A reservoir tank has filling and outlet ports which are provided in a common aperture formed through the tank top.

The invention relates to a fluid reservoir with two compartments, more particularly for supplying hydraulic fluid to tandem master cylinders, this reservoir more specifically comprising two complementary, superjacent parts connected with adhesive, by thermowelding or by any other equivalent method, a central partition attached to the said parts and running across the longitudinal axis of the reservoir to divide the reservoir interior into two compartments having respective outlet orifices, at le...

An underwater gas/liquid reservoir 1, particularly designed to be used as a ballast/buoyancy tank in an offshore drilling platform, has a pressurized supply duct 2 for introducing gas into the reservoir to control the liquid level therein. The gas supply duct has two openings 8, 11, one near the bottom of the reservoir and the other near the top. A movable straddle packer 14 is disposed in the gas supply duct for selectively closing the bottom opening 8 so that gas is allowed to flow only throug...

A water collection device is disclosed which provides a source of usable water from collected surface and waste water, and comprises three concentrically arranged compartments which function as a septic tank. The innermost compartment performs a settling function and delivers clarified water through a liquid seal to the intermediate compartment, from which it is drawn for use. Excess water in the intermediate compartment overflows into the outermost compartment, from which it is discharged as wa...

A sensor for determining the presence of a particular volume of fluid within a plurality of reservoirs maintained as a portion of an automatic mixed drink dispenser. Fundamentally, the invention includes electrical contacts maintained within each of the various reservoirs, the reservoirs being aligned into rows and columns to form a matrix. A multiplexing circuit is interconnected to the rows of such reservoirs while a sensing circuit is interconnected to the columns thereof. The addressing of t...

A reservoir for the collection, purification, and storage of blood during surgical procedures which comprises a hollow blood storage casing having a hollow, perforated member within said casing extending from end-to-end thereof. Blood defoaming means and a filter are carried by the hollow member, so that the blood defoamer and filter are noncollapsible, and extend the entire length of the chamber within the casing, with one of the ports communicating with the interior of the hollow member, so th...

A closed-loop hydrostatic drive unit having a variable displacement fluid pump driven by an electric motor for generating high-pressure fluid adapted to be communicated to a fluid motor and returned to the fluid pump via a high-pressure filter. The closed-loop hydrostatic drive unit is mounted to a rectangularly-shaped reservoir housing having upper and bottom surfaces connected by side walls and end walls to define therein a chamber for the storage of fluid at a low pressure which is communicat...

A measuring reservoir for measuring the volume of the second component of a two-component mixture by the given volume of the first component and the given ratio of the mixture components is described. The reservoir has a housing of transparent material with measuring scales marked on the outside. The first scale is for the measurement of the volume of the first component, the second scale is a ratio scale on which there are marks corresponding to the ratio of the volumes of the components. One o...

A portable cartridge reservoir that includes first and second rectangular cups having handles projecting from first ends thereof, with the cups being pivotally connected on their second ends, and when in a first position, the cups having the free rectangular edges thereof in abutting contact. A tray is provided that is removably supported in the first cup. The tray supports a number of cartridges in spaced groups, with the spacing of the cartridges in each group being such that they may be slida...

Venous reservoirs are interposed between the patient and the arterial pump and serve to remove air bubbles and provide compliance that accommodates variations in the volume of blood circulating in the extracorporeal circuit during cardiopulmonary bypass (CPB). The invention is a reservoir that incorporates automated means to remove air bubbles from the venous line prior to the blood entering the arterial blood pump. In another form, the reservoir includes means that handles foam prior to the blo...
