On the Adhesion of Blanks to the Punch in Blanking and Piercing
CIRP Annals, 1981Blanks adhering to the punch after blanking during the backward stroke of the punch may cause problems as they fall uncontrolled into the tool and thus damage the cutting edges during the next stroke. There is a number of recommendations as how to break adhesion or how to avoid it, but there is little quantitative knowledge about the mechanism of ...

IGBT short-circuit protection is the key factor to improve the reliability of the power electronics system. The conventional short-circuit protection method based on $V_{CE}$ measurement detects the collector–emitter voltage of an IGBT to determine ...

Representations, 2000 THE STORY MOST OFTEN USED to signal the onset of Henry Moore's growing disloyalty to his art school training involves an unlikely and unprepossessing object. It is his copy of a high relief by a Renaissance master a relief of the Virgin's head.' Perhaps because the quality of the marble itself is less than impressive the stone today looks flat and ...

Straining behaviour in blanking process - fine blanking vs conventional blanking
Journal of Materials Processing Technology, 1995Abstract This paper is to present a comparative study of the straining behaviour of the material during fine blanking and conventional blanking. It can be demonstrated that if one metal hardens easier than the other, the resulting hardness distribution surrounding the blanked edge should reflect this phenomenon under different blanking actions.

Nursing Standard, 1988
His complaint is always that nurses - or at least their trade unions - are a greedy, ungrateful bunch who never say thank you. So Mr Clarke, thank you for your success in finding an extra £138.5 million to fund this year's pay award and the impact of clinical grading.

Eating is not merely a means of survival, it is tied to the mechanisms, with all the rules and underlying connotations, in establishing social relations: in other words, sociality shaped through shared meals. In this perspective, food presentation plays a fundamental role, acquiring in its appearance an aesthetic virtue. In today’s social imaginary, we

Laser blanking vs. die blanking
International Congress on Applications of Lasers & Electro-Optics, 2000At the dawn of this twenty-first century, the North American automotive industry is enjoying decade long prosperity and growth. Part of this success can be attributed to a sustained drive to develop and implement new technologies and methods for enhanced productivity and efficiency.

The Development of Burr-Free Blanking: Roll Blanking
1981Optimum conditions were studied to achieve clean, burr-free blanking using a newly developed method called roll blanking. This method consists of two steps; that is, in the first step the sheet metal is half-sheared, but not subjected to perfect separation of blank and scrap, and in the second step the material is passed through a roll gap adjusted to ...

Critical Inquiry, 1997
Leaving aside a question to which I'll return, that of the blank stare, it seems blankness first appeared as the ground for a signification that it facilitated but that antedated it. According to Meyer Schapiro the smooth white ground common to most pictorialisms was quite a late development.' Blankness, then, was a response to the pictographic rather ...
