Title: Improvements in or relating to agricultural machines
IPC: A01B41/06
Filed: 1960-05-25
Abstract: 910,355. Locating conductive bodies. SOC. D'EXPLOITATION DE BREVETS DE MACHINES AGRICOLES S.A. May 25, 1960 [May 27, 1959], No. 18583/60. Class 37. [Also in Group I] Apparatus for the control of implements on an agricultural plant-thinning machine having a plant detector comprises a pulse generator providing a pulse for each predetermined increment of forward travel of the machine and a pulse counter connected by an electronic gating circuit to the pulse generator, the pulse counter providing signals to control the implements when the gate has been opened by a signal from the detector dependent on the presence or absence of a plant. Fig. 2 shows a plant-thinning machine comprising a rotary cutter 7 driven by a shaft 13 and having a wheeled support 15 and a mudguard 12. The knives 8 are normally retracted out of the path of the plants by means of an electromagnet 11. The electronic control gear is contained in a box 10 and may use valves or transistors. A pulse generator comprises a Maltese cross, perforated disc or toothed wheel coupled to one of the non-driving wheels of the machine and interrupting the light incident on a photo-electric cell (Fig. 3). Each pulse is thus indicative of a predetermined forward movement of the machine. The pulses from generator 16 are normally prevented from reaching the counter 21 by a gating circuit 17. When the machine is driven from left to right along a row of beetroot shown in Fig. 1, the knives 8 remain retracted by the electromagnet 11 until the first beetroot contacts a plant-detecting feeler 9, when a circuit 19 is brought into operation changing over a bi-stable circuit 18 which opens the gate 17, thereby allowing pulses to be fed via a shaping circuit 20 to counters 21, 22, respectively operating on units and tens. When a predetermined small number of pulses has been counted (sufficient to enable the knives to pass plant 1, the bi-stable circuit 23 is thrown over, operating a switch 24, releasing the electromagnet 11 and hence lowering the knives 8 to their operating position. The remaining plants are then removed over a distance e whilst the counters 21, 22 are counting a second predetermined number of pulses dependent upon the plant spacing required. When this number is reached the bi-stable circuit 23 is changed back, re-energizing electromagnet 11 to withdraw the knives so that plant 5 is retained. At the same time, bi-stable circuit 18 is changed back, closing the gate 17 until the next plant is detected by the feeler 9. Modifications.-The photo-electric generator 16 may be replaced by an electrical generator of the rotating commutator, electrostatic or electromagnetic type. In Fig. 3A (not shown), the knives 8 are normally in their operative position, a first signal causing them to retract and a second signal to return to their operative position. A third counter is provided to control the gate 17.

Abstract: 971,416. Shoe-drum brakes. D.B.A. S.A. May 10, 1963 [May 11, 1962], No. 18629/63. Heading F2E. An internal shoe-drum brake comprises two arcuate brake shoes 12, 14 which are adapted to be applied against a rotatable drum 10 through the intermediary of intermediate levers 30, 32 pivotably mounted on a backing plate 40 by an actuating mechanism comprising a lever 60 pivoted on the intermediate lever 32 and a strut 64 connecting the lever 60 to the intermediate lever 30. As shown, each shoe takes abutment on the respective intermediate lever through bearing members 44 which permit the shoe to slide and pivot on the head of a screw 46 screwed into the respective intermediate lever and which serves to adjust the position of the shoes. When the brake is in the inoperative position the intermediate levers 30, 32 are held against an abutment 42 by the return spring 58. The shoes may also be applied against the drum by the hydraulic piston-cylinder device 24, the pistons 26, 28 of which act via push-rods 34, 36 on the intermediate levers. In another embodiment two floating hydraulic cylinders are disposed between the adjacent ends of the shoes and act via intermediate levers pivoted to the backing plate. A lever and strut similar to the lever 60 and strut 64 is provided to actuate each of the adjacent ends of the shoes, the two levers being actuated by a cable and its sheath. The brake thus acts as a double leading shoe brake in both directions of rotation.

Title: Improvements in wireless signalling systems
IPC: H03C1/60
Filed: 1920-07-06
Abstract: 146,881. Western Electric Co., (Assignees of Arnold, H. dc F.). Dec. 1, 1915, [Convention date]. Wireless telegraphy and telephony.-In signalling systems in which high frequency carrier waves of frequency Q and a signalling wave of frequency P are impressed upon a modulator to produce in its output circuit modulated carrier waves which may be regarded as composed of three waves of frequencies Q, Q + P, and Q-P, a. resonating system is associated with the output circuit of the modulator to suppress the unmodulated component Q, or the unmodulated component Q to. gether with one of the modulated components Q + P or Q - P. Fig. 1 shows a wireless trans. mitting station arranged according to the invention. Carrier waves of frequency Q, generated by the oscillating valves, are impressed upon the input circuit of the modulator 5, the amplifying power of which is varied in accordance with the waves of signal frequency P in the microphone circuit 2. Modulated carrier waves in the output circuit of valve 5 are impressed upon an intermediate resonating system consisting of the resonant circuit 7, tuned to the carrier frequency Q, and a pair of resonant circuits 8, tuned to the frequencies Q + P and Q - P respectively. The system presents a small impedance to waves of frequency Q + P and Q - P, but a substantially infinite impedance to waves of frequency Q, thereby preventing the passage of unmodulated current of carrier frequency. Waves of the two transmitting frequencies, Q + P and Q - P are amplified by the amplifiers 10, 12, and delivered to the aerial 14. In a receiving system, Fig. 2, for use in connexion with this transmitter, power is transferred from the aerial 15 to a system of resonant circuits similar to that used in the transmitter, comprising a circuit 17 tuned to the carrier frequency Q, and a pair of circuits 18 tuned to the frequencies Q + P and Q - P. This system is coupled to the circuit 20, which receives oscillations of carrier frequency Q from the generator 26, and is coupled to a detector 22 through a transformer 21. By suppressing, in addition, one of the modulated components, Q + P or Q - P, the system may be used for secret transmission of messages. The invention may also be applied to ordinary line telegraphy or telephony. Specification 102,503 is referred to.

Title: Mechanism for protecting boiler feed pump
IPC: F01K9/02
Filed: 1952-07-28
Abstract: 709,046. Fluid-pressure servomotor-control systems ; valves ; flowmeters. HAMMEL-DAHL CO. July 28, 1952 [Sept. 22, 1951], No. 18980/52. Classes 69 (1) and 135 A boiler feed system includes a supply reservoir, a pump for feeding the water to the boiler through a spring-loaded metering valve responsive to the flow therethrough, a bye-pass conduit from the pump output back to the reservoir, and a valve in the bye-pass conduit coupled to, and controlled by, the metering valve. In an embodiment, the output from the main feed pump lifts a spring- loaded check valve 73, Fig. 2, and passes out through conduit 71 to the automatically-actuated throttle valve controlling the flow into the boiler. Valve 73 is of inverted-cup shape with recesses 78 around the rim and it is provided with guide vanes 80. A pointer 105 carried by the stem of the valve rides against a scale 109 to give an indication of the amount of lift of the valve and, hence, a measure of the flow. When the amount of water flowing into the boiler is sufficiently low to require unloading of the excess pressure developed by the pump, valve 73 will be lowered and an abutment 106 thereon will contact and rotate a lever 129 about its fulcrum 131 so that the other end will lift a valve 119 on to its upper seat to shut off the flow of a pressure fluid from the actuating chamber 53, Fig. 1, above a diaphragm connected to a valve 37. The latter will thus be lifted by a spring 45 loading the diaphragm, and a bye-pass passage 31, 32 leading from the outlet of the pump back to a reservoir will be opened. Valve 37 is slightly less tapered than its seat 34 and it is provided with a number of grooves in order to resist erosion. The pressure liquid controlled by valve 119 is obtained from the output of a booster pump feeding the main feed pump. Should valve 119 fail, the continued movement of lever 129 will cause a cranked arm 150 carried thereon to contact an adjustable abutment 149 on a further lever 147 pivoted at 147<SP>1</SP>. The lever 147 will thus be actuated and a valve 141 carried thereby will be lifted on to its upper seat, and as valves 141 and 119 are in series in the line leading the pressure liquid to chamber 53, the flow will, in any event, be cut off. A groove 122 in the lower part of valve 119 allows the pressure liquid which does not flow to port 117 and so to chamber 53 to be diverted to an exhaust passage 125.
