In Fig.5, the rate of flow of fuel gas through a conduit 33 to a burner heating fluid passing through a conduit 31 is measured at 36, the rate of flow of combustion oxygen or air from a fan 34 is measured at 29, the oxygen content of the exhaust gases is measured at 40, and the temperature of the heated fluid measured at 32. Electrical signals corresponding to these measurements are applied in succession by one section of a rotary contact or magnet-operated switch 51 to an analog PID controller 50 which also receives, through other sections of the rotary switch, signals corresponding to a desired value of fluid temperature, selected at 52, and relative proportions of proportional, integral and differential control terms selected at 53, 54 & 55 respectively. Control signals from controller 50 are applied in succession through the remaining section of switch 51 to control valves 37 & 38 so that the supplies of fuel and air are adjusted to obtain the desired fluid temperature and oxygen content of the exhaust gases. Control of temperature takes place through a controller 56 which has provision for alternative manual control. In a modification involving both fuel gas and fuel oil burners, arrangements are provided to select automatic control of either and manual control of the other. Switch 51 may alternatively be electronic, optical, pneumatic, hydraulic or mechanical. The control signals may be indicated or recorded and the proportions of the control terms may be automatically modified by feedback.

Abstract: 1318951 Fruit picker ASHLAND CO of N J Inc 6 July 1970 32598/70 Heading A1F A fruit-picking device comprises arms which clasp and shake foliage, causing the fruit to fall into a catcher. The device 10, preferably affixed to a movable boom, has a shaker head. 12, the back-plate 38 of which is movable in the slots 54 of the tubular guides 50, 52. The guides 50, 52 are mounted on a frame 26 of channel cross-section, and the back-plate 38 contains rollers 56 and roller wheels 58 to facilitate the movement of the head. A hydraulic motor 60, having a shaft 62, is fitted to the back wall 44 of the frame 26. The shaft 62 extends through the back wall 44 and is attached to a cam 64, which has a heart-shaped cam-track 66 formed in it. Engaged in this track is a cam-follower 68 affixed to the centreplate 22 of the shaker head 12, and thus rotation of the cam causes the shaker head to move up and down with a snap action between each movement. On each side of the shaker head is a pivoted prong-support plate 14, 16, each connected to the centre-plate 22 by means of hydraulic cyinders 18, 20. These cylinders enable the prong-support plates 14, 16 to move from their position as shown in Fig. 1 through approximately 90‹, extending the attached prongs 24 into the foliage. These prongs 24 are coated with sponge or rubber 25 to minimise damage to the tree, and they clamp the foliage by means of a hydraulic motor 27 and gears 29. In operation, the cylinders 18, 20 extend the prongs 24 into the foliage, which is then clamped, and shaken by the vertical oscillation of the shaker head 12. The fruit which falls is caught by the tines 30 of the catcher 28, and can be carried away by a conveyor 32. After harvesting, the prongs 24 are opened and retracted, and the shaker is repositioned for further operation. In a further embodiment, the prongs may be made self-expandable through an internal mechanism of pneumatic expansion means to effect a grip on the foliage.
