The purpose of this paper is to describe the development of a device to support rehabilitation of a patient's upper limb motion.

The device has five degrees of freedom by virtue of its link mechanism. It consists of Joints 1‐5. Apparatus for use in so‐called welfare applications, such as this device, must be safe, flexible, and lightweight. A pneumatic cylinder, arranged and integrated with the device, was used to operate it. The device has two rehabilitation modes corresponding to different rehabilitation contents. The first mode is the muscular recovery and movable region expansion mode (Mode A). The second mode is a practical function recovery mode (Mode B). A compliance control and a position control system are applied for those modes.

By arranging the pneumatic cylinder optimally, results show that the device has compact and wide operating range and compliance‐control performance for Mode A. Position‐control performance for Mode B was verified experimentally. Moreover, the paper evaluates the effectiveness of the device and its control system through electromyography, which confirms that the developed device can support a patient's rehabilitation training.

The device has a simple link mechanism and an attached pneumatic cylinder, thereby constituting a lightweight and compact mechanism. The device has two rehabilitation modes corresponding to different rehabilitation contents. Using the device, a patient can conduct muscular power recovery training, movable region expansion training, and upper limb practical function recovery training.

TAKE‐OFF performance requirements for transport category aircraft have been the subject of many technical discussions and conferences and having taken into account the opinions and suggestions of many interested parties, the FAA have decided to add new standards for approval of a reduced take‐off decision speed (V1) methodology. This would be for take‐off on wet and precipitation contaminated runways and it is considered that the proposal to lower V1 by allowing a reduced clearance over the end of the runway (screen height) would provide an increase in safety for rejected take‐offs on wet and contaminated runways.

MANY who realise the implications of White's book on The Organisation Man have probably closed it with the self‐satisfied reflection that ‘it can't happen here.’ That is the anodyne we generally swallow to protect us from disagreeable fears.

ELEVEN years ago a small group, of whom the writer was one, met in Oud Poelgeest Castle in Holland to consider forming a European body concerned with Work Study. They share a sense of pride that the Federation which emerged will celebrate its decennary next month. Sadly, of the four British members of that group only two survive to greet the event.

Details of Some Components Used for Subsidiary Services in Aircraft, Missiles and Space Vehicles. Pneumatic equipment supplied by Enots Ltd., the fluid engineers, controls the foam system on two fire fighting and rescue vehicles built recently by Merry‐weather & Sons Ltd., a member of the Tecalmit group of companies, for use at Speke. The pneumatic controls provide a simple, flexible command system for both delivery of the foam to the fire and for replenishing the vehicle's tank after use.

The paper aims to develop a robotic deburring method based on a new active pneumatic tool.

The paper presents a new active pneumatic tool, which is developed by integrating two industrial pneumatic deburring tools based on a double cutting action – initial cut followed by fine cut. A simple control method is developed, which coordinates the motion of the tools and the arm.

The study finds that the developed method can improve robotic deburring in terms of speed and accuracy.

The paper provides guidance for the design of a pneumatic deburring tool, its integration with an industrial robot, and robotic deburring control.

The new deburring tool prevents large contact force and bouncing from occurring during the contact transition. In addition, the developed deburring method demonstrates significant improvement in deburring speed and accuracy in comparison with other methods, which is translated into cost‐effective deburring.

The paper introduces an efficient robotic deburring method, which is developed based on a new active pneumatic tool, considers the interaction among the tool, the manipulator, and the workpiece, and couples the tool dynamics and a control design.
