Abstract: A volume expansion feature for a fluid reservoir is provided, the volume expansion feature comprising a central recess, a plurality of channels extending from the central recess, where the central recess and the channels are positioned at least in part in a recessed surface profile. The recessed surface profile is reversibly moveable from a first inwardly directed configuration, to a second outwardly directed configuration. The central recess and the channels are configured to impart an inward bias to maintain the recessed surface profile in the first inwardly directed configuration under standard loading of the fluid reservoir. Upon increased pressure within the fluid reservoir, the recessed surface profile extends to the second outwardly directed configuration, thereby increasing the volume of the fluid reservoir.

Abstract: A coupling for joining fluid conduits includes a nut having a circumferential groove that extends at least partially along an interior surface of the nut. The nut further includes a tab opening extending through a surface of the nut for receiving the tab of a retaining clip. A cylindrical shaft extends from the nut. The retaining clip is disposed within the circumferential groove and includes a tab disposed within the tab opening of the nut. A first arc of the retaining clip extends from the tab in a first circumferential direction, and a second arc of the retaining clip extends from the tab in a second, opposing circumferential direction. The first arc includes a first knob and terminates in a second knob, and the second arc includes a third knob and terminates in a fourth knob. The second and fourth knobs are larger than the first and third knobs, respectively.

Abstract: The fluid coupling assembly for retaining a sealed joint includes the first member adapted to be connected to a first fluid conduit with a per sealing surface and a series of axially aligned serrations along with helical threads. A second member of a complementary configuration is adapted to be connected to a second fluid conduit with complementary threads and an axially extending cylindrical collar with spaced axial notches forming cantilevered beams. Each of the cantilevered beams can have teeth capable of engaging a series of serrations to provide an appropriate resistant force for both sealing engagement and disengagement. The teeth and serrations can remain in contact to provide a visual determination of a pretorqued force between the first member and the second member.

Abstract: A vena cava blood clot filter is described that is attached to the walls of the vena cava by barbed anchors. In its filtering state, the filter is cone shaped which causes the blood to be filtered. The cone shape is formed by an appropriate restraining mechanism. When it is desired to stop filtering, the restraining mechanism is released and the filter takes a cylindrical shape. The cylindrical shaped filter will then line the vena cava wall and cease filtration of the blood.

Abstract: A self-locking fluid coupling, utilized to connect two fluid conduits together, does not require the lockwiring of the coupling nut to prevent the rotation of the coupling nut. The locking mechanism comprises a rotational locking means on a ferrule member. The rotational locking means engage one or more inwardly protruding engagement members of the B-nut. The engagement of the rotational locking means of the ferrule with the engagement members of the B-nut creates resistance to circular motion, thereby resisting rotation of the B-nut and eliminating the requirement for lockwire to resist rotation of the B-nut.

Abstract: A filter system especially useful in the treatment of waste material, in particular liquid waste material which may include particulate matter therein. The filter system includes a series of filters of progressively finer porosity in order to selectively eliminate particulate (or semi-particulate) matters from a carrier material, typically but not exclusively, of a fluid or liquid nature. The filters are mounted within a housing which includes an outlet port and a plurality of inlet ports, wherein each inlet port includes a check valve.

Abstract: A nozzle assembly for a kinetic spray system includes a convergent portion, a throat portion, and a divergent portion, each cooperating together to define a passage therethrough for passing a mixture of powder particles suspended in a flow of a high pressure heated gas. The nozzle assembly further includes an extension portion attached to the divergent portion and extending to a distal end a pre-determined length from the divergent portion of the nozzle assembly. The extension portion permits a dragging force exerted on the powder particles by the flow of high pressure heated gas to act upon the powder particles for a longer duration of time, thereby permitting the powder particles to accelerate to a greater velocity than has been previously achievable.
