Abstract

This is a very complete review of the research work carried out on the very important subject of E.P. Lubricants. In this work Dr. Davey has himself taken a very prominent part. No one is therefore more capable of preparing this very valuable contribution than he.

Abstract

EXTREME PRESSURE OR EXTREME TEMPERATURE LUBRICANTS have been developed for two main fields—the lubrication of hypoid gears and as lubricants in metal working and it is of some interest to see how this development has occurred. Musgrave, in a most comprehensive paper on the Development and Lubrication of the Automotive Hypoid Gearf defined a hypoid as “a special form of spiral bevel gear in which the pinion axis is offset from the axis of the ring gear” and he pointed out that such gears had the advantages of quietness in operation, particularly at high speeds, greater tooth strength capacity, greater dependability and were more economic to produce as well as allowing lower body designs than spiral bevel or worm gears.

Abstract

IT has been shown that compounds containing reactive chlorine atoms, and in particular those possessing a Cl3C‐ group, show marked E.P. activity when blended in mineral oil. Bromine compounds have been shown to be superior in E.P. activity to analogous chlorine compounds. Tribrom‐thioacetals, analogous to the trichlor‐compounds already described, have been prepared and found to possess good E.P. activity when blended in mineral oil. Such compounds show E.P. properties of a similar order to those shown by the trichlor‐compounds, but are more expensive to prepare and are less stable than their chlorine analogues, undergoing decomposition if impure or on keeping for long periods or on excessive heating.

Abstract

Purpose – This chapter aims to show that attention to nicknaming as a form of language-making and sensemaking can provide a valuable avenue for exploring employees’ assessments of (mis)behavior. It highlights the connection between gender and language-making as central to the way workers assess and respond to (mis)behavior in different workplaces.

Methodology – The chapter uses an historical perspective and concepts drawn from sociology and organizational theory. It identifies nicknames and nicknaming practices from a wide range of documentary sources and oral sources.

Findings – In considering nicknaming in terms of sensemaking and language-making rather than simply as a form of humor, the chapter shows that derogatory names enable employees to address the tensions and conflicts arising from formal organizational practices, rules, and managerial imperatives and workplace relations. It emphasizes commonalities in nicknaming practices that extend beyond the micro-level of specific workplaces and in doing so illustrates that nicknaming is not simply a manifestation of humor but as importantly of inter-subjective processes through which workers construct group identities to enforce co-produced informal rules of behavior.

Social implications – The chapter illustrates the importance of workplace nicknaming and its implications for the way employees try to influence the behavior of others by condoning and/or shaming those who conform to or defy informal rules.

Originality – The chapter's originality lies in its focus on employees’ own assessments of misbehavior and on commonalities in nicknaming practices in different times and in different places.

Abstract

In this chapter, I review recent evidence on the developmental origins of health inequality. I discuss the origins of the education-health gradient, the long-term costs caused by early life adversity, and how early life experiences affect the biology of the body. Additionally, I provide complementary evidence on enrichment interventions which can at least partially compensate for these gaps. I highlight emerging lines of scientific inquiry which are likely to have a significant impact on the field. I argue that, while the evidence that early life conditions have long-term effects is now uncontroversial, the literature needs to be expanded both in a theoretical and empirical direction. On the one hand, a model linking early life origins to ageing needs to be developed; on the other hand, a better understanding of the mechanisms – both biological and socioeconomic – is required, in order to design more effective interventions.

Abstract

SCIENTIFIC lubrication is concerned with the effective reduction of friction and the efficient running of machinery and since this subject affects everyone to a greater or lesser extent it is highly desirable that some knowledge of the principles and practice of lubrication should be available to all. Since machinery is likely to play an even greater part in our lives in the future the need for knowledge of scientific lubrication is urgent and, with this in mind, a survey of education in relation to lubrication should prove valuable in assessing the present and future needs, and in finding the best ways of satisfying them. In such a survey the following five groups of people are involved :—

Abstract

IN a previous article (Ref. 1, 1966), Chichester‐Miles of H.S.A. discussed some of the advantages and opportunities offered by the use of V.T.O.L. aircraft in short haul air transport. In a more recent article (Ref. 2, 1969), Boorer and Davey of B.A.C. reviewed the characteristics and some of the operational problems of V/S.T.O.L. aircraft, and argued in favour of initial civil S.T.O.L. aircraft leading to V.T.O.L. developments as an effective part of the overall ground and air transport system of the 1970s, on the basis of a foreseeable market demand for such aircraft at ranges between 50 and 300 miles. Quoting from their conclusions: ‘S.T.O.L. commercial operations appear therefore to be just around the corner. V.T.O.L. commercial operations may be a decade or so away but, as and when a S.T.O.L. inter‐city transport system develops, the improvement of S.T.O.L. performance toward V.T.O.L. may well become attractive and perhaps even necessary.’

Abstract

POLYMERS are mixtures of compounds of similar chemical composition and of high molecular weights. Naturally occurring products such as rubber, cellulose, proteins and shellac, extracted materials such as asphaltic bitumens, and synthetic products, produced by a polymerisation process, are all included under this heading.

Abstract

Action learning is intended to enable a group of professionals (a SET) to tackle work problems, develop solutions and reflect upon the success and failure of their actions. As part of the UK construction industry's drive to improve learning and performance, four SETs of small and medium‐sized enterprises (SMEs) were established. This paper evaluates the capacity of action learning to promote innovation and use of technologies within a CIOB‐funded SET located in Watford. Construction companies were unable to address real problems related to their day‐to‐day activities due to competition. Instead, they identified an industry‐wide issue – a lack of quality recruits – and marshalled resources to provide better careers advice and promote opportunities for builders. The role of action learning in empowering construction SMEs to contribute to industry change programmes is explored.

Abstract

Silver‐glass die attach materials represent a significant advance in silicon packaging technology and are expected to displace gold‐silicon eutectic bonding as the preferred method of die attachment for high reliability applications. In this paper the rle of the glass in the adhesion mechanism of silver‐glass to gold and chromium/gold backed die has been determined using thermal analysis and X‐ray diffraction in addition to scanning electron microscopy and electron probe microanalysis of the sintered film. An adhesion mechanism is proposed in which the glass of the silver‐glass system migrates to the die interface during the firing cycle and chemically bonds to the silicon which is present at the surface of the gold‐silicon eutectic. Adhesion between the die back and the silver of the die attach material is by means of a simple mechanical bond between ‘fingers’ of glass and the sintered silver matrix. Thermodynamic and kinetic considerations suggest that insufficient silicon dioxide may be formed using chromium/gold backed die for acceptable adhesion. Processing changes are proposed which resolve this adhesion problem.
