Abstract: A method for cleaning and protecting a diesel cooling system from corrosion and the effects of the corrosive by-products wherein a filter is used to feed a dissolvable pellet comprising dissolvable cleaning agents and corrosion inhibiting agents into the cooling system. The cleaner consists of chelating agents, surfactants, and anti-foaming agents. The filter is removably inserted in the cooling system, and the cleaners and inhibitors dissolve in the coolant to clean and protectively coat the cooling system while the engine is operating. The removed impurities are captured by the filter and the filter is replaced within a few weeks with a standard filter containing inhibiting agents. The method thus does not require draining the cooling system to clean the cooling system.

Abstract: The pulse wave of the ordinary period is admitted to the input terminal(A,C) of the signal pulse, and the pulse wave of the inverse period is admitted to the input terminal(B,D) of the signal pulse. If the high signal is admitted to the input terminal(A,C) of the signal pulse, the output of the input reversal part(10) is low and RS flipflop(FF1,FF2) of the ratch circuit(20) is reset. At this time, if the overvoltage is generated, the current trans of the AC input terminal admits the high pulse to the input terminal(F) of the signal pulse by detecting the maximum voltage of the over current and impresses the high pulse in the input terminal of the end gate(31) by setting the RS flipflop(FF3,FF4). Next, the high signal is output from the trigger pulse terminal(Ap), and it is input into the driving part(40). Subsequently, the gate of triac is triggered by making the photo coupler(PC1) operate through the diode(D3).

The drive member (32) has an internal passageway (62) formed therein for feeding the lubricant to the clutch member. The passageway has a section which is radially spaced from the axis of rotation and has a seat (72) formed therein for cooperating with a rotationally speed sensitive valve (74) oriented in the first passageway. Below a first rotational speed, the lubricant pressure maintains the valve against the seat restricting the flow of lubricant to the clutch element. When the driven member is rotated above the first rotational speed. Centrifugal force biases the valve off the seat, allowing lubricant to be supplied to the clutch element. Preferably, a second lubrication passageway (76) is provided having a seat in an internal valve which selectively supplies a lubricant to the clutch element at a second higher rotational speed. In order to further reduce disengaged clutch drag at idle, a speed sensitive piston retract spring (58) is provided to increase piston travel at low engine speeds while maintaining minimum travel at off idle operation.

Title: Multistoreyed parking for crowdy areas
Inventor: RO CA VASILE
IPC: E04H6/12
Filed: 2005-06-17
Abstract: The invention relates to a multistoreyed parking meant for crowdy urban areas, having an integrally prefabricated cylindrical structure, which may be located in areas where there is not enough space for classical parkings, next to institutions or private firms. The multistoreyed parking for crowdy areas has a cylindrical shape and, on each floor comprises compartments, arranged arround a central well, made as a prefabricated structure, provided with computer for the total access control of entrances, exits and maneouvres. The structure consists of prefabricated cup-like foundations (1) arranged on two concentric circles, wherein there are mounted and all-cast carried out two rows of prefabricated poles, of which a row of interior poles (3) which form an interior central well, and a row of exterior poles (4), the poles being provided, at each level, with brackets whereon there are mounted some prefabricated girders (5) with T-section. On the brackets there are mounted some circle rim-type slabs (6), which form a floor at each level, inside the central interior well there being provided a central tank (2), whereon there is mounted a hydraulic telescopic arm (8) whichon there is supported a rotary double metal platform (9), guided in relation to the well, with which there are lifted, descended and placed, by computer means the cars in the free compartments. The hydraulic telescopic arm (8) is fastened by pins in the central tank (2), wherein it is folded or extended for lifting and descending the double platform (9), being actuated by a double flow hydraulic pump (26).

Title: System for regulating the speed of a wind generator to variable wind speed with self-braking
Inventor: CRISTEA GHEORGHE
IPC: F03D3/00
Filed: 2006-05-30
Abstract: The invention relates to a system for regulating the speed of a wind generator to the wind speed with self-braking, meant to be used as a main subassembly in wind turbines playing the role of converting the mechanical energy taken over from the propeller into electric current. According to the invention, the system has a grooved axle (1) whereon a rotor (2) is mounted, said rotor being provided with permanent magnets (3), some spacing bushings (4 and 5), a compression spring (6) with the role of bringing the rotor (2) to the initial position, and a centrifugal subassembly for the varying an air gap (delta), comprising some bushes (7 and 8), some rods (9) and a shaft (10), assembled to one another by means of some bearings (11) and also some flanges (12 and 13) whereon some wound stators (14) are mounted, which are located on the grooved axle (1) by means of radial bearings (16) and are mounted in a housing (17) by means of some studs (18) and nuts (19).
