Een tweede doel van het onderzoek was het verbeteren van de selectiviteit van de Diels-Alderreacrie. De vorming van ongewenste bijproducten dient zo veel mogelijk te worden voorkomen. [Pg.184]

Some of the above discussed precursor phenomena are also observed prior to diffusion driven phase transformations. A typical example are the conventional EM tweed images obtained in the tetragonal parent phase in high Tc superconductors and other ceramics. In a recent survey by Putnis St e of such observations it was concluded that in these cases the tweed contrast resulted from underlying microstructures fomied by symmetry changes driven by cation ordering. These symmetry changes yield a fine patchwork of twin related domains which coarsen when the transfomiation proceeds. However, in view of the diffusion driven character of the latter examples, these cases should be clearly separated from those in the field of the martensites. [Pg.329]

Only one instantaneous US Army electric detonator is described in Ref 23- It is M36, which is, accdg to Tweed (Ref 42b, p 653), the first electric detonator developed by the Army Ordnance Corps when it was required during WWII to equip airplanes with electri-... [Pg.847]

Accdg to Tweed (Addnl Ref Ad 97e, p 653), the M36 was not stable in storage because its MF chge easily deteriorated. On replacing MF/NS with LSt and gilding-metal Cup with A1 cup, a detonator with improved shelf life was obtd. This is known a s M36A1 Electric Detonator... [Pg.848]
