Abstract: The invention relates to a safety device for pneumatic actuators, for preventing the actuator pinion from being violently ejected, comprising a circular seat, formed on the less diameter portion of the pinion, projecting from the actuator body, and housing a resilient ring element. The resilient ring element engages with the pinion restraining elements, provided on the less diameter portion of the pinion outside of the actuator body, for a time required for allowing the pressure inside the actuator body to be released, through a slot defined about the pinion larger diameter section because of the disengagement of the corresponding sealing gasket from the actuator body.

Abstract: A wiper blade comprising a body made of an elastomeric material; and a surface coating layer positioned on a surface of the body and comprising a fluorine-containing resin having hydroxyl groups in the molecules thereof and a hardening agent having reactivity with the hydroxyl groups and optionally a solid lubricant. The surface coating layer is formed only on both side surfaces of the body. Thus, the wiper blade has a high degree of flexibility and restoring property; a high degree of durability; and judders in a slight extent when it slides on a glass surface in contact therewith; a high wiping performance; and maintains its wiping performance for a long time.

Abstract: A book constructed of foam provided with manipulatives for use with enjoyment of the book is disclosed.
