F16K 4300

US Classification:

12820021

Abstract:

A method of installing an anti-siphon flow restricter into a gas flow lumen of a nebulizer includes providing an anti-siphon flow restricter having a side wall conforming to a cross section of the gas flow lumen, first and second ends at opposite ends of the side wall and an elastomeric diaphragm closing the first end of the side wall. The anti-siphon flow restricter is axially inserted into the gas flow lumen with the diaphragm leading. The diaphragm is slit and allowed to self-bias closed.

US Classification:

12820018

Abstract:

A nebulizer (10) has a nebulizer top (12) defining an aerosol outlet (66) and a reservoir bottom (14) defining a liquid reservoir (21) and a threaded connection (38,68) between the reservoir bottom (14) and the nebulizer top (12). A nebulizing structure (24,46) within the nebulizer provides an aerosol to the aerosol outlet (66). A continuous flow adaptor (16) for the nebulizer has a side wall (90) with first and second open ends (94,100) defining a spacer interior. An orifice (116) in the side wall (90) of the adaptor (16) allows for fluid communication with the adaptor (16) interior from outside of the adaptor (16). A luer connector (118) is provided on the side wall (90) of the adaptor (16) for connecting the orifice (116) in fluid tight communication with a fluid supply. The adaptor (16) includes threads (92,98) proximate the first and second open ends (24,100) for cooperatively engaging the threaded portions (38,68) of the reservoir top (12) and reservoir bottom (14).

International Classification:

A63H 2700
B65D 2308

US Classification:

446 71

Abstract:

An insulating device for keeping a container of liquid from losing its thermal content to its environment that can double as a recreational throwing toy. The device is constructed of two open-ended cylinder bodies, one inside the other. The inner cylinder 8 of an insulating material for the purpose of keeping a container of liquid cold (or warm) is adhered to the inner side of the outer cylinder 10 of a stiff, yet flexible plastic composite that provides aerodynamic stability and durability. A uniformly weighted ring 2 encircles the forward end of the device sandwiched between the two cylinders, thus providing a forward center of gravity that produces stability in flight. The forward edge 6 of the device is rounded for durability and aerodynamics, while the rear edge 4 is rounded and slightly tapered to reduce drag while in flight. The device, when propelled through the air and provided with a rotation about its horizontal axis will fly in a smooth and calculatable manner. The device, when slipped over a cylindrical beverage container will provide an insulating property for keeping the liquid within at a desirable temperature.

Abstract:

A nebulizer (10) has a housing (12,14) including an aerosol outlet (22) and a bottom wall (52) with a side wall (50) connected thereto defining a reservoir (54) for a liquid (106). A gas jet (58) extends along a longitudinal axis (60) of the housing (12,14) and through the bottom wall (52) of the housing (12,14), the gas jet (58) defining a gas flow lumen (66) having a gas orifice (64) at its distal end. A liquid nozzle (16) having a liquid orifice (102) at a distal end corresponding to the distal end of the gas jet (58) surrounds the gas jet (58). The liquid orifice (102) is spaced from the gas orifice (64) for nebulization of liquid (106) fed to the liquid orifice (102). A diaphragm (126) made of an elastomer has a slit (130) which is biased closed. Cooperating shoulders between the diaphragm (126) and the gas flow lumen (66) maintain the diaphragm (126) in the gas flow lumen (66) with the slit (130) transverse the length of the lumen.

Abstract:

In accordance with an embodiment, described herein is a system and method for connection concentration in a database environment. A transparency engine provided between client applications and a database can include a connection pool (e.g., UCP connection pool). The transparency engine can operate as a proxy engine for the database and as a session abstraction layer for the client applications, to enable the client applications to utilize features provided by the connection pool without code changes. The transparency engine can receive application connections from the client applications, and concentrate the application connections on a smaller number of database connections maintained in the connection pool.

Abstract:

Described is a system, method, and computer program product is provided that implements high-volume data ingestion in a relational database system. A middle-tier structure is provided that sits between the IoT data producers and the back-end database system. Data records are gathered together and organized at the middle tier, and groups of those records are ingested on a group-basis into the database in a manner which bypasses standard SQL engine processing.

Abstract:

In accordance with an embodiment, described herein is a system and method for high availability and load balancing in a database environment. A transparency engine can be provided between client applications and a database, and can operate as a proxy engine for the database and as a session abstraction layer for the client applications, to enable the client applications to utilize database features provided by the connection pool without code changes to the client applications. The transparency can keep track of session states, request boundaries and cursors to efficiently reuse the database connections across the client applications. The transparency engine can use the request boundaries and indicators from the database to detect safe places to drain database connections in the event of database outages.
