Abstract: A surface-modified solid fertilizer product is produced by preparing a mixture of a modifier, a water-soluble calcium salt, and water. The modifier is desirably a nitrification inhibitor such as dicyanodiamide and the calcium salt is desirably calcium chloride. A solid fertilizer is prepared, preferably in granular form. The fertilizer has a component reactive with calcium to produce a water-insoluble precipitate. The mixture is coated onto the solid fertilizer, and the solid fertilizer having the mixture coated thereon is dried. The calcium salt reacts with the reactive component of the fertilizer to produce an insoluble binding agent that binds the modifier to the surface of the fertilizer particles.

Abstract: A surface of a 3-D object is digitized automatically and stored in a memory. Based on the signal representation of the 3-D object areas of the surface are defined for color and boundaries. Coatings application paths are defined within each area and various parameters for applying coatings for each point in each path are also defined including spray pattern, amount of coatings to be applied, speed of application along the path, among others; for each area, the points of the selected path are correlated with the angle of attack, spray pattern, amount of coatings and speed. A set of programmed instructions are compiled for execution in a general purpose computer. An assembly line of objects to be painted may then be set up and the retrieved instructions executed.

Abstract: A tungsten silicide film is deposited from WF.sub.6 and SiCl.sub.2 H.sub.2 onto a substrate so that the tungsten to silicon ratio is substantially uniform through the thickness of the WSi.sub.x film, and the WSi.sub.x film is substantially free of fluorine. The film can be deposited by a multi-stage process where the pressure in the chamber is varied, or by a high temperature, high pressure deposition process in a plasma cleaned deposition chamber. Preferably the SiCl.sub.2 H.sub.2 and the WF.sub.6 are mixed upstream of the deposition chamber. A seeding gas can be added to the process gases.

Abstract: An apparatus applies dressing fluid to a bowling lane surface in a desired lane dressing pattern laterally across a plurality of zones on the bowling lane and longitudinally along a predetermined length of each of the zones. Each zone may be the width or a selected fractional width of one board across the bowling lane so that different discrete amounts of lane dressing can be applied to each board along a predetermined length. The apparatus includes a plurality of metering devices which supply lane dressing to corresponding lane dressing dispersion units which in turn supply lane dressing directly to an applicator. The applicator applies the lane dressing to the bowling lane according to the desired lane dressing pattern. A method is provided to supply discrete amounts of bowling lane dressing at desired incremental locations laterally across and longitudinally along a bowling lane.

Abstract: A system and a process is provided for reducing the dust formation during the transfer of a particulate material on an endless conveyor belt. During transfer of the material on the conveyor belt the material is first sprayed with a wetting agent then by application of a plow the moving material is lifted from the bottom of the belt and is diverted towards the side edges of the belt thus creating additional exposed surfaces. The material is then again sprayed then contacted with baffles to redirect the material from the side edges towards the center of the belt thus creating additional exposed surfaces which are then again sprayed with a wetting agent to substantially eliminate dusting. The plow and baffle combination can also be used for uniformly mixing two or more particulate materials on a moving belt.

Abstract: A method and apparatus for spray coating a paper or board web in which a coating paste or mix is applied as an aerosol to the web in an enclosed space or chamber. A flow of the coating paste flows down at least one of the interior walls of the enclosed space, thereby collecting excess coating paste aerosol and providing a seal between the web and the walls of the enclosed space. By providing this seal, the amount of excess coating paste aerosol escaping from the enclosed space and the amount of air travelling along the surface of the web are both reduced, thereby increasing the quality of the applied coating.
