Title: Process and method for refining lithium carbonate starting from an impure lithium chloride solution
Inventor: HEIN JASON ELLIS
IPC: C01D15/00
Filed: 2020-12-09
Abstract: A method for refining lithium from a crude brine includes charging a crude brine into a feeder tank held at a temperature T1 and containing a sufficient carbonate source to precipitate all carbonate-forming solids in the crude brine to form a precipitate mixture and a crystal free supernatant; pumping the crystal free supernatant from the feeder tank to a first crystallization reactor that is held at a temperature T2 to crystallize a lithium carbonate salt out of the crystal free supernatant; wherein the temperature T1 is lower than the temperature T2; and controlling a flow rate to maintain a steady state concentration of the lithium carbonate salt in the solution phase of the crystallization reactor.

Title: Three resin reactors in series peptide synthesizer
Inventor: JOHNSON MARTIN D
IPC: C07K1/04
Filed: 2021-01-29
Abstract: A Solid Phase Peptide Synthesis (SPPS) device and method of using the same for manufacturing peptides is taught herein. The system comprises at least two reactors, each reactor including a quantity of SPPS resin. The reactors are positioned in series. A de-protecting agent is added to the first reactor and then transferred to the second and third reactors, in series, thereby operating to de-protect the protected N-group. Wash solvent is added to the first reactor and then transferred to the second and this operation repeated several times. Likewise, an amino acid activated ester solution is added, in series, to the first, second and third reactors, thereby operating to couple the amino acid to the de-protected N-group. Wash solvent is added to the first reactor and then transferred to the second and this operation repeated several times prior to the next cycle. The use of the reactors in series reduces the overall solvent required. Online LCMS is also used to monitor progress and identity of reactions happening within the solid phase resin particles.

Title: Vertical continuous multiphase reactor for the clean production of hydrocarbons and energy and thermochemical method carried out
Inventor: GUTIERREZ FONSECA JAIME EDUARDO
IPC: F23G7/10
Filed: 2021-04-14
Abstract: Disclosed is a reactor and method for thermochemically degrading wet biomass without the need for prior drying, in particular microalga-rich substrates. The invention provides a vertical continuous multiphase reactor (VCMR) that simultaneously, progressively and continuously carries out the steps of evaporation, pyrolysis, gasification and combustion, in separate chambers, using indirect heating. The reactor operates at pressures below atmospheric pressure to increase thermal and productive efficiency, using a fraction of the same products as fuel to achieve thermal self-sufficiency. A system for instant evaporation at low temperature by means of adiabatic expansion is used. The reactor has high efficiency and high yield, requiring minimum space, and can be movable. The products obtained from the reactor are synthesis gas, biocarbon and bio-oils, with uses in energy, agriculture, cosmetics, health and construction. The invention also provides a method for obtaining hydrocarbons and energy from high-moisture biomass, wherein the steps are carried out continuously and the method does not need to be interrupted to add new wet biomass for conversion.

Title: Detecting contamination or feature mixing within harvest polygons at a vector level
Inventor: WERNER FLETCHER
IPC: A01B79/00
Filed: 2021-09-02
Abstract: Systems and methods for determining a degree or rate of error for treatments at a field are disclosed herein. In some embodiments, a system receives first data corresponding to a first agronomic treatment at a field and second data corresponding to a second agronomic treatment at the field. The system uses the first and second data to determine differences and overlaps between characteristics of the first and second data to quantify an error rate at individual subsets of the field. Based on the quantified error rate, a number of metrics and yield data may be interpreted differently or modified to fit the result of the quantified error rate. The system uses the quantified error rate to predict the effectiveness of treatments, modify the rate of experienced yields at a field, and recommend real-time and subsequent corrective actions to take at the field.

Title: Calcul de peripherie a faible puissance avec reseaux neuronaux optiques par diffusion par ponderation par multiplexage par repartition en longueur d'onde
Inventor: HAMERLY RYAN
IPC: H04B10/80
Filed: 2021-07-29
Abstract: NetCast est une architecture de réseau neuronal optique qui contourne des contraintes sur une inférence de réseau neuronal profond (DNN) au niveau de la périphérie. De nombreux DNN ont des matrices de pondération trop grandes pour s'exécuter sur des processeurs de périphérie, conduisant à des limitations sur l'inférence de DNN au niveau de la périphérie ou à des goulots d'étranglement de bande passante entre la périphérie et le serveur qui héberge le DNN. Avec NetCast, un serveur de pondération stocke la matrice de pondération de DNN dans une mémoire locale, module les pondérations sur différents canaux spectraux d'un support optique et distribue les pondérations à un ou plusieurs clients par l'intermédiaire de liaisons optiques. Chaque client stocke les activations, ou des entrées de couche, pour le DNN et calcule le produit vectoriel de matrice de ces activations avec les pondérations provenant du serveur de pondération dans le domaine optique. Cette multiplication peut être effectuée de manière cohérente par interférence des pondérations multiplexées spectralement avec des activations multiplexées spectralement ou de manière incohérente par modulation du signal de pondération provenant du serveur de pondération avec les activations.
