Craftsmen

The collection and use of lac by Indian aboriginal tribes probably predates recorded history. Ancient Greek and Roman writers were aware of lac. By the late fifteenth century, European craftsmen were attracted to the use of lac as a finish for cabinets and other furniture because of its gloss and luster. 

These incidents show the need for continual vigilance. We cannot assume that because we epiplpy- ualjified craftsmen and graduate engineers thi manner. 

A sample point on the suction line of two water pumps became choked, and a maintenance worker was asked to clear it. He was not told how to do so—craftsmen dislike people from other departments telling them how to do their Jobs—but the operators assumed he would use water under pressure or a rod. Instead he used compressed air at a gauge pressure of 115 psi (8 bar), and a pocket of air caused the pumps to lose suction (Figure 1-19). 

Impure, native platinum seems to have been used unwittingly by ancient Egyptian craftsmen in place of silver, and was certainly used to make small items of jewellery by the Indians of Ecuador before the Spanish conquest. The introduction of the metal to Europe is a complex and intriguing story. In 1736 A. de Ulloa, a Spanish astronomer and naval officer, observed an unworkable metal, platina (Spanish, little... 

Physical realizability is often the most difficult of the above three corollary questions to answer. In general, to answer this question it is necessary to know 1) whether the materials and components required by the engineering design are available and 2) whether the manufacturing (and/or fabrication) techniques and skilled craftsmen needed to fabricate the product are also available. These two assessments are difficult to make because they often involve the projection of future technological developments. Technological developments usually do not occur according to schedule. 

To enable the maximum input and experience of the craftsmen to be introduced into the system the pages of the handbook should not be encapsulated thereby enabling the craftsman to enter additional information and comments that could increase the performance of the plant and equipment as well as amended instmctions in the guidance notes. These amendments can then be issued to all staff in a similar trade. 

The engineer controlling the planned maintenance function within the department ensures that all work dockets are returned. Any comments entered on the work dockets are noted and, where further action is required, plans are prepared accordingly. Note A copy of the week tasks will suffice in maintaining a record of work dockets issued. If necessary, the technician/craftsman s initials can be entered on the week task form as a reminder to whom the work docket was issued.) Technicians/craftsmen should be advised of any matter that delays implementation of action required, as reported in the returned work docket, so that, if no corrective action has taken place on their next scheduled visit they understand why. 

The benefit to be gained by the engineer and techni-cian/craftsmen from the visual aid is that it provides them with a visual picture of the full year s program, covering all the recorded assets and their associated work tasks. The format of this visual aid depends on the number of assets within the system, and each visual aid may cover approximately 100 assets. 

Planned maintenance can reduce the demand for highly experienced craftsmen in that, if the instructions issued in work docket and advice/guidance notes are adequate, a less-skilled person should be able to perform the work task correctly. It follows that adequate training must be provided to ensure that, irrespective of the degree of the operative s skills and experience, the work task given will be carried out to the required standard. 

With the changing face of technology, it is imperative that service departments keep up to date with the latest practices. Training should not be restricted to any specific individual but should include engineers, technicians, craftsmen and, where appropriate, semi-skilled staff. 

The instructions given in these guidance notes do not cover every component part, but the technician/craftsmen is expected to carry out any necessary maintenance in accordance with their normal trade practice. 

Steel pipe is now entirely welded, except for joints which need to be taken apart for service, which will be flanged. It is essential that welding is carried out by competent craftsmen and is subject to stringent inspection [29, 30]. 

Stores of this size can be built, using standard size factory-made sandwich panels, cutting these to size, jointing and sealing on site. This form of construction is prone to fitting errors, with subsequent failure of the insulation, if not carried out by skilled and experienced craftsmen. The best system can be ruined if the base is uneven or by inexpert finishing of pipe entries, sealing, etc. 

With Kay gone, the house is quieter, but we realise how much his work as a painter has kept all us craftsmen up to the aesthetic mark as he used to say, in the dramatic manner of the young, he had no allegiance to anything but art. Gareth in particular misses him he...

The first iron used by man came from meteorites. It was very scarce, and was used mainly as an ornament. About the same time the alphabet was being discovered, clever craftsmen learned to extract, or smelt, iron from ores, using very hot furnaces. It was shaped into plows for tilling fields and into sailing ship parts. It was used to make wheels and to build buildings. 

He had taken the most interest in skilled workers, but that was normal since he was, in a way, a skilled worker himself. After the constmction was done (if it ever did get done), he would have craftsmen and laboratory assistants to help him operate it in the coming days of peace. One day a chemist-inmate had stopped him to talk about a new idea Ambros praised the idea and advised him to use it in a PhD. thesis "some day." The defense had not made the mistake of locating the chemist. Minskoff had found skilled workers, too, in Belgium, France, the Netherlands, and England. 

If it be intended to build a palace, the services of many different craftsmen must be employed, and a great variety of materials is required. Otherwise the palace would not be worthy the name. It is useless to use wood where stone is necessary. 

During the Middle Ages and even during the period of the early settlement of North America, silversmiths were considered important craftsmen in the community They created many items such as dinner flatware, vases, pouring vessels, and eating utensils, as well as jewelry required by well-to-do households. 

Environment and health-related problems DCM is toxic for the central nervous system, for the liver and the kidneys (MAK-value 350 mg/m ), and it is absorbable via skin. Furthermore DCM is a suspected carcinogen (classification care, cat 3). DCM is low volatile and the vapour is heavier than air, thus high concentrations may occur at ground level during application. Activated-carbon-filters are ineffective and normal glove materials are penetrated within a few minutes. The required breathing equipment is, however, hardly used by craftsmen, which results in several deaths every year.
