Abstract: A pneumatic action figure doll is disclosed with articulated limbs controlled by a hand operated pneumatic pump. The articulated limbs may comprise connected limb members and links configured to move in a plane. Operation of the handheld pump may cause the articulated limbs to extend and retract.

The doll may be articulated at the waist to provide movement of the torso when articulated arms extend and retract. The doll may be used alone or with other similarly configured dolls. The dolls may be placed opposite each other. Simultaneous extension and retraction of the doll arms in response to simultaneous operation of the handheld pumps may resemble fighting or boxing between the dolls.

One of the wing assembly and the actuator may comprise a contact element, and the other of the wing assembly and the actuator may comprise an elongate contact surface extending obliquely relative to the body axis. The contact element may move along the contact surface as the actuator moves between the rearward position and the forward position, thereby moving the wing between the retracted position and the extended position.

Abstract: A method and circuit arrangement for processing signals which are produced during disturbance-free examination of objects such as pipes or sheet metal, by reflecting ultrasonic waves at defective spots on the structure of the object. According to the method, a complete wave front is emitted on at least one section of the object which is to be examined by means of a plurality of independent transmitting elements, a wave reflected by the structure of the object is received by means of a plurality of receiving elements which are independent of each other, the signals received by the receiving elements are digitalized, and the digitalized signals are stored in a storage element according to amplitude and propagation time. In order to detect defective points on the structure of the object in a faster manner with improved signal/noise ratio, the defective points are detected by a phase-locked addition of the stored amplitude values of the propagation time.
