IPC: H01F41/02
Abstract: 1,051,372. Assembling laminated cores. MAGNETIC & ELECTRICAL ALLOYS Ltd. Sept. 2, 1965 [Sept. 2, 1964; Feb. 19, 1965], Nos. 35848/64 and 7266/65. Heading B3A. In a method of making a laminated core for a coil single laminations are taken alternately from each end of a batch, aligned relative to the axis of a coil and fed alternately into each side of the coil. In the apparatus shown a batch of E- shaped laminations 21, Fig. 4 (not shown), is laid on rails 19, 20 and single laminations removed from the ends by suction pipes 32, 33. The pipes 32, 33 are carried on a carriage 26 which is mounted for reciprocation on bearings 28. When the carriage moves leftwards a single lamination is removed from the batch by the suction pipe 32 and carried towards doffing bars 40, 41 which displace it downwards on to a platform 43, 44 where it lies horizontally with one limb aligned with a coil former 5. When the carriage is moved rightwards the lamination is pushed between a guide spring 53 and a pivoted, spring-loaded stop 52 by stops 57, 58 and one limb enters the coil former 5. When the carriage again moves leftwards the lamination is held in the coil former by the stop 52 and when it is free of the platforms 43, 44 the spring 53 urges the lamination to the bottom of the coil former 5 as another lamination lying on platforms 46, 47 is fed from the right by means of suction pipe 33, doffing bars 59, 60 and stops 47, 48 by a process similar to that previously described. The coil former 5 is held between cross pieces 14, 15 and a support 4 which is carried on a platform 6. The coil former is inserted and removed by lowering the platform 6 by means of a ratchet and ratchet wheel 10, 11, Fig. 3 (not shown), and unlocking a latch 13, Fig. 3, which retains the support 4 to the platform 6. The laminations may be stacked inside the coil former in a variety of ways including the stacking of symmetrical E-shaped laminations with overlapping joints or the stacking of unsymmetrical laminations 21, Fig. 4, to form staggered butt joints between the laminations inserted from opposite sides of the former. In this last case the laminations are stacked on the rails 19, 20 with alternate laminations reversed. As an alternative to the suction pipes 32, 33 magnets may be used for removing the laminations from the stack on the rails 19, 20.

Abstract: 1,054,924. Electric motors. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 18, 1963 [Oct. 24, 1962; Sept. 17, 1963], Nos. 40325/62 and 36549/63. Heading H2A. In a synchronous induction motor having a squirrel cage rotor which synchronizes by virtue of having axes of high reluctance, the rotor has a plurality of circumferential magnetic segments 6 separated by comparatively narrow air-gaps 4. These air-gaps may be 1/10-1 times the circumferential extent of the segments, and are preferably about 1/6 to minimize the quadrature flux without reducing the main axis flux. A further improvement may be made by removing the inner corners 7 of the segments. The segments may be joined across the air-gaps 4 by thin bridges of metal stamping (Fig. 4, not shown) to provide mechanical strength. Improved performance may be achieved by cutting shallow channels or flats in the centres of the segments. It is also described (Fig. 5, not shown) how the segments may be located between salient poles and these may include radial slots. The segments may be secured by the cast squirrel cage. The rotor may be axially divided to permit the insertion of a conventional squirrel-cage section (Fig. 6, not shown)

Abstract: 1,226,637. Key mechanism. SPERRY RAND CORP. 19 Dec., 1968 [20 Dec., 1967], No. 60395/68. Heading G4B. A pivotally mounted operating bar of a tenkey calculator, similar to that described in Specification 1,172,702, selectively moves an articulated lever 60 having an inclined ramp 60a so that the ramp laterally shifts a member 80 to align a cam follower 61 with a selected track of a multiple track cam (12), Fig. 1 (not shown). As described the operating bar (26) has a stem which engages a slot 101 in a pivotally mounted lever 102 biased by a spring 103 into a neutral position and articulated at 107 to the lever 60. For total and sub-total taking an abutment 20a on the pin carriage which is cleared to its extreme right position forces the lever 60 against a stop 60b. Depression of the lower portion of the bar (26) (sub-total) drives the lever 60 forward so that the ramp 60a displaces the member 80 to the right aligning the follower 61 with the extreme right hand track of the cam (12). Depression of the upper portion of the bar (26) withdraws the ramp and allows the follower 61 to move one track to the left on the cam (12). For addition and subtraction the pin carriage is displaced to the left and the lever 60 is moved away from the stop 60b by the action of a spring 81. Withdrawal of the ramp 60a by depression of the upper portion of the key (26) (addition) causes the follower 61 to shift to the extreme left hand track of the cam (12), while depression of the lower (sub-traction) portion of the bar (26) drives the ramp 60a forwards the shift the follower 61 one space to the right.

Abstract: 1,233,536. Fluidic servosystems. WESTLAND AIRCRAFT Ltd. May 21, 1968 [May 24, 1967], No. 24186/67. Heading G3P. A system for sensing variations above a predetermined value in a known parameter e.g. speed of a compressor or turbine shaft 1, the temperature or pressure of the working fluid thereof and for restoring the parameter to below said value comprises means e. g. a tuned vibrating beam 13 responsive to said variations, a fluid logic element 15 responsive to said tuned vibrations for applying an output signal through a control line 28 to a further fluid logic element 16 thereby directing a signal therefrom through an output line 39 to cutout means 41 for restoring said parameter to below the predetermined value. The shaft 1 carries a wobble plate adjacent sensing probes 2, 3 connected to a compressed air line 4 and transmits pulses to probes 11, 12 adjacent beam 13. At normal shaft speeds the delivery of the power nozzle 19 of element 15 which is supplied from a compressed air line 17 is directed through a restricted vent line 21 by means of biasing pressure exerted through a branch 26 of line 17 and a control nozzle 34. The power nozzle 20 and control nozzle 36 of element 16 are supplied from a compressed air line 18 and a branch line 33 including a momentarily opened solenoid valve 32; the output of 16 being directed through a vent line 29. When beam 13 is excited due to increased shaft speed a pad valve 14 in line 26 is opened and the output of element 15 is switched from line 21 to line 28 resulting in the output of 16 being switched from 29 to 39 and to the cut-out 41. Reduction of speed of shaft 1 results in gradual reduction of amplitude of vibration of 13 and closing of valve 14 and eventual switching of the output of 15 to vent line 21, but the output of 16 remains in line 39 until the solenoid valve 32 is momentarily re-opened.
