Pressure swing adsorption (PSA) separation of a feed gas mixture is performed within an apparatus having typically a single prime mover powering a feed compressor for one or multiple rotary PSA modules in parallel, each module including a rotor with a large number of angularly spaced adsorber elements, with valve surfaces between the rotor and a stator so that individual adsorber elements are opened to compartments for staged pressurization and blowdown, with thermally boosted energy recovery from staged expansion of countercurrent blowdown and light reflux gases, and a plurality of adsorber elements opened at any instant to each compartment so that each compressor and expander stage operates under substantially steady conditions of flow and pressure.

The magnitude of torque which can be transmitted by a bypass clutch between the housing and the turbine of a torque converter between a prime mover, such as an engine, and an automatic transmission in the power train of a motor vehicle is selectively regulatable by a computerized regulating unit. The regulation involves the transmission of torque by the clutch in dependency upon the magnitude of the torque being transmitted by the output element of the engine and ascertaining as well as adaptively applying to the clutch a variable force so that the clutch can transmit a predetermined torque. This entails automatic selection of a minimum slip between a torque receiving and a torque transmitting part of the power train. Compensation, particularly long-range compensation, is carried out for the existence of possible differences between the predetermined and actual torques being transmitted by the clutch.

System and method for the combination of a flywheel and motor/generator inside a wheel hub for hybrid vehicle propulsion. The flywheel and motor/generator are connected by a planetary gear system, in which a first port is connected to the flywheel, a second port is connected to the wheel hub, and a third port is connected to a motor/generator. An additional motor/generator may be used at one of the first port and second port. The system may be used in an electric-kinetic hybrid mode, or in a fuel-kinetic hybrid mode, when used in a vehicle having an internal combustion engine as the prime mover. Efficiency of energy storage and release is significantly improved in comparison to prior art.

A dual system for overall engine emissions control, including prevention of excessive formation of nitrogen oxides and carbon compounds 1) by cooling and humidifying intake air and 2) by restructuring and modifying hydrocarbon fuels, resulting in a more complete combustion, a significant reduction of the latent heat of combustion and increased combustion potency. The invention utilizes one or more ultrasonic devices to create an aqueous vapor from an ultra-pure water supply, said vapor varying in quantity according to engine size and load, having electronic sensors and controls for precision switching, metering and delivery. Simultaneously, while humidifying the intake air, the hydrocarbon fuel is passed from a fuel supply through a catalytic reactor to restructure the hydrocarbon molecules into a more homogeneous, more combustible and cleaner-burning fuel. Thus equipped, said internal combustion engine can be run as a fuel conserving, low emissions prime mover.

A foldable implement frame is foldable about multiple axes to provide a compactly folded implement. The implement is foldable from a wide, field working position to a relatively narrow position for transport between fields, along roadways, and through field gates or storage doors. The frame is generally comprised of a center frame section that may be hitched to a prime mover, a pair of inner frame sections, and a pair of outer frame sections. The outer frame sections may be folded about their connections to the inner frame sections, and the inner frame sections are foldable about their connections to the central frame section. The central frame section may be rotated to rotate the inner and outer frame sections forward to an upright position, and the inner and outer frame sections may then be folded forward to fold the frame into a narrow position for transport and/or storage.

The invention relates to a novel rotation driving system for a mixing drum of a concrete mixing transport vehicle. In the system, two prime movers, two hydraulic main pumps, an oil supply pump and a hydraulic motor form a hydraulic closed loop together with a hydraulic valve block with the functions of relatively completing oil supply, cooling and safe buffering; the delivery volumes of the two hydraulic main pumps are different; and the low-delivery volume hydraulic main pump is used for separately realizing slow and constant mixing action of the mixing drum, and the high-delivery volume hydraulic main pump is used for rotating the mixing drum along positive and negative directions at a high speed during feeding and discharging when separately operated or combined with the low-delivery volume hydraulic main pump. The system aims to solve the problems of the influence on the concrete uniformity and the influence on the driving dynamic performance and driving safety performance which are caused by driving a roller to rotate by separately using a chassis engine under different working conditions and different road conditions in the mixing drum, fuel waste caused by the long-term operation of the high-power chassis engine at low-efficiency points and the hydraulic shock generated during the switching of the mixing drum under different working conditions.

The power train of a motor vehicle has an automated clutch which can transmit torque from a prime mover to a transmission in response to signals from an electronic control unit. The latter causes the clutch to transmit a constant torque during a first interval, to thereupon transmit a gently varying torque during a second interval if the operator of the motor vehicle fails to carry out certain necessary operations prior to elapse of the first interval, and to thereafter transmit a pronouncedly varying torque during a third interval if no remedial undertakings were completed during the second interval. The third interval is cut short if the engine tends to choke, and the full or shortened third interval can be followed by a fourth interval corresponding to the first interval or by a further interval corresponding to the second interval.

In varying embodiments, the fault tolerant linear actuator of the present invention is a new and improved linear actuator with fault tolerance and positional control that may incorporate velocity summing, force summing, or a combination of the two. In one embodiment, the invention offers a velocity summing arrangement with a differential gear between two prime movers driving a cage, which then drives a linear spindle screw transmission. Other embodiments feature two prime movers driving separate linear spindle screw transmissions, one internal and one external, in a totally concentric and compact integrated module.

An increase in angular acceleration α of a rotating shaft of a motor, which outputs a torque to a drive shaft linked to drive wheels, may cause a skid on the drive wheels. In response to detection of a skid, the control procedure of the invention sets a maximum torque Tmax according to a preset map representing a relation between the angular acceleration α and the maximum torque Tmax, and restricts an output torque level to the drive shaft. The map is set to decrease the maximum torque Tmax with an in crease in angular acceleration α. The restricted output torque level is restored at a zero cross timing of the angular acceleration α after a negative peak in the course of convergence of the skid. This arrangement makes the direction of the torque restored from the torque restriction identical with the direction of the angular acceleration, thus effectively reducing torsions of the drive shaft and thereby preventing potential torsional vibrations of the drive shaft.

The invention, which belongs to the field of the power system and automation technology thereof, provides a method for locating prime motor disturbance source triggering forced power oscillation.
