Abstract: A decoy rig 100 is described having a number of individual decoys 102 deployed at intervals along the length of a shaft 104. The decoys 102 are deployed at an angle relative to the shaft 104 axis, and oriented around the shaft 104 diameter similar to the blades of a turbine rotor in relation to a turbine shaft. When driven by natural forces the anchor 110 holds decoy rig 100 in place against water or air flow inducing a differential pressure across the decoys 102 providing the motive force to rotate the decoy rig 100. In operation, the decoy rig 100 floats centered at or near the water surface and is moved by external forces such as wind, water current or tide, or may be mechanically driven thus causing 360 degree revolution movement by the individual decoys 102, effectively simulating the diving and feeding action of the decoy's live counterparts.

Abstract: Beginning with a smooth ground aluminum blank with a relatively thin layer of leveled Ni—P, circumferential electropolishing/texturing is carried out to achieve a smooth oriented surface. A conductive slurry is provided between the disc and a porous texturing tape which is in contact with a conducting plate or equivalent conductor. The disc serves as the anode, and the conducting plate as the cathode, while the slurry, being conductive, functions as an electrolyte. In the presence of current, a reverse electroplating occurs so that the Ni—P dissolves to form Ni2+, or nickel ions which are carried away by the conductive slurry. The conductive slurry further supports or carries therein abrasive material so that by moving the porous texturing tape past the disc surface, the texturing tape picks up the abrasive material in the slurry and simultaneously with the reverse electroplating, provides the desired mechanical abrasion to achieve texturing of the disc surface.

Abstract: A process of retrofitting an existing window that uses a gasket to secure a sacrificial member and a glazing. The sacrificial member forms a replaceable protective barrier between the glazing and occupants of a vehicle such as a bus. The gasket is traditionally used to secure the sacrificial member and the glazing to the window.

The gasket is replaced with a rigid retainer member that fits into an existing recess that receives the gasket. The retainer member secures the sacrificial member and the glazing to the window so as to permit repeated changes of the sacrificial member without removal of the retainer member.

Abstract: The reduction of NOx in diesel engine exhaust gas, typically at about 200° C. to 400° C., is accomplished using a dual bed NaY—CuY zeolite reduction catalyst. The effectiveness of the catalyst in reducing the nitrogen oxides is markedly increased by the separate and sequential additions of plasma reformed diesel fuel and ozone to the exhaust before it contacts the powdered catalyst. Reformed diesel fuel is obtained by withdrawing fuel from on-board storage, heating the withdrawn volume and stripping a more volatile fraction with air and passing the air/volatile diesel fuel fraction through a non-thermal plasma reactor. Ozone is obtained by blowing ambient air through a second non-thermal plasma reactor.

Abstract: A fuel tank body has a double-layer structure composed of an inner tank shell and an outer tank shell, so that an inter-tank-shell space is formed therebetween. Because heat of fuel in the fuel tank body is discharged into the inter-tank-shell space, the temperature of fuel in the fuel tank body is prevented from rising. If the pressure in a canister becomes negative due to a negative pressure in an intake system of an engine, more specifically, a negative pressure in a surge tank leading to an air cleaner, high-temperature air in the inter-tank-shell space between the inner tank shell and the outer tank shell flows into the canister. On the other hand, low-temperature air flows from the air cleaner into the inter-tank-shell space which has become negative in pressure.

Abstract: The use of lime and sodium sulfide in leather making creates a lot of environmental concern. However, there is no commercial beam house process that could totally eliminate the use of lime and sodium sulfide. In this invention, a novel bio-chemical process has been standardized employing specific enzymes and non-toxic chemical that could totally eliminate the use of lime and sodium sulfide in leather processing. It has been found that the extent of hair removal and opening up of fiber bundles is comparable to that of the conventional limed leathers. Performance of the leathers is shown to be on par with conventionally leathers. The process also enjoys reduction in chemical oxygen demand and total solids load compared to conventional process.
