International Classification:

C22C 21/10

US Classification:

148417, 420532

Abstract:

Aluminum alloy products, such as plate, forgings and extrusions, suitable for use in making aerospace structural components like integral wing spars, ribs and webs, comprises about: 6 to 10 wt. % Zn; 1. 2 to 1. 9 wt. % Mg; 1. 2 to 2. 2 wt. % Cu, with Mg≦(Cu+0. 3); and 0. 05 to 0. 4 wt. % Zr, the balance Al, incidental elements and impurities. Preferably, the alloy contains about 6. 9 to 8. 5 wt. % Zn; 1. 2 to 1. 7 wt. % Mg; 1. 3 to 2 wt. % Cu. This alloy provides improved combinations of strength and fracture toughness in thick gauges. When artificially aged per the 3-stage method of preferred embodiments, this alloy also achieves superior SCC performance, including under seacoast conditions.

Appl. No.:

11/442787

Inventors:

John Yuming Liu - Fresh Meadows NY, US

International Classification:

F24H 3/00

US Classification:

237 70

Abstract:

Design the device Steam baseboard to use for steam heating. Water is not easy to get out and water creates the noise and does not easy to get out of the system. Water prevents the heating. We convert the hot water heating baseboard to steam baseboard by using the John's pipe and John's effect.

Appl. No.:

11/588153

Inventors:

John Yuming Liu - Fresh Meadows NY, US

International Classification:

F22B 1/18

US Classification:

122 7 R

Abstract:

Condenser will create a lot of heat from compressor and exhaust heat has to be removed from it. This exhaust heat can be recovered to store in the hot water tank. More important the heat generated by freezer, air conditioner and refrigerator has to be removed either store in the hot water tank or dissipated by baseboard. We design this method to accomplish this goal. We use water to dissipate the heat and we do not waste the water. Water is very expensive about $5.00 per hundred cubic feet. This method will save fuel to pre-warm the water for hot water tank.

International Classification:

B60R 27/00

US Classification:

296200

Abstract:

This invention is to replace any mechanical wind wiper for a vehicle operation. We construct the air pump to blow the air to push the debris, rain water, and snow away from the windows. The pneumatic windshield clearing system includes an air source from engine assembly or and muffler coupled with vehicle, a metal pipes with small holes to have the high pressure pushed air from the top, bottom and side of windshield toward the surface of the windshield.

Inventors:

John Yuming Liu - Fresh Meadows NY, US

International Classification:

A62D 3/00

US Classification:

588300, 588405

Abstract:

It is a system to absorb the CO2 and release the oxygen (O2). We construct the mechanical and electrical instrument. We use solar panel to produce electrical power in DC. We add DC motors attached with rechargeable battery and solar panel. The motor will generate the current and bubbles to make air contact with sea water with dead zone in ocean (desert in ocean). We define the module which is independent platform will have the solar panel, rechargeable battery, 12 or 24 voltage, dc motor, anchor and current guide, bubbles generator. By this platform we can perform the photosynthesis to diminish CO2 and release the oxygen (O2). We can build many platforms to diminish CO2 and we are able to control global warming. We also establish the communication center to locate the position of the platforms. The fish farmland is created through the plankton which is created by the motion of the motor,
