An automatic fire door closing device includes a hydraulic main engine, an arm rod, a rotating shaft, a connecting plate and a clamping device, and further comprises a fire monitoring and response device and a driving device. The driving device includes a linkage rod rotatably connected to the connecting plate, a transmission column rotatably connected to the connecting plate, and a transmission rod fixedly connected to the transmission column, one end of the linkage rod has a hook part for hooking the transmission rod, and the transmission column cooperates with the clamping device, when smoke or open fire is monitored, the hook part of the linkage rod is disengaged from the transmission rod, and the rotation of the transmission column makes the clamping device to release the rotating shaft. The device reduces cost with simple structure, high integration and low installation difficulty.

An emergency vehicle door opening system includes a vehicle assembly with a body having an opening therein to allow passenger entry. The opening has a front edge, a rear edge, a top edge, and a bottom edge. A door is pivotally coupled to the body adjacent to the front edge and is positionable in a closed position closing the opening or in an open position exposing the opening. The door has an inner edge positioned adjacent to the front edge and an outer edge positioned opposite of the inner edge. An opening assembly is mounted on the vehicle assembly. The opening assembly is mounted on the vehicle and moves the door from an ajar position to a fully open position when the opening assembly is actuated. The outer edge of the door moves at a speed greater than 30 mph when the opening assembly moves the door.

An article of manufacture for use as an insulated overhead door that is designed to roll open and closed in tracks, with a sheet of thermoplasitc material that acts as the outer door membrane and barrier to entry, a sheet of insulating material that acts as a base insulating barrier adhered to the thermoplastic membrane.

A vehicle pop-up hood device includes a pair of actuators that move a front hood from a closed position to a lifted position, and a single hood lock device that is disposed at a vehicle width direction intermediate portion between the pair of actuators, that includes an anchor recess to which a hood striker is anchored, and a latch, and that is configured so as to be capable of moving from the closed position to the lifted position together with the front hood. The vehicle pop-up hood device further includes a fixing device that fixes the hood lock device in the closed position; and a fixing release device that releases the fixing of the hood lock device by the fixing device in conjunction with actuation of the actuators.

A linear actuator includes a jacket defining an axis, and a rod having an end cylinder tightly slidable within the jacket and an opposite end sliding between a rest position and a working position. The end cylinder divides the jacket into a first and second variable volume compartment fluidically independent from each other, one of the first or second variable volume compartment being fluidically insulated and under vacuum, the other one fluidly communicating with the outside environment. The jacket has an abutment member having a non-return valve mechanism adapted to discharge ambient air that may be entrapped between the end cylinder and the abutment member.

The invention relates to a covering device for a tool deposition station. The covering device includes a covering as well as a mechanism for moving the covering. The mechanism for moving the covering includes a rail and a first driver which is guided by the rail. The first driver is displaceable along the rail and is connected to the covering. The covering device can be brought into an opened position by way of a displacing of the first driver along the rail in a first direction and the covering device can be brought into a covered position by way of a displacing the first driver along the rail in a second direction which is opposite to the first direction. The mechanism is configured such that the displacing of the first driver effects at least a partial translatory movement of the covering.
