    Abstract: A method for a seismic survey, comprising: providing a plurality of basic waveforms; generating, for a first vibratory source, a first combined signal formed by sequencing the plurality of basic waveforms in a first order derived from a Costas array; and generating, for a second vibratory source, a second combined signal formed by sequencing the plurality of basic waveforms in a second order derived from said Costas array, wherein the second order is different from the first order.

    Abstract: A lubricating composition for use in the crankcase of an engine comprising (i) a base oil; (ii) one or more organo-molybdenum compounds at a level sufficient to provide from 50 to 500 ppmw of molybdenum; and (iii) from 0.2 wt% to 5 wt%, by weight of the lubricating composition, of one or more fatty diamine salt. The lubricating composition provides improvements in terms of reduced friction and wear, in addition to improved fuel economy performance.

    Abstract: The present invention relates to a reactor configuration comprising at least one electrically heated furnace which defines a space, with at least one reactor tube placed within the furnace space and said reactor tube having an exit and entrance outside of the reactor furnace, and wherein said furnace is further provided with - at least one electrical radiative heating element suitable for heating to high temperatures in the range of 400 to 1400 °C, said heating element being located inside said furnace in such a way that the heating element is in no direct contact with the at least one reactor tube; and; and - a number of inspection ports in the furnace wall such to be able to visually inspect the condition of the at least one reactor tube on each opposite side of said reactor tube during operation, the total number of inspection ports being sufficient to inspect all reactor tubes present in the furnace at their full length and circumference; and wherein the heating duty of the furnace is at least 3 MW. The process being electrically heated demands a heat- flux and temperature profile. In many applications the heat-flux is larger when the process enters the furnace whilst having a lower temperature. Towards the exit the heat-flux is lower whilst having higher temperature. The present invention can accommodate this requirement. The reactor is useful in many industrial scale high temperature gas conversion and heating technologies.

    Abstract: The present invention relates to a direct-coupled water electrolysis system and to a method of configuring a direct-coupled water electrolysis system comprising at least four components, wherein the first component is a PV-array which is directly connected to the second component which is an electrolyzer stack or multiple electrolyzer stacks, the third component is an electrolyzer system balance-of-plant, and the fourth component is an auxiliary power supply, the method comprising the steps of: a) providing a predetermined initial performance curve of the PV array; b) providing an average degradation rate of the PV array; c) calculating an anticipated performance curve of the PV array for a specific timeline by modifying the predetermined initial performance curve based on the average degradation rate; d) providing a predetermined initial performance curve of the electrolyzer stack or multiple electrolyzer stacks; e) providing an average degradation rate of the electrolyzer stack or multiple electrolyzer stacks; f) calculating an anticipated performance curve of the electrolyzer stack or multiple electrolyzer stacks for a specific timeline by modifying the predetermined initial performance curve based on the average degradation rate for each individual stack; g) configuring the electrolyzer stack or multiple electrolyzer stacks by matching the anticipated electrolyzer stack or multiple electrolyzer stacks performance curve with the anticipated PV array performance curve. The invention provides for operating a fully operational solar photovoltaic coupled electrolyser system at large scale up to multi-GW installed capacity, with the lowest possible content of power electronics and conversions to enable the lowest possible capital costs and optimised efficiency of the system.
