Abstract: A spreader for particulate material, the spreader being of the broadcast type having a hopper from which particulate material is discharged onto a rotating impeller. To provide adjustment for materials of various physical properties, a conically-shaped deflector is mounted between the hopper and impeller. The deflector is helically shaped at the bottom so that it has a gradually varying radius. By rotary adjustment of the deflector, particulate material can be discharged onto a preselected portion of the impeller.

Abstract: A rotary spreader for particulate material having a hopper for the particulate material and an impeller adapted to broadcast the material as it is discharged from the hopper. The impeller has a ridge enclosing the central portion of the impeller and the impeller is mounted in close proximity to the hopper so that discharged material is contained within the enclosed central portion of the impeller to stop further flow of particulate material when the impeller is not rotating.

Abstract: A hole cutter for plastic tubing comprising a pair of opposed members pivotally joined at one end thereof, means between said opposed members for limiting their separation in open position, recesses within the opposed members for gripping a tube and a hollow cylindrical blade rotatably mounted on one of the opposed members, adapted upon rotation to cut a hole in a tube gripped in the cutter.

Abstract: A process for preparing a slurry structured metal composition comprising degenerate dendritic solid particles contained within a lower melting matrix composition, the process comprising vigorously agitating at a given shear rate molten metal as it is solidified. Greatly improved processing efficiencies result if the shear and solidification rates are adjusted so that the ratio of the shear rate to the solidification rate is maintained at a value ranging from 2.times.10.sup.3 to 8.times.10.sup.3.

Abstract: A timed water shut-off device of the type primarily useful for home gardens and lawns. The device comprises a water conduit containing a ball valve, a timer and timer housing rotatably mounted on the conduit and a plunger directly linking the timer and ball valve to permit flow of water for a preselected time.

Abstract: A paint composition for inhibiting corrosion of a metal surface includes a powdered sacrificial metal for that surface and a powdered water soluble corrosion inhibiting glass. Typically the paint is a zinc rich paint and the glass is a calcium/zinc phosphate glass.

Abstract: A process and apparatus for the continuous production of shaped aluminum alloy-particulate composites. The process comprises metering at a substantially constant ratio a particulate solid molten aluminum alloy containing at least 0.10% by weight of magnesium into a mixing station while continuously vigorously agitating to produce a homogeneous mixture, simultaneously discharging from the mixing station a homogeneous mixture of molten aluminum alloy and particulate solid, transferring the mixture to a forming station and shaping and solidifying the composite.

Abstract: A method for making the light-sensitive layer of a GaInAsP photodetector for the wavelength range from about 1350 nm to 1400 nm by liquid-phase epitaxy. A melt is saturated with phosphorus by introducing a first InP substrate into a ternary solution of GaAs and InAs in indium and maintaining the temperature constant at about 690.degree. C. for a few hours. After removal of the first substrate, the temperature is lowered by about 5.degree. C., and a second InP substrate, on which the desired layer is grown, is introduced into the melt. The cooling rate is approximately 1.degree. C./hr.

Abstract: A formulation for the reduction of amine and ammonia odors of organic waste material comprising spent sulfite liquor containing substantially undegraded lignosulfonates and sugars, to which is added from 1 to 15%, by weight of the total solids content, of acetic acid and from 0.5 to 10 grams, per liter of formulation, of phenolic carbonyl compounds, the formulation having a pH of from 6.5 to 8.0 and preferably having being stripped of dissolved SO.sub.2.

Abstract: A rotary sprinkler of the impact type having a manually settable mechanism for both selecting and displaying an overall pattern configuration of sprinkler stream coverage. The manually settable mechanism comprises two concentric abutting surfaces, one being rotatable and the other being fixed relative to the sprinkler stem. The surfaces in combination indicate the pattern configuration. The rotatable surface includes a cam which engages a first or a second cam follower on a water stream deflector assembly to provide a first or a second patterned configuration of sprinkler stream coverage.
