Title: Improvements in or relating to textile drafting systems
Inventor: GREENWOOD ROBERT
IPC: D01H5/42
Filed: 1965-07-20
Abstract: 1,135,752. Drafting - appartus; measuring sliver. T.M.M. (RESEARCH) Ltd. 4 July, 1966 [20 July, 1965], No. 30820/65. Headings DID and D1F [Also in Division G3] To reduce variations from standard in the mass per unit length in drafted material, drafting apparatus comprises means for measuring the mass per unit length of material being fed to a main drafting system, and control means responsive to deviations so measured to vary the draft in a control drafting system which acts on the material before it reaches the measuring station. Slivers are fed from cans 13 by driven feed-rollers over a table 14 and travel in turn around guides 15, through a control drafting system 16, through a converging guide 19, measuring rollers 21, 22, below and above spreading- guides 23 respectively to be delivered by rollers 26 to a main drafting system. The measuring- rollers comprise a vertically-displaceable disc 21 cooperating with a fixed grooved roller 22 driven at constant speed. The displaceable roller is coupled to a transducer which generates a signal related in phase-angle to the direction in which the disc is displaced. The signal from the transducer is amplified at 28 and fed to a servo-motor 29 supplying a variable input at 31 to a speed-changer 32. This also receives a constant speed input at 33 from the delivery rollers 26 and the variable output from it is delivered at 38 to the front rollers 17 of the control system 16 of which the back rollers are driven at constant speed from the rollers 26. The draft produced at 16 is normally between 1 and 2; when sliver of reduced diameter appears at the measuring-station, the disc 22 falls so that the phase angle of the transducer signal is zero, and the front rollers 17 are speeded to reduce the draft at 16. When the disc rises, the phase angle changes through 180‹ to slow the rollers 17 correspondingly and to increase the draft. The device will also compensate for the absence of a sliver or the presence of an additional sliver during piecing. Instead of a servo-motor clutches may be employed as in Specification 941405 to vary the draft of the control drafting-system.

Title: Improvements in and relating to fluid pumps
Inventor: POLLAK FREDERICK
IPC: F04C2/16
Filed: 1960-09-08
Abstract: 911,655. Screw pumps. HAMWORTHY ENGINEERING Ltd. Aug. 14, 1961 [Sept. 7, 1960], No. 30997/60. Class 110 (2). A fluid pump embodies at least two intermeshing rotors, as shown, rotors 1, 2, 3 mounted within an inner casing 12. The rotor 2 is driven by a prime mover through a shaft 5 and the other rotors, normally driven by the rotor 2 and freely rotatable about their own axes, are also capable of being rotated about the axis of the rotor 2 by an auxiliary prime mover through a shaft 14 keyed to an end-plate 11a of the inner casing 12. The shaft 14 is located axially by a thrust plate 16 which coacts with a bearing surface on the end-plate 11a to rotate the inner casing 12 and hence the rotors 1, 3 to vary the pump output. The rotors 1, 3 are mounted in bearings 6 and the rotor 2 in bearings 8. The endplate 11a and the end-plate 11b of the inner casing 12 are respectively supported on roller bearings 13a and ball bearings 13 within an outer casing 4. The auxiliary prime mover may be an hydraulic motor supplied through a pressure valve with fluid from the pump outlet, so that when output pressure of the pump reaches a predetermined value the valve opens to supply the auxiliary prime mover to reduce the pump output.

Patent GB-383738-A (GB)
Title: Improvements in and relating to drawing mechanisms in textile machines
IPC: D01H5/44
Filed: 1931-11-10
Abstract: 383,738. Drawing arrangements. LITTY, P., 8, Groitzscher Strasse, Leipsic, Germany. Nov. 10, 1931, No. 31158. Convention date, Nov. 25, 1930. [Classes 120 (i), 120 (ii), and 120 (iii)]. A machine for determining the correct spacing of drawing rollers for any particular draught comprises means for altering the distance between the nipping points of two pairs of feed rollers so that the roving takes on a waviness, this waviness being caused to disappear by correctly adjusting the roller spacing. The machine also comprises means for altering the draught. For the displacement of the nipping point a knife-edge 2 is provided, which is mounted on a member 1 pivoted at 3 counterweighted at 5, and operated manually bv the handle 4. When the handle 4 is raised the knife-edge 2 engages the roving and so displaces the nipping point of the rollers bl, b2 towards that of the rollers a<1>, a<2>, whereupon a waviness is produced in the roving in a vertical plane, the waviness being observed in an inclined mirror 8 and by the passage of the roving over an illuminated translucent plate 44. By moving the rollers the waviness is caused to disappear, and the correct distance between the nipping points is then read off of the scale 7. The pairs of rollers are journalled in housings g .. k. The housing g is fixed, and the housings h, i, k are moved by means of conveyer spindles n capable of rotary and axial movement, and having three separate threaded parts n<1>, n2, n<3>, the threads of which are differently handed and of different pitch ; by operating the handles 18, 18<1> separately or together, any desired spacing of the rollers may be obtained, their positions being read from the scale 7. For enabling the draught to be varied, the rollers are driven through step wheel gears 24, 36. By means of the crank e, or a motor, the front roller a<1> is rotated, and through a gear train, the shaft 21 is also rotated. The shaft 21 is slotted, and slidably mounted thereon and rotatable therewith is a gear 22 to which is pivotally attached an arm carrying a gear 27, which engages the gear 22 and the step cone 24, and so transmits the drive to the latter. The gear 27 can be engaged with any portion of the step gear 24 by means of the handle 28, and is held in position by a weight 29. The roller b<1> is driven from the step cone 24 by a similar arrangement of gears 30, 26, operated by a handle 31, and a gear train. The back roller d' is driven through gears 33, 34, 35 from the shaft of the step gear 24, and the roller c<1> is driven from the roller d<1> by a similar step gear 36 operated by a handle 39. Each gear train for driving a roller includes a gear mounted on a pivoted lever similar to that incorporated in the step wheel mechanism, so that the spacing of the rollers may be altered whilst a positive drive is maintained. The handles 28, 31, 39 for altering the draught are each provided with a calibrated notched scale as at 41, so that the draught between any pair of rollers can be readily ascertained.

Title: Improvements relating to transformer circuits
IPC: H01F29/04
Filed: 1956-10-12
Abstract: 806,840. Transformer arrangements. SOC. GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES ALSTHOM. Oct. 12, 1956 [Oct. 12, 1955], No. 31226/56. Class 38 (4). The voltage supplied to a traction or other load by the secondary winding 6 of a main transformer 2 is varied by adding to or subtracting from it the voltage of secondary winding 44 of an auxiliary transformer 38, the primary windings 37, 41 of which are energized from variable tappings on the primary winding 3 of the main transformer, the ratio of the auxiliary transformer 38 being altered on passing between buck and boost. The primary winding 3 is connected across the main supply and has tappings connected to circularly spaced contacts 14-20. With them co-operate rotating contacts 29, 30 to form an on load tap changing switch connected to resistor 47 through switches 33, 34. With these closed, Fig. 1 then shows the circuit arranged for lowest output voltage, the voltage of winding 44 being at maximum opposition to that of winding 6. Windings 37, 41 of the auxiliary transformer are energized in series from main winding 3 at terminal 5 and contact 14 through contacts 23, 25 of change-over switch 24, and contacts 39, 40 of switch 36. To increase the output volts by one step switch 33 is opened contact 29 is moved to contact 15, switch 33 is closed, switch 34 is opened, contact 30 is moved to contact 15 and contact 34 is closed. During each change, resistor 47 first develops a voltage drop in series with contact 30 to reduce the auxiliary transformer voltage, and then limits current between the connected taps. When contacts 29, 30 have stepped round to contact 22, windings 37, 41 are short-circuited, the output volts being those of winding 6. Contact 23 is then moved to 26 and further rotation of contacts 29, 30 connect increasing amounts of primary winding 3 to the auxiliary transformer in opposite sense so that the auxiliary voltage assists the main voltage. Before this boosting takes place, contact 40 of switch 36 is moved to engage contacts 35, 49. Only part 41 of the auxiliary transformer primary winding is now in circuit, thus changing its ratio and the value of each voltage step, and part only of resistor 47 is used to reduce correspondingly the voltage drop introduced into the circuit during each step. The rotary arrangement of contacts 14-20 allows the voltage steps to progress in value if desired, as the order of selection is the same both for reducing buck and increasing boost. The change in ratio allows the progression to continue smoothly. In a modification the tapping contacts are arranged linearly, Fig. 2 (not shown), the voltage steps then being equal. Various modifications are described including the following: resistance 47 may be replaced by a variable saturable choke; the switches may be dry, or oil-immersed, and may be assembled with or separate from the tap changer; the auxiliary transformer may comprise two separate primary windings or may be replaced by two transformers; and several circuits may be combined for polyphase operation.
