Title: Electric motor overload protection
IPC: H02H7/08
Filed: 1976-06-03
Abstract: 1502067 Control of DC motors PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 June 1976 [6 June 1975] 22966/76 Heading H2J For use with a variable, cyclically switched power supply circuit which includes a rectifying bridge having at least two thyristors 32, 33, a thyristor firing circuit 41, and a high power dissipation resistor 28 connected between the bridge and A.C. mains supply terminals, a permanent-magnet electric motor overload protection circuit 20 comprises means for detecting small residual voltage pulses which appear across the motor terminals 34, 35 and which have a polarity which is opposite to that of the voltage supplied to the motor, said pulses occurring at twice the frequency of the mains supply and each commencing in one half cycle of the supply voltage and ceasing in the next half cycle, the duration of said pulses being longer when the motor is stalled than when it rotates, and means responsive to an output of said detection means, which is provided when the motor is stalled, to provide a control signal for application to the thyristor firing circuit so as to retard the firing of the thyristors until slightly before the end of each half cycle whereby the current in the motor 40 is maintained at a very small value in a stable manner. Figs. 2 and 4 show respectively the voltage appearing across the armature terminals of the motor in a stalled condition and in a rotating condition. In the stalled condition, the duration for which the voltage is slightly positive, i.e. between constants t 3 -t 4  and t 6 -t 7  is considerably longer than the duration for which the voltage is positive, i.e. between t 14 -t 15  and t 18 -t 19 , in the rotating condition. As shown in Fig. 5, the negative terminal 34 of the motor is connected to an information point 78 of the protection circuit 20 and the positive terminal 35 is connected to a line 76 which is used as a reference. The combination of transistors 80, 84 produce, at the collector of 84, a pulse signal in accordance with the voltage which appears at point 78. Point 78 and the collector of 84 are connected to an integrating capacitor 89 via resistors 90 and 87 respectively, and it is arranged that when the motor is running, the voltage at point 88 is negative, but that when the motor is stalled, the voltage at point 88 is positive. A positive voltage at point 88 causes a transistor 94 to conduct and thereby lower the voltage at a point 57 of the thyristor firing circuit to thereby retard firing of the thyristors 32, 33. A warning may be given by a L.E.D. 102.

[Class 39 (i).] The control grid 2, Fig. 2, and the anode 3 are each provided with a cooling fin 6 and one or each is supported from one side in cantilever fashion by several support rods 7 attached to a fin 6 parallel to the cathode 1. In a modification, Fig. 5, the anode 16 has no cooling fin and is totally enclosed in a screening grid 19 with a fin 6. In both forms, the grid 2 and the anode 3 may be of pressed gauze, or the grid may be of stamped sheet metal as described in Specification 345,949, with slots 4 extending nearly half-way or all round, the fin 6 being integral with the grid. The cathode 1 may be directly or indirectly heated. The rods 7 may be received in channels in the fins : to allow for thermal expansion, the fins are welded to the outer rods at one point only. The rods 7 are steadied at the end remote from the pinch by a glass bead or by a drilled lavite insulator or by a metal frame with lavite bushings, a screen preventing conducting deposits distilled from the electrodes. The anode is split to allow the fin on the grid 2 to pass outside for free radiation of heat. In Fig. 5, the anode 16 is supported by insulators 21 in end-plates 20 of the screen 19. In another screened-grid valve, a screening grid is inserted between the anode 3 and grid 2 of Fig. 2 and is supported by fins extending out of the split in the anode to support rods at each side of the fin on the control grid. In a pentode with the control grid 2, Fig. 3, surrounded by a positive screen 11, an earthed screen 12 and the anode 3, the electrodes are alternately supported from opposite sides as shown. The electrodes 3,12 are supported from the fins on the electrodes 11, 2 with interposed mica blocks 13. The grid 12 may be connected to the control grid 2, the corresponding mica blocks being omitted. In all arrangements, the grid may be oxidized to reduce electron emission. To promote cooling, the electrodes may be blackened, roughened, or perforated, for example, the fins on the electrodes 3, 12, Fig. 3, may be perforated. The fins may be fluid-cooled directly or indirectly; one support 7 may be hollow to receive circulated water. The interelectrode gaps may be of the order of 20 mils or less.

Filed: 1928-08-14
Abstract: 321,469. Whitehouse, J. M. Aug. 14, 1928. Ratchet and like step-by-step conveyers.-In a convever for coal &c. wherein the material is conveyed along a trough by the reciprocation of a set of transverse wedges relatively to another set of similar wedges, the wedges of each set are capable of a rising and falling movement., and the wedges of each set ride upon those, of the other set alternately according to the direction of movement of the conveyer. The movable wedges 5, Fig. 1, are pivoted at 6 in longitudinally slidable bars 2 disposed adjacent to each side of the trough. The fixed wedges 4 are pivoted at 8 to the bottom of the trough. Accumulation of material under the wedges is prevented by forming recesses 10<a> on their underfaces and perforations 10 in the bottom of the trough. The passage of the sliding wedges under the fixed wedges is facilitated by providing the latter with ribs 9 having undercut edges. Similar ribs may be formed on the sliding blocks to facilitate their passage over the fixed blocks. The inclined faces of the wedges may be serrated or formed with steps. In a modification the wedges are not hinged. The thickened ends of the bars 2 slide in longitudinal slots 11, Fig. 5, formed in the trough sides and are bolted to the sides of a carriage 12 which extends beneath the trough and is slidable longitudinally of the conveyer upon two parallel spindles 13. A cradle 14 secured to the trough is pivotally mounted upon a part 14<a> of the reducing gear through which motion is imparted to the bars by a motor 15. A member 17 pivoted at 16 to the cradle 14 engages a central recess in the carriage 12 and is slotted to receive a block 19 mounted on the pin 20 of a crank driven by the reducing gear. In further modifications either the fixed or movable wedges may be formed as integral parts of the trough, and reciprocation may be imparted to both sets of wedges.

Title: Improvements in and relating to electric actuators
Inventor: BENTLEY JAMES SYDNEY
IPC: F16H25/20
Filed: 1957-07-24
Abstract: 856,160. Control of motors; controllers. TELEFLEX PRODUCTS Ltd. May 9, 1958 [July 27, 1957], No. 23432/57. Class 38 (3). [Also in Group XXX] The shaft 9 of an electric motor driving an actuator is geared to a threaded shaft 17 which is allowed to have limited axial movement in either direction. A non-rotatable nut 32 engages thread 18 and is fixed to a tubular ram 34 carrying an apertured fork for a connecting-pin, a sleeve being provided to protect the projecting portion of the ram from dust. A hollow cylinder 47 is mounted in thrust bearing 41, a portion of the shaft 17 which comes within the cylinder having a sleeve 50 in sliding engagement with pressure-plate 52 forming an abutment for gear-wheel 16. A compression spring 53 resists relative movement between the plate 52 and flange 51. If the shaft 17 is pulled downwardly, the plate 52 is not moved, but the downward movement is imparted to the flange 51 through nut 55 and thrust-sleeve 54. Alternatively, if the shaft is pushed upwardly, the flange 51 remains fixed but the gear-wheel 16 abuts the pressureplate 52 to move it over the outer surface of the sleeve 50. A sliding rod 56 has a fork member 59 embracing the gear-wheel 16 and is adapted to actuate limit switches 62, 63, by means of collar 79 between plates 72, 73. Thus, upward movement of the rod 56 causes collar 79 to engage plate 72 so pushing a plunger which opens the switch 62 and stops the motor. Owing to spring 78, the plate 73 is drawn away from the switch 63. The motor is similarly switched-off if the rod 56 is moved downwardly due to the maximum loading, as set by the springs 53, being exceeded. In addition to the load-sensitive means, the actuator may also be provided with travel-sensitive means operating on the same two limit switches. For this purpose, a fixed guide rod has two blocks adjustably secured to it by means of clamping screws which constitute pivots for a pair of twoarmed levers. A rod moving with the ram of the actuator, has abutments for engaging the levers at the limits of travel so that a striking rod 90 having sleeve 93 actuates switch 62 or 63. A removable crank handle 22 allows manual operation of the actuator. In another arrangement, the screw of the actuator moves axially and is held from rotation, whilst the nut rotates and is held from axial movement, Fig. 6 (not shown).
