system to develop new ones. In other cases, the regulatory agencies had taken the position that they themselves must develop the standards, and sometimes, notably in the case of the Environmental Protection Administration, the remits had been less than satisfactory, according to Mr Trowbridge. If this trend continued, he warned, there was real danger that American industry would find itself producing and purchasing to a host of mandatory standards that varied widely both in technical soundness and in their acceptability to the broad spectrum of producer, user, and public interests involved. A strong, consistent national standards policy that would set standards for standards was needed.
articulated Yale model 2000 tractor shovel built by the Construction Equipment Division of Eaton Ltd, and fitted with a structure which has satisfied the tests laid down in SAE Recommended Practice J 3 9 4 Minimum performance criteria for roll-over protective structures for rubber-tyred front-end loaders and rubber-tyred dozers. The structure consists essentially of a strong welded box frame of upright and longitudinal members with fishplate reinforcing at the corners. It is fully enclosed in a cab of conventional design. The entire unit is seated on and welded to four upright members integral with the main body section of the machine. All forces on the ROPS are therefore transferred direct to the chassis.
Roll-over protection on tractor shovel
The structure passed static laboratory tests that simulated a 360 ° roll-over down a 50 ° slope on hard clay at speeds from 0 - 1 6 km/h (0 to 10 mile/h). The deflections under load were never sufficient to endanger the driver.
Although not yet a mandatory requirement in the UK, the provision of roll-over protection on wheeled loaders and dozers is capturing an increasing amount of attention in user industries. Recent accidents, some of them serious, have highlighted the need for greater protection for operators. One of the first major users to take positive action is the Central Electricity Generating Board, which has decided that all new machines ordered shall be fitted with roll-over protective structures (or ROPS) that satisfy SAE recommendations. Now working in the coal stockyard at Hackney Generating Station is an
Human Factors in qualiw control The human being is part of many inspection systems because of his ability to detect a wide variety of defects with the aid of suitable instruments, and to make decisions on the acceptability of the product based on what he detects. But the human inspector is rarely perfect in either detection or in decision-making.
U N I V E R S I T Y OF SOUTHAMPTON Institute of Sound and Vibration Research Research Fellowship in Industrial Hearing Conservation Applications are invited for a Research Fellowship in the Hearing Conservation Unit. The post is initially for two years with a probable extension to a third year. Candidates should preferably have a Ph.D. with post-doctoral research experience in industrial audiology, sociology or attitude questionnaires. Knowledge of work-stud~ techniques in the industrial environment would also be an advantage. The successful applicant will carry out research into hearing conservation procedures in industry, using audiometric, attitude questionnaire and work study techniques. Salary within range £1929 - £3048. Initial salary will be dependent upon qualifications and experience. Applications giving a curriculum vitae and the names of two referees should be sent as soon as possible to the Deputy Secretary's Section, University of Southampton, Highfield, Southampton SO9 5NH, quoting reference No. AE135/R.

With quality costs running at almost 10% of manufacturing costs it is vitally important that the quality assurance system be designed with explicit knowledge of the human inspector. A symposium to be held from 29 - 31 May, 1974, at the State University of New York at Buffalo, USA, will bring together those in industry who are responsible for quality assurance and those Human Factors researchers, in industry and outside, whose techniques, data and theories are showing new ways of improving inspection performance. The aims of the symposium are: To improve inspection performance by the wider application of Human Factors data and methods To formulate and unify research policies in inspection so as to improve the utilization of research resources.
