  • Patent number: 4552171
    Abstract: A supply conduit mounting assembly is disclosed for a single lever faucet. In assembled condition, the hot and cold water supply conduits are connected to the valve body of the faucet and rigidly held from movement relative to the valve body by a plate which serves as a structural member for mounting the valve body and connecting the end sections of the supply conduits to the valve body without threaded fittings or brazing. Resilient O-rings associated with the ends of the supply conduits provide a water-tight seal adjacent the junction of the supply conduits and the valve body bores and thereby prevent water from coming into contact with the mounting plate, which may be a low cost die casting of metal which is not required to be corrosion resistant.

  • Patent number: 4550518
    Abstract: A fishing decoy made up of thin sheets of transparent material with a plurality of inflatable fish images projected thereon, for the purpose of attracting fish to a particular fishing area. The transparent sheets carry a plurality of fish images in color, with a pictorial of seaweed and the like surrounding the fish images so that they appear to be swimming in their natural habitat. The transparent sheets have an air flotation chamber extending along the upper edge and a series of weights attached along the lower edge to maintain the sheet in a substantially vertical plane. Wave action and other external forces cause a rippling action in the sheets giving the fish images the appearance of swimming and a more life-like appearance.

  • Patent number: 4540124
    Abstract: A rotary disc atomizer adapted to generate relatively precisely controlled, uniformly sized spray droplets whether mounted in a vertical position or in significantly tilted positions. The atomizer includes a power driven rotary disc having a tapered fluid dispensing surface, a liquid supply whirl chamber in coaxial relation to the disc, and a liquid feed arrangement adapted to tangentially feed liquid into the whirl chamber so that it is rapidly moved in a relatively uniform thin sheet about the chamber and then exits in an annular uniform flow centrally onto the dispensing surface of the disc. The centrifical forces of the swirling feed liquid permit the atomizer to be mounted in substantially tilted positions without effecting the uniformity of the spray output or droplet size.

  • Patent number: 4537608
    Abstract: A system for removing contaminant particles from a gas such as air includes an assembly of vortex air cleaners and a depth filter which are disposed in series in a passage through which the air flows so that the larger particles and liquid droplets are removed from the air by the cleaners and the finer particles and finely divided liquid particles are removed by the filter. The vortex air cleaners are arranged side by side in two perpendicular rows and the direction of the rotational flow imparted by each is of the opposite hand from the direction of flow imparted by each adjacent cleaner so that, in the regions where the flows from two adjacent cleaners interact, the flow vectors from the two cleaners are in the same direction. This maintains the rotational flows as the air travels to and enters the filter with the result that plugging of the upstream side of the filter is virtually eliminated and the full depth of the filter is effectively utilized.

  • Patent number: 4534290
    Abstract: An ink dispensing system for a printing press having an ink trough of a fountain roller and comprising a plurality of radially oriented ink spreader assemblies arranged closely side-by-side to form a substantially continuous metering edge for zonal metering of a film of ink on the fountain roller as it rotates. Each printer assembly includes a bearing member and a dispensing member, the bearing member having a tip of narrow dimension and the dispensing member having a film-forming edge. Each bearing member is biased so that its tip rides in contact with the surface of the roller to establish a positional reference for adjustment of the dispensing member. An adjusting screw mounted on the bearing member and engaging the dispensing member is adapted to retract the dispensing member a small distance rearwardly of the tip of the bearing member to thereby determine the zonal thickness of the ink film formed on the surface of the roller by the dispensing member.

  • Patent number: 4532951
    Abstract: An electrical-pneumatic transducer includes a pneumatic relay in which the pressure of the air at the outlet varies in accordance with the back pressure of the air at a bleed nozzle in the relay. This back pressure is changed by the armature of a solenoid with the armature opposing the nozzle outlet and being urged toward the latter with a force responsive to a signal in the form of current flowing through the solenoid coil. The magnitude of the current is correlated with the magnitude of a variable condition. The force on the armature, which is a permanent magnet, is selectively set to calibrate the transducer by means of a second permanent magnet which is axially aligned with the armature and is adjustably movable toward and away from the latter.

  • Patent number: 4531985
    Abstract: A metal ring of generally rectangular cross-section has its radially outer surface and its side surfaces treated by being stacked with its sides in contact with other rings in a chamber. Air is excluded from the chamber and a gaseous mixture of a carburizing gas and a nitrogenous gas at a temperature of 450.degree. C. to 650.degree. C. is supplied to the chamber. The proportions (% by volume) of the gases is between 25:75 and 75:25. The mixture nitro-carburizes both the radially outer surface of the stacked rings and the sides of the ring. If the rings are finish machined before treatment, they are ready for use as soon as they are removed from the chamber. The nitro-carburizing treatment reduces wear on the treated surfaces. The rings are used as piston rings or sealing rings.
