Abstract: Cartridge packaging for nicotine delivery systems are provided. Various embodiments of cartridge packaging are described that include or use one or more perforations or perforating patterns separating the cartridges. In one embodiment, for example, a cartridge pack can include a plurality of cartridge pack cavities that are each configured to receive a vaporizer cartridge and separated by a vertical perforation region, and a void cavity separated from the plurality of cartridge pack cavities by a horizontal perforation region. Related systems, methods, and articles of manufacture are also described.

Abstract: A gas dispersion system may include a drive mechanism, a drive shaft having a proximal end operably coupled to the drive mechanism, extending to a distal end, and configured to transfer rotational motion and torque, a mixing element arranged at or near the distal end of the drive shaft including a hub and multiple blade pairs, each blade pair including an upper blade and a lower blade secured to the hub and cantilevering freely and generally radially away from the hub.

Abstract: An impeller, which may be a dual-direction mixing impeller, may include a hub and a blade extending from the hub, the blade having a substantially flat root portion and a twisted outer portion, the blade terminating at the twisted outer portion.

Abstract: A mixer impeller having high efficiency blades. The impeller may include a central hub and a plurality of blades attached to and extending radially outwardly from the hub such that leading edges thereof are inclined upwardly from trailing edges thereof.

Abstract: A fuel-water separator for diesel engines has a coalescing media and baffle plates through which diesel fuel and water pass upwardly, separation thereof being effected by reducing emulsification of water with fuel, and by passing of heavy particulates to the bottom of the separator.

Abstract: A static mixer element and a method for mixing first and second (or more) fluids using a static mixer element. The static mixer element includes a directional flow axis which points in an intended downstream direction opposite to an intended upstream direction. The static mixer element also includes interdigitated static mixer blades. The blades each have a concave side which faces generally in the intended upstream direction at an acute angle with respect to the intended upstream direction. The static mixer element is placed in a pipe with the directional flow axis of the static mixer element pointing downstream. The first and second fluids are introduced into the pipe upstream from the static mixer element. Optionally, other static mixer elements can be added downstream, wherein even-numbered elements are rotated ninety-degrees about the directional flow axis from odd-numbered static mixer elements.

Abstract: A disposable intake air cleaner for internal combustion engines, particularly relatively large truck engines and the like. The air cleaner accommodates engine intake air ducts of different sizes as well as installation of the cleaner on a motor vehicle without precise alignment of the air cleaner with the engine intake air duct and without the use of a hump hose or other flexible air conduit between the air cleaner and a fixed engine intake duct. The air cleaner has a flexible air duct coupling integrally formed, by a unique method, with a sealing bond between the air cleaner housing and air filter. A reusable flexible boot connects the air cleaner inlet to an engine air intake passage in the vehicle hood when the cleaner is mounted in the engine compartment and the hood is closed.
