Title: High efficiency water treatment process
Inventor: ALEX DRAK
IPC: C02F103/08
Filed: 2019-12-10
Abstract: A process for treating water by passing feed water from an input chamber (2, Fig. 2) through a semi-permeable membrane (8, Fig. 1) to produce product water and brine and removing sparingly soluble salts in the brine by passing it through a salt removal unit (20, Fig. 1), e.g. a fluidised bed crystalliser containing seed particles. The brine is subject to a series of recirculation steps comprising: (i) returning the brine to the input chamber to pass the brine through the semi-permeable membrane to re-concentrate the brine; and (ii) performing a series of step-by-step recirculation steps for continued re-concentration of the brine and crystallisation of low soluble salts to increase the recovery by membrane separation. The saturation indexes of one or more low soluble salts are maintained within a controlled crystallisation zone: calcium carbonate logarithm of saturation index (Log SI) of 0.5-2.0; calcium sulfate saturation index (SI) of 100%-400%; silica SI of 100%-220%; barium sulfate SI of 100%-5000%; and calcium fluoride SI of 100%-400%. The controlled crystallisation zone is below an unstable and metastable zone and above a stable zone and comprises slightly saturated conditions wherein salt crystals grow only on a low energy surface and cannot nucleate.

Title: Electrode active material grown by plasma-enhanced chemical vapour deposition
Inventor: SHASHI PAUL
IPC: H01M4/38
Filed: 2020-06-09
Abstract: A method of growing an electrode active material uses plasma-enhanced chemical vapour deposition (PECVD). The electrode active material is grown by providing a seeding layer (31, Figure 3) comprising a first precursor for providing charge carriers to a reactor 41 and exposing the seeding layer to a plasma phase of a second precursor at a temperature above a cracking temperature of the seeding layer. The first precursor may comprise an alkali metal, such as lithium, sodium or potassium, which may be bound in a coordination complex with an organic ligand. Suitable materials include lithium acetate and sodium acetate. The second precursor may comprise silicon or germanium and can be silane, silylene, trichlorosilane, germane or germylene, for example. The seeding layer may comprise a further precursor comprising Tin, such as Tin (II) Acetylacetonate. The grown electrode active material comprises an alloy of the charge carriers and elements from the second precursor, for example a lithium-silicon alloy or lithium-silicon-tin alloy. When the electrode active material is in use, the charge carriers can be extracted from the electrode active material in the presence of an electric field, leaving vacancies for later insertion of the charge carriers.

Title: Maintaining inflatable product pressure
Inventor: SCOTT ABBOTT
IPC: G05D16/00
Filed: 2020-10-28
Abstract: A method of maintaining the internal pressure of an inflatable product 11, such as a bouncy castle or bounce house. The method utilises a control apparatus 10. An air flow generator 12, such as a blower or fan, is operated by a motor 13 and supplies a flow of air internally to a connected inflatable product 11. A sensor arrangement indirectly monitors the internal pressure of the connected inflatable product 11 by monitoring the torque and/or speed of the motor 13. A motor controller 21 adjusts the speed of the motor 13 depending upon the monitored pressure. Preferably, parameters of the motor such as voltage, current and/or motor speed are directly measured, these parameters are then used to calculate the torque of the motor. Ideally, the user may select a low power mode or a high power mode which causes the product to be inflated to a low or a high pressure respectively. Advantageously, the control apparatus may include a wind speed sensor / anemometer 22 wherein an alert is generated if the measured windspeed exceeds a threshold safety value. The control apparatus may also include other safety sensors that detect a failure of air flow, a power supply failure and the motor/controller temperature.

Abstract: In an approach for real-time opportunity discovery for productivity enhancement of a production process, a processor extracts a set of features from time series data, through autoencoding using a neural network, based on non-control variables for the time series data. A processor identifies one or more operational modes based on the extracted features including a dimensional reduction with a representation learning from the time series data. A processor identifies a neighborhood of a current operational state based on the extracted features. A processor compares the current operational state to historical operational states based on the time series data at the same operational mode. A processor discovers an operational opportunity based on the comparison of the current operational state to the historical operational states using the neighborhood. A processor identifies control variables in the same mode which variables are relevant to the current operational state.
