Title: Seed population monitor
IPC: G01B7/02
Filed: 1974-09-20
Abstract: 1473922 Monitoring operations in seed planters DICKEY-JOHN CORP 20 Sept 1974 41013/74 Heading AID [Also in Division G4] Means for monitoring the operation of a seed planting machine includes means arranged to issue a signal, indicative of an area having been planted, when the machine has travelled a determined distance, means for sensing and counting seeds being planted in each of a plurality of rows; and means responsive to the signal to read out the counter as a measure of the seed population per unit area and to reset the counter. A wheel rolling on the ground operates a reed switching device at intervals to represent distance travelled while a lamp and photocell in each seed delivery tube issues count signals. Detailed logic circuitry is described for processing these signals (Figs. 3A, B, C not shown). Pulses from the distance wheel (70) are accumulated in a first counter (82); the latter is first preset to a value such that it reaches a full count and issues an output pulse when the machine has travelled a distance corresponding to planting 1/200<SP>th</SP> of an acre. The preset value can be adjusted by a switch (180) to allow for different row spacings. The count pulses from the various rows are individually gated to a second counter (148) which comprises a quinary counter (decoded to advance in counts of two) followed by two decade stages such as to accumulate a count of seeds per 1/100<SP>th</SP> of an acre. The value in the second counter is transferred to latch circuits (152) for continuous readout when the first counter issues an output pulse; after a delay the counter is zeroised. The individual gates feeding the second counter may be controlled by a switch (206) so the second counter (148) counts only from a selected one of the sensors or under the control of a third counter (204) successive count cycles may be derived from successive sensors. Lamps associated with the rows flash to indicate which row the current count came from. Also associated with each row are alarm circuits (not described) which illuminate the lamps if the rate of planting falls below a preset value. A further counter (104) accumulates a count reprising the total area planted. Specification 1346458 is referred to.

Abstract: 1,014,000. Control of A.C. motors. ELECTRICAL APPARATUS CO. Ltd. Oct. 9, 1964, No. 41319/64. Heading H2J. An induction motor is braked by supplying a stator winding with direct-current derived from rectifier 27 which is connected through choke-winding 19 across winding 37 of a mains-supplied auto-transformer. The choke has a saturating winding 18 whereby the impedance of coil 19 is reduced, when the rotor current increases, to increase the braking current. This enables the motor to operate at a stable lowering speed irrespective of the magnitude of the load. A discharge resistor 32, having a non-linear volt-ampere characteristic, protects the rectifier 27 against excessive voltage. The transformer may be tapped, and may be replaced by a transformer having separate primary and secondary windings. Specification 794,891 is referred to.

Abstract: 1,197,503. Reels. LEESONA CORP. 12 Sept., 1967 [31 July, 1967], No. 41559/67. Heading B8M. [Also in Divisions D1-D2] Textured yarn is collected by winding with an overfeed (and consequent relaxation) the rate of which is greater during a first phase of winding than during the second phase. The first rate may decrease and the second rate may be constant. Thus, in the wound package, the yarn in the innermost layers is more relaxed than the yarn in the remaining outer layers, so that the yarn is receptive of treatment by heat and/or moisture to modify the stretch/bulk properties with uniform results. As shown, yarn Y passes through a traverse guide 50 and is overfed to, and wound on, a tube 48 rotated by a drive roll 40. The drive is effected, for perhaps the first several hundred yards of yarn wound, through a ring 54 integral with or secured, as by a screw 56, to the winding mandrel 44 or the tube 48 seated thereon, and thereafter conventionally by dried contact between roll 40 and the peripheral surface of the package.
