Title: Improvements in electrically controlled governing mechanisms for elastic fluid turbines
IPC: H02P23/00
Filed: 1960-05-13
Abstract: 899,914. Elastic-fluid turbines. GENERAL ELECTRIC CO. May 13, 1960 [May 15, 1959], No. 16965/60. Class 110 (3). [Also in Group XXXV] A multi-stage turbine 10 having an output shaft 24, an inlet valve 18, an extraction valve 20 between stages, and an extraction conduit 22 connected to an intermediate stage, is associated with a speed governor 58 driven by the shaft 24 and coupled to transducer 62 providing an electrical signal to control-network 400. The pressure in conduit 22 is communicated to strain gauge 68 and an electrical signal therefrom is also supplied to the network, 400 which controls servomechanisms 76, 78. These mechanisms regulate the valves 18 and 20 respectively. When the speed of the shaft 24 increases, the signal from the transducer 62, which is powered by a high-frequency carrier from source 800, also increases. The signal is amplified and demodulated and a portion of it is fed to network 541. A portion of the signal is also fed over line 540 to govern the valve 20. A speed error signal is supplied from network 541 to a further network 546 which also receives a signal through line 550 related to the pressure in conduit 22. The resultant signal from the network 650 is attenuated and amplified, and, if the signal does not exceed a predetermined value, it is limited by diode clipper 657. The clipped signal is then passed through network 659 to power amplifier 742 controlling the servomechanism 76 for closing the valve 18. A feedback signal from the valve is applied to network 659. The speed error signal over line 540 adjusts the position of valve 20 to compensate for the new position of the inlet valve, thereby keeping the pressure in conduit 22 constant. If there is a sudden increase in the speed of the shaft 24, a circuit 690 eliminates the clipping function of the limiter 657 to effect movement of the valve 18 at an increased rate and protect the turbine against damage. At the same time, the valve 20 is closed to maintain the pressure in conduit 22. If the demand for fluid in the conduit 22 increases, decreasing the pressure therein, the amplitude of the modulated signal from the transducer 68 increases. A pressure error signal from network 517 is amplified and combined with a signal from the speed channel, the resultant signal being amplified and clipped so that the valve 20 is closed at normal speed. A signal from the pressure channel is fed to the speed channel to open the inlet valve 18. A feedback signal from the valve 20 is supplied to network 606. When the valve 20 is moved to its fully closed or fully opened positions, in response to demands for fluid in the conduit 22, the gain of the speed control channel is increased through operation of circuit 680 to increase the speed of valve 18.

Filed: 1972-04-13
Abstract: 1360532 Machining piston rings; work transferring E F SULLIVAN 13 April 1972 [3 Jan 1972] 17152/72 Headings B3B and B3T A machine tool for use in the machining of the internal and external surfaces of piston rings and similar ring type workpiece comprises a hollow spindle 36 rotatably mounted in a headstock driven by a belt and pulley 44, 40 respectively, a ring feed device G carried by a frame 20 mounted on the headstock and which successively displaces rings P from a stock S to a workstation W adjacent one end of the work spindle 36. A housing H mounted opposite the headstock carries a ring displacing and clamping unit which is concentric with the work spindle axis and is axially displaceable by fluid means 24 to displace a ring supplied by the feed device G through a conically tapered ring closure member C to grip the closed ring between a cup member 10 on the shaft 29 of the clamping unit and a cup member 12 secured to the work spindle, the cup member 10 being rotatable with the work spindle and the workpiece to facilitate its machining. The closure member C is displaceable axially of the spindle 36 out of the workstation W by fluid means 32 in the housing H to render the workstation clear for machining of the clamped ring. The external machining of the ring P is effected by cutting tools 109, 12 mounted on respective fluid actuated tool slides. The internal machining of the ring is effected by a cutting tool 58 mounted on a slide 54 secured to the end of a hollow non-rotating shaft 48 concentric with the work spindle, the tool and slide being movable transversely of the shaft 48 by rotation of a shaft 64 concentric with the shaft 48 which carries at its end an eccentric 62 engaging in a seat 61 in the tool slide 54, the rotation of the shaft 64 being controlled to control the depth of feed of the cutting tool. The tool and shaft 64 are also axially movable. The displacement of the external tool slides may be by screw and nut and not by the fluid means shown. Rings with various shapes of crosssection may be machined by the apparatus disclosed.

Title: An apparatus and a method for heating or cooling and falsetwisting of running threads or yarns
IPC: D02G1/02
Filed: 1959-05-20
Abstract: 901,922. Finishing yarns; thread guides. ONDERZOEKINGSINSTITUUT RESEARCH N.V. May 20, 1959 [May 24, 1958], No. 17192/59. Classes 120 (2) and 120 (3). In a method of producing yarn having a tendency to shrink and curl by passing a yarn continuously between a false-twisting device and a twist barrier in a zone between which the yarn is heated and/or cooled, the path of the yarn over a guide member between the device and barrier is reversed and the member is given a movement, or component thereof, in the circumferential direction of the yarn as it passes over the member and in the sense of the rotational movement of the yarn at the place of contact with the member due to the twisting action thereon; the guide member thereby provides a shortened yarn path without obstructing the run of the (false-) twist therealong. In the curling apparatus of Fig. 1, a multifilament yarn 1 supplied from a spool 2 passes through an eyelet 3 to conveying mechanism 4 comprising two driven steel rollers and a rubber-coated pressure roller, thence through twist barrier 5 and heating tube 6 ; the yarn is reversed by a guiding system 7, returns through tube 6, is false-twisted by a spindle 8, passes through eyelet 9 and is wound on a tube 12 on a ring twisting machine. The system 7, Fig. 3, comprises an endless steel wire 13 running on rollers 17 at a speed corresponding to the circumferential speed, in the tangential direction, of the surface of the yarn. In a modification, Fig. 4, (not shown), the wire 13 running on four rollers passes adjacent both ends of the tube 6 and the yarn is reversed around the wire twice. Another modification, Fig. 5, comprises a rod 14 and high-frequency vibrators 15 and 16 which vibrate the rod in mutually perpendicular directions ; a phase differential between the vibrators, the frequency and amplitude are so adjusted that rod 14 develops a circular vibrating condition the circumferential velocity of which corresponds with that of the wire 13 in relation to the yarn. As shown in Fig. 6, yarn 1 (leaving tube 6) passes around two free or driven rollers 20, 21, the angle of false-twist and the angle of inclination of both rollers to the direction of travel of the yarn being identical, e.g. all 45 degrees. In further embodiments (not shown) of system 7, the yarn passes (a) through a flexible tube which is bent through 180 degrees and rotating about its axis so that the circumferential speed of its internal surface is equal to the rotational speed of the surface of the yarn, or (b) over a small direction-reversing wheel rotating at a circumferential speed much greater than the linear speed of the yarn.

Abstract: 1443121 Photo-electrophoresis XEROX CORP 19 April 1974 [23 April 1973] 17244/74 Heading G2H A photo-conductive suspension, located between two electrodes forming a moving nip, is illuminated imagewise or with uniform light ahead of the nip, which remains dark, so that light-struck particles migrate into the nip. In the nip the particles are squeezed dry, and form a positive image on each electrode. Separation positives may be made by illuminating a multi-sensitive suspension repeatedly through filters, and may be combined by successive transfer to a copy member. Alternatively an electrode may be given an even coating of photoconductive particles by exposure to uniform light through a slit ahead of a moving nip and may be used later, with the addition of a carrier liquid if need be, in photo-electrophoretic imaging by exposure of a further electrode nip.
