English

Subject field(s)
  • Closing Devices and Nozzles (Mechanical Components)
  • Engines (Motor Vehicles)
CONT

Valve rotation has an overall positive effect on valve life. Rotation provides improved temperature distribution in the valve head and a mild scraping action that cleans the valve interface of any crushed combustion deposits.

French

Domaine(s)
  • Obturateurs et buses (Composants mécaniques)
  • Moteur (Véhicules automobiles)
CONT

La rotation des soupapes assure une répartition uniforme de la température autour du siège et améliore la longévité en réduisant les distorsions locales et en évitant le passage des gaz dans le carter et la formation de craquelures sur la surface d'étanchéité. La rotation réduit en outre l'usure des autres composants en contact direct avec la soupape.

Record 2 2000-10-31

English

Subject field(s)
  • Metal Fasteners
  • Roofs (Building Elements)
CONT

... the nailing of wooden shingles and slates are entirely different. The heads of slating nails should just touch the slate and should not be driven "home" or draw the slate, but left with the heads just clearing the slate hangs on the nail. The opposite is true of wooden shingles and a man used to laying this material will invariably handle slate in the same way. As a consequence the slate, held too rigidly in place, is shattered around the nail hole, or the head of the nail crushed and eventually the slate may "ride" up over the nail and be blown off in a heavy wind... The temptation to use shingle nails instead of slating nails should be discouraged, for the slight saving in cost on the entire roof cannot approach the cost of repairs which may develop as a result of this practice.

OBS

Not to be confused with shingle nail.
