  • Patent number: 6186411
    Abstract: A nozzle assembly allows a metered dose of lubricant to be dispensed. It comprises a housing and a piston assembly. The housing defines a piston bore, a stem bore and a spout, all of which axially aligned. It also defines a lubricant passage, an air inlet, and a channel linked to the inlet. Connectable to a source of lubricant, the passage communicates with the stem bore. Connectable to a source of air, the inlet communicates with the stem bore at a position between the passage and spout. The piston assembly has a piston with stem and a spring. The piston lies in the piston bore, its back communicating with the channel. The protrudent end of the stem protrudes into the stem bore and has a groove defined about its circumference. The spring biases the piston assembly into a charge position wherein the groove aligns with the passage. This enables the groove to fill with lubricant.

  • Patent number: 6186360
    Abstract: Disclosed is a machine for unloading a bulk-material bag of the type having a bottom portion, a side portion and a transition portion between the bottom and side portions. The machine includes an apparatus aiding discharge of the material from the bag. In the improvement, the apparatus includes a tri-section panel mounted for movement on the machine, thereby configuring the panel to sequentially contact the bottom, transition and side portions of the bag. The panel has first, second and third segments angle-mounted to one another. In a specific embodiment, the segments are substantially planar. A microprocessor-based controller is coupled to the actuator and regulates its movement as a function of a process parameter, e.g., the compressibility of the bag and/or the weight of the material contained in the bag. A highly preferred embodiment of the machine also has a bag lifting mechanism above the tri-section panel.

  • Patent number: 6158521
    Abstract: A portable fire-fighting container is comprised of a box with a top opening and compartments on its sides. A liquid receptacle is positioned inside the box under the top opening thereof. An interior liner is positioned inside the liquid receptacle. An open top of the liquid receptacle is covered with a removable lid. Sling attachments arranged around the box enable the container to be airlifted by a helicopter. The lid is removed and positioned vertically on top of the box to provide directional stability in flight. When placed at a fire location, leveling jacks around the box provide stability on uneven ground. Trapezoidal frames are hinged along the edges of the top opening of the box. The frames are pivoted upward and supported at an acute angle by braces extending between the frames and the top of the box, thus forming an inverted truncated pyramid.

  • Patent number: 6068200
    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.

  • Patent number: 5961051
    Abstract: A shower apparatus reduces the effects of water hammer within a portion of a flow route connecting a shower head to a supply, when a flow adjusting mechanism proximal the shower head is operated. The shower apparatus adjusts pressure of a supply fluid dependant upon the degree of throttling of the flow route and the flow adjusting mechanism controls the amount of flow of the supply fluid dependant upon a degree of opening thereof to the discharge end of a shower head. The structure providing the pressure adjustment and the flow adjusting mechanism are each disposed successively from upstream of the flow route, between a shower side flow route provided in a water plug and the shower head or a discharge end of the shower head.

  • Patent number: 5927606
    Abstract: A sprayer attachment is designed for mounting upon a swather tractor and includes a central frame with a tank which can be carried upon the front arms of the swather tractor. Two masts each carry a respective one of a pair of booms, each for extending outwardly to a respective side of the tractor for movement with the tractor in a spraying action. Each boom includes an inner section, an outer section and a tip portion. In the folding action the outer section and tip portion are folded about a horizontal axis so as to move to a position overlying the inner section. The folded boom is then pivoted about a vertical axis at the mast to lie along side the side of the tractor. The tip portion includes a parallel cable in advance of the tip portion for impacting an obstacle with the cable actuating release of the latch and accelerating the tip portion away from the obstacle to prevent impact with the obstacle.

  • Patent number: 5904297
    Abstract: A pressurized fluid discharge gun is used to spray high pressure fluid against various types of surfaces for cleaning purposes. To operate the gun two handles, each with a separate trigger, must be firmly held by the operator. When both triggers are compressed firmly towards the handle, highly pressurized fluid exits the gun. If either one of the triggers is released then the fluid is dumped to a low pressure discharge, i.e. high pressure fluid is not permitted to exit the gun. The gun has a high pressure pipe and a low pressure pipe connected to a main body. A valve assembly, located in the main body, controls whether the fluid from the inlet goes to the high pressure pipe or the low pressure pipe. The valve assembly has a high pressure path and a low pressure path interconnected by two passages. Two pin valves, each controlled by one of the triggers, block the two passages when the triggers are compressed resulting in high pressure fluid flow.

  • Patent number: 5890659
    Abstract: A new process in which a valve closing body is produced with a predetermined inclination in relation to a longitudinal tool axis. The valve closing body is set in rotation and thereby carries out a precessing motion so that the tool body that rests against the sealing seat produces a narrow ball zone that always assures a sealing contact between the sealing seat and the valve seat face, even when a valve closing body is guided in the valve with guidance play. The process and the device are particularly suited for machining sealing seats on valve closing bodies of fuel injection valves for fuel injection systems of internal combustion engines.

  • Patent number: 5890653
    Abstract: A fuel injector employs at least one sensing device for sensing changes in the thermodynamic properties of the fuel within the injector to thereby monitor injector performance during usage. In some embodiments, advantageously placed temperature sensors are employed to detect the release of thermal energy which occurs when the potential energy of a fuel at high-pressure is suddenly converted into kinetic energy by lowering the pressure of the fuel. Other embodiments of the instant invention employ advantageously placed pressure sensors to detect sudden changes in fuel pressure which occur during the course of the injection cycle. Whereas the sensing devices of the instant invention can be placed at a variety of locations, they are preferably placed to detect changes in the thermodynamic properties of the fuel flowing within an injector where such changes are appreciably large during injector usage.
