A wheel driven utility vehicle includes a frame and two small volume high speed alternating current electric motors arranged side by side for driving the vehicle. Alternatively high speed direct current, hydraulic or pneumatic direct current motors may be used with suitable controls. Each motor has an output shaft which drives an offset planetary gear reducer. Each offset planetary gear reducer is affixed to the electric motor and includes an output carrier interconnected with an output shaft. Each output shaft includes first and second chain drive sprockets which drive chains interconnected with shafts driving the front and rear wheels respectively. Each offset planetary gear reducer enables use of space saving high speed relatively low-torque alternating current electric motors with attendant large speed reductions. Gear reduction enables the production of sufficient torque at the wheels of the vehicle. Applications in addition to utility vehicles are also specifically contemplated.

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.

A processing device (10) includes a receiver for receiving a data file and an associated data file policy and for receiving an application and an associated application policy, storage means for storing the received policies, a policy evaluation module (131) for evaluating policies and a policy enforcement module (135) for enforcing the evaluation specified by the policy evaluation module (131). The device (10) is operable, in response to receiving a request for the application to open the data file, to cause the policy evaluation module (131) to evaluate the data file policy associated with the data file together with the application policy associated with the application and to cause the application to open the data file or not in dependence upon the evaluation.

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.

A direct engagement drive system [108] for a tripper conveyor system is disclosed. The drive system [108] comprises lead [140′] and follow [140″] cogwheels, each driven by a programmable logic controller [108q] and variable frequency drive-controlled electric motor [108a]. The torque applied to each of the lead [140] and follow [140] cogwheels varies as a function of loading experienced by the cogwheels [140] and as a function of the location of the cogwheels [140] relative to a gap [159] or other discontinuity in a cog rail [150] provided on a conveyor [110]. A process for moving a tripper [100] along a conveyor [110] is also disclosed. Other mobile conveying device such as mobile hoppers, maintenance vehicles, stacking machines, conveying devices, or cranes may employ the drive systems [108] shown and described.

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.
