| 20120227519 | Actuating Mechanism for Electric Vehicle Charging System - The general field of invention is electrical connectors and their actuating mechanism. This invention teaches a novel mechanism for mating two parts of a register-free electrical connector.

The dynamic balance rotary block and the adjacent circular slider are fixed together. By means of proper selection of a mounting place and a mass of the dynamic balance rotary block, the mechanism can convert reciprocating inertia of the reciprocating element into rotation inertia so as to obtain a balancing effect. An internal combustion engine and a compressor may be equipped with the crank circular slider mechanism. | 06-27-2013 |

Each piston drives, via a crankshaft, a toothed disk which is attached on the crankshaft. The two toothed disks are coupled to one another with regard to their rotational movement, or the toothed disks that are attached to the two crankshafts are in meshing engagement with one another. The crankshafts are driven by the pistons to produce a rotational movement in opposite directions. The toothed disks have the same diameter and are in direct engagement with one another by way of teeth which are arranged or formed along their circumference. | 08-29-2013 |

| 20140165750 | PROPULSION DEVICE FOR USE WITH A FLUID - In one embodiment, a propulsion device for use in a fluid may include a crank-slider mechanism having one or more cranks, one or more connecting rods, a mast, and one or more slide structures. These structures may be arranged so that rotational motion of the shaft is translated to a combination of substantially linear motion of the mast, between an inner extent and an outer extent, and rotational motion of the mast, within an angular range between a first limit and a second limit. A flexible foil may be rigidly coupled to the mast of the crank-slider mechanism. The flexible foil may include a flexible nose portion and a flexible tail portion. The flexible tail portion may have a differing amount of flexibility than the flexible nose portion. | 06-19-2014 |
| 20140216185 | VARIABLE LINEAR MOTOR - Device and method for enabling independent tuning of frequency and amplitude of a reverse crankshaft motor. The reverse crankshaft motor provides periodic reciprocating motion based on periodic rotational motion from a rotational motor. The reverse crankshaft motor includes a crankshaft structure having first and second frames with a third axle arranged between them and connected to them by hinges. An amplituder is affixed to the third axle and may communicate with an external device. As the first and second frames move toward or apart from each other, the third axle moves radially toward or away from a central axis of the crankshaft structure. The position of the third axle determines the amplitude of the periodic reciprocating motion of the amplituder. By adjusting the position of the first and second frames, the operator may adjust the amplitude independently from the frequency of the periodic rotational motion supplied by the rotational motor. | 08-07-2014 |
