Pyloric valve corking devices and methods are described herein. The devices generally include an occluding member which expands from a first configuration to a larger second configuration and a bridging member extending from the occluding member. The bridging member has a length which passes at least partially through the gastric opening such that the occluding member obstructs the gastric opening, and wherein the length permits the occluding member to intermittently move relative to the gastric opening. A second occluding member may be attached to the distal end of the bridging member. The reduction in flow of gastric contents into the duodenum can be tightly regulated using a pump or valve. Otherwise, the flow can be passively regulated with the occluding device.

An adjustable drainage system for regulating cerebrospinal fluid flow in a hydrocephalus patient where the drainage rate is adjusted in response to ventricular volume variations in the patient. The system includes an adjustable valve and a volume sensor that can be periodically energized with an external system controller device by the patient or attending physician to determine when, or if, a change in the ventricular volume has occurred. The system enables the user to adjust the valve's resistance in response to changes in the ventricular volume using the controller device so that a target ventricular volume can be achieved. Also provided is a method of continuously draining cerebrospinal fluid from the cranial cavity of the patient using the system of the present invention.

An apparatus, system, and method for precise dispensing of a desire volume of liquid. The present system allows incorporation of brewer control and a faucet in an accurate volume dispensing system. The dispensing apparatus is used in combination with a beverage maker and includes a liquid reservoir with a level sensor associated therewith for sensing a liquid level in the reservoir. An inlet tube communicates with the reservoir and a constant line pressure source. An inlet valve positioned along the inlet tube is controlled by a controller. The controller also controls an outlet valve communicating with an outlet tube extending from the liquid reservoir. The controller operates the outlet valve to remain open for a time period which is the longer of an initial set time period and one or more refill periods. The controller may also controllably adjust the outlet time period by monitoring for reductions in the time the inlet valve remains open.

The power plant disclosed is an engine that derives its usefulness in the pursuit of energy generation by utilizing hydrostatic pressure differentials found or created in various liquids, gases or solutions, such as but not limited to water and air. It is generally provided as a two-stroke piston cycle power generating system, wherein the actions of the pistons perform work or replenish working fluid from a lower head to a higher head, and can be utilized to generate power, pump fluids, or perform work, for example. Multiple power generating systems are interconnected to provide continuous and constant power generation through a penstock and turbine system.

The pressure drop associated with the coolant flow in the coolant transition regions of a typical high power density, solid polymer electrolyte fuel cell stack can be significant. This pressure drop can be reduced by enlarging the height of the coolant ducts in this region of the associated flow field plate so that the ducts extend beyond the plane of the plate. The height change can be accommodated by offsetting the ducts in adjacent cells in the stack and by employing non planar MEAs in this region. By reducing the pressure drop, improved coolant flow sharing is obtained.

The invention relates to non deep-fried instant noodles and a preparation method thereof. The non deep-fried instant noodles adopt a one-piece structure that an upper layer is a seasoning block and a lower layer is a cake.
