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).
Whatever, The Exorcist set new standards for gross-out horror films. It was praised by the Catholic church and though director William Friedkin touted the film as âa deeply spiritual experienceâ, he dumped author William Peter Blatty âs flaky âThousand Points of Lightâ ending, with souls twinkling in Heaven.
