BSP consists of. two types of threads - BSPT (British Standard Pipe Taper) and BSPP (British Standard Pipe. Parallel). BSPT threads have a slight taper similar to NPT. BSPP threads are straight (parallel) threads. and have the same thread angle, shape and threads per inch (pitch) as BSPT threads.
The movie the Exorcist was based on a book of the same name by William Peter Blatty. The book is based on the real-life attempt of a priest to exorcise a demon from a young boâ¦y (the boy was around the same age Reagan was in the movie).
The movie quickly became a phenomenon; when adjusted for inflation 'The Exorcist' is the ninth highest grossing film of all time in the United States. Yet few realize that author Peter Blatty based his novel on a real life case: the months-long exorcism by Jesuit priests of a 14-year-old Maryland boy in 1949.
