Brand new gear
Article Abstract:
The Gear Research Foundation organized several projects to identify areas of improvement needed by development work to enhance gear design. Majority of the research focused on improving the performance of worm gears in terms of noise emission and capacity. A back-to-back rig designed for testing single and multi-start worm gears was used in one of the projects designed to evaluate the potential for increasing load-carrying capacity. A comprehensive non-elastic contact analysis for cylindrical helicoid and 'Cavex-'type worm gears was developed through this project.

Plastic properties
Article Abstract:
Several developments in the field of plastic injection molding promise long-term benefits for the plastics industry. These include Moldflow's prototype Intelligent Process Control which allows for the consistent production of plastic parts. Mannesmann Demag's gas injection process results in up to 50% savings on material usage and improves the rigidity of molded plastics. A co-injection moulding process which enables two materials to be combined to form a sandwich structure or multi-colored components in the same mould is also available.

Article Abstract:
The UK pumps market is currently flourishing, with a surplus of 127 million pounds sterling in international trade in 1995. The overall market was worth almost 1 billion pounds sterling, making it the fourth-largest in the world. Pumps for oil, gas and petrol and for water and sewage both hold a 17% share of the market, with pumps for heating and ventilation and for other chemical sectors at 15% and 14% respectively. George Meller is a leading pump distributor, while manufacturers include Goulds Pumps and ITT Flygt.
