor in which a part of the product stream exits the reactor and part of the product stream is recycled around the reactor in order to reduce the amount of buffer that would otherwise be required.

Abstract: Apparatus for generating a mist comprising a conduit having a mixing chamber and an exit; a transport nozzle in fluid communication with the said conduit, the transport nozzle being adapted to introduce a transport fluid into the mixing chamber; a working nozzle positioned adjacent the transport nozzle intermediate the transport nozzle and the exit, the working nozzle being adapted to introduce a working fluid into the mixing chamber; the transport and working nozzles having an angular orientation and internal geometry such that in use interaction of the transport fluid and working fluid in the mixing chamber causes the working fluid to atomise and form a dispersed vapour/droplet flow regime, which is discharged as a mist from the exit, the mist comprising working fluid droplets having a substantially uniform size.

Abstract: A process for the preparation of a compound of formula (I): wherein Ar represents an optionally substituted aromatic carbocycle or heterocycle, and R1 and R2 independently represent hydrogen, C1-10 alkyl, C(O)C1-10 alkyl or optionally substituted aryl provided that R1 and R2 are not both hydrogen which process comprises reacting together a compound of formula (II): Ar—X??(II) wherein Ar is as defined in relation to formula (I) and X represents a leaving group with a a compound of formula (III) wherein R1 and R2 are as defined in relation to formula (I) under aqueous conditions in the presence of a Pd (II) salt, a ligand and a Group I or Group II metal hydroxide base at a pH greater than 7. Compounds of formula (I) may be hydrolysed to the corresponding hydrazine.

Abstract: A process for the nitration of an aromatic or heteroaromatic compound with a nitrating agent comprising nitric acid or a mixture of nitric and sulphuric acids, characterised in that nitration is performed in a solvent comprising at least 50% v/v of a C.sub.1 -C.sub.6 alkyl ester of a C.sub.1 -C.sub.4 carboxylic acid. The process is of particular use for the nitration of diphenyl ethers to give compounds which are useful as herbicides or as intermediates in the synthesis of herbicides.
