Title: Decorative light with a changeable shade
Inventor: XU FEI
IPC: F21S4/10
Filed: 2011-08-29
Granted: 2013-11-19
Abstract: A decorative light includes a light source (10), two wires (20), a socket (30) and a shade (40). The wires (20) have top ends electrically connected to a bottom of the light source (10) by welding. The socket (30) is coated around the bottom of the light source (10) and the top ends of the wires (20) by injection molding. The shade (40) covers the light source (10) and is detachably mounted on the socket (30). The decorative light can provide a good waterproof effect because the socket (30) seals an opening of the shade (40) to prevent water from infiltrating inside the shade and damaging the light source (10). Besides, users can change shades (40) having different shapes freely to make the decorative light attractive and interesting.

Abstract: Chlorous acid is generated from a chlorite salt precursor, a chlorate salt precursor, or a combination of both by ion exchange. The ion exchange material facilitates the generation of chlorous acid by simultaneously removing unwanted cations from solution and adding hydrogen ion to solution. Chlorine dioxide is generated in a controlled manner from chlorous acid by catalysis. Chlorine dioxide can be generated either subsequent to the generation of chlorous acid or simultaneously with the generation of chlorous acid. For catalysis of chlorous acid to chlorine dioxide, the chlorous acid may be generated by ion exchange or in a conventional manner. Ion exchange materials are also used to purify the chlorous acid and chlorine dioxide solutions, without causing degradation of said solutions, to exchange undesirable ions in the chlorous acid and chlorine dioxide solutions with desirable ions, such as stabilizing ions, and to adjust the pH of chlorous acid and chlorine dioxide solutions.

Abstract: In some variations, this disclosure provides a method of verifying the presence of an admixture in association with a solid base material, by combining the admixture with a stable inorganic tracer. A sample of the solid base material may be analyzed, using suitable analytical techniques, to detect the presence of the inorganic tracer in excess of any native inorganic tracer. When the inorganic tracer is positively detected, it is confirmed that the traceable admixture has been properly dosed within the base material. The inorganic tracer may comprise a rare earth metal, such as selenium, molybdenum, bismuth, and combinations, alloys, or oxides thereof, for example. The solid base material may be a cementitious material, in some embodiments. The traceable admixture may be a water-repellent admixture, in some embodiments.

Abstract: The method for preparing a homogeneous biodegradable mixture is described for production of shape-bodies. Reinforce fillers are fibers from various natural sources especially those wastes from varieties of manufacturing. Long thin fibers are obtained by longitudinal abrasion of bamboo waste. Boiling the fibers in water for 20 minutes at pH 8 where supernatant is decanted helps getting rid of chlorophyll. Fibers are further ground to preferable length of 2-4 mm. The treated fibers were mixed with all other ingredients in a rotor, spinning at a speed 1,800-2,000 rpm at ambient temperature for 5-10 minutes. Starch particles and other ingredients penetrate and mix thoroughly with the fibrous materials. Water is gradually added while kneading to form a perfect dough ready for manufacturing of the desired shape bodies.

Abstract: Unique engines, air compressors, and pneumatically driven electrical generators are disclosed. The engine employs a rotor having a number of pistons slidably disposed within respective cylinder bores extending into the rotor periphery. As the rotor spins within a stator, each cylinder bore passes a combustion stage at which the piston is driven further into the rotor toward a bottom of the respective cylinder bore. Valves at the bottom of the cylinder discharge air that is compressed by this piston downstroke, and admit new intake air during an opposing upstroke. The unit thus operates as a self driven compressor, or engine-compressor combination, and the compressed air may be used to pneumatically drive a turbine of an electrical generator. A carbon splitter dissociates carbon and oxygen molecules from the carbon dioxide in the air downstream of the generator turbine, reducing the overall carbon dioxide output of the system.
