Title: Method and apparatus for cutting sugar cane
IPC: A01D45/10
Filed: 1971-11-19
Abstract: 1424511 Apparatus for cutting sugar cane F W McCONNEL Ltd D A SCOTT and J C HUDSON 17 Nov 1972 [19 Nov 1971] 53957/71 Heading A1F An apparatus for cutting sugar cane comprises passing in one direction through the growing cane combing elements 28 for combing a stretch of cane, a pressing element such as a cross-bar 17 for pressing the combed canes towards the ground in the direction of travel, and severing the pressed canes by cutting elements 49 such as cutter blades 78, for the cutting elements 49 being power driven. The combing elements 28 and the cutting elements 49 are located at the front and rear respectively and on either sides of a tractor 10. The combing element 28 is preferably driven by a hydraulic motor 41 in a direction such that helical ribs 29 on its surface tend to lift the tangled cane clear off the ground as it passes between the combing elements 28. The combing element 28 is supported by a bracket 27 which is welded to a beam 25 and shoes 26' having a tine 30. The beam 25 has a longitudinal slot (26) Fig. 3 (not shown) in which are received rollers 23 and 24 mounted on brackets 21 and 22 of the upper limb section 16' and lower limb section 16" of a limb 16 of a swingable support structure 14. The beam 25 is therefore slidably mounted on the limb 16 so that the shoe 26' may always remain in contact with the ground despite its uneven surface. An hydraulic ram 19 is pivotally mounted between a plate 18 which is welded with limbs 15 and upper limb section 16' and plate 20 whereby extension of the ram 19 raises the support structure 14. Each of the cutting elements 49 is mounted on a support structure 42 and comprises a transmission casing 50 having bearings in which is rotatable a horizontal shaft 51 having a sprocket 54. An endless chain (55) Fig. 5 (not shown) drives the sprocket 54 and a further sprocket 56 mounted on a shaft 57 and which is rotatable in bearings 58 mounted on a structure 48. The shaft 57 is connected through a universal coupling 59 to a power-take-off shaft 60 whereby drive is transmitted to a vertically disposed shaft 52 which shaft 52 extends down through a casing 53 and drum 85 for rotating a hub 62 having pivotally mounted shafts 70 which carry the cutter blades 78. The shaft 52 is rotatably mounted on bearings 61. A ring 82 and cap 80 define apertures 83 for providing outlets for the extension and pivotal movements of the cutter blades 78. The cutter element 49 on the other side of the tractor 10 is similarly operated. Since the blades 78 are pivotally mounted it is possible for them to follow the contours of uneven ground. The cutting elements 49 are adapted for contra rotation in synchronism.
Patent GB-543765-A (GB)
Abstract: 543,765. Screw conveyers. FEHLING, H. R. May 11, 1940, No. 8508. [Class 78 (i)] [Also in Group XI] The grate of a cooking range, heater, boiler, stove or the like is fed upwardly with solid fuel by a vertical or inclined screw rotated intermittently or continuously and the primary air for combustion is supplied to the grate by a fan through a perforated plate or like throttling device presenting so high resistance that the rate of air supply remains approximately constant irrespectively of variations in the resistance of the fuel bed and chimney draught. In the cooking range shown the fuel is fed by a screw 14 from a hopper 1 through a vertical tank 3 to a hollow annular grate 4 having an inclined upper surface. The grate 4 is formed at its lower edge with spaced projecting bars 20 between which the ash falls to a removable ash pan 22 or ash pit which may be fitted with a water flushing device. The screw 14 may consist of an upwardly tapering hub 15 formed with one or more helical blades 16 or the blade and lower part of the trunk 3 may be tapered to prevent the fuel slipping backwards towards the hopper. A fan arranged in a box 17 supplies primary air through a throttling device to the grate 4 from which it issues through ports 9, 10. Secondary air is supplied above the grate from the box 17 through an outlet 18, the ratio between the primary and secondary air being regulatable by a knob 19. The screw and fan may be driven intermittently or continuously by motor, handwheels, or springs. The driving means if separate, may be linked together. The hollow grate may be partitioned into two compartments having air ports at different levels. The pressure air may be supplied only to the back of the fuel bed, the escape of combustion gases through leaks in the range being thereby prevented. A suction fan may be arranged in the exhaust flue and driven from the same or a different motor from the pressure fan.

Abstract: 1453457 Railway track maintenance machines MATISA MATERIEL INDUSTRIEL SA 23 Nov 1973 [19 Jan 1973] 54537/73 Heading E1G [Also in Divisions F2 and G3] In a rail-mounted ballast excavating and cleaning machine wherein ballast 9 beneath the track 5 is excavated by a chain loop 10 and conveyed to vibratory-screen cleaning apparatus 15 from which the cleaned ballast 16 is returned to the track (as by orientatable conveyor 20) while the waste 18 is discharged either to the track side or to trucks (conveyors 21, 22), the speed of advance of the machine along the track 5 is' automatically 'varied to prevent changing ballast conditions (e.g. humidity, sizing, contamination) from under or overloading one or more parts of the machine, the machine being driven by an undisclosed variable-speed drive 27-7-8-6 controlled by one or more devices measuring such parameters as the torque on the excavating chain drive (device 23) or the weight per unit time of ballast being conveyed into or out of the apparatus 15 (devices 24, 25, 26). Each of the weighing devices 24.... 26 comprises an electrical balance wherein the belt load, measured by a roller and balance, is multiplied by the belt speed, measured by tachometer. Fig. 2 indicates how the signals from the torque dynamometer 23 and weighing devices 24.... 26 can be combined to actuate the device 27 (such as a solenoid valve) controlling the variable speed drive 8 so that the machine is accelerated if both the screen and the excavator chain are underloaded, but is decelerated if either the cleaning apparatus or the excavator is overloaded.  In Fig. 2 the two output signals 25 and 26 of the cleaning apparatus are added at 28 and compared at 29 with the ballast input signal 24 (fed through a magnetic loop or other time delay 30) to yield a decelerating signal 31 or an accelerating signal 32 according to whether the cleaning apparatus is over or under loaded. Similarly the excavator torque 23 is compared at 33 with a predetermined threshold to yield a decelerating signal 31 or accelerating signal 32. A relay 34 ensures that any decelerating signal in line 31 opens contact 35 to override any decelerating signal. A data presentation device 36 facilitates the pre-selection of machine speed range according to the required cutting depth (e.g. by a variable-length connection between a piston rod of device 27 and the control of variable speed drive 8).
