A self-stopping mobile chair system comprising: a chair including a base, a joint and a seat coupled to the base via the joint to allow a movement of the seat relative to the base between a fore position and an aft position; a locking mechanism configurable between: an engageable state in which the locking mechanism locks the seat upon the seat being in a rated position between the fore and aft positions, the seat movable toward the rated position to be locked by the locking mechanism, and a disengaged state in which the seat is movable between the fore and aft positions unhindered; and an actuator connected between the seat and the locking mechanism to configure the locking mechanism either in the disengaged state upon the seat bearing a force or in the engageable state absent the force. There is also provided a movement stopping system for a mobile chair.

A self-locking system comprising a state selector for detecting the intent of an occupant to rise from a chair and then automatically causing a lock to block the mobility functions of the chair. The state detector is responsive to movement of an upper portion of the body of the occupant while the occupant is still supported in a normal seated position on the seat of the chair, thereby advantageously allowing the locking of the mobility functions of the chair to occur before the occupant starts to lift his weight from the seat of the chair.

An automatic device for cutting the legs of pork carcasses laying transversally onto a conveyor. A support carrier is mounted onto a frame extending close to the conveyor in such a manner as to be movable toward and away from the conveyor. The support carrier supports a circular saw extending in a vertical plane parallel to the moving direction of the conveyor at a sufficient height to cut the legs projecting away from the same. The support carrier also supports a device called 'feeler' that is pivotably hung to a horizontal pivot at a predetermined distance from the saw, which corresponds to the average length for the legs to be cut. A control system is operatively connected to a presence sensor mounted in such a manner to detect the legs of the carcasses when these legs reach the feeler. The control system is also connected to a motion detector that detects any swing of the feeler, and to a power jack for moving the support carrier. The control system is actuated as soon as the presence sensor detects a leg, and it operates the power jack in order to move the support carrier towards the conveyor in order to bring this device in contact with the leg if this one is not already in contact with the same, or to move the device in the opposite direction to bring it out of contact with the detected leg if this leg is already in contact with it. Such a generated contact or lack of contact with the legs is detected by the motion detector which gives a signal for stopping the motion of the support carrier and, accordingly, of the saw which is then automatically positioned to cut the detected leg.

An apparatus for transferring while turning upside down a piece of meat such as loins from a supply surface on which the loins are in one position to a receiving conveyor on which a plurality of saddles are mounted at regular intervals to receive the loins in another upside down position. The apparatus has an L-shaped rack for receiving the loins from the supply surface. This rack is pivotable between a stopping position and a delivering position in which its surface acts as an extension of the supply surface on which the loins may slide to reach the saddles. An inverting member is mounted onto the rack and pivotably movable therewith between the stopping and delivering positions. This inverting member is shaped and positioned in such a manner as to extend in the same plane or under the supply surface when the rack is in its stopping position in order to collect the loin that is on the supply surface, and then to cause it to turn upside down onto the receiving surface while the rack is rotating down into its delivering position.
