Title: Improvements in or relating to electric motor control systems
IPC: B21C47/00
Filed: 1949-11-16
Abstract: 665,965. Control of two motors. GENERAL ELECTRIC CO., Ltd., and DALE, S. H. Nov. 9, 1950. [Nov. 16, 1949] No. 29342/49. Class 38 (iii). [Also in Group XXXV] Constant tension is maintained in a strip winder e.g. for a rolling mill by controlling the supply to the reelmotor in accordance with the linear speed of the strip, acceleration of the strip, and the speed of the reel-motor, plus its armature current (i.e. reel - motor - power). Means are also provided for energizing the motor to. maintain a constant tension on the strip at standstill. General-motor control system A strip 10 after passing between rolls 11, 12 is wound onto a reel 14 driven by a motor 15 with a constant energized field 16 and its armature supplied from grid-controlled rectifiers 23, 24. The fixed out-of-phase grid-voltage-component is obtained from an R.C. bridge 33 ... 36 fed from a tranformer 31, and the superimposed D.C. control voltage is injected between the cathode busbar 25 and the centertap of the transformer 31. This control voltage is supplied from a bridge circuit 70, 72, 73 having in one arm an amplifier valve 50 to which the control signals are supplied. Derivation of control signals A tacho-generator 41 having its field energized by the motor current gives an output voltage proportional to the speed and torque, i.e. the motor power. A second tacho-generator 48 driven from the rolls provides a linearspeeding of strip voltage. The acceleration component is derived from tacho-generator 48 through an R.C. network 82, 86 in the grid circuit of valve 84 which develops the required voltage across resistor 80 in its anode load circuit. The speed and power signals in opposition, plus the acceleration component are'fed in series to the grid off the control valve 50 with switch 52 in position 54. The standing tension is controlled by reactors 63, 64 having their saturating windings in series with the motor 15, whereby the output of bridge rectifier 60 varies with the armature current. This voltage, together with an adjustable bias from potentiometer 55 is applied to the control valve with switch 52 in position 53. This adjustable bias may also be used for bringing the machine up to speed, in which case the acceleration component may also be switched into the control valve circuit in switch position 53.

Filed: 1975-07-16
Abstract: 1519296 Fluidized - bed separators CENTRE STEPHANOIS DE RECHERCHES MECANIQUES HYDROMECANIQUE ET FROTTEMENT 16 July 1975 [25 July 1974] 29779/75 Heading B2H A fluidized-bed separator for sorting bodies of different densities, e.g. seeds, comprises a diffuser for fluidizing gas, consisting of a mattress of micro-balls contained in an enclosure 117 and supported by a porous bottom of the latter, the enclosure having a U-shaped cross-section and defining an annular, horizontal gutter which is rotatable about its vertical axis. A bed 118 of particles to be fluidized is disposed on top of the mattress. A paddle wheel 105 integral with a drive shaft 101 rotatable about a horizontal axis dips into the particles of the bed 118 for picking up therefrom a particular layer of bodies which in operation are fed to the fluidized bed and separate into different layers according to density. The paddle wheel is rotatable about a coaxial stationary cylinder 107 and is arranged to discharge the picked - up bodies into the cylinder through an opening 108 in its upper part. A screw conveyor 112 is mounted on the shaft 101 inside the cylinder 107 to carry away the bodies in a direction parallel to the axis of the paddle wheel. The paddle wheel is surrounded by a stationary cylinder 114 which has an opening 115 on one side of which the lower portion 114a is extended by a horizontal flat floor 116. The portion 114a and the floor 116 are constituted by spaced parallel blades. In operation, the horizontal floor 116 is immersed to a particular depthin the bed 118. The mutual spacings of the blades which form the floor 116 and the portion 114a are greater than the particles of the fluidized bed but smaller than the average size of the bodies floating in the bed at the particular depth in question so that these bodies, due to rotation of the enclosure 117 and hence of the bed 118, pass over the floor 116 and are picked up by combs 113 on the paddles of wheel and carried along the inner wall of the cylinder 114 until they fall into the inner cylinder 107 from which they are discharged by the conveyor 112 through an opening 110 onto a conveyor 111. A number of paddle wheels may be installed along the path of the rotatable enclosure with the floor 116 of the associated outer cylinder 114 immersed at different depths into the bed 118 to pick up bodies of different densities. Another paddle wheel arrangement and a modified fluidizing-air distributor are described.

Abstract: 159,601. Murray, J. Erskine-, and Robinson, J. Dec. 1, 1919. Sounds, comparing intensities of.-In comparing the intensities of sounds, particularlv in wireless direction-finding systems, the sounds are listened to alternately. The alternations are made so rapid that the sounds cannot be independently distinguished, but are heard as a pure note when they are of the same intensity, and as a series of harsh beats when the intensities are different. The alternations are produced by a high-speed rotary switch or like controlling-means. Fig. 1 shows the cir. cuit arrangement when applied to a wireless direction-finding installation having coils 7, 8 fixed at a definite angle such as a right-angle with respect to one another and rotatable so that the intensities of the signals received in the two coils vary. The rotary switch connects the telephone circuit 11 to the coils alternately.

Title: Improvements in or relating to the dehydration of liquids by azeotropic distillation
IPC: B01D3/36
Filed: 1952-11-26
Abstract: An aqueous solution of an organic compound which forms with water an azeotrope of minimum boiling-point is dehydrated by feeding the solution into an upper section of a fractionating column, introducing into the column, at a <PICT:0736984/III/1> level below the aqueous feed inlet, an entrainer consisting of a mixture of the organic compound and a liquid immiscible with water having a boiling-point below that of said azeotrope, maintaining the temperature at the head of the column at a degree such that a ternary vapour mixture comprising water, water-immiscible liquid and some of the organic compound to be dehydrated passes over as distillate, condensing the distillate, allowing the condensate to separate into an aqueous layer and a non-aqueous layer, returning the non-aqueous layer to the column as entrainer, and withdrawing anhydrous organic compound from the base of the column.  The process may be applied to the dehydration of methyl ethyl ketone (M.E.K.) using pentane or hexane as water-immiscible liquid. Aqueous M.E.K. containing 11.3 per cent water (i.e. the azeotrope) is fed (100 parts per hour) through line 3 to the top plate of column 2, which contains 23 plates and is heated by reboiler 4.  A mixture of pentane (50 per cent) and M.E.K. is passed from vessel 5 on to the thirteenth plate from the base of the column at 384 parts per hour.  The mixture is supplied, via line 7, decanter 8 and line 9, until the temperature at the head of the column reaches 55 DEG  C.; valve 6 is then closed.  The distillate from the column is condensed in condenser 11, and the condensate is passed to decanter 8 through line 12.  The upper pentane/M.E.K. layer is returned to the column through line 9, and the lower aqueous layer is withdrawn.  The temperature in the column just below the inlet of line 9 is maintained at about 64 DEG  C.  M.E.K. containing only 0.017 parts of water is withdrawn from the base of the column.  If the temperature at the head of the column rises above 56 DEG  C., a thermally-controlled element 13 opens valve 6 via connection 14, to allow an additional amount of pentane to enter the system from vessel 5; but if the head temperature falls below 54 DEG  C., some of the pentane is withdrawn from the system.  The aqueous layer withdrawn from decanter 8 contains 2.8 parts M.E.K.; this layer may be subjected to distillation to obtain the M.E.K./water azeotrope which is then recycled back to column 2.  The dehydration of tetrahydrofurane is referred to.
