Abstract: A process for the manufacture of a useful product from synthesis gas having a desired hydrogen to carbon monoxide molar ratio comprises gasifying a first carbonaceous feedstock comprising waste materials and/or biomass in a gasification zone to produce a first synthesis gas; optionally partially oxidising the first synthesis gas in a partial oxidation zone to generate oxidised synthesis gas; reforming a second carbonaceous feedstock to produce a second synthesis gas, the second synthesis gas having a different hydrogen to carbon ratio from that of the first raw synthesis gas; combining at least a portion of the first synthesis gas and at least a portion of the second synthesis gas in an amount to achieve the desired hydrogen to carbon molar ratio and to generate a combined synthesis gas and subjecting at least part of the combined synthesis gas to a conversion process effective to produce the useful product.

Abstract: The present invention provides dry powder inhaler (DPI) devices (100) for dispensing dry powder and methods for using the same. The DPI devices feature vortex mechanisms for directing air in a turbulent manner sufficient to entrain an amount of a dry powder dose for delivery into a user's lungs. The DPI devices feature replaceable dry powder cartridges (200). The DPI devices also feature a retractable configuration for storage and for accidental dispensing of dry powder. The DPI devices dispense dry powder in controlled dosages.

Abstract: A process for the manufacture of one or more useful products comprises: gasifying a carbonaceous feedstock comprising waste materials and/or biomass in a gasification zone to generate a raw synthesis gas; supplying at least a portion of the raw synthesis gas to a clean-up zone to remove contaminants and provide a clean synthesis gas; supplying the clean synthesis gas to a first further reaction train to generate at least one first useful product and a tailgas; and diverting selectively on demand a portion of at least one of the carbonaceous feedstock, the clean synthesis gas, the tailgas and the light gas fraction to heat or power generation within the process, in response to external factors to control the carbon intensity of the overall process and enable GHG emission savings.

Abstract: The present invention provides a process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, the process comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; sequentially removing ammoniacal, sulphurous and carbon dioxide impurities from the raw synthesis gas to form desulphurised gas and recovering carbon dioxide in substantially pure form; converting at least a portion of the desulphurised synthesis gas to a useful product. Despite having selected a more energy intensive sub-process i.e. physical absorption for removal of acid gas impurities, the overall power requirement of the facility is lower on account of lower steam requirements and thereby leading to a decrease in the carbon intensity score for the facility.

Abstract: Disclosed herein is a catheter pump that includes an expandable cannula and an impeller system. The expandable cannula defines a blood flow channel and includes an impeller blade zone, an inlet zone, and an outlet zone. The catheter pump further includes an impeller system including an impeller body, the impeller system movable relative to the expandable cannula along a longitudinal axis of the catheter pump. The catheter pump is selectively transitionable between a separated configuration in which the impeller body is axially spaced from the expandable cannula along the longitudinal axis, and an operational configuration in which the impeller body is positioned within the impeller blade zone of the expandable cannula.

Abstract: A filter element assembly includes a filter body and an auxiliary filter. The filter body includes a sidewall around a hollow core. Further the filter body and auxiliary filter are both received and held on a support including a base and a cage.

Abstract: The present invention provides in part dry powder inhaler (DPI) devices for dispensing dry powder and methods for using the same. The DPI devices feature exchangeable cartridges having drum mechanisms that prepare metered doses of dry powder, and are able to direct air in a turbulent manner sufficient to entrain and deagglomerate a dose of dry powder for delivery into a user's lungs. The DPI devices feature a reservoir of dry powder advanced by a plunger, as well as a gauge that advances with the plunger to indicate the amount of dry powder remaining in the reservoir.

Abstract: Service tracking using beacons may include receiving, at a computing device including a processor, a plurality of beacon identifiers from a plurality of beacons. Each of the plurality of beacon identifiers may be associated with a unique beacon that may be located at a fixed location on a property. The plurality of beacons may form a matrix of beacons. Once the beacon identifiers are received, the computing device may determine a location of the computing device within the matrix of beacons. The location may include a proximity to one of the plurality of beacons. Once the location of the computing device is determined transmit a service request that may be associated with a service selection may be transmitted to a remote computing device. The service request may include service data for performing the service and the location of the computing device within the matrix of beacon.
