Abstract: This invention discloses a pneumatic and cable-driven hybrid artificial muscle, comprising pneumatic actuator, pneumatic pressure regulating assembly, and cable drive assembly. The pneumatic pressure regulating assembly is connected to the pneumatic actuator to regulate air pressure in the pneumatic actuator for controlling the pneumatic actuator to extend or contract. The cable actuation assembly comprises a cable fixedly connected to the pneumatic actuator for controlling the pneumatic actuator to contract. In this invention, the artificial muscle employs a dual pneumatic and cable actuation mechanism. By leveraging the inherent stiffness of the pneumatic actuator, it can provide substantial actuation force for joint movement. Simultaneously, the cable actuation assembly can provide significant pulling force, effectively ensuring safety in human-machine interaction and offering sufficient bidirectional aiding force to individuals with disabilities who use the artificial muscle as an aiding actuation device.

Abstract: It is related to a process for purifying organic amines. The process comprises (a) providing an organic amine to a first vessel (5), the organic amine having a normal boiling point at one bar; (b) filling the first vessel (5) with inert gas; (c) heating the organic amine in the first vessel (5) to a sub-boiling temperature, wherein the sub-boiling temperature is at least 15° C. less than the normal boiling point; (d) cooling the vapor from the first vessel (5) in a second vessel (20) to provide a liquid; and (e) contacting the organic amine with a resin polymer matrix, wherein the resin polymer matrix is embedded with an amino compound selected from the group consisting of iminodiacetic acid, aminomethylphosphonic acid or a combination thereof.

Abstract: A method for purification of organic amines, comprising introducing a resin polymer matrix to a liquid containing at least an organic amine bonded to at least one metallic element, wherein the resin polymer matrix is embedded with an amino compound selected from the group consisting of iminodiacetic acid, aminomethylphosphonic acid or a combination thereof, and wherein the embedded resin polymer matrix binds the at least one metallic element, and the at least one metallic element is removed from the organic amine.
