An automated window shutter assembly includes a pair of shutters that is each movably positioned on an exterior wall of a building. Each of the shutters is positionable in an open position or a closed position. A housing is coupled to the exterior wall of the building and the housing is positioned above the window. A pair of screws is each rotatably positioned within the housing and each of the screws is rotatable in a closing direction or an opening direction. A drive unit is positioned within the housing and the drive unit engages each of the screws. The drive unit is turned on to rotate each of the screws in the closing direction or the opening direction. A plurality of engagements each threadably engages a respective one of the screws. Each of the engagements is coupled to a respective one of the shutters for opening and closing the shutters.

A hopper door opening and closing apparatus operates a door on a hopper discharge opening. A pair of motorized linear actuators, each having an extendable rod, are mounted to support rails on opposite sides of the door. A bracket connects the rods to the door. A controller selectively activates the linear actuators to extend the rods and thereby move the door to an open position that permits material to flow through the lower opening and selectively activates the linear actuators to retract rods and thereby move the door to a closed position covering the lower opening.

A smart window/door opening-closing device that can easily be installed for use with an existing door or window or can be built-in by the door or window manufacturer, can be programmed to activate the opening or closing of the door or window either (a) remotely, (b) automatically by a pet and/or (c) automatically by a voice command, is easily disengaged when use is not desired, provides safety and security to prevent unwanted opening or closing of the door or window, and is integrated with a wireless communication network to enable smart and remote control of the window/door actuator.

A refuse vehicle includes a chassis, a body assembly coupled to the chassis, an electric energy system, and a door system. The body assembly defines a refuse compartment. The body assembly has a cover that at least partially encloses the refuse compartment such that an opening is defined in the body assembly to provide access to the refuse compartment. The door system is coupled to the cover. The door system includes a panel and an electric actuator powered by the electric energy system. The electric actuator is configured to selectively reposition the panel between a first position where the panel extends across the opening and a second position where the panel does not extend across the opening.

A carrier arrangement of a planetary gear, in particular a planetary gear of a side door drive, includes a planetary carrier, preferably in one-piece, with a flange that extends along a rotational axis (APT) and which is provided with a first side and a second side, at least one planetary wheel, which is retained at a distance from the pivoting axis (APT) and is pivot-mounted around a planetary wheel rotational axis (APR), wherein at least one recess is arranged between the first side and the second side, in which the at least one planetary wheel is pivotally mounted and retained by means of at least one planetary wheel axle, wherein the planetary carrier and the planetary wheel are made of plastic and the planetary wheel axle is made from steel or plastic. The disclosure relates, moreover, to a method for the manufacture of such a planetary carrier arrangement.

The disclosure relates to a door opener to open a door of a cassette with substrates, the opener having a first wall to engage with the cassette and having a first opening to transfer the door and the substrates and a second wall opposite the first wall and having a second opening to transfer substrates. The door opener may have a closure device to hold the door of the cassette and having first and second sides and moveable in a chamber formed between the first and second wall. The opener may have a first actuator to move the closure device in a first direction from a first closing position where the first side closes against the first wall to a second closing position where the second side closes against the second wall, and from the second closing position to a transport position in between the first and second closing positions.

A clutch mechanism for coupling and uncoupling an electric motor and leadscrew has dog-clutch gears that can be engaged by a linear actuator, bell crank, and linkage shaft. Uncoupling force due to narrowed dog teeth are resisted by the alignment of the linkage shaft with the central portion of the bell crank.
