METHOD OF LARGE-SIZE NOZZLE OF ROCKET LIQUID-PROPELLANT ENGINE (RLPE) CHAMBERFIELD: process engineering.;SUBSTANCE: outer and inner walls are assembled to form a chamber there between. Aforesaid chamber is sealed on the side of larger diametre with the help of circular welded seam. Temporary ...
he went home and then became the father of the Chinese nuke program, as well as their rocket programs. Thanks very much for nothing. The word idiotic did not really begin to describe the situation. Hell, they decided to confiscate his logarithmic tables because the guys looking at it had ...
I always give the Jeep a thorough walk around a few days before my long trips. This way if I find something that needs to be repaired, I have time before I head out. This time I noticed that the jeep service group failed to tighten the engine air filter cover, three screws were not...

The iconic Hershey’s Kisses have been around since 1907, produced with a nozzle that dropped the chocolate onto a conveyor belt. The candy was hand-wrapped until the introduction of automated wrapping in 1921, and the tissue paper tag was added as well. According to the company, the name ...
ASTM defines material extrusion, as “AM process in which material is selectively dispensed through a nozzle or orifice” [1]. Concerning polymers extrusion, the process can be done with thermoplastic-based materials, where the raw materials are either in the form of filament (FFF) or pellets ...
