A valve in the flow aperture of a removable coolant reservoir enables coolant to flow between the reservoir and a coolant system while preventing the coolant in the reservoir from spilling when the reservoir is disconnected from the coolant system. A filling tube with a lower end and an air escape passage discourage users from overfilling the reservoir. Once the coolant level reaches the lower end, fluid accumulates in the filling tube, thereby indicating to the user that the reservoir is full. ...

A cardiotomy reservoir which employs an inner wall structure which defines a central receiving chamber. The receiving chamber wall is tapered inwardly to provide a smooth blood flow along an arcuate imperforate portion which extends from the top to the bottom thereof into the blood receiving chamber. Apertures in another arcuate portion of the wall member allow fluid communication between the receiving chamber and the blood treatment element. Blood flow directing means direct blood entering the ...

A method for monitoring hydrocarbon and water production from different production zones/sections in a hydrocarbon reservoir and/or injection wells and detection of different phenomena such as e.g. local variations in pH, salinity, hydrocarbon composition, temperature, pressure, microorganisms, and the difference between production of formation and/or injection water from various zones/sections. The method includes dividing regions around wells in the reservoir into a number of zones/sections, a...

A reservoir for aircraft, such as a helicopter, containing a fluid and having at least orifices in its side wall close to its bottom and to which a fluid feed and return ducts can be connected. The reservoir has to allow the aircraft to effect temporary flight phases under negative load factor, a plate having a passage, for retarding the movement of the fluid contained in the reservoir, so that the fluid, moving from the bottom to the top of the reservoir during the temporary flight phases and p...

A blood reservoir serves to suppress generation of air bubbles in blood in an extracorporeal blood circulation circuit. The blood reservoir includes a blood storage chamber for temporarily storing the blood, the blood storage chamber having blood inlet and outlet ports, and a fluid-permeable blood spouting inhibitor disposed over the blood inlet port. Since the blood flows into the blood storage chamber through the blood spouting inhibitor, the blood is prevented from being spouted into the bloo...

A venous reservoir for use in cardiotomy bypasses comprising a flexible, variable capacity bag having a vertical seal positioned between the outlets and inlets along the lower seal line. The vertical seal line is positioned off-center such that the velocity of blood decreases as it passes the top of said seal line and towards the lower outlet to increase the removal of bubbles from the blood. All ports serving the reservoir are constructed without internal projections into the reservoir to decre...

This invention pertains to improvements in the design of reservoirs for hydraulic systems, by providing self regulated temperature control for hydraulic fluids. The unique features of the reservoir of my invention include; an interconnected multi-chamber design with integrated vertical heat transfer tubes, for conductive and convective heat transfer from the hydraulic fluid to the surrounding atmosphere.

A developer reservoir in which a flexible seal member is separably bonded to the circumferential surface of an opening in a bottom portion of a reservoir body containing a developer for sealing the same opening. A portion extended from the bonded flexible seal member is spot-bonded on a plurality of portions of the bottom portion of the reservoir body so that when a considerably large pulling out force is applied to the seal member the seal member is separated first from the spot-bonded portions...

A detachable suction reservoir provides suction to a drainage and autotransfusion system coupled with a closed wound drain to facilitate drainage of blood from the wound into a substantially rigid collection container. This blood is adapted to be transferred into a blood bag which in turn may be coupled with an administration set for reinfusion. While blood is reinfusing, blood collection into the container continues. Following autotransfusion, the suction reservoir can be converted to a suction...

A plastic reservoir adapted for use with a hydraulic power pack. The reservoir includes a plastic body and a substantially plastic mounting ring which is joined to the plastic body of the reservoir. The mounting ring includes a metal reinforcing ring which is encapsulated in the plastic portion of the mounting ring.
