Abstract:
A container assembly for use with a high-pressure liquid chromatography (HPLC) instrument is disclosed, in which the container assembly, when coupled to a source of pressurized gas, provides fluid medium to the HPLC instrument at positive pressure. The container assembly has an external exterior container shell, an internal fluid container for holding fluid medium, an interstitial volume between the external exterior container shell and the internal fluid container, a port for fluidly connecting the volume to a pressurized gas source, and a port for fluidly connecting the internal fluid container to the HPLC instrument. As a pressurized gas in the interstitial volume increases, fluid medium flows out of the port connected to the internal fluid bag and container assembly at a positive pressure. A system incorporating the container assembly, and method of use of the same, are also disclosed.
Abstract:
Provided is a connector including a plug to be fixed to an inner peripheral surface of an opening of a liquid storing container, and a socket to be detachably attached to the plug. The plug includes a plug body in which a first liquid outflow passage, a first liquid inflow passage, and a first gas passage are formed. The socket includes a socket body including, formed therein, a second liquid outflow passage, a second liquid inflow passage), and a second gas passage; a rotary valve having an outflow through-hole and an inflow through-hole; and a switching mechanism for switching between an open state and a closed state when the rotary valve is rotated.

Abstract:
An adhesive container. The adhesive container includes a relatively rigid canister, a collapsible bag within the relatively rigid canister, the collapsible bag containing an adhesive, a propellant in a space between the outside of the collapsible bag and the inside of the relatively rigid canister, and a valve connected to the relatively rigid canister, the valve comprising an adhesive port in selective communication with the collapsible bag and a propellant port in selective communication space between the outside of the collapsible bag and the inside of the relatively rigid canister. The invention also involves a method of filling a bag-in-can container of adhesive.
Abstract:
A flow control for use with flexible bags to push fluent material from the bags by deformation of the bags comprises first, second, and third platens mounted on a frame for movement relative to each other. The first and second platens are adapted to receive portions a flexible bag therebetween, and the first and third platens are adapted to receive portions of a flexible bag therebetween. The first platen is movable between a first position in which the first and second platens and the first and third platens each define a first space for containing the bag portions and a second position in which the first and second platens and the first and third platens each define a second smaller space for containing the bag portions.
Abstract:
A fluid-dispensing device and method of dispensing fluid comprising a container for holding the fluid, a housing having an interior in which a portion of the container is located, and a source for compressing a portion of the container disposed within the interior of the housing. When the container is compressed, the fluid exits the container to flow to a desired location. The methods of compressing the container to force the fluid out of its interior include, for example, a housing holding the container that is pressurized above atmospheric pressure; an expandable balloon positioned adjacent the container and inflated; and a plate driven by a cylinder to compress the container. It is noted that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to ascertain quickly the subject matter of the technical disclosure. The abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims pursuant to 37 C.F.R. null1.72(b).
Abstract:
A fluid delivery apparatus is provided that includes a pressure tube and a first cap assembly having a control system, with the first cap assembly coupled to a first end of the pressure tube for forming a gas-tight seal thereat. The apparatus also includes a second cap assembly coupled to a second end of the pressure tube for forming a gas-tight seal thereat, with the second cap assembly supporting a fluid container that is housed in the interior space of the pressure tube.
Abstract:
The bifunctional generator comprises a closed or self-feeding bag (1) containing the reserve of liquid (2) to be used, the bag being pressure-constrained in a chamber (3) and hydraulically coupled with the supply link (13) of a hand piece (5, 6) by a connecting hydraulic section (9). The pressure generator or delivery generator functioning mode is determined each time by the presence in the connecting section of at least one hydraulic component (19, 21) and/or a hydraulic conformation (20, 22) associated with the particular feature of the hand piece used. This invention is of interest for the manufacturers of medical appliances: aquadissection, resectoscopy, lavage, disinfecting or the like and it as useful applications for various foodstuffs.
Abstract:
A disposable fluid transport system is provided for dispensing sterile fluids from a pressure vessel. The pressure vessel has an internal chamber with an outlet opening extending therethrough. The fluid transport system includes a collapsible media bag having an internal compartment defining a sterile environment. A first end of a delivery tube is attached in fluid communication to the compartment of the media bag. Disposed at a point along the length of a delivery tube is an interface adapter. The interface adapter includes an annular flange which encircles and radially projects out from the exterior surface of the delivery tube. The gasket is formed of a resiliently flexible material and has an outside diameter that is larger than the inside diameter of the outlet opening on the pressure vessel. Once the media bag and delivery tube are positioned within the chamber of the pressure vessel, the second end of the delivery tube can be fed out the outlet opening. As a result of the flexible nature of the gasket, the gasket can also be constricted to pass through the outlet opening and then radially expanded. A clamp can then be used to seal the gasket on the outlet opening so as to seal the outlet opening closed.
Abstract:
A process is provided for ultrasonically welding a rigid thermoplastic, such as acrylic, and a flexible thermoplastic, such a polyvinyl chloride (PVC) doped with plasticizers. The rigid piece includes an energy director where the joint is to be located. The energy director includes first and second ridges running the length of the joint and a groove running between the first and second ridges. The energy director is placed against one side of the flexible piece, and an ultrasonic horn against the other side opposite the energy director. The two pieces are then welded together using standard ultrasonic technology. The shape of the energy director promotes the melting and flow of both pieces as they are being welded together.
