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. An angled 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 and forms a vortex at the injector exit. 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.

The airlock, conveyor and floor chain are driven by hydraulic motors and are either controlled manually or alternatively by an automatic controller.

Abstract: In a method for manufacturing a nozzle hole plate suitable for use in a fuel injection valve, a nozzle hole is formed at a predetermined angle of inclination by press-working with a punch in a thin-plate base material of a nozzle hole plate. When the nozzle hole is formed by press-working, a bluntness (shear drop) and a break face are formed at the corners of the base material at the fluid entrance and the fluid exit of the nozzle hole respectively, and as a result of the formation of this shear drop and break face the flow changes and the injection quantity increases. The injection quantity of the nozzle hole is measured for each nozzle hole plate, and its deviation from a target value is detected. Then, on the basis of the measured injection quantity value, the base material around the fluid entrance of the nozzle hole is notched by press-working using a punch. The material of the base material dimpled by the notching is pushed toward the fluid entrance of the nozzle hole and the shear drop diminishes.

Abstract: An antiseptic soap dispenser (A) is mounted to a wall by a secure mounting system (E). A latching and locking mechanism (D) inhibits tampering with the dispenser or theft of a replaceable soap reservoir (B), received within a dispenser housing (C). The housing includes a front cover (18) pivotally connected to a back plate (20). The mounting mechanism (E) removably mounts the back plate of the housing to a wall mounting plate (24), which is attached by screws or other fixing means to a wall or other suitable mounting surface. The back plate includes mounting tabs (172) which engage a corresponding releasable engagement portion (170) on the mounting plate to secure the housing to the mounting plate. A latch plate (60), is movably carried by the back plate. The latch plate provides the latching and locking mechanism (D) which releasably locks the housing in a manner which is not readily obvious to a casual observer, yet which avoids the need for a key.

Abstract: A snowmaker is comprised of a head which has an outer ring of nozzles which form a flow of primary water into droplets which move downstream preferably along paths running at a slight radially outward angle, together with a central nucleator which discharges frozen nuclei particles outwardly from a plurality of atomizers at the downstream end cap end of the nucleator. The nucleator is readily disconnectable from the ring. Secondary water flow is fed to the nucleator so it swirls at high velocity within, to greatly enhance the warming effect of the water on the nucleator parts, and to thereby inhibit accumulation of exterior ice. The secondary water is mixed with compressed air as they both enter the atomizers of the end cap. A resultant flow of nuclei from the atomizers is discharged so the flow merges with the plume of primary water droplets from the nozzle. Preferably, flat spray nozzles are used.

In a second embodiment, a plastic member is molded or formed in the shape of a water fountain splash guard/basin and the plastic member replaces the original stainless steel splash guard/basin of the water fountain.

Abstract: A water spraying control unit includes a fire extinguishing sprinkler head. The sprinkler head receives a branch pipe from a pipe line arranged in the ceiling of a building and the sprinkler head suppresses fire by discharging pressured water due to separation of a heat sensing plate and a nut supporting plate from the sprinkler head during a fire. A water spraying plate is joined with a water spraying plate bolt. The water spraying plate bolt is able to move through a through hole of a protruding portion in the outside of the sprinkler head. During a fire, the heat sensing plate and the nut supporting plate melt, enabling the water spraying plate to move downwardly thus opening a path for the pressurized water, the water spraying plate spraying the water over a wide area. Thus, a sprinkler head stored in the ceiling of a building is able to lower itself when actuated and spray water over a large area.

Abstract: A fire fighting system uses a bucket suspended from a helicopter to deposit fire retardant onto a fire from an opening in the bottom of the bucket. The bucket has a predetermined configuration and a valve for controlling the area of an opening through which the retardant is deposited when the bucket is suspended from the helicopter. A suitable mechanism, such as an electrically driven valve actuator, varies the area of the opening to deposit the retardant at a volume flow rate as a desired function of time while the helicopter flies along a drop line. The mechanism varies the area of the opening in accordance with a schedule determined before discharge is begun according to the configuration of the bucket, the flow characteristics of the opening as the valve changes the area thereof, and the initial amount of the retardant material in the bucket.

Abstract: A method serving the purpose of spraying a crop with a plant protective liquid. The liquid is sent out in the shape of a number of clouds (10) of atomized liquid in the direction of the crop (11) via a number of liquid nozzles (9) placed on a sprayer boom (8) which, at the same time, is driven across the crop (11).
