A completely head-mounted full shift dust sampler for monitoring the lead-in-air concentration in a lead worker's actual breathing zone is described. A small filter head is positioned within 5 cm of the mouth and nose on an adjustable stalk. Air is drawn through a 1.25 cm diameter glass fibre filter at a rate of 0.51/min by a small rotary vane pump. Initial comparisons with a conventional lapel-mounted UKAEA head powered by a Casella pump show that the average lead-in air concentration in the true breathing zone can be significantly different from that around the lapel.

This paper aimed at finishing a two-stage oil-free high-vacuum system using a molecular pump as the main pump and a rotary vane pump as the backing pump. Before the pump’s inlet, there is a molecular sieve. With the assistance of the high and low vacuum measuring instruments and other accessories, the system can achieve limiting vacuum of 5×10-5Pa in the vacuum chamber whose volume is 0.085m3 and provide the high vacuum needed for vacuum coating equipments whose magnitude is 100mm.

An air supply system has been developed for the fuel cell of a mobile robot, named ROBHAZ, using a rotary vane pump with a muffler. Research is concentrated on the design of the system, not only decreases the sound pressure level to an affordable range but also provides appropriate air flow rate for the fuel cell with the maximum output of 500W. At the same time, it has small volume; outer diameter of 80mm and total length of less than 150mm; which enables its installation into the limited space of the robot system. The muffler was designed to have concentric pipes to form a dual muffler which corresponds to the intake and outlet of the pump, respectively. DC motor was assembled inside the inner muffler to save the space. Developed device is thought be a satisfactory air supply system for a fuel cell.
