Design of a feeder for miniature components: Investigation into the mode of operation and application of vibrating oblique blade
A brief review of work on the automatic feeding of silicon chips using standard electro-magnetic bowl feeders is given together with a review on a feeding method using a device consisting of a flat, chip-transporting surface and an obliquely angled, vibrating blade, positioned so as to plough the …

A study of the influence of ring gap size on the lubrication of piston rings in an internal combustion engine
The work presented in this thesis is largely concerned with developing a greater understanding of piston ring lubrication by measuring the thickness of hydrodynamic films developed between the piston ring and the cylinder wall of an internal combustion engine. It begins with a review on oil film …

Tribological Aspects of the Self-Loosening of Threaded Fasteners
Practically every engineering product with any degree of complexity uses threaded fasteners. Although threaded fasteners are generally considered a mature technology, significant problems exist with their use. This study has investigated a number of issues with the tightening and self-loosening of …

Strength in Flexibility; Research into Innovative Flexible Bearing Designs for Wave Convertor Permanent Magnet Generators
Originally this research was to investigate the use of hydrostatic bearings in large linear machines, such as linear generators, and determine their viability in a power generation context. It quickly became clear that it was possible to make hydro-static bearings viable, however the methods …

The fundamentals of two-phase flow in wet domestic central heating systems
An emerging trend in the building services industry is the installation of passive deaerators on the flow line of domestic wet central heating systems. To date, no data and theoretical models predicting the two-phase flow characteristics in domestic wet central heating systems are available in the …
