Abstract

Purpose

This paper aims to present a case study of some current disorders affecting the stone‐panels of façade claddings, i.e. cracking, spalling close to anchorage systems and staining. The purpose of this study is to identify the origin of the mechanical and chemical disorders of the carbonate rock thin panels of the “Les Chênes 1” building of the University of Cergy‐Pontoise (France).

Design/methodology/approach

Mapping of the disorders, anchorage system investigation at spallings, chemical analyses of oil‐like stains were performed in order to characterize both disorders. Porosity and capillarity properties of the rock were measured and compared between samples collected outside and within a stain.

Findings

Mechanical disorders result from vandalism or poor implementation. Spallings are disorders very likely in evolution. Their occurrence may increase through time. Stains are made of silicone destabilization products.

Originality/value

A model is proposed for the formation of oil‐like stains. Water is required to destabilize silicone sealant and to drive the migration of the degradation products through the porous media and towards the surface of the plate exposed to rainfall.

Abstract

In the first article in this series, the author dealt with general classification and composition of oils, fats and waxes, and this went on to discuss the properties of drying and non‐drying vegetable oils. In this second part, the properties of animal and fish oils, fats and waxes will be considered.

Abstract

The poorly shod children of the proverbial cobbler have passed into legend and their state is presumed to illustrate a general tendency. This is possibly not merely that of neglect in applying a certain special skill or craft in the domestic sphere, but also alludes to the absence, in the particular domicile, of the type of product which the head of the household helps to manufacture during his working day.

Abstract

Statements by Lord Denning, M.R., vividly describing the impact of European Community Legislation are increasingly being used by lawyers and others to express their concern for its effect not only on our legal system but on other sectors of our society, changes which all must accept and to which they must adapt. A popular saying of the noble Lord is “The Treaty is like an incoming tide. It flows into the estuaries and up the rivers. It cannot be held back”. The impact has more recently become impressive in food law but probably less so than in commerce or industry, with scarcely any sector left unmolested. Most of the EEC Directives have been implemented by regulations made under the appropriate sections of the Food and Drugs Act, 1955 and the 1956 Act for Scotland, but regulations proposed for Materials and Articles in Contact with Food (reviewed elsewhere in this issue) will be implemented by use of Section 2 (2) of the European Communities Act, 1972, which because it applies to the whole of the United Kingdom, will not require separate regulations for England and Wales, Scotland and Northern Ireland. This is the first time that a food regulation has been made under this statute. S.2 (2) authorises any designated Minister or Department to make regulations as well as Her Majesty Orders in Council for implementing any Community obligation, enabling any right by virtue of the Treaties (of Rome) to be excercised. The authority extends to all forms of subordinate legislation—orders, rules, regulations or other instruments and cannot fail to be of considerable importance in all fields including food law.

Abstract

A LUBRICATING grease has been defined by the ASTM (American Society for Testing and Materials) as a solid to semifluid lubricant consisting of a thickening agent in a liquid lubricant. Other ingredients imparting special properties may be included.

Abstract

Environmentally adapted lubricants (EALs) have been a slowly growing segment of the lubricants business since the early 1970s. The evolution of environmental thinking has led to the change of focus, from biodegradability to renewability. In the future, the focus will be more on fuel economy and lower emissions. Technical development drivers include the availability of suitable base fluids and additives for lubricants formulation and the adaptation of technical standards, OEM specifications and eco‐labels. Important non‐technical development drivers include environmental management tools and eco auditing. Environmental policy, and procurement guidelines for cities and government organizations, clearly has a large impact. EALs have been repeatedly heralded as one of the few future growth segments of the lubricants business, hence the relatively large increase in R&D activity over the last decade. In sales terms, growth has been slow, limited by high cost and several other factors. For a good future development, both technical and political hurdles must be overcome.

Abstract

I felt myself the recipient of a great honour when asked to read a paper on this subject before your Society. One difficulty, however, at once confronted me, and that was that what your society might regard as an act of sophistication of food, I might believe to be only a perfectly legitimate manufacturing improvement. I had no wish to masquerade before you as a wolf in sheep's clothing, and therefore stated my position to your secretary. As a result of some correspondence, I think that he, as your representative, and I, both felt that granted such differences of opinion, they themselves constituted one of the strongest arguments in favour of the formation of a Court of Reference. There are, no doubt, many processes which are considered by their inventors and users as of advantage in the manufacture of food, whereas others regard them with the greatest distrust and aversion. In most cases I believe the members of both these classes to be high‐minded and honourable men. That being so, it is submitted that the best method of arriving at the real facts is the establishment of an impartial, broad‐minded, and capable Court of Reference, to which such matters should be submitted for examination and decision.
