Title: Improvements in or relating to electrically operated apparatus for controlling pressure or flow
IPC: G05D7/06
Filed: 1949-05-28
Abstract: 691,348. Automatic pressure or flow-control systems. TINSLEY (INDUSTRIAL INSTRU- 1\IE-NTS), Ltd., and STEGHART, F. L. June 2, 1950 [May 28, 1949], No. 14354/49. Class 38 (iv). [Also in Group XXXVIII] In an automatic pressure or flow control system an amplified current proportional to the pressure or flow produces a force acting in opposition to a resilient force on a pivoted jet-pipe controlling the pressures on opposite sides of a piston movement of which corrects deviations of pressure or flow from a predetermined value. In Fig. 1, when the roof pressure in a furnace 2 deviates from a predetermined value a diaphragm 4, responsive through a pipe 5 to the roof pressure, and temperaturecompensated through a pipe 6, moves a mumetal core 10 from a central position in which a winding 9, energizedfrom a mains transformer 17, induces equal voltages in windings 7 and 8 connected in opposition. As a result, an alternating voltage appears between lines 12, 13 corresponding in magnitude and phase. sense to the magnitude and sense of the pressure deviation. This voltage is applied through a transformer 14 to the grid circuits of pentode valves 15, 16, the output of which increases or decreases the energization of a moving coil 18 as necessary to move core 10 towards its central position. The amplifier output also operates an electrical indicator 21 and recorder 22 calibrated in terms of pressure. At the same time the energization of a moving coil 23 coupled to a pivoted jet pipe 26 and biased by a spring 40, is increased or decreased to move the jet in one or other direction from a central position so that oil from a pump 28, driven by a motor 29 and associated with a safety valve 30, increases the pressure in one of two pipes 31, 32 and decreases the pressure in the other to operate an oil servomotor 35 in the appropriate direction to correct furnace pressure by adjusting the position of a damper 1 of furnace stack 3. A servomotor 45 which forms a link between pipe 31 and servomotor 35 moves in the opposite direction to return the jet towards its central position by means of lever 38 and provide feed-back proportional to the integral of pressure deviation. A bleed valve 41, associated with servomotor 45 permits the return of that servomotor towards its central position under the action of a spring 42. By. pass pipes 43, 44 allow oil to flow from pipe 31 to servomotor 35 at the limits of operation of servomotor 45. The pressure to be maintained by the system is set by adjustment of spring 40. In a modification, Fig. 2 (not shown), rate of flow in a pipe is maintained constant, pipes corresponding to pipes 5 and 6 being associated with each side of an orifice plate and a servomotor corresponding to servomotor 35 adjusting a valve controlling flow, apparatus corresponding to servomotor 45 and lever 38 being omitted.

Title: Method and apparatus for air classifying particles of material
Inventor: LISOWSKI HENRY JOHN
IPC: B02C11/00
Filed: 1966-03-31
Abstract: 1,099,165. Air classifiers; impact pulverizers. STURTEVANT MILL CO. March 31, 1966, No. 14392/66. Headings B2A, B2H and B2P. Material to be classified is introduced by means of a screw conveyor (8) Fig. 2 (not shown) into the lower portion of a chamber C in a housing 2 where it is reduced into coarse and fine particles by rotary impactors 22-26 cooperating with stationary elements 16-20. The particles are entrained upwardly into a classifying zone G of the chamber by a spiralling air current produced by fans 30 and 36. Due to centrifugal force, the finer particles tend to accumulate towards the centre of the zone C and the coarse particles towards the periphery. As the particles travel upwards, they encounter rotary selector bars 32 which cooperate with a deflector wall portion 34 to reject coarse particles and regulate the size of the fine particles which pass out through the fan 36 to a discharge outlet (12), Fig. 1 (not shown). To prevent increasing quantities of rejected coarse particles from accumulating in the zone G, some of these are sucked through extractor tubes 62 which are transversely adjustable in tubular members 58, 61, Fig. 5, disposed around the housing 2 and connected to a circular manifold 40 into which the tubes 62 open. The manifold 40 is connected by means of a tubular member 44 Fig. 1 (not shown), to one end of a vertical pipe (46) through the other end of which air is blown by means of a compressor (48) via a control valve (50) so as to create suction in the manifold whereby the coarse particles are directed via a conduit (52) in communication with the tubular member (44) and the pipe (46) into a collector bag (54). Examples of material treated are corn meal, soy beans, minerals and pigments.
