The present invention relates to street sweeper. According to a first aspect of the invention, different mechanisms are disclosed for controlling the movement of the brush-holder arms in a horizontal plane, while also damping side and front impacts. According to a second aspect, a sweeper is disclosed, in which the movement of the brush-holder arms (3) in a vertical plane is imparted by a set of four profile members, arranged in two pairs which each forms a deformable parallelogram, wherein the deformation of the parallelogram is actuated by a jack (25) and the own weight of the sweeping arm. The jack is configured to remain below the upper profile members (11) of the two pairs when the brush-holder arm is raised to its maximum height. According to a third aspect, the suction turbine (103) is arranged in such a way that load losses are reduced during the operation of the sweeper.

To provide an expansion device and a movable body including a mechanism for quick deformation. An expansion device includes a main body and a limb portion attached to the main body, in which the limb portion includes a main link connected to the main body via a joint, an end link provided at a front end of the limb portion, at least one or more limb joints that are interposed between the main link and the end link and connect the main link and the end link, and a linear member of which both ends couple an end at the front end side of the limb portion of the end link and the main body and are retractable to one or both of the end link and the main body.

An endoscope cleansing accessory is described for use with an automatic endoscope reprocessing (AER) apparatus which utilizes the motive force provided by a flowing cleansing fluid already within the AER to actuate an actuator wheel of the endoscope during the cleansing process. The movement or actuation of the actuator wheel during cleansing in turn imparts a back and forth motion to an elevator platform or forceps raiser within the endoscope to loosen tissue and other particles that are then flushed out by the flowing cleansing fluid.

An actuator system can be used to adjust a position of a component in a spatial light modulator. The actuator system has a pair of actuators that are coupled together by a frame that is used to adjust the height of the component relative to the substrate. The frame includes a pair of moment arms that are coupled to the actuators and a pair of connecting arms that are coupled to the moment arms. The connecting arms are then connected together at about the center of the frame, which portion of the frame can be used to raise or lower the plate. The center of the frame can be raised or lowered by a shortening or lengthening of the connecting arms relative to each other.

The present invention relates to an actuator (9)-lever (11) assembly for a sealing device (1) for a motor vehicle front face air inlet, said assembly comprising: an actuator (9) comprising two rotary output members (90) having a hollow (91) and each being arranged on a face of said actuator (9) and on the same pivot axis (C), and in each rotary output member (90), a lever (11) having a stub (110) inserted in the hollow (91) and linked to said rotary output member (90) such as to be driven in rotation by the rotation of said rotary output members (90),
the hollows (91) of the rotary output members (90) being linked to one another by a communication orifice (92) and the levers (11) being attached to one another through said communication orifice (91).

A liftable hinge mechanism includes a base, a connecting component and a pin. The base has a narrow slot. The connecting component has an axle hole. The pin slidably passes through the narrow slot and rotatably inserts into the axle hole. The connecting component can be rotated and/or shifted relative to the base via the pin. A reciprocating engaging mechanism includes a shaft, a rotary plate, a first engaging component and a linkage module. The rotary plate is rotatably disposed on the shaft. The linkage module is connected between the rotary plate and the first engaging component. Rotation of the rotary plate drives the linkage module to move the first engaging component into a locking mode or an unlocking mode. The liftable hinge mechanism and the reciprocating engaging mechanism are applied to an airtight device with a housing and a cover capable of being folded and unfolded.
