摘要： A process for finely dividing melts according to the nozzle drawing process is described wherein the pressure gradient of the gas flowing into the inlet opening of the drawing nozzle is increased by the provision of obstacles to that flow of gas. The obstacles may be streams or jets of gas directed a traverse of the flow of gas.

摘要： In a process for the production of mineral wool fibers according to the jet blast process, comprising issuing at least one melt stream from at least one opening in the base of a melting crucible into a converging-diverging drawing nozzle, flowing a gaseous blasting medium into the nozzle substantially parallel to the melt stream so as to separate the melt stream into fibers, the blasting medium being drawn into the nozzle by suction due to a drop in pressure produced between the nozzle inlet and outlet, and passing the fibers and sent blasting gas into a diffuser connected downstream of the nozzle to reduce the gas rate of flow, the improvements which comprise effecting(a) a maximum drop pressure in the inlet of the drawing nozzle;(b) a minimum drop pressure in the diverging portion of the drawing nozzle over a maximum length without separation (transition) of the laminar boundary layer;(c) the subsequent pressure conversion initially with a shock at a constant cross-section of the drawing nozzle and subsequently in a subsonic diffuser.

摘要： An airstream impinging laterally on a thread can convey a running thread through an opening. This "placing" of threads in nozzles fails at elevated thread speeds. According to the invention, placing succeeds even at high thread speeds if a strong stream of propelling gas is divided in the nozzle into edge streams which are deflected outwards and a fine central stream which conveys the thread through the narrow opening.

摘要： To clean the ballast bed of a railroad track, a wheeled vehicle movable over the ballast bed contains a blower for generating a positive flow of air and a suction flow. A suction port is located on the vehicle spaced a given distance above the ballast bed. A pipe section outlet is located around the suction port. The positive flow of air is directed through the pipe section outlet so that it provides a circular air flow about the downward projection of the suction port. The circular air flow sweeps the surface of the ballast bed and any refuse swept up is drawn into the suction port by the suction flow generated by the blower.
