An item of seating furniture having a seat and a backrest which are supported in an articulated manner on a frame, and having an operating mechanism for adjusting the inclination of the seat and the backrest. The backrest has a catch member and, when the backrest is inclined from a front position into an inclined rear position, the catch member comes into operative contact with the seat as of a specific angle of inclination of the backrest in such a manner that further inclination of the backrest brings about a simultaneous adjustment of the seat. The backrest is adjustable independently of the seat from the front position up to the specific angle of inclination at which the catch member comes into operative contact with the seat.

The invention discloses an underwater towing body controlled by a front-edge-rotating cylindrical wing. Forced sinking hydrofoils of the underwater towing body adopt symmetrical airfoil profiles, andare symmetrically arranged on the two sides of the front portion of a main cavity, two rotating cylinders are symmetrically arranged at the front ends of the profile faces of the forced sinking hydrofoils relative to the main cavity, and are connected with a speed adjusting motor located inside the main cavity through rotating-cylinder rotating shafts; ducted propellers are symmetrically arrangedon the two sides of the back ends of the forced sinking hydrofoils; a transverse horizontal fixed empennage is arranged at the tai lend of the main cavity, and vertical streamlined flap type rudders are symmetrically arranged at the two ends of the transverse horizontal fixed empennage respectively; a flap is arranged at the tail end of each vertical streamlined flap type rudder, and is connectedwith a flap angle control device. According to the underwater towing body controlled by the front-edge-rotating cylindrical wing, by changing the rotating speeds and the rotating directions of the rotating cylinders at the front ends of the forced sinking hydrofoils, attack angles of the forced sinking hydrofoils can be efficiently and flexibly adjusted, and the aim of changing the motion trail ofthe vertical direction of the towing body is achieved; on this basis, the thrust directions of two-side propellers are changed through assisting, and directional floating and sinking can be achieved.

The movable contact is matched with the corrugated pipe. The other end of the insulated pull rod is connected with the permanent magnet operating mechanism. The three-phase permanent operating mechanisms of the three-phase vacuum circuit breaking poles are respectively connected with the synchronizing shaft. The miniaturized large-current handcart-type vacuum circuit breaker has the advantages of small size, light weight, long service life, maintenance-free, high flexibility and convenience in use.

The invention discloses a burst transmission method for an urgent service in a wireless body area network. A communication link tree network is used for distributing time slots in a sequence from bottom layer nodes to top layer nodes according to a network structure. The time slots are formed by an access time frame t0 and an access time frame t1 in the process of processing the urgent service and a time frame t2 in the process of transmitting the service. When the urgent service exists in a node, a time slot expropriating request begins to be broadcast in a next time slot. The t0 time frame of the current time slot is monitored, if the time expropriating request is monitored, priority is judged on the node where the urgent service occurs, the urgent service with high priority is transmitted in the t2 time frame of the current time slot, whether the urgent service is transmitted to a root node or not is judged, if not, the time slot expropriating request continues to be sent in the next time slot, and the steps are repeated until the urgent service is transmitted to the root node in a relay mode. According to the burst transmission method for the urgent service in the wireless body area network, large handling capacity of an ordinary service is guaranteed, and the urgent service is fast and reliably transmitted to the root node with little cost.
