Title: Implements for the displacement of crop lying upon the ground
IPC: A01D78/10
Filed: 1972-10-09
Abstract: 1411817 Hay making machines C VAN DER LELY NV 9 Oct 1972 [11 Oct 1971] 46516/72 Heading A1F A raking implement comprises two frame beams 1, 2, carrying rotary rake members which are arranged to pivot from a working position (Fig. 1) to a transport position (Fig. 8) in which the overall width of the implement is not greater than the width of two adjacent rake members and the distance between the inner ends 10, 11 of the beams 1, 2, is less than when they are in the working position. The rake members may be mounted on the implement to rotate about substantially horizontal axes but in a preferred construction rake heads 3, 4, 5 and 6 rotate about substantially vertical axes. Rods 14, 15 are rigidly connected to the outer ends 12, 13 of the beams 1, 2 and have their inner ends pivotally are universally pivoted to a member 16 on a draw bar 33 so that they may pivot about a respective horizontal and vertical axis. Draw arms 25, 26 are rigidly connected to the rods 14, 15, the inner ends 10, 11 of the beams 1, 2 and are pivotally connected to the draw bar 33 by horizontal detachable pins 29, 30 which are coaxial with the aforementioned horizontal pivots so that the two frame beams 1, 2 may move vertically and independently of each other in response to ground undulations. The implement is changed for transport by detaching the pins 29, 30, rotating the beams 1, 2 and reels 14, 15 about the respective vertical pivot and interconnecting the outer ends of the beams 1, 2 by a coupling rod 42. A lug 47 is provided on the beam 2 to hold the end of a drive shaft 108 when it is disconnected from a towing vehicle's power take off. Other Constructional Details: The drive shaft 108 is connected to a gearbox 58 which has one output shaft driving the rake heads 5, 6 in opposing directions and another output shaft similarly driving the rake heads 3, 4 via a telescopic universally jointed shaft 106. Each rake head is rotatably mounted via a sleeve to a fixed vertical axle which carries at its lower end a fixed plate halving two apertures offset by 90‹. A ground castor wheel is mounted by another sleeve to a lower extension of the axle and this sleeve carries a spring loaded pin which enters one of the two apertures to correctly orientate the wheel with respect to the associated frame beam in either the working or transport position. Further apertures may be provided in the fixed plates to be engaged by the associated pins so that the frame beams are inclined to the direction of travel A in the working position because of the chosen angular setting of the wheels. Each wheel is associated with a cranked, screw threaded spindle by which the working height of the rake heads are altered. Each of the frame beams may have more than two rake heads and at least one further frame beam may be connected to the outer end of the frame beam 1 and or the frame beam 2 so as to be turnaible about a pivotal axis which is substantially parallel to the direction A.

Abstract: 1,131,504. Tuned interconnectors for A.C. networks. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 17 Oct., 1966 [3 Nov., 1965], No. 46555/65. Heading H2H. In a tuned interconnecting arrangement for two A.C. networks of the type in which a seriesresonant LC combination 3, 4 is detuned at a predetermined current by saturation of a reactor 5, thereby to limit the current under abnormal (fault) conditions, saturation of the reactor is assisted by a transformer 8 whose primary and secondary windings MP, MS are connected as shown. Normally the voltage across the winding MP is substantially zero due to the low impedance of the combination 3, 4, but when reactor 5 begins to saturate the combination impedance rises to increase the voltage across the winding MP and the current in the winding MS, so accelerating the saturation of the reactor 5. A reverse action occurs when the system is restoring to normal, the transformer 8 thus assisting such restoration. A resistor 7 provides an oscillation-damping effect and may be incorporated as ohmic resistance in the transformer 8 or may be connected to a tertiary winding thereof or in parallel with part or all of the winding MP or MS. Alternatively the resistor may be connected in parallel with predetermined portions or the whole of the combination 3, 4, the connections being such as to ensure zero voltage across the resistor under normal operating conditions. Winding MP may be connected across portions of the members 3, 4, again with connections to ensure zero voltage under normal conditions. If resistor 7 is in parallel with the winding MP, the right-hand end of this winding may be connected to the junction of the members 5, 6. Resistor 7 may be replaced by a reactive impedance connected to a tertiary winding of the transformer 8.

Title: Device for achieving voltage unbalance in the windings of an asynchronous motor
IPC: H02P1/02
Filed: 1973-10-09
Abstract: 1457111 Inductors G SELAM 9 Oct 1973 [10 Oct 1972] 47132/73 Heading HIT [Also in Division H2] A polyphase squirrel cage induction motor M is controlled by a variable impedance 1 operable during starting of the motor to reduce its current and optionally during running and/or stopping to control its operating and/or braking torque.  Construction of the impedance 1.-As shown in Fig. 1, a coil 2 is wound around a mandrel 3 coaxial with a tube 4 which guides a plunger core 5 and has cooling fins 6. Members 2, 3, 4 are disposed in a housing 13 whose lower end has ventilating apertures 14 and whose upper end contains a block 7 of magnetic material, through which passes a screw integral with a washer 10 serving as a stop for one end of a spring 9, whose other end is located in a recess 12 in the core 5. Adjustment of a setting nut 11 determines the compression of spring 9. Operation of impedance 1 and motor control thereby.-With the motor switched off, the core 5 rests at the end of tube 4 causing the coil 2 to have a low ohmic impedance. When the motor is switched on, the high starting current energizes the coil 2 to draw the core 5 into it to an extent dependent on the value of current and the setting of spring 9, the impedance of the coil 2 thus increasing to limit the current in the corresponding phase of the motor and so unbalance the supply to its windings during the starting period, at the end of which a switch 1a (responsive to the motor speed or manual actuation) is closed to short circuit the coil 2. If switch 1a is not closed, the motor will operate at a torque lower than its nominal value and determined by the setting of spring 9. The effect of the spring may be overridden by inserting a block at a point in the air gap of the coil 2 to prevent travel of the core 5 past this point. If the motor is driven by its load at a speed above its synchronous value, the coil 2 reduces one phase current and unbalances the winding currents to produce a braking action prior to the motor stopping.
