A disposable pumping cassette in one embodiment includes a pump chamber; and a valve chamber in communication with the pump chamber, the valve chamber including an inlet and first and second outlets. A disposable pumping cassette in another embodiment includes a first valve chamber including an inlet and first and second outlets; and a second valve chamber including an inlet and an outlet, the second valve chamber openable to allow dialysis fluid to flow through one of the first and second outlets of the first valve chamber, through the outlet of the second valve chamber. A disposable pumping cassette in a further embodiment includes a valve chamber including a fluid inlet and first and second fluid outlets; and a flexible sheet openable to open and close only one of the first and second outlets.

A urine collection device (10) that is made up of a flexible, thermoplastic urine collection bag (20), which receives urine through a molded plastic inlet fitment (30) that is secured to an upper end of the bag 5 and discharges urine through a two-piece molded plastic valve fitment (40) at a lower end of the bag. The inlet fitment, which has no check valve therein, has a series of steps gradually reducing lateral extent as it extends longitudinally from the bag to a free end thereof, and each of the steps extends at a non-perpendicular angle to the longitudinal central axis of the inlet fitment. The bag is also free of any check or flutter valve. The outlet valve fitment has a fixed outer element (42) surrounding an inner element (44) that is rotatable with respect to the outer element to selectively open or close the outlet valve fitment to flow.

The hollow fiber membrane separator includes membeane assembly, control valve, pressure gauge, pump, air compressor, water tank, connecting pipes and other parts; and features that the upper mouth ofthe membrane assembly is connected via a back washing flow meter as well as a back washing regulating valve in one channel and a back washing automatic valve to the back washing pump pipe and the back washing pump via its inlet valve is connected to back washing water tank pipe in one channel and discharge valve pipe in the other channel; that the back water tank is connected to the filtering liquid outlet valve pipe via change-over valve and filtering liquid flow meter with the change-over valve being connected to circular water tank. The running process includes two steps in different cleaning states. The present invention makes it possible to realize ideal membrane separation and membrane cleaning.

A method and system for controlling an electrohydraulic braking system for a motor vehicle having an antilock braking control function and an electrically controllable pressure generating device having a cylinder-piston arrangement having a hydraulic pressure chamber and a piston displaceable by an electromechanical actuator so that a predetermined pressure can be set in the chamber, and having a number of hydraulically wheel brakes connected to the hydraulic pressure chamber by an electrically actuatable inlet valve and to a pressure medium reservoir by means of an electrically actuatable outlet valve. The cylinder-piston arrangement is actuated in case of antilock controlling at all wheel brake for setting an individual wheel target pressure at each wheel brake, such that the pressure in the hydraulic pressure chamber is set to the greatest wheel target pressure.

One aspect of the invention pertains to a device for mixing and dispensing fluids, which generally includes a housing; a mixing chamber having a first inlet for introducing a first fluid into the mixing chamber, a second inlet for introducing a second fluid into the mixing chamber, and an outlet through which fluid may exit the mixing chamber; and a valving rod received within the mixing chamber and movable between an open position, in which the first and second inlets are in fluid communication with the mixing chamber, a cleaning position, in which the valving rod substantially seals closed the first inlet but does not seal closed the second inlet, and a closed position, in which the valving rod substantially seals closed the first and second inlets.

An air outlet valve for use in an aircraft is adapted during normal operation of the aircraft as a component of a cabin pressure control system for adjusting a desired pressure level in an aircraft cabin to remove air from an interior of the aircraft into the environment around the aircraft. The air outlet valve is further adapted during emergency ventilation operation of the aircraft as a component of a system for emergency ventilation of the aircraft cabin to introduce air from the environment around the aircraft into the interior of the aircraft. The air outlet valve comprises a nose-side valve flap, which is pivotable about an axis and is adapted to open or close a nose-side portion of an air outlet valve aperture, and a tail-side valve flap, which is pivotable about an axis and is adapted to open or close a tail-side portion of the air outlet valve aperture. A portion of the tail-side valve flap that in the open state of the tail-side valve flap projects into an air stream flowing around an aircraft skin during cruising of the aircraft is greater than a portion of the nose-side valve flap that in the open state of the nose-side valve flap projects into the air stream flowing around the aircraft skin during cruising of the aircraft.

The fuel alcohol dewatering apparatus a rectification tower and a stripping tower connected serially, two parallel molecular sieves with valves in the inlets and the outlets, an overheater, a product cooler, a material preheater, a feeding pump, a waste water pump and a vacuum pump. The present invention has low power consumption, high energy recovering rate, no environmental pollution and high production efficiency.

The invention provides a firefighting extinguishment module which is large in power, long in an extinguishment water flow range and is high in system independence, and a control system. The system has high independence, and mains supply is not needed; and the module is easy to operate and can be started by one key. A radio remote control device is arranged in the module; and the remote control distance is more than 150 meters, and the distance between an operator and a fire source is more than 300 meters, so that the safety of the operator is effectively protected. The module comprises a box body, a diesel engine, a water collection device, a firefighting water pump, a pump outlet valve, a clutch, a vacuum air extractor, a fire plug, a fire monitor, a water cooling system and a hydraulic system; a water inlet of the firefighting water pump is connected with the water collection device; a water outlet is connected with a lower port of the fire monitor through the pump outlet valve; a rotation shaft of the firefighting water pump is connected with an output main shaft of the diesel engine through the clutch; an auxiliary output shaft of the diesel engine is connected with the hydraulic system through a transmission chain; the control end of a driving motor of a vacuum air pump is connected with a hydraulic oil system; and an air exhaust port of the vacuum air pump is communicated with the water collection device.
