Abstract: A fluid dispenser having a pump mechanism that dispenses a dose of fluid when a movable pump member of the pump mechanism is moved between an extended position and a retracted position. A pump engagement body engages with the movable pump member for effecting movement of the movable pump member. A first cam surface and a second cam surface are connected to the pump engagement body, at least one of the first cam surface and the second cam surface comprising an adjustable cam surface whose location relative to the pump engagement body is selectively adjustable. A camming body engages with the first cam surface and the second cam surface to effect movement of the pump engagement body, and a dose adjustment mechanism allows the location of the adjustable cam surface relative to the pump engagement body to be selected.

Abstract: A compression apparatus includes at least one compression unit, a voltage applier, an anode end plate provided on an anode separator located at a first end in a direction of stacking, a cathode end plate provided on a cathode separator located at a second end in the direction of stacking, a first seal material that surrounds an outer periphery of the cathode, and a second seal material that surrounds an outer periphery of a first space in which to store compressed hydrogen, the first space being provided between the cathode end plate and the cathode separator located at the second end. The compression apparatus causes, by using the voltage applier to apply a voltage, protons taken out from an anode fluid that is supplied to the anode to move to the cathode via the electrolyte membrane and produces compressed hydrogen. An area of a region surrounded by the second seal material is larger than an area of a region surrounded by the first seal material.

The pump may have an input shaft connected to the driveshaft. The driving equipment may include an output shaft having an output flange connected to the driveshaft. The driving equipment may be configured to rotate the driveshaft to rotate the input shaft of the pump therewith. The vibration dampening assembly may include one or more flywheels operably connected to the input shaft and configured to rotate therewith.

Abstract: Systems and methods for supplying primary fuel and secondary fuel to an internal combustion engine may include supplying a first amount of the primary fuel and a second amount of the secondary fuel to the internal combustion engine. The system may include a first manifold to provide primary fuel to the internal combustion engine, and a primary valve associated with the first manifold to provide fluid flow between a primary fuel source and the internal combustion engine. A second manifold may provide secondary fuel to the internal combustion engine, and a fuel pump and/or a secondary valve may provide fluid flow between a secondary fuel source and the internal combustion engine. A controller may determine a total power load, the first amount of primary fuel, and the second amount of secondary fuel to supply to the internal combustion engine to meet the total power load.

Abstract: The present invention relates to a device exploiting magneto-hydrodynamics (MHD) for localized delivery of material into a target or extraction of material from a target. The device includes a frame (101) comprising a space (102) for conductive fluid and the material, at least one pair of electrodes (103A, 103B) facing each other, a source of electric current (105), a magnet (105), and an opening (106). The electric current and the magnetic field are synchronized so that the material can be moved from the volume between the electrodes through the opening towards the target or from the target through the opening towards the volume. According to the invention the volume is≤2000 mm3, in proviso that mean distance between tips of the electrodes is≤20 mm.

Abstract: The invention provides a liquid treatment apparatus such as a reverse osmosis apparatus wherein a portion of an inlet liquid permeates through a filter or a membrane e.g. to provide freshwater from saltwater. The apparatus comprises a pump which provides the necessary pressure of the liquid to drive the permeation process, and a recovery unit which transfers pressure of a residue quid to the inlet liquid. The pump and the recovery unit are driven at synchronous and variable speed to control the output and thereby e.g. to adjust for fouling of the filter or membrane. The invention further provides methods of controlling the synchronous speed, e.g. based on a pressure or based on the consumption of the produced liquid.
