Abstract: A dispenser for scented material for use during hunting includes a container body defining a cavity therein with the cavity being divided into a first compartment and a second compartment by a wall member. A reel is rotatably mounted in the first compartment and a line is trained around the reel to extend from the first compartment through the second compartment and outwardly into the atmosphere for selected payout of the line from the container body. An absorbent member is disposed within the second compartment for impregnation with animal scent material and includes an opening formed therein for passage there through of the line with the line being in contact with the absorbent material for deposit of a portion of the animal scent material on the line as it is paid out from the reel with a line retaining a portion of the animal scent material thereon after the line has entered the atmosphere from the cavity.

Abstract: A dual mode fire suppression system includes first and second, different, fire suppression nozzles. Each nozzle is coupled to a fire suppressing medium. A fire detector is coupled to at least one of the nozzles. The detector monitors an adjacent region, and, is insensitive to the medium associate with the coupled nozzle. In the presence of a detected first fire condition, the detector activates the coupled nozzle which releases the respective medium. The detector continues to monitor the adjacent region and in the absence of the first fire condition, the first nozzle is deactivated. In the presence of a detected second fire condition, different from the first condition, the second nozzle is activated.

Abstract: A fuel injector includes a center tube, a first valve separate from the center tube and surrounding a first end of the center tube and a second valve also separate from the center tube and surrounding a second end thereof. A solenoid is actuable to independently move the first and second valves and thereby control the application of fluid pressures to first and second ends of a check assembly, in turn to control injection of fuel into an associated engine cylinder.

Abstract: Devices for constraining wildfires are disclosed. The first device is a free-standing hollow structure which contains at least one lower intake duct, a vertical duct, and an upper outlet duct. This device contains curved chambers which may have baffles. This device also provides an open container for the delivery of water to the fire in the form of steam. A second device is a free-standing structure which is anchored to the ground by lines attached to spikes and supporting legs. The upper portion of the device is curved toward the fire so as to direct the fire back upon itself. There is an arcuate baffle at approximately the midpoint of the device which serves to break up the heat wave. A third device is similar to the second device in design, but is made of folding sections for ease of storage and transportation. A fourth device comprises a fire-resistant sheet which may be draped over trees or structures or may be put on the ground to form a barrier to the fire.

Abstract: A method and apparatus for flowing liquid metal through a casting nozzle includes an elongated bore having an entry port and at least two exit ports. A first baffle is positioned proximate to one exit port and a second baffle is positioned proximate to the other exit port. The baffles divide the flow of liquid metal into two outer streams and a central stream, and deflect the two outer streams in substantially opposite directions. A flow divider positioned downstream of the baffles divides the central stream into two inner streams, and cooperates with the baffles to deflect the two inner streams in the same or different direction in which the two outer streams are deflected.

Abstract: The fuel injector nozzle for a gasifier includes a protective refractory sheath that is flush mounted at a downstream end proximate the nozzle outlet portion. The refractory insert is of annular form to surround the nozzle outlet. The annular refractory member can be a one-piece structure or a multi-segment structure of preferably not more than four pieces. Whether the annular refractory member is a one-piece structure or a multi-segment structure, it is recessed in a downstream end surface of the fuel injector nozzle and retained in the recess by locking pins or by thread-like engagement between a projection and a groove that are provided on complementary inter-engaging surfaces of the recess and the refractory member. The retaining structure provided on the annular refractory member and at the recess in which the refractory member is disposed securely maintain the annular refractory protective member in position.

Abstract: A pump sprayer is disclosed for dispensing fluids such as insecticides and herbicides. The sprayer comprises a supply container which holds the fluid to be dispensed, a manually-operated piston pump, a pressure vessel or accumulator, and a manual control valve for controlling fluid dispensed through a spray wand. The accumulator includes an elastomeric bladder which is adapted to accumulate fluid from the pump and to deliver the fluid to the spray wand at a desired pressure. In order to provide a pump sprayer which can deliver fluid at a substantially constant pressure from a fluid supply contained in conventional containers, the pump and elastomeric bladder are configured to pass through the fill openings of the containers and to be secured therein during operation of the sprayer.

Abstract: A nozzle for dispensing a liquid jet, in particular for washing vehicle wscreens or headlight fronts. The nozzle includes a feed duct and at least two outlets each communicating with the feed duct via a respective communication hole. At least one of the outlet ducts is inclined relative to the feed duct, and each of the feed duct and the outlet ducts is substantially rectilinear. The nozzle further comprises a partition occupying at least a portion of the feed duct adjacent to the outlet ducts so as to subdivide the feed duct into compartments each of which communicates with a respective communication hole. The partition has the function of preventing non-uniform transit of the liquid into the outlet ducts.

Abstract: An air assisted fuel injector for an internal combustion engine includes a fuel nozzle having a fuel orifice and a targeting section cooperating with the fuel nozzle for targeting atomized fuel within the engine. A throttling section in disposed upstream of the targeting section and cooperates with the fuel nozzle. The throttling section throttles assist air prior to the air atomizing the fuel emerging from the fuel orifice. Thus, any adverse effects on fuel flow from the fuel injector due to back pressure variability downstream of the fuel nozzle are reduced. In a preferred embodiment, an air shroud is fitted on the nozzle of the fuel injector and includes both the throttling section and the targeting section.

Abstract: A decorative fountain includes a body, a motor pump housed in a water box, a water deflector and an IC battery chamber housed at the bottom of the body. The body includes a base which has a lower water trough which holds the water box and a top cover including an upper trough which attaches the water deflector at an opening thereof. The water box has a water inlet fluidly communicates with the lower water trough. The motor pump has a water outlet leading to the upper trough. Activating the motor pump, water will be pumped from the lower water trough to the upper trough and then drops to the lower water trough for continuous circulation. The IC battery chamber is located below the water troughs and thus is free from water moisture erosion. The base and the top cover may be integrally formed. The body therefore may be made water tight without additional painting work. It is simple to produce and assemble, and also more reliable and trouble free.
