IPC: H02K49/04
Filed: 1958-10-03
Abstract: 877,437. Eddy current couplings and brakes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 2, 1959 [Oct. 3, 1958], No. 31685/58. Class 35. In an eddy current device, shown in Fig. 1 as a brake comprising relatively rotatable, relatively axially movable primary and secondary members 1, 5 disposed one within the other, the primary member 1 carries a permanent magnet structure 6 defining a ring of alternate N and S poles 8 and the secondary member 5 carries axially off-set main and secondary elements 3, 4 of which the former when opposite the magnet ring affords a return path for the magnet flux and includes rotationally fast with the secondary member 5 a cylindrical electrically conductive part which provides a circulating path for torque transmitting induced eddy currents, whilst the secondary element 4 when axially moved to a position opposite the magnet ring instead of the main element 3 also affords a flux return path but is so constituted as not to transmit torque between the members. This constitution comprises laminating the element 4 and mounting it on bearings 17 so as to be freely rotatable, The conductive part may be either the magnetic body 12 itself affording the flux return path or a copper coating 15 thereon, and the coating may have a graded thickness in the axial direction to produce optimum braking characteristics. Guides 11 permit the axial movement and prevent rotation of the member 1. The axial movement may be controlled by a face cam 18 and linkage 19 driven through reduction gearing 20 by the shaft 5, and may control the rate of decent of nuclear reactor control rods reference being directed to Specification 832,694. In the Fig. 3 embodiment, the solid or laminated body 21 affording the flux return path of the main secondary element is rotatable on bearings 22 to reduce inertia. In modifications, the device may form a coupling in which both members are rotatable, the rotor member 3, 4, 5 may be axially movable instead of the stator 1, and the stator 1 may carry the secondary elements 3, 4 whilst the shaft 5 carries the magnets 6.

Title: Improvements in or relating to a regulating system for a dynamoelectric machine
IPC: H02J7/26
Filed: 1956-10-18
Abstract: 829,420. Magnetic amplifiers. LEECENEVILLE CO. Oct. 18, 1956 [Dec. 8, 1955], No. 31751/56. Class 40 (9). [Also in Group XXXV] In a system for regulating a dynamo-electric machine, the field is energized in accordance with a signal representative of machine loading through a " Ramey " resetting type magnetic amplifier having an inverse transfer characteristic whereby the load current output of the amplifier varies inversely with the control signal, a "Ramey" resetting type magnetic amplifier being one using a core having a substantially rectangular hysteresis loop, and having control and load windings which are alternately energized, wherein the load winding itself effects saturation and the output is determined during the preceding half-cycle by the remanence point to which the core is reset by the input to the control winding. The inverted characteristic is obtained by controlling the amplifier by the additive combination of a reference signal and the control signal and the operation is described in detail with reference to Figs. 3-6 (not shown). The D.C. voltage applied to a load 13, Fig. 7, from an alternator 11 through a rectifier 15 is maintained constant by controlling the alternator field 12 through a full-wave arrangement of magnetic amplifiers of the type described above 23a. Current compensation is provided by a current transformer 27 in one of the phases providing a potential across a resistor 29 in the amplifier input circuit in opposition to the voltage signal, and the reference voltage obtained from winding 60 of transformer 61 (the dots indicating the instantaneous positive potential), is applied with the compensated signal across lines 24a, 25a to the control windings 52, 53. Load windings are fed from winding 70 of the transformer 61 and the resulting output across resistor 76 is applied to a magnetic power amplifier 23b and also of the resetting type in which windings 81, 82 each serve alternately as control and load windings. Cross-connected feedback winding 65, 67, 83, 84 are provided in each of the amplifiers to compensate for the low back-resistance of the rectifiers. A load relay 102 prevents the connection of the load before the alternator has run up to speed and its contacts 105, 106 are closed during this period. A further current transformer 31 is arranged to take over the control when the current exceeds a predetermined limit and when a further alternator 108 is feeding a common load with the alternator 11 desired load sharing is maintained by the opposed outputs from current transformers 110, 114. Resistors 63 and 100 improve the regulation and prevent oscillation respectively, and a temperature-sensitive resistor 38 provides temperature compensation.

Title: Improvements in or relating to protecting electric circuits and alternating current machines, from material disturbance of equilibrium of phase and excessive strength of current
IPC: H02H3/34
Filed: 1923-12-22
Abstract: 234,153. Nicaise, E. Dec. 22, 1923. Drawings to Specification. Cut-out arrangements.-Relates to the protection of polyphase circuits by means of current transformers in each phase the effects of which are compounded by connecting them separately to windings on a single transformer or to separate transformers the secondaries of which are connected together in series through a protective relay. In order to render the protection effective in the case of balanced overloads on all the phases as well as in the case of unbalanced overload due to faulty conditions, one of the windings has a different number of ampere-turns from the other two. The number of windings supplied from each phase, may be different one from another. To deal with faulty conditions when the circuit is open but under tension, resistances or capacities may be switched in between the phases to supply current to energize the protective current transformers and isolate the system when the voltage fails.

Title: Tape loop control
IPC: H02P5/48
Filed: 1962-08-23
Abstract: 967, 865. Automatic tension control. SPERRY RAND CORPORATION. Aug. 23, 1962 [Nov. 9, 1961], No. 32359/62. Heading G3R. A tape transport system comprises reels 10, 12, driven by reversible motors 32, 34 and magnetic tape 14 for storing digital information associated with head 22. The tape passes into vacuum loop boxes 18, 28, to form loops 19, 29. Capstan 24 is rotated by reversible motor 48 under the control of clutch 52 and brake 54, forward and reverse signals for the capstan being applied to lines 66, 68. When a read-write signal at terminal 86 is of a first sense the clutch is engaged and the brake released, the capstan then being rotated in a direction corresponding to the signal at line 66 or line 68. When the signal at terminal 86 changes to a second sense, the clutch is disengaged and the brake is applied. A trigger circuit 100 responds to signals from lines 66, 68, to release reel brakes 96, 98, and start reel motors 32, 34, thereby establishing the desired loop lengths in boxes 18, 28, in preparation for operation of capstan 24. During the reading or writing operation, a signal from terminal 86 maintains the operation of the reel motors. The vacuum loop box 18 has a plurality of apertures 112-121 connected to individual vacuumoperated switches, the vacuum loop box 28 being similarly constructed. With the loops 19, 29, oriented as shown, the system is conditioned for transport of the tape in the forward direction from left to right, the opposite balance points of the tape being established for movement in the opposite direction. The balance points established for the tape loops are shifted in dependence upon the presence or absence of a signal at terminal 86 as well as in dependence upon the signals at lines 66, 68. The voltage across resistor 252 is a direct function of the length of loop 19, the effective resistance of resistors 222-232, as selectively established by the vacuum switches, being increased as the tape increases in length. Only those switches which are below the tape loop have their contacts closed. There is similarly established across resistor 259 a potential which is a direct function of the length of loop 29. Rate control is provided by resistor 253 and capacitor 255. A servo amplifier 320 responds to a deviation from a predetermined relationship between the input from line 330, representing the desired loop length, and the input from terminal 256, representing the actual loop length, and provides a control signal to reel motor 32 to correct this deviation. The value of the reference signal on line 330 is determined by the desired balance position of the loop. Smooth control of the loops from one balance point to another is afforded by an integrating circuit comprising resistors 322, 324, as well as capacitors 326, 328. Specification 920,788 is referred to..

Title: Improvements in or relating to means for operating the distributing slide valve of pressure air operated hammers
IPC: B25D9/16
Filed: 1929-10-24
Abstract: 338,696. Frankfurter Maschinenbau-Akt.-Ges. vorm. Pokorny & Wittekind, and K³hn, W. Oct. 24,1928, [Convention date]. Percussive hand tools.-In a fluid-pressure hammer, a sleeve valve is arranged at the end of the cylinder coaxially therewith, and is moved in one direction by the compression, and in the other direction by fluid pressure supplied from the cylinder to an annular area on a shoulder on the valve. The auxiliary passage is provided with a non-return flap valve. The main valve s is locked in both control positions. When the piston d descends and uncovers the port g fluidpressure passes from the cylinder to the annular area i and raises the valve against the excess fluid-pressure on its upper end. Port g is closed by a flap valve c which is mounted in a bore k closed by a screw cap and prevents the exhaust of the valve chamber when the main exhaust is opened. After the valve has been reversed, air passes by passage f to the bottom of the cylinder and forces the piston upwards. During the upward stroke, a port h is uncovered and the pressure retains the valve s in its raised position since the area i is greater than the area q, and both areas are subject to the pressure in passage f. When the piston enters the valve, the compression forces the valve downwards, which closes passage m and opens passage n to effect the down piston stroke. During the down stroke the air in front of. area i exhausts through port h and passage f. In a modification, the valve c is arranged in a separate casing with a T-shaped slot.
