Marine vessel control system

A marine vessel control system includes a primary marine propulsory mechanism attached to the vessel and an intelligent vessel control system. Also included is an attitude sensor linked with the intelligent vessel control system. An actuating system responding to an output of the intelligent vessel control system is linked with the primary marine propulsory mechanism for adjusting a trust vector of the e primary marine propulsory mechanism.

Method of rendering a radioactive and aqueous heat transfer liquid in a nuclear reactor to a reduced radwaste quantitative state and returning the remaining waste water volumes to an environmental release point for liquid effluents

ActiveUS20100020915A1Maximize boron controlMeet requirementSolid sorbent liquid separationWater/sewage treatment by ion-exchangeIonIon exchange
Environmentally protective Method of treating an aqueous radioactive fluid (AF) in a nuclear reactor cycle or radwaste system to selectively capture or remove radioactive isotopes in a reduced quantitative package to minimize radwaste generated and revitalize neutron absorption capacity of nuclear reactor coolant by separately carrying away boron constituents, when B10 is later added. The method includes: demineralizing the (AF) by rough ion exchange and lowering the pH of salts, boron and non- radioactive substances so that the boron can later pass through an RO; polishing by reverse osmosis; dividing the (AF) into a permeate liquid volume and a reject liquid volume, each having certain characteristics; recycling the reject liquid volume back into demineralizing step for removing generally most of the radioactive isotopes to generate a demineralizer effluent; and conveying the permeate liquid volume to the outside ambient environmental release point for liquid effluents of the (AF); dividing the demineralizer effluent into a further permeate liquid volume and a further reject liquid volume having certain characteristics; and conveying the further permeate liquid volume to the outside ambient environmental release point of the invention.

ActiveCN109433830AMaximize controlReal-time online adjustmentProfile control deviceLoop controlOrder reduction
The invention discloses a cold-rolled sheet shape closed-loop control method and system. The cold-rolled sheet shape closed-loop control method comprises the steps: evaluation functions synergistically controlled by cold-rolled sheet shape executing mechanisms are built according to cold-rolled sheet shape regulating and controlling efficacy coefficients; k-time solution vectors of the executing mechanisms are determined according to the evaluation functions; whether the k-time solution vectors are within feasible regions of the cold-rolled sheet shape executing mechanisms or not is judged, and if yes, the k-time optimal regulating variables are obtained; if not, evaluation functions harmoniously controlled by the cold-rolled sheet shape are determined, and gradient informationof the evaluation functions and the regulating directions of the cold-rolled sheet shape executing mechanisms are determined according to parameters of the cold-rolled sheet shape executing mechanisms; final values of the regulating variables of the executing mechanisms are determined according to the gradient information and the regulating directions; the evaluation functions are subjected to order reduction according to the final values, evaluation functions subjected to order reduction are obtained, and (k+1)-time solution vectors are determined, wherein the relation of k=k+1 is made to be met; and the cold-rolled sheet shape is adjusted according to the k-time optimal regulating variables of all the cold-rolled sheet shape executing mechanisms. According to the cold-rolled sheet shape closed-loop control method and system, the sheet shape regulating speed can be increased.

Brake caliper with brake pad timing and retraction controller

A brake caliper is provided with a timing and retraction controller that that adjusts brake timing, eliminates parasitic brake losses and dampens out-of-plane vibration between the brake pad and rotor. The brake caliper includes a housing disposed over a brake rotor; first and second opposing brake pads extendably and retractably mounted on opposite sides of the caliper housing, brake pistons that extend and retract the brake pads into and out of frictional engagement with the rotor, and brake pad timing and retraction controllers disposed on opposite sides of the caliper housing. Each controller includes a Belleville spring or other resilient member with a short compression travel limited to between about 1.50 mm and 0.025 mm. The short stroke Belleville spring of each controller applies a hold-off force against the extension force of the brake pistons that slightly delays brake pad extension and slightly reduces brake pad clamping force against the rotor, thereby advantageously providing a front wheel braking bias when applied to the rear wheels of a vehicle. The restorative force applied by the short stroke Belleville forcefully and uniformly retracts the brake pad from the rotor, eliminating parasitic brake losses, and dampening out-of-plane vibration between the brake pad and rotor.

Dynamic control of selective non-catalytic reduction system for semi-batch-fed stoker-based municipal solid waste combustion

The present invention controls reagent flow levels in a selective non-catalytic reduction (SNCR) system by more accurately predicting Nitrogen Oxides (NOx) production with a municipal waste combustor. In one embodiment, the reagent levels correspond with measured furnace temperatures. The reagent levels may have a baseline level from prior measured NOx that is then modified according to temperatures measurements. A slow controller may use NOx measurements over an extended period to define a base regent level, and a fast controller may use additional information such as the furnace temperature to modify the base regent level. The fast controller may further receive two additional signals that are added individually or together to maximize NOx control while minimizing ammonia slip from the reagent. The two signals are a feed-forward signal from the combustion controller and a feedback signal from an ammonia analyzer downstream of the combustion zone.
