A method of expanding tobacco involves introducing a steam flow and a tobacco material into a duct having an inlet and an outlet and defining an arcuate flow path. The tobacco is entrained in the steam flow and conveyed along the arcuate flow path and toward the outlet. The presence of the steam results in volumetric expansion of the tobacco as the steam and entrained tobacco travel along the flow path. The steam and entrained tobacco are then collected and separated. As such, an expanded tobacco is provided.

The present invention relates to circumferential seal ring segments positioned around a rotating shaft so as to prevent fluids from leaking from a lubricant sump during both low and high pressure conditions. The circumferential seal is comprised of a plurality of adjoining annular ring segments facing the rotating shaft. Each sealing ring segment includes a dead end circumferential groove on a shaft-side face of each sealing ring such that, when the segments are joined, the circumferential dead end groove of each segment extends arcuately in the direction of shaft rotation. At least one additional groove is contained on the shaft-side face of each sealing ring segment. The additional groove(s) directs and creates pressurized air within the dead end circumferential groove, either directly or indirectly maintaining a seal between the ring segments and the shaft. A bleed hole may also be provided to create a seal between each sealing segment.

An assembly and process designed to neutralize a landmine having a case loaded with an explosive charge set to detonate upon actuation. The assembly includes a housing provided with a chamber loaded with a solid propellant. One of the ends of the housing is exposed to permit the loaded propellant to communicate the chamber with the outside atmosphere. The propellant is remotely ignitable via a remotely operable igniter. The first end of said housing is constructed and arranged and the solid propellant is present in an amount and composition suitable for generating, upon ignition of the solid propellant, a plume sufficient in burn time and temperature both to penetrate through the case of the landmine positioned in spaced relation to the first end and to initiate controlled burning of the explosive charge of the landmine so that detonation of the explosive charge is either avoided or reduced due to pre-detonation partial consumption of the explosive charge by burning.

A ball striking device, such as a golf club, includes a head with a face having an outer surface configured for striking a ball, a body connected to the face, and an insert connected to the face and forming a portion of the outer surface. The density and/or friction properties of the insert may be different from those of adjacent portions of the face. Depending on the size, shape, and location of the insert, the moment of inertia of the head may change, the center of gravity of the face may shift, and/or the degree and direction of spin on the ball resulting from impacts may change.

A thin air outlet structure to a vehicle compartment exhibiting excellent directivity while ensuring sufficient volume and velocity of air conditioning air stream. In the air outlet structure 10, delivery direction of the air stream can be altered by altering the posture of a pair of fins 16 provided at a middle portion 13 in the flow direction in a case 12. Since the air outlet 20 does not require a plurality of fins for altering the delivery direction, the air outlet 20 can be made thin. Since the delivery direction of the air stream can be altered by means of the pair of fins 16 and the number of the fins 16 is small, flow of air is not impeded in the flow path within the case 12 and effective cross-sectional area of the flow path within the case 12 can be ensured. Consequently, sufficient volume and velocity of air stream can be secured. Furthermore, the size for each blade of the fins 16 can be increased by the decrease made in the number of fins 16. The air conditioning air stream excellent in directivity can be obtained.

A device combines skin tissue cooling and microdermabrasion and includes: a source of ice crystals; a mechanism for propelling the ice crystals at a plurality of velocities; a controller, the controller being programmable to increase or decrease the velocity of the propelled ice crystals; the controller controls the velocity of the ice crystals to range from low speed to impinge upon and cool the skin tissue to a higher velocity to cause microdermabrasion of the skin tissue.

A burner having a fuel tube, a heat recuperator disposed at least partially around the fuel tube, a cover disposed at least partially around the heat recuperator, and a housing coupled to the fuel tube. The housing has an air inlet, an exhaust outlet, and an eductor body. The eductor body has a first pathway for directing inlet air toward the heat recuperator and a second pathway directing inlet air into the exhaust outlet.

A ball striking device, such as a golf club head, has a head that includes a face configured for striking a ball and a body connected to the face, the body being adapted for connection of a shaft thereto. The head may include one or more stiffening elements or other structures engaging the face to provide locally increased stiffness to particular areas of the face. The stiffening element can be movable to create regions of increased stiffness in desired locations, leaving other regions of the face to have increased flexibility as compared to the stiffened regions.

An ink adapted for forming conductive elements is disclosed. The ink includes a plurality of nanoparticles and a carrier. The nanoparticles comprise copper and have a diameter of less than 20 nanometers. Each nanoparticle has at least a partial coating of a surfactant configured to separate adjacent nanoparticles. Methods of creating circuit elements from copper-containing nanoparticles by spraying, tracing, stamping, burnishing, or heating are disclosed.

The air screen flying insect repellant system includes a series of perimeter blowers designed and arranged to circulate a vertical air curtain from one blower to the next to create a physical barrier of continuous moving air around the “insect free” zone. The velocity of the moving air curtain is maintained between the blowers by the action of the tangential fans, which draw air into the blower from the adjacent blower, as well as propelling air outward toward the next adjacent blower. The blowers maintain the velocity of the air curtain at sufficient velocities (generally over 3.6 miles per hour) to prevent mosquitoes from passing between the blowers. The blowers also incorporate a mechanism for dispersing insect repellent or fragrance into the air curtain. The dispersion mechanism allows insect repellants to be actively or passively introduced into the air curtain to further deter the encroachment of mosquitoes and other flying insects. The air screen repellant system can be adapted to provide an “insect free” zone for any outdoor or “open air” application.

A pulsed gliding arc discharge (PGD) reactor includes an ignition coil driven by a pulse generator which is connected to a pair of divergent electrodes fixed by a reactor housing with a fluid inlet and outlet. Hydrogen peroxide and dye degradation can be carried out with a PGD reactor according to the invention with efficiencies that are more than two orders of magnitude greater than a conventional ACG reactor based on the calculated specific energy yield.

A heat exchanger is provided for warming fuel prior to introduction of the fuel to an engine, the heat exchanger including: a fuel inlet and a fuel outlet; a heat exchange matrix having heat transfer components past which the fuel flows between said inlet and said outlet and which are arranged to be heated; and swirl inducing means arranged between said inlet and said matrix arranged to cause fuel from said inlet to swirl prior to entering said matrix. By causing the fuel to swirl prior to entering the heat exchange matrix, entrained ice in the fuel can be caused to concentrate at an outer region of the heat exchanger thereby allowing fuel to continue to flow through the heat exchanger to the engine even when ice is present in the fuel.

An relatively small anti-personnel mine device having a housing about 2 to about 3 inches in diameter, by about 2 to about 4 inches in length, which device projects a dispersion pattern of ⅛ to ⅜ inch diameter hard fragments over at least a 3 to 4 inch radius circle to neutralize a typical, buried, anti-personnel mine. The device contains about 125 to 190 grams of plastic explosive, which when detonated impacts a gas push plate against which an array of the fragments are lodged—the gas push plate and the fragments being encased in a puck shaped matrix of plastic or resin. The effect of the device is such that in addition to neutralizing the mine, the overburden atop the buried mine is expelled exposing the mine, providing enhanced safety in removal and a warning if the mine is daisy-chained to other mines.
