A fin cover release and deployment system designed for high G forces of gun-launched missiles. In one embodiment, a pyrotechnic actuator drives actuator arms to first release and eject the fin slot covers, followed by deployment of the fins radially outward to the steering position. Following complete ejection of the covers, the fins are driven outwardly by cam surfaces along the latch arms, followed by a spring and wedge mechanism installed interiorly of the fin steering shaft to lock the fins in the fully deployed state. In another embodiment, a motor and rotating threaded shaft replace the pyrotechnic actuator.

A process and apparatus (invention) permitting the distribution of micro or submicro liter or gram (exceptionally small) quantities of liquids and powders, (hereafter materials) in patterns and quantities that are especially well-suited for ophthalmologic patient self-application of drugs to his own eye(s) with substantially no overdose. The invention is thus also highly beneficial in those many topical drug applications where overdoses should be avoided. This is particularly applicable for the eye, where overdoses can have many deleterious medical consequences. Use of the invention permits exceptionally small doses of ophthalmologic drugs. Moreover, it also permits the repeatability of the quantity size of the materials chosen for delivery. In the case of drugs, particularly opthomologic drugs, this means that the invention permits the repeated multiple distribution of the same chosen drug / carrier quantity resulting in a uniform repeatable dosage. Variation of dose from one application to another is very unacceptable. The preferred apparatus of the invention employs a venturi configuration inventively modified which uses gas under pressure to pump exceptionally small quantities of material from a reservoir for delivery. In especially preferred embodiments of the invention, said reservoir is pressurized by at least a quantity of gas at somewhat above atmospheric. prior to the removal of any material by pumping.

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.

A method of spraying an aerosol spray, comprising providing a grounded nozzle and an electrode separated by a predetermined distance; placing the electrode at a high electrical potential relative to the nozzle, thereby creating an electric field between the nozzle and the electrode; ejecting a liquid from the nozzle towards the electrode to atomize the ejected liquid into aerosol droplets or particles, so that in the applied electric field between the nozzle and the electrode the aerosol droplets or particles obtain an induced electric charge; and forming a directed spray of aerosol droplets or particles having a desired shape and with sufficient momentum and electric charge so that the directed spray of aerosol droplets or particles is deposited on a target.

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 contacting an inner surface of the face, to provide locally increased stiffness to particular areas of the face. The stiffening element includes a chamber adapted to contain a viscous substance. The viscous substance can be selected and inserted into the chamber 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.

The present disclosure presents systems, devices and methods for injection of drugs, substances and / or chemicals to a patient and for improving their effectiveness once they are injected are disclosed. Additional treatment can be applied to a tissue region on the patient into which a drug (e.g., insulin) is injected, to expose the tissue region to various forms of energy or a substance to improve the drug's pharmacokinetic and / or pharmacodynamic profile.

A ball striking device, such as a golf club, includes a head with a face having a ball-striking surface configured for striking a ball, a body connected to the face, and at least one channel in the ball-striking surface of the face. The region of highest COR response of the face is directionally enlarged toward the channel. Depending on the size, shape, and location of the channel, the face can be altered to provide greater COR response and increased energy transfer for impacts at specific locations on the face.

Separations processes and apparati capable of purifying thermally sensitive materials at high capacity. An apparatus having a rectification section and a stripping section with the stripping section having a stripping tray with 5 to 50% open area, a pressure drop from 0.02 psi to 0.2 psi and a tray efficiency during operation of the column which is equal to or greater than 20%.

An electromagnetic missile launcher is disclosed that provides greater flexibility for use with a variety of missile types and also provides potentially higher performance and efficiency as compared to prior-art electromagnetic missile launchers.

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 chainsaw is provided having a brake band disposed about a drum that rotates during advancement of the saw chain about the saw bar. An end of the brake band is biased to a position that draws the brake band tight about the drum to prevent advancement of the saw chain, and the throttle trigger of the chainsaw is associated with this biased end to push the band against the bias and release the drum when the throttle trigger is squeezed to drive the elements of the chainsaw that serve to advance the saw chain. Also provided are new concepts for associating throttling and braking elements with the throttle trigger.

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.

High molecular weight (HMW) gases are separated from an exhaust gas of a combustion source using a blower and an interior vent within the exhaust stack. The interior vent includes a vent wall having a top portion attached to the interior surface of the exhaust stack along the entire inner perimeter of the exhaust stack and a lower portion that extends downward into the exhaust stack to form an annular space or gap between the vent wall and the interior surface of the exhaust stack, and at least one opening in the interior surface of the exhaust stack between the top and bottom portions of the vent wall. The blower creates a tangential flow of the exhaust gas with sufficient centrifugal force to concentrate substantially all of the HMW gases along the inner surface of the exhaust stack. A transfer pipe removes the HMW gases from the interior vent.
