Ethyl additive means one lubricant for all off-highway needs

Ethyl additive means one lubricant for all off-highway needs Traditionally off-highway equipment lubrication has been carried out by a series of specialist oils, each performing a specific function. This can lead to costly machinery damage due to accidental misuse. For example, if gear oil is poured into an engine, rapid failure will result; or if hydraulic oil is fed into a gear box it will lead to seizure because it does not have sufficient extreme pressure or antiwear properties. A multi-functional oil which could be used for all types of vehicles and equipment as well as all their various parts would solve misapplication problems and would also provide benefits by reducing capital tied up in stocks, cutting inventory control costs and by simplifying maintenance procedures. A newly developed additive package from Ethyl Petroleum Additives makes such a lubricant possible. In addition to offering the user of off-highway and construction equipment time and money savings and a means of avoiding misapplication problems, it provides, they say, strong engine performance, base stock compatibility, gear, transmission and compressor performance, and high tolerance to water, whilst maintaining good filterability. The performance of this additive package demands the use of high quality base oils and viscosity modifiers

to ensure the finished oil has the rheological properties to cope with all climatic conditions. This is particularly important for hydraulics where good performance over a range of ambient temperatures is often an area for concern.

Plastics for fast-food dispensers The choice of plastics for the major components of an electronic doughnut and pastry filler has been justified by the way in which heavily-used machines are showing no signs of the corrosion and wear that normally affect metal. Knowing that highly abrasive sugar granules would scratch painted or treated metal surfaces and that steel would be corroded by hot jam, the company decided to use hoppers, console and tray mouldings supplied by the specialist industrial plastics thermoforming division of Williams Cox Ltd.

The company is producing the parts in 4.75 mm thick self-coloured high impact ABS plastic sheet. Some of the electronic fillers have been in daffy use in supermarkets for nearly 12 months, dispensing up to 10,000 fillings on a Saturday. Hoppers are interchangeable

Future trends in surface finishing technology

The keynote address will be given by George J Rudzki, President of the US based International Forecasting Institute. In subsequent sessions, authors from Europe, the United States and the U.K. will present papers on engineering and tribological coatings, electronics applications of surface technology, aluminium finishing, corrosion protection, design and quality. Of particular interest to engineers and designers concerned with product finishing will be the sessions on corrosion resistant coatings, techniques for the improvement of wear resistance and other surface properties, design for cost effective finishing, quality and reliability - Quality Assurance to British.Standard 5750.
