A static bilge pump has an inlet tube, a body and one or more eductors. It may be attached to the back of a boat using bolts, or other means such that the inlet tube may be inserted into the drain at the bottom of the bilge of a boat. A siphon tube connected to the inlet tube hasn't ends that may be placed at the bottom of the bilge or moved about by an operator. The eductor's are streamlined to minimize drag and prevent blockage by debris and flotsam. Buttresses may extends between the body and the doctors to improve stability.

The present invention relates to a microfluidic assay system and associated reading device, as well as the individual components themselves. The present invention also relates to methods of conducting assays, using a disposable system and associated reading device, as well as kits for conducting assays.

A fluid pump for moving fluid from a first reservoir to a second reservoir is described. The fluid pump comprises a first reservoir containing a fluid, a second reservoir for receiving the fluid, at least one chamber subject to alternating high and low pressure, and an inlet valving device modulating or switching pressures to which the at least one chamber is exposed, causing the fluid to flow into the at least one chamber from the first reservoir when the at least one chamber is exposed to low pressure and causing the fluid to flow out of the at least one chamber into the second reservoir when the chamber is exposed to high pressure.

A buoy assembly for use with a pumping system to pump liquid and debris from a flooded shaft or well or any such structure with appreciable depth is provided. The buoy assembly includes a proximal tube that can couple to an end of a hose coupled at an opposite end to the pumping system. A buoy is coupled to the proximal tube that provides the buoy assembly with buoyancy that allows the buoy assembly to float on the liquid in the shaft. The buoy can have one or more aeration ports that can be selectively opened (by removing a plug therefrom) to allow airflow therethrough into the buoy. The buoy assembly also has an adapter socket with feet that define vents therebetween to allow passage of debris via the vents into the buoy. Flow of air into the buoy via the aeration ports facilitates lift of liquid and debris through the conduit during a pumping operation.

A gas compression system includes a first hollow cylinder with a top and bottom, a gas source for relatively uncompressed gas entering through the top, and a gas collector tank connected by an outlet line. The gas compression system includes a liquid holding tank with liquid connected to the first cylinder bottom and a pump linking the liquid holding tank to the first cylinder bottom. An actuation system controls the liquid and gas input/output, and a controller manages the pump to move liquid at a higher pressure than the relatively uncompressed gas. This vertical movement of liquid compresses the gas, and the controller releases the compressed gas into the collector tank when it exceeds a predetermined pressure. A gas compression system with two hollow cylinders is also provided.

A liquid supply system includes a base seat, a liquid storage apparatus, and a pressure supply module. The liquid storage apparatus is disposed on the base seat, and has liquid tanks for containing liquids, each having an entrance and an exit that is used for liquids to flow out. The pressure supply module includes a connection unit having a connection member and first flow valves, and an actuation unit. The connection member has an air intake opening and air outlet openings connected to the air intake opening. The air outlet openings respectively connect the entrances of the liquid tanks. The first flow valves are respectively disposed on the air outlet openings. The actuation unit is disposed on the base seat and connects the air intake opening. The actuation unit is for providing air at constant pressure to the air intake opening.
