Abstract: A device for applying free-flowing material to a movable substrate (1), especially for intermittent application of liquid adhesive. At least one supply channel (46) feeds free-flowing material and at least one nozzle unit (8) with at least one output channel is connected with the supply channel (46) and ends in an output orifice for delivering material. A valve mechanism interrupts the flow of material and includes a movable valve body (14) and a valve seat (44). The valve body (14) interacts with the valve seat (44) in such a way that the flow of material is interrupted by movement of the valve body (14) to a closed position and released by movement into an open position. The valve body (14) comes into contact with the valve seat (44) to interrupt the flow of material through a movement contrary to the direction of flow of the material.

Abstract: A drive source for feeding extinguishing medium into at least one spray head (2, 3) for extinguishing fire has a liquid source (5) and a gas source (9), apparatus for mixing the liquid and gas from their sources (5,9) and apparatus for transporting the mixed liquid and gas to the spray head (2, 3). In order for the drive source to control dosage of the gas into the liquid and, preferably, substantially even and small droplet size for a substantially long time during the extinguishing, the apparatus for mixing the liquid and gas has a piston-and-cylinder apparatus (50) including a first piston (12) in a first cylinder (10) and a second piston (13) in a second cylinder (11) for providing simultaneously at each stroke both liquid and gas to the apparatus or transporting the mixed liquid and gas.

Abstract: A device for feeding a controlled volume flow of liquid to a spray nozzle for automatic spray application. A conduit defines a flow path from a liquid source to the spray nozzle. A displacement pump type member is arranged in the conduit. A driver drives the displacement pump type member with the movable parts thereof with a speed determined by the actual volume flow through the conduit. Elements arranged in the conduit upstream of the displacement pump type member supply the flow of liquid through the conduit to the displacement pump type member and properly feed the liquid in the conduit. A valve is located in the conduit. A regulator regulates the volume flow through the conduit by regulating the throttling degree of the valve means. A first measurer measures the pressure of the flow in the conduit downstream of the displacement pump type member. A second measurer measures the pressure of the flow in the conduit upstream of the displacement pump type member.

The apparatus also includes a body removably secured to an upper portion of the container. The body has a fluid inlet, a first fluid outlet, a second fluid outlet, and a central passage defined therein. The central passage is in fluid communication with each of the fluid inlet, the first fluid outlet, and the second fluid outlet. The central passage is also in fluid communication with the mixing chamber such that each of the fluid inlet, the first fluid outlet, and the second fluid outlet is in fluid communication with the mixing chamber. Moreover, the apparatus includes a cap secured to the first fluid outlet of the body so as to prevent fluid from advancing through the first fluid outlet. Yet further, the apparatus includes a sprinkler assembly secured to the second fluid outlet of the body.

Abstract: The invention is directed to a stable capillary microjet and a monodisperse aerosol formed when the microjet dissociates. A variety of devices and methods are disclosed which allow for the formation of a stream of a first fluid (e.g. a liquid) characterized by forming a stable capillary microjet over a portion of the stream wherein the microjet portion of the stream is formed by a second fluid (e.g. a gas). The second fluid is preferably in a different state from the first fluid--liquid-gas or gas-liquid combinations. However, the first and second fluids may be two different fluids in miscible in each other. The stable capillary microjet comprises a diameter d.sub.j at a given point A in the stream characterized by the formula: ##EQU1## wherein d.sub.j is the diameter of the stable microjet, = indicates approximately equally to where an acceptable margin of error is .+-.10%, .rho..sub.1 is the density of the liquid and .DELTA.P.sub.g is change in gas pressure of gas surrounding the stream at the point A.

Abstract: An injector tip for burning aggregates for the mixing of fuel constituents, particularly fuel gases, auxiliary combustion gases and possibly liquid fuels is suggested which comprises feed ducts for the individual fuel constituents. The feed ducts of the individual fuel constituents are each preferably formed by a group of axial bores arranged on a circle, in which case the groups of axial bores assigned to the individual fuel constituents are arranged on concentric circles. According to the invention, the first feed ducts assigned to a first fuel constituent lead into first injector nozzle bores having a reduced cross section which in turn lead into a first radial injector gap. For the mixing of the first fuel constituent with at least a second fuel constituent, the second feed ducts assigned to the second fuel constituent must also lead into the first radial injector gap.

Abstract: A unit fuel injector is provided comprising an injector body containing a pumping chamber and a valve element provided for movement between (i) an advanced position wherein a supply passage communicates with the pumping chamber through a transfer passage and (ii) a retracted position wherein communication between the supply passage and the pumping chamber is blocked to allow fuel to flow from the pumping chamber through the transfer passage and out the discharge orifice. In one embodiment the valve element includes a control valve integrally formed with a tip valve, and a force balancing element for tending to balance the forces acting on the valve element by reducing the effective cross-sectional area upon which fluid pressure operates. The control valve, whether formed integral with or separate from the tip valve, extends through the solenoid to engage a valve seat formed adjacent the pumping chamber.

Abstract: An automatic washing apparatus designed to travel on a single I beam track that can be easily mounted in an existing self-service car wash bay. This apparatus is unique within itself since the trolley apparatus that supplies water and chemicals to the water boom manifold is driven entirely by a screw gear apparatus. The water boom manifold swing is also unique, being rotated by a single half spur gear that is rotated by striking a gear rack at either end of the I beam. An improved embodiment features an adjustable gear rack assembly at one end of the track which is adjusted to shorten the linear travel between end turns in response to signals from vehicle position indicating devices in order to efficiently wash smaller cars. The improved embodiment also includes a smoother vibrationless screw drive and a more rigid one-way clutch bearing support for the rotating members.

Abstract: A fuel injection valve for air-compressing internal combustion engines comprises a nozzle holder, a nozzle body and a pintle, which is operable by the application of fuel pressure against the force of a closing spring, which is accommodated in a spring chamber of the nozzle holder. The pintle cooperates with a damper, which comprises a fuel-filled damper chamber, which opens into a constricted passage. A separate damper piston is interposed between the pintle and the damper chamber and enters the damper chamber and is non-positively connected to the pintle. To provide an inexpensive and highly effective damper, either the damper chamber is formed in an adapter, which defines that end of the spring chamber of the nozzle holder which is adjacent to the pintle, the adapter contains the damper piston, which is used to transmit force between the closing spring and the pintle.
