Abstract: 600,744. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., and LEWIS, T. X. Feb. 19, 1945, No. 4101. [Class 38 (iii)] Contactors 2<11>-5a<11 >for cutting starting resistance 12 out of the circuit of D.C. motor M have the circuits of their coils C2-C5a selected by controller 13 and then energized in succession through relay I which opens on excessive motor current and relay Cx-which may be slugged by a parallel resistance-having contacts x which connect the contacts 19 of relay I alternately to one group of coils (C2-C4) and to another group (C3-C5a). Shunt field diverter contactors 7" and 8<11> have their coils C7 and C8 similarly controlled. Each contactor can maintain itself bv contacts 2-8 and prepare the circuit for the next in succession by contacts 2<1>-4<1> and 6<1>-7<1>. The circuit of coil Cx is made and broken alternately by contacts 2<111>-7<111> and 3<111>-8<111>. Controller 13 first energizes coils C1 and C1 to close line contactors 1 and 1a to start the motor as a series motor ; next it energizes coil C6 to close shunt field contactor 6 to accelerate the motor as a compound motor. Further contactors, depending on how far controller 13 is moved, operate in sequence under joint control of relays I and Cx. Before coil C7 is energized, contacts 5a<1> re-open the field contactor 6. Relay I may include a coil Ir which is shortcircuited by contacts 3<11> to alter the current at which the relay operates. Sluggishness of relay I may be reduced by an extra operating coil either in series with coil Cx and shortcircuited when the relay I lifts, or momentarily energized, through a transformer and rectifying arrangement, when current through contacts 19 is switched on or when coil Cx is switched on and off. Braking.-Brake controller 14 first shortcircuits contacts 19 and de-energizes contactors 1 and 1a and then, through contacts 1<1> and 1a<1>, energizes contactors C9 and C10 to close the braking circuit through contacts 9<1> and to short-circuit shunt field resistance 27 by contacts 10. Lastly controller 14 energizes contactors C2, C5a and C6.

Title: Control means for toy electric racing cars
IPC: A63H18/02
Filed: 1966-02-01
Abstract: 1,142,231. Control for toy vehicle on track. A. E. GOLDFARB. 1 Feb., 1966 [1 Feb., 1965], No. 4364/66. Heading A6S. The operation of a toy vehicle on a track supplied with electric power is controlled by a rheostat connected to the power supply, and a simulated pit stop control connected to the rheostat so as to override its normal operation and supply a minimum amount of power to the track after a predetermined amount of use of the rheostat. As shown rheostat coil 68 is controlled normally by slider 61 operated by knob 142. Each time the knob is moved to the left, dog 234 engages a tooth 232 of ratchet-wheel 228, causing it to rotate counterclockwise by one increment. After one revolution, cam 226 on wheel 228 engages cam 242 on latch 206 lifting the latch out of the position of contact with vertical section 194 of plate 188, shown in Fig. 5. Plate 188 moves to the right under the influence of spring 200: the resulting movement cam 215 causes spring 216 to open the circuit at contact 222 and close it at contact 218, placing the full resistance of coil 68 in the circuit to the track and thereby slowing the vehicle. To restore normal operation, the vehicle is moved from the track to a simulated pit stop 150 (Fig. 3). Protuberance 41 engages lever 168 and pivots it about pin 170, bringing end 175 into engagement with plate 188. Plate 188 is pushed to the left, so that the circuit is again closed at contact 222. This position is maintained against spring 200 in that operation of knob 142 as the vehicle slows down will rotate wheel 228 and disengages cams 242. arid 226, so that latch 206 will move into the position of Fig. 5 under the influence of spring 242a. A steering bends in the track) may also operate the wheel on shaft 89 (for turning the car around simulated pit stop control. As shown, when the wheel is turned clockwise, lug 266 engages arm 258 to swing plate 248 about pivot 260 thus bringing dog 250 into engagement with teeth 232 of ratchet wheel 228 in the same manner as dog 234.

Abstract: 1,183,145. Cooling discharge tubes. R.C.A. CORPORATION. 29 Jan., 1968 [27 Jan., 1967], No. 4423/68. Heading H1D. [Also in Division F4] A discharge tube 49 is cooled by a heat pipe which comprises inner and outer walls 52, 50 defining a closed space 54 in which a continuous capillary structure 62 lines the inner surfaces of the wall regions and which contains a working medium vaporizable at the operating temperature of the region, and the inner wall 52 of the heat pipe is in heat transfer relation with a region of the tube which is heated during operation. As shown, the walls 50, 52 are tubular and define an annular space 54, and inner wall 52 constitutes the anode of the tube. The working medium may, for example, be water or caesium, depending on the desired operating temperature, and heat conducted through the relatively thin anode wall vaporizes the medium in the capillary structure which vapour then condenses on to the relatively cool outer wall 50 where it gives up its heat of vaporization and is recirculated. To assist in dissipating the heat, the outer wall 50 may have heat radiating fins 64, 66, which may themselves be in the form of heat pipes, Fig. 4 (not shown). The end wall 60 of the anode may be modified as shown to provide a heat dissipating path between grids 68, 70 via insulating ring 72, e.g. of BeO, to the capillary structure 62. A plate 74 with no capillary structure behind it may be disposed in the end wall 60 to prevent unwanted cooling of the adjacent cathode 76 and its heater 78.
