Abstract: A fuel injector for an internal combustion engine is disclosed. In the fuel injector, an opening on the outer side of the injection hole has a width generally larger than a height thereof. The width of the injection hole is gradually narrowed inward so that the fuel is injected at a predetermined angle in the direction of width. The height of the injection hole is nearly uniform in the direction of injecting the fuel within the predetermined angle in the direction of width. A height at both ends of the opening on the outer side of the injection hole is larger than the height at the central portion thereof.

Abstract: A water geyser assembly comprises an inner pressurizable container and an outer shell both formed from a glass fibre reinforced plastics material. A polyurethane foam material fills the void defined between the inner container and the shell. A fitting mounting land formed with a number of apertures is provided at one end of the inner container for receiving fittings in the form of a pair of flanged spigot portions which are externally threaded and which are bridged at the flange. The flange locates against an inner surface of the fitting mounting land via sealing rings, and lock nuts are screwed down over each of the threaded spigot portions which project through the apertures so as to form a pressure tight fit. The fittings are thus locked mechanically to the mounting land without being laid in glass fibre during manufacture. Water inlet and outlet conduits, a heating element assembly and a pressure relief valve are in turn mounted in communication with the spigot portions.

Abstract: An ultrasonic angular measurement system is disclosed. The system is comprised of three parts, a control box used to collect and process data, an ultrasonic transducer, and a reflector block. The reflector block is configured so that it intercepts transmitted pulses received over a wide range of angles back to the transducer. All the components are self contained within a transportable housing which is attached to the aircraft deck during measurement of tip-off angle. The range of angle measurement is permitted because of the use of the unique reflector block which comprises a plurality of reflector segments for reflecting ultrasonic pulses transmitted at various ranges of angles.

Abstract: Apparatus and method for depositing salt granular materials upon a highway pavement at practical speeds. The deposition forms two narrow bands of the salt through utilization of two impeller-based mechanisms which are canted downwardly at an acute angle toward the pavement. The dump bed of trucks utilizing the apparatus is maintained in a down orientation through the utilization of a salt transport mechanism implemented as dual augers extending the length of the truck bed. Two embodiments of the apparatus are described each being self-contained and mountable upon a truck bed with relative ease. In one embodiment, a brine formation tank of generally triangular cross-sectional configuration is combined with a brine holding tank to form the sides of a V-box hopper structure. The brine formation tank is charged with salt and water to form a saturated brine which is permitted to migrate through a baffling system to the brine holding tank.

Abstract: A fluid delivery and removal mount for a stationary hydraulic roller shaft is disclosed as having a housing surrounding an annular support member which in turn supports the stationary roller shaft. The housing defines a pair of radially extending fluid conduits as does the annular support member. These fluid conduits in turn couple with a matched pair of radially oriented ports defined by the shaft. The shaft ports intersect a pair of axially extending fluid conduits formed in the shaft that serve to deliver and remove fluid from a hydraulic motor in roller. The annular support member preferably has a convex outer surface to match a concave inner surface of the housing thereby approximating the functionality of a self-aligning bearing. To facilitate off axis positions of the shaft, the fluid conduits of the housing are oversized compared to those of the annular support member. Optional circumferential seals located at the housing-support member interface limit fluid migration to the environment.

Abstract: A generator/dispenser for mono-dispersed aerosol, with droplet size precisely controlled by a stepper motor and a nozzle array having a great number of operational micro-vias, and with fluid volume dosage control. A specified dose is delivered over an accurately controlled interval of time, by decrementing the volume of a fluid reservoir upon each of a specified number of control pulses to a stepper motor, which moves a ball screw linear actuator with great precision on each control pulse. The reservoir is closed at the aerosol delivery position by a nozzle array, which is a thin sheet with myriad micro-via holes. The micro-vias are of the same dimensions and orientation, producing for a medical inhaler the desired micro-droplet volume, for example the volume of a 3-.mu.m diameter droplet from each micro-via, for each pulse.

A first of the ends of the bypass conduit is positioned adjacent the proximal end of the main conduit. A second of the ends of the bypass conduit is positioned adjacent the distal end of the main conduit. A container is fluidly connected to main conduit between the first and second ends of the bypass conduit. A rotatable dispensing ball is interposed between the container and the main conduit. A bypass valve is positioned adjacent the proximal end of the main conduit and the first end of the bypass conduit for selectively opening and closing passage of fluid through the main conduit and the bypass conduit, the bypass valve.

Abstract: In an automatic on-off sprinkler, water enters an inlet and passes through a hollow interior region to the outlet. A reciprocating member in the hollow region normally blocks the outlet when water entering a narrow passageway fills a central chamber above the reciprocating member. A large gap between the hollow region ID and the reciprocating member OD permits friction-free movement of the reciprocating member. A flexible, water-tight diaphragm seals the central region, preventing liquid entering the narrow passageway from communicating with a lower region from passing to the outlet. A sensor detects an emergency condition, unsealing a control opening larger than the narrow passageway, allowing liquid to rapidly escape through the unsealed control, dropping the pressure in the central region, whereby a pressure imbalance lifts the reciprocating member closing the outlet. When the control opening is resealed, liquid pressure in the central region sealed by the water-tight membrane increases.

Abstract: A figure eight mechanism moves a thermal spray gun over a substrate such that the deposit pattern has a figure eight configuration. The mechanism and thereby the thermal spray gun and the pattern are traversed along the substrate. The mechanism is such that, when driven by an input drive of constant speed, the deposit travels along the configuration at a non-uniform velocity. A drive system provides an input drive with varying speed so as to reduce the non-uniformity of the velocity. In one aspect a motor has varying speed, and in another aspect a linkage between a constant speed motor and the mechanism provides the varying speed.

Abstract: A tension-actuated submerged dispenser for discharging a liquid of one composition into liquid surroundings constituted by a liquid of a different constitution is useful for unattended employment to maintain a certain quality of composition in the surroundings. On the other hand, the quality of composition of liquid in the dispenser can be jeopardized if liquid from outside the container is allowed in, as has been the case with some earlier known submerged dispensers which employed a displacement liquid. In order to develop the necessary pressure to express a liquid through an orifice in a submerged container into which no such displacement liquid is allowed entry, a system of actuating a reduction of enclosed volume by means of tensing a container between opposed end-effectors has been developed. The source of pulling force can be either an externally attached weight or float, or a dispensed liquid which is differentiated as to specific gravity from that of the liquid surroundings.

Abstract: An apparatus for generating a mist for use in a centralized, pressurized gas-driven mist generating system is disclosed in which a frame member is formed with a mist generating passage, a pressurized gas inlet passage connecting with the mist generating passage, and a liquid inlet passage connecting with the mist generating passage. The mist generating passage is adapted to receive a gas-operated venturi nozzle having mist flow rates ranging from about 0.1 cfm to about 65 cfm. A pressure relief valve for relieving excess gas pressure is also disposed in the mist generating passage and adapted to open if the gas pressure in the mist generating system reaches a predetermined level. The mist generating apparatus further comprises an adjusting member, such as a needle valve, disposed in the liquid inlet passage and extending externally of the frame member to a position accessible for adjustive manipulation by an operator for controlling the liquid flow rate and adjusting the ratio of liquid-to-gas in the mist.

Abstract: An agricultural spray implement includes a plurality of removable valve/filter/nozzle cartridges. Each removable cartridge has a housing that retains a high speed solenoid valve and a spray nozzle. When the solenoid valve is open, an agricultural liquid (for example, herbicide) flows through the solenoid valve, through a chamber in the housing, and through the nozzle. To monitor cartridge operation and/or to detect cartridge failures (for example, a solenoid valve that is stuck open or closed or a nozzle that is clogged), a pressure sensor is provided that detects a pressure in the chamber. A chamber pressure that does not change when the solenoid valve is controlled to open and/or close is indicative of cartridge failure. Operation of each of the many spray cartridges of the agricultural spray implement is monitored from a single display.
