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 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.

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.

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.

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.
