IPC: A01D17/00
Filed: 1964-01-28
Abstract: 1,103,612. Root-crop harvesters. C. MOFFETT, 17 March, 1965 [28 Jan., 1964], No. 3489/64. Heading A1F. [Also in Division B7] A potato or beet harvesting machine comprises a tractor 1 suitably modified by mounting the rear axle 3 and final drive mechanism 4 in reverse fashion beneath the gearbox 2 with the final drive input connected to the gearbox output by a chain drive within a casing 6, a cleaning drum 20 mounted at the rear of the machine and driven from a power take-off shaft 7 extending rearwardly from the gearbox 2, crop lifting means disposed forwardly of the axle 3, and means driven from the power take-off shaft 7 for transporting the crop from the lifting means to the cleaning drum 20. The front wheels 9 of the tractor are mounted on a transverse member 10 at the front of a frame 12 attached to the tractor, and are steered by the steering wheel 14 through links 17. A haulm cutting device 57 adjustable vertically on links 58 by a linkage 59, 60, 61 includes knives or flails on a shaft 62 driven through chain drives 63, 64, a shaft 66 and chain drive 67 from a shaft 34 connected by a chain drive to the power take-off shaft 7. A sub-frame 35, 36 suspended by shackles 37 from the casing 6 and adjustable vertically by a linkage 39, 40, 41 connected to a hydraulically-actuated crank 42 carries coulters 48 and a tined disc 47 driven by a universally-jointed shaft 49 coupled to the shaft 34. The sub-frame 35, 36 is displaceable rearwardly against the resilience of a spring 43 (Fig. 4, not shown) to avoid damage upon meeting an obstacle. Potatoes lifted by the coulters 48 on to the tined disc 47 are delivered by a conveyer 53 to the cleaning drum 20 which is rotated by a rubber-tyred wheel 25 driven through chain drives 27, 30 and a gearbox 28 from the power take-off shaft 7. The potatoes are raised by vanes within the drum 20 and discharged upon a cleaning device 68 comprising intermeshing ribbed rollers 69 driven by a flexible drive from the shaft 66. A conveyer 70 receives the potatoes from the cleaning device 68, and a rotating roller 88 diverts the larger potatoes to one side of a fence 90 for delivery to a shoot 92 which fills sacks attended by an operator on a platform 93. Small potatoes or stones which pass below the roller 88 or are thrown over the fence 90 by operators on a platform 85 fall to the ground at the end of the conveyer 70. Both the cleaning device 68 and the conveyer 70 are tiltable to compensate for ground inclination, about a longitudinal axis by a lever 78, and about a transverse axis by a hydraulic ram 81 (Fig. 4, not shown). The conveyer 53 may be replaced by a ladder of ribbed rollers acting as a cleaning device, and the conveyer 70 may be divided into more than two channels.

Title: Improvements in devices for maintaining a constant temperature or density in a liquid
IPC: F25B21/02
Filed: 1964-01-28
Abstract: 1,017,013. Cooling liquids. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 28, 1964 [Jan. 31, 1963], No. 3586/64. Heading F4H. Apparatus for maintaining a liquid at a constant temperature or density comprises a thermo-electrically cooled contact member which at said predetermined temperature or density is immersed to a predetermined depth in the liquid and is so arranged that deviation in the liquid temperature or density cause the contact member to be immersed to a greater or lesser degree to extract greater or lesser amounts of heat from the liquid. As shown, water in a flask 3 is maintained at freezing point by a pivotally mounted member 7 on which a thermo-electric cooling device 11 is mounted, the hot junctions of device 11 being connected to heat-dissipating fins 14. As ice forms on the lower part of the member 7 the latter is pivoted anticlockwise to reduce the area of contact between the member and the water and thus to reduce the rate of heat withdrawal. This rate is further reduced by a member 13 secured to member 7 which projects from the apparatus when member 7 is raised and absorbs heat from the ambient air. In one modification (Fig. 2, not shown) the thermoelectric device is fixed and contact between it and the member 7 is broken when the latter rises. In another modification (Figs. 3 and 4, not shown) the member 7 is in contact with the fixed device 11 via a mercury bath, the area of contact between the mercury and the member 7 being progressively reduced as the latter is raised. The lower end of the member 7 may be hollow and filled with the liquid to be cooled.
