摘要： A latching mechanism comprises an energy storage system having a first closing spring, and a second opening and earthing spring, arranged between a transmission device and a closing control crankshaft and an earthing crank. A retaining plate pivoting on an axis cooperates on the one hand with an opening control lock by means of a unidirectional locking and on the other hand with the crankshaft by means of two latchings. The first latching is released during the opening travel after the lock has been unlocked, and the second latching causes positive locking of the device at the beginning of the closing travel of the crankshaft.

摘要： A multi-position automatic switching actuator for a load switch includes an oil pressure cylinder member operated by power, a latch releasing member rotating in accordance with the operation of the oil pressure cylinder member, a latch member fixedly engaged to the latch releasing member and rotating in accordance with the rotation of the latch releasing member, a latch stopping member connected to the latch member and limiting the rotation of the latch member by a predetermined angle, an elastic member disposed between the latch releasing member and the latch member for instantly rotating the latch member, and a central shaft inserted through the latch member. The actuator appropriately switches a contact position to another and carries out a multi-position switching control by employing a single actuator, thereby simplifying production, decreasing production cost, and securing safety in work operations.

摘要： An operating mechanism that provides multiple operational output states at a first output and additional operational output states at a second output that are synchronized with the first output to provide a predetermined sequence of control. The operating mechanism includes an output lever that is pivoted by the stored energy in a spring and latch levers that are selectively operated to release the output lever. When the output lever is moved between operational positions, the output lever is stopped in its pivoting movement via the latch levers.

摘要： An operating mechanism of a three-position switch having a contact-bearing main shaft comprises a switch closing and opening operation device, and an earthing device closing and opening operating device. The two devices comprise driving flange plates connected by a common spring capable of being loaded by rotation of either of the operating shafts and transmitting, after the deadpoint has been reached, a drive movement of these flange plates transmitted by articulated levers to a crank handle wedged onto the main shaft. All the operations are high-speed and the torque transmitted to the main shaft increases in the course of the operating movement. A locking device maintains the main shaft in the open position during the loading phase of the spring.

摘要： A pneumatic brace comprising at least one outer shell member and at least first and second pressurizable chambers juxtaposed therewith in an overlapping manner for providing a supporting cushion between said outer shell member and a body part or limb. One of said chambers is coextensive with substantially the entire inner surface of said one outer shell member for engagement with a corresponding portion of said body part or limb, while the other of said chambers is coextensive with a portion of said first chamber. In one preferred embodiment, the first and second chambers comprise separate inflatable airbags of different size disposed on said outer shell member with the smaller airbag positioned coextensively with the bottom portion of the larger airbag and between said larger airbag and said inner surface of said outer shell member. In alternatively preferred embodiments, the first and second chambers are integrally formed from a single inflatable liner having two compartments divided by a common wall, at least one of said compartments being selectively inflatable through integral valve means formed at least in part by said common wall.

摘要： An actuating mechanism of a three-position switch, the switch comprising a main shaft supporting or actuating contacts and able to be moved selectively to three stable positions and a center crank which is pivotally mounted and can be actuated so as to take the three positions of the main shaft, the mechanism in addition having a mechanical system which produces a kinetic ratio between the angular movement of the center crank and that of the main shaft which increases when the center crank moves from the open position to the closed position, which results in the force transmitted to the electrical contacts increasing continuously as movement takes place from the open position to the closed position.
