摘要： A solenoid including a first magnetic core and a second magnetic core defining an air gap between. A displaceable ferromagnetic member is within the air gap. The ferromagnetic member magnetically connects the first magnetic core and the second magnetic core to create a magnetic flux path between them. This flux results in an increased pull between the first magnetic core and the second magnetic core. A solenoid coil surrounds at least one of the first magnetic core and the second magnetic core.

摘要： Self-winding power generating device, system, and method are disclosed. The device includes a mechanical winding knob for receiving mechanical energy from a downhole environment, a gear train including a plurality of gears engaged with each other, wherein a first gear in the gear train is operatively connected to the mechanical winding knob, and configured to receive mechanical energy from the mechanical winding knob and transfer the mechanical energy to a second gear in the gear train, a spiral spring attached to one of the gears in the gear train, the spiral spring configured to self-wind and store the mechanical energy upon receiving the mechanical energy from the first gear, and a power generation unit configured to receive the mechanical energy from a last of the plurality of gears and convert the mechanical energy into electrical energy.

摘要： The dynamic power booster is an apparatus which utilizes rotational input power for driving a crank lever in circular rotation. The crank lever drives a pivotally mounted lever assembly, having a first and a second lever slidably connected with one another, in a reciprocating and oscillating movement.An oscillating arm is movably mounted by its first end portion on the second lever adjacent to the assembly pivot mounting arrangement, and the second end portion of the oscillating arm is attached to one way clutches which are attached to an output shaft.Upon rotation of the crank lever, the combination lever assembly moves into an oscillating and reciprocating motion and simultaneously oscillates the oscillating arm, which in turn via the one way clutches rotates the output shaft.The dynamic power booster increases the output torque with a minimum decrease of the output shaft's rotational speed and simultaneously provides for high starting torque and overload torque features without transmitting these overloads back to the input power source.

摘要： A gear wheel drive air compressor which is constructed as a piston compressor, the drive gear wheel of which on the air compressor crankshaft meshes with a gear wheel on the camshaft of the internal combustion engine. The inventive construction prevents the reverse acceleration of the camshaft drive gear wheel and minimizes the knocking pulse and noise in the mesh of the camshaft gear wheel in that the transmission ratio between the air compressor drive gear wheel and the camshaft gear wheel is embodied as a multiple load cycle of the camshaft drive torque, and at the same time the angular position of the air compressor crankshaft relative to the camshaft is fixed such that negative torque components of the air compressor crankshaft are eliminated by the overlapping of positive torque components of the camshaft. Furthermore, the air compressor drive gear wheel is arranged in alignment with the air compressor crankshaft.

摘要： The invention relates to a spring-actuated mechanism for actuating a switching device or the like, which is characterised by a control cam unit (9) secured on a crankshaft (10a, 10b) and movable by the latter, by cam grooves or recesses (9a) formed in the said unit and having a shape such that the distance from the centre of the crankshaft (10a, 10b) is at its minimum in the central region of the cam recess (9a) and increases progressively towards the ends of the latter, by a rod element (15, 17), which is provided at one end with a pin (14, 16) which can be rolled along in the cam recesses (9a) and is provided at the other end with a spring support (19, 21), by an element (20) fixed to the device and having a guide element (20a) for guiding the rod element (15, 17) with a straight-line movement, and by a spring element (18) which is arranged between the element (20) fixed to the device and the spring support (19 and 21) and, upon rotation of the crankshaft (10a, 10b) by a drive, is capable of storing energy over a predetermined angle and releases the stored energy upon further rotation of the crankshaft in order to accelerate the rotary movement of the crankshaft (10a, 10b).
