Title: Cooling the Solar cells using saline water and vapor recovery
Inventor: SUBHI AHMAD MAHMOUD AL SALEH
IPC: C25B1/04
Filed: 2017-10-18
Granted: 2020-07-05
Abstract: Solar cells are used to generate electricity from solar energy. The efficiency of cells is inversely affected by high cell temperature. Therefore, a series of water, air and evaporative cooling systems were studied. These systems succeeded in cooling the solar cells and raising the efficiency of generating electricity, but at the end was not economically feasible. Therefore, we offer an innovative cell cooling system capable of effectively increasing power generation in addition to increasing economic feasibility The cooling process in the proposed system, which uses saline or brackish water, is achieved by fixing the solar panel at the top surface of the heat exchanger. When the sun starts to heat the solar panels, cooling water absorbs heat energy and turns part of it into vapor which ascend and condense to produce potable water.. The proposed system is able to reduce the temperature of the cell about 20 degrees Celsius. This raises the efficiency by 10% and the system is capable of producing 10 liters of potable water / m2 / day.

Title: Device for converting linear motion to rotary motion or vice versa
Inventor: BRACKETT DOUGLUS C
IPC: F16H21/18
Filed: 1986-05-12
Granted: 1994-04-06
Abstract: A device for converting linear motion to rotary motion or vice versa employs at least two bearing members mounted for rotation about a crankpin of a rotatable crank, each bearing member being in constant engagement with its own individual bearing surface. A shuttle, which is mounted for reciprocating linear movement, carries the bearing surfaces, which are located on opposite sides of the crankpin and are offset relative to each other. Because the bearing members are in constant engagement with their associated bearing surfaces, the linear motion of the shuttle is continuously converted into the rotary motion of the crank or vice versa.

Inventor: HENRI DUFFOUR
IPC: H01H71/50
Filed: 1988-07-22
Granted: 1997-03-27
Abstract: A release mechanism for a high speed circuit breaker comprises a roller rotatably supported on an axle in a mobile contact bridge. A jack is acting in the circuit closing direction on the roller, and the frontal side of the jack is in the form of a slide. The force of a disconnecting spring acts on the contact bridge in a disconnecting direction. The release mechanism to be provided with the connected contact bridge is capable of very rapid release, so that high short circuit currents may be interrupted very rapidly. This is obtained by the slide having a configuration such that in the connected state of the contact bridge the frictional forces acting on the roller are compensated.
