A composite filtration medium web of fibers containing a controlled dispersion of a mixture of sub-micron and greater than sub-micron diameter polymeric fibers is described. The filtration medium is made by a two dimensional array of cells, each of which produces a single high velocity two-phase solids-gas jet of discontinuous fibers entrained in air. The cells are arranged so that the individual jets are induced to collide in flight with neighboring jets in their region of fiber formation, to cause the individual nascent fibers of adjacent jets to deform and become entangled with and partially wrap around each other at high velocity and in a localized fine scale manner before they have had an opportunity to cool to a relatively rigid state. The cells are individually adjusted to control the mean diameters, lengths and trajectories of the fibers they produce. Certain cells are adjusted to generate a significant percentage of fibers having diameters less than one micron diameter, and which are relatively shorter in length and certain other cells are adjusted to generate a significant percentage of structure-forming reinforcing fibers having diameters greater than one micron diameter which are relatively longer in length. By employing appropriate close positioning and orientation of the cells in the array, the sub-micron fibers are caused to promptly entangle with and partially wrap around the larger reinforcing fibers. The larger fibers thereby trap and immobilize the sub-micron diameter fibers in the region of formation, to minimize the tendency of sub-micron diameter fibers to clump, agglomerate, or rope together in flight. Also, the larger fibers in flight are made to form a protective curtain to prevent the sub-micron fibers from being carried off by stray air currents.

The COIL gain generator system includes a reactor for producing singlet delta oxygen and a mechanism for mixing high momentum diluent with the singlet delta oxygen and with iodine for producing a high momentum, low static temperature mixture of the singlet delta oxygen, diluent and iodine. The singlet delta oxygen and the iodine react to produce excited iodine atoms which can lase efficiently due to the low static temperature and can, after lasing, recover to high pressure in a diffuser due to the high momentum of the mixture. This provides the capability of using a chemical pump which allows a completely sealed system with no outside exhaust.

A personal flight vehicle including a platform base assembly that provides a surface upon which the feet of an otherwise free-standing person are positionable, and including a plurality of axial flow propulsion systems positioned about a periphery of the platform base assembly. The propulsion systems generate a thrust flow in a direction substantially perpendicular to the surface of the platform base assembly, where the thrust flow is unobstructed by the platform base assembly. The thrust flow has a sufficient intensity to provide vertical takeoff and landing, flight, hovering and locomotion maneuvers. The vehicle allows the pilot to control the spatial orientation of the platform base assembly by the movement, preferably direct, of at least part of his or her body, and the spatial movement of the vehicle is thus controlled.

An airbag module is disclosed which, in one configuration, inflates from a vehicle seat to protect a vehicle occupant against lateral impact. The airbag module has a cushion with a pelvic chamber and a thoracic chamber. The airbag module also has an inflation assembly including an inflator within a housing inside the cushion. The housing has an aperture disposed within each of the chambers such that, when the inflator deploys, the pelvic chamber is inflated to a relatively higher pressure. The inflator may be moved axially within the housing to control the pressure ratio between the chambers. The housing is attached to the vehicle seat via attachment features that may be located at a variety of positions with respect to the remainder of the housing to facilitate adaptation of the inflation assembly to multiple cushion and vehicle configurations.

A dumpster having a moveable false floor which moves from a bottom of the dumpster toward a top opening when the dumpster is tilted to a substantially inverted orientation during collection of trash. The moveable false floor has freedom to move a predetermined length toward the top opening, where upon reaching the predetermined length a restraining means abruptly stops the floor causing the dumpster to shake dislodging adhered trash. Upon being returned to an upright orientation the moveable false floor moves back to the bottom.

An electrical device having a housing and moisture-sensitive electrical structural units situated in the housing, having a pressure compensation element situated in a housing part, which avoids, preferably prevents, the ingress of moisture, the pressure compensation element including a diaphragm which is permeable to gas, having an impact protection element situated in front of the diaphragm, which at least avoids spraying a liquid directly onto the diaphragm, wherein the impact protection element is in one piece part of the housing part.

An air duct for supplying ambient air in an aircraft includes an air inlet, a flow duct portion and a feed device that is devised to feed ambient air through the air inlet and the flow duct portion. A flow control flap closes the air inlet in a first position, releases a first flow cross-section of the air inlet in a second position and releases a larger second flow cross-section of the air inlet in a third position. The flow control flap is designed to not increase drag significantly in the second position while still enabling flow through the flow duct portion, while increasing drag to increase air fow through the flow duct portion in the third position.

The invention concerns a spray nozzle for a powder duster for dusting freshly printed products with a connection for a tube for supplying a powder-air mixture, a distribution chamber and at least two nozzle channels which branch off from the distribution chamber like a fan, wherein the opening angle of the outer nozzle channels limiting the fan subtends an angular range of 5° to 20°, in particular an angular range of 8° to 15°, and preferably 12°. The invention also concerns a spray bar with spray nozzles of this type, a powder duster comprising spray nozzles of this type, and a method for dusting freshly printed products.

Cooling systems and the methods of cooling filaments using the cooling systems are disclosed. One embodiment of the cooling system includes a layer of nozzles that spray air on the filaments above a pre-pad water spray. Alternatively, another cooling system utilizes air-atomizing nozzles to spray a mixture of air and water on the filaments. The cooling systems provide an improved distribution of cooling fluid particulars to enhance the cooling of the filaments. The sprays from the nozzles have a higher momentum and are able to penetrate deeper into a filament fan than conventional cooling systems. The results are an improved temperature uniformity among the filaments and an overall reduction in temperature of the filaments prior to the application of size material.

A thermionic flat electron emitter has an emitter arrangement with an emitter plate having slits therein that produce serpentine current paths. The emitter arrangement has a structure that, in operation, causes the electron density of the emitted electrons to be lower in the central region of the emitter plate than in a region adjoining the central region.

A doctoring system is disclosed for cleaning a moving surface in a papermaking machine, and the doctoring system includes a doctor blade and fluid assist system. The doctor blade is coupled to a doctor blade holder, and the doctor blade holder is coupled to a doctor-back. The fluid assist system is for providing a fluid under positive pressure that is higher than atmospheric pressure. The fluid is directed in a direction generally opposite a direction of movement of the moving surface such that fluid of high momentum is provided to impinge on water resident within the moving surface and adjacent a leading edge of the doctor blade during movement of the moving surface.

The invention presented in this application is a novel, highly customizable, magnetic spinning device. The main components of the invention are a magnetic hub, numerous magnets, a bearing or similar rotation point, and a finger hold. These components may or may not be permanently attached to one another and may or may not be separate bodies. The main aspect of this invention is the magnetic hub. It is titled such not because it itself is necessarily magnetic, but because it provides positioning and support for the magnetic pieces allowing for customization.
