Abstract: A flow control system in a tobacco shredding machine or the like having a conveyor means for conveying raw material under compression up to a shredding port and a rotary drum cutter adapted to rotate in close proximity to the shredding port and shred the raw material forced out from the shredding port. A rotational torque of the rotary drum cutter is detected by a torque detecting means and the number of revolutions of the same cutter is detected by a number-of-revolutions detecting means, then on the basis of the detected rotational torque and number of revolutions the number of revolutions of the rotary drum cutter is controlled so as to give a target flow rate of raw material by a number-of-revolutions control means, and the conveyance speed of the conveyor means is controlled in synchronism with the rotary drum cutter by a speed control means. The flow rate of raw material can be maintained constant and the quality of shredded pieces is stable.

Abstract: A cylindrical inset forming a mixing chamber in a binary atomizing nozzle is mounted in a housing ahead of the nozzle discharge and is provided with radial boreholes. The liquid to be atomized, for instance water, and the atomizing gas, for instance air, are fed to the cylindrical inset, with the liquid arriving axially and the gas passing radially from an annular spacing surrounding the inset within the nozzle housing through the radial boreholes into the inset. The radial boreholes are located in several consecutive transverse plans when viewed in the direction of flow and are arrayed in mutually offset manner in the circumferential direction of the cylindrical inset.

Abstract: A sheet separating device for separating flexible disc-shaped sheet materials forming a stack. The sheet materials such as floppy discs have holes in the center thereof in register with each other to define a single hole in the stack. The sheet separating device of the invention includes an outer member having a chamber therewithin and an inner member provided in the chamber. The outer member has a contact surface in facing relation to the stack. The chamber within the outer member has an opening in the contact surface through which the inner member also faces the stack. The chamber is communicated with a vacuum source. The opening and the inner member have diameters larger than the holes in the discs. When the vacuum source operates, the inner edge of the floppy discs is drawn up by suction force from a gap defined by the outer member and inner member until the drawn edge of the floppy disc is blocked by the inner member. As a result, the disc is sucked to the device and separated from the stack.

Abstract: A process for optimizing the power consumption of electrostatic precipitators communicating with a boiler or the like includes a load indexed signal fed forward to a field power controller to approximate the required power levels. An optical transducer is provided in the boiler stack for monitoring the emissions therefrom and feeds back a signal to the controller proportional to the emission from the stack to trim the power level. The controller incrementally adjusts the field power by comparing the opacity generated signal to a continuously optimized limit in order to thereby optimize the power consumption by lowering and raising the field power in response to changes in the opacity. The measurement of power permits the process to be extended to include supervision of electrode cleaning, compensation for fields out of service and flow balancing.

A motor drives a nut over a driving sleeve. The other motor drives a threaded rod. By means of this design, a compact drive device is procured in the case of which all mechanical parts are located inside of the housing.

Abstract: This disclosure describes a fully automatic, compact and portable operational device for repetitious intravenous (parenteral) infusion of fluids such as blood or blood derivatives, plasma, platelets, serum, dextrose, Ringer's solution and saline contained in pliant bags, at flow rates that not only are normally encountered but also at massive flow rates that are rather often called for but for which no such automatic device has existed. This is accomplished in a manner that frees the operator completely from attending to the device except for changing over to additional fluid bags for successive administration of fluids in such pliant bags and without loss of time. The fast response of the device is due to the special design that insures fast response both in the pressure application and retraction parts of the cycle. The device produces automatically any desired constant pressure over a wide range of pressures onto the pliant bags, over the whole compression phase of the pressure cycle.
