Title: Improvements in and relating to the sorting of granular material
IPC: B07B13/02
Filed: 1956-04-24
Abstract: 798,911. Sorting solid materials. SOC. DES ANCIENS ETABLISSEMENTS LHUILLIER. April 24, 1956 [June 30, 1955], No. 12577/56. Class 117 A grain sorter includes a horizontal rotatable drum, the interior or exterior suface of which is provided with pockets, a trough arranged parallel to the drum to collect and maintain in contact with the pocketed surface a mass of grains to be sorted, and a screw type conveyor arranged in the lower part of the trough such as to be completely embedded in the lower portion of a mass of grains retained by the trough. In the described embodiment the charge is divided into (a) short and light grains, (b) heavy grains of moderate length and (c) long and light grains. The drum 14 rests on two pairs of rollers 11 keyed on shafts 12 within a frame 10; one of the shafts is motor driven and the drum is friction driven in the direction of the arrows F. An axial shaft 26 is supported in bearings, and a tube 28 fits the shaft and supports a gutter 29 extending along the length of the drum. The position of the gutter is adjusted by turning the tube 28 about the shaft and securing the tube by a screw. A screw type conveyer 34 within the gutter is driven by a pinion 35 which engages a gear 36 secured to the drum. A trough 41 is adjustably supported within the drum by arms extending from the shaft 26, and the rear wall of the trough includes a pouring panel 49 which can be vertically adjusted by a rack and pinion. Within the drum and trough a screw type conveyer 45 is adjustably driven by belting from one of the shafts 12, and a similar conveyer 54 within a trough 23 external of the drum is also adjustably driven by a belt from one of the shafts 12. In operation, granular material passes under the trough 41 and forms a mass 64, the lower portion of which is driven gradually by the conveyer 45 towards the rear of the drum. The stirring action of the conveyer causes the light grains to gather at the upper part of the mass, and they flow over the wall 49 and are directed by a deflector 53 on to empty pockets 19 in the inner wall of the drum. Short and light grains are collected in the pockets and when the pockets contact the mass 64 they are already filled, and finally those grains fall into the gutter 29 and are conveyed rearwardly to an outlet spout 38. The heavy grains of the mass 64 are received by paddles 22 at the rear of the drum, and are thereby delivered to the trough 23 extending the whole length of the drum where they form a mass 65. Pockets 25 on the drum outer wall are larger than the pockets 19, and heavy grains of moderate length are collected by them and delivered to a hopper 39. The conveyer 54 feeds the material towards the front of the drum and the long and light grains gather at the upper part of the mass 65 and flow over a height adjustable wall at the front of the drum to a discharge spout.

Abstract: 907,433. Magnetic amplifiers. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. April 7, 1961, No. 12593/61. Class 40 (a). [Also in Group XXXVI] A supervisory control circuit for grouped selector switches required to step in unison from one position to another e.g. in transformer tap changing comprises for each switch a wiper 16, 17 traversing a range of contacts spaced along a resistance 14, 15. Both resistances are A.C. energized in bridge so that the inter-wiper voltage is zero for corresponding switch operation and off zero if a fault causes either switch to fall out of unison with the other. Such voltage is transformer coupled to a full-wave rectifier 9 connected over variable resistance 8 to shunt capacitance 13 which feeds control winding 6 of magnetic amplifier 1 over variable resistance 7. The amplifier comprises a pair of working windings respectively connected in series with a pair of feedback windings through oppositely poled half-wave rectifiers; the two circuits being parallelled and connected to an A.C. source 3, 4, over fault-detecting indicating device 2. A D.C. energized control winding 5 opposed to the control winding 6 normally blocks the amplifier until excitation of the latter winding under fault conditions, when retroactive currents in the winding and feedback windings produce surge response of device 2 which may also operate switching to disable the stepping switches under fault conditions so that they do not deviate one from the other by more than e.g. one position. Resistors 7, 8 are adjustable to set the time constant of the control circuit such as to prevent false indications due to minor differences of stepping switch operating time.
