Title: Improvements in or relating to potato-harvesting machines
IPC: A01D17/14
Filed: 1948-10-25
Abstract: 655,815. Digging root-crops. BONELLA, A. G Oct. 25, 1948, No. 27649. [Class 6(iii)] A potato-harvesting machine includes a hingedly-mounted tray 15 adapted to receive the crop, the tray being tiltable periodically by a cam 23 at such a rate that the potatoes roll off it before stones and other debris. The crop is dug by a plough 6 and is thrown laterally by a spinner 9 into a perforated drum 3 supporting the machine frame 1. The drum 3 is inclined and has a sharpened edge 7 which rolls over the haulms. The end wall 12 of the drum is formed with an aperture 14 and an adjacent basket-like projection 13 which collects the crop and carries it around to the uppermost position of the drum, where it is emptied through the aperture 13 on to the tray 15. The tray is reciprocated endwise by a cam 20 engaging the hinge-axle 17, and is tilted periodically by the cam 23 on the drumaxle 24. As the tray tilts, the potatoes roll off first and fall on to a belt-conveyer 27, and the stones fall off later on to a parallel belt 28. Operators, on seats 29, transfer material which has fallen on to the wrong belt. The material is discharged on to an elevator 30 leading to oppositelydirected shoots, one of which, 32, leads to receptacles (not shown). The belts, cam and spinner are driven from the power take-off of the towing tractor through a gearbox 10. Specification 583.865, is referred to.

Abstract: 304,382. Im Thurn, J. K., Shearing. G., and Matthews, C. Oct. 24, 1927. Thermionic amplifiers. - A cascade amplifier comprising a number of double-acting or pushpull stages I - - V1 of the type described in Specification 149,018 controlled by a piezo-crystal Q connected symmetrically between the two grids of the first stage is characterized by the provision of coupling coils L2 in the oscillatory circuit. Provision is made for maintaining the supply voltages at constant value during the marking and spacing periods, keying being effected in the manner described in Specification 203,788. The grid coils L2 have low self-inductance and mutual coupling to the plate coils L1, so that the generated oscillations conform to the fundamental crystal frequency, or to an odd harmonic. The circuit L3, C3 is tuned to the selected frequency. Balancing condensers N1, N2 &c. normally stabilize the system. Grid-biasing potential, derived from the rectifiers U1, U2, paralyze the valves V9, V10 when the key R is in the spacing position S. Simultaneously auxiliary valves V13, V14 absorb the current diverted from the high-tension supply. The valves V11, V12 are designed to allow static current to pass, so that the anode rate of dissipation remains constant. Rectified plate current is supplied through a suitable smoothing-system from an AC source; or alternatively the initial stages may be supplied with direct current, and later stages supplied from an alternating-current source. Instead of being crystal-controlled, any of the stages following the first may be made self-oscillatory. For instance, as shown in Fig. 3, a switch S may disconnect the stabilizing condensers N7. N8 and connect the grids of V9, V10 across an inductance G, so as to maintain oscillations through that inductance and the grid-anode capacities of the valves. The output from the last valve is coupled to the aerial L14 through small condensers C12 and an intermediate circuit L13, C13, the centre point of which may be earthed. The intermediate circuit and the aerial coils may be screened from the output circuit of the valve amplifier.

[Class 87 (ii)] A collapsing-mechanism for tyre-building drums having key and intermediate sections comprises a relatively movable shaft 10 and sleeve 11, the relative rotation being produced by a brake 12. The key sections 18 of the drum are connected by links 16 to a member 14 on the sleeve 11 and are also pivoted at 19 on arms 20 secured to the intermediate sections 21. The arms 20 are pivoted to a member 23 journalled on the shaft 10 and the sections 21 are also connected by links 24 to a member 25. The key sections 18 may carry spring-pressed pins 27 which latch in sockets 28 on the links 16 when the sections are collapsed, and resilient rubber stops 29 may also be provided to limit the collapsing movement. Abutments 30, 31 may be provided on the members 23, 25 to limit the outward movement of the sections 21. Hooks 32 on the key section 18 are provided to engage pins 33 on the sections 21. When the brake 12 is applied to the sleeve the sections 18 are first drawn inwardly by the links 16 to the limit of movement. Continued rotation then applies a force through the links 16 and sections 18 to the arms 20, thus fixing the member 23 relatively to the sleeve. Rotation of the member 25 applies a force through links 24 to sections 21 causing them to collapse, the movement being initially greatest at the end nearest the pivot 19. As shown in Fig. 7, the drum sections may each comprise a central member 40 carrying a shield 41 and side members 44 slidable on extensions 40<a> of the member 40 and adjustably retained by bolts 43 sliding in slots 42. To increase the range of adjustment of the side members, two alternative holes 47, 48 are provided therein for the bolts 43, and plates 45 cover the holes not in use.
