Abstract: In chemical processes for cracking hydrocarbons, reactors are subject to coking. During the decoke process carburization of the metal substrate can occur, negatively impacting reactor life. Decokes are also costly due to down-time where costs are incurred without production of commercial products. Reducing the frequency of decokes provides an opportunity to reduce the financial impacts of downtimes. A start-up procedure is described herein that limits initial coke deposition, leading to a reduced tendency for carburization of the metal substrate, improving reactor life, and more importantly, extending reactor run length.

Abstract: The present invention includes a system for vaporizing at least two extracts, of which at least one contains at least one cannabinoid in a therapeutically or recreationally desirable ratio. The system includes a vaporizing apparatus with at least two distinct containers for vaporizable material. Cannabinoid concentrations included in the storage tanks could be identified and these cannabinoid concentrations may be compared to information that identifies user preferences that correspond to a mixture of materials from the respective storage tanks. The vaporizer may be configured to provide flows of materials to a heating element that vaporizes cannabinoids included in the mixture of materials when a person inhales vapors created at the vaporizer device according to a desired ratio. A computing device may monitor information received from a vaporizing device when assuring that a selected cannabinoid ratio does not exceed a limit found in a database.

Abstract: A circuit (3) for controlling a fluid impeller (6) in a fluid flow distribution system (1) to achieve a target fluid flow is disclosed. The circuit (3) is to output a speed signal representative of a speed value (N T ) of the fluid impeller (6) derived from a stored power consumption value (W i ) and fluid impeller speed value (N i ) pairs to achieve the target fluid flow. The circuit (3) is to receive a power signal representative of an input power consumption value (W) of the fluid impeller (6) at the speed value (N T ) to input a fluid to the fluid flow distribution system (1) and to compare the power consumption value (W) represented by the power signal input to the circuit (3) for the fluid impeller speed (N T ) with the stored power consumption value (W i ) and fluid impeller speed value (Ni) pairs to determine a least difference fluid impeller speed value (N L ) of the stored pair comprising a least difference between the input power consumption value (W) and the power consumption value (W i ). Responsive to determining the least difference fluid impeller speed value (N L ), the circuit (3) to output a speed signal representative of the least difference fluid impeller speed value (N L ).

Abstract: A beverage dispensing valve includes a housing defining a chamber with an inlet for receiving a fluid and an outlet for dispensing the fluid. A piston is located in the chamber and subjected to a fluid pressure exerted by the fluid received via the inlet. The piston is moved axially in the chamber by the fluid pressure such that the piston determines a flow characteristic of the fluid dispensed via the outlet. A plunger is received in the chamber, and the fluid pressure tends to move the piston towards the plunger. A spring tends to move the piston away from the plunger, against the fluid pressure. The plunger is axially registered in the chamber in discrete plunger positions, and each plunger position sets a discrete limit on axial movement of the piston thereby determining a predetermined flow characteristic of the fluid dispensed via the outlet.

Abstract: A system comprises a flow restrictor connected to a fluid flow path and located upstream from a chamber. The flow restrictor comprises an adjustable flow restriction aperture defined by the flow path region between a first element and a second element of the flow restrictor, and a drive unit configured to adjust the relative positions of the first element, second element or both to modify the fluid flow path across the aperture. The first or second element provides a curved boundary in the aperture flow path to form a converging region, a region of closest approach and a diverging region, within the flow path. Flow rate may be determined using a reference volume upstream from the flow restrictor.
